I have made a set of RB25 to RB26 Intake/Plenum conversion adaptor plates.

Since i have the mold, i might be able to get it below $400 for the plates if i get the sufficient quatities. I paid $400 to have the plates cut.

The adaptor plates are made in such way where cylinder heads dont have to welded.

The only thing needed to be modify is the water outlet, either to cut and weld the water outlet or run the head with no VTC. Im running mine without VTC, so i have no issues with it.

PM me if anyone is interested.

Hmmm ..... although I am in the process of welding my spare 25 Neo head I won't mind getting a set for my standard running ER34 head and have next to no downtime. The only problem is that I live in Trinidad in the West Indies. Get me a price shipped over here, my postal code is TT. Cheers.

Jason.

Will post the pics up once the plenum is installed.

Think it would be better for buyers to have a look at the pics before getting the plates.

Dont want any returns and having those plates not fitting.

Cheers!

Latest pics of the adaptor plates for RB26DETT throttle & plenum conversion.

Let me know if anyone is interested with the adaptor plates.

It fits perfectly into the engine bay.

You will need to cut and weld your stock RB25 water pipe in order to fit the hoses in.

Besides that everything is a breeze.

Sorry for the last pic. Will upload something better once the car is ready.

I will have to speak to my machine shop.

Hope to get it below $500 mark. Will get back with a price

You will need to purchase new sets of injectors.

R34 GTT injectors will suit this conversion.

R34 GTT injectors will suit this conversion.

looks the goods. so u need to use to[p feed injectrs for these? i heard the angle for the injectrs is wrong if u go this way ? thats wat i heard .. maybe wrong... otherwise im very interested.

cheers

Engine started and everything is goin on well..

Very nice sound from the throttle indeed.

I manage to speak to my machinist last saturday and the best he can do is $600. I will include 2 pieces of stainless steel gaskets, allen key bolts and shipping to anywhere in Australia.

I have a set of Sard fuel injectors as well for the conversion. Everything for $1,700.00 w/shipping.

i'm new with all this atm.. but what is the advantage of doin this ??

seems to be very pricey plus to purchase a 26 plenum

in the end you would be able to purchase a greddy item, or hypertuned plenum

coz i'm stuck atm... need a plenum to get this conversion goin :P

    • So, the other thing I've sorted is a baseline dyno run up at Unigroup's new location. The auto trans was a little unco-operative by both shifting down when the throttle was floored on the dyno (so Mark had to ramp it up more slowly than in a manual) and also by shifting up at 6,000 even in sports mode instead of the indicated redline of 7,000 Still, on a hot day it made 240rwkw at 16psi which seems about right for 300kw (400hp) through an auto at the wheels.  The shape of the curve is not quite right because it was not full throttle to about 4,500 to stop it kicking down, but until I can get a tune on the auto trans control this was the best we could do.....full boost will be well below 5,000 once that is sorted, I'll get some data logs when I can to confirm For comparison, the R32 made 255 at 12psi (at 4,500) on the same dyno with tune, n1 turbos, cam gears, big exhaust but otherwise all standard so the v37 is likely a little better out of the box. One thing that is very clear is that the standard water to air intercoolers are not up to sustained use at full throttle in warm ambient temps. After about 5 runs (so only a few minutes full throttle), it was pulling boost and timing and dropping 10-15% power. Unfortunately I didn't get that printout and the Unigroup guys are away at the moment, will try and get hold of it on their return. So, looks like a healthy engine to start modifying and the only real area of concern is the w2a heat exchangers which the aftermarket has plenty of solutions for    
    • I maintain it actually looked really nice in person. So much so that I thought "No, this is illegal" but there it was, clear as day. I think we can easily call the wing and wheels/height to be transformative. Not saying it's better than the GR Whatever, or the 86, or the WRX STI or anything of that sort (the internet says it all bolts up so you can buy best of all worlds?) but it's still at least a thing and not nearly AS bad as people say.
    • That's less offensive than the previous gen.....except for all that ugly black tupperware around the edges. Blerck!
    • I leant out the window recently and took a picture of this new WRX. It looked real damn fine in person. It's faster around a track (stock) than a (stock) GR Yaris. It's much more practical despite being heavier. It's significantly cheaper. This gen tunes really well, much better than others. .... I think they're probably a lot better than people expect.
    • WRXs are a pure pleb boring car these days. You need to get an STI to even get close to what a WRX used to be.
