Ok i have a 92 SSEI and ive got parts on order (CAI, flowmaster 80 series, dynomax supercat, jet stage 2 custom, and a 180 degree t-stat) now with those parts and stuff what pulley size should i upgrade to, pulleyboys goes all the way down to 2.0 from my stock 2.5. And also will i need a larger idler pulley also? And where can i get that and what size?

I would say with the mods listed you could go as low as 2.2" on the pulley. The idler is avail from zzp and there is only one size, this will allow you to use the stock belt size and help wrap the belt to prevent slipage.

Nobody should run as low as 2" on a 92/93 unless they're intercooled or water-injected. It'll actually kill power. Way too extreme, even for my setup.

On your Jet, I heard that they didn't make a chip for the 92 SSEi? Or is that what the 'custom' was referring to? I know there are some other 92'* here that might be interested in that.

You may also want to switch to a gatorback belt in addition to that zzp idler. Just to make sure. The 2.2" pulley is dinky, and you need good belt wrap. You'll be running a similar setup to mine, and if your chip raises your redline to where mine is, with that smaller pulley, you'll be spinning that SC at over 16,000 rpm'* at redline.

Get that sucker flushed, too. And clean your TB.

Well jetchip'* website has a chip for 92 n/a'* and i emailed them asking them if it would work on my ssei and they said that it wouldnt but if i wanted to pay the extra they would program one for me so thats that. and if im getting the idler pulley do i still need to get the belt?

Get the idler pulley and the stock-length SC Gatorback belt. This page of pics will show you why:

Even with the ZZP idler, you still don't get a full 180° of belt wrap on that dinky pulley. The Gatorback will add some grip to help out with any slipping problems. You can see the Gatorbacks in those pics, as well as a comparison of the stock vs. ZZP idler. That'* the 2.2" pulley, too.

Thanks a bunch you guys are awesome, oh and i was wondering what kind of benefits the performance coupler gives? will it help with acceleration or what?

The coupler does nothing for performance. Think of it as a cushion between the pulley and the gears, so they don't get hammered when you stomp the loud pedal. If you get a rattle at idle, it needs to be changed. You will have to remove the SC from the lower intake to do this. On your car, if it'* the stock SC/nosedrive, it'll probably be soon if not now.
