Thermostat is $8-$15, the intake just depends on where you get it. Check with the vendors down in the vendor section:

I am not sure on the prices--just visit their website. I think they run around $200 or so.

If you buy a like a ..... honda civics intake tube and filter it will run ya about $50-80 dollars and you will have to sightly modify it, drill a hole for your IAT, also known as a MAT sensor, and plug up a vaccum hole on the pipe. not hard at all and will save ya a $150

Noiyce man! I got a 92 Bonnie too.

i cant believe u just called a 3800 a peice of crap. what u think it was vette. i got a 92 buick le sabre (cousin of ur car) and i love it yeah its no benz or vette but hey its better then some honda, isnt it?

I hate to argue with a "moderator" BUT I MUST! You're wrong I'm afraid! You CAN SC a NA engine. All you need is some select parts & of coarse $$$$$! I've done alot of reasearch on the 92 SE NA EGRless engine & the 92 SE in general too. "NOT" or "CAN'T BE DONE" should never be used when it comes to "PERFORMANCE" If that was true, none of us here would never modifiy our cars because there is no one to sell the parts for Bonnevilles! Well some of now do sell performance parts for Bonnevilles now (Ty, Hector & Myself too) for just starters. Take Turtle'* Car! You tell me that can't be done? How about Scott'* bad *** Bonneville too? I think & know it can be done, they have proven it already! No offense is intended here or directed toward any single member, but, always remember "DREAMS" are what makes the next "PERFORMANCE MOD", not negative attitudes.

As for more info on just what is needed to modify the 92 SE, you can email if you wish below.

Lol rat, good post... his passion

I think what the moderator meant was that it isnt really practical for an average driver with average means to SC a NA engine.

PS I hate to be pickin about people posting but double negatives are a bit confusing. "none of us here would never "

If you want a SC Bonne.. Just go buy a engine trans COmputer and wiring harness out of a SC series one car and plop it all in your car . it would be less then moding your engine to be able to run SC . This is the route I might take and if you want you can to

thats alot of money though I thought they made superchargers for pontiac'* or am I completely wrong??

Will wasn't using his "Soap Box", so I thought I would instead.....
Sorry about the double negatives too.

Well frankly, Horse Power doesn't come cheap. But Pontiac does supply a SC for some of it'* engines, but, you just can't slap one on & expect it to last longer than the intial start up (if it starts at all that is). :? You need to make the engine & trans compatable first. Such things like: low compression pistons, larger throttle body, larger fuel injectors, EPROM, gaskets & seals, wastegate, lower intake, etc....
