ok, I'm sure most of u guys have beaten the subject 2 death here, and I read all 4 pages of posts in this section, and didn't see anything that helped me specifically. so here goes.............and I apoligize if I sound dumb!!!!!!!!!

I am planning the purchase of a turbo II at the end of august/ beginning of september, I have been around a while on the 2nd gen forum(new to this one) and have read quite a bit about the TII, but concentrated on the na, since that's what I owned. It's gone now, and I admittedly have lofty goals for my next rx7, lofty in the way of close to 400 horsepower. Can it be done on stock ports, I'm afraid it can't, but tell me anyway. So my question is..........,proper fuel mods, and tuning assumed, what'll it take??? who has done it(stock ports or not), and am I being realistic? I don't mind spending some dough here, and I do have a good parts hookup. I'll be doing most, if not all of the install work myself (with help from some more experienced friends). and time is not an issue, I have all winter to play with the car while I drive my beater.

so gimme an idea of what I'm undertaking here... any help is appreciated!

 

I would go big. The bigger the turbo the better if your trying to make 400 wheel horsepower on pump fuel. T04S would be my first suggestion. Something Big T-66 etc.

 

Or How about size it down to reduce lag and get a TO4E. W/ a street port and a TO4E will bring you close to 400RWHP. Or even 60-1. Both are cheap and have proven to make 400RWHP.

A member by the name of BDC has a TII w/ 60-1(A/R 0.96 P-trim turbine) and street port, makes 424RWHP with pump gas running 15psi.

Good luck!

 

or if your worried about lag buy the GT3540. Its a Garrett Dual ball bearing turbo that spools fast but still will make well over 400 RWHP on pump gas. That was my choice. I was concerned more about response than making sure I went over 400 hp at the wheels. It just happened that i made over 400 with a stock motor. A Ported motor would garrentee 400 rwhp.

 

is there a gt3540 kit for the fc??? I know your results are from experience with the FD, can I expect similar results with a 2nd gen? I had considered this upgrade when I was looking at a 3rd gen, and it seems to have alot of advantages

 

A lot of those kits are too funky and expensive. More for the FD guys. You can make a lot of power with pretty basic, large turbos, on a 13B.

I'm sure you can do 400whp with a T62-1, even on stock ports. Just might take you 20 psi.

A T-66 is too big for the street, AFAIK.

Why does this need to be on stock ports?

If I was planning a big turbo upgrade, I would rebuild the engine with a large streetport, anyway.

 

I agree with Evil, You can achieve 400 hp easier with a ported motor. You will also have more choices for streetable turbos that will make the power. There is a place making a GT3540 kit for the FC. I will PM you the info.

 

thanks guys, I figured that if I could make the horsepower I want on stock ports, then when the engine goes, I can then do the porting. Ideally, i could get a car with a **** engine for cheap, throw in a rebuild(large streetport) and go from there. But if I can get a car that runs strong, why not do the upgrades on it... they'll all transfer over to the rebuild in the end anyway
