What turbo should I get????
looking to turbo my gs300 and wanted to know what’s a good size turbo that’ll flow right. I have stock Internals, and want to put down at least 280-350whp for now after I upgrade my internals I’ll be swapping for a bigger turbo. I searched but couldn’t really find anything for the 2jzge most of the information is for the gte but to my knowledge the heads flow different any information or even links would be greatly appreciated. Thank you in advance!!!

If you plan to go up in power later, which you will, just get one turbo. I'd recommend a Borg Warner S300 in the 60-70mm range. It wont be super under powered around 6-7 psi but will really wake up when you grab some GTE rods/pistons and go 15-20 psi later. Plus, they are ridiculously cheap/reliable to maintain and rebuild.

The limit for the GE engine boost begins with the stock CR, which is 10:1 (vs. 8.5:1 for the GTE). The Aristo/Supra GTE ECM retards spark under boost, and also on shifting to minimize damage but for you that would be aftermarket. For more power you also need better rods.
About 58-62mm is big enough, but you have to be careful of your automatic transmission. The A650E 5-speed (which is what I think you have) is only good for about 325 hp. There are some DIY fixes (shims) here http://is-elite.com/?cat=3 and shift kits http://www.transgo.com/products.php?...dcountview=Yes but no hard parts.
Start looking for a 200mm LSD in your choice of ratio.
