and don't forget to change the turbo to single turbo

while at it, forget about the stock tranny, having it bolt up with the 2jz-gte engine would be a nightmare. just get the getrag 6 speed as well!

hardly enough. those are just providing marginal help over what's from factory. to make the cars rigid, it has to be well thought out from beginning (like for the m5 and e63).

i have driven 2gs with some very good power, and also all the braces on. fact is, when i turn the car fast, the body just couldn't handle as well as what a stock m5 (for example) can provide. that told me how important body structure design is

mike, i don't think the 450h is using the same cvt as the 600hl? somehow i remember them talking about the cvt in 600hl, it's computerized, it's actually more or less the same 8 speed, but computer controlled on all rpm and the hidden "shifts".

i like the isf engine + hybrid power, that's going to be fun. i believe the hybrid engine in 600hl is pushing quite a bit of power. ls460 380hp, ls600hl 430+hp, so that's at least 50hp, not to mention the engine in 600hl is detuned meaning the hybrid is pushing out more. that together with the 410hp isf engine, ummm... well, at the same time i am not sure if all that will fit in well

 

Totally not worth the effort. Just buy the M5

 

I will check the greddy supercharged version for this engine.

 

I think it only is for the GS 430 and was good for only 350hp or so.

Henry not sure about the tranny but leading towards what you are saying.

 

GL with your project..

 

200 shot wet kit.

 

Oh Jesus!

 

Good thought but all that money dumped in won't worth it in the end.

 

I second and third and fourth that (didn't count how many responses actually suggested this).

Building a GSF on such an aging platform is a no-no. The new M5 (to be out very soon) will have everything you need in a top-performing sedan. Including the best tranny of all the performance sedans out there (dual clutch 7-speed manual/auto) and arguably the best engine. In the past, it wasn't easy to tweak M5 engines, they were naturally aspirated with high compression ratios. The new one will be a TT V8. Much easier to tweak / work on. All the plumbing is in place. Compression ratio is low. Boost pressure will be the easiest and least expensive way to tweak the car for more HP / TQ.

Good luck.

 

or the "cheaper" route, the new 550 is already 400hp tt v8 out of the box

 

anything can be done with money....just how much is somebody willing to throw down?

AEM can build you a custom ECU that will work. Just not cheap.

fully built internals on the GS460 using all custom stuff. custom turbo kit...etc.

contact SP Engineering or AMS and start looking into 2nd morgages.

 

found your solution.

do a full IS-F motor swap along with rewiring the motor into the factory wiring. Then slap in this.

Then you have 600hp.

 

Totally not worth it. The drivetrain won't handle 600HP. Neither will the suspension. You'd have to do a lot more work than just an engine swap + turbos. Yes, with enough money, you can do anything. It's just not worth it. Buy an out-of-the-factory-ready E63 AMG or the new M5.

Why would you want to mod such an old platform, when a new GS will be out in 6-8 months? And, a year after that, supposedly, the real GS-F.

 

I completely agree. Toyota/lexus is not know for enthusist(driving experience) till reciently so their chassies are all built to numb the handling.

Either way, we all know the value in doing such a thing is possible, just not cost effective nor practicle but modding a car never is.

 

even cheaper route is the new INFINITI M56 with 420hp.
