[Anyone Using Hks Twin Power Cdi?]

Get yourself a good 30A plus fused automotive relay and cut the +12V supply to the coils and connect it to a relay on pin 87. Run a high current wire from your alternator terminal and connect it to pin 30 on the relay. Ground pin 86, and connect pin 85 to where the coils used to get their +12V from (the loom). This allows much more current flow at the coil as there is less voltage drop across the length of the wiring in the loom.

Thanks for that very good instruction :-)! I will modify this weekend!

But one Question I have: I run the R33 series 1 GTST with the amplifier (not supplied from HKS twin power ignition systems). Have I to set the relay after or before that amplifier. I think before - right?

Thanks and best regards from Germany

The most important thing you can do though is to insure you have an excellant power supply to your coils and I don't mean pull out a voltmeter and and proble it to check for 12V either. You need a good scope to probe the power supply during coil firing. If you see more than a 0.5V drop when the coil fires you have a big problem. My Car had 2V drop !!!!!!!!! Old wiring/relays etc ass up to resistance that costs in voltage. I wired up a new relay in the fuse box to run my coil power feed directly and I now have a 0.2V drop when the coil fires. Makes a huge difference.

Hope this helps...

Hello Mike,

what did you excatly, to modify the relays and wire. I would like to do the same, but not sure how.

Thanks and best regards

Hello guys,

have these PONCAMS

http://www.nengun.com/tomei/pon-camshafts

Part Number: 143020 "ECR33 Series 1 (RB25DET) - Duration: IN,EX 256 Lift: IN,EX 8.5mm Skyline - R33 GTS-t S1 - ECR33"

and need the technical specifications to adjust them. Only found the duration, but not the opening and closing times as for example you can see here:

May anybody help me? I searched in the web, but without any results.

Thanks and best regards

[Rb25det Running Very Rich Under Full Boost]

Hello,

my problem is solved. It was the BOV. It was completely screwed in. Now it is more open and the car is running normal.

[Rb25det Running Very Rich Under Full Boost]

Hello from Germany,

I have the same problem since some days. My car was mapped 2 months ago and was running fine. Now it is going rich when boost comes up. The wideband-AFR (AEM) shows the ratio about 10 and there is no power any more. From the beginning to the (under) half throttle position the AFR is normal.

I have the idea, that the intake pipes are leaky, maybe where the bov is fixed on (GREDDY Type S) - but have to check. Will check the fuel pressure regulator too..

cheers

[Fuel Pump Direct Feed Rewire.]

pidibump!!

I read the whole 12 page thread. Most people talk about r33 or 32 gts or 32 with Aftermarket pump.

What about Stock fuel pump on a GTR 32 with something like 350whp.

Any benefit?

Maybe, that this help you out:
