supercharge question. anyone?
 

do you really need a heat exchanger to supercharge a 2.2, yea i know the cooler it is the better. but is that optional? thanks for any response

The gm sc kit for the cavaliers come with no intercooling system and they warranty it
Ull be fine but still would get an heat exchanger system though

You don't need it, but why not run it? The manifold has it setup already for intercooling, it's not like you are going to have to add extra parts under the blower like some applications.

If you don't run a heat exchanger you probably shouldn't go lower than a stock pulley because the heat will go up too fast.

agreed^

hmmm thanks for the info, now i gotta trade this 2.7 pulley for a stock pulley.

Just run a HE, not like its terribly hard to install/expensive

yea i know i should, but im impatient when it comes to boosting, and piecing up parts and looking through ur parts list is just a big tease

so you want to half ass it?

better to use one a know you're safe then not and worry about breaking crap. pay to play

ehh not half ass it, im just narrowing down parts that can be put on after the installation when i got more money. 1300 for parts- nomoney= desperate

run the heat exchanger. its useless without it. even on a stock pulley. thats why the lsj had heat exchangers stock. you're going to have to block off the intake manifold to make it air tight(if you take out the laminovas). or leave them in and risk damage to them from the heat and not having any coolant run through them. also you WILL have to tune the car once the setup is on. and without the heat exchanger you will be running way too hot to pull any kind of timing and will only see a small hp increase over stock. then when you do get a heat exchanger you'll just spend more time reversing what you did to rig it to work the first time and then more money to have it tuned again.

stop half assing it, drive it the way it is now, save up your money, and do it right the first time.

ever herd of knock retard?

thanksss.

Just do it the right way out of the box. I'm running a dual pass/opt b from the start so its less I have to worry about later on down the line. Thinking about even getting one of those ZZP spacers

where and how much did u get ur h/e for?

I'll take the 2.7 if it is a 4 bolt.........:)

ill let u know if its 4 bolts when i get home

Dont bother putting it on without a heat exchanger... Its cheap and you wont have IAT2's like me lol.

I basically dont bother going into boost ever since its no fun anyways.

Someone i know had their pump stop working and he was seeing 190* IATs:lol:

You're not gonna wanna run that 2.7 even with a heat exchanger on stock 2.2 internals. Shit will go boom running that small a pulley

I see on average not touching boost 170's and thats when ambient is 60-70 and if im on it ive reached as high as 195.....

Ive got my intercooling stuff sitting here...must do it asap!

Lowest id go with ll cooling mods and a good tune is 3.0 pulley. Thats what ill be going to shortly once I get my supporting mods done.

Bought a 2.8:)

ahh sorry bro, its a 5 bold pulley

Braver than me lol. I'm probably gonna run a 2.8 after I install my rods and pistons in a couple weeks
