What's the correct timing for the GT8 guys? Anybody sure?

My engine bay has a sticker that has some writing in Japanese and "10Degrees BTDC 650RPM" written next to it, yet from everything I've read including the ESM for the G35 - VQ35 Engines have 15Degrees BTDC@650RPM. Just doublechecking.

Cheers.

I can't help you at all.

But can you tell me what you think of your car? I've been seriously considering one lately. Since i've now gotten rid of the 34.

Whats insurance like? hows the CVT to live with? is it quick? considernig it's got an early model 350Z engine in it.

I'd go with what was written on the car before what i read some where else.

Yeah me too. The thing is, my engine scanner says currently running at 650rpm at 15Degrees even after resets, and I can't drop the ignition to 10Degrees at that revs. The car does seem to be a bit sluggish accelerating in the lower gears(maybe this is normal) but I thought a good place to start would be the timing.

What does everyone else have written on there engine bay and what car/transmission?

I cant find anything written in my engine bay but I do notice my car is a bit sluggish on acceleration especially from a rolling start and the transmission is in about 4th gear. I find that when I am in manual mode it hoots along when I am changing at 6-6,500 rpm. I think because the transmission is variable other than direct shift it tends to get in to 3 and 4th pretty quickly off the lights even when just putting along.

Just checked my coupe and it's the same 15degreesBTDC@650RPM

Cheers

    • Have a look at that (shitty) pic I posted. You can see AN -4 braided line coming to a -4 to 1/8 BSPT adapter, into a 1/8 BSPT T piece. The Haltech pressure sender is screwed into the long arm of the sender and factory sender (pre your pic) into the T side. You can also see the cable tie holding the whole contraption in place. Is it better than mounting the sender direct to your engine fitting......yes because it removes that vibration as the engine revs out 50 times every lap and that factory sender is pretty big. Is it necessary for you......well I've got no idea, I just don't like something important failing twice so over-engineer it to the moon!
    • Yup. You can get creative and make a sort of "bracket" with cable ties. Put 2 around the sender with a third passing underneath them strapped down against the sender. Then that third one is able to be passed through some hole at right angles to the orientation of the sender. Or some variation on the theme. Yes.... ummm, with caveats? I mean, the sender is BSP and you would likely have AN stuff on the hose, so yes, there would be the adapter you mention. But the block end will either be 1/8 NPT if that thread is still OK in there, or you can drill and tap it out to 1/4 BSP or NPT and use appropriate adapter there. As it stands, your mention of 1/8 BSPT male seems... wrong for the 1/8 NPT female it has to go into. The hose will be better, because even with the bush, the mass of the sender will be "hanging" off a hard threaded connection and will add some stress/strain to that. It might fail in the future. The hose eliminates almost all such risk - but adds in several more threaded connections to leak from! It really should be tapered, but it looks very long in that photo with no taper visible. If you have it in hand you should be able to see if it tapered or not. There technically is no possibility of a mechanical seal with a parallel male in a parallel female, so it is hard to believe that it is parallel male, but weirder things have happened. Maybe it's meant to seat on some surface when screwed in on the original installation? Anyway, at that thread size, parallel in parallel, with tape and goop, will seal just fine.
    • How do you propose I cable tie this: To something securely? Is it really just a case of finding a couple of holes and ziptying it there so it never goes flying or starts dangling around, more or less? Then run a 1/8 BSP Female to [hose adapter of choice?/AN?] and then the opposing fitting at the bush-into-oil-block end? being the hose-into-realistically likely a 1/8 BSPT male) Is this going to provide any real benefit over using a stainless/steel 1/4 to 1/8 BSPT reducing bush? I am making the assumption the OEM sender is BSPT not BSPP/BSP
    • I fashioned a ramp out of a couple of pieces of 140x35 lumber, to get the bumper up slightly, and then one of these is what I use
    • I wouldn't worry about dissimilar metal corrosion, should you just buy/make a steel replacement. There will be thread tape and sealant compound between the metals. The few little spots where they touch each other will be deep inside the joint, unable to get wet. And the alloy block is much much larger than a small steel fitting, so there is plenty of "sacrificial" capacity there. Any bush you put in there will be dissimilar anyway. Either steel or brass. Maybe stainless. All of them are different to the other parts in the chain. But what I said above still applies.
