Hi all - Welcome back for the second time this month!

I apologize for the inconvenience of the site being offline. The site was down for technical reasons, but it didn't help that I was of offline for two weeks (camping and travel). Once I got back, it took a while to get things sorted out. That's resolved, and the site is now back up. Huzzah!

Please take a minute and read the Site News thread I've posted in the General section, and feel free to comment. Thanks!

How much boost are you running?

You may need more cam, higher duration to move power band to right.

LC use to have a stage 3 turbo cam with more duration and higher lift than your current one that went along with the stage 3 head. Looks like they revised their cam selection and part numbers.




Hey I'm running about 9lbs of boost. The reason why I went with this can is because I wasn't planning on notching my Pistons. I was jus gona buy the hyper Pistons with stock bore. I know in the future though that I will be forging the piston and rods so ill be buying that stage 3 later but for now I'm jus gona deal with what I got.

"I'll probly go for the lc forged piston and rod set which runs about $985 and I think the rods are on sale so minus $45"

Have you or anyone here ever looked at Icon forged pistons? These might be a cheaper alternative. I am considering this with LC's new rods. Will save about $300.

Nvr seen or heard of these piston but I'm also curious on them.

Oh and also I was looking at those piston set and I think it's kinda of to low of compression for what I was looking for. I think it's 7.5-1 I'm looking for more like 8.5-1

The resulting compression is dependent upon head volume.  What type of head is that compression calculated with?
Note, LC has a CNC setup for cutting the stock head - they can add volume (decrease compression) for a surprisingly reasonable cost.

Yeah, with my 22re head, I'm supposed to be at 8.5:1.  Still high enough to have a bit of pep off the line before boost kicks in.   But I'm at full boost around 2800 rpms in first, lower if I'm brake boosting.

i bought a stage 3 head from a fren that nvr used it so i sent it to lc to open up the chambers and swap the stage 3 cam for there street turbo cam.  not to sure how much it dropped my compression but i doubt that its in the 8's since my block is a 94 block

I'm not sure why the insert quote function isn't working but anyways....

You are right, the spec sheet indicated 7.5 CR for 60cc head. These pistons sit 0.142 below deck. So for a 56cc (is that the standard for 22re head??), the compression bumps up to 7.8 or so given a 0.040 thick gasket and standard sizing.

This nullifies my above statement and still wouldn't work for you.

Changing the intake manifold to a custom with shorter runners and large plenum would help in the higher rpms with the associated head work and a cam that lives in that region.

There is a custom intake manifold for our 22re presently on ebay. I can't link it because of my workplace but it is under 22r intake manifold.

I'd like to see that.  It's not coming up for me under "22r intake manifold"...

That's nice intake mani. It says that it's made for ford TB. It would make the engine bay look cleaner

It's also an awful lot of dough for what it is IMO.

What are the specs on your GT25 and when does it make full boost?

I'm making about 9lbs of boost. I think it could go more but I need to fine tune it
