JDM Aristo TT swap
Going to be doing a JDM Aristo TT swap on my 98 Lexus GS300 in the up coming week, and I just wanted some opinions on the setup.
-JDM 2jz-gte twin turbo (280hp @ 5600RPM - 315/4000RPM)
-SS Autochrome Front Mount Intercooler or Greddy Front Mount Intercooler
-HKS Turbo Back Exhaust
-Autometer Boost Gauge
-SS Autochrome Downpipe
-Walbro 255 Fuel Pump
-HKS Air Intake with Mushroom filter.
-HKS SSQV BOV
Finished HP = ~320-330hp
Total cost:~$5,800.00
The engine isn't the USDM 2jz-gte (steel turbos, 550cc fuel injectors, camshafts) But thats a upgrade for later down the road. This is the JDM 2jz-gte on the Toyota Aristos thats why it's 280hp. Anyone have experience from SS Auto chrome, I'm just getting a FMIC and a Downpipe from them, I hear that they have straightened up and as far as FMIC and Downpipes go, no problems. I wouldn't trust their turbo kits and manifolds though.
I wanted to buy a better brand FMIC because later down the road I don't want to have to buy another FMIC when I add more performance mods and run high boost, then have my car overheat. And just get a SS Autochrome downpipe and replace it later down the road, since downpipes are pretty cheap compared to a FMIC.

Just look around and call around. Most likely the person I'm doing the swap with are sourcing the motor for me, from somewhere in California. I wish I could of got the USDM 2jz-gte but they are much harder to find and if you do they are more expensive.
The XSpower intercooler, manifold, and piping are all of good quality. I have a few buddies all running 500-700hp with the XS manifold and intercooler with no problems. For my car I'm running a XS manifold and intercooler as well, so far no problems after 5 months of boost. Two of them have MKIV supras running about 600-700hp on that manifold as well with no problems for a year now.
Their early versions of manifolds were prone to cracking due to thinner tubing walls. They fixed that about 2 years ago so I haven't heard too much about cracking since then. I just wouldn't trust their turbos and wastegate. On my car I run a Turbonetics turbo, Tial wastegate, and HKS SSQV bov.

JDM 2JZ-GTE VVT-I
True Twin Conversion
Aristo 4 speed auto transmission
3'' custom downpipe with 2'' restrictive ring bolted to stock exhaust no cats just resonators to stock mufflers. I did this in order to add some type of back pressure so I don't blow my CT-20 ceramic turbos. The JDM stock wastegate is not enough to control the boost. I hope there won't be any boost spikes.
Tial BOV (HKS sounds too rice for me)
Aluminum radiator with 2 new electric fans.
Walbro 255 fuel pump
Turbohoses.com air ram intake
Front mount intercooler
B&M Medium size transmission cooler
