....twin turbo scorpion kit, only 30k

 

....

 

To my knowledge, the RMM supercharger is no longer available, contrary to what is posted on their site.

Jawnthen has had an SC on order with them for about 6 months. Every time he calls Eric @ RMM he says that they will have all the parts available by the following week and to check back then. After calling on average, every other week for 6 months, I'll take that as a sign that there are no SC's left.

If anyone has ordered and received a supercharger from RMM, between June 2004 and now, please let us know.

Any other DIY SC kits offered for the GS?

I think not.

 

turbo kits are better and more efficient(less parasitic loss), but they cost a lot more also..

 

hey i read something about SOCALgs4 gettin a SUpercharger that is not SRT or RMM... maybe someone can figure out what he is up to/.

and jimmy .. thanks for the props.

 

wait a second... SRT makes supercharger? i went on their site and found nothing on any supercharger... they did have something on the GS400/430 models but it was a dead page and nothing was showing up.......

i guess SRT is the prime choice for my supercharger whenever that time comes...

 

Does this engine look familiar? Yes, its a GS400 4.0 1UZFE motor. This motor was transplanted into a IS300. This V8 also powered by a T66 single turbo located at the passenger side. The turbo is considered a low mount. The owner also have NOS.

I asked the owner how much power he is getting. He stated that he only running 6 psi and getting mid 700 hp. I wonder is that with NOS or without NOS and the other question is rwhp or bhp? Lets assume its bhp. From our experience 6 psi can produce about 350-400 rwhp. Even with NOS, I doubt he got mid 700 hp. That mean he must squeeze at least 200-250. Oh well, what can I say?

 

SRT stopped carrying the SC for the GS4 a while back and only does TT right now, but they may consider bringing it back (with a new design) at some point.

 

They did at one point. There is some rumors about it coming back but at this point, it is a non-existent product.

 

so a turbo for the gs400/430 is possible? hmm... if thats the case... i would much rather have a turbo than the SC... buts a decision down the road.... that engine does look really beefy and mean...

i like it...

 

SRT ONLY sells a twin turbo for the GS4. As I recall that goes for $20-30k depending on what's included.

Any others more reasonably priced ?

I'm not talking about custom one off jobs. There are definitely plenty of those around, but those are not price or DIY friendly options.

Who actually sells a SC or Turbo DIY Kit, plug and play, whatever you wanna call it ?

 

my goodness, a tt kit for the GS4 would cost about half as much as a new GS4 .

will the prices ever go down? even the good big turbo kits for supra's cost less than half of that..

 

well xs engineering did a turbo setup for one of our norcal cars, taht's one option if you can pay the price
