I have a 93 RX-7, and I am thinkin i would like to go single.. I am wondering what I would need in full, and what the best setup without to much lag. I also want to be as cost affective as possible. any ideas would be great.. my mods are down below. Thanks

bigger injectors is a good start. But you can reach that hp goal o the twins

Mfanto

ya but im allways having boost issues. I mean its nothing serious, but there is allways something up with them. I think with a single It would simplify, and be less headache. am I wrong to think this?

if your goal is to reach 350 hp with a spool up turbo i will recomended the rx-6 apex turbine kit spool up very fast, you car reach about 400hp with this kit,and a lot of pain in the a... will go away replacing the tt factory units.

Thats kinda what im thinking. so if i buy a kit.. will it come with everything I need. I dont wanna be chasing parts

Depends on your current mods. If youve already got new injectors ( i see you have an aftermarket pump and a pfc) then I believe you simply need a larger intercooler to support it. There was a post a while back asking if a SMIC could support a single turbo, I'd look that up if you dont want to get a larger IC. If you dont have injectors then I'd suggest rotary extreme's fuel system as its currently on sale 100 under its normal price (check the monthly special section).

Good luck, I wish I could go single >_<

I'd say go with a T04S with the following specs... a 60-1 wheel in the T04S cover with a P trim exhaust and a 1.00 or 0.84 divided turbine housing. This setup will do 350 rwhp easily at a low-ish boost of around 12 PSI or so.

The Apexi RX-6 is another good pick for your power requirements, but the only reason I'd avoid it is because that turbo may/may not be rebuildable... and where the heck would you get parts? I don't know.

P.S. If you read my little tuning document, the first couple pages deal with some of the issues with building up your single turbo car....

i agree. i to4s is what i have.

I talked to RX-7store.net and they said the best turbo to have for me would be the GT35R. I have heard of this turbo, does anyone have any comments on it? I will also need a new fuel rail, FMIC, and im wondering if i should upgrade my radiator? What do you guys think?

keep your twins and dollars if you only want 350

Mfanto

I want 350 on low boost, and 400+ on high boost
