Is there a large gain at all for a ported head and cams or more just raised powerband? Tried to search for this but couldn't find any good info.

 

depends on the who dose the port work and what cams you use as to how much you get and when you put in bigger cams the powerband changes

 

Was considering just exhaust porting to match the intake and stage one zzp cams. Although don't know if its really worth it when a bigger blower would produce better gains for now

 

exh porting dose a lot (you wont match intake in size or cfm) the zzp stg1 cams are ok the stg2 or 3 are a better choice or go custom from comp cams

 

I noticed significant gains with my zzp/comp stage 2 cams and ported head, on the m62 blower as well.

 

advise has stage 2 cams and a ported head with a tvs and his car hauls assss

 

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.

 

As a daily driver and driven often are the stage 2 going to be too aggressive or unreliable over stage 1? Never dealt with this kind of internal work yet

 

Stage 2 cams are fine for a daily driver.

 

you cant tell how aggressive a set of cams are just by looking at the specs the stg2 cams are easy to deal the car drives like its stock

 

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

 

I wouldent buy jack from them they have not proven themselves in the ecotec performance world and want way to much money money for what they sell that they have no proof it works lsjion is a better bang for your dollar

 

Yea I was talking with lsjion about porting and what not. Just trying to decide if upgrading cams and springs is worth it on a current intake exhaust only car. As in how it will affect drivability and performance. Long term tvs is what I want to do

 

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...

yea and you made big claims about an lsj head you did without proof

 

Yea that's what I figured its already off do it right first time. Think I need to do pistons or anything while its open? I don't want to have to pull motor. But don't wanna have a problem and then wish I had lol

 

It all depends on what you wanna do down the road. More than likely, you're gonnna have to rebuild it EVENTUALLY. Not saying it's gonna be the week after you put the head on, but let's face it, the engine isn't gonna last FOREVER. If you dont' wanna pull the engine, then don't worry about doing pistons. It's foolish to throw pistons in there and not set proper piston-to-wall clearance.

Throw the head/cams on it.. enjoy it.... get bored.... throw a TVS at it.. enjoy it more

 

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......

AMMFAB shop cavi engine rebuild

the goal has been met......... 519whp from the shop cavi

I would recommend LSJION over anyone when it comes to porting LSJ heads.

 

My doing it right the first time was in response tstone saying that while I was getting it ported mid as well do the cams and springs. Idk anything about your work so I wouldn't put down what I don't know

 

He was referring to MrB

 

well then i take back what i said and im sorry i jumped to conclusions there. u could see how i took it that way i hope.


tstone i would expect that u would go with jon as it seem like u know him based on what u said above, i would go with somebody i know too i suppose if i didnt do this myself.

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
