Using a nissan GTIR intake on a 20V

[DR86FT]

will this fit on a 16v with the adapter plate?

[Vance]

it would fit as in the bolts would line up. fit in the engine bay is a different story

[DR86FT]

I think the quads r upside down with the adapter plate. So I don't think it will work. Maybe if the mounts are turned upside down on the gtir manifold

one of the current jap AE86 drifters uses one for his turbo 20v... i saw it recently in my travels, but is by no means a new idea.

OK we've established that all of you guys have seen/heard/used this before, but does anyone actually have anything to report as far as potential for performance, power characteristics, limiting factors or even a direct comparison to trumpets for example. I'd have thought just looking at it that it would be a bit too small, but might be an ok solution if you do something like what Frak described and increase the volume somehow, or you can use a big piece of pipe on the big inlet tube to increase volume of the system a bit.

So any cold hard facts? Dyno sheets, or anecdotal evidence of any sort?

[Sam-Q]

wtf, this is ae86dc we are on here!

jokes aside I am interested also but who would really test one airbox and then this one after a retune? Even if there are some limits due to volume and all perhaps it's not as relevant when it's this or no option at all.

I will bug this guy I know into making something happen about a batch. If it happens I will fit it to my car as a test run and see how it compares, I better keep my eyes peeled on a the a/r ratio whilst doing so though.

FraK: the way you did it sounds seriously awesome, must of taken a while yes?

[Vance]

no cold hard facts from me, but making an adaptor plate as uncle frak described you could make it hold as much volume as your hearts content by extending the side walls of the adaptor plate, aslong as it doesnt hit anything like the brake master.

How's the availability?

Hi guys, I'll get some pics asap, mine was for FI not NA, I wanted to increase the plenum chamber so I bought a 30mm plate of ally and dumbly decided to mill it out by hand(Sam....took effing ages! especially the inner curves to match the taper of the plenum cover.) I machined down about 24mm to increase the plenum volume. I do not use ram tubes inside of the plenum, I used a cutter in the mill that has a radius on it that was developed from years of development from one of the longest/most wins in IPRA in South Aust. I have been working with these guys for over 20 years, when they have made restrictors I have flowbenched etc to check air flow, they have come up with a radius that works really well so I used this to radius where the backing plate goes onto the quads(if that makes sense)

I also match ported the backing plate to the quads using a mill cutter so it's a perfect match, infact if you run your finger from the backing plate to the quades, you cant feel the step(this is without factory gasket)

The reasons I used the GTiR plenum were these;
asthetically it looks really nice being cast and not just some welded up box
I imagine Nissan put a bit of effort into the design with regards flow distribution considering the GTiR was their homologation rally car(Yeah I know it didn't do to well....hopefully wasn't plenum design problem :p )

I do have this old photo from the original engine mock up just to see how things would fit before I rebuilt the engine etc, in the pic the backing plate is semi finished, it ended up back in the mill to make it a little more asthetically pleasing.

[Sam-Q]

looks relly nice Frak, I admire your perfectionism.

So what did you install it in?

I see you welded up the big outlet off the side, any idea what that originally suited?
