If you're after a better drive on track, have you looked at a 1.5jz conversion that would give you more torque?

I think a great setup for a track vehicle would be a 1jz-gte (vvti if possible and an easier swap since you have a 98) with the r154 and small single (maybe a 6262?). It should be around 400hp on pump gas with over 500 on a race gas. Perfect for a track car IMO.

The high revving nature of the 1jz over the 2jz makes it a better choice for a track or even drift vehicle.

If its not sequential then you may have quite a bit of lag. 2jz's have a few options on twin upgrades, but i have no clue of results. The few gt28 twin setups on 1jz that i have seen proven are really laggy, but look sweet.

Start here with your shop if they bring up going single: http://www.supraforums.com/forum/sho...otting-success

lots of good information. Good luck on your build.

If I wanted very fast spool and early torque, I'd use a cast T3 flanged manifold with a GT35R.

Thanks for all the help so far. Still undecided. My tuner says he doesnt do forums. I told him its about time he did. I did my whole BMW M3 build off the forums..well about 70% of it...and it turned out just incredible! Forums are a TOOL. Its up to the user how its operated.
So, he said he would look at this thread and all the links. I think he SHOULD!

As far as pics. Not much to show yet...but soon! I will be able to show my newly recovered front seats with the ultra suede inserts, the memory foam and gel built in cushions, the built up center console arm rest too.

My paint and body guys will be test fitting my new Vertex front bumper tomorrow!
I can shoot some pics of my new but unpainted wheels too.
We decided to use Dupont paint and Dupont IMRON CLEAR for the wheels and bumper.
pricey stuff, but the Imron CLEAR COAT will be tough as nails.
Its good for Mach 2 jets, its good for my wheels and bumper!

The wheels are BLACK Enkie 5 pointy star with the lips painted in body color. I could have gone SAFE with gold or all polished or chrome, but I have done all that before.
This will be quite different. We taped up one wheel in red vinyl tape for looks and decided to try it in paint.
It will be different from the pack, for sure. We'll see....how NICE it comes out! I hope.

Anyways, thanks for some really great advice, leads and links, guys! In the end we will GET R DUNNNN!

If you track it then why not a high boost big single with an aggressive anti-lag which will be as instant as it gets.

The key is the tune and the ems such as vi-pec v88

He wants to road race so big Turbo is 6262 or 6265 will be perfect no matter what engine you go with 1jz ,2jz,1.5jz, 1.6jz whatever engine you go with.
Save yourself the hassle, time and the frustration, with the new technology you don't need a twins setup to have fun SC.

The boostlogic compound is in house install and tuning only and even if it's not i wouldn't let anyone just tune it for me.

6265 .70 or .68 ar with some hks 264, 1000cc injectors, full EMS, good tranny will be more than what you are looking for.you don't need twins to make that kind of powerband you do that with a nice single setup.
Turbo these days doesn't have to be big to make alot of power the new 67mm turbo will spool like 62mm and will still make the 900-1000hp so you think about

62 spool like 60 and make the power of the old 67mm 700rwhp

Hope you make the right decision

No offense to ur comment but abti lag sounds cool and all but is sooooo hard on ur turbo and motor. Makes me cringe.

Not really that hard if tuned right, I daily drive a car with antilag on a stock 100k mile turbo and no issues so far and thats 30 psi on a tiny peashooter turbo.

A real good tune is a night and day difference in how a car spools etc and it has taken me many many years to find a real good tuner of sems and with that being said I had a 6262 on my mkiv and it spooled real quick so fast that I was looking for a bigger set up with more lag...

I understand where you are coming from but for his application he needs a smaller turbo , road racing something that will stay in boost at all time not a HWY monster that spool at 5000 rpm .

I helped my friend build his mK4 3.1L, the car was built for race racing but it has the wrong Turbo on it gt4294 with 1.10AR with some highlift 272 cams, if you ask me this is a highway monster, but that's what he wanted but he will soon find out that he has the wrong combo.

i had a 6765 billet turbo on my SC and that thing spooled so fast for me i had to drop the CR , it spooled like the stock twins full boost (20 psi) at 3700 -3900 rpm i can barely keep the car on the ground that was the best setup for the road course not HWY but i wanted a hWY car so i am changing my setup.

Maybe some of you don't have any exp with al but you will have power whenever you need it even off high idle and it can be wired to a switch or other options to activate it.

I have a friend who road races an evo 8 with a large frame turbo and it will make 38 psi instantly when al is on however when it's off it gets 30 mpg and will cruise very nicely so it is there when he needs it and of course not when you don't.

I dont doubt my tuner is very talented but I asked him to read all of this thread and then remind him of new posts...until we/he decides what we are going to do. Guys! Please keep writing. Thank you!
