Thank you for the link.



As you might have guessed, you've posted on a forum full of 'Supra biggots' (speaking primarily for myself, if not more). I hope you don't mind if I provide some honest feedback from myself personally on that v8 Supra project documented on the other forum:

1. Several Mkiv Supras are in the low 8s (full weight!), and even a few in the 7s using the mighty inline-six 2jz-gte.
2. The 2jz-gte's in these low 8s Mkiv Supras typically put out 1400rwhp+
3. I absolutely do not understand why there's any appeal at all to "600hp without the help of boost" Exactly what does "without the help of boost" buy you, other than the excess weight and poor fuel efficiency of a much bigger, inherently unbalanced v8 block to lug around?
4. With only 900hp (600 motor + 300 nos = 900 total), even gutted and back-halved the way it is, I doubt that v8 Mkiv will do better than high 7s.

So given those points, I find myself struggling to determine a point to that whole project. To be totally honest with you, I feel it would be far more appropriate to put a 2jz-gte into a 'vette or 'stang or viper chassis. Really!

Please explain...

i'm not the owner of this car but as they stated on the forum i think the reason for goin the V8 way was because of cost which i totally understand since this was done basically in someones backyard. also the builder has experience with other V8 engines so it was just the easier way to go.

I appreciate the additional info, but to me it still doesn't make sense. A bone-stock 2jz-gte bottom end is good for 1000hp. Why not just stick with that, and not worry about needing any engine internals expertise, or the expense of aftermarket parts (even v8 aftermarket race internals aren't cheap - nothing like a Toyota engine bone-stock parts anyway)?

I'd have to agree with the 2JZ being more than ample for drag racing.

If I was to do an aggressive weight reduction campaign, I think I'd prefer a NA V8 on a road course, though.

Are you sure a v8 would weigh less than a 3L inline 6 with a 61mm single turbo?
