I've heard the suzuki bike ITBs can be retrofitted, but it's a rumor. What compression you gonna be running with em?

[Full-Lock]

ive seen those motorcycle ITBs on KA's and shit..believe they were suzuki

[Unholy S14]

gxr's baby!!!!!!!!

[DOOK]

yeah, gixxer 1000s to be exact is what most use

[GSXRJJordan]

Ewwww N/A SR20. Reeks of a Sentra.

Yeah GSXR1000 throttle bodies are easy to use (the throttle cable even pops right in).

Basically you need a spare intake mani, and just like the KA swap you keep the part of the mani that bolts to the block, but cut before it turns down - about 4inches worth. Then use some rubber hoses and clamps (or be a man and Tig that bish) to get the ITBs onto the manifold.

The tough part is building a plenum - you want it to be volumetrically sound (meaning all the TBs get around the same amount of air), and it's tougher than it looks. You can 'sync' the throttle bodies if you get close, but to do it right means you'd need A/F's or ex temps on each individual exhaust runner... not fun.

Anyhow, the easiest thing to do is cut/flip a GTIR manifold.

[Unholy S14]

hahahah sentra.

thanks for the info, repped.

Won't RB26 throttles work on the 25 head? They seem to go for not too much money.

[smelly240]

ikeya formula has had one for years - and the throttles im using for his are off a 750 - but now looking at the sunny throttles i might do something similar to the DSG setup above... that plenum is way nuts.

i think the mailbox pipe is gonna get scrapped.
