Yonz Posted January 29, 2017 Author Share Posted January 29, 2017 Yeah pretty much, it's an interference fit. The fitment of the pump needs the locating dowels on the block removed as well.

Yonz Posted October 18, 2017 Author Share Posted October 18, 2017 Update time! Engine is running again and I changed a few things up while it was apart: Switched to a Hall Effect setup for timing, very similar to the setup @HarrisRacing has (Thanks again for the clarification on the wiring mate) Running a Holset HX40 from TurboLab instead of the ProBoost GTX35 Had the head ported while it was off Degreed the cams Drilled out the oil drains to 10mm Made a swirl port and larger header tank Working speedo and a battery isolator Threw in a NPC clutch Heaps of other little things went on but those were the big time killers. Anyway, onto the pics Before fitting the new pump I picked up a busted one for free, which I used as a template to make a bracket for the crank trigger (busted pump not in pics) Took a couple goes to line everything up and still have it clear the balancer, but I got there eventually Tapped a M12 x 1.0 thread into the left support bracket, and just using the 2 supplied slim nuts on the other; all with Loctite. That 12T wheel is from Hi Octane Racing About 2-3mm clearance for the balancer at the closest point The guts of a gutted and free CAS housing rocking a GT101 sensor Managed to use all of the existing bolt holes to secure the sensor itself and fitted the other one just to keep water and whatever else out. Only needed a bit of smoothing out with the die grinder to get it to sit level. Then chopped up a bit of 6mm plastic to secure the body of the sensor and clamp everything down; again Loctite on everything. Didn't really get any pics of the bolts on the cam but it's basically the same as Harris. Grinded down the standard bolts, then got a longer M7 bolt and spaced it out with one M7 nut and 2 (from memory) 1mm washers. All with Loctite and also grinded the bolt face smooth so the letters aren't causing dramas. More for my reference but I'm sure someone else might find this handy. Header tank and swirl pot ready for paint. Already made the brackets and made sure they'd fit, also leak checked. These were more of a welding practice project but I'm happy with how they turned out. Fair bit bigger than the little cylinder ebay items and used all the available space without going too crazy. I have all the dimensions for this if anyone wants them. Swirl pot sitting pretty too. Does clear the bonnet, but only just haha Using a Acewell 3100 dash for tacho and speedo, this is the supplied speedo sensor fitted up off the tailshaft centre bearing. Had to cut and tap a sleeve for the magnet to sit in, probably would have flung off otherwise. Got it to within 5k's for the moment, will dial it in a bit more at the next track day. Holset HX40 sits very nice in the bay, only needed to change the oil drain a tiny bit for it to fit up Most of the hard work done Finally fitting up the BOV, welds slowly improving too All finished! For now anyway 4 1 Link to comment https://www.sau.com.au/forums/topic/453076-r33-rb30det-drift-build-in-the-nt-350z-6-speed/page/4/#findComment-7854942 Share on other sites More sharing options...
Dale FZ1 Posted October 18, 2017 Share Posted October 18, 2017 Good effort with the crank angle sensor setup. What's the expectation with turbo change to the HX40?

Yonz Posted October 18, 2017 Author Share Posted October 18, 2017 Thanks Works a treat and can't complain for only $400 Basically the closeness of the turbine blades to the housing is what grabbed my interest, the old turbo had an easy 5mm gap. See vid below for what I mean. A few other things went into my decision but compared to the old turbo, this Holset is better all round. Old setup on the left, new on the right. Boost coming along a lot earlier despite the turbos being very similar in wheel sizes. Admittedly the head being ported would have had an impact in this as well, but not nearly 1000rpm worth. Also the hall effect sensors have visibly cleaned up the power curve. FYI, I rate PITS and ASG very highly. This pic is not about comparing the 2 shops, simply observing the difference in engine behaviour between my 2 setups. 1 Link to comment https://www.sau.com.au/forums/topic/453076-r33-rb30det-drift-build-in-the-nt-350z-6-speed/page/4/#findComment-7854991 Share on other sites More sharing options...
klutched Posted October 18, 2017 Share Posted October 18, 2017 (edited) Looks good! But are you going to screw more into it? If not why such a big turbo for power a gt30 can easily make with a lot better response?

Yonz Posted October 18, 2017 Author Share Posted October 18, 2017 It's all set for E85, so once I commit to that it will really shine But at the moment going to E85 is a bit of a pain and I'd like to have a better clutch and the GTR rear end fitted ahead of time, which is more money and time. I just want to drive the thing again for now Link to comment https://www.sau.com.au/forums/topic/453076-r33-rb30det-drift-build-in-the-nt-350z-6-speed/page/4/#findComment-7855025 Share on other sites More sharing options...
Nistico Posted December 26, 2017 Share Posted December 26, 2017 (edited) Hey mate just on the diff ratio youre using, does it feel spot on or do you think something a touch shorter like a 3.7 would be perfect? Im about to put a cd009 in my rb25 r32, from what iv read the gearbox ratios are nearly the same as an r34 gtr 6 speed and they use a 3.54 diff ratio i believe Edited December 26, 2017 by Nistico Spelling error Link to comment https://www.sau.com.au/forums/topic/453076-r33-rb30det-drift-build-in-the-nt-350z-6-speed/page/4/#findComment-7863375 Share on other sites More sharing options...
Yonz Posted December 26, 2017 Author Share Posted December 26, 2017 (edited) Yeah a 3.7 or 3.6 will definitely be the sweet spot for it IMO On 22/07/2016 at 8:14 PM, Yonz said: Also...
