Which Engine to use as a base? Hi Guys,
Firstly thanks for an excellent site.
I am about to embark on a new project after years of tuning JDM MKIV Supras.
I am intending to install either an LS1 or LS6 into a FD3 RX7.
My question is which engine should I buy based upon wanting approx 450 bhp. Main criteria are cost then reliability. Is it cheaper to buy an LS1, add some heads and a cam, or start with the lS6 as the base or even an LS2?. The car will be primarily used for circuit days, so reliability is a big issue to me.
I know very little of these engines at present guys so please be gentle with me.
TIA

I just spun a rod bearing and went looking myself. Best deal I found was a complete 2001 Vette crate motor from MIZFIT Motorsports for $3750. The bitch even came with a water pump.Add a cam and the boltons and you'll be close.

Thanks guys, I am in the UK so restricted to looking on ebay at the prices, and the LS1 certainly seems cheaper.
My train of thought is leaning towards:
LS1
AFR 205cc Heads
Comps Cams 224/228
Uprgrade the valve train
Fast inlet manifold C/W 90mm TB
85mm MAF
Does that all sound reasonable?

depends if u want to tear it open or not. i got a deal on a '98 and did a complete rebuild w/ aftermarket and ls6/2 parts. if u jus want to buy a pullout and drop it in the car. u should find something '01+.
