just after some part numbers for spark plugs that people are using in R32 GTR's.

mines basically stock. put the listed plugs in there and its miss firing around 6000rpm.

PFR6A-11.

BCPR7A were in it and went alright but i would prefer some platinums or iridiums.

anyone run PFR7A-11???? the higher heat range should fix it but would like confirmation from someone using them before i spend another $90 on platinum plugs...

Mate Go Copper plugs much better spark then iridiums

NGK BCPR7ES

at around ~3.50 a plug i went from iridiums in the six range to these (little bit colder) in both my 300rwhp+ RB25 r32 and 307awkw r32 gtr and instantly better spark/idle/lack of misfire etc...

Pregapped to 0.8mm so if you intend to run a little extra boost would be perfect

amd at $21 to chang you can 5sets of new ones before getting near what iridiums cost...

Ps every tuner inc the tuners that try to flog you with HKS/GREDDY/TRUST plugs will recommend these if they didnt care about the markup on the other iridiums

ask around plenty of peeps on this forum using BCPR7ES as they are the go!!!

Actually i had these PFR6A-11 in my rb25det r32 first dyno 220rwhp heaps of missfire

only thing i changed was plugs to above mentioned Instantly no missfire then a bit of Afr fine tuning and managed 322rwhp with everything else the same!!!!

i run PFR8B-9 only cause i'm lazy and don't want to change plugs as often but cooper plugs have less resistence and therefor give slieghtly bigger spark, the smaller the gap the less chance of the spark getting blowen out and more low end torqe as the bigger gap gives top end .8 or .9 is ideal for allround.

hey kraysie32 thanks for part no i have been trying to find what cooper plugs the 26 runs i have a race coming up with a mate in a vz 5.7 that just had engine rebuilt after i beat him with his 11.6 and am going to need every advantage i can get.

      V37 Radiator removal

      By Duncan · Posted

      So, this shouldn't be such a mission, but there were a few tricks so I thought I'd post up a DIY for it. This was on a Q50 Red Sport but I doubt any other V37 model is very different (maybe just less steps for the intake heat exchanger hoses) I pulled the radiator out to flush it because the car was running hot at the track, but obviously the same steps apply for changing a radiator for any reason including an upgrade. If you are removing the radiator, you of course need to drain and refill, so have 5+ litres of blue coolant ready. You don't need to drain the intake heat exchanger to remove the radiator but depending on your plans you may need a couple of litres for that as well. You will also need something to deal with the auto transmission lines, I used 2x 8mm rubber caps on the radiator side, and a short length of 8mm pipe on the car side.....unless you can block these lines quickly you will loose AT fluid and it may be enough to hurt the transmission if you don't refill it. Other than that....lets go... "First, jack up your car". Yes really, and put it safely on stands. If you are not confident doing that you need to give this job to a mechanic

      If the forester is anything like our old 2007 GTB Liberty, I could near on run ling Long's and "rate them", as no matter what, it just hung to the road, even when abusing it in a hard launch in the wet, or throwing it at corners.

      Boost cut after swap(RB25DET NEO) R34

      By GTSBoy · Posted

      Don't even try to run it on the stock ECU if you're going to have the boost controller bring boost above ~10 psi. I've already told you that. If you use the Nistune ECU, you will need to CAREFULLY read the available documentation for Neo tuning, and read some threads on the Nistune forums, to discover the various things you have to do to prevent the ECU from going bananas when the boost is too high. The is a table associated with th boost sensor that must be modified to prevent it from shitting the bed. This is just one of the things that you will need to do to the tune in Nistune, because the Neo turbo ECU will be expecting to see a number of things (such as the TCS) that are not there, and you have to block the DTCs on those. It is totally not surprising to me that you are having the problems that you are, but the solutions to these problems have been known for >15 years. So just get it done.
