Ok since I've been getting A LOT of PMs asking for updates on my build, I decided to make a thread so I can update when stuff with my build happens. Well, I'm pulling the motor this weekend. The big thing that happened today was I got the pistons squared away. CP Pistons will be providing the pistons. The pistons are forged (duh), 9.5:1 compression, dual coated (teflon sides/ceramic top coating). They will have valve reliefs to acomidate (sp!?) my cam setup. CP said the pistons should handle upto 850 hp, so I ain't worried about those bad boys wussin out like the stocker :lol: They said the pistons should be at my door in 4 weeks, I'M SO EXCITED!!!!! :nuts:

Well, cast (stock) pistons pours molten aluminum into a mold, the mold is opened revieling a piston. Weak, prone to crack/break under high stress. If they get too hot, they crack. Cheap to make though.
Forged pistons are made by heating the aluminum solid cylinder to about 800*F, then uses a huge press with like 20 tons of force to press a form into the cylinder forming the shape of the piston. This is a far better process, makes a much stonger piston, and when it gets too hot, it melts, saving internal parts from flying chunks of piston. However it is more expensive to make.

theres also a negativ ehtough....forged pistons are also heavier than cast iron pistons, and thus are not as well suited to high revving, but most tuners find this a very easy sacrifice to make, as few people like making power by revving to 12kRPMs....besides hondas of course

No new updates so far. The freakin guy from COMP who was doin my cams went on vaction until the june 13th :cussing:

The guy from Ferrea is basically wating for cam specs so he can send off the valvetrain.

Pistons are still being made, they have about 3 weeks to go.

92mm pistons @ 8.0:1 compression.
EVO stage cam (the same profile)
Ti valve train
port the head
neutral balance shafts
get the cometic head gasket
of course, get a good performance crank and rods.....that'll leave more than a few cars in the dust

since hes being given everything daddy wants and skipped the real answer, ive looked into it ill tell you. you have to go to shows already and win several of them on your own or at least place well. you have to show that you can get from show to show and let people see the car and their parts on it. you dont even get much of a discount at the lower levels. something like 10% of tires once a year when i looked into nitto. and you have to put a banner going across the top of the windshield.

10:1 is a horrible compression ratio for this motor with the Eaton blower. There is so much tendency for knock, UNLESS you use a 2.8" super charger pulley for the street, and then a 2.5-2.6" for the track.

The 10:1 will make more power than the 9.5:1 at the track, but will have to be so detunes for the street that the 9.5:1 will be faster on pump gas.

We had the Banana maxed out at ~430bhp on the Aeroforce scan guage with the 10:1 pistons and 109 Octane. On pump gas it reads 280bhp, which is worse than it was on the 9.5:1 ratio.

Here's a question for all you folks saying you're going with a Ti Valvetrain:

What all parts of the valvetrain are you actually replacing with titanium parts?

Every time I dig into someones setup that claims they have a "Totally titanium" valvetrain, I end up finding they are using stainless or inconel valves with standard (put upgraded springs) and a stock cam, so the only parts they are actually using that are titanium are the valve retainers.

TCarter
06-22-2007, 01:35 PM
Higher compression pistons WILL net you more hp/tq, however your car wont like it much, and neither will the pistons.

If you can TUNE the higher compression pistons, and not have a worry in the world that they will break (or break something else...like your block) then you can do it.


However, lower compression pistons arnt necesarily better, but ALOT safer, and it allows you to shove more air into your motor.


Turbos, you can up the boost with a push of a button (boost controller) so lower comp. pistons would be best.

Superchargers, if you can find the right comp. pistons for the amount of boost your pushin, thatd be key. (alot of Trial & Error...and money)


but I look forward to seeing your updates.

In my case FULL Ti valvetrain means, Ti valves, and Ti retainers. The springs are still made out of steel. The only cars that use Ti valvesprings are like top fuel cars<-- John from Ferrea told me that.

Blown 4-banger

Nope. Ferrea all the way for me. +1 mm titanium valves, dual valve springs good for 9000+ rpm, and titanium retainers to match.

Unless you're using a different PCM, there isn't a point in going past 8400 rpm's. Honestly, if you're using titanium valves, dual valve springs will be overkill and just adding the weight you were trying to remove back.

I'd love to see a link to the Ferrea titanium valves or any other info you have on them, though.

