the conversion allows you to use your current clutch and cable and stuff on the hydro tranny.

think of it as the conversion is converting the hydro tranny to a cable tranny.

you can swap it to hydro like hailchristian said

Pretty sure it's 2 steps of torquing, and it goes 20 ft-lbs, then 61 ft-lbs. You cannot reuse OEM head studs, you have to buy new ones. You'll also need a new head gasket.
There is an order to torquing them down. You start with the center 2, and then go outwards, alternating sides and criscrossing.
It should go something like this:
10-6-1-3-7
8-4-2-5-9

first torque them all to 20 ft-lbs, in order, then come back around and do them all again in the same order but this time to 61 ft-lbs.

They're 215/40R/16's. I like your EF man, ****'s hot. Sorry it took me so long to get back to you.

sorry it took awhile to get back... but yeah your single is just fine dude. you can turbo yours with like 10 lbs and itll beat any dual out there... if you really want a dual you can import a whole front clip from japan for about 2500. the motor will have about 55000 on it which isnt bad and youll get a right hand drive front clip lol. thats what did anyway.
