Yo this is the ***** for us sr20 Riders
no sure of the cost of it but i beat its worth it!!!

NIIIIICE!!!! :D Looking at the Yen symbol... I'm guessing its about $1980.


Ben

about how much hp could you gain from this!!!!http://216.40.201.38/contrib/sz/killtheimu.gif
:D :D

Got an e-mail back on the blue color designed ones and the bloke said $1,200. He said it would be available soon (this was about 6 months ago) so i should check with him again.

Cossie

Actually it would be about $1400. That would be a nice upgrade, considering they have the 46mm Throttle body like the Gti-r and go up to 50mm.

Yo I want this upgrade!!!

Tell us exactly why you want this upgrade. You better be packing some serious mods before plunking down $1400 on quad throttle bodies.

Why not get a RNN SR20DET quad throttle body intake manifold? The only thing is, you gotta have a machine shop drill holes so it can bolt up to the head. And also, the ports are slightly larger, so you would have to port match it or go full out with a port and polish but im sure you would have to do that with the aftermarket kit also. With the aftermarket quad throttle bodys, you would need a stand alone engine management because you can no longer use a MAF. The GTI-R quad throttle bodys allow you to use your stock MAF and ECU(although it wont run up to par), however, the price diffference will allow for a reprogrammed ECU or possibly a stand alone. The manifold will run with the stock ECU, but because of the nature of quad throttle bodys, it goes from vacuum at idle to full flow at WOT almost instantaniously making it VERY hard to tune, so it wont run optimally with the stock ECU. BTW u need top feed injectors. 90 240SX KA24E injectors fit and have the same 260cc flow rating.

What "blue color" ones are you referring to???
The ones from EFI in Australia?
If so the price quoted is obviously Australian dollars which is WAYYY less than US$1200. Close to US$750 now...

If those are the ones you are thinking about, they said that they will be ready end of fall.

If Im not mistaken, I read on G20.net a post from Darth Roffe stating that there are minimal if NO gains to be had with individual throttle bodies on SR20's.

My guess is like others mentionned, unless you have SERIOUS mods, this wont be very benificial.

Who is this Darth Roffe guy? I really find it hard to believe that there are no gains to be had with ITB's on an SR20, why would Jun's N2 Race spec engine have ITB's? Its an SR20 with high compression and cams... I cant see why a high power all motor car wont benifit from ITB

Like said, if there are serious mods.

Darth Roffe is George Roffe :)
SCC article on DET swap ... remember ?

Who is this Darth Roffe guy and what makes him the last word on ITB's?

Is he that guy on the SE-R list that never has anything good to say about anything new unless its from JWT? That guy's funny. Always talking smack and causing ruckus.

Did this guy install ITB's onto a modded SR20 and strap it onto a dyno? Where are the numbers showing minimal/no gains? Was the motor tuned to take full advantage of the ITB's? Or was it just slapped on and dynoed?

Id not say his word is definitive.

But Id beleive his claims (George Roffe) as much as those from Mike Kojima, Rob Cadle and a host of others, before I beleive any speculations.

Though I agree it would be nice to have dyno tests with ITB's.


***********EDIT**************

Ok lets stop it right here, before Geo starts smacking me around for miss quoting him, this is his original quote (I did some deep digging.). Apparently my memory is swiss cheese.

"A larger TB on an SR20 will give you no additional hp. It will improve throttle response some, but that's it."

Geo


MY BAD
His quote does not talk about ITB, but larger ones.

They're cool looking - but without a head worked to flow the additional volume and cams to match (probably pretty aggressive profiles- i.e. not street friendly), there may not be any gain at all.

Ok well I don't know the man first hand but. My first impressions of him was that he's an a$$hole. But after sitting back for almost a year and reading his posts to the list I've come to the conclusion that yes sometimes he's a bit harsh. BUT the man carries a lot of USEFUL knowlege. He's one of the more Sr. members in the SR20 community. And with time comes knowledge.

Granted I'd love to see a test sheet on these, but anyone that's willing to throw away $1300, on a hunch really should be addressing other issues.

True. A$$hole or not, I'm sure he's a smart guy.

True again, but I think people should keep more of an open mind. I'm not skeptical on ITB's and I'm also not a believer in it...but I am curious and I hope they turn out to be a worthy investment for me in the future.

Because it would look good in a signature block. :rolleyes:

We have a winner.

-GP-

Rob Cadle made a long post to the SE-R List a while back about this, and it goes into the physics of individual throttle bodies. If my layman's memory serves me well at all, he talked about faster cylinder filling improving throttle response. It was in the last couple of years if you're in a searching mood.

The Pulsar GTi-R was a turbo production homologation for rallying. Draw your own conclusions on why it had quad TBs.

None of you absolutely need this on your SE-R, so don't worry about it.
