i think they had the hydraulic clutch g/box karl RS5F70 ? but i think the block is the same size as GA.
paul (polly) has a link to one guy,s megga hp QG18t build
a QG transplant would be easier in a coilpack k11 karl, they have far more similarities (starter under the mani, same flywheel shape, coilpack ignition, same maf/crank sensor/cam sensor)
Complete loom change and dash and column tho eh karl, different ecu plug and main fusebox etc.
And the mot man has to log the engine code into the datebase dont forget
