Just wanted to help some misguided people out, for those of us with the 2.4 and GM SC it is not smart to lower the compression since the GM SC can only get up to 10 PSI MAX. I made the mistake of pieceing together a motor like this and after all the hard work and tuning from 607 tuning I am going to be lucky to have a car in the 14s. Anyways it sucks to put tons of money and time into a motor that is just slow.
Learn from others, keep stock compression fellow GM SC 2.4s!
Okay thats it.

well, in my oppinion, and this is only my oppinion, if i built a motor and was dealing with higher compression, i would probably go turbo simply because the m45 is so limited...but thank you for the information
yeah I wouldn't think a 2.4 with higher flow than stock would be a good fit for the m45. Its too big stock really.. the m45 is a great fit for low boost on a stock motor. other than that grab a m62 or bigger if you want a roots setup. for high 13's its not bad though and reliable.
Sven you totally quarterloafed your computer..
go turbo or get nitrious!!

mines lowered to 9:0 and mines not a dog, i gained 2 tenths from my rebuild before the 2.6 pulley and injection, im also planning to tune for the 65 and 80 shot as well.
Chris, if I was you, I would spray the living SH*T out of that motor....lol. Just a suggestion.
that charger is junk if your looking for any type of respectable power.
turbo that pig.

lol i beg to differ, i bought the gm charger with very high hopes, knowing that your probally only going to dyno around 220whp with it and bolt ons so im also spraying the motor, right now i should be dynoing around 250whp untuned with the 35 shot, that powers pretty respectable for the 2.8 stock pulley and 35 shot if you ask me. i now have the 50 shot nozzle on the car with the 2.6 pulley so you know thats more than 250whp, well should be, i still have the 65 AND 80 shot to put on but that comes when i get HPT. you can make good power with the charger, all you need to do is have all possible bolt ons, headwork, 2.6 or 2.5 pulley and some spray, pretty simple.

And you would know a lot about respectable power? Do tell?
How much is respectable power to you?
well i laid down 400whp in february in my teg, and went 11s on 20 inch all motor slicks. with a curb weight of 2850 with me in it. and my 2 rims with street tires in the trunk i drove there on.
currently we have 3 motors in the works for our shop cars, mine will be around 500whp coreys will be around 400whp totally stock b18c on race gas and dales will be a low 10 second high 9 second SFWD crx with a 2 liter ls/vtec making in the neighborhood of 650whp.
so id say i know a little bit about building and driving a car with a solid amount of hp.
that gm supercharger is a waste of money, plain and simple
you can extract way more power out of a turbo kit you could build yourself for under 1000 dollars if you are resourceful.

doesnt sound very simple to me or cost effective for only 300ish whp. but different strokes for different folks i guess.
im curious, how much have you sunk into your car, ir headowrk, boltons nitrous, charger, ect ect.
a "totally stock" 400 horsepower b18c???? how can it be 400 horsepower when its totally stock, and stock they only made 190?????
welcome to honda my friend. guys are making 600 plus whp on totally stock motors.
its all in the tune. and race gas. and a nice big turbo hahah

i mean stock as in stock oem parts from valve cover to oil pan.

I realize the s/c is not a great power adder, it was designed to be a reliable kit with some added power, hence why gm built it..............so really....for the "I want a little more reliable power" person......The charger isnt a waste of money for them...
Yes everyone knows that if you want at least 250hp that turbo is the way to go....and this is where the charger would be a waste of money......
So is there ANYONE running stock compression forged pistons or higher compression pistons with the charger?????? Maybe I'llhave to be a guinea pig and give it a try?

