hey all. just want any advice on what im about to do r32 gtst rb20 timing belt snaped and broke 2 pistons bent 19 valves and snapped 5 valves with guide damage aswell. everyone would say new engine but im not keen on that because the head just cost me 5g worth of porting and custom parts and had alot more work just done car hadent even done 100km before the brand new belt snapped which killed everything head is fixxable and i dont want to waste that money so now thinking bottom end rebuild and stroke to 2.4l which will bring my boost on early since i have a gt3540which on the dyno about half an hour before it snapped made 280rwkw on 18psi. i want to bring it on earltier then 5grand revs and boost it up to about 22 and hope make between 330 and 350 kw

the head work was port and polished with oversized valves custom springs and custom cams. the porting was huge about asbig as we could go safely.

and obviously new lifters stem seals and valve guides to suite.

Unfortunately you can now throw most of that out, if the cams and springs are any good, they will fit srtaight into a 25 head, just disable the vct. A top notch port job shount be more than 1k

at the moment im still waiting from a engineer report it was a defect in the belt from manu facture so they will only pay to have that engine fixed which i will pay the differance for the stroker put in. the head is already getting fixed just got to sort out the warranty for the block but they r goin to fight it and i dont know who to speak to about it.

    • 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.
    • You are all good then, I didn't realise the port was in a part you can (have!) remove. Just pull the broken part out, clean it and the threads should be fine. Yes, the whole point about remote mounting is it takes almost all of the vibration out via the flexible hose. You just need a convenient chassis point and a cable tie or 3.