I doubt Cameron was intending on going up to 9000 rpms. A good 8000 rpm racer would be nice.


Yeah we got La Bannana running. I was trying to explain to gilbert how he couldn't run the 2.6" with the pump gas, and spent 2 days trying to tune it that way anyways. On the race gas
(109) it says something like 430hp on the interceptor, but I still don't like the way his setup feels. Still can't wait to take it to the dyno to see how much HP it really does make.

You use titanium valves to REDUCE weight from the valvetrain, because they are lighter than stainless steal valves. Get your facts straight. Dual valve springs are only a few grams heavier than standard valve spring, but since they don't move (they do compress, but remain stationary), they don't add weight to the moving valvetrain.

Also the dual valve springs will make it that much more reliable (safe).

First off, I have my facts straight, you just mis-interpretted what I was saying. Second off, using a heavy rated spring adds to internal friction, no matter what. The weight of the spring itself does have less of an effect on the valvetrain than the valve itself, but it still is weight that needs to be moved. I'm not suggesting that you should go with the stock springs, just that a upgraded single spring would be able to handle more than you think seeing as it will have lighter valves to deal with in the first place.

Well, I'm one to "over build". For instance, I will only have around 400 whp on race gas, so I'm building my motor to handle over 700. Same goes for my valve springs, I only plan to rev to 8100, so valve springs good for 9500 with do just fine :D

GMPP themselves told me that they recommend having custom cylinder liners installed above 400 horses, or buying their race prepped block. I'm not against anything he's doing, and I tend to overkill the vast majority of my own projects. I've just decided my goals for my own build aren't quite what his are, and I've been focusing more on reducing friction than anything else, so I just thought he'd appreciate some verying opinions.

When GM tested the limits of the 2.2L ecotec, blowing many many motors in the process, they got to the point at which they had modified pretty much everything needed to make over 700 hp. Then the STOCK sleeves failed... at 740 hp.

Did you read this? Read toward the bottom where the sleeves failed, and thats on the 2002 2.2L, I'm sure the 2.0L sleeves are a little more beefy.

EDIT* However the stock Ecotec block and main/girdle structure did survive to 750 hp, as did the stock sleeves.

switching to a gt3076, should hopefully at least have the turbo in the car in the next 2 weeks or so. Selling the T-76, Evo turned out to be more of a project than I wanted (kid blew center diff along with motor that week) and I have pretty much everything I need for the next motor. Trans I might need to grab off you depending if mine holds out at the track saturday, But car's still been on the road, everything is good with it for now. Sending the cams out next week (my other head was in "limbo" since january, finally got it back this weekend and no work was ever done to it) But I"m off for 6 days starting friday, so I'll hopefully have most of the motor together and ready to go and a turbo manifold fabbed up, might even slap in a t3 super 60 I got laying around just so I can start on the tuning.

Ok, well the ceramic coating, helps the pistons take the heat from combustion. The teflon coating on the sides helps the pistons slide on the cylinder better. The oil holes, allow the oil sprayed up from the squirters to escape to the side of the piston between the cylinder and piston, to help lubricate it, and cool it better.

Fixed it for ya. I was only runnin 19-20 degrees of timing on that tune. I was also running 11.4-11.8 AFR which is richer than when I really had it tuned up, which was 25.5 degrees of timing and 11.9-12.2 AFR, that shit was retarded fast on that setup.

Good for Steve. He's keeping you from fucking up your motor. #1 Your motor will be doing nothing but screaming at 7500 rpm. #2 Stock valve springs are rated to like 7150-7200 rpm, but it lowers as you continuously rev the piss out of it. #3 I reved my car 7000-7100 rpm, and when I opened the motor there were tell tail signs that I was floating the valves, and that was at only 7000-7100 rpm. Get new valve springs, THEN rev the shit out of it, but before that, its not safe to rev that high, nor is there a reason to rev that high without aftermarket cams.

I've tuned a 7500rpm car.......he just doesn't have one. He will need cams to make power up that high, and then he will also need new valve springs, porting, and new lighter valves. If he had that we could be talking a different story, but I was trying to think with my head.

I think he thinks because some other people set their rev limiter to 7400-7500 to account for the timing pull that he can rev that high. I told him we can just add timing to compensate for the loss, but I don't know why that didn't make sense to him.

