I am looking into buying an LS2 powered car and I want to know what kind of options are out there and what resources are good places to start if I want to do some upgrades to an LS2. I drove in a friend’s car today who traps 101 in the 1/8th and makes 500+ rwhp all motor. Any input from the domestic crew would be appreciated.

if you wanna do a cheap all motor/nitrous build slap on some l92’s with a decent sized cam and that will put you at around 540 at the motor. now spray it with a 100 shot and you my friend will have fun breaking your rear end.

exactly. it’s cheap and you cannot beat the bang for the buck. that motor made 548 at the motr. not too shabby. figure on about 475-485 to the wheels then. now whack it with a 100 or 150 shot and you have a cheap build that makes fantastic power and is sure to keep you happy for sometime.

im a LSx n00b, but it seems to me that the lsx motors really see some gains from long tube headers, heads, cam and a tune. not sure what the longtubes run for the car in mind, but i know they are crazy expensive for my GTO but everyone says they are well worth it, so I would start there and do a full exhaust and then get into a cam and heads, etc.

i dind’t. but the heads can be head for about $375/piece. these are fully assembled with valves/springs. You will need an l76 intake if you do this which isn’t too expensive and already has a 90mm opening in it. The fbod guys sell the 90mm tb that comes with the intake since it’s DBW. the cam will run between 275- 450. depends on what monster you want to put in it. with a cam you may need to upgrade the springs ($200)on the l92 heads. pushrods are a must($125-150). Radnom gaskets and such. All in all less than $3,000 in mods to make over 600 hp seems like a steal to me.  
As for the GTO boy. yes intake/exhaust are great mods and the LSx motors respond well to it. Obviously you don’t want to go throwing heads and a cam at something while running the stock mani’s (though they don’t flow nearly as bad as they are made out to). We all know an engine is a big air pump so air in and air out = best results. Longtubes are going to vary in cost dramatically depending on the brand. Kook’s, QTP, Hooker, Hedmann, SLP…etc. Lt’s are usually starting around the $350 area and work up to about $1300. Then you have to decide on keeping the cats or letting em go. If gone you’ll need a y-pipe. Then of course a sexy cat back to bring the mean sound all together. Don’t rule out the shorties either as they make good torque just don’t gain as much on the topend. Shorties + cats = deep throaty growl. LT’s + catless = loud noises.  
any other questions? :lol: sorry so long.

Those new heads rock…you can throw together a real nice 40X LSx motor for a lot cheaper now.

Don’t you need an LS2 or _\>_ a 4.0" bore to run those heads? Meaning they won’t fit the LS1 due to the fact that the cumbustion Chambers are too big for a 3.90 bore??

After driving in what I deemed to be a great sleeper and DD, I am thinking of trading in the STI for a new daily in the Spring and I want to figure out what the best mod/tuning path would be for ~500whp.

500 whp will require an aggressive cam and head combo with Fast 90/90 and full bolt ons (good ones) . Or , a procharger, turbo kit, or nitrous with bolt ons will get you there as well and most likely past that . If you want to talk more about it feel free to give me a call 585-865-1832 and I can try to answer more questions for you .
