that SC setup has no blowoff valves so potentially a grenade.

Why would it have a blow off valve? if it did it would be blowing off fuel/air mixture into atmosphere. If you get an inlet backfire the belt just slips.

not that a ribbed belt with no spring back tensioner.

nah D my setup has all made its way up into NSW now to live on in another 1200 on this site
$5000 wouldnt have been able to build that engine though
so at just over half that the new owner got a nice bargain

New owner will be getting more tickets by the sounds of it :)

haha i never managed to get any tickets in it, got pulled over once right before i took it out to put the CA in and even though i did some WOT over taking infront of the cop car they didnt feel the need to pop the bonnet
nearly got banned from uni first time i drove to uni with that engine in the sedan though

i was considering on turboing the A12 but would a supercharger give me better low end performance? i would like to get more grunt out of the engine. where about is this jeff taylor guy located. i live in brisbane. i was also wondering where in brisbane is there a guy that is good at working on these types of engines?

Whatever you do with boost, you will have to engineer your ute and considering
you have to do that you might as well put in an L series to save on gearbox costs
and availability. You could go an L18 with L20 crank and round port Z20 head for
with ports moved up and you have a crossflow engine that loves boost and the L18
and Z heads are shorter than L20 block and L series head for fitment.
There is Gary (Lemonhead) who is up your way and has most machinery at home to
do work that youll be blown away by.

The Z heads can take bigger valves than an L series and have the pro-swirl
hemi-like chamber perfect for boost or higher compression combos.

They are available still in new castings for overseas markets and the z20
head as mentioned has more potential for flow with z24 valves. The ports
can be tigged up at the top and ported to oval as indicated in the green
or D ported with rounded square top and left round at the base as standard.

standard L18 with boost would be plenty, no real need to swap and change stuff

more worth while spending that time and effort making the turbo setup better
