GTiR Quad Throttle Bodies

[Onizuka]

Hey guys, im buying a GTiR quad throttle body manifold tommorow and i was wondering if anybody has any pictures or info on this conversion. I saw pictures about a year ago and i havent been able to find them again.

thanks-matt

kewl, i just found this, its a rwd sr20 with the GTiR head and quad TB's

this is going to be an interesting project. I cant wait to see it.

Not easy to do but it can be done...

First the plenum points the wrong way (i.e. towards the firewall), so you have to somehow make it point the other way.(cut and reweld i think)Then the ports are different shapes so the head and throttle body flange need to be modified.Once you've got it bolted up you're going to have to re-run loads of vacuum hoses and make a custom linkage for the throttle cable...

Look up arkman0 on Freshalloy...he did it a while ago.

B.L pretty much summed it up though. You'll have to port match the head as well.

Here's a good Nico thread discussing...http://www.nissaninfiniticlub....ottle

Yeah I know about the flanges and the plenum opening on the wrong side. Im willing to spend plenty to get this to work because I got the manifold, throttle bodies, 440cc top feed injectors and top feed fuel rail for $228 shipped. Thats $1000 cheaper than aftermarket ITB's with all the hardware and accesories nessesary to make it work. $2-300 worth of materials, machining and welding should be plenty to make it work.

Apparently I also need a resistor for the GTiR injectors because they are a different impedence (im almost positive they are low impedence as opposed to the sr's high impedence injectors). Anybody want to buy the Sard side-feed 550cc injectors i bought like a week ago? :pface

I was thinking of using the GtiR throttle bodies too. Check this guys site out, it look like a pretty bad @$$ setup

hey turbosaregood, thanks for the link, and welcome to the site!

That guy has some badarse cars. Too bad he doesnt have any info on how he delt with the fuel rail.

GTiR's are low impedance (2 ohm I think) and SR's are high impedance (11 ohm).

Thanks!

I saw a GTiR swapped sentra just today at a shop in harrisburg... dude i think you are in for a hell of a project.. but that car was awesome.. and man did it rumble.

[Onizuka]

Im ready and willing though, it should be fun

Hey Matt,

arkman0 is a local guy here that goes to UCF with me (he's a mechanical engineer too :pface) If you need any help with this project, I can put you in touch with him. His name is Noah, and he's a real cool guy:)

He and Estevan do the harnesses and swap services for Enjuku...

but...

Noah did it, the results were less than great. It took a lot of work (as described in FA) and at the end of the day he ended up switching back to the stock settup. Maybe if you had some sort of management system like a Haltech or even a Power FC you could make enough changes to have it work right.

I think the theory is good but in application it just isn't pretty.

I got such a good deal on the parts its worth a shot for me. Plus im interested in learning how to do stuff like this. I might take you up on that offer later when i get a chance to actually work on this
