I'm going to do the coils, valve guide seals, valve springs and retainers tomorrow and just for a sanity check, change the cam timing to a known good economy position. Should take about 4 or 5 hours if I smash it, lucky I've had a coles order today that included plenty of energy drinks!!!

It also was going brrr on the dyno yesterday over about 12psi so it fixed that too. Tried to crank some boost into it today and it hit 32psi at 3200rpm then hit the boost cut. Turned it down slightly but there's a godamn boost leak on the intake side somewhere, I can hear it and it isn't holding boost. It wasn't there before the rebuild so I've just gotta have a look at what I've touched and get it sorted. Also I remembered that I already replaced the valve stem seals so I ain't changing sh*t! Just another day in the life lol 1 Link to comment Share on other sites More sharing options...

Haha I was aiming for 25psi which is pretty normal, I will send the farker when the time comes, you can bet your whiskers 1 Link to comment Share on other sites More sharing options...

It appears to come on around 4000rpm so not terrible. Got a boost leak somewhere so gotta find that, it makes 10psi with 15psi gate spring so yerp. Also fitted my modified vct gears to the cams today, helps a bit with low end power. Link to comment Share on other sites More sharing options...

Vct immediately got unhappy so locked it out again. 50th time the rocker cover has been off this week Gonna have to use a smoke tester to find the boost leak cos I CBF pulling sh*t apart anymore. The turbo is making positive pressure at 3350rpm, not bad 1 Link to comment Share on other sites More sharing options...

I'll pull it apart for a look, might be able to repair it. Anyway I put a new TB in there so it's sorted, and I bought another one just in case I need a spare. Still wasn't making boost though...Haltech did an update and limited the throttle to 50%. That was a fun one to solve. Now that it actually gets full throttle the turbo is in positive pressure before 2500rpm. I've only done one quick run at 26psi with no timing in it but it goes like feck with that big arse turbo. Don't get me wrong it has some lag to it, but I can live with that and it's good enough to chop at roll racing. Will get it back on the dyno one day to see what I can do with it, maybe Saturday. 2 Link to comment Share on other sites More sharing options...

I've ordered a leak/smoke machine to check the hot side, so it will be interesting to see if there is a leak causing the high fuel usage. Lol it was hitting the 30psi cut on the shifts so I upped the cut to 35psi. Should be sorted in that area at least 1 Link to comment Share on other sites More sharing options...
