I have put a t4 on my car & have my t34/63 up for grabs.
I have done about 100 miles with it ,it boosted fine with no smoke.It was running 22 psi when i got the car & then when the other engine in its donee about 70 miles running 28 psi holding 25.
It was fairly new on my car when i got it i have checked the wastegate there is a tiny crack on the countersunk bit where the wastegate seats but it dosent go by the countersunk bit & when the wastegate is shut you cant see it.
how much is this worth?
Also i have a forge grpA dump valve done 20 miles its splitting new cost me £100 i want £50 + postage.
I may ad a few bits to this as i am changing the spec of my car
