How are people fitting the Ljet intake manifolds to work with 2.0L heads? FWIW this will be on my 2056.

Seriously though if you have 3 bolt heads and 4 bolt runners you will have to modify your 1.8 l-jet runners or swap your heads. If I recall the 2.0 runners are going to come up short and in the wrong position to work properly with the 1.8 plenum. You could probably adapt them with soft hose or physically modify them but I suspect using modified 1.8 runners would be a cleaner setup. 1.8 and 2.0 runners are the same ID so you are not losing anything. |
