I own a 89 TT, the motor has been completely rebuilt and is in great shape. However, the engine wont rev much past 5500 RPM. Starts sounding a bit like VW..just does'nt want to go higher.. Boost leak? Timing is 15 BTC.. Compression is 175 all round I talked to a friend who has a Zed and his revs easely into the red. Any thoughts?
adding injector/connectors and ptu to this list of Chili's start with the trick of pulling the coil connectors while idleing looking for the connector that does not make a difference to the engine lumpiness.
Problem fixed Thanks for all the input...I found 3 problems 1..A boost leak at the inter cooler hoses...was quite loose 2..Two fuel leaks ..loose hose clamps..lucky I checked..dont want to go up in flames! 3..Got rid of the stock air filter box and installed a pod filter Exhaust is a twin 2.5 inches system with X over It basically was a fuel and breathing problem. All good Revs up to 7300 RPM sweet as can be
That's strange....you didn't mention anything about leaking fuel, maybe the fuel your using is 'odourless'?
