Cars been running great bought a turbo smart boost gauge and boost tee. So now I'm running 16psi hehe so much more fun especially through first and second.
Also took it to the drag strip had 4 passes missed a shift in one and managed 14.4 sec on another at 154kph and a 2.1 60 foot so was a pretty good run over All. Now onto shocks and bushings

Hi,
Dont know if you fixed the bushes yet but in qld there is a company called fulcrum suspension that can rebuild all tein coil overs and are the distributers in aus. They also make poly urethane bushes for the gt4 and can fit them. I have the bushes but never put them in yet. With the shocks if you want standard replacement go with kyb, they make them. Good luck

yep i know about fulcrum the do my wheel alignment at $110 for all four corners.
just an update my bonnet scoop trim fell out i dont see how its possible but it did so im not fixing it just gonna save for a rc hood.
still running 15-17psi seems good a bit of smoke out the exhaust im assuming its fuel as it still back fires off throttle occasionally. fun car to drive to to much grip looking at sway bars to get a bit more tail happy

I fyou want to get a bit rear happy, get the whiteline rear sway bar and get a rear strut brace. Whiteline brace requires metal to be cut, C-one does not and there is one on ebay from chine for 100 that looks like the c -one. The sway bar on its own made it better but the brace tightens it all together wi the rest of the body. Would also really recommend getting a front strut brace. makes a massive improvement and also the cucsco underarm brace is good but may hit exhaust if 3 in.

see the car alreasdy has aftermarket k-mac sway bars front and rear so i thought it would be tail happy already.
any way i will look into bracing and a thicker rear bar.

im not sure about employment after uni at the moment so the gt4 is on daily duties and im just leaving as is until i know i have a graduate position then it will be suspension and aircon which i really want before next summer as the queensland 40'c days knock me lol i like the cool.
so hopefully sonner rather then later ill have some big updates right now im just getting from A to B on 15psi :evil: which is fun

for kicks i hopped under the car with some calipers and found the front sway bar is 27mm thick and the rear is 20-21mm thick so apart from adjustment there is no gain from another sway bar. maybe get a custom from 25mm swaybar but im really not that keen.
still now change in job status so car is staying a dd.

got a queery about boost control with a ct20b. i bought a boost tee which is a gated boost contoller, and i am getting a boost spike so i removed the ball and spring to get a less agressive boost curve and thus no spiking, im not getting spiking but not i get 15.5psi in first second and 16.5 in 4th 5th. now i disconnected the tsvs so it should be the same through all gears. what could be causing this? and finally it tapers of from about 5k rpm does that sound right?
fun car just boosting round

Really getting annoyed with this weird cooling issue I'm having.
Car runs fine no smoke nothing. Doesnt over heat compressions fine. But when turn it off it pushes coolant out it must overflow from the overflow and onto the ground. If it was overfilled it would to it all the time but it seems to only Do it when I turn it off? Any ideas ?????

Only other thing it could be is a coolant system leak somewhere.
Mine did something similar when i cracked the block :(

Not easily.
I thought it was a water pump or welsch plug leak.
Ended up using a friends boroscope to look around the pump & inside the timing cover to find it.

Mine was leaking coolant while running too.

Are you overfilling the expansion tank?
