i have a series 5 turbo engine

im about to purchase a turbo

but i dont know what is better for me

my mods so far are

Street port

1600 cc sec

550cc pri

electric water pump

turbonetics t04e

haltech e6x



my car is intended for drag racing and some autocross

so i dont know which turbo will be better for me

and what a/r too becose i dont know about what a/r will be better



and i forgot that all is set up in a 79 rx7



PD forgive me if i dont write correctly inglish , im not to good at it

 

Making a car that is good for autocross AND drag racing can be hard because autocross cars need low and mid range power and fast turbo spool up, and a drag car doesn't care much about spool up and is mainly concerned with top end power only.



If you are picking from 62-1 or T66, I would pick the 62-1 because it will spool up better than the T66. 1.00 A/R divided exhaust with a P trim wheel.



What's wrong with your T04E anyhow? Not enough top end for drag racing?

I ran the 62-1 and was very pleased. Has good low end power, not too laggy, and has great top end too. Very good for various driving. Mine was 1.0 on the hotside, .7 comp, P trim, and 4 inch inlet.

so i dont have to push so hard the turbo like i do whit the t04e

 

You can expect 400-425rwhp easily with that turbo. Turn the boost up a little more and you'd be 450 or higher pretty quick.

450-500 rear wheel hp? 450-500 rwhp @ 15 psi + good at autox just don't add up.



Any turbo that will give you 450-500 rwhp at 15 psi is going to SUCK at autocrossing.



If you mean 450-500 at the ENGINE, that's only about 350-400 rwhp which would be good for the 62-1 (or the T04E maybe or the T66 or several others)
