Well i am new to boost and i just picked up a z24 with a 2.4 i want to boost it but is it worth to boost a auto? also if i do boost it how much would i need to beat a Cobalt SS? is there some kinda a check list i can use to know what parts i need to buy? i don't know if this is covered in this forum.
beating a SS shouldnt be that hard.. I mean it has like 205hp, and to the crank about 185hp ?
Get the electric shifter for the 4 speed auto and boost your car around 10psi..... and get some bolt ons like engine mounts, HO manifold, HO tb, a good set of sparc coil and sparc plugs and he will be done....
go check out every boost post and read everything on the internet about turbocharging b4 you go boosting also i suggest you clean the carbon out of your compression chamber, i was chasing my detonation problems for a month to find out that carbon build up was the problem Have fun

Nothing wrong with turbocharging a auto. You should b able to beat a SS with a well designed turbo system pushing only 5-6 psi.

cobalt ss..... aim higher my friend..... think corvette c5........ boost is your friend...........
realize with a turbo set up on a car NOT designed for turbo...... it is time consuming, money guzzling, and just an overall BITCH...... however the pay off is GREAT !!!!!!! I must admit turbo is really fun but you need a great tune.... without that bye bye #3 main bearing....

Bearings going out have nothing to do with tuning. They usually spin or seize from lack of oil pressure.

No its more like 220hp at the crank because the cobalt SS makes 200hp at the wheels
I've seen an ion redline make 200hp and like 190tq at the wheels with an intake and catback. My bf has video of it he'll post it in a few days when he can post again lol

^^^^^^^^^
COMPLETELY Correct......
however it was my understanding that if you run too rich.... if you tune too rich that it can leak down past the piston rings.... and get into the oil..... and thus spinning the bearing.... the likely hood of something of that nature happening ... not high but I though that was what kept happening....the pressure problem you stated I would figure would be a oil feed/return problem ???
Skilz ??? care to explain ??

i have seen videos of SS/Redlines making over 200hp around 190tq stock.

ok thanks for all the information now i got a few more questions
Can i have a turboed 2.4 for an almost every day car?
what psi should it be running for every day use?
i just really just want to keep up with a SS i don't really want to go any faster than that *i love speed i would get to many speeding tickets*
Will 19" rims screw with me if i get some? like if i take it to a track or should i just use the stock z rims? when i am there.

Iv'e never head of anyone running so rich they polluted their oil with fuel causing bearing failure. Before that would happen they would probably kill their piston rings and cylider walls from the excess fuel washing away all the oil.
I PMed you about my theory on oil return pressure problems since it has nothing really to do with this post.

Yes, you can drive a turbocharged 2.4 daily. Most daily driver guys run about 6-8psi. Wheel size doesn't really matter but heavier wheels will use more hp to spin in return slowing you down and taller tires will alter the gear ratio to the ground in return slowing down acceleration.

what books are good to read about turboing? i got the stupid Sport COmpact Performance book by Haynes but it really dosen't say any thing.
Read "Maximum Boost" by Corky Bell, its a great book.

Oil is a cushion between bearing and crank. As a cushion there is a limit to the amount of force it can support. Pushing the limit can cause bearing failures. You can push the limit with tuning in the following ways:
1) Excessive spark advance for the fuel type. Causes increased oil temperatures and possible repeated intermittent bearing + crank contact
2) Excessive oil temperatures from excess timing or lean fueling. Oil becomes too thin to support brg.
3) Fuel washdown. It doesn't take much, only about 20% gas in the oil on a poorly tuned car can cause a problem. It happens more than you think. Usually what happens is fuel washing reduces the life of the bearings instead of killing them instantly.
4) Lean fueling causing detonation and/ or oil heating.
Many people seem to lose #3 brg on the 2.4 engine. Do some planning to try and prevent this problem.
Build the car well and it will treat you well. Drive it appropriately and it will give years of good service.

see SKILZ..... #3 above...... I thought that was possible...... and I knew it didn't take that much......
I knew I heard it somewhere....... n e ways thats a good post above ^^^^^^^^^^^^^ exactly......

Best $40 I have ever spent. While a little outdated, it still captures the basic concepts of a good turbo system that will never change. I think he should release a new edition.
I was a retard, and now I'm permanently banned.

beating a cobalt ss shouldnt be that hard... the best i have been able to get out of mine is 14.4 with only a filter which is faster than what i have seen other ppl running on a average i see 14.7-15.0 from ppl on cobaltss.net
but good ppl to talk to would be skillz, has a built motor but pulled a 13.7 @6psi, dragracemyz24 has a good working auto as well, and shownglow although i havent seen him forever was running 13.9's in an auto with stock internals
ppl you shouldnt listen to has a 3 letter name
