Mine is a hair off as I did a bunch of turbo disassembling and reassembling, and although I marked it, the comp cover did end up pointing toward the engine a little bit more. Chra is lined up though obviously. I think it'll max out the fuel system with no exhaust but I guess we'll see. Link to comment Share on other sites More sharing options...

I can't actually remember when I first saw it loose but I'll say 3-5yrs ago. I've never been able to get it properly tight as there no access and from memory I used a modified pressed steel tool from a router or some other chinesium power tool to tighten it up.

bjc Donating Members 2,823 Member For: 21y 2m 12d Gender: Male Location: Townsville Posted 14/08/20 04:31 AM Share Posted 14/08/20 04:31 AM Water line from the thermostat area goes to the exhaust manifold side, oil on top with the white paint mark.You can see the choice loose bolt on the left next to the banjo fitting...What way does the water go into the turbo? From the thermostat area or the back of the water pump? I'm questioning whether I should change the IC piping to alloy instead of stainless as I think it's retaining the heat in the pipe? Intake temps seem to point to that or because of my MAP sensor location it's reading the SS's radiant heat???It would be an expensive test just to see though as I cannot weld alloy...

What intercooler do you have? What are your iat's? Link to comment Share on other sites More sharing options...

It's fairly big but haven't got the front bumper off yet to measure it. Very similar to the Rapid cooler size (thicker I think?). IAT's are generally 10-12°C above ambient and ambient temp was 29 when I last drove the car. It's generally after I've driven to the shops (coolant only gets to 70 at most on the trips from home) and parked the car for 20+mins then start it back up. IAT's are at 45°C from then and unless I give it a squirt on the trip home (60km zone) it'll stay at 42-44 regardless. This seems to be the case even when the ambient temp is colder around 24... Thermostat is an 80 or 82 and fans come on at 82 and off at 80, trans stays at or below 80 with the stock heat exchanger still.I've built an air filter box out of corflute atm before I settle on design and thought it was because the SS hot side goes through this area that it was holding the heat but I wrapped it in "quality" silver insulation air bubblewrap from hello fresh (food delivery mob) and it made no difference which I'm glad I didn't exhaust wrap it first now!Summer heat will come soon as the temp is all over the place atm so if it goes to 60°C like it was without the airbox then I'll have to keep testing. 1 Link to comment Share on other sites More sharing options...

There's not a lot you can do when it's 35c+ every day. 1 Link to comment Share on other sites More sharing options...
