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:

    • I can see between the water jacket and cyl 3 there wasn't a hard line of combustion gas. It certainly appears that the issue is coming from there. Yes, checked the tension. All at 100ft lbs where I set them 5 years ago. These blocks can crack but generally when they have been over bored. Mine is only 0.5mm oversize at 89.5mm. They break between cylinders around the 91mm mark. No sign of that with mine. My gut feeling is the head gasket lifted a while back when the studs stretched and i bandaided it by retorquing the studs. It's finally let go.
    • My Nismo 1.5 churps a bit on reverse turns when cold, but besides that feels like a stock diff.
    • Yes, but, I paid cash and I'm pretty sure the receipt was in the bin 10 minutes after I got home Note to self, keep all receipts
    • Bunnings would have just handed you your money back on that one!
    • So, version 4 intake is on its way I was looking at these a while ago but at around $200 or more it was a little pricey for something that might not work, but, I had it in my watch list, but, I got a message saying it was on special, and I had a code thingie to use, it eventually came in at $120 delivered, so BAM, BUY NOW.....LOL I'll need to have a look when it arrives but I feel it will "look" better than what I currently have, as it comes with a PCV fitting, so I will be able to get rid of the alloy pipe that goes to the throttle body with the PCV fitting  Well, that's what the voices in my head are telling me  Oh, and this happened today Yeap, it was a Trojan, and it was cheap, so I headed back to the hardware store and actually spent a little bit more on a heavy duty,  one that was actually recommended by a plumber mate, a Cyclone one with a fibreglass handle that is actually rated for clay The broken shovel will eventually be "modified" into a short handle shovel
