cute wee gem Posted February 7, 2013 Author Share Posted February 7, 2013 Bad oil pressure on start up escalated into blown big end. Oil pump looks ok so I'm not really sure why, probably just poor maintenance and too many skids? It was also really tired (275km) Made a pathetic 144rwhp last november lol and has always been had real bad compression on #3 Quote Link to comment Share on other sites More sharing options...

cute wee gem Posted February 25, 2013 Author Share Posted February 25, 2013 So the last week or two I've been doing some work on this shit heap. Cut out an exhaust flange first Budget drill press with CRC as cutting fluid worked a treat. All cut out, fitted and ready to port match Port matched to head and also to steam pipe size which is a little bigger. Mocked up turbo in the correct position Mocked up on the 1j for final fit. While waiting for the steam pipe bends to get here, I cut the plenum off the intake runners. Welded on a bit of plate, then cut some trumpets down. Welded the trumpets on, most of them warped a little but should be fine. Ported them to the runners. Wasn't as nice looking as I'd hoped, but it'll be covered by the plenum anyway. Steam pipe has arrived so the next step is to start the merge collector and I also need to buy some 4" aluminium tube for the plenum and a plate for the throttle body mount Someone donate me a mill and a lathe please, cause this shit takes fucking forever with my shitty tools. I'm also looking at upgrading the compressor size of the turbo to 60mm (up from 54mm inducer) the hot side is 12cm2 (roughly .89 a/r) so that should be sweet for my needs 3 Quote Link to comment Share on other sites More sharing options...

cute wee gem Posted March 10, 2013 Author Share Posted March 10, 2013 Made a little progress this week on the turbo manifold. Need to trim #1 as it's only 5mm from the strut tower. #5 is a little short and sharp, but there was no other way to do it as I needed space for the dump pipe. I'm trying to make a "proper" twin scroll setup, but I'm a little confused as to whether I should go for a big single gate, or twin gates? (space could be an issue) Thoughts? 2 Quote Link to comment Share on other sites More sharing options...

SHGWAG Posted March 13, 2013 Share Posted March 13, 2013 Twin gates, so your exhaust can get out the gate while it's out the gate!! Quote Link to comment Share on other sites More sharing options...
cute wee gem Posted March 3, 2014 Author Share Posted March 3, 2014 Just to show I haven't fallen off the face of the earth. I gave up on my inlet manifold after lots of hours trying to get it looking good, no matter what I did it was going to sit too high and either foul the bonnet, or just look strange. So I sold out and Aliexpressed a 1jz manifold for 145nzd shipped. The design is quite good with internal bellmouths etc but the finish work was obviously quite bad, which I was expecting and didn't really bother me as I hacked it up anyway. I started by chopping the runners off it halfway and bent them to line up with the 2jz runners, which I also cut in half and welded on, ported runners and tidied up the chineseness. I then cut the 90mm throttle flange off and welded on a 83mm q45 TB flange at a better angle to suit the low bonnet. Made brackets for throttle cable, -8an fuel rail and welded in injector bosses for the ID1000 injectors. Made a flange for the Holset and fully welded the exhaust manifold. Please excuse my tig skills Just started on the wastegate mounting tonight hence the big hole under the flange Lots of purchases made lately after selling the Gemini last year. I'll take some snaps when I start building the engine in a month or 2 or 3 or 12 Looks like this as of tonight. 3 Quote Link to comment Share on other sites More sharing options...
cute wee gem Posted March 3, 2014 Author Share Posted March 3, 2014 I like the look of the turbo sitting up nice n proud, unfortunately I'm a retard and started with a GE, so there's a gigantor distributor in the way. Good one dick. Could always run GTE electronics but I'm too far in to change now. Quote Link to comment Share on other sites More sharing options...
cute wee gem Posted March 4, 2014 Author Share Posted March 4, 2014 Got one gate mounted up today. These are also aliexpress specials at 130nzd for both shipped. Checked them over and they both seem to work sweet. I had good success with a china gate on the gem and I'm way too cheap/poor to pay 800+ for a couple of valves. I'll spend the money in more important areas & use an overboost spark cut if they do happen to fail. Couple of pics from tonight 5 Quote Link to comment Share on other sites More sharing options...

cute wee gem Posted April 13, 2014 Author Share Posted April 13, 2014 Balanced rotating assembly, ARP fasteners, ACL bearings, NPR rings. Stir and enjoy ARPs are kinda overkill for the current setup, but I may one day change to forged items and a bigger turbo for shits and giggles 2 Quote Link to comment Share on other sites More sharing options...
