Top Swap setup questions

Top Swap setup questions
So i just acquired a top swap kit essentially from someone local. Its a Gen 3 m90, with the L67 heads, fuel rail, injectiors, intake manifold, boost solenoid, all the pulleys, harmonic balancer, and tensioner. essentially everything i need, however now comes some questions. the setup is off a 97 bonneville ssei, and i'm positive with the shorter dogbones the setup will be fine, but what do i need in terms of switching the electrical components and guage setup, etc for the supercharger itself. also, should i worry about the heads having a 160k miles on them. would it be wise to upgrade the rockers and replace the springs now too?
any info would be appreciated
thanks

Regarding the boost bypass valve solenoid- I'd recommend not using the solenoid. Just connect your boost bypass valve to the blower via vacuum hose and let it operate by manifold vacuum. This is how I run mine, this is how ZZP advises you do it, and it's just better and easier.
would it be wise to upgrade the rockers and replace the springs now too?

your sure on the electrical stuff, cause the guy told me i would probably need a different wiring harness.
otherwise i was gonna get a custom tune right away after the install, and as far as the boost solenoid goes, wouldnt that mean i'd be making boost at lower speeds if i didn't have it on?
also, i've got the zzp downpipe with the the rest of the exhaust pretty much replaced but i'll probably look up prices on some of those springs, but would you recommend for brands as far as the rockers?
Thanks

You need l67 injector connectors for sure. A few things will be needed, check the top swap wiring kit from zzp. If you have any questions just ask me. Mabye get a valve job on the heads.

You'll want Multec-2 to EV1 adapter harnesses.
Besides the injector harnesses, the only adapter/different harness you'd need would be for an L67 MAP, IF you want to run one. I'd advise against it. I'd use a tuned L36 PCM and use the stock L36 MAP. I'm doing this with great sucess.
All the other sensors are the same. The stock main engine harness works just fine- I'm still using mine.

If you do want to use the BBV solenoid, you WILL need an L67 PCM. I personally think it's completely unnecessary and a waste of time (and possibly money).

yeah, and thats what i'm planning on sticking with, i dont see the sense in spending more money than i have too.
and Enzo, when you say having the valves done over, how much would something like that run cause i thought about the same thing especially with the heads having 160K + miles on em
