I am going to rebuild my 88, mazda rx7 gtu and want to turbo charge it. What kind of turbo should i go with, any ideas?

 

How much power do you want? What's your budget?

 

GT42R, nothing less!

 

This is way too vague of a question... and it is not really that easy. Do some searches and you'll find a lot of information. Or at least give us some goals to work with.

 

GT55!! dont skimp!

 

well I would like to brake 200MPH.

 

Why set your goals so low?

 

I was also wondering how much stock horsepower they came with. I have 2 88 gtu's, the one I just bought the previous owner polished the intake and unrestricted the air intake a little so I don't know what I am running.

 

well what could get out of it? bcool.

 

250mph easy with a simple T04B upgrade

 

Well the polished intake does yeild a good gain, better airflow dynamics, that can yeild up to 70HP

 

that's pretty quick. how much RPM could i get up to if i ported the engine.

 

NOOOOOOOOOOB!

200 mph, you've got to be joking me... I mean come on. If this is your first turbo'd car your goals are waaaaaaaaaay too high. The fact that the car wont even go 200 on the stock tranny is going to be a problem. So uh... good luck with that.

 

Is any of this thread actually serious?

 

^ Rob you bastard, i wanted to play some more, anyways. Your transmission will be gear limited at around 150-160 i belive anyways. I could show you a video of a 3rd gen speed test car out in the salt flats doing 215 when things went into the air. You're better off just researching into a J-spec motor.

 

yea he did say MPH not HP and 200MPH on a stock tranny, not gonna happen

 

nevermind.
