hey guys, i have an r32 rb20det, all standard apart from exhaust and fmic, i have recently gained a miss. it is running standard boost and when boost kicks in it starts to miss and backfire a little.

i thought it was the plugs so i replaced them with some new ngk bcpr6es and most of the miss went away but it was still missing a little and after about 100km's of driving its back to the way it was.

could it be the coils, timing or dirty injectors?

any help would be much appreciated!

thanks,

Tim

Coils or coil harness for $500 thanks.

Also not sure if the BCPR's are helping or not.. the R's are the resistor type plugs, I run BCP6ES (non-resistor type).

It'll be your coil packs more then likely. I had a similar issue on my hr31 (rb20). I would check you plug gap first though, it makes a big difference if you have to big a plug gap.

I bought some new plugs that were a 0.8mm gap and I also used high temp silocone around the coilpacks to seal any cracks and the problem went completely.

    • I don't know it is due to that. It could just be due to load on track being more than a dyno. But it would be nice to rule it out. We're talking a fraction of a second of pulling ~1 degree of timing. So it's not a lot, but I'd rather it be 0... Thicker oil isn't really a "bandaid" if it's oil that is going to run at 125C, is it? It will be thicker at 100 and thus at 125, where the 40 weight may not be as thick as one may like for that use. I already have a big pump that has been ported. They (They in this instance being the guy that built my heads) port them so they flow more at lower RPM but have a bypass spring that I believe is ~70psi. I have seen 70psi of oil pressure up top in the past, before I knew I had this leak. I have a 25 row oil cooler that takes up all the space in the driver side guard. It is interesting that GM themselves recommend 0-30 oil for their Vette applications. Unless you take it to the track where the official word is to put 20-50w oil in there, then take that back out after your track day is done and return to 0-30.
    • Nice, looks great. Nice work getting the factory parts also. Never know when you'll need them.
    • Thanks @jtha7 I will have a look around tomorrow but it is a prick of a spot. These are some photos i tried taking 
    • I take it that the knock retard is from bearings tapping a little tune? Thicker oil is a fragile bandaid. You need a much bigger oil cooler and probably the bigger pump being discussed.
    • Hi @Chupapy i had several leaks from coolant pipes being corroded, i also had one leak on back of the head onto transmission. For me that leak was from the turbo water line. Follow the line to the back of the head The hose and metal pipe had perished these are the best pics I took of it at the time
