Injectors and Dyno Tuning

Ero_sennin · Post by **Ero_sennin** » Fri Sep 08, 2006 10:45 pm

I think one of my injectors has packed up.

Would it be fine to "refurbish/service" the injectors or buy new Injectors?

If servicing is a good option anybody know of a good place in PTA.

About dyno tuning, any recomendations for the pta area aswell?

Thanks People

Don't know about injectors. I got my car Dyno'd at SMART racing in pretoria. Those guys know what the doing. They also do injector conversions. Maybe you could ask them.

Was thinking of giving them a ring.
If you say they did a good job on your car then Ill most probably go there.

Wat did they charge you for the Dyno?

I donno what they charged gremlin but they quoted me R750, I normally go to Maus Performance in Rosslyn, they normally charge R450, about the injectors don't know but I can tell you one thing if you need to replace it through nissan you will need to dash out about R2000 per injector, you can get 450cc ones for R500 but then need to replace all 4

I think Iv already got 450cc.
but where would I buy those injectors you speak of?
Im not sure where to.

The only place I know of in Pretoria is Smart Racing, otherwise check in the speed and sound there is alot of shops in joburg, Smart Racing might be a bit expensive because they don't really have competition in pretoria

Geez injectors, that's where my nightmare started!

When you say one of yours has packed up, what do you mean? Mine worked fine but they were leaking fuel - no way to fix that. But you can get the filter basket replaced at Bosch Service Centre - you can also get your injectors tested there for spray pattern and capacity.

As for replacing, the standard ones are 370cc, and as mentioned above, are R2000 each from Nissan. I eventually had all mine replaced, but that also involves remapping the ECU to cope with them. Both routes are expensive, but at least with the second option, you can up the boost and get more power (if your exhaust gasket can handle it)

Aaah Leaky injectors the reason I cracked a piston.
Thats why I replaced the engine.
It seems One injector might not be working properly as the engine Idles unevenly if I pull each injecter seperatly One of them makes no difference in the idling.
Bugger more Money to spend on my car, and I havnt even started modifying

Bosch Service Centre wonder where they are?
Do I take the Injectors there or do I take the car there?

Thanks

Hmm, your test of unplugging injectors is not definitive - you might get the same results if you unplugged the spark plugs too. I would suggest then swapping the spark plug or coil with another cylinder and see if the problem moves with the coil or not. Also try that with the injector (which is obviously more of a pain to move).

Bosch - they're everywhere! Check http://www.fixmycar.co.za/regionselection.php. You can just take your injectors there - that's what I did. I used the Bosch in Midrand.
