Build Happening soon.....2jz Swap

[pnig]

the new corvette is pretty close... starts at $51k, curb weight is a bit higher at 3300 but its got the power to start and has room for more, looks great, and has RWD

Even if it's close.. there's still not very many choices still in that price range.

Besides it's over 500lbs weight difference and that's a base model vette. If you start with an FRS it would be less. Anyways, it's the fun factor of a having a custom build which isn't easy.

Hell, of a 2JZ fits into an FT86 I'm going to shoehorn one of these into mine...

A S54B32 motor in an FT86 would be an amazing swap

My plan and goal is to have this build done by the time January gets here as I will be in school for my master's and have to space out everything. I have enough to get decently started as I was offered a good deal on my GTR and have plenty of cash left over but school is my main priority. I will keep everybody updated.

Any updates on your build? Seems like there are only a handful out there.

What car is 2700 lbs, RWD, looks good, has the power output capabilities of a 2JZ-GTE, and in this price range with a completed swap?

You can always get both. lol That's what I plan to do once the C7s drop a little in price.

I think the pushrod v8 would be better for keeping the weight distribution closer to stock when compared to an inline 6. Just saying.

What about weight balance? Wouldn't the longer (longitudinally) 2jz push the weight further out front? That is, unless one can mount it even farther back than the FA20.

Also, OP, I take it you've also sourced the transmission as well?

Because this way is MUCH more personally satisfying?

Full interior, Ac , all electronics working and also abs/ traction

Not bad. Still unbalances more than stock (stock distribution is closer to 53/47, iirc), but that's not too bad.

I guess if you get too much front dive, you can put in stiffer springs, or if you begin to lose the rear traction at higher power and speeds, you can always add aero to plant its ass back down onto the road .

Horse.

A loaded 2JZ (longblock, accessories, turbos) without flywheel is over 500lbs wet.

That is exactly what I ordered for my race suspension last week. Stiffer spring upfront and softer spring in the rear; rates 11(f) and 7(r) respectfully.

I am curious to find out the final weight for my car (2JZ BRZ). I will definitely keep everyone posted once we wrap up on the project and I get her to a weight station. Got a feeling I'm going to love this plump SOB.

what suspension did you end up with?

sick! I heard good things about their race suspension.

In for updates guys I love the idea. I have a 2j mk3 supra I've debated on swapping to the frs.

I've spent a ton of time on the S30 Z forums and this kind of swap is regular place in a similarly weighted Z car. (just sold my Z for money for the FR-S lol). For the Z's, swapping to a V8 always puts weight more towards the center making the weight distribution better.
I imagine that swapping an aluminum V8 would net better weight distribution than any inline 6 in the FR-S/BR-Z. weight distribution would probably come in real close to stock with the aluminium V8 while adding a straight 6 of any kind will throw weight way out towards the front. My guess is the split would come to 54.5F/45.5R ish.

Oh and also for a jack of all trades like you said you want a V8 would probably be better anyway. they typically have better torque curves for multipurpose setups. 500-600hp 2jz might have a bit more turbo lag than you would want for something like autox unless you go with a sequential setup which i dont know if you could fit that in the twins engine bay. would be sweet though haha

Dont get me wrong though. I dig the idea of a 2jz swap . they make a ton of power and i dig straight 6's thanks to my love for S30 Z's. Good luck with the swap.
