Rb26 N/a Tuning

[Kaido_RR]

hey,

Was just surfing yahoo auction and found something very interesting

there not alot of info on it

"They are 6 connected throttles of RB26. The manifold for NA. It is the HKS delivery pipe attachment. Funnel kernel funnel 70 millimeter."

would be awsome setup if you had an N/A rb25 could grab that and then get a Adoptor plate

Cheers Michael

I'm not normally interested in N/A performance, but a N/A RB26 would be rather cool

Why the hell would you tho :s I wouldnt understand why you would bother.

n/a tune, i guess u never seen a 4age ae86

its like have 6 air filters

NA RB26 would sound rather tough....

However.....

PSI 4 LYFE!

so they are made from RB26 manifold or made for RB26?

[funkymonkey]

Its made using the individual throttles of an RB26DETT and some custom linkages, injector rails and trumpets.

If you guys watch the full video of where Tsuchia test drives the mines R34, a couple of cars before it is an R32 GTS sporting a N/A RB24DE with hex throttles. And it goes like a dog with deep heat on its balls. Also a few N/A guys in japan have used the L28 hex throttle assembly adapted to fit RB20DE's for some fun.

For a 120,000 yen that's actually fairly decent considering you get all the bits and pieces. An adaptor plate isn't hard to do either.

If I still had my GTS I'd be all over this one combined with a MAP sensor conversion / aftermarket ECU.

The first Skyline to start winning races was a straight 6 n/a called the GTB. In the early 90's autech made a tribute to this car by using an R32 GTS4 and putting an RB26DE n/a engine in it with GTR style individual throttles. Needless to say both are very highly sought after items

[BADR33]

thats pretty trick. if it was cheep enough i would use it on my rb30de but first of all i gota get it all together

i would see why they would do that. you dont need a turbo to have fun

[ignuz]

hmmm.. how much power do you recon you could get out of a R33 gts, s1 with that... and an aftermarket ecu, exhaust, extractors pod ( maybe even super charge it too ) Just, slightly interested..

i dont think you would superchage it as that would take away the point of having 6 throttle trumpets. and you dont put 1 pod on it. you have 6 little airfilters

it would be trick tho. i know they do it with v8s and those toyotas and they sound pretty mint so im sure a N/A skyline would sound crazy!!

[acsplit]

With trumpets would sound horn i just came back from japan and got to hear an r31 fitted with a genuine rb26de out of an autech 32 and i must say it sounded sweet

map sensor ecu and walah you have a very tuff sounding n/a car

If I get time I'll scan up the article on the Tomei built R33 RB25DE with the hex throttle treatment that beats GTR's and revs happily to 10,000 RPM. Although that engine had a lot of work put into strengthened internals too.

One of the reasons people do this is because of the different racing classes. For example in Australia, a R32 RB20DE GTS is eligible in the 2.0L production class racing. If you had a RB20DET GTSt it you get a 1.6x penalty, making your estimated capacity 3.2L and meaning you'll have to compete with V8's, GTR's and other larger capacity cars where you'll have no advantage. If you had a high revving RB20DE though, you'd be king of the 2.0L class (well close to... an S2000 would still kick your arse).

i drove an S2000 i wasnt very imprest with it..

How much power does an RB20DE make? The highest number I found was here, which quotes at 165ps.

Or I could get an SR20VE that puts out 190ps, and be a shorter lighter engine.

An S13 Silvia is over 100kg lighter than an R32 Skyline.

But yes, an S2000 or Lotus Elise / Exige would demolish either car and rule the roost, unless you're allowed to race Clubman style vehicles like PRBs or the Atom.

[funkymonkey]

the application was purely as an example. No one runs RB20DE's in improved production class, due to the power to weight disadvantages. There are a couple of N/A silvias being built up for it though.

[azn-det]

that would sound so nice

[Rolls]

If you mated it with an rb30 block it would make for an interesting engine

imagine the sound!! the butterflies!!!

how RB engines should be made!!!

and a stupid cam and crank so it can rev to 9k all day.

mmm if only I had money to waste.

I got an article on this in a R32 GTR book I got while in japan..

220ps/6800rpm

Automatic Gearbox

E-HNR32

Engine bay looks the same as a RB26DETT but on the turbo side..there ain't no turbo hehe just some big 'tuned length' extractors..
