biased99 we havnt done a 1uz but we have been starting to workout ideas for them. that said there has never been a motor that has left the shop that the customer hasnt been over the moon with. we fix alot of motors that have been rebuilt by some of the better known work shops for jap engines{ i wont name them but lets say 99% of them} had one two weeks ago that we had to rebuild that the customer had payed nearly $8000 for a 1.8l turbo motor that had cast pistons and 10-1 comp. the thing blew head gaskets every ten minutes. we cc every turbo motor to make sure comp ratio is exact. my best advice is to think of what you want from the engine and then how much you want to spend. here is a few suggestions, if you want more power turbo or supercharger would be the go, i would bring the comp ratio down to 8-1 for higher boost{12-25psi} or bring it down to 8.5-8.9 for mod boost{5-12psi}. if you want to stay natural id change valve springs to higher rate and put large valves in. then look at the flow of the heads and see if they can be increased much but knowing toyota there wouldnt be to much to gain from them. cams i would get for you would be from one of our suppliers that can give us the best they have gained from the 1z. then i would look at the intake system and see if its cost effective to change for the gain it will yeild. then we can make or have made extractors to suit the engine and finally pick an aftermarket computer that suits you. we will always give you the choice but will advise you on the best. it really all comes down to the money you want to spend. we never say its going to cost $2000 then in the end it costs $7000 as so many guys in this forum will tell you has happened to them. we will give you a figure to work on and it will be very close to that unless along the way you want to add to it! god i hate typing. mick email me if you want more info [Report message to a moderator]
