you will need to change the original fuel pipe as well as adding the return it is important that it has an 8mm (5/16) bore.

That's all before considering the engine and gearbox.

engine and gearbox are the next things to spec 1380 avonbar turbo kit engine plus SCGBox not sure what cams would be best and whether or not to high lift roller rockers any suggestions on engine specs folks (dont want to use a decomp plate)

get a head offset exaust valve at something like 32mm, and a inlet valve around 36mm double valve springs and fully ported. roughly 23.5cc chambers. with idealy 1.5 roller ratio titan rockers, there are ideal however swift tune roller rockers would do the trick. you can use standard push rods.

cam wise i would be looking at a fast road cam something for isntance like a kend cams 276 however the 274 scatter pattern would be better.

then crank wise i would balence lighten and harden and cross drill.

rods would be lightened shot peaned, polished then balenced end over end.

i would be useing forged omega 7cc offset bowl pistons.

vandervall bearings all round

vernier duplex timeing chain kit.

high flow turbo oil pump and a high flow water pump.

a steel flywheel and an orange diaphram and a lightened backplate.

and mega jolt.

with that spec id expect you to be hitting 180bhp. and it will have reasonable fuel economy if you dont keep your foot planted.


just make sure your inter cooler is efficent.

The kits tend to be fairly good value for money. By the time you've got your own block & crank etc machined, bought pistons, balanced the rods etc etc you could have bought a decent kit already machined, then just assemble it up.
What kind of spec are you looking for ? everyday driver ? track car ? fast road/weekend warrior ?

Whatever spec you're looking at, with a supercharger fitted you'll have more torque than any orange diaphram can handle. You'll need a grey & the AP rally/race plate.
To get the compression down to a decent level you'll need bigger than 7cc pistons & 23.5cc in the chambers to. For example on a 1293 fitted with 15cc pistons you'd need 25cc in the chambers to get the compression down around 8.5-1.
As for a cylinder head i can pretty much do whatever you want, including the offset 36-32 suggested above. It depends what you're looking to achieve really.

i must be doing my calculations wrong that gave me a 8.3 compression ratio.

and thinking about it a slightly smaller inlet valve would be better maybe a 30mm.

Fast road with a little weekend warrioring would be good.
i must admit the kits look a very very good price thats why i mentioned them however nobody does a turbo kit with dished pistons. what overall volume do i need for the compression ration required (most people seem to recomend 8.5:1) what overall volume is this (i pressume 40cc per cylinder 25 head+15 piston) would idealy like to go 1340/1330 with a reasonably easy going cam and st 3 big valve head maybe 1.5 roller rockers, turbo oil pump, gray plate clutch, belt timing and a SC Gbox

can anyone recomend a kit to suit and make any further suggestions on spec

the hotek kit is your best bet its expensive but its worth the money all you need then is

  • stright cut gearbox with a 4 pin x diff and stright cut drops (guessworks is your friend here)
  • turbo/supercharger bits
  • head from turbo phil to match.

and all the gubins like starter motor ect and flywheel/clutch.

and when you get bored of the 15psi from the super charger put a turbo kit on the back and crack up the boost and youll be hitting 200bhp.

go for a 1293 as you will still retain room for a re bore in the block

put another 600 quid away for your gearbox too should handle 200bhp.

mines a little bit more then that bloody dog boxes and lsd`s.

by the way. with a super charged/turbo charged mini you useually have to steer towards people when over takeing hence why im putting a lsd in mine at the cost of 500 quid.

alot easier to control in a super charged mini because everything is so much more progressive.
