basically the 4agte will be easier to engineer into the car
but if ur after some crazy power, then id recommend the 13b turbs
theyre 155kw/200hp flywheel stock
and are good reving engines and do 13s with stock setup turbo engine
jus thow on a nice hybrid t4, some boost, an extend turbo port, and ul kill anyone on the road.
by the way dude, i added a couple more pics of the engine bay on my site, where u can see the mounts.
