07blackg5 Build Thread. Operation Moneypit
 

I am already balls deep in this project, but I will try to hit the major points. I'm mainly making this thread to get questions answered, but I will try to provide some sort of entertainment.

Got the car new off the lot. As it sat before I got started is:

-Gt bumper and lips with ss front lip, oem fogs
-tjin trunk
-gen 4 projectors, tinted corners/reverse/3rd brake
-bc coilovers
-ottp longtube header
-zzp catback
-2.4 intake mani
-fe5 control arms with
-ottp tcabs
-ottp rear sway
-prothand trans inserts
-NX n2o kit with wotbox for window switch
-custom intake (half ebay, half weapon R)
-17x9 wheels with 245/40 tires
-SSBC front and rear kit


I started of with goals of an 11:1 m62 build, but just recently steered to a TVS and factory 10:1 comp.

Build list is as follows:
-full 6 rib swap
-tvs
-option b/dual pass
-zzp stealth h/e
-zzp radiator
-lsjion ported head
-zzp s2 blower cams
-Perf Autowerks valvesprings
-stock gen 2 block (07 was gen2)
-wiseco pistons
-eagle rods
-ATI od
-zzp nbs
-GM main and rod bearings
-zzp phenolic spacer
-ls4 tb
-spec flywheel and stage 3+ clutch
-ID1000's
-lsj fuel rail
-ottp return fuel
-aem 320 e85 pump
-a/c delete

Hoping for close to 400 on the blower, and either a 35 or 50 shot depending on how close to 400 I am.

Here is how the car sits as is in terms of cosmetics.

I have a lot of pictures of the brake installs and whatnot, but thats all pretty normal stuff. Since I have an 07, the head is slightly different than the previous l61's. The cams need to be cut, and a sensor needs to be pressed on. There was a lot of ruckus about the process, but I decided to do it myself.

The exhaust cam needed to be trimmed as well, but this is both installed:

Right as winter was starting, I started playing with nitrous jets and afr, as well as nozzle placement. I have a full spare longblock, so I didnt care if I blew it up.

Welp, blew up cyl 4 haha:

This is where the bay sits as of this week. I actually have the radiator and fan pulled already. The random wires are a horn relay, the foglight relay, and the wotbox wires that were originally hidden under the fusebox. that will all be cleaned up:

That should be enough for tonight. I have a few questions lined up, but will wait until tomorrow.

Love the guts you have chopping those cams. I'd do it too if mine wasn't my only transport.

If you spent as much time reading all the bitching and moaning about it as I did, you would have done the same thing

Nice build, what are those wheels? They look sick.

Finally you made your own thread! :lol:

They are rota grid's. 17x9 +45 with a 5mm spacer in the front to clear the strut. They loog gunmetal in the picture but they are dark grey with a very fine silver flake. You cant really get a good picture of it.

I finally felt bad enough for shitting all over yours haha

First question.

The 2.2 ecu only has provisions for iat1 signals. What people have done in the past (from my understanding) is remove the temp signal wire from the MAF, and move it to the MAP (factory 2.2 map wont read temps, again from my understanding iat1 is read at the maf). That way the ecu can read the intake temp post intercooler.

I would no longer have a pre-intercooler signal, and wouldn't be able to easily tell the difference between iat1's and 2's. I have dual interceptors, and they can be wired to accept additional 0-5v signals for extra parameters. I assume that the the maf temp signal is 0-5v like the rest of the car. Does anyone knowledgeable about the electronics of these cars chime in? I figure I can run the maf temp signal wire to the interceptor as a custom input, so that it would display my "custom" iat1 reading and iat2(registering as iat1 in the ecu)

Troof. That's why I built my custom tails. Kudos. Once I get a beater this is definitely happening to mine.

I have an extra intake cam if you want to have a spare sensor to swap on, vs using the one in your car. That way you can just hot swap the cams

Once I get the car running and make sure all is well, I will let you know

Do you plan on using the 2.5 bar map from the lsj?

havent decided which route I want to go, but most likely oem lsj

Honestly I'm thinking about picking up an 07+ head and cams/springs/porting it. Someone bought the cheap supercharger I was going to go for. Maybe I can get bigger injectors and a ported head and run some E85 for now. There is only one E85 station nearby. I can't seem to find a used head for under $200 though.

Sell all parts, buy my car, profit.







And be slower.

But be yellowed and mintier

I will sell you the head I took off my car. I can even send it straight to lsjion haha. He's only a state away

Nawwww porting stuff doesn't intimidate me. Especially when I get my new grinding bits soon. :D Seems to me like shipping a head would cost out the ass. No? I do need to spend my state tax return somewhere though, if I ever get it.

it cost me 30 or 40 bucks to ship it to ohio from michigan. I cant see it being more than 50 bucks.

