At the very least 600hp, together with a lightweight hydro-formed chassis, would make the MKV Supra Turbo competitive with the C6 Z06. Imho, there's nothing wrong with the current structure/geometry of the jza80's double-wishbone suspension; add a set of Moton/Penske/Ohlin coilovers (perhaps as a factory option, like the fluid definition of a 'stock' Viper ACR), and it's more than sufficient. Niceties aside, and all else being equal/similar (weight, rubber, etc.), horsepower wins races...

N/A is better horsepower then turbo, no turbo lag

Yes, but who races in the lag portion of the rpm band? Answer: Nobody, ever.

have fun always running your turbo engine at 7k goodluck with a long track and reliability.

Hello! Newb here, to chime in... In stock form, i'd be inclined to give the edge to the SVT in the 1/4 mile, but it could also be a driver's race. Being RWD, both the Supra and the Cobra probably fall back to the VR4 from a dig, but the AWD drivetrain costs a VR4 about a 30% HP loss to the wheels from a substantial roll. This is why they tend to trap lower IMO, and I feel in stock form, the VR4 would be the slowest of the 3. (3,800 lbs doesn't help much)

I'd give the edge to the MKIV from a roll, and total top end, over the stock Cobra. Both the MKIV and the SVT take to mod's greedily. The SVT is prolly cheaper to mod though. It can go either way...add a big single and a few other goodies to an MKIV, and it may not win in the 1/4, (without a shot of NOS to spool it) but it will rape most SVT's from a roll, and way up top.

As for the new ZO6...that's a bad ass car. I believe the magz ran a mid 11 with it in stock form, with the WHP being like 459. Stock on stock, The Z06 wins. Modded, it depends. Unless the z06 has LF heads, and either a SC or turbo/s, I can't see it beating a big single MKIV up top. Keep in mind, the displacement factor too....Those who bitch about the Supra being a turbo, and the Z06 being NA, it SHOULDN'T be a legit gripe, being as the Supra has less displacement to start with.

I'll end by saying: They are all neat cars, and I am not biased. I like all fast cars, and to each indivdual owner, their car is unique for it's own reasons. Be safe, and keep the great posts/information coming!

dont confuse mine and pw's convo about na to turbo power, we werent saying that cause the supra has a turbo its unfair to compare i mean look at displacement 3.0-7.0 obvious difference

Yes, and when an APU MkIV Supra runs 29+psi of boost, it's a virtual 9.0+L. I agree the comparison is unfair.

This is a valid point, I guess. But I often hear people complain (usually NA domestic guys) that forced induction or "power adders" are unfair advantages when comparing a NA & a blown car of lesser displacement. To me, fast is fast...period! Doesn't really matter how you get there, just how fast you get there.

Whiners... ;)

Agreed!
