ZT-R Posted October 6, 2012 Author Share Posted October 6, 2012 Doing some more mockup today. Looks like everything clears fine. Downpipe has plenty of room, cept for the closed loop part. Quote Link to comment Share on other sites More sharing options...

ZT-R Posted October 7, 2012 Author Share Posted October 7, 2012 Well, thanks to my ADD I didn't get much done today, lots of tinkering but i did manage to get the oil coolers mounted up, glad that's over, I hate fiber-glassing. They are kinda small but i think it will be ok. 3" tall x 7.5 wide x 2 thick X2. I will probably make brake ducts on the back side of them once she is up and running.

RB26powered74zcar Posted October 8, 2012 Share Posted October 8, 2012 Great use of the openings! Looks like they they will do a good job @ cooling. Quote Link to comment Share on other sites More sharing options...
Rywats Posted October 8, 2012 Share Posted October 8, 2012 I agree. Very efficient use of space. Should do the job proper. Quote Link to comment Share on other sites More sharing options...
Vintage-TechZ Posted October 8, 2012 Share Posted October 8, 2012 Great placement for twins. I had planned on doing something similar only placing them back further with ducting and at more of an angle to avoid rocks eventually stabbing pinholes. Down low on our cars they can get pummeled there. Quote Link to comment Share on other sites More sharing options...

EF Ian Posted October 9, 2012 Share Posted October 9, 2012 Love how its looking so far. What kind of response/lag do you expect with this setup? I still plan on going RB26DETT and while I like the idea of twin turbo for good response it would be far easier to get it all fitted in with a single turbo setup but I'm not sure I could put up with the lag (I'm used to highly tuned NA motors) I'll only be looking for around 400hp so at least I can go for a smallish turbo. I've driven a 650hp Evo 7 and while the on boost performance was crazy it hardly moved before 3500rpm and on the road I find this annoying. My mates RB25DET is nicely responsive but thats from the small turbo which at 300hp is reaching its limits. How do you find your low end performance?

ZT-R Posted October 10, 2012 Author Share Posted October 10, 2012 Sounds like you will want the 2859r turbos. Robbie said this setup should see 1 bar at 3000. I'm kinda expecting more like 3500. Ive seen graphs of this setup and it has about 400 tq around 3200. Quote Link to comment Share on other sites More sharing options...
ZT-R Posted October 14, 2012 Author Share Posted October 14, 2012 waiting on parts from supertech... Ordered parts from supertech. 1 week later i ordered RB30 from RIPS in new zealand. Had some custom CP pistons made and all this other crap, shipped over here, ready to go and still waiting on fuckers at supertech. Sad...

ZT-R Posted October 20, 2012 Author Share Posted October 20, 2012 Well, I have been tinkering some while waiting for parts. Forever waiting on supertech, jesus. Well I welded some bungs for a oil drain from the head and oil temp sensor. Got the pan all bolted up and was putting on the AC bracket when i noticed the oil pump wasnt sealed all the way. I torqued it and didnt think much of it. Well, anyway I had to do a slight modification to the block to clear the Tomei oil pump because it is so much bigger than OEM. If you notice, the rb26 doesnt have the circle cast at the 2 o'clock position. It hit the tomei pump here. Terrible picture, but i ground down the circle and had some clearance putty to make sure everything was clearing. Also tapped the rips manifold for 3/8 npt fitings for idle air and FIC control. Working on shimming the cams now. Still waiting on shims. errrrrrr Tinkering with some micrometers. Quote Link to comment Share on other sites More sharing options...

ZT-R Posted October 21, 2012 Author Share Posted October 21, 2012 Well had to work all day today so I didnt get much done. But did get to make some adapters for the knock sensor. The RB30 has a 12mm extra fine thread knock sensor and the RB26 uses 8mm. Not sure what I will work on today. Maybe some AC wiring and run a 10an fuel line. This 8an one has me nervous.

rzamvilla Posted October 29, 2012 Share Posted October 29, 2012 Goodness, great build and great photography nonetheless! By the way, what exhaust manifold studs are you using? Quote Link to comment Share on other sites More sharing options...
EF Ian Posted October 29, 2012 Share Posted October 29, 2012 Really loving this, engine looks awesome. Should be a great setup with all thos parts, rips manifolds, endyn worked head, several tomei parts. Can't say I'm not jealous. Was rob able to make the exhaust manifold from dimensions he had from when he ran a 240Z? Quote Link to comment Share on other sites More sharing options...
