Cam Specs?

SpOcK · December 12, 2003

Hi all!

I just recently registered - again - as I'm one of those whose accounts got deleted because of the recent mishap...

Now my question is as simple as this: does anyone know the specs for the 1G-FE cams? Inlet/outlet cam lift and timing, and when the VVT-i kicks in (around 4200rpm, right)?

Cheers,

SpOcK

p.s. to whom it may concern, thank's for the recent GB on dash trays. Got mine quickly and hassle free... :D

Don't have any info on the cams but VVT-i does not kick in. On that engine the inlet valve timing is constantly being changed throughout the rev range based on several parameters (load, speed, rpm, throttle etc).

Someone, Anyone? This piece of info I think should be found in IS200 "garage manual" Vol 1. I've got all the other three books, but not the Vol 1. You who got these books, could you help me out please...

I know this is a bit but as Colin said VVT-i doesn't kick in , what you feel 4200 is the ACIS valve in the inlet plenum opening , which isn't controlled by the cams.

OK, and ACIS valve controls the length of the inlet manifold, right? And the length of the manifold is altered to achieve good torque on lower rpm with one manifold length, and the other with high rpm?

But someone has to know the cams lift and other values?

I need this info to calculate the best possible exhaust manifold in quest for more power...

Tdi are looking to reprofile/improve mine (have spare engine)

PM TDIplc for more info he may be able to assist .. do a deal

I'm happy to be the guinea pig will be in January / Febuary tho

Yes at just over 4000 rpm the manifold length is shorten. Also ignition timing is advanced at the same time which is why you feel such a difference.
