The only way to adjust boost is pulley size-- you would need to source a larger pulley. (Actually this SC as the bypass there might be a way with an EBC but I don't have a clue...

IIRC- The original kit only used an AFPR and BIPES ACU.

hi do u still have the kit?

I have a buyer- if they back out over the weekend I'll update

Do you have any instructions for the kit. I bought the same kit a month ago and would love an instruction set if you could photo copy and mail, or email them?? Be happy to pay postage if you want.

I have already pkg'd up the instructions... The manual is quite large- but I have never read it (I'm a guy) There are actually two-- one for the JRSC- should be able to down load from moss??? The other is the BRP CS mods...

It could probably be a bit overwhelming at first but I'm sure it would go something like this...

DISCONNECT THE BATTERY -Your WRENCH WILL SLIP AND SHORT OUT YOUR ALTERNATOR

Remove starter, alternator, Intake manifold, brace, oil filter, oil sendor, all intake plumbing, fuel rail and air filter box.
Install top portion of manifold - then RTV bottom plate of manifold and install. Install brace- and reinstall starter/alternator/oil filter.

The TB gets mounted upside down on the SC and there are vac lines that get installed before the SC-- the two large ones- one for brake booster and the other for PCV. The smaller ones are for the fuel FPR and the various solenoids - The EGR doesn't get used. you'll need to extended the two water lines from the front of the engine for the TB.
The 3" vac hose runs along the back of the firewall- and the MAF w/ss "heatshield: go on driverside where the original airbox was mounted.

There are the 9-10 intake manifold bolts (reused)
12 bolts for the new IM
4 bolts for the SC
3 bolts for the brace
4 reused bolts for the MAF mount 6 x1.5
???Bolts for the pulley set up vary depending upon model

I'm uncertain of any Electrical mods needed I use a standalone ECU.

Idle will need to be adjusted as well.

If it has the original pulley set up--- checkout revlimiter's website he has decent mod with how to.

Cool, i'm pretty handy with a wrench :) The questions I have are all vacuum/electrical/fuel related. Planning to just run a power card and maybe some water injection, but otherwise stock with 8-10 psi hopefully.

I think you can reuse the 3/8" vac hose that goes to the brake booster, maybe 8' of 1/8" vac line and a couple of tee's for everything else- there's 3-4 "sources" you can use any source- just don't make a loop... The other 3/8" hose barb is for the PCV valve.

I had a hobbs switch on mine- no clue what it was for...2 other sources were vac and the other was for boost gauge.

IIRC The powercard is only 5 wires and a vac line.-- you should find some 305cc injectors-- that will help with the "lean tip in" associated with the PC. And maybe an O2 clamp
