GMPP LSX376 and TVS 2300 combo…
Of course, like everyone else here I am changing everything out in my ride as I go and I know that my little LS1 will have to go soon too. Has anyone here that owns a 1998 to 2002 F-body considered the GMPP LSX376 crate engine with a TVS 2300 sitting on top of it and MAYBE a little bit of the bottle on race days only?
I have been thinking about this and other combinations for a little while now. GM High Tech and a couple other magazines have done some articles on installs with the LS9 supercharger system. I have also read up a lot on similar setups, but with the LS1 engine.
Again, like everybody else here I want my ride to be fast and competitive, but I also want it to be streetable, or to be able to drive my ride on the street, if that makes any sense. Oh, and it also has to be somewhat emissions legal. I want it to perform on the good old 1320, maybe not single digits fast like some of you all here, but if that happens by accident whilst on the bottle, that would be an acceptable side affect I am willing to live with.
I am interested in hearing some of your comments on this particular combo and bare-in-mind that I am NOT trying to build a total race car please.
Thanks

This would be an awesome build. A lot of people say that it can't be done because of clearance issues, but I haven't heard of anyone that attempted it yet either. I've seen the blue ss with the ls9 motor in it, i believe that blower is similar to the e-force tvs. So far the only roots blower I've seen on the 98-02 fbody is the mp112. I would love to see someone successfully put a tvs2300 on a 4th gen

Wondering if that's too much blower for the cubes...would a TVS 1900 be a better fit? More TQ off-idle, etc. (i.e. more 'streetable' as the OP describes he wants)

Its a shame they don't make a 4th gen specific roots blower designed to clear the cowl...you know there would still be a lot of folks interested...the roots design lends itself well to road course and autox with the TQ it makes off idle.
I would agree with the earlier post, if you were just buying the lsx to run NA and wanted warranty, then cool...but since your wanting to top it off with a blower AND possible spray 1) they won't honor that warranty, 2) its not a motor forged for those requirements...you'd be better off getting a purpose built shortblock done by a sponsoring vendor. All IMHO.

^I agree, a tvs2300 on a 4th gen fbody would be awesome

Been thinking...
You all have really given me some food for thought concerning my original post about the LSX 376 from GMPP. I think I will stick to me original idea of a 402 or 408 iron block with all forged internals. Because I am relatively close to them, I have been looking into Texas Speed and Performance and some of the engine builds they offer (402 or 408). Can anybody give me some feedback on some of their engine builds?
I have also become quite interested in a D1SC Procharger setup pushing 10-12 psi from Brute Speed with the single intercooler upgrade plus goodies instead of the TVS 2300. I already knew that in order to make one of those fit in my ride that I would have to shim and shave here and there, and all that goes away with the D1SC. Don’t get me wrong, the 2300 is awesome, but it has its place where the installation is less complicated. The reason I had changed my mind about a Procharger was because I was not too crazy about the physical position of the head unit and the limited space between it and the radiator. However, the proof is in the pudding and a lot of people with that setup are running some really good numbers.
I had also mentioned a nitrous setup and the FAST intake seems to lend itself more to this setup than the TVS 2300 route. I really want this for race days only and I admit that I have to do some homework on combining the two, but from my initial research this would be easier.
Also, I highly recommend reading the Sticky entitled “The Real Price of Forced Induction” if you already haven’t done so. It really clears up a lot of questions you might have about a forced induction application and helps you to better plan your setup.

Not anymore...
Not after I found out that the rods are weak in that build. Through this thread and everybody’s responses to it, I found that spending a little more will spare me the aggravation later on down the line. If I were to decide to go with the GMPP motor, then I would nix out the spray idea and to tell you the truth I am leaning more towards the Procharger D1SC setup instead.
