Help with friends DIY turbo civic.
Hey i know its the miata form, but im the only one out of my friends who knows anything about turbo setups (sad, i know) and i really cannot figure it out.
Its a honda B18b integra with a diy turbo setup on it, it has a t3/t4 turbo setup with a turbonetics delta external wastegate. It has a greddy type-s bov, and a badass FMIC. The piping seems to be completely cherry.
Well as of last night it was boosting strong, about as strong as me on 8psi of boost. His wastegate is set at 7psi. No problems.
It was boosting super hard at about 3krpms for a good 5 pulls, he decided not to boost it anymore as we go through town, we ate at sonic, then on the way home he punched it and nothing really happend.
The car now makes a spooling noise, and a long pshhhhhhhhhhhh but no boost built at all, and no increase in power. It is not the bov, weve completely ruled it out, we are leaning towards the wastegate...
Also as of today, i was under the car and i noticed oil leaking out through the downpipe where it connects to the turbo, this struck me as very odd.
Again, i know this is MIATAturbo.net, but i really trust most of you guys since youve all helped me out so much.
Thanks a ton, Nate.
