They'll work, but how good of a deal did you find?
08-09-2012
Kinda pointless though because these are for engines seeing well over 8k which your gp will never in its dreams see

True I am building a turbo GT, with a bottom end bored over 30
08-09-2012
Why no stock bottem end?
08-09-2012
Lol man why the **** would you waste the money? The blocks are thin enough. Stock engine with turbo. You mess with the bottom end you are asking for trouble
08-09-2012
The lifters would only set me back 50 bucks, the bottom end was rebuilt and bored over a few years back. The only think I want to do to the bottom is lifters and single roller( If beneficial)
08-09-2012
Bottom end fully assembled?
08-09-2012
Yes it is.
08-09-2012
Go for it then..

I mean will they affect performance in a bad way? Will they perform pretty much like stock but better at high rpms?

the lifters arent going to be your holdup with high rpm oiling, its going to be the little baby oil passages in the block.
i would just use a stock set of lifters, you're never ever going to rev your car past like 7000 anyway.

What nick just said ^^ if the shop that bored out that block knew anything, it would have been to open up the oil galleys from the tiny ass holes they come with from the factory.
Those lifters will want too much, and the block wont be able to assist them....therefore, you could be looking at a big problem down the road.
This is a 3800, not a cts-v race car that spins at 8k+ with just about 1/2" oil galleys.
I never thought i would have to bring these out again
but here goes nothing
08-10-2012
this is the oil passage in your oil filter neck....
Could you see the problem???? lemme help you
Those weren't even the oil galleys, the oil galleys are the holes that feed the mains and allow the crankcase to be properly oiled..Boring it out without taking these into consideration can result in very bad results in some cases.

Got ya.... so even though the LS7 lifters are a tad more you wouldnt invest in them for a turbo build?
08-10-2012
No we are saying buy regular ls7 lifters. Not racekar lifters
