some input on my new engine

[Michel Paiement]

Im building a 2.3L stroker engine right now, having a hard time figuring out what intake manifold i want to go with, not sure whats really out  there aftermarket to work with my 2g head, but ive been reading about the evoIII intake manifolds, but cant find a useful post on it. My main thing is i want to keep my EGR setup.

My other thing is i have been thinking about going with forced performance 3065 ball bearing turbocharger, does anyone have any feed back on this turbo, with me having a stroker engine spooling a big turbo wont really be a problem for me. My goal is to hit 450 or 500 awhp.

As far an intake manifold, I would stick with a cleaned up ported stock 1g manifold. They don't look all that bad when cleaned up, and they work well. Talk to Lowell about that one. He's making almost 500whp on one without the midrange losses of a large plenum short runner manifold.


I don't think you'll have an issue making 450-500hp with an fp3065. I'm making that with a 2.0l with an fp3052. I'm assuming you're after quicker spool and low end tq by going with a stroker. If that's the case, I would go with an hta76. It's basically the same turbo as mine but flows an additional 5lbs/min. That'll hit your goals for sure without any unnecessary lag.

1g intake manifold won't work well with a 2g head 

besides aftermarket ones, the Evo3 intake is the best setup I would assume.

Yans right on the turbo tho.  a 3065 might be bigger than you need.

whoops!! overlooked the 2g head.  just ignore what i said

1G ported gasket matched and polished.
1G cyclone ported polished gasket mached.
and unknowen: kriss rizon showed me this nice intake that had no runners and a 5L plunum.


Head info aswell just for fun
1) 2gs no good rule them out,
2) evo runners are smaller as well. so its up to you with the evo .
3) 1G turbo head is good
4) 1G turbo head ported is better.
5) a 1G head stamped G6 or M6 " dont remeber what the letter was." that head with a larger casting. bigger better more bulk to work with went porting. gasket match port/polish and get 1mm oversized valves and a 3 angle valve job.

The over sized valves and nice fat runners helps the strokers breath. The stroker has the same time to intake the volume of a 2L as the 2.3L %15 (more not counting cams but even then it would still be %15 more when said and done.) there for Id go for a 1G ported, or a 1g g6 ported with over sized valves for best flow.

I think a stroked with 2g head will be killer. Get enough cfm under .40 Mach on the intake side and lots of movement on the exhaust side 

[Ivan Skare]

There have been arguments about what head is better.

There have been arguments about what head is better.

yea I wouldnt go as far as arguments. but their are alot of personal prefrances. its always nice when you have alot of choice and opinion. anyways good luck with your choices.

i have a spare evo III intake mani and TB if your interested chel,

[Matt Fredrikson]

I agree with getting oversides valves if that's in your budget,

As far as your Turbo goes, find one that will max itself out power wise for what you want to run. This is VERY important, there is no point in having a turbo that will flow enough air to get you to 650hp if you want 500. Now you need a bigger wastgate to stem creep, your not getting the Turbo up into its "sweet spot" and you have excessive lag. It will work but there is no need. On my car I picked a Turbo that was good for 400-450hp at best and ran that baby maxed out, were talking 26-28psi so I was getting every bit of potential out of my Turbo and still had it as small as possible.

My motto when it comes to picking a Turbo is not to get as big as you can but infact to get as small of a Turbo as you can while still hitting your power goals as you will have a much better power band to play with.

As far as I know you have 0 experience with a 2g head.

My main thing is i want to keep my EGR setup.

This can't be done with a 1g head.
People have made over 1000hp with a 2g head.
I can't help on the intake mani question as I have no experience with different ones.

I don't agree with keeping the EGR setup...
End up with a dirty intake and pistons which ultimately will add to knock issues.
I passed Aircare with my setup and no EGR...

[John Hartman]

if you are running pump gas, an EGR not only helps with aircare, but it helps with tip-in knock.  Race gas, yea who gives a shite about tip in knock.
