NEW 22RE performance cylinder heads

putneysmachine · 10-12-2009, 01:33 PM

Hey yotatech kids,

We are a machine shop that specializes in Toyota 22RE / 22R engine machining and rebuilding. Besides stock rebuilt engines and heads, we also machine and build performance cylinder heads for the 22RE.

OUR PERFORMANCE HEAD:
We start with a NEW cylinder head casting. Even though it is a new casting, we re-surface it (we have yet to find ANY casting that is perfectly flat, including OEM Toyota). We then remove the exhaust valve seats and install HARDER powdered metal seats for longevity using our Serdi 3.0 valve seat machine for precision. Then we cut ALL intake and exhaust seats with a 3-angle (30-45-60 degree) cut to match the FERREA 1mm oversize stainless steel valves made especially for us.
We have inspected other manufacturers stainless steel valves, and have found very poor quality all around. We contacted Ferrea's engineering department and have custom SS oversized valves made for us. The design was flow tested for countless hours and we (and our customers) have been very happy with the results.
We then hand machine the ports on the cylinder head to take full advantage of the oversized valves.
The valves are installed and machined for proper installed stem height. We install steel clad Viton valve stem seals and LC Engineering performance valve springs.

We install a 280-440 EFI (we also grind our performance cams for carb apps as well) cam for ALL-AROUND performance. We only use reground OEM cams for our shop. We have yet to find an aftermarket NEW cam that is made of hard enough material to last. We've inspected most on the market and found them sadly made of material / hardening that is too soft to last more than a few thousand miles.

Normally this head is sold for $765.00. For yotatech readers we are offering it for $650.00 (plus $30.00 UPS shipping in the lower 48).

We also highly recommend a reman rocker assembly for $175.00 (towers are cleaned and glass beaded, new chromed / harder higher oiling capacity rocker shafts and refaced OEM rocker arms and new adjuster screws).

IF you have any questions for us about ANY of the parts we use (or DON'T use) feel free to shoot us a mail or call us directly. We are happy to explain whey we are better.....

Gee, sounds interesting.

Got a few questions if you don't mind.

Which manufacturer flow bench did you use to flow test? What components did you test? What was the % increase in CFM from your base for each component? What base (specs) did you start with?

What are the cam specs for your 280-440 camshaft?

Who's "on the market" camshafts have you "inspected and found them sadly made of material / hardening that is too soft to last more than a few thousand miles."??

Have you done any certified dyno testing of this head/camshaft? What were the results?

Thank you.

Hey gNarls,

Thanks for the questions, I'm always happy to see that people actually read posts!

As far as the flow bench, we used an AUDIE flow bench in our shop. For the design of the valves we use, we let Ferrea do the testing and development of the 1mm oversized valves. We are currently having a newer and higher capacity flow bench built for us that is computer controlled and will have the capability for printing out the before and after results. I cannot quote you before and after numbers Ferrea gave me since I have not verified them myself.
I'd love to spout the numbers that my customers have given me after wheel dyno runs. Then again, until I have my eyeballs on it, I'll never say that is what you'll get. Fuel system, quality of the fuel used, the state of engine tune, the exhaust system...etc are all factors in the numbers people get. It wouldn't be fair to you (or me!) to give you hard numbers.

The specs for the cam are:
280 degree advertised duration
.440" valve lift
110 degree lobe separation
lift at .050" is .230"

When it comes to the brand names or the companies that sell them, I won't say. Throughout the years, we've bought and tested a bunch of different brands / manufacturers NEW performance cams hoping we'd find one that met our criteria. ALL of the new cams that came from Chinese manufacturers were always wayyyyy too soft (verified by our camshaft grinder). It's not my place to slag on a specific company or brand about the quality of their parts suppliers. I'm also not saying that EVERY new cam is bad. I'll say that I've seen a lot of inferior stuff sold to people. What we have tested does not meet our specs, I'll leave it at that.
We choose to regrind OEM cams to our specs.

Our reputation and name are on every part we machine and sell. We will not sacrifice quality for ANY REASON.
We are 22RE nerds, it is our #1 selling engine. We build everything according to our overly silly quality standards.
We may be a few bucks more than the others, but there is a reason.

Feel free to let me know if I didn't answer any of your questions....
I'll be happy answer.
Jerry

Hi Jerry thank you for your kind reply.

Can you give me the duration at .050"?

Is the valve lift .440 for INT and EXH?

What is the valve lash that you recommend for this cam?

I assume this is a single pattern lobe?

Will this cam work in a stock 22RE?

Any problems with emissions testing and passing?

Thank again for your help.

Duration at .050" is 230

Yes it is 440 at intake and exhaust

We adjust the valves at .008" intake and .010" exhaust, after initial start and run for 500 miles, we recommend readjusting since the Parkerizing on the cam wears off.

yep, single pattern lobes

This cam was made to get the most out of the stock EFI system. The idle is smooth and there are no other mods needed. We do have other, more aggressive cams for upgraded fuel systems too.

Will pass emissions test without a problem.

Let me know if you have any other questions.....

Jerry
