After 3-4 years of running the typical 2.8/60's setup, I wanted more reliable power. Power with this setup dyno'd 270whp and 250wtq. ZZP LTH, 2.8/60s/cooling mods, 3" intake, 2.5" exhaust, area47 tune, gmpp clutch w/fidanza flywheel.



After months and months of sourcing/collecting parts, I sent a bare head to Euthanasia to have the exhaust side ported/gasket matched. Sent him COMP/ZZP S2 Cams, Supertech 75# Valve Springs, stock valves, and he also hot tanked, decked, and assembled everything for me. I picked up a ported LSJ IM while I was at it from zrated which was also installed.

Finally got everything installed over the weekend as well as 80# injectors. Converted to e85 too.

Parts pile


Blower was the first to come out, all 4 SC bolts decided to strip as well which was fun.


Removed IM and valve cover next


First time the valve cover has been off the car, it was very clean for 76k miles.




Off with the timing cover



And off with the stock head. We got lucky and were able to wiggle the ZZP LTH off without having to remove it.



More to come next post

 

Cylinders looked great!


Euthanasia's port job, came out beautifully





Old head to compare

 

Cleaned the block:

Nea head installed:


Time to time it!




MANPOWER! Thanks to Vaughn (Japeatr) for all the help.


We are still working on the tune, and dyno will come shortly thereafter.

 

Total time spent - about 16hrs + tuning. Install went smooth with no issues whatsoever

 

Awesome stuff man!!

 

that'll be a nice increase in power. especially with the ethanol.

 

Sweet! In for more vids and numbers!

 

sick, in for numbers

 

subd looks great!in for results

 

I hope so, trying to see what I can push out of the girly m62 before I upgrade. May pulley down to a 2.6 or 2.7 depending on what numbers I hit.

 

With the head and cam choice you won't be on the M62 for long.

 

If I can be in the low 300whp range, I will be perfectly content with that for the time being. Upgraded blower will come soon, but balancing the cobalt with my other project car took away all my funds.

 

What do u plan to spin the motor to?

 

7800 is the plan.

 

those pics turned out well

glad to see my manpower shirt made the cameo!

 

No doubt! It definitely made the cut. I have 75 pictures total.

 

getting the timing nailed with the new cams was fun, no snags and just need some time on the tune and it will be rockin

 

You are the cobalt ninja

 

In for some numbers. I'm currently working on getting my head back together after my pnp. I'm debating on camming it or not.

 

I cant believe those are from your phone! Pics turned out pretty good

 

He must own the S3. Lol

 

All the pics in my thread r from my phone..
