billet s262, 443whp on 20psi 91octane, no meth, unported head. :p::p:

just wait till i get the batmowheel on there. or even just the 198s still on the billet wheel. hahah. the only reason i'm not in the 500s on pump and 700s on 110 is the injectors

It was also basically stock. Diamond pistons, arp studs, that's it :) revving to 7200rpm. Just saying they are heard of ;)

EXsoccer1921 08-16-2011 09:35 PM

well duh, over stock it definitely makes a difference. but over a ported head on stock cams?? definitely not

Who said anything about ported head. The most I have made so far was 438 on a complete stock long block with a lifter and rocker blown apart. So I was only running 3 valve on #2. The only reason I run meth is for the lower iats and safety. I'm only on 17* timing.

EXsoccer1921 08-16-2011 10:19 PM

well then go dyno again now that you got all 4 valves and run some more timing.

RedSSbalt246 08-16-2011 10:27 PM

I cant wait to do my swap. I know it will be worth it. All i hear is good news lol

EXsoccer1921 08-16-2011 10:29 PM

if by good news you mean open wastegate, then yes thats all you'll hear

jonathan923 08-16-2011 11:18 PM

lmao^^^^ HEY!!! am internal wastegate :( i like it though :)

Boosted05 08-17-2011 01:54 AM

I would go turbo if I had the money, but I think i'd push the limits of a S/C first. Plus cops round here hear a BOV or spooling they are on you like stink on shit..... now for some reason they don't give a shit about the blower. odd. They used to love my old 2G GSX with big front mount, and greddy BOV, and open dump.

jonathan923 08-17-2011 02:20 AM

IMO it takes alot of work, time, and more money to really get to max 300whp on an m62. With turbo the least your will make is between 315-330whp just to start. then its just a matter of turning up the boost and some tunning and done. :) so i think its just better to save up the money and go for it, i mean its everyones choice unless you really like the blower..

startingline05 08-17-2011 12:25 PM

lol remember the days when you were the shit if you had a 2.8 or lower pulley and 60's on a m62 and running meth?????

jonathan923 08-17-2011 03:01 PM

hahaha i rememeber when the gms2 on the lsjs where moppin everything up lol. even srt4s and everyone respected cobalts after that haha.

harryresh 08-17-2011 04:20 PM

what alternator, tensioner, and belt do i need for my turbo swap? im keeping my A/C.

i happen to already have a tensioner from a 2.4.

i see ZZP sells a turbo swap kit for this belt drive assembly swap but i could prob get the shit cheaper separate and get a core charge for my original alternator

EXsoccer1921 08-17-2011 04:26 PM

the 2.2/2.4 belt, alternator, and tensioner. or get an idler pulley in place of the stock blower pulley

05Slowline 08-17-2011 04:37 PM

trust me you're better off buying the zzp kits there's so many little things included only reason i didnt get the kit is the cp would be diff on my car lol

jonathan923 08-17-2011 09:04 PM

am using the 2.4 tensioner, 2.2 belt and stock alternator just welded lol :) works good for me

Boosted05 08-17-2011 09:27 PM

If i'm in a position to drop 3k or more on a turbo swap i will. In the mean time I'll be picking up the little odds and ends to go for 300hp. I have a 2.7 already, highflow DP, and header. Just need 80's, gauges, and a good dyno tune. I'm dealing with a fail dealership over getting my simple motor swap done right, so a ZZP s2 may be in the works paid for by insurance.

selfinfliction 08-17-2011 10:05 PM

shit i'mma put a 5.8L blower on mines car and wooo wooo past you!

mexi_loco 08-17-2011 10:25 PM

-Vibrant 3" Cat-back exhaust

Custom Parts (fabricated by Kratos Koncepts):

This doesn't include the guages I had to buy b/c I was a douche and didn't prepare properly. Here's my "build" thread:

https://www.cobaltss.net/forums/2-0l...-story-240486/

Problems:

(1) First problem came when I started with the wrong parts. I bought a HAHN turbo manifold (beautiful piece of artwork) that ended up being for a 2.2 j-body ecotec. FUUUUUUUUUU. That was a real hit to the nuts. Had to order a part from ZZP (along with some misc. stuff) while it was on backorder. EFIN FUUUUUUUUUUUUU. Had to sell the beautiful manifold to some wet-back in Mexico City just to get my money back. Double-EFFIN FUUUUUUUUUUUUU.....

(2) Next came the dreaded fuel pump recall...my car had it, but for some reason my car's VIN was not part of the recall. FUUUUUUUUU. Thankfully, my crafty buddy at Kratos Koncepts jerry rigged something that works perfectly.

(3) Then came the issue with the replacement throttlebody bolts I bought. They weren't from GM, so as we were tuning, I went WOT and some how two of the bolts were chilling in my wheel well. Created one interesting lean condition....FUUUUUUUUUUU.

(4) Now I'm dealing with a smoking issue...but thanks to rob (usmcp), I'm reworking my pcv system so that I can hopefully get the issue resolved. Otherwise, I will need a restrictor and fix it that way. Either way, this problem plus problem no. 3 means that all tuning is at a stand still.

Anywho, I will be installing a boost controller as well during the down time.

Future Plans:

Internal work (pistons, rods, maybe port the head, or just buy one and build it) and crank the boost to over 25psi. Then after I run that sum-bitch down, I might switch over to a BW...but that's a wish list that comes with everything else (engine and then some).


Pics, vids, and other shit can be found in my "build" thread. Or you can just friend me on FB and you'll see my photography there.
