Just installed GSC 272's 10.5 hotside ebay o2
 

Hey everyone i just got my car back today from Da Mar imports in milwaukee wisconsin great shop great people! Now on to the good stuff, i just had my gsc 272s installed along with a coated/ported 10.5 hotside and a coated ebay o2 housing. i will be getting a custom flash from AMS on March 21st. But for now all i can say is wow what a huge difference the car pulls so much harder up top, the car use to pull till like 5000 rpm then die off now it pulls to redline. The idle on the 272's is sooooooo close to stock so if anyone worrying about idle dont! I cant even really tell that it has cams. I will post my dyno sheets/numbers next week when i get my tune anyone wanna take a guess what ill hit on AMS dynojet? K im done.

who did the porting on your 10.5 hotside?

some local guy for 75 dollars, i didnt feel like sending it to buschur for 50 and pay shipping and waiting for it.

I'm basically going to same route as you minus the o2 housing. Hopefully to get on the dyno in a week or so.

Come on! The 272's idle with a lot of overlap.

I donno how your 272's idle like stock but mine are lopey as hell! I dont mind it though. They were by far the best mod ive done so far.

guess i should record my car then cause honestly it sounds just like stock. you guys have gsc v 2 cams?

Gsc's may run a little smoother thanks to the extra polishing on the lobes but I didn't think it'd make that much fo a difference.

ive heard hks, they are a bit more lopey
