I just recently got a 86 rx7.

and im planing on building it to about 400 hp.

iv always worked on 240's because thats what i use to have so im kinda new to the whole rotary thing.i

was wanting to know what should i do internaly wise, to prepare it for this amount of power.

any input would be great. thanks

You will get nowhere without a turbo.



That is the only input I will give since you obviously didn't search.

^^

Whats with the search nazi - does this look like the club?





Its a long winded conversation to tell you what to do, but for starters, you have an '86 which isn't turbo. You'll want to pick up a T2 engine and go through the swap. You'll need an engine, driveline, harness, ecu, etc.



To get 400hp, before you put the t2 engine in you'll want to rebuild it, get a nice street port job on it. You'll need standalone and a decent turbo (t4). For internals, you can just run stock seals honestly. I'd bump up to get the FD corner seals (or go solid) and springs.



The S4 motor will take 400whp without causing too many issues -



Have DEEP pockets, thats the best advice...
