Here is a repost from another forum.

I have contacted the maker and the price is 475.00 fitted with your choice of throttle body. I have Q45 TB ready to go!

THANKS JEFF!


This is Jeff's Post:

About a year ago I received an unsolicited email from Leen Steed, [email protected], owner of SteedSpeed.com. Leen was asking if I knew anyone who would be interested in 22RE turbo exhaust manifolds, and sent me a link to some pictures of his work. His manifolds looked great, and while I didn't need one myself I said I would forward his info on to the the 22RTE-Trucks email list.

However, in looking through his pictures I also noticed an amazing custom 20R EFI manifold on a Celica Leen had prepped for racing:

It was almost a perfect mix of function and eye candy, exactly the sort of thing I have a weakness for. (And I won't even mention the crazy twin turbo setup he has on that thing ) I wanted one of those intakes...but Leen said it had some quirks, and Leen was convinced he could do a better job and build one that was a bit easier to package/fit under the hood. And thus began a long, extended conversation about bringing an improved intake manifold/plenum to the 22RE/RTE.

After a few false starts, Leen hit upon a design that retained the stock lower intake manifold while, which has straight runners with large cross sections, and ditched the restrictive upper plenum. His design also incorporated some generous built-in velocity stacks, to help the incoming make that hard turn into the lower manifold:










This past weekend, I finally got a chance to install Leen's latest prototype, and I think he has a design that's ready for prime-time:



I just got it installed last night, so I have yet to get it on the dyno, but I felt solid performance gains above 4k rpm, and significant gains above 5k rpm; obviously, the biggest gains are going to be found when the engine is moving the most air. And I saw no loss of low- or mid-range power, which was something I feared.

Installation was fairly straightforward, with the exceptions that a) i had to relocate the fuel pressure regulator to the front end of the fuel rail, as the manifold could not be installed with the FPR in its stock location; and b) I am not running the stock EFI, so my system probably represents the simplest case for installation, as I only have to account for one sensor and have remote mounted all of my vacuum hoses to a separate vacuum manifold on the firewall. And c) no, this isn't CARB-approved/smog-legal.



Unanswered questions: will this work or can this be adapted to work on a 22RE with stock EFI? Will this yield any performance gains on a 22RE? How much will this cost?

My best guesses are that you could probably adapt this to a 22RE, but it's going to be a lot of work. I am not sure if the performance gains are worth the effort on a non-turbo motor, as there are other, easier things you can do that will yield more bang-for-the-buck. Remember, this sort of manifold gives the best results when you have over-stuffed your stock manifold with air; this is rarely the case on a normally aspirated 22RE. However on a turbo motor -- specifically, on my turbo motor - it works very, very well. I'll post some more details after I get it dyno'd in a few weeks.

I don't know what Leen's price on these will be. If you are interested, contact him. Again, this is not exactly a bolt-on, but it is pretty damn cool, which is why I'm posting this. After all, very few people are actively developing new performance parts for these motors.

Thanks for the info. Very interesting.
