BlackSS/SC

OK, so my plan is going full turbo. I'm looking at the T3/T4 or the GT32 type turbos. I want to make sure they will fit behind the engine good or not. I was going to run the turbo manifold on ebay that Adam mentioned in a post on here.

So I'm running stock internals right now, looking to push 320-330whp for now. I'll be looking for around 450whp after internals. The car isn't driven daily either. It's mostly used for cruizin around and going to the quarter mile track. I do want the car to be streetable though, low lag time.

So what trim and stuff should I be looking at?

Get some head work and some fat cams. The stock super will go to 500hp dont waste your time with turbo.

BlackSS/SC

Nah, I'm tried of this heat pump. It's on the fritz I think.

head/pistons... make CR around 8-8.5:1

-Jayson-

no way will a tiny M62 make up to 500HP. Not without wasting crap loads of money to do it.

Turbo is the way to go, you should easily make 350WHP on stock internals as long as you have a proper fuel setup and tune.

BlackSS/SC

I'm not touching the engine yet. I'm going turbo, the SC is no good anymore and I don't want to waste my money on another.

My suggestion:

Garrett Gt2871 Ball bearing turbo (good to 400hp) 52 trim (compressor)
Tubular Style Turbo header
Blow off valve
Electronic Boost controller
Charge pipe to Thottle Body
All Fittings for oil supply and return to turbo
Air filter
Custom Throttle Body elbow to adapt to your lower intake
Performance Clutch
Use your Stock water to air intercooler (you already have the dual pass endplate)


Options

Turbo Timer


You already have:

60lb Injectors
HP Tuners
Exhaust (downpipe and Magnaflow)

Running 20-21psi you should be in the 330-350whp range with minimal Lag, on stock internals.

Or go with a GT2876, the GT3071 will flow more but you will lose short lag, the larger GT3071 turbo will spool up above 3500rpm!

Thats why I suggest the smaller GT2871 or GT2876 Turbo, that will put you in the mid to low 12's

wow...

Very false.

I'm impressed by the suggestions here. Sounds pretty good.

are superchagers that bad? i like turbos and superchagers both, but it seems so many people just go turbo, i know the turbo holds more power in this situation but is it just our stock superchager, is there another one that can handle more power for our car?

Acidangel_5.0

superchargers gain more horsepower... turbos net more horsepower..

superchargers become far less efficient due to being belt driven with > parasitic loss + heat.. the M62 we are using is a descent blower for a stock vehicle but when wanting more.. it just isnt "big" enough for the numbers most of us are seeking... either swap the blower or swap for a turbo setup is only way to improve... need greater volumtric efficiency and a tc/sc that can get your the CFM we seek without being "redlined"

Gory

The m62 puts out more cfm than an evo 9 turbo and they get 425-450 AWHP also if you do head work and cams it will bring it into to its proper effiency range and it will no longer be a heat pump.

BlackSS/SC

Yeah but I think it will be cheaper doing a decent turbo then that.

Witt

Not saying you are right or wrong, cause I honestly don't know what the M62 is fully capable of, but if it helps, here is what Harrop lists as the max flow capability:

Flow at Max. Speed @ 1.8 Bar: 810 cubic meters / hour

If I have some time, I'll see if I can get that to a comparison of something I'm more familiar with.

If you notice, even the turbo swaps don't net much more than 320whp on average. (there are some exceptions I know, but overall) This is probably because of the stock valvetrain's limited flow capability. After partaking in djt81185's turbo swap it really isn't worth the money imo until you start modifying the top end. If you plan on keeping the top end stock, my opinion is to just go with a bottle to hit the 320whp mark, just because of the cost and ease of fabrication and installation.

everybody wants power.. but everybody wants to be cheap and think more boost will do it.. then we hear alot of crying with "i blew my **** up"... people really need to learn more about motors and stop being sheep into the demise of blown up motor heaven

Gory

I wasnt saying that making 500whp was cheap either. You will have to CNC port your head you will need a full 3" exaust, valves, springs, retainers, and some fat cams but it is possible. ps pistons and rods

Correct me if I'm wrong, but i'm thinking that a GT35 is WAY too big of a turbo for the ecotec. Using conservative figures I can see a GT3071, but not anything bigger then that. GT28 will probably be the best bet for the track, bigger is only better if you want more horsepower then you'll use in the 1/4

I'm thinking also going turbo. I was looking at the sts turbo site. This is a remount turbo installation freeing space under the hood. Also, check out on the web page there is a 2.2 L ecotec with the system installed.

I woul think that in either case you need to do engine work to get to the power goals outlined here. But if you take the ability to run turbo or SC I think the turbo is going to net more power in the end but with a sacrifice in low end due to lag. In the SAAB world using the previous gen motor (ECOPOWER) we have seen 350+ WHP on a GT2871R with proper tuning.


What options are there on porting or upgrading the stock blower on the SS/SC? Also what about using water/methanol injection to control intake temps and such?

I was gonna go with a remote mount turbo, but then found some parts that I was looking for instead, so since I've got the turbo manifold now, I'm gonna do it that way.

Ok, guys. check ststurbo.com This is a remount turbo installation freeing space under the hood.
http://ststurbo.com

There is a 2.2L ecotec with this system installed. Gains depends on the installation kit. Gains in average are more than 120HP.


One more thing. It seems it is best to use a return-fuel system. A good friend of mine has a Scion tc. He added a turbo with an aeromotive fuel pump (creating a fuel-return system) .
Lots of gains - 280 HP @ 13psi running stock internals.

Notice,
Blown #4 once because of overboost (15+ psi).

By the way, I'm Jose, an electronics and math professor on Puerto Rico.
It has been very hot these days. BTW, good info on this site.

BlackSS/SC

I'm not only using it on the track, but on the street too. I want it to be quicker than it is. I'm not touching the engine yet. I want to make sure I have a turbo I can run at lower boost and crank it up in the future once I get the internals done. The GT 30 might be the best for that?

Gory

Ok i just double checked some math and the M62 puts out the same cfm as the EVO9 turbo about 600CFM so with parisitic loss you should still be able to get around 450whp, also in addition to that you can get the supercharger ported.

BlackSS/SC

Look, my SC is toast! I'm not keeping, lets keep this on topic please.
