brett_qld Posted July 31, 2015 Author Report Share Posted July 31, 2015 850cc injectors mounted, sr20 rail made to fit. They should give me some headroom for more boost later. Plenum is done, I got a little carried away on the top cover ;-) 1 Quote Link to comment Share on other sites More sharing options...
oh what a nissan feeling! Posted August 2, 2015 Report Share Posted August 2, 2015 (edited) I believe a plenum should be a minimum of double the engine volume, so at least 4L for a big bore 3t (~1950cc) not sure about the max volume? The bellmouths / trumpets should never be flush with plenum wall / floor, they should be raised. The reason being the slowest moving air is always at the boundaries of a plenum / pipe and the fastest at the centre. These might be too long, but they are the shortest dhla/dcoe ones I could find. The 4th cylinder opening is roughly half way in the plenum. Ideally theyd be slightly shorter and have a full radius instead of half radius. Plenum volume can be between 1 and 2 x the engine capacity, 2 x usually used on engines producing well over 2 hp per cc. Hypertune plenum handy little chart, number 11 is what i was referring to.

brett_qld Posted September 5, 2015 Author Report Share Posted September 5, 2015 Thanks mate, I remember seeing a chart similar to that quite some time ago, I guess these trumpets would be closest to #9 with the back edge of #3? Quote Link to comment Share on other sites More sharing options...
brett_qld Posted September 5, 2015 Author Report Share Posted September 5, 2015 Been a while since I've posted. Put some solid hrs into getting it running but had a run of bad luck. Had an injector die, bricked my ecu, lift pump failed and wideband died. Despite that, I got it running (no wideband at time of video) yet to tune it.

brett_qld Posted September 24, 2015 Author Report Share Posted September 24, 2015 Made some pretty big changes, removed the coils and igniter module and replaced with logic level COPs to diagnose a miss / breakdown of spark. But it turned out that I just needed a 10k resistor on my VR sensor... ah well. Ive also changed the turbo to a gt2560r, running a techedge O2 controller and switched to e85. Have road tuned it and its hauling ass, quite easy to break traction in 4th without much provocation. Very happy with the results, the only thing holding me back now is the clutch can't cope with the big increase in power. I have a 1g-gte 225mm flywheel and bellhousing and a w57 here for it. I have gone with CI's ga70 225mm sprung button clutch. This setup should be spot on. Quote Link to comment Share on other sites More sharing options...
oh what a nissan feeling! Posted September 25, 2015 Report Share Posted September 25, 2015 2560 and e85 is some nice progress, will be a little weapon. Quote Link to comment Share on other sites More sharing options...
brett_qld Posted September 26, 2015 Author Report Share Posted September 26, 2015 Thanks mate, even at 8psi its already a handful. Once this clutch is in I'll bump it up to 14. Quote Link to comment Share on other sites More sharing options...
Doogs Posted August 31, 2016 Report Share Posted August 31, 2016 Damn this thing is cool! Great work on all the changes since the NA setup, any updates? Quote Link to comment Share on other sites More sharing options...
brett_qld Posted August 31, 2016 Author Report Share Posted August 31, 2016 Hey mate, yeah lots and lots of work since. I'll put some updates up once I get a bit more time, but for now I'll just put up a picture :y: Quote Link to comment Share on other sites More sharing options...

brett_qld Posted August 31, 2016 Author Report Share Posted August 31, 2016 (edited) A few updates for you guys. Built a side pipe for it, this is it idling. Edited August 31, 2016 by brett_qld Quote Link to comment Share on other sites More sharing options...
brett_qld Posted August 31, 2016 Author Report Share Posted August 31, 2016 First time drifting it since the turbo conversion, track was really wet. Quote Link to comment Share on other sites More sharing options...
brett_qld Posted August 31, 2016 Author Report Share Posted August 31, 2016 Later in the day, drifting in the dry: Testing the rear bumper cam It violently transitions between traction / no traction and over / under steer, I think mostly due to the spooled diff. Makes for a pretty fun ride :D Quote Link to comment Share on other sites More sharing options...
brett_qld Posted August 31, 2016 Author Report Share Posted August 31, 2016 And this is the actual turbo setup being built for the 3tgte, a Garrett GTX3067R Twin scroll 1.01 rear housing. Aiming for a lot of boost, hoping to hit 400rwhp :D Quote Link to comment Share on other sites More sharing options...
