yeah. well, a well balanced motor would have pressures in the intake manifold that is somewhere near the pressure seen in the exhaust manifold. just because SCC did a test on the SRT4 and saw 35psi of back pressure in that manifold doesnt mean that is the norm. what you are talking about sounds...

yeah, ive got a pic of it, but its on my pc that crashed and someone needs to fix it! ive got apic of the end of it and you can see right thru it. its fully Tig'd too. it looks great.

sweet, i was always wondering about his quality of parts, i guess if you guys say hes kosher, ill shop with him.

well thats just a broad generalizatoin about the self adjusting of long-term/stored fuel maps for the open loop operation. i dynoed a 1JZ and a 7M, they BOTH went dead 10:1 AFR 1000rpm after spoolup, or peak torque rpm range. its a built in safety net from toyota. i had to tune both of these...

its hard to say, since the entire engine is of different dimensions. i think the overal length of the JZ's are slightly longer anyways. but i know the rear journal of the crank shaft sticks out past the bellhousing flange, this is how toyota was able to shorten the 1jz bellhousing, still have...

traffic is teh winn!!! and we need some more smilies, you can never have too many. too many MKIV owners have this attitude that "Oh, the MK3 isnt even a supra"... bitch please, it was a supra before your toilet was ever a ink spot on a note pad!

hey grimace... a SP61 would be a great turbo for a street car and you could easily make 400rwhp. you could most likely take down alot of 500rwhp dyno cars, just because it spools faster and wont be too violent that it roasts the tires. its a damn good street turbo. a T88 is primarily for top end...

lol, thanks hal, for that wealth of info. i totally got you on the bowl blending and back cutting the valve seats to allow a larger chamber for the exhaust gasses to purge into when the valve lifts off the seat. keeping the exhaust port diameter the same at the manifold entrance creates more of...

soo, i was in the FAQ and looked at Allans flow bench results for unported and ported 7M heads. stock lift is about 0.311". IIRC, the intake side flows 178cfm at that lift, and exhaust side flows 124cfm at that lift. the exhaust side is significantly imbalanced from the intake side. i...

you need to make sure that the actuator rod for the heater valve is COMPLETELY hidden inside the actuator. its lowered position is about 30* from verticle when at rest. when fully open, the heater valve lever is about 30* from verticle at the top of the travel. if its only resting somewhere...
