Hi Just trying to determine if my sensor is gone or something else is playing up.

ive noticed my water temp on the guage is very very low and seems to even go down after a 30min drive on fwy it went to a quater.

I warmed the car up for 15mins this morning with the heater on full and looked at powerfc and its sitting at 55degrees and no movement on the guage.

thermostat?sensor?bleed the system?

thoughts?

thermostat, replace it

use a tridon one, they're fine. Just make sure the little bleed point is at the top or you'll have issues (as they're not marked like the Nissan ones)

don't use a low temp NISMO thermostat, pointless

Even further to this, last weekend whilst tuning my boost controller (so the engine should have been toasty warm) I coasted down a hill and the temperature gauge fell quite low. This finally convinced me that my thermostat (in my new Neo) was not right. Had been taking a long time to warm up in the cold weather we've had lately, and when looking at the actual coolant temp in Nistune it was lower than it should have been. And the last tank of juice went about 20% faster than the recent average.

Thermostat swapped out today. The one that was in there had damage most of the way around the edge. Not possible to tell if it warms up faster until tomorrow when it is fully cold again, but on the shakedown drive I noticed that the oil temp was back up to numbers that I haven;t seen since much hotter weather, so it would seem that it was the root cause of cold running.

      I need more than help to finish my R33

      Don't use that manifold. Please don't use that manifold. Sunk cost fallacy is not worth the later pain. None of these will be relevant to the change that will come from the different turbo and manifold. As in, the effect of the exhaust will be nil, regardless of what else is changed. And all the cam and fuel system stuff is not changing either way, so has no effect. The turbo and manifold (and to a small extent the wastegate)....big change.

      Just wanted to say thank you for your input   my man (lead mechanic by trade) and I have done a heap of work as you can imagine just to make the hot side work with the dump pipe, stupid massive intake on turbo, trying to get the waste gate on was not fun.  I’m kinda getting to the point where I don’t know if I try and make this work and not throw all this cash and time away or do I scrap the lot and start again? the Apexi I’ve got was tuned for a few slight differences:   Tomei pon cams (mine are stock neo) Turbo smart 38mm external waste gate (mines 45mm replumbed) with stainless screamer pipe  3inch turbo back exhaust with high flow cat Sard 800cc top feed injectors Sard adjustable fuel pressure reg

      Out here E90s are the cheapest way into a sporty-ish car because everyone knows just how expensive the repairs can get. 8-10k USD for an automatic 335i.

      Noted. Have noticed BMW are more 'high maintenance' for sure. They've attracted my attention as I think the used car prices seem reasonable vs other options, and the extra quality overall vs a commodore / camry / corolla or similar of the same vintage is appealing, especially the interior, and they are more on the sporty side whereas the others mentioned can be more cruising or economical A-to-B only.

      Haha yeah I know, this is SAU after all, why are we talking about BMW's of all things!? I hear you on the 'don't have to worry about it' side of things. Having been fortunate enough to be have been able to buy a brand new motorbike or two...never really enjoyed them as much as I'd have liked as you worry so much about where you park it, will it get scratched, stolen, attempted theft, knocked over, etc...and yes dirty. Older less valuable bikes you can just go where you want and park it wherever and not really worry that much in comparison. And who cares if it gets dirty! Never owned a V8, and have had my eyes on VE / VF commodores for years but with their prices climbing so high, the M3 has come into focus more as prices are much closer than I've ever seen...is it a potential contender now?...of course need to factor in the S65 'maintenance' especially and like you said general M car 'tax'. One can dream anyway. But more on the reality front - did read the whole 330i thread as well and was a great read too, both threads enlightening as I've never even driven one of these cars! I do recall 330i didn't seem to have the same amount of issues for almost the same car (turbos and related differences notwithstanding)...perhaps down to getting it earlier in it's life so looked after better than the 335i? Perhaps so as your 130i has been good and quite similar, so finding a car that's been looked after well is the especially-crucial-BMW-first-step.
