intake manifolds are different on all of them , even the L28 and L24
the L20et intake mani has smaller longer runners to increase intake charge velocity, so is very good for torque,(on a 2 liter anyways!)
The L28 is bigger on most models, but they changed it a few times....
THe L24 is in the middle, good balance of torque and higher RPM power... I will be useing my stock L24 intake for starters, then change to L20et later on to see if there is much difference.
the turbos that i have available to use are a VG30, not too sure if its stock as it looks like a RB20 compressor cover. the other is a high flowed VL turbo unit (still to take delivery)
Both of these will be boosting around 3000rpm and above, so my intake manifold should be ok for off-boost driving.
Old man in the hills may be going to a dementia ward soon, so im not too sure how long it will be before the grandkids attempt to clean out his shed!
and not to worry as i have enough conversion parts to last me quite a few years.... just gotta save some cash to et the hatch regoed then i can bolt on all the goodies!
I have a L20et head, block, crank and a few other bits in the carport ready for the scrap metal yard.... so if anyones keen let me know!