Car is for Sale!Supercharger kit is for sale!
Yea thats what I am probably going to have to do down the road. I hate turbos, just dont like them. They are constantly breaking or needing to be rebuilt. I understand not all are like this but it seems like a lot of hassle for the turbo set ups to run for longevity.
I like the GM SC, when it was stock compression it was a nice 35-40HP kick in the ass, but I amd saying dont lower the compression. I am going to bump my compression to 10.0.1. I will keep my rods and just change out the pistons. It shouldnt be bad.
When it comes down to it, yes the GM SC is not a bad mod, I paid 2,000 for the kit which included Apexi SAFC 2, walbro pump, 320cc injectors, egr Sim and a ton of other stuff and sold off 500$ worth of stuff off it. I also got the kit over a year ago and no problems. So $1,500 for boost and fuel upgrades, that is not bad and try and do that with a turbo set up with a RELIABLE turbo, lol. I will never knock the GM SC, just cant lower compression is all.
For now I am picking up my car today from 607 Tuning, Jimmy99Z24 has done an excellent job turning my car into a stock running HP tuned vehicle. I cant wait for the first test drive. He used his G tech and pulled a 14.6 out of it all tuned with 17s and not pushing it too hard. If I can get a low 14 sec converitble down the track that runs like stock, that aint bad.
So anyways..... Dont lower compressionon the GM SC, lol.
Thanks

for 1500 i could build a turbo system that would outlast that roots type blower.
longevity is a byproduct of a proper build.
you half ass it, shell break on ya. simple as that
friend of mines gtp(3.2 pulley and tune) destroyed a susposedly built honda with a built motor , and a s/c
if you wanna talk imports do it else where , where someone cares
id rather have my s/c over a turbo , hence why there is 3 s/c powered cars in the drive way at home
cc if you wanna talk crap go else where
Now, I think you are just being coky, no offense but the GM SC is not that bad for someone who wants reliable HP gain. Since my car is a 98 I could not use the reflash, people with the reflash are running low 14s and high 13s, that is awesome. You can pick up the kit for under 2gs and be safe, no reason to knock it. I would like to see a turbo set up run for 90+ K on a J body like a few GM SCs have. Have half of the tuning issues and way better MPG.
But turbos are cool, so CCfab thats your strong point and good luck with them and keep making big power, I am sticking with the SC.
Either way the only car I would turbo is the new Cobalt, at nopi there was 4 of them running 6 and 7 esc times, awesome cars.

600+whp on a stock honda motor, what are you smoking.
Team GREEN
^^
Yea also 600WHP is bogus, there is a guy here in Roc witha well known 2000 honda civic SI with 440WHP (Been in 6 magazines, nice car) but it is built to the hill running 21PSI. He did 500 WHP with 110 octane, but no 600HP on stock internals. Then at NOPI nationals there were a buch of built hondas, turboed running 13s. Also isnt the new hondas (2000+) one of the hardest ones to turbo cheaply dues to a composite pistons? I know a few people who have newer Ludes and hondas and it is too damn expensive to run safe.
Also the Cobalts blew the doors off all of the hondas, lol. Best honda/dsm there was running high 8s.
The roots M45 requires no maintenance, its really not bad.... just dont lower compression, lol.

honestly i probally have about 6k into the car over the last 3 1/2 years ive had the car, i got the car for like 2 grand salvaged with a clean title and here i am. I know i could be making alot more power with another car (is300, srt-4, honda) but i decided since i got the car super cheap and i seen that nobodys really doing any big things with the gm s/c on a 2.4 id see what i could do, i mean theres only a handfull of guys on here thats doing things above normal on the gm s/c. the next project will be 2.2 ecotec with hahn stage 2 or the eco gm charger with a smaller pulley since they make alot more power than the 2.4 charger, either way the botom ends will stay stock since ive seen some great things outta the 2.2 eco's before they blew.
rebuild labor: $700 (got the works done to the 2.4)
rebuild parts: $2200
gm supercharger: $2300
boltons: 450ish (got exhaust for free since i custom bent it)
nitrous: $500 with 2 bottles
basically just wanted to see what i could get outta a cavalier, this is my first car so i think im doing damn good for starters, im gonna head to the track next week so hopefully this 2.6 pulley, injection and 50 shot will dip me in the low 13's if i can hook.
I have heard some funny @!#$ but 600 whp on a totally stock honda motor with a 'good tune" is near treason...
I guess I could get close to 400 whp on a good tune for ym ecotec, what do yuo guys think?
