yeah, it aint a 2tg! it has to have more power there! 1812cc 88260 head, fully rebuilt (polished ports, lapped valves) 10.05:1 compresion twin dellorto 40mm sidedraughts ramflo foam filters (32mm chokes, 150 mains, 24o air correctors, 35 pump jets, 60 idles) 288 degree cams 34/74 overlap bosch GT40 coil, ignition is at 12 degrees, NGK BP6ES plugs genie 4-1 extractors 2 1/2 inch to first muffler than 2 inch ACL 3t pistons and rings (86mm bore, 1mm oversize) brand new new bearings, crank was ground all in a 960kg T-18 + me 65kg EVERYTHING has been stripped and if slightly damaged, replaced! everty single part was in prime condition when we built it so i dont think its any components letting me down. i've put through a couple tanks of optimax, not a big difference we are alright to tune the carbs, been silver soldaring/drilling jets here and there last couple of weeks, according to exhuast gas anyliser its made a big difference but not much change in performance, have been having trouble with one bit inparticular, when i punch it it gets VERY rich but i think we fixed that today...by bringing down the mains from 170 to 150 i've tried so many things, no noticeable differcnes anywhere, quite sure its not iginition, i was running 3tc coil but changed to the gt40, didnt make any difference...still running the 3t-c points distributor though could it be the engine timing? it's the only thing i havent experimented with since ive had the engine running. only problems we've had is some chronic running on, and cylinder 1 wasnt fireing but gapping plugs again seemed to fixed that linkages work fine, im definately getting full throttle when my foot plants maybe im expecting more out of it than it has, but this engine should spank the pants off what the 3tc had, it pulls really well at around 3500rpm, so it should have twice the balls it has there up high, especially with those cams! shouldnt it? i had a go along side of a modern stock camry, couldnt get in front! shifting around 5 grand. maybe i should take it up to 7000rpm and see what happens, but at about 5 grand it sounds like im forcing it and it doesnt wanna rev any harder! hence me not wanting to take it on a dyno or a drag strip yet! this pic is the engine at the moment, only difference since i took the pic is i took out the resistor on the ignition to bring it up to 12v, that didnt make a differnce either.
