Ls Compatibility chart ? Hey guys!!
For those who didn't see my introduction post here it is !! : https://ls1tech.com/forums/introduct...greatness.html
My old LM7 disassembly and cleaning process is done and the short block is now stapped in the trailer ready to go @ the shop for new cylinders boring and nikasil plating!! I'm now trying to plan my top end setup, I'm looking for a compatibility chart sheet @ LS motors, mostly wondering if a ls9 intake manifold would fit ''or is similar'' on a ls1 ? .. I'm planning on a LM7 root blown engine setup but i'm not looking to get ripped with a overpriced magnuson & such kits. Eaton m112 ''TVS2300 cheaper option'' ect.. / or weiand's blowers are so easy to get for cheap so buying a kit is kinda ridiculous to me. I'd prefer a eaton setup and go efi instead of Weiand's, could buy a Holley ôr similar efi carb setup but Eaton's seems the way to go, more simple and logical.
Any inputs ??
Thanks .. Chris

Welcome to the forums. The LSA and LS9 blowers are meant for rectangle port heads. The rectangle port heads will not fit on the 3.78" LM7 bore. The LSA and LS9 blowers will not fit on the LM7 cathedral port heads without a set of adapters. But, the same guy that makes the adapter plates also makes pulleys for the LSA blower to line up with F-body accessories and I think truck accessories, as well. It is very doable. You should definitely get new valvesprings, pushrods, and upgrade your rocker trunions.

No I'm from Montreal,Canada & My plan is to go SC ''ROOT'' .. not logically because I used to built custom turbo setups in my ''DSM&Rotary Era LOL'' and i know turbochargers will always be more efficient and cost less per hp in most cases compared to to s/c's, Well back then turbo setups were much more expensive compared to nowadays, but still. Even the root s/c setup i'm looking for is less efficient than centrifugal ones '' HP wise''.. but my goal/plan/dream is all about low boost, low rpm tq and top end, acceptable hp #'s and the simplicity of a root setup, oh yeah.. forgot about the sweet s/c whine !! lol.. I used to build cars to compete and didn't care about streetability, Go at the drag strip with endless spare parts and so on ... but not anymore .. I want a car i can appreciate every day and still beat the **** out of the little average ''I believe i'm Lewis Hammilton'' Civic Si or sti kid lol, I know i can build something great with my goals in mind !!
Thanks for the offer tho

Honnestly Nikasil is too expensive for the slight benefits it will give average setups so i won't suggest ppl to go that route. But for me, with my water intercooled root setup i plan, Nikasil will help on the long run. Manifold water/intercoolers a very limited and i plan to boost it on its limit, hot air temps from the blower might let the nikasil plating show its benefits, make it more reliable.
Hope it helped u.. srry for my bad english i'm french lolll
