Injectors stage2

[diamondsink]

Hi Jez

I have all the parts for stage two but no injectors, is it ok to use larger than 550cc nismo's?
Say 740cc?

Thanks

P.s are you able to check my timing when i come to get the chip fitted?

You must use Nismo 555s for the stage 2, 3 and 3a ECU upgrade. You can use whatever size you like if you're going for a custom map.

I've got 555s in stock - £359.99 usually, £319.99 if bought with an ECU upgrade :)

I can check the ign timing, no probs

Is S14a Stage 2 just Stage 1 with 555's, 17psi and your chip? If I installed a 360 degree thrust bearing in my T28 would it handle 17psi comfortably?

Are there both 555cc and 550cc Nismos?

You need an FMIC for stage 2 as well :)
The standard turbo is ok at 17psi, so one with a 360 deg bearing should be ok too.

Yeah, same thing really - so long as they're 555/550 and made by Nismo with the yellow top they should work with my ECU upgrades :)

Really? Excellent. I am currently debating having my T28 rebuilt due to turbo oil seals against buying a new turbo but the rebuilt T28 would comfortably support 17psi and spool a little faster with the 360 degree bearing?

[Jez]

It'd be slightly more laggy with the 360 deg bearing, but you prob wouldn't notice it to be honest.

Thankyou Jez, that's brilliant.
