Stripped out the inlet manifold today.
Traced the steel gasket onto gasket paper thats 1.2mm thick. Cut it out. Put the 1.6 inlet manifold back in with the solenoid from the vim as it had the newer type seal.
All back together and no oil leaks.
Put the 2.0 throttle body on.
So now so far the mods are, v6 intake pipe, 2.0 throttle body and 2.0 cams.
Had a lad at work plug the car in and remove any faults. Then I did an ecu reset following a guide on here.
Result. The car feels so much better. No flat spots anymore. Pulls along nicely too. It definitly geys up the road quicker in 1st to 3rd.
Also took it on the motorway tonight and it got to 120mph with ease.
Im also happier with the 1.6 inlet back in because there is no more strain on the loom.
Next on the list is to get rid of the precats and see is there any more improvements then eventually a map.
