I have a RB25DET 1.generation with the external ignition amplifier and stock coils. To get it to work with high boost I'm using NGK BCPR7ES plugs gapped to 0.60mm but it doesnt run very smooth with a cold engine or at low revs because of the heat value and low gapping.

I also bought a HKS DLI2 with twinspark\CDi but it came with a wiring harness for a rb25det 2.gen engine wich has different coils and the ign amp integrated in the ecu so I could not install it.

But I know I need a stronger spark! So what alternatives are there to improve spark on a 1.gen engine? I've heard the splitfire coilpacks are nothing else than stock coils with blue paint. And I think my stock coilpacks are in decent shape. Anybody got any tips on products?

You dont need stronger spark i reckon

You need GOOD coils, and GOOD plugs, and a GOOD tune.

Thats it. :D

The HKS spark box is only for when you get above 350rwkw, if your breaking down before that... coils is the likely option

I'm running a GT4088R with about 1.5 bars of boost now. It starts popping and misfiring under boost after that. But I want to run about 2.0 bar. And im aiming for about 650-700hp at the wheels

You have some sort of ingition issue then

Stock coils combines with the HKS box has many a time run over 500rwkw.

Plenty of Jap cars have done it :)

excactly, thats why I need a HKS box that fits my ignition system. the DLI2 amp unit apparantly doesnt. I cant find anybody who has made it work and how.

      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.
