where to buy a new engine?

[senna]

@Robokill: I have been nice to the engine. Never pushed hard while it was cold. I realy have no clue why it happened. But the people from the garage said the "oil distributing pumps" were worn out. Do you have an interrest in this engine? I'm sure that if you can help me with my new engine we can work something out
you think a 4agze would be the engine to get?
(and where can i find DMB engineering?)

[NoHachi]

Its DBM engineering. Just google on that. they're in maarssum I think

[alimonos]

can anybody write here what parts needed ( and how much for them) to make a 4AGE become 4AGTE?

Turbo is knowledge intensive...not money intensive. If you don't know what parts are needed, then you probably shouldn't be thinking about a turbo project just yet.
First read around and learn about them. http://www.howstuffworks.com is a great place to start and there are many more on the net. Once u understand how a turbo + auciliary systems work, then you'll know exactly what you need and where you can get the parts cheaply.

The 4A-GTE is not a factory engine like the GZE.

Thanks Ivan !
I was just thinking if someone who already did the conversion could writedown the parts and works needed ...

Thats no problem alimonos. Just realise that the chance of enginefailure is very big when you don't know what you're tinkering with. Basically turbo's are made up from the following parts:
Airflow construction, fueling solution, ignition solution, engine modifications.
These factors can be combined in various ways and for different $$. The most basic setup is:
Airflow: turbo manifold(log-type), cheap junkyard turbo (eg.saab), piping from compressor outlet to throttlebody.
Fueling solution: std computer inc rising rate fuel pressure unit.
Timing solution: back off the base timing a little bit.
Engine stuff: none
That should get you a safe 4-6psi anyday. Depends a little bit on the condition off the engine etc. That would equal about 4/14.6=27% to 6/14.6=41% extra power.
Once you have that basic setup you can start and improve it in steps. The first logical step is the addition of an intercooler in the inlet stream. The cooler charge will allow you to run 6psi safely with a bit more timing (big improvement in bottom end power). You could maybe squeeze out 7 or so psi with conservative timing (less ideal overall power, but more on top).
After that its time to get creative with the rest of the factors, but that tends to get complicated and expensive quite soon.

I believe 0sm0s1s on this forum has a 4A-GTE

NoHachi, could you please explain in details these estimations ?

[alimonos]

so if i understood well i can use the standard ecu and add fuel presure regulator to increase fuel pressure or a bigger fuel pump(which one?)?
As far as timing is concerned when you say back off the base timing you r talking about the timing advance (drop it from 10degrees to how much?)or it has to do something with the cams?
Thanks Nohachi!

@Jamie: Airflow is ~ relative to pressure differential. normal outside pressure =~1bar = 1x14.7=14.7PSI. Running 4 psi = 4/14.7= 0.27 bar boost is the same as having an outside pressure of 1+0.27=1.27 bar. Just multiply that with the base power and you have a quick and dirty estimate of the power increase. In reality it will be a bit lower due to the lower density of the hot intakecharge.
@Alimonos: I'm not 100% sure, but it should be that simle. A couple of caveats: I dont know what the stock ecu does when it sees boost..it could start causing problems. You'd then need a piggyback from the start.All stuff that you'd want to find out in advance. PLEASE DON"T FOLLOW THE ABOVE LIST BLINDLY!!!
