its a standard ca18det just refurnished the motor, aka rings bearings. with a t28 sort of lol garret turbo. with a microtech. ca project yer the tunnel is big but worth it, so much easier to get to the bellhousing bolts if and when u need to do a clutch. there is roughly 2 finger space between head and firewall, yes plenty of hours haha got over it for a long time, welded tunnel in both sides then used sealant both sides to keep rain out. im just a motor mechanic not too keen on body work lol so i got a guy doin it for me. he reckons a good 4 to 6 hours, as for the heater im just goin to use a hairdrier cause all u really need is lots of noise and hot or cold air comin out, for a blue slip, but can get a good blueslip done ;) without viewing. as for facebook i tried once addin pics on here it didnt work lol
