MBWorld Fanatic!
NIce!!!!!
I'm feeling your pain 14k for a C32 *&^%$#% Might as well keep it. The Twins * turbo manifold* in our tight lil engine bay, this i got to see when your done
I was thinking swaping out my 32 motor for a Skyline Rb26det Twins 6spd but cost an arm & leg for the parts and labor. But now you guys came up with this project best of luck !!! Cant wait to see the kit
Qs, what CR ratio your guys running On your built Head ?

AMG-Jerry is practically there with his mods and I bet without his tractions issues he would be there at our elevation.....I bet at our elevation I will see mid to high 12s with my stage 1 setup...I wouldn't be surprised even if better

i like the way you think
i have never been as excited about a project for a vehicle as i am about this one...it will simply be amazing once it is complete...
that being said, the work on this begins tomorrow, i will be going by to meet with my fabricator to have him begin work on a set of turbo manifolds...once the turbos come in, then we will work on location of the turbos and begin acquiring the parts needed to make this happen!
as Jerry said, he is going to begin working on the intercooler setup...
i will be gutting a supercharger this week, should be fun to finally open one up and see what is inside...
430, i was already thinking in this direction on the turbos...in fact, there is one in particular that might simplify a lot of potential problems if all of the specs line up for what we need...
keep the questions/ideas coming...

C32
The prices of a C32 in the US is nuts ... over here in Aus, a good C32 will go for like 75-90K.....I could have bought 3 or 4 C32s in the US for the price I paid

OK, we have decided on 2.5" IC piping and 3" piping for the intake.
There are numerous ways of running the piping and even more ways of cooling the charge.... so we are going to experiment and then report back our findings.
My goal is to make this kit cost effective and easy to deploy.
However, if there is something specific that you would like to see us do (or not do), please post it up.

also, it looks like we will try the setup utilizing the stock intercooler initially, it will be interesting to see how well the stock intercooler can cool the intake charge from a turbo setup...

2002 C32 Stock at the moment
Well, it isn't going to be a super PITA. We are going to keep the supercharger in place, so there will be no need for a custom / C320 intake manifold.
Imagine a gutted supercharger with twin turbos. We will also leave the stock IC in place, and possibly cool the charge twice.
Erick is going to manage the turbo manifolds.
I'm going to head up the Intercooler fitment and tubing placement.
As of now, I don't think we will need a new MAP sensor or IAT sensor. If we can get 18 - 20 PSI without spinning the SC, then we should be set. The ECU won't know the supercharger isn't providing the boost, nor does it matter, as long as the right amount of boost is present. The SC clutch will need to stay in place or else the tranny won't allow the car to shift.

A trick I used on one of my twin turbo Subaru's to remove the Factory boost control was to use a resistor across the disconnected terminals. You can fool the ECU into thinking the SC clutch is still there by using a large wire wound resistor with the same resistance value as the clutch, thus allowing the removal of the belt from the SC or the complete removal of the SC would be even better. IMHO a gutted SC could cause turbulence in the intake.
The Nissan GTR uses twin GT28's and at 2.6L would be a good place to start looking at turbo's

Eric - You guys thinking of using the "Disco Potato"?
It would be more work but I think you guys might be better served using the Intake Manifold from a C320.

moving the throttle body to front, this is a popular mod for the WRX with front mount intercooler as it shortens the intake (Less Turbo Lag)
Sell the AMG Supercharger should pay for the C320 manifold

Guys this is an awesome project good luck, the theory behind this is quite sound. I have had 6 turbocharged cars everyone of them modified in some way. A well setup turbo will make awesome midrange power.
A trick I used on one of my twin turbo Subaru's to remove the Factory boost control was to use a resistor across the disconnected terminals. You can fool the ECU into thinking the SC clutch is still there by using a large wire wound resistor with the same resistance value as the clutch, thus allowing the removal of the belt from the SC or the complete removal of the SC would be even better.

I agree that the car should have good mid range power.
Keep the ideas coming!
