omg after alot of mucking around i got my car running smooth, still yet to take it to a tunner, not sure why but it is running really smooth with 55 odd psi fuel pressure, maybe something to do with the chiped ECU that came with the motor,

anyway hit roughly 60km/h boost hit and was going sideways :cheers: to a small degree but enough to make a grin on my dial, BTW this is my First RB & to second that vl & to spesify rb25det in a vl :P

yah i know its not ecu controlled, when i ran it at 38 it splutters and stuff, all in all its not tuned, and right now its the stock VL turbo fuel pump, i have an 044 sitting ready to go in. does any of this make sense for the 55psi fuel pressure?

Sounds like a stuffed pump if your having to up pressure to get any flow from it.

I wouldnt risk it that way either as its on its last legs... i wouldnt even drive it till you get a decent pump in there

yeh 55 is way to high lol. i have to buy a adaptor to get rid of my standard reg to instal my adjustable fuel reg, and il be setting it to about 38-40. just so i can drive to tuners...

    • Well, my new WMI system took much longer to finalize. I actually missed my dyno appointment last Friday and lost my 150$ deposit. I'll be going back in the next week or two.  To sum it up. I only kept the AEM tank from my old setup. I replaced the AEM pump with a higher flow/pressure ProMeth 30GPH pump. I also swapped over to a 6AN low pressure feed line to the pump from the tank. There's also a pressure switch you cannot see on the pump high pressure line.    This is feeding 6x 200CC direct port nozzles and 1x 500CC Pre Throttle body nozzle. All fittings are Swagelok, because well why not. I also have a 300PSI pressure sensor up front.    I now have my Haltech ECU controlling everything. I start my pump with a basic relay at 5PSI and deadhead it. I then PWM a 3000CC methanol Injector to control flow starting around 10psi. The pressure switch in the trunk, along with my tank level are safeties before I ever get to 10PSI, and then I use my pressure sensor upfront as a secondary safety to cut the WMI and corrections in case the injector blocks or a line ruptures.  Wish me luck on the dyno!    
    • So, I'm back with bad news. There's no jack long enough on this planet that will reach the front subframe. If by some chance there is, it would weigh 200lb's.  I purchased a long reach jack... The damn thing weighted 120lb's and was massive. Didn't even come close, was still short at least a foot. It was a pain, but I brought it back. Next I decided HA! No problem, I'll get an Extra long reach jack. Well, I couldn't lift the box... It must have weighed 160LB's and luckily there was an open box in store. I took measurement and was still nowhere close.  Sadly I've lost hope and have accepted defeat. 
    • Thanks for that tip, niZmO_Man. I think the battery is OK. It's quite a new one, but I'll check. Last time I needed a new battery, everything electronic was fine, except that there wasn't enough current to turn over the starter. I decided to order one of the partial AV system translation CDs from Car Audio Workshop in NZ. That might have some effect, or help me diagnose the date problem. 🤞
    • I suppose it was relatively stock too, the JZ motor handle most mods thrown at them without even breaking a sweat 
    • I saw your intro update, are you sure you've actually had a starter motor failure? You mention it could be the alarm causing it. I'm assuming you've got a no start issue, but what are the exact symptoms, as there could be a few reasons it has stopped wanting to start.
