Howdy Folks -

I've been stockpiling the parts for a high end JZ2 buildup - Carillo rods, JUN pistons, ARP fasteners, polished crank, new JZ2 bottom end, topping it off with Ferrea valve components (on "street ported" heads) - Whew!

This motor would (should) be pretty stout - probably keep the T04R setup, and also go with some 264 cams. OK, this will obviously produce some great numbers when tuned, and be able to handle some serious boost with the right gas. But it will still be a little sluggish on the bottom end, and have special fuel requirements for big numbers (though my current setup makes over 500RWHP on pump gas so I don't know how much more I'm looking for :D )

So....I was wondering what might gain me some decent low end, still make big numbers, but with improved area-under-curve (vs. a JZ2) - and respond well to forced induction, *especially* considering it's capabilities on pump gas. And finally, I was thinking what motor would still have a "tie" to the Supra lineage.

It seems like a Lexus 32v V8, either the 4.0 or newer 4.3L would be very interesting. I've seen on a couple of sites where with performance parts, they're pushing 400HP *NA* - you figure lowering the CR a little, and add some boost it would be an interesting combo. Of course, you would need some exotic aftermarket engine management solution (Motec?). The motor is all aluminum, so it would be at least as light as the JZ2 - but on the tradeoffs, it would likely not be as capable of high levels of boost (?)

I'm aware that HKS has built a Supra based (tube) drag car using a Lexus V8 and twin turbos cranking out some *insane* HP levels, but at (I'm sure) equally insane costs too :eek:

Just thinking about alternatives - obviously I would need to work with a pretty knowledgable builder - someone with capabilities beyind just bolting on a turbo kit. I might contact Swift Racing who does Lexus upgrades including a number of boosted applications. And it would really be a one-of-a-kind upgrade.

Thanks for any opinions, insight and general nay-saying!
