i dunno how to search this type of thing.

anyway, i have a 1991 RX-7 N/A and plan to do some of the basic upgrades with the stock ports.

so:

- cone filter
- air/fuel controller
- crane cams ingnition
- RB cat back (DONE)
- Bonez SUperflo (DONE)
- T2 tranny with lightweight flywheel (DONE)

anyone with the same (or close to) planned mods as me that has gone through a dyno?

i wanna dyno my car after alls put in.....i just wanna get an idea of what i should expect as an increase.

Tessai

any mods?

150rwhp is pretty easy to achieve for an NA.
Strait exhaust.
Remove A/C and PS
SAFC-II
Cold air intake
You should be able to hit 150rwhp with just that on a stock NA, as long as it's in good condition. You could also remove the air pump and all the emissions stuff (for ease sake, this doesn't really give you more hp) and remove your 5th and 6th port sleeves (gives you better top end, but kills the low).

sorry i forgot to point out....a fully smog legal 150rwhp.......i have the superflo inplace

Parastie

That still shouldn't be to hard, just have to tune it. You might need a street port.

Doh, forgot to say.. car is completely stock. Since then I've replaced plugs and filters, it seems to be running a bit better now, but I doubt its got much more HP.
