1990 turbo rx7.



Getting engine rebuilt, should i just go mild port on intake and exhaust.or just port the intake and leave the exhaust port as is?I been reading these porting threads. dont plan on pushing engine past 13psi which would be around 350-400rwhp for everyday use/drifting and 17psi whatever else. Turbo is a TS04 with .84/ar divided and .70 intake comp side with greddy type r wastegate. I was hoping of getting a really solid tourqe band and turbo response.i have proper mods for this turbo setup.







Thanks

I would recommend either the 60-1 or TO4E "60" for better low boost efficiency.

The TS04 runs similar numbers, but it's efficiency is for higher boost (15+).



I think this is in the wrong section.

NO this is the right section... I had a friend with a ts04. it seemed to make good power for a 1/4 mile run but it didn't do very well on autocross. for drifting you want a turbo that will spool up quickly and hold a good power curve high into the rev range, like about red line. it all depends on how you like driving your car..If your dead set on this turbo find out if you can get it in B.B. that should help you.

I got the turbo already, for a good price, used. I"ll experiment with it and see how i like it, will Keep it at 13 psi for a safe start. What kind of porting is recommended?



Thanks

My friend had a large street port but. what you want depends on you...you can run stock ports..but depending on your budget go with a mild street port or a little bigger. you have so many options when it comes to porting.
