At $3,000 for a full supercharger swap/install, you might as well go Turbo for a few thousand more, the gains are MUCH higher I hear.

 

I figure I can do mine for $5-600.00 shopping around.
What I found for $125.00.

 

Probably already read it, but 2003 Super Sport has the ZZP kit. He says the pulleys on ZZP are different, a 4.2 on the M90 kit is equal to a 3.8 on the L67, and the final cost would be about $2,500 labor and parts combined, and you'd be running faster than stock L67's.

 

Riggs,

The $300 estimate is the labor costs for ZZP to put their m90 kit on your car, that's what I said $300 for when talking about the cost of the kit.

 

the gains in turbo applications are higher, but i dont want the headache of dealing with transmission problems. im not planning on running the track anyways, i just wanted to build a fast car that looks great. my goal is different from others.

the reason the pulleys are different is because of the higher compression my engine makes vs. a stock L67

 

I'll be installing an SS M90 kit on my 03 SS this weekend. Yes, the kit is more expensive than a traditional top swap using junk yard parts. I'm looking at ~$1400 once I receive my core charges back from ZZP. That said, it seems worth it to me- I'll gladly pay a little extra to avoid alot of the hassles involved with a top swap.

The SS M90 kit is a glorified intake manifold replacement.

A top swap is just that- replacing the entire top end of your engine- plus more (balancer, L67 harness, L67 sensors/wiring, sourcing a tune).

 

Well even with the ss m90 kit you need the tune. I like the fact that if something goes wrong in the supercharger I can just drop the belt and drive away with the top swap.
I pretty much got everything with mine, the top end only had 4000 miles on it. Was redone and it spun a bearing.

 

Check, check, is my signature and Picture working? check, check.

 

The SS M90 comes with a tune in the form of a pre-tuned PCM from ZZP. Plug and play, really, as opposed to trying to tune your own car or find someone capable of tuning it (not alot of decent 3800 tuners out there) if you top swap it.

I'm not knocking guys who top swap- I'm just lazy and it's way too much work for me.

 

True , but seems 2003supersport was having issues with his canned ZZP tune and still had to have it custom tuned.
