Headers, colder air intake, rockers, cam, aftermarket/ported heads, cooler spark plugs, cooler thermostat. Don't forget to find a tuner/knock gauge, so you know how much KR you're getting.

Hmmm, I'm probably better off just replacing the engine/tranny from the wreck and and go from there.

 

Well, thats all true. those mods do help with KR, but the quote was talking about the zzp SSm90 kit, not a top swap. you have the benefit of running a bigger pulley size with the SSm90 kit, so if you have KR with a 3.8 SSm90 pulley, just run a 4.0 or 4.2 SSm90 pulley

with all my mods, i still had KR with a 3.8 SSm90 pulley (the equivalent of running a 3.4 pulley with a top swap). Thats why i decided to intercool it, and it killed all KR. i could drop a pulley size, but need the gas milage instead right now

 

with a top swap you'll basically have a stock L67, no longer an L36 since your replacing basically everything. you'll no longer have the higher compression of an L36. a 3.8 pulley is the biggest pulley they make for an L67.

Wbody store top swap kit is not the same as the zzp SSm90 kit. Wbody store is basically a kit that makes your engine an L67, replacing your heads and up.
zzp SSm90 kit basically replaces your LIM and throws on a supercharger.

you wont be able to run a 4.0 pulley with the top swap.
you can run either a 4.2 or 4.0 pulley with the zzp kit (about the same as running a 3.8 or 3.6 pulley on a L67, respectively.)

 

I always thought that a 3.8 SSM90 pulley would equal a 3.8 pulley on a top swapped L36.

 

if you top swapped an L36, it would become an L67. your changing heads and all with a top swap.

if you did the zzp kit, you would still have an L36 heads with a supercharger.

 

See, I did not know that. I always thought supercharged L36's, whether L67 Topswapped or ZZP kit equipped would always maintain the higher compression advantage over a regular L67. So this makes me think...a ZZP kit equipped L36 will be slightly faster than a topswapped L36 generally speaking. The one thing I will have in my favor is 3.29 gears, whereas most L67's have 2.93.

 

If you top swap an L36, you will still have the higher compression. The head chamber is the same size between L36 and L67 heads. The pistons are where the compression difference comes from and your not changing them. So a top a swapped L36 will make a little more power than the same mods on a L67.
Before I do my topswap I'm getting the other mods ready, already have: A front plog and a 3" downpipe, looking to get an cai next. The plugs and thermostat will get done when I do the swap.
Having run a few different cars with superchargers over the years, the biggest thing I dont like about the sm90 kit is the one belt. So nice if something breaks in your s/c just yank the belt and still drive home.

 

Isn't the compression in the block, which is what you don't replace? So you would still be running a high compression boosted set-up on a top-swap.

 

SERIOUS!? This gives me renewed vigor on the supercharge upgrade! But now since there is debate I'll have to really get to the bottom of this, perhaps BumpinMonte will chime in and give us the encyclopedic truth on it all.

I originally thought Topswapped or ZZP kit supercharged L36's would maintain their higher compression, now I'm not so sure.
