Ported heads and cams
#7
I noticed a nice bump in power from my COMP Cams/ZZP S1 cams. I run an H62 blower. Not sure how they would be with the M62.
An exhaust ported head is one of the best mods you can do for our cars.
Listen to Mrb though. He has some nice custom ground cams.

i really think this would be a great setup.... comes with all new parts, cryotreated if you desire, supposed to be good for a daily driver which i dont doubt at all... not sure if those GMP parts are just stock replacement or actual performance replacement pats, same with the cams

Definitely go with a ZZP ported head. They will do you good. And yes you will notice a change. Powerband shifts, etc. But, as said, worth it. If you had an LNF, not so much. haha

Oh neato, you're from Ohio too! So is LSJION, and myself
But if you're gonna get the head ported and ****, you might as well do the cams and springs at the same time. They won't affect drivability at all. You'll also get quite a big gain from the head/cams on the M62, and even bigger when you go TVS.

clean up on the intake side with some pretty good work on the exhaust side will yield some decent gains. the power should be throughout the power band it, shouldnt really move ur power band any higher though unless u do cams. and theres another guy that does good work with affordable prices also.... heres a subaru intake port he recently did...

can u be more specific......
cause heres the numbers from my race l61 head...... where my race lsj was the same profile with slightly bigger exhaust ports so i said it was probably about 5cfm more or so. so where do i not have proof beside the 5 cfm guesstimate i made on the exhaust side?
intake......
.050"- 68.1cfm
.100"- 107.4 cfm
.150"- 143.3 cfm
.200"- 186.4 cfm
.250"- 226.1 cfm
.300"- 251.7 cfm
.350"- 273.3 cfm
.400"- 284.1 cfm
.450"- 293.0 cfm
.500"- 299.1 cfm
exhaust......... percentage of exhaust to intake at given lifts.......
.050"- 53.0 cfm 77.8%
.100"- 88.4 cfm 82.3%
.150"-124.0 cfm 86.5%
.200"- 154.4 cfm 82.8%
.250"- 175.2 cfm 77.5%
.300"- 189.7 cfm 75.4%
.350"- 198.1 cfm 72.5%
.400"- 202.5 cfm 71.3%
.450"- 205.8 cfm 70.2%
.500"- 208.2 cfm 69.6%
OP u get a professionally ported head if i do the work. read up on me before u jump on a band wagon and put me down by saying it wouldnt be done properly.
and lets not forget what that l61 head went on, the stock block recorder holder mr. B......

I am buddies with him. But that has nothing to do with it. If he did **** work, I wouldn't recommend him. The work he does is top notch. He spends countless hours doing heads. He won't return a head to you until he is satisfied with it.
(that kind of sounds bad).. what I meant was, he makes sure his work is as good as it gets before it leaves his hands
