Whoa old thread.

I have been thinking about trying twin 35's on my 3s when the 3.6L goes in. They seem to compare to 16G's on the flow maps so I'm not sure there would be any gains... I have heard great stuff about their inducers though.

I think 35 are way bigger then 16gs.

HAve you heard good things or bad things about what inducer?

I went away from the Holset. Here is what I'm putting on the 3.8 stroker.

These are twin Borg Warner S-200. They have split turbine housings and should spool up nicely with the 3.8L

The last graph shows boost levels for 1200HP on 3.8L with the twin S-200's

Wouldn't you run the graph with 1.9L?

Typically, yes, but the graph is from squirrel performance's virtual calculator, and they allow you to select the number of turbos used. So it does represent 3.8L with 2 turbos. I don't think I would ever run 42PSI of boost, but Its nice to know that the turbos will push it out to 9000 RPM, if I ever wanted to.

How do you pipe twins that are split housings? Is there no negatives in doing that?

Oh alright. That calculator is pretty sweet. Can you upload a map if they don't have it?

That was my second question. ~43psi of boost sounds like FUN!

I have the HX40 with a the bullseye housing, what sucks is I found out the HX40 wasn't from a Cummins diesel so it dosn't have the same turbine wheel, instead it has a larger one so now I'm stuck getting a new turbine wheel and getting it replaced and balanced which isn't cheap

The most common modifications are (but not limited to): - Huge exhaust that serves no purpose but to make the car louder - Large spoiler on the back that looks like something Boeing made for the 747 - Lots of after-market company stickers they don't have parts from, but must be cool - Expensive rims that usually cost more than the car itself - Body kit to make the car appear lower, usually accented with chicken wire - Clear tail lights and corner signals - A "performance intake"- a tube that feeds cold air to their engine usually located in areas of excessive heat (behind or on top of the engine) - Most of these riced cars (a.k.a. rice rockets or rice burners) are imports; Honda Civics, Accords, Integras, CRXs, RSXs, Del Sols Mitsubishi Eclipses, Lancers, Subaru Imprezas, however there are some domestics such as Chevrolet Caviliers, Dodge Neons, Ford Focus; small, slow, economy cars designed specifically to go slow. Please note that some 3000gt's Supras, Skylines, WRX's and other higher performance imports are designed to go fast, and are therefore not always considered rice, but it really depends on the severity of the case.
