1jz build up help

[AZN MK3]

ok... now that i have my engine... right, i want to know if you guys changed anything on the 1jz engine meaning seals, to plugs and waterpump???? and what else should i look forward into changing before i actually drop it in my car??? also how much psi's is the stock 1jz pushing out of the twin's???

If your engine is out of the car, go ahead and get yourself a gasket set and replace all the important seals and gaskets while they are easy to get to.

It would be a shame if your RMS started leaking shortly after dropping the engine in.

stock boost is around 9-10psi or so.

timing belt, waterpump, anything else thats a bitch to get to when the motor is in the car

Thermostat might be a good idea. Maybe a water pump if it has sat for a long time.

thanks.... ummmm do you guys know where's a good site or place to buy the gasket set... or do you guys know if driftmotions have the gasket set too....

Champion Toyota (on SF) sells a gasek set.

I neglected to change my rear main seal, now it's leaking

Oh, it's a lot easier to change the turbos with the motor out, so I suggest throwing a single on it before you put the motor in

why is that???? doesnt the twins push enough as it is stock??? well im i was just lookin to do a stock 1jz set up... unless you guys think other wise..

stock twins blow.. at stock boost, at 25psi, daily driving, or racing. Poor design.

 

[SupraStardom]

Driftmotion sells thermostats for like 22 bucks. They sell the front and rear main seals too. They have timing belts, but you can go to a auto parts store and get one. I think it was something like a 88 izuzu trooper 4.6l (I think don't quote me, search the forum).

 

[annoyingrob]

Timing belt is the same a a 2.6L I4 Isuzu trooper, around 1986 IIRC.


I just suggested you swap out the twins because they will blow eventually, so you might as well upgrade now Seriously though, you can run the stock twins if you want.

ok... thanks man... ummm the one main biggest concern that i have is should i get an overhaul engine gasket kit or just change out the rear and main seal??? or if you can tell me what like the biggest defect i should worry about...

really just the seal's need changing,front seal,rear main,and possably cam seal's.all the rest of the gasket's in the motor are metal type shim gasket's that don't fail easy.you might want some new valve cover gasket's too.
