Question Need Help! Trying to make a Twin VF39 kit for my Supra.

So heres the deal, since you STi guys sell your awesome BB turbos for so cheap, ive decided to make a Twin turbo kit for my '89 1JZ Supra. Currently I am running a t3/t4 that will hopefully be good for 400rwhp but i'd like more. I figure 2 vf39's should give me great spool and have the capabilities of producing ~500rwhp.

Question: Is there easy access to aftermarket flanges for the inlet and outlet of the VF39?? I see 3 pages of people selling these turbos but not a single one has a picture of the turbo. Ive seen the turbo in the car, but i cant figure out what kind of flange it is. I will probably try to buy two downpipes and use those for the outlet, but they are really wide and i am uncertain if two will fit easily in my engine bay. The manifold will be easy to make, im just worried about the flange situation and where to purchase these flanges so my life can be that much easier.






p.s. sorry about the dirty engine bay.
Thanks,

Jon

If your going for 500 hp I would stick with the single turbo. There is a reason for the twin turbo to single turbo conversion. If you still feel like going with a couple of suby turbo's uniquemotorsports sells just the flanges they are about 25 each.

I dont have to stick with it, but its fun. Not true on the single, some of the MKIV and MKIII supra high high hp cars are twin. Ex. MKIII - Orin with a 1.5JZ (2jz bottom end) made i believe 836rwhp with two of the t3/t4's i am currently using. Also, Ken Henderson, the owner of a MKIV with a HKS TT kit and HKS Stroker kit made 1110rwhp on boost only at our big Las vegas meet this past year.

Yes twins can be a pain in the butt, they are more unique and can be more fun in my opinion. Also, i can sell my current turbo kit for what it would cost me to make a twin kit.

if you would like twin, and want the uniqueness factor, go for it check www.atpturbo.com for flanges, otherwise, you could also buy some STi downpipes and cut them up to use them how you need them.

i would stay with the single, i've seen lots of supras makin 1000+ on a single t-78 conversion. i thought about buying a supra and couldnt afford it, but if i did, i would definatley do the single t-78 conversion with alot of internal work, that makes for an incredible car.
