ah, thanks michel.....

 

You and John have to come back down and come for a ride with me....my turbo has the same compressor as the A-spec kit (88mm). I'm still in the 10's a/f wise but she's a rocket. Stupid fast, just the way I like it :-)

Michel

 

wow, you mean next time i come down your car will actually be running like it should!!! hahaha, i'll do that next time i'm home. i need a new clutch and might switch manifolds and stuff too.... we'll see,



oh by the way, did you say rolo up here in orlando is a pretty good tuner? maybe i'll get my car dynoed there when i'm done fixing it....

 

There are two dynos in Naples that we can use. Yes, he's a great tuner though. Compact is in the process of making a mild steel fully divided manifold. You could always get that ceramic coated inside and out...



Yeah she's pretty healthy at the moment. I pulled a 996 twin turbo like she was sitting still today. My front seal is apparently leaking though so that's being changed out on Saturday. It never ends....

 

To Zero R

What is the size of turbine housing of turbo GT40R in your picture?

Is it 0.95 or 1.06AR?

I will put this turbo in my skyline gtr so which AR you recommend for rb26 (2600CC). My target power is over 600Whp with new piston, con rod and 272cam 10.8 lift at 1.6K boost.



thank you

 

It is .95 and I may have a better turbo for your skyline, I will put something together and get back to you, I'm actually working on a twin 35R RB30 setup right now. I may be able to help you with your skyline project.

So which turbo you recommend to my skyline Sean?

What is your target WHP in rb30 twin GT35? (I guess 1200 hp ..Cool) and how you deal with the gearbox and front drive shaft? even holinger sequential may have problem at that level and hks front drive shaft will last for less than 5 drag run

How about your GT40r on 13b-rew, Have you test run turbo already?

Why you select .95 AR instead of 1.06 and what about exhaust temp?



Thanks Sean

 

On a GTR you can get 450-500 on stock turbines, so this turbine should get you to 600 easy. Gtr's with cam's and stock bottom end and t04r/ t78 size turbine get anywhere from 700-900. With all the supporting mod's of course.

 

Sorry for the late reply, I had a Idea I wanted to chase down for you but haven't had the time, the 40R with the .95 should be OK, my goals on the RB30 are not that lofty it is attainable but we'll see it all depends on the customer, as for going with the .95 on the kits, I sell both the .95 and 1.06 it's up to the customer really.

sorry, slightly off topic, but where does that "Performance Calculator Mazda RX7" computer program come from? (I searched)