Do you have a valve spring compressor? that's the only thing that's really standing in your way.

Yep. I bought one to disassemble a pair of sbc heads I got for my Nova. Ported one of those so far but cast iron is a bitch and a half to get anywhere with. Focusing on the suspension on that car for right now. Have tubular LCAs and coilovers, and everything except rotors and brackets to swap 14"/13" front/rear disc brakes on it.

Let me know if you want it.

I found a few random pictures that might be interesting. From right before dom and the mad scientist had to tear down the block and replace the piston rings i fried..

Had to change my coilover cartridges and the one collar was seized. had to drill out the pressure and cut it in half. no way the collar was making it all the way down the body

I have a complete lsj head with 58k on it, not sure if I want to keep it yet, just depends on if this 2.8 will scratch my itch for a while. I could use the money towards other parts for sure. If I ever want to go faster ill probably kick myself for selling the head though. The last fwd car I had was an sc2, so if its 300% more thrill without going crazy with the car, I probably wont need a garage full of old parts.

spare parts are always nice to have, but sometimes you just need to liquidate.

LSJ head won't work on 07+ because the cam sensor. I have been toying with the idea of unplugging my cam sensor and disabling all the associated codes to see if you could run an LSJ head, but I am horribly doubtful.

I have no idea if it would work or not, im no mr.b ill tell ya that much lol. im still way new to the delta platform, but im catching up quick.

You could make it work, but its a lot of extra hassle. just random things like the cam sensor differences, the pcv ports flipped around, etc. The only thing with the 07-08 l61 head is that there is no bolt hole for the lsj fuel rail hardline support, but that is easily worked around. you will probably just use the oem rail, so it wont be an issue. as far as I understand, the l61 and lsj heads flow very similar stock for stock, but the lsj has nicer casting and what not. Once they are ported, im not sure there would be much of a difference.

Do you have a tuner? Self tune?

I own hpt, but am going to seek help.

Just bought zzp 2.2 axles, full timing kit, lsj dipstick and tube, new coil packs for good measure, flywheel bolts, injector seals, thermo housing gasket, crossover tube orings, water pump gasket, valve covergasket.

I think that's it haha. I'm getting close

Could you tell me...how or what are you doing to reattach the end's of those cams....

Lucky you have a manual. There are no axle options for auto...

Cardone select's are about the best you can do for axles for the auto's, they T6 heat treat the shafts and the CV joints are usually slightly oversized for longevity purposes. Not that that makes them amazing but they will usually withstand a little bit more HP then the stockers. Just because they are built with a lifetime warranty. Mevotech builds oversized wheel bearings as well for our cars.

The sensor is press fit, and the exhaust cam just needed to be cut down to factory length. The lsj has an extra journal on the end, while some l61s do not.

The area where the sensor pressed onto the original cam is the same size as all of the journals. So when you trim off the end of the cam that normally drives the lsj cam sensor, you are left with a floating journal. The sensor presses on that journal to the same location as with the factory cam

The few people that have had it done paid 200 plus dollars to have the cam machined down and the sensor pressed on. The only real benefit is a pretty edge. I have a press, so I decided to do it myself

But you didn't cut the cam straight and just unbalanced the camshaft. lol You do realize that spins inside the motor right? There is a reason they are cut on a lathe to make a pretty edge.

That amount of unbalanced mass is probably negligible. Nothing to worry about. It is very near the center of rotation. If it were added weight on a cam lobe or something it may be something to worry about, but not this.

Also are you pressing the sensor onto the one that you cut already?

Your probably right, I was more curious if he was going to attempt to weld the cam back together more then anything. :lol:

The cams spin at a fraction of the speed of the rotating assembly, and are a relatively small diameter. Have you seen the actual sensor? Its basically a weight hanging off one side of the cam, all else equal to the other cams with no sensor. My cuts will cause zero issues, and I would put money on it. If it were anything else, it would be a different story. As far as the end of the camsshafts, it's fine

The zzp cams have tack welds to hold the hex drive in. Do you think they rebalanced the cam after they reweld? It's negegable.

Both cams needed to be cut. The exhaust just needed to be trimmed to fit in the head, and the intake trimmed to fit, and needed the sensor. The lsj cams both extend out of the edge of the head, where neither of the 07-08 l61 cams do

I dont want to take my L61 apart to take a look at the sensor, do you have a picture of it?

I thought you had a 2.4?

I have two cobalt's, 08 and my 06 SS.
