Does anyone know if an rmm suercharger made for a gs400 but with a custom bracket for a gs430 fit an LS430?

Anything can be made to fit. The problem is the tuning. May have to run a standalone or some sort of piggy back system for fuel management. All things are possible though.

Well the reason I'm asking this is because I have a rmm supercharger (which was made for a gs400) but has a custom bracket to fit a gs430, which is essentially the same engine as the 4.3l in the ls430. The engines are interchangeable between the gs430 and the ls430, so as long as there is sufficient room in the engine bay of the ls430, i don't see why it wouldn't work. Also the S/C I have also uses a haltech interceptor ems. So basically it should work, I would just need to see a good picture of a ls430 engine bay without all the plastic pieces in place.

Turning any NA engine into an FI engine is going to be hard work. These are good engines, but you will probably have to reinforce the internals a bit. Also, putting down more power equals making sure other driveline components can take the extra power. How much of a gain are you looking to get? Interested in seeing your work as I have yet to see anyone bolt a turbo or supercharger onto an LS430.

I understand what you're saying but I'm not sure if you understand what I'm saying, maybe i didn't explain myself right.
I have an RMM kit with a custom bracket for a 3uzfe, in fact the exact same kit I have has already been on 2 other gs430's with no issues and approx 380whp with only mild tuning. Everything held up fine, only problem was transmission hitting the rev limiter sometimes, which was mostly fixed with a valve body upgrade. This is a plug and play for any gs430. Also already has a haltech ems which is very useful and basically a necessity if you want to be around 400whp. I have 2 different pulleys depending if you want mid to low whp range, or if you want high 300whp to low 400whp. These transmissions are stable to about 400whp. These engines were not built or reinforced at all!! So I would think that as long as there is room in the engine bay of the ls430 then this should basically be a bolt on supercharger (except for maybe having to redo the intercooler piping due to the ls430 being a bit larger than the GS.

I'd say go for it. Like I said, anything can be done.

Racingstylez has a single turbo set-up in his LS430.

If you do this, I may be sure to follow.

The only problem is there were only 27-30 of these kits ever made. And they rarely go on sale. Also 99% of these kits are only for the gs400 (different engine) the one I have had a one off custom bracket made to adapt the kit to a 3uzfe engine. Also rmm no longer has the blueprints to re-manufacture the kits. Trust me I checked before i bought mine from a fellow cl member.

Well when and if you feel like you want to undertake the project let us know. I will subscribe for sure! Car already feel pretty powerful, can't imagine an extra 90 hp!!

what he was essentially asking (or atleast he was in the gs section) is are there anything mounted factory in the way? like is the power steering pump,ac,any of the pullies, or any of the accessories gonna be in the way on the LS430 as they ARE not on the gs400/gs430?

yes ANYTHING can be done but sometimes things arent worthwhile to do


Lalex who did you pick this kit up from? i see your already on the list

BTW he's not kidding and we only have 8 accounted for still (although if you scroll t post # 10 there are still some around)

even less of the LMS S/C made and still around they also fit the gs430 but without custom brackets

I picked up the kit from a guy in vegas who had purchased it from 00lexondub (i think was his name). It has a custom bracket for a gs430. My dilemma is, when the kit was shipped to me, ups damaged the box and a few critical parts were lost. So basically I have a kit minus a belt tensioner and a few missing bolts, so I have >90% of the kit. The cost for me to have the few parts I need custom mad is approx 1k. Not too bad I guess, but really I just haven't got around to doing it. I have had this kit for approx 4-5 years now, sitting in my garage. Besides for that it has the vortech unit brackets injectors and haltech ems system. Oh yeah also piping intercooler larger rcc injectors, blow off valve and a few other things. Would cost near 5k just to purchase all the parts (not counting the custom parts), to reproduce this kit.
So I'm trying to decide if I should put it on my gs430, sell the kit, or possibly purchasing a ls430 and putting it on that.

Also thanks Sakataj for helping explain the information i'm trying to find out.

Well I got the supercharger working on my gs430. If you guys want to check it out here it is. I don't see why this wouldn't work on an ls430 with some new intercooler piping.

imagine an ls with this power

enjoy

Great to see you got it installed! The 4.3L V8 sounds meaner in your GS, esp after the mods. Great job, you've made one good sleeper!

Thanks. It took many years and a lot of money/effort to get it to work the way it does now.
It is a beast to drive!!! One of you ls430 guys should step up and get this to work on your ls430's that would be awesome. (half of me still regrets not having purchased an ls430 instead of my gs) but oh well thats in the past now
