    Getting hot

    Is your radiator plumbed correctly ?? The INLET with the thermostat connects to the BOTTOM of the radiator. Is the thermostat the correct bypass one ? If the thermostat (when the engine warms up) is not shutting off the bypass, most of the coolant is rerturning through the block and NOT...

    2uzfe broken exhaust valves scenario

    How much valve/ piston and Inlet/Exhaust valve clearance do you have at TDC overlap ??????? How much lift does the cam have at TDC overlap ????? Too much heat melts valve heads - mechanical contact with pistons breaks valve stems.

    Machining Cams from scratch

    If you do not have an understanding of materials and camshaft design - go to a major after market cam manufacturer ! as a guide though 4340 crmo rough machine harden and temper finish machine/grind nitride straighten and polish have a very heavy wallet, it will be a lot lighter afterwards Erol

    1UZ into Mkiv Supra

    The 1990 Celsior (LS400) standard cruise control has a speed limit of around 105 KPH, which is about 65 MPH. It hits the rev limiter at that speed regardless of what gear you are in. Somewhere on this site, or the 'net, there are details to disable the cruise limit. If it is a Japanese...

    Thinner headgasket = more power?

    It would be worthwhile to read the 1UZ workshop manual. Lexus cylinder head bolts can be reused If the shank dia is above a minimum figure. I forget what that figure is but I know that I have never seen a std 1UZ that was below minimum.

    Head work and cams for N/A setup...where to get??

    John, Thanks for the plug but I am now retired and loving it. I would suggest Kevin Band at Kelford Cams NZ. He is one of the very few that really does know about air flow and camshafts/valves etc. Email address has changed Will send a PM Regards to all Erol

    Is 300 whp n/a 1uzfe possible?

    As I am well and truly retired I do not want to buy into this argument but - The 1UZ I built was bolted to a Superflow ENGINE dyno and delivered 538 BHP. If you want to compare engines then I suggest you take your engine out and bolt it to an ENGINE dyno. Then we can compare figures and not...

    help with what size throttle bodies to use

    What manifold are you using ? If the Tb's are on the std lower manifold then that is a large restriction.

    help with what size throttle bodies to use

    What makes you think it is "not doing the job" ? 8 - 40mm Tb's will supply over 500bhp With std valve sizes you will not get anywhere near this figure. I used 50mm slide throttles on Bob Muir's race engine, it gave 534bhp at 8800 and 338lb/ft at 7800. As the engine was never meant to run...
