hey guys

this is my first post on here, and am looking for some advise. i just picked up a 86 s4 fc rx7 non turbo, but i belive the it was turbo in the first place as there is the turbo bonnet and timer fitted.

firstly is there a way to tell from the out side of the block its is a turbo block. im sorry if i ask dumb questions however it is my first rotor and there a bit strange to me.

secondly: im not asking for alot but i want 300bhp at the rear. as im gonna use it for local drags and burn out comps. would a twin turbo or a single big turbo do the job better. i would like to try and keep it road regestered aswell.

any help would be great and i look fwd to lots of rotor fun in the near future

i have really like the feel of a single big turbo car when it hits full boost

 

I think you and me may be in the boat, we need more posts to be able to actually ask questions of the guru's.

 

Ok... I don't know of a way from telling if its a turbo or non turbo block by the block itself. I can tell by the exhaust and intake manifolds though. On top of the manifold, is there two screws where a top mount intercooler used to bolt to? If so, thats a sign of a turbo'd block.

Another way is to check the exhaust manifold. Does it go straight from the block to the catalytic converters?

In all honesty I'm 99% sure its problem just a non turbo car with a turbo hood. If you post pictures of the engine bay, we can tell immediately.

300 horse power to the rear wheels can be done with a turbo RX-7. From a non turbo RX-7, you can do everything under the sun to the car and you will only get 250 horsepower to the wheels, maximum. This has been a big debate for years. If you're looking for a real drag car, you won't get it from a non-turbo RX-7, unless you're running in classes.

 

i know this isnt much help, but what your looking for is very realistic, i see it done all the time, with the right size turbo it would be easy. I would say a t-70 plus

 

hey guys thanks for the info. im out offshore atm so ill send some pic through when i get home in a few weeks.

but could anybody tell me the dif between the 2 blocks if it is a non turbo block could i put a t06 turbo and complete engine pc on it and if i did would damage could i do if its a non turbo block.

i know these are stupid questions but like i said before i an not experanced in playing with roterys thats why im asking these silly questions now theres only one way to learn more and that it to ask other people that have been there and done that.

i am also thinking of upping the size of injectors and fuel pump (bosch 044). to be able to get 300bhp at the wheels what size injectors would be a good choice...

thanks again guy for your info.

 

There is a difference between turbo and non turbo engines. Non turbo engines have 6 ports, turbo engines have 4 ports. Although its possible to turbo a 6 port, and it has been done, its generally accepted that if you want a turbo'd RX-7, you drop a turbo engine and drivetrain into it. Get some more posts then check out the second generation (FC) section, as well as the performance modifications section. Good luck, and send some pics when you can.

 

ok kool ill look at getting myself a frount cut import. with a 13bt in it. what is the standed power out put of these does anybody know, and what would be best starting place to get more hp out of it

would i go for a bigger turbo and better pc and would i also need to go for new fuel pump and injectors. if so could you please advise what would be the best way to go to be able to achive my 300 at the wheels im looking for.

There were two different power outputs for the second generation turbo engines. One was around 185hp, the other a little under 200hp. I think a fatter turbo with a standalone, as well as an upgraded fuel system and front mount intercooler would be great. If you rebuild the engine, look into porting. I'm not much help with turbo engines as I don't have much experience with them, so just get your 5 posts and head to the upgrades sections.
