didn't know it earthed through bracket.
might copper grease the threads up to all coil and bracket bolts to aid earthing in a vauge hope it helps.
And it was a Toyota coil not an aftermarket one I hope for what ever Rev your car is
Sorry a Lucas one![]()

I am running on a very tight budget at the moment.
If I could have afforded a toyota one I would have.

Belt was mega tight fit.I had to take tensioner off, put it round pulleys and then re-install tensioner, the pin fell out of tensioner more or less once it was bolted on as pulley was pushing hard against it.
I replaced coolant pump and idler pulley as well
- Both were exactly the same as the ones that came off the car.
I checked the belt by counting the ribs and it is defo the earlier longer belt.
was a complete A@£3 to install.

It hesitates badly.
It was however overbooting
(20psi) on way home.
I assumed the guy had the MBC wound up too high.
Even if it wastegate didn't open properly why will it not boost till such high rpm then all come at once? Downpipe getting in way of wastegate shouldn't stop it boosting at 2500-4000 rpm should it?
If The wastegate rod got knocked upon installation of turbo back on car maybe wastegate is open then when it does kick in the downpipe makes it overboost..
.
Im going to go grudgingly take my down pipe off and check.
Hate that job one bolt is a real pain in the
- bleep bleep bleeeeep bleep bleep
- to take off.

Think I need to invest in one of those tools you pump by hand to create vacuum or pressure in pipes to check them.Would be massively usefull right now to check wastegate operation.
Almost bought one off snapon a month ago as well but thought noooo when would I use that, grr.

issues before I fitted my hks vpc
(afm delete).
For me the problem was the afm.I had to run the car with the afm screw all the way in or it would tick over at 300/400rpm or just stall

.
Other times my car acted like this it was a vacuum leak or air leak between the afm and turbo.also check for a leak between the idle control valve and afm.
basicly look for anywhere unmetered air could be getting in.

I originally timed belt up to the marks on bearing caps then had to take belt off as water pump was leaking(had used blue silicone sealant) have now put toyota pump gasket on and timed it up to plate marks.
Will remove rocker cover and double check.
In this pic wastegate is definatley closed, you can see clearance is minimal between downpipe and wastegate.Anyone know of toyosport downpipe issues?

Ignore the light patch top left of exhaust thats where i touched it.I can't see any marks that would suggest wastegate valve touching downpipe.
Would it be an idea to get a dremmel with stone attached to downpipe and grind a couple of mm off where valve is?

Thanks for feedback so far by the way everyone.I'm always grateful for the good and prompt feedback on here and frankly this succession of problems is doing my noodle in so I need all the help I can get.
