Hey piston rings have gone in my 1uzfe so have to pull pistons out so would be ideal time to do something like increase the engine capacity a bit with a rebore. Has anyone done it before? If so, how much extra volume did you get. Cheers

Quote..Why the new cam belt? The one that's one there now has only been on there for about 1000ks..

Hey guys planned upgrades for this motor are simply to do the headers and maybe port/polish the heads. Theres a guy doing real good jobs quite cheap for around $750, but its the cambelt on/off and dissembling head thats kind of putting me off. Anyone else had it done and had a good gain from it...

I wouldnt say screwed, just got to make the sump bigger and that should fix the problem

Hey thanks for your replys, Ive had the car at another mechanics today, and he says its not the oil rings, its the sump(apparently also the cause of death for the last motor). I bought the car with a custom sump fitted to it, but it seems they have made it to small, as it only takes 3 and a half...

oh sorry and its valvoline 10w 40

yeah i bought it from auto parts nz, and it came with a 3 month "parts only" warranty, but he is refusing to honour it because the car has a custom sump so is not being used by manufacturers specifications. And even if he did honour it, he would just replace the motor, but i dont want to go...

this is an import motor and only been in the car for a month.. and buying it was the cheap part. Getting it put in and the cambelt done and getting it tuned and doing some seals that went hard from it sitting so long, has now cost me around 6k so far, just for a straight swap as there was a 1uz...

Hey car is now burning oil under acceleration so think its piston rings not valve stems. Dam. Anyone have an idea of how big a job it is to fix on one of theses motors and how much it will roughly cost. Cheers.

Hey has anyone out there used lextreme cams? if so how do they stack up performance/quality wise? as they are quite alot cheaper than the ones ive been quoted from kelford cams. Cheers

Breathing system?

yeah i thought that aswell but ive had valve stem problems on other cars before and it keeps happening when your idling and taking off even when car is hot, this car isnt smoking at all once it warms up but is pouring out when cold

Hey after my car has been sitting for a long period of time and i start it, eg in the morning or to go home after work, it starts burning a thick blue cloud of smoke for about 5mins until its warmed up a bit, and then is completely gone with no trace of oil being burnt. Any idea of whats going...

Nah, looks bout the same as the factory one, just a different shape. Yea I thought it would need at least five ltrs so is quite a worry

Hey got a wierd problem, bought a 1uz with a custom sump that has been going for a few years, did an oil change today and oil level sits at full with only 3.7ltres of oil. Dont sound right to me? Does anyone know if the engine can run on this amount of oil because if I put anymore in it will be...

thanks for the response so far, keeping in mind what the end cost could rack up to be, and that the car cost me 9g to buy, does the 1uz turbo upgrade seem like a worth while option (to those who have done one)? Or am I better to sell it, put the money from that and the xtra 10g I was going to...

yeah have seen that but the manifolds are made for a high mount turbo which would be out of my bonnet trying to keep it as a sleeper

Hey there Ive got an 86 celica supra running a 1uz, am wanting to get some more power out of it so am going turbo. Single turbo because of engine bay restrictions. Have had an estimate made up by a good tuning shop here in christchurch, and they say if I want to drive in drive out with full...
