Ian. Posted June 29, 2014 Author Share Posted June 29, 2014 The first thing I wanted to do was to replace the gauges with Defi units. By this point the Oil Pressure gauge had given up and the oil temp gauge was reading a constant 150 Degrees I changed the head unit & sub for something a bit more subtle I also fitted an Apexi intake, but the car didn't feel quite right with it fitted so I removed it and refitted the OEM box. Over winter I fitted a suede wrapped dash to replace the tacky CF wrap, Carbing gear knob, OEM speedo cluster, HKS AFK, a Personal steering wheel & a Cusco CF rear strut brace Quote Link to comment Share on other sites More sharing options...
Ian. Posted June 29, 2014 Author Share Posted June 29, 2014 Over the winter it had a lot of work done to it. Whifbitz Ridox front bumper Custom vented bonnet with aero catches OEM rear wing Full respray Carbon fuse box covers Cusco carbon front strut brace Syvecs BC 264 cams Titan Cam gears Sard 800cc Injectors Couldn't get any figures from the mapping session due to the dyno that was used.

Ian. Posted June 29, 2014 Author Share Posted June 29, 2014 Finally took it for a dyno & pulled a miserable 319WHP. Disappointed was an understatement. The dyno operator said that it was miss firing as soon as it came on boost which is why it was down on power. It boosted to 1.3 bar fine, oil pressure was OK, AFR was OK, Oil temp was OK if not a little high at 110 degrees. I took the car to my good friends at 360 Motorsport to get their opinion on it. Coils checked out OK, Plugs were black & wet. Next step was a compression test. Cylinder 1: 155PSI Cylinder 2: 150PSI Cylinder 3: 160PSI Cylinder 4: 120PSI Cylinder 5: 150PSI Cylinder 6: 155PSI Have been considering my options for the last few days but after spending a few hours up there yesterday discussing my options it has been decided - I'm going to rebuild the Supra. Current Build Plan Rebored block Wiseco Pistons Eagle Rods Titan Oil Pump ARP Bolts ACL Bearings OEM Water Pump OEM Gasket kit Headgasket ***Still to be decided**** Powerhouse Racing street torque turbo kit Clutch **** to be decided**** Oil cooler Bosch fuel pumps With Swirl pot Battery relocation Electric fan kit Tomei/TRD LSD ***If theres any money left in the pot**** Bigger brakes (Aslong as they will fit under the LM's) Plus any other little bits & pieces I fancy along the way. Still working out the full build list but the bottom end is pretty much decided on Target is 650-700BHP Engine is coming out tomorrow ready for the strip down Quote Link to comment Share on other sites More sharing options...
jimojameso Posted June 30, 2014 Share Posted June 30, 2014 Sorry to read at your troubles mate. I'd be interested to know what has caused the loss in compression. When i owned the car all the cylinders were slightly higher than those readings you have there and cylinder 4 was fine. Nice to see your going single on it though! Get the bay painted while the engine is out!! That's something i always wanted done Looking forward to seeing this done and btw i liked the tackey carbon dash Quote Link to comment Share on other sites More sharing options...
Ian. Posted June 30, 2014 Author Share Posted June 30, 2014 Haha. I love carbon but hate it on interior parts. Engine bay will be getting painted satin black to match the underside of the bonnet. We think its piston rings but will find out this week when the engine comes out Quote Link to comment Share on other sites More sharing options...
Luxluc Posted June 30, 2014 Share Posted June 30, 2014 That is the only reasonable option if you have that low compression on one of the cylinders. Get that thing rebored, rebuilt and that turbo on What clutch do you have in mind? JamieP tried the new HKS and said it was perfect for a street car.

Ian. Posted June 30, 2014 Author Share Posted June 30, 2014 Im looking at Spec clutches & exedy clutches at the moment. Will take a look at the HKS one nearer the time Quote Link to comment Share on other sites More sharing options...
Mario Posted June 30, 2014 Share Posted June 30, 2014 Best of luck with the build. Quote Link to comment Share on other sites More sharing options...
abtin90 Posted June 30, 2014 Share Posted June 30, 2014 Nice build, glad you decided to keep her. Those hybrid figures seem really good what boost did it make that at? Also are you doing the single conversion yourself? Quote Link to comment Share on other sites More sharing options...
Sheefa Posted June 30, 2014 Share Posted June 30, 2014 (edited) Gutted to hear this Ian mate, but glad you are going to rebuild her. She never put a beat wrong under my ownership or James' either. Here was the thread from when I got her dyno'd and the graph. She made a healthy 335rwhp at 1 bar as I just wanted to check the AFR's and Boost Levels. http://www.mkivsupra.net/vbb/showthread.php?280288-That-s-a-better-Dynograph-! Let us know the outcome of the engine strip. Best of luck bud Greg Edited June 30, 2014 by Sheefa (see edit history) Quote Link to comment Share on other sites More sharing options...
Ian. Posted June 30, 2014 Author Share Posted June 30, 2014 Build is being done by 360 motorsports. They are building the engine so might aswell do the rest of it. My AFRs, oil pressure, oil temps & boost pressure were all as they should be - it was just missing about 80hp Quote Link to comment Share on other sites More sharing options...
Ian. Posted July 9, 2014 Author Share Posted July 9, 2014 Been up to check on the car tonight & collect a few parts off it to sell & raise some funds for other bits. Engine is now out of the car & mostly stripped. Piston in cylinder 4 is showing signs of det & looks as if it starting to melt. Pistons will be out tomorrow & we can further assess the damage. Cylinder head is off & all the valves are white except for number 4 which are black. Once everything is stripped down then the bottom end will be: Wiseco Pistons Eagle rods Titan Oil pump New OEM water pump All new OEM gaskets ARP bolts ACL bearings Although we are looking at maybe changing the piston/rod combo to a Wossner/Tomei setup. Picked up a few other parts aswell this week TRD Thermostat TRD Engine mounts TRD transmission mount OEM engine mount brackets PHR anodized pulleys & water pump cover SRD Intake manifold Spec clutch Whifbitz catch can BW S366 turbo kit (Picking this up on saturday ) Should be a couple of months getting the bottom end built up to give me time to save to get a built head aswell. Decided to stick to 264 cams, we think 272s will effect the low speed drivability a bit much Any thoughts on the best head gasket to use? Was thinking either HKS or Cometic unless OEM will be up to the job? Also any thoughts on the current/potential piston/rod combo? Quote Link to comment Share on other sites More sharing options...
Chris Bailey Posted July 9, 2014 Share Posted July 9, 2014 Good luck with the TRD engine and gearbox mounts, I've heard other members say they can be very loud. Quote Link to comment Share on other sites More sharing options...
thetrashcanman Posted July 9, 2014 Share Posted July 9, 2014 Good luck with the TRD engine and gearbox mounts, I've heard other members say they can be very loud. Good choice on the turbo kit Not thought about Mahle or CP pistons? Quote Link to comment Share on other sites More sharing options...
