I really didn't wanted to open a new thread but I really don't know what to do anymore. My car is an 1994 TT JDM Bpu auto supra, 360hp on the dyno.
As far as I know it has a greedy intercooler, HKS SSQV Dump Valve and it's delimited.
So here it goes:
My car doesn't pull as it did at the beginning, turbo seem to kick after 4500rpm (when he wants) when it hits 1 bar but till then i get 0 or around 0.4 bar pressure. Kick down works just fine but the turbo seem to boost when he wants, if i don't get any boost, i floor it again and it seems to work (but ONLY after 80 km/h) In first gear I don't get boost at all, it just pulls very high.
I put it in TTC and found a bad VSV, from the wastegate, then she made 360 on the dyno. I changed the vsv ( and checked all other) but there is no change. I even did a Boost leak and found a big hole in a intercooler rubber hose, change it, STILL THE SAME!!
I mean there is no difference, my car made 1 bar exactly like before and it behaves exactly.... I am pretty sure I don't have any bad pipes because I couldn't hear any when I did the boost leak test. Till now, car worked very good, i even felt when the first and second turbo boost. Could this be a bad conection problem? or an ecu? Please help
Till now I did a boost leak test, checked all vsv, changed some hoses who looked bad.
Other details:
-engine gets a bit hot
-there is some oil spit from the BOV
-no error codes found
