Man...I was bored here at work and Rx7cms and I are gonna hopefully be building a bracket racer 1st gen shortly all motor so I got to looking at stuff online and I came up w/ the ultimate(in my mind) 13B NA setup:



RB aluminum housings w/ Peripheal port = $5500 for the set.

Carbon 3mm race apex seals = $33 each

Lightweight racing rotors = $1200 each

Fully balance w/ proper counterweights,etc = $500

Racing stationary gears and bearings = $400

dellortor sidedraft and BIGASS carb https://www.nopistons.com/forums/pub...IR#>/smile.png

All for around $9K in the motor alone that would push 310RWHP @ 9KRPM



THAT would be awesome..the best part about that motor is that w/ the AL components, I'd save 57lbs in weight from the block alone, and w/ a 1st gen stripped...it'd probably only weigh like 1800 w/ driver! 11s would so be possibly w/ a strong driveline and slicks!

I dig the RB aluminum housings, but man the price is out there.

Yea...1200 for the front & rear and 1550 for the intermediates...but damn man..you know its worth it! PP and AL https://www.nopistons.com/forums/pub...IR#>/boink.gif





imagine that motor setup w/ a 100+shot of NOS!

NOS and change that to a weber 48 ida then you're talking. :yum:

how about the factory slide throttle fuel injection setup?

That would work too.275rwhp NAJust remember to use S5 T2 housings.They are way better for all motor than NA ones.

Damn thats a big tag for 310rwhp. Would be fun though :bigok: Sooo many toyz, not enough $$$.

I know what thats like. https://www.nopistons.com/forums/pub...O_DIR#>/11.gif

You can get a 48 ida carb ported to 62 mm, that would be my choice of induction.

Prolly put out 10mpg but the power. :yum: https://www.nopistons.com/forums/pub...#>/BURNOUT.gif

10mpg.. that would suck.. but you're right 310 from an n/a would be great. :bigthumg:

just make it a weekend racer.Imagine the looks on peoples faces when they get hauled by a NA rx. :twisted:

Yea really.. once I fix up the FD.. time to go all out with the n/a.. https://www.nopistons.com/forums/pub...#>/biggrin.png

How reliable, or lack of reliability would a 310hp N/A be. Would it be as reliable as a 13b with turbo putting out the same horse?

basically the 310-320hp na's are what they ran in the gto class starting in 83, you could prolly get 48hours at full throttle out of it



mike

Yea...don't look at having a 310HP NA motor lasting much past 35K miles of mild driving,lol...



a 310HP turbo would be more reliable...

i think thats right, the turbo would last more miles on the street but the na would last longer racing.
