Hi guys,
I am a newbie so here goes, I have an R33 GTST with an RB25DET in it. Now here is the tricky part, had it rebuilt 30, 000kms ago (spent shitloads mind you) and now it runs like a hairy goat.
Modifications are as follows:
Front Mount Intercooler
3.5" Turbo Back Exhaust
Did compression tests and now no. 5 cylinder has 50 PSI and the rest have 150 PSI on an average. Now in the rebuild, apparently i got a pretty good one due to the fact it cost me around 10 big ones so as you could imagine i am pretty pissed of this is only happend as the garuntee has run out and also when i try to ring the workshop the number is disconnected. this workshop was recommended by the warranty company but i have come to the decission that i will do it myself this time round.
I have mechanical experience, but not when it comes to things like this so i was just wondering if any of you guys out there have come across something similar and if so what was the problem and then the solution.
Obviously every car is different but i just want to know what a may be looking at before i go pulling it all out.
Thanks in advance
Martin
