the mirage kit is a straight fit, no bulkhead mods needed at all. there's a few people on here with them aswell as the company that makes em :)

you'll need to change from your n/a carb and dizzy to turbo ones. you'll still need to do all the fueling mods and take out your old fuel pump and put the oil return in there.

engine wise what CR are you running? guessing its around 10:1 ish? you'll need to drop it down a fair bit if is high comp. easiest way is to open the chambers up in the head or get some dished pistons. Not sure on whether the 276 is suitable either but someone else will let you know about that, i'm not too hot on cams. (or anything other than breaking engines to be honest :) )

not sure on which T2's fit, R5GTT does as does the one from a silvia, just make sure they've got a 4 bolt fixing as you can get 3 bolt ones i think.

kk thanks does anyone know if i have to change my cam? and also i am running a 10 :1 compression ratio what do i need to get the compression down 2? and will this be obtainible by opening the chambers??

regards will

10:1 is way too high for turbo use, i think most people go down to about 8:1. not sure whether you'd be able to drop it that much with head work alone.

i'd personally consider flogging that engine as it is and using the money to fund a specifically built turbo lump. or picking up a standard metro 1275, rebuild it and put a decent head on and it'll run 10psi all day long.

Nick :)

would you be able to run it on 9:1??

still a bit high really for anything other than standard boost. metro ran 9.4:1 as stock, but only used 7psi boost.

i reckon at a push with a proper RR setup, a good intercooler you could run 10psi on 9:1
