Hello all. Ive been looking to buy a FD RX7 with an LS1 coversion done. I found one fairly local to me that already has the swap done with what looks to be a decent stroker setup. Here's the basics of the engine:

HSC Built 383ci LSX V8
4" Eagle crank
Eagle rods
Ross Pistons (11:1 CR)
Race bearings
AFR 225 heads with spring upgrade
DRE Rev Kit - Hydraulic roller
Comp Cams Custom Grind
ARP Head studs
Cometic Gaskets
LS6 Intake
Ported GM Throttle Body
ASP Underdrive Crank pulley

It also has full length headers and a 3.5" single exhaust all the way out.

They have rwhp estimates at 475, but due to the shitty tires on it (225/50/16 crap radials) it was spinning on the dyno.

Going of that basic list above, does their estimate sound about right? Also, I do not have the cam specs as they aren't listed. I can also imagine that a FAST 90/90 setup would be a lot more suitable than the LS6 intake as well.

Thanks

I would say between 475 and 500 to the wheels. its going to depend a lot on how agressive the cam is.

Tell someone to strap it on the dyno correctly, no reason it should be spinning on the dyno IMO.

Can make a guess on power either, thats just as important as motor size.

Thats what I was thinking, especially at that power level. Either strap it down better and/or sit some people in the hatch.

Thanks for the replys though.
