[QUOTE="Cressidom, post: 423355, member: 3217"] 1JZ info on the net Hi Ree34, The 1JZ has a lot of potential, it's a great engine with some minor issues. Since you got the car/engine 2nd hand, you should check on the internet for 1JZ, there's tons and tons of info available online. By 'refurbish' I can only suggest the following, Firstly find a mechanic who's experienced on this type of motor. You'll find in your journey to refurbish a lot of characters who claim many a things on the 1JZ is either damaged or need to spend a lot of money My suggestions, start by find a 'sifu' for 1JZ Have him take the turbo's off and look for leaks. Engine oil will need replacement. Never mind if your seller or had 'just' changed the oil. Turbo cars very 'manja' about the oil clean oil - happy turbos. Dirty Oil > caking > sad turbos > empty wallet. The CT12A Turbos will only handle some abuse, they're ceramic. Some TLC should take care of them. 1 JZs have issues with ECU (some members here have had that problem), Fuel Regulator,Timing issues, Coil packs cracked etc. Again this info is available on the net. IF your's is a manual 'Syabas' the R157 is solid gearbox, my guess is usually a second-hand car with 1JZ already kau-kau used. SO The oil sump will need to come off to see any sediments = tell tail signs, best time to clean the oil pump etc. Other than that it's also some 'luck' involved. SO once you get the refurbishment done 1 by 1 = save money la..hopefully the engine will give you much pleasure. my dua-puluh sen comments. Enjoy Dom [/QUOTE]