Even if he said he would never shift above 7200 I still wouldn't tune it that way, because with the tach delay and powershifting he would be up around 7800+ rpms. That's risking instant failure.

Doesn't Gilbert rev into the mid 7000s?

NOW he does, but before he blew the motor TWICE!

Only option for LSJ is cam regrinds. Blanks do not exist, I thought everyone knew about this.

AFAIK, you can techincally use 2.2 cams, but you won't be able to use our cam position sensor. All that sensor is used for is getting the motor started on first crank. I run my car without the sensor, it just takes about 5-10 crank to start, depending where you turned the car off at.

Pretty much everyone modded LSJ around here runs a 7400 limiter and takes it there everytime. So far no one has nuked their motor, and it has been over a year. LSJ starts to float at 7400ish.

Man you guys are nuts. striving for more more you abuse the motor when you could go faster just by taking advantage of our torque down low. when I run a 1/4 I dont shift passed 6200 rpm's. I would run out 3rd gear though. now with more bolt ons I wll use fourth.

I used to run every gear to almost 7gs but found not as much success shifting earlier. Used dyno sheets and annalyzed difference in engine rpm between gears to come up with a plan and shift points. worked for me. 13.9 with stage 2. only other faster GMS2 I have seen is 13.8

With my 3" Exhaust and Lightweight Flywheel, my car has no low end anymore. I have netrual balance shafts and cams waiting for the car though. Just need head work and valve springs. Plus I will be going Turbo myself once the motor is finished.

Best I could get out of mine at the track was 13.4@109. That was with shifting @ 7100ish and before the engine works, clutch, and mounts. I need to get back on the dyno and see what the power looks like.

Crane cams is doin my shit.

Steve what are you talking about when you say it pulls timing? When does it pull timing? I had my limiter set to 7200 and I would shift 7000-7100 and my car would never pull any timing.

Your car wont pull any timing unless it is the GM tunes. Running like 20+ degrees of timing on pump gas is redick. Oh I know. Also Just because your timing is advanced doesnt mean you are making any power only early detonation, right Cam haha.

What the hell are you talking about!?!? Read a couple pages back. I BOUGHT THE BLANKS! They are for the L61, the exhaust cam is shorter and doesn't accomidate the cam sensor in the LSJ head.

Fuck the cam sensor, just disable it. haha.

They do charge alot for some stuff. there header for instance is a work of art. I thought of getting it but soon realized for the more power I obtain for price for 5 hp was not worth it to me.

^^^ Exactly my point, JBP is out of the question. I don't see how they are the only ones that can produce these blanks.

THey dont produce blanks. they get them from GM for the LSJ. you get to keep your old cams.

I am not calling you guys wrong. I am just saying in our search, we came up blank. GMMP even told us they won't give out any information for LSJ blanks, or anything about their Comp grind in the build book.

If you know how to go about getting LSJ cam blanks for GM, please let us know. If JBP is the only magical way... well then I personally won't trust them, but that is just me.

JBP gets the part as easily as you can. If you cant trust them then go else where.

What are the stock cam specs again? I think going to just a hotter exhaust cam profile would be better then going with brand new cams. Our intake cam provide's us with decent low end power so a hotter exhaust cam will just give us a better defined top end.

Those are L61 cam blanks bro. I bought them and had them IN HAND. I returned them and just decided to regrind the stockers.

THey are blanks? and L61 cams are interchangble with LSJ so I did not understand what would be the problem? your getting them ground. They are on the website for the LSJ I thought.

In the build book they describe going to comp cams for performance cams.
Maybe ask Comp Cams or Crate Engine Depot.

Heres the info. I provided on a spec sheet. I did not realize at the time that the cam sensor would not work. but they do physically fit. So it made sense to me if they fit you could grind to what ever timing you want.

)))))))))))))))))))))))))))))))))))))))))))))))))) )))))))))))))))))))))))))))))))))

�� The 2006MY L61 cams can interchange with LSJ cams, both intake and exhaust. These cams are
the exact same profile, only at different timings. The 2006MY L61 timings are 116 intake, -103
exhaust. The LSJ timings are 100 intake, -115 exhaust.
�� The LNF and LE5 exhaust cams could interchange. The LNF and LE5 cams are not interchangeable
in any other way or with any other ECOtec cams.

