Are you rebuilding it to puch more than 600rwhp?

If not it will be cheaper just to buy another GE engine, they are cheap. I can get a GE motor for much less than the cost of used TT auto rear diff.

i want to push about 400- 450 hp... thats enough for me for now.. but even with another GE Engine lets say one from japan.. still would need a rebuild before boost wouldnt it?

how much can you get an engine for?

You can rebuild that with stock parts for your power goals. No need for anything aftermarket.

Piston sets, rings, seals and gaskets are a lot more affordable at the dealer than you think. If you are buying pistons you can go with the TT set as they will go right in.

What exactly is wrong with the engine you want to rebuild?

hmmm...191k miles... gonna turbo and kaboom..

also should i raise the compression on the engine? the FAQ says i should. so i should get an aftermarket head gasket or what?

you seem to know alot about turboing the 2jzge.. did you do somethign similar?

[dejacky]

Not necessarily. I would take it to an experienced Lexus service shop and have them perform a "Compression Test" on the engine and overall car diagnoses. There are people turboing high mileage 2JZ-GE's that have been maintained throught their life.

[SupaSupraSE]

yeah, I would too. You could find your parts as well from sellers on sites such as here, supraforums, etc.

Like they said you want to lower it. My motor is bone stock, compression and all. 140k miles and running beautifully. If your motor is taken care of you can boost it as-is with stock compression but that limits you powerwise.

[MadMaxx]

190k? Pft..just getting seasoned man ;)

Do a compression test, see where you stand. If you want to build the bottom end for some serious power, you're looking at about 1500 worth of parts to do it right (aftermarket). Of course, the GE bottom end will hold 600 all day long, so there's no point unless you see yourself going later down the road.

I've got 2 GE motors if you need one (1 lexus, 1 supra). Both have excellent compression, very clean. Don't replace your current unless she's not showing good compression though.

I wonder how long the days of cheap and plentiful GE motors will last :lol:

As Maxx said, do a comp test and a leakdown to see how the pistons, rings and valves are sealing. As long as the results are good I wouldn't bother tearing down the engine. You can also check the oil pressure (with a real gauge), that will give you a indication of how the bottom end bearings are.

thats sound like the plan i guess. just one thing.. what are the numbers for all those readings i should be looking for?

All those numbers are in the factory repair manual which I'd strongly recommend to anyone reading these forums.
