I like the Boost Logic T67 kit and the built transmission. And that's already $6k.![Crying](https://www.clublexus.com/forums/images/smilies/Peace.gif)

They have already done systems on the Tundra 2UZFE V8.
Not enough room, Where U see the Camero's with the turbo right under the trunk, That is not 4 me.
Where the 2 downpipes come down, There is not enough room, Maybe for a super small as turbo but not a T04.
Plus because of compression ratio 10:5:1, U can only run 4-5psi MAX boost on pump gas.
If U look at their Chart on compression U will see this....
If U got any info on this..... Let me know, because it is the cheapest route I see...

(a T4/62 is F%$# huge) How about a Stock TD05-14B from 1 gen eclipse, can boost upto 18psi efficiently - no hot air, cheaply available with an internal wastegate, can use the BLITZ boost controller which controls boost gear based, Rpm based, and tune the fuel with afc.. How does the STS oil supply kit work, Can it be purchased seperately? - they just didnt want to sell me the oil kit seperately.
What I like about the turboVSsupercharger is the control of boost in our case run less in 1st gear so we dont hit the rev limiter and tuning is definetly better - Somebody try this out that has more knowledge than me.
thanx

Yes, I know that STS says no intercooler is needed because of the pipe length... while there is some heat drop with the longer pipe an additional intercooler would still take out some heat and that will give higher max boost tolerance.
A big difference between centrifugal superchargers (vortex, paxton, powerdyne) and turbocharging is that turbocharging can reach peak boost at the engines torque peak. This is the most sensitive RPM range for detonation because torque peak is also cylinder pressure peak and that is when detonation is most likely. So, you may need to run a fuzzy logic boost controller that pulls out a little boost at torque peak and then puts it back at higher rpm in order to run similar peak boost as a centrifugal supercharger... even so the turbo will make more power under the curve and therefore be faster.
Now, when it comes to packaging you may need to run two smaller turbos for maximum ground clearance. There is no other advantage to two small turbos vs one larger turbo.
Of course you could install the turbo where XS Engineering does... right after the manifold... and remove the factory catalysts. You can re-install a catalyst after the turbo but without certifying that configuration you will not have emissions legality (this applies to any turbosystem with or without the factory catalysts and other emissions components).

Here is a picture of the first XS Engineering low mount single turbo SC430 using a Garrett twin ball bearing GT3540 turbo.

LexT, I do not think Lextreme's bracket would fit a GS but the supercharger from Planet Soarer may work... possibly requiring a hood bulge.

I'm not gonna do turbo for my GS4 anymore. I just picked up a 87 Turbo supra for pretty daym cheap. So I'm gonna mess around with it for awhile and find a cheap 2jz motor to do the swap. That way i can keep my GS in the garage during the winter and mess around with my turbo supra. How is that sound?
1987 Turbo Supra for $1000
1993 N/A Supra wheel for free from my friend.
Next HKS BOV, Front mount Intercooler, Turbo timer, Custom cat back,Suspension, and new paint job. I guess all the money i'm saving up for my GS wheels gonna be on this new supra.
