my car is a 1981 rx7 with 12a(all stock).i recently bought a used manifold for weber IDA carb with a weber 48IDA fitted on.i'm thinking of having it fitted,remove the cat and use a straight pipe from header to muffler.i also want to buy a performance pacesetter or RB header and muffler.what would be the estimated horsepower for my application?

should i need a better fuel pump?

B.T.W.my car does not got an air-pump anymore.

well you might gain an extra 20-30 hp from the headers, carb, and manifold. and you will need an upgraded fuel pump.

PACESETTER IS GARBAGE!

Spend the extra cash go with RacingBeat..you wont regret it!

well,what pump you insisted me of using so it can afford my future plans(13bt)

get the holley blue pump its only 80$ and comes with a fpr

should the holley blue pump be enough if i ever convert to 13b turbo

no it wont be good for a turbo motor.

Sorrow_RPMWarz,,, how many pounds of pressure do you have coming into the carb???

13b1stgen,,,, the blue holley pump comes with a regulator??? Where did you buy it from??? Summit???

:flush:

i got the pump from Murrays Speed & Customs which is a Holley dist. here in Miami.

shall a stock TII fuel pump fit to my 1981-rx7?

if yes,what modifications should be needed?
