400-450hp will be my goal

should be easily obtainable without the silly gas. should certainly surprise some Viper/Vette/Camero drivers too.

just get yourself some 3mm apex seals. call m2 they got some kick *** 3rd gens. even if mike johnson doesnt build them anymore. remember a 13b can be pulled with two 2x4s and two people. you dont need a cherry picker to pull the engine. i use ta have one.

You're missing the point. I don't want to have to pull my engine and rebuilt it. And I want torque!

I would say go LS1 cause its so different then everybody else. The 20B three rotor is pretty tight too, but thats more work i thought.
OH yeah what about dropn in a LS6 motor and a Lingenfelter twin turbo setup. I dont care if its to much power. I think anyperson who loves cars would give you made props cause its the best of both worlds. Import+domestic+boost=pretty cool?

I don't think there's enough room under the hood for a TT setup. As it is the hood clearance on the front of the engine is tight. And besides, those upgrades are very expensive.

Yeah but it would be cool, right? Then just go s/c with a phat *** blower stickn out the hood. Im sure people will wonder whats goin on when they see a RX-7 like that. Yeah i just decided i would do the s/c.
Think anyone could do a photoshop pic of that???

LS1 = high compression which means not boost friendly. The reason they can make 350-400 HP N/A is the high compression, 93 octane gas, great flowing heads, intake and exhaust. Correct me if I am wrong, but isn't the C5 and Z06 motors in the 11.X:1 compression ratio range? High peak temperatures without forced induction.

I don't remember the compression ratios for the LS6 or LS1. But I do know that they can go FI.

Yeah, I have seen and heard of several that have a super on them. I would think intercooling is almost a necessity on a stock compression LS1 or LS6 when using pump gas. Good luck on your project, onikageka.

How about after the LS1 goes in you change out the headlights for the non-pop up kit. Then maybe a widebody rear end kit with the old fender cut away so you can run a wider rear rim and tire. After all your going to need the traction.

With proper gearing I'll have plenty of traction. I plan to use the 99 Spec RX7 rims with are 255/40/17 in the rear I believe. They will be wide enough. Hinson's car ran 11.4 on 245 street tires. And he has 400rwhp.

The widebody rear kits just look so much better. Especially if its the kits where it flares out like Porsche fenders instead of just those add on pieces that go over the top of the fender.
