I see what you are doing. once suggestion I would make with that auto though is a SERIOUS trans cooler for it. if that box is anything like a subaru box (both are jatco) then a rebuild on it is over $4k.

Currently, the engine guy doesn't think the auto will last behind it. The transmission is going to Paul from KEAS, who seems to really know his stuff. Yes I agree with the trans cooler.

The bill for the Hypertune one off plenum, fuel rail, (plannning ID2000 injectors), and 90mm throttle body, was solid, got to pay the bill for the street head port as well at the end of last months other bills....solid accounts. This months is bite the bullet with the oil pump. I'm initially trying Nismo, non N1 pump with hardened steel gears (not an N1). Using the N1 water pump. Gaskets are a mix of factory Nissan, but using the Tomei RB25 det head gasket.

The engine assembly continues. Hypertune plenum and 6 Boost manifold are pleasing products to look at. Hypertune plenum needs fettling for VVT.Got some compliments on the 6 boost twin scroll manifold, with twin scroll turbo combo.

this is a pretty sweet project man. :thumbsup:

What are the plans for it? daily, weekender or track warrior?

At the moment weekender. The build has taken long enough to forget why. I have a Magna and an Audi for daily duties. I had wanted to drag it, but feel less inclined.

more info on the Hypertune plenum pls :)

I guess I wanted one, they look bespoke. They are individual order for rb25det over rb26. I copped a serve from the manifold guy that it will spool later than a Plazmaman plenum. I haven't seen a comparo, There's a thread on Greddy vs Plasmaman. I just wanted one but the other factor was getting the throttle body, and fuel rail as one package. However it's coming off for adjustments so the VVT will work, something that concretely affects spool. The HKS Step 1 cams were chosen to retain VVT.

The transmission choice has been difficult. I wish there was something 3 speed and simple in all wheel drive like C4 ford. Instead the powerglide is available in awd, seen a one off TH400 on Calais turbo. As well Like most people I want some communication at decision time. The plan at the moment is re403a from the 300zx turbo, which has larger components than the re401a in the car, and mating that to the awd housing. The job's going to MV automatics, thanks to communication about the job etc. Other trans builders are yet to get back to me......

The panel beater is always big and critical part of a build. I've been satisfied with the one I've chosen. The pics show how far I've had the car stripped back, which is far enough to respray the engine bay to the matching final colour. And that it's a glass out windows out job.

The other aspect is the decision to "wide body" in many ways subtle is better and I'm and admirer of Chris Rogers restoration GTS4 for that reason. I have wanted to wide body my GTS4 for wide rubber clearance. I went with fibreglass rear quarters and GTR fenders, over going all GTR and stiching in GTR quarters. The plesant surprise is that for an old GTS4 there is very little significant corrosion as many of these were used in mud and snow parts of Japan, while mine has been looking soild structurally.

There are the "dark nights of the soul feelings" that having been stripped back so far, is it just a pile of rubble now or will it come together mostly to plan.

Having paid MV automatics, the trans 3k stall etc etc, was lost for a while and found again, causing just a small shortening of my life while MV automatics have tracked it down. Hope I see it in the flesh soon.

    • Yes. You will need to get the original boost sensor and wire it in. That is.... if you plan to use a stock ECU - even a Nistuned ECU. The Nissan ECU will not operate correctly without it connected. And yes, it will do annoying stuff like you are experiencing. You will almost certainly be better off with some aftermarket ECU, than trying to hunt down rare sensors.
    • Ok so ABS/TCS is "not" the problem. Yeah i know now about the ABS with Nistune(i told that to the Nistune guy) but iam not 100% why or why i dont have ABS. ABS cube is in the engine (always has been) but i had braked couple of times rly hard and brakes just locked and scream. Does all Skylines have ABS cube? That boost sensor https://www.sau.com.au/forums/topic/367633-wtb-r34-gtt-turbo-pressure-sensor-pics-inside/ Is this it? I need to ask but i have a picture of engine bay and i do not see that (100% is not in that place) If i do not have this the car can do what mine is?(cutting around 4000 rpm) Here is the pic of my engine bay(only one i have) BUT i think i dont have that cuz loom was used from my RB20DE NEO and i know (obviously) that it does not have boost control or any wire to that...) so maybe that is the problem? (i dont know for 100% if that car where the engine is from had that)...but i dont have the loom from that
    • I'm with you here. It's either loom has an issue, OR, injectors are not functioning properly. It could even be they're just constantly dribbling, hence the wet, but not firing.
    • Depending on how long the car sat it is very possible for injectors to be stuck open or closed, I'd get them cleaned and flow tested. Other than that, obviously when the loom changes and the car doesn't start any more....the loom is suspect so some tracing / comparing may be required
    • Harness is for a s1 Rb25det, and it is engine and lower harness.  the old harness had broken off plugs and was in very rough condition/exposed wires and splices etc. it is not able to be put back on the car, I could visually inspect to see if they had rewired any pins on the ecu plug. The fuel pump definitly isn’t turning off it’s an external pump and very loud you can hear it. Will look at the other harness tonight, am also going to pull the fuel rail and watch the injectors spray, will update here with what I find. Pretty sure at this point it has to be something to do with injectors because car will fire up on starting fluid and cas is clicking the Injectors. Fuel pressure is steady 43psi
