I will be going this route with a buddy of mine who tunes Honda's here in Montreal.

Here's a quick video showing out it mates up to FACTORY catback position!

It would be nice to personally look at area under the curve more than just hearing about some peak numbers.

It would seem that a smaller displacement motor would naturally rev higher, so a smaller displacement head on a larger block would help that motor rev higher, but isn't it more about the block that will determine max rpms in this case and not the head? Shouldn't the larger stroke (higher piston speeds) determine the limit? If not, what is special about the K20A head? I'm a novice with understanding bench flowing heads or understanding fluid dynamics, but it seems that a head built for a smaller displacement motor would be restrictive at the top end if it was matted to a larger motor, even if it was designed to handle higher revs. If anything, a restricted/smaller head would make for more low end torque than allowing high flow for peak horsepower.

Am I completely off? Does the smaller head actually have better flow? If I remember correctly (it has been a while since I owned a MKIV Supra), the NA head flowed better than the TT head, but that may have been intentional to get the turbos spooling or something. Nevertheless, it demonstrates that a small head can outflow one for a larger or more powerful engine.

Looking good. What kind of hp level and power band was the header designed for? Are tube lengths optimized or is it more of a swap header?

Swap Header development is moving along! This is a 1 7/8" Runner 4 to 1 with 3" V Band merge collector. We will be selling the header along with a mid pipe that mates your existing cat back! It will have the standard factory size 2.5" 2 bolt flange to mate up to the majority of standard FRS/BRZ cat back systems with little or no modification. All 304 stainless, made right here in Maryland USA, no subbing out overseas or junk metal!

We are now stocked up on our K24 Engine mount kits. These mount are made for use with a K24 block and S2000 6 speed transmission. NO CUTTING THE TRANS TUNNEL! None, bolts up to factory mount bolt holes. We do not currently have a shifter solution for these but have already sold a couple sets to people who are fabbing them up. In stock on SwapYour86.com!

Stay Tuned for more!

Will you make a adapter for a intake manifold, or are you planning to run it with the F20 intake manifold,tb, etc ?



For everyone who is interested in this,

A adapter plate for the trans/motor will be needed
(adapter plate link) http://www.balladesports.com (they also have the flywheel for sale)
F2K clutch master flywheel
(flywheel link) http://www.clutchmasters.com/aluminu...eel-fw-k2f-al/


Also if you take a look at the Upper Radiator hose it will have very minimal room as its close to the firewall..will there be a fix for that ? maybe CNC a plate along with either AN fitting, or 90* welded on.




CORRECT me if im wrong on any of this information above


but overall still should be a fairly easy swap if you have fabrication skills.


Look forward to seeing a PNP for this.

There are options to fix this, here is one I can think of for now.

thanks, that might actually be perfect

We looked at a lot of FWD dyno graphs when trying to design it. So kind of yes to both, yes it is a swap header but yes we did try to optimize it both in runner size and length. It's big enough to flow some bigger HP (300+) and the runners should be conducive to higher RPM flow. But to be 100% honest, as we have not actually put one together yet, it is a best guess until we test.

will there be a FI setup soon ?

K-swapped and BOOSTED FRS with S2000 cluster. Looks sick.

He starts talking about the swap here:

Says he uses an AEM infinity ECU. No A/C, but has traction control. He doesn't mention ABS; I'm assuming it doesn't work. I also don't know if that's an AP1/AP2 cluster. AP2 clusters switched to CAN in 06.

I don't even see an ABS module or lines. Unless he relocated them and/or tucked them then he deleted the ABS.

something ill have to take a look at when im off work..


does he have a build thread on here ?
