Hey guys, I'm having trouble decided what I should do right now. When I bought my 1JZ Supra a couple months ago the previous owner had already purchased a T67 turbo and exhaust manifold. He never installed them and sold me the car before he had the chance to do so. However, a while ago I saw Albert's thread for upgrading stock twin turbos. I like how fast the twins spool but wouldn't mind a bit slower spool given that I daily drive the car. Right now I'm really considering selling the T67 and upgrading the twins. I was thinking that the T67 seemed like it would be too big for a 1JZ, but I just need more opinions. Can anyone give me advice on what I should do? :1zhelp:

It comes down to your power goals of the car if you want to maintain quick spool and hit 500hp the i say go with the twins. If you want more and you are willing to sacrifice spool go t67. Either way you will need appropriate fuel mods.

This. If you plan on keeping the car at 10-15psi, a car on twins will walk all over a car with a bigger turbo that is way below its efficiency point...

Thanks a bunch guys, I don't plan on ever going past 500WHP so I will sell the t67 and upgrade the twins. I'm @ around 19 PSI with the stock twins so I'm not sure how much longer they will hold that much boost anyway. Expect to see a unused t67 in the for sale section soon!
