There is a single turbo GS430 who is a member here. Adding link in a second.

Thanks DaveGS, any SC's out there anybody ?

 

i don't know of any blower on the gs430....

there is some guy with the sc430 putting on blitz twin blower

 

How come the S/C off our cars won't work?

It seems that the very slight differences between the 400 and the 430 could be easily over come to retrofit the 430 with a S/C kit off a 400.

Anybody?

 

If it works on the SC it should work for the GSwouldn't it ?

Any info would be appreciated

 

Not necessarily. The differences between the SC and the GS are not as minor as a GS400 vs GS430.

 

i would think so too, shouldn't hard for the bolt on. but then the tuning is the issue, coz' the 430 has different fuel mapping etc... i suppose

 

I don't think the fuel mapping would be all that different. Even if it was you could manipulate it with the same thing we do, and SAFCII.

I wonder why someone hasn't given this a closer look. I seem to remember that the GS430's engine bay looks almost identical to the GS400's. Even with slight changes, I don't think (not 100% sure) that it would be entirely out of the question to physically make it work. Maybe a couple of brackets would be different. For somebody like RMM who has the ability to build any bracket they want, I don't see what the big issue would be.

 

I was considering the RMM SC last summer for my 430 and the info that I got from Eric (of Rmm) is that their kit shulde work on the 430.
He said that since it was tested on the 400 and not the 430 he was not 100% . but you would have make a new mounting bracket because the engine sits differently than the 400 and something about a different stock belt pulley.
There were too many unknowns to lay out $5K and they were not interested in making a mounting bracket. So, I just wait and cross my fingers and hope that SRT ,Pro Lex Performance, TRD or somebody else decides to do an affordable SC or turbo For the GS400/430.

 

GILLEXUS Thanks for the feed-back, seems there are not a whole lot of people driving 430's that want to modify them.

Hopefully somebody will do something, since the new (2006) GS doesn't give any indication that Lexus is going to do anything soon on the engine part.

Twin Turbo or SC would be what the 430 deserves along with a different gear-ratio and modified trans, looking racy is one thing beeing it is something else

 

Well since the new 2006 Lexus is staying with the 4.3 engine is a good sign. Maybe some tuners will see that the motor is here for awhile ( but how long) and it will be worth it to do some forced inductionon.

I think your right, there aren't alot of 430's that want to modify them to the extent of FI (at least compared to the # of GS400's) the 2005 or 2006 should add at least a few more to the pot.

I think since SRT has done it before and knows the Lex 400 motor in and out (and probably the 430 motor) It would be great if they got back in the game.
The've been there, done that, so a S/C Version II would be a better mouse trap.

I know we all want something affordable, but a decent kit isn't going to cheap. Look at the IS300/Gs300 kits, there are quite a few kits available & it is fairly competitive, you'll still pay around $4,500- $5500 for one of those.

I',m curious, how many 430'ers would be interested in FI ?? I would be-- That's one

 

Make that two (me)

I know the prices are relatively high but if you can get enough out of it (150+hp?) it would be worth it

Also I am wondering what Lexus is going to do with its AMG/M devision, if they come with FI, than the tuners are basically out as far as FI is concerned
Lets hope they start with it as soon as the 2006 GS comes out

I'll keep looking around, if you hear anything keep me posted

 

I would be 3rd.

I think as the GS430s drop out of warranty you'll see more owners considering/doing more extensive modifications to them. I know I did on my GS once its warranty period was over.

 

Dave beat me to it.

This is probably the #1 reason you don't see the numbers of 430's modded. It voids the warranty. If any of you have ever had to have ANYTHING done and paid full dealer prices to do it......you'd understand why nobody wants to do it twice.

I suspect that the similarities are substantially more than the differences, so somebody will come up with the proper changes and adapt an existing FI kit. It would be smarter than starting from scratch.

BTW, just FYI.....150hp is a boat load of HP. FI is not simply strapping on a turbo/SC and magically it happens. There are a bunch of other things to consider/install before real HP gains happen. Most kits are designed to be conservative in order to keep them as close to plug and play as possible. Unless you keep them at the lowest most moderate power levels (which you won't), you will almost always need additional components to keep you from having to pay $4k for a Lexus motor. Moral of the story??? Do 150HP worth of research BEFORE diving into this kind of project.
