Rx7 turbo
Hello, I have a 1992 miata na and I'm looking to turbo it. I came across a pretty good deal, which is a s4 t2 turbo off of an 87 rx7. My question is is there any manifold I can buy that will straight bolt on to this, or will I have to have a shop fab up a manifold and downpipe. I'm new to miatas and to turboing(not to supercharging though) any answer would help thanks!

What's an s4?
Turbos are cheap. Pick one because it is the right one for the powerband of the engine and has common flanges and not weird ones. |

I want to try and keep it under 2k. That turbo is going for 100 bucks, which makes room for the megasquirt.

S4 is the '86-88 RX-7. The turbo was only offered in '87 and '88 (as S4 models). S5 was '89-'91.
They are all 2nd gen RX7s. The S5 was a minor model change. The 2nd gen rx7 turbos are really wonky with weird flanges and sizing. Your life will be much easier if you chose a much more conmon turbo with a much more common inlet and outlet flange. |
Welcome, ScrapinMX5. Check out the Miata Gallery and post up some pics!

2k is going to be pretty tight. You're talking about having the turbo, exhaust, i/c, i/c pipes, BOV, boost gauge, wideband, 1.8L, Torsen, etc. all fit into $1k.
Sure, you can turbo your car for that much, but you will spend more money and have much more down time in the long run than if you just save up and buy a good kit from the start. |

Forget shanghai, save for MK Turbo setup. Better for similar money.

I would't say everything about my setup is better. The turbo is definitely a better match for the miata, and mine comes with a full 3" exhaust. The Begi cast manifold I will say is better then what I offer.

You still need intercooler and piping, but that's just a cheap ebay kit away from being all you need there.

I'm really liking your setup for that price. Does it come with everything I would need besides bigger injectors, ECU, and oil pan tap?
