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.

 

Where abouts in Texas and where did you get the engine? Looking to do the same in the future...

 

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.

 

VVT-i turbo's are NOT ceramic like the non-VVT-i turbo's. I found that out long after I sold mine for waayy to cheap. Keep em, they are just as good as the USDM ones.

 

dude this thread is olddddd...check the date lol. I went a different route.

 

So what did you end up doing?

 

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

 

Got any pics?

 

Cost to date?

 

ditto.....

 

I rather not say the exact amount. But just find an adverage price on a 98 GS300 and that's probably how much I paid.

 

You are looking around 6k for a swap and basic single setup.

 

" back pressure " not good for turbo carsopen it up car will perform better.

 

I'm a little confused. A basic swap comes with the twin turbo, so why would I need a basic single set-up or does the single set-up refer to something other than the turbo?
