For higher rpm you want a 1.6 L crankshaft,1.6 camplate and 9mm plunger/head!The 1.9 crank and camplate limit rpm with the 1.9 and with a bigger (10-12mm) plunger/head it only makers it worse.9mm will make lots more fuel than the engine can take anyhow.
The 1.9 engine has a longer stroke and this is the main restriction for higher reving when compared to the 1.6 same thing with the different camplates.However what you loose in revability with the 1.9 you will still benifit from the higher torque and larger displacment IMO.1.9's can be built to perfom well with the limiting factor to both engines being the head and keeping it on the block! As long as you dont plan on making any more power than than a k24,t3 or GT20 can make then you might be ok if your lucky.With the IDI's higher CR and weaker head than the TDI we can't make as much power without issues unfortunately :cry:.
170hp from internally stock 1,6 is piece of cake. Stock manifolds are ok, K24 is too small for that.
Quote from: "MJF"170hp from internally stock 1,6 is piece of cake. Stock manifolds are ok, K24 is too small for that.Really?! Do you have any head gasket problems? How high are you running your RPM's to?
dont know how you do it. I just cant keep it from lifting also Andy2 is having the same problem.... Do you mind sharing some specs on your setup? and 170 crank is an estimate i G teched my car at 134 net hp.