Valve springs are the same across all variants, and should be upgraded for high-rpm operation or
increased lift.
The GM Performance Parts ECOtec cam set (88958648 set or 88958636/7 individually) is an aggressive
race cam. They are not stock-replacement cams; they require upgraded valve springs and retainers.
These cams were designed for a race motor, using the ‘06 L61 as the starting point. The cams will not fit
the 2.4L LE5 head and will not work with the stock ECM or lifters. They physically fit the 2.0L LSJ head,
but the vacuum pump / cam sensor will not work in a stock engine.

)))))))))))))))))))))))))))))))))))))))))))))))))) ))))))))))))))))))))))))))))))))))))))))

SO the question is from Comp Cams or JBP or any other producer of performance cams, do they have the timing sensors in the cams? and if not how does it work with out it?

The camshaft position sensor doesn't work with the L61 cams. The car would still start but it will take more cranks due to the PCM not knowing the position of the cams during ignition.

Actually, WOP said something on RLFs about an oil valley that prevents us from using the L61 cams. And we verified this when doing cam swaps on our LSJs. You would need to somehow block that valley where our cam sensor would be IIRC.

actually just bump your HP down a little to make it an even 400hP the tranny can handle that. it is stronger than you might think. it will handle 400HP and there are axles that will go to 400 HP too. you should be safe and save yourself alot of bother messing with the F35 tranny. but what would be really cool is if it was possible to get a f25 in there. it is a six speed!

f25 is not the greatest idea.. i dont think it has LSD. and even if it does i doubt it would be the qualife main carrier like the comp pack lsj's.. which makes the stock tranny so much stronger...good luck with your build. cant wait to see results. break into 11's or jus plain break.. jus my .2cents..

The F40 is marginally stronger but not enough for 500hp and try buying a new one. The dealership wanted $13,000US. Buy used and who knows what you are getting.
I also found a company willing to make new parts for the F35, the input/output shafts really need to be replaced. The cost for doing that was as bad as a new F40.
There is also the option of doing a race-prepped auto tranny from GM, $25,000US:nono:

I talked to Tom Shomba (sp?) who has an 1150 hp RWD Cavy and works at a local dealer ship.

Just a matter of deciding which has better gear ratios then. F25 was to be the same strength as f35.

I don't know why everyone says Neutral Balance Shafts aren't good for a daily driver. Witt has them installed on here, and I have them. You barely notice any vibes. Plus you get faster revs such as a lighter flywheel. If you already have any type of solid mount, you definately won't notice the vibes at all. Witt has just the Intense inserts on his lower tranny mounts, and he didn't notice any difference.

Now you can get a Blank? As far as exhaust not that important I would think matched flow with no overlap is important. (my questions are intended to learn). GM sells neutral balance shafts. is this a daily driver? I wouldnt do it for the gain of 10HP if it is.

Well, I talked to him on the phone, and he has an 1150 hp cavy with a 2.16L ecotec, so I'll take his word for it. He also said they are running 117 degrees of lobe seration on their car. He also said I don't as aggressive an exhaust cam as I do intake, as long as I have a good flowing exhaust (which I do).

Ok, so basically everything is done today. In terms of taking care of parts. Finally got the rods figured out. Eagle is going to supply my rods. As it turns out, the 2.2L rod is the same length as the 2.0L rod. The bearing diameter is also the same. The only difference is the pin bore is smaller (21mm vs. 23mm). I talked to Tom Shomba (sp?) who has an 1150 hp RWD Cavy and works at a local dealer ship. He said for some of their less hp motors (650-700 hp) They use the eagle rods and have the pin bore opened up. I'm going to order a GM intake cam blank, and have my stock exhaust cam reground. Tom said with good exhaust flow the exhaust cam is not as important as the intake cam with a supercharger. So I'm doing a pretty radical intake, and grinding the exhaust as much as possible. Centerforce clutches is also supplying a twin disc clutch. So basically, no I just need to get the head ported, crank machined, and neutral balance shafts made, and I can put this son of a bitch back together!!! :nuts: :nuts: :nuts: :D :D :D :twothumbs

Ahh, so you did actually get to talk to him. And its Tom Shaumbaugh.:lol: BTW, his 1150hp cavy is gonna be more like 1300 once he puts on his bigger turbo setup.;) NHRA authorized it!! You are going to put on the adjustable cam gears too right? Ain't that what he said?

Funny how I mention adjustable cam gears and you tell me they are a waste of money.
