Injector Advice (again!) - GSXR throttle bodies
Badger_McLetcher - 23/3/15 at 08:04 PM

'Evening all, following on from my previous topics I've got some GSXR throttle bodies to suit my AJ30 engine, was wondering if someone could recommend some injectors (roughly 300-330cc/min) to suit? I know the S2000 ones are about 370cc/min and fit directly, however they are rather rare and expensive from the looks of things, same with Blackbird injectors. I've looked at other Honda injectors and can't seem to find anything of the right size and form.

I was thinking of either some Bini Cooper S injectors (330cc/min) or some SkylineStagea units (370cc/min) and modifying the throttle bodies to suit (drill and ream to size).

I'm just wondering if someone has some first hand advice on this subject, I'm leaning towards the Skyline route at the moment - at least I get 6 injectors!

Cheers

6 injectors around 330cc.....is this engine going to have monster power?.

Only about 240-260 initially I'd have thought, I'd just like to leave a bit of development room

Edit: I should point out I'm looking at the 330 and 370 injectors as I can't find anything closer to 300 at the moment, though the search continues.

Vauxhall Z20LET standard injectors are ~330cc/min, and high impedance.
Focus st / volvo t4/5/6 injectors are similar capacity.
Vectra vxr might be suitable, and would be a set of 6.

I have a set of blackbird injectors (unfortunately only 4 though) that have been cleaned and serviced and come with new o-rings etc. I was going to put them on ebay but if you are interested make me an offer?

Hi Pete, thanks for the offer but I'm currently leaning towards converting the throttle bodies to accept normal Bosch style injectors (like the Z20LET items, cheers Dave) as that gives me a bit more future proofing in case of injector failure or upgrade!
