Hey guys, I've just discovered that the St Marys United up the road from me has Boost 98 (didn't see it last time I was there... must have missed it), however I'm wondering about the effects of E10 on an "old" car? My car is pretty much dead stock however I will be running 10 psi soon. It'll be fine for that without anything done to the ECU, etc.?

I've done some searching in these forums and it seems that generally E10 is safe to use in the Skylines, but has anyone been running it for a few years? All good? Fuel consumption?

Also, would I be OK in running this using a PowerFC on a Supra running 18 psi boost? I know this is an SAU forum :D I'm asking more as a general PFC/high boost question - any problems with knock increase? Or should I just stick with a non-Ethanol fuel?

the shell v-power racing that used to be around was an ethanol blend, and i'm pretty sure the new bp ultimate is also an ethanol blend and people ran these without any issues. most people only seem to have issues on older cars and they find it starts making them run crap after a while. i put this down to the fact that ethanol blends have a cleaning effect and in a car with a lot of crap in the fuel tank, lines and filter can end up with this being broken down and ending up in the injectors. my advice would be that if you do plan on using it and haven't changed your fuel filter for a little while, do that first. then in 6 months time change it again.

i've been running e10 in my SSS pulsar (and other cars i have owned in that time too) for quite a few years now and have never had an issue.

I tried the United 100 octane and wasnt impressed. The car was tuned on Ultimate so I guess it has better knock protection.

Now Im running Southland e85, I got sick of having to adjust the timing for every different tank of 98.

I dont see the point of using E10 unless you have it tuned to suit. I tried it on my turbo commodore without a tune and i got considerably worse fuel consumption with no gain in power. You really need to advance the timing to make use of the ethanol in the fuel.

Ah, I was simply asking because the price of their 95 octane E10 was something like 15c/L cheaper than non-ethanol blend 95 octane fuel!

However, after speaking to a mechanic, I've decided to steer clear because there have been reports of it eating rubber seals and things. Probably not worth the risk for a few dollars...

      Mistakes were made, my R34 Story

      I'm actually not sure - I think it was "Stealth Performance" (It really is near impossible to find a FEMALE 1/8BSPT to 1/8NPT male at ALL) but having the thing leveraged on a 90 degree angle on a small aluminium fitting is not too smart. Also in not too smart, I've drilled out the center of the broken fitting so there's maybe 0.00001mm of thread to bite into, so yeah. I may have to get it drilled/tapped/plugged entirely. Given I could conceivably tap a thread/adapter/pressure line in any point in the oil system I suppose it's feasible to run a line to the Nissan Sensor to keep the dash working. Do these exist in AN fittings and the like? Like an AN fitting that has a NPT (or other?) thread as well for putting a sensor in?

      Anyone running the VQ37VHR with forced induction?

      I would agree.  There will be an amount of boost you could run safely with an otherwise factory system, but it would be low enough to not be worth the cost.  And if you are reliving your 20s, you know a 'little bit' was never enough. Personally, if I didn't want to spend the money, then stick with NA bolt-ons, and maybe a tune.

      Fuark, at least the motor survived. What brand was the fitting that snapped?

      Wrong question. There's no point in spending the rather large sum of cash and effort to add turbo, without taking it to the "sensible" limit of the motor itself. If you have to upgrade injectors, etc, then so be it. That is a tiny fraction of what it will cost you to turbo it.

      Measure voltage at the starter solenoid terminal when the key is at start and it has clicked. If it is really low, then the suspicion falls on the ignition switch (contacts or wiring thereof) as causing a voltage drop instead of sending enough volts to throw the solenoid all the way to engage the starter itself. If it is a decent voltage, then the suspicion is on the solenoid. Might have s horted coil, or might hva dirty contacts. Rip the starter off, dismantle, clean up contacts and inspect winding. It might not be possible to see if there is a short in the winding though. I have a spare starter here that I could measure the resistance of the coil, as a guide to about what it should be, if you need a comparison. <parts hoarder>No you cannot have it.</parts hoarder>
