let me get in on that b cam action!!!

I'll be looking fairly seriously at some vct development for my GTR. I'm not going to shell out for hks v-cam that's for shure!! It would be interesting to get intake AND exhaust happening.

How hard could it be?? ha ha ha

Time for some more big pics.

I've started work on the sump today.

How it started

After some drilling and cutting I got the plate out. They weren't designed to come out easily

Starting to design the new guts of the sump.

Since we've put the engine back in Damo's car, we have found the reason we lost so much power in Targa. The lifters for cylinder 2 are rooted

More pics of the sump

Completed cardboard mockup

I made a mount (high tech treated pine), so I could mount the oil pickup asif the pan was connected to the block. It's no wonder they run bearings. The pickup will be moved to the middle of the pan.

I got it all cut out in steel. only have cut 1 trap door hole so far, need to to cut the others out, weld the hinges on, then put it all together

Sump is getting close now. Only need some small angle steel to attach the cover.

Gates and baffle insert.

Dummy fitting the insert.

Insert welded in, and pickup modifications complete.

Cover modifed for the new pickup. got to take a plasma cutter for a spin....they are awsome

design is good but I'm not sure about the 4 tabs that secure the centre 'box'. they are effectively stopping oil flow around the box. they will kind of act to reduce surge a bit but will also reduce flow in and out of the box. just something to think about. you could always hole saw them so oil can flow through or just cut them down a bit smaller (but could be tough now that it's welded in).

otherwise it looks sound.

FWIW, I looked at fitting the RB26 windage trays to my RB20 as I thought the racier RB26 would have a design better than the lowly 20. I was wrong. RB20 windage tray is better.

So I wasted an hour of my mate's time milling my RB20 girder to accept the 26 trays.... because of course, I assumed it would be an improvement without actually checking huh.

What a Doofus.

yeah 26 one is pretty crap and a fairly compromised set-up all round (they do have a better pick-up though). their only good point is they can look kind of cool being alloy instead of the cake tin GTST gear, not good for their weight though.

The idea is that the oil will hit the baffle, and be forced into the gate. The baffles arn't sealed, and the oil can go under and around

I'm referring to the windage trays you noob, not the sumps. :miner:

i know you monkey. hence why i said:

    • 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 
    • Check the injectors flow evenly, and are actually flowing what you and the ECU think they should be flowing. If it's starting up on starter fluid, you have a fuel issue. Is it possible under cranking your fuel pump is turning off?   The harness you replaced, is that the whole engine harness? Do yourself a test, and drop the old harness on and plug it into the Z32 ECU. It's possible they've wired things different. From memory S1 to S2 is different in RB25 and you may have a wrong loom
    • I haven’t pulled the injectors to watch them spray yet but they are clicking from the cas and all of the spark plugs are wet with fuel. I’ve thought the cylinders were being flooded from the beginning and was hoping fuel pressure would fix it. Tonight I am going to pull the rail and watch the injectors spray. Don’t know how to test/diagnose if the plugs are firing in correct sequence but that should be a timing thing and as far as timing goes my car still has the half moon for the cas can only install it 1 way. And my mechanical timing is 100% correct I posted photos above. Confirmed with the balancer on and off.
