I would not think the weight distribution would be thrown off too much at all. The engine from the pictures does not appear to be grossly forward in the engine bay.

The #'s I found..feel free to correct me if you find something that says otherwise. 2JZ-GTE + 6 speed trans = 750 pounds dry. Whats a BP weight with trans?

Engine and tranny are 450 lbs according to a random thread I found on M.net

Thought 750 seemed a little much but what I found said motor was 595 with tranny put it at 750. Ill keep looking.

Are we talking about the 2JZ or the BP?

I was reading 450-500lbs for the BP with tranny, but the resluts were varying. There's so much damn misinformation

We (at-least I) were/was talking about the 2JZ.

I believe the obvious is the 2jz.

as soon as i saw this i was like :cjerk:. i've wanted to do this for a while now. i'm actually a member on supraforums cus i'm trying to learn more about the 2jz. about the weight: wouldn't it be the same as doing a v8 swap? just beef up the brakes, springs, struts, and swaybars and it should handle pretty good right?:dunno:

It depends on your definition of good handling

With 300 extra pounds on the front wheels it would handle like total crap compared to stock, but probably still better than most cars, haha

MartinezA92 11-29-2009 05:23 PM

I remember when I did an engine swap on my car, I had the BP and trans together...I really don't see that thing weighing 500 pounds...
I guess the scale doesn't lie.

i mean people swap big v8's in miatas and get good times on road racing courses so it cant be all that different can it?

LS1 = 390lbs. :fawk:

It's cool, I'd drool if I saw it in person and beg for a ride, but...

...unless it's going to be north of 500 hp with the traction to plant it it's pointless. An SR weighs a lot less. Flamesuit on.

at least you didn't say an RB swap....

Actually; I've seen more than 1 with over 900 hp down here (not in a Miata though).

the Supras are very popular here. More than 3 doing low 10s at the local dragstrip


Curious about the weight. I'll check with my local mechanic tomorrow.

Hi i would like to start out by saying the car you guys are seeing on supra forums is mine. This is a 92 miata that i have had for 5 years now. This is a 95 supra NA motor with a turbo and were going to push about 12psi. The motor with this setup put out 315hp 275 tq at only 9psi. this should be fun:)

the 2jz with all the acc. shed off and a w58 trans weighs only 100lbs more than a fully dressed BP.

Also i thought you all would want to know that this is not an expensive build due to the fact that i got the running motor for $100 and the trans clutch and fly wheel for $400. It is going to run a supra computer for the engine and the miata computer for the body. the shifter location is only and inch forward of the stock miata location but i think i can deal with that. This is all being done in a garage in the little old town of Mt. Airy MD with a bunch of 24 year old guys who have to much time on their hands if you have any more questions please feel free to ask.

and if any one was wondering it should handle ok still and all i want to do is make 50 year old guys with their 03 corvettes and 20 year old girlfreinds cry everyday.

Very cool, I cant wait to see it completed. I think Ive pretty much decided that I am going to do this one day, haha

Cool, thanks for dropping in, no pun intended. An inch forward on the shifter is not bad at all. That could always be corrected with an offset shifter if one wanted to do that.

So are you using the Miata diff and halfshafts? At the power levels you are taking about that is completely doable as long as the trans is not ridiculously short geared (torque loading).
