3tgte mods, tune up, problems

[adamke35]

gday lads, picking up a 3tgte in a few weeks, and ive been researching forums high and low. as far as i know without having the 3t infront of me, is it has standard computer, injectors, turbo. it has a 2.5" dump pipe and exhaust off a ct20 with small front mount cooler and bov. prior to dropping the motor into my car, its a ke35 with modded mounts, is there anything i should do or look out for, or drop it in and go from there?. i want to change plugs, oil, filter, any gasket that looks like its seeping, before it goes in, then i guess drop it in and run a compression test. i know the exhaust manifolds can crack, so ill mag particle test it at work.

mainly with this post what I'm aiming for is a good starting project to get the car boogeying. ive got no drama dropping the motor in, but don't wanna pull it out in a week to find everythings f@$ked, but i guess its hard without it running to start with. are there any points/parts to look for with problems, onces its in is it worth converting to coilpacks and aftermarket computer and if so what is a suitable option? i know its old tech and there are some tricks here and there. i will be abusing the f@$k out of this forum once i get my hands on the motor, but lookng for a heads up. cheers and let me know what ever u know

There's a thread on here that has more information on the 3TGTE than i thought was possible... That said, the issues that I've encountered personally are;

Gummed/munted injectors - All three of the engines i've had and gotten running had issues with the injectors. Might just be my bad luck, but worth checking.

Fuel Rail cracks - again a regular problem i've encountered is a small fracture that comes up at the front of the fuel rail. it's always in the same place and is a pain in the rear. I've now got 4 fuel rails that are going on the scrap pile due to this issue.

ECU - Not sure if anyone else has encountered this... I've found two ECUs that have burnt out a section of the fuel supply circuit.

The one thing you don't want to do is run this motor lean... It simply will not forgive you. if you can get your hands on a 5MGE AFM, then do it... will give you a bit of room for more boost, as it gets the computer to pump in a bit more fuel. We've seen 165hp at the wheels on a stock engine with 11psi and 5MGE afm, through a 2.5in crush bent exhaust.

Oh, and if you can, compression test before dropping it in...
