My knowledge isnt super on the TE44 turbo, but I'm sure DaveH chose a decent enough turbo....
On stock compression (10:1) at around 10-12psi you should be able to make at least 400whp...

You wont need to touch ANYTHING. I'd honestly upgrade the injectors and fuel pump.... though the injectors dont HAVE to be upgraded (i've seen enough dyno results to show me that 400whp is doable with good gas on the stockers)... but I'd still upgrade them, the cost isnt that bad and its easy to find a set of 440s or 550s that can be tuned with a LS400 MAF and S-AFC

the bottom end will handle 400whp just fine... the rods and crank are the same as the GTE engine... the pistons arent all that different other than not being heat treated...

I dont know why you couldnt find any search info... this has all been discussed before Most of the old turbo guys don't post on here much. I used to be one, but I sold the kit a while back and I'm going 1jz-gte now

CmpterWiz (spelling?) may he rest in peace, had plenty of documention on his installation of an old Toyomoto kit (i dunno if they make those things anymore, such a waste of money for what you got)... but it was GREAT info and he also documented his tuning process

the thread's name was "Could it be Turbo" just search for that and its an OLD thread so you'll have to search...
Also at the bottom of my sig, I've got a link to my procedure in building my own.... plenty of info there too

I already have most of the na-t parst I mentioned earlier including the turbo. My concern is that several persons have told me about blowing their 2JZ-GE's on stock compression at only 10psi..how are people boosting 10-12psi on stock 10:1 compression and not detonating and not going stand alone ECU?

Bean

they retard the ignition a bit? around 3-4 degrees?

I've not heard of people blowing up GE motors with just normal boosting conditions.... at all...
if someone blows a GE motor, it was either already on its last leg or someone did something completely stupid that caused it... (like a time they ran 20psi by accident on 93 octane, but failed to inform you of their stupidity )

I dont see what the big issue is with 10-12psi needing a standalone? if you were wanting to run 15-16psi on pump gas yeah i can see needing a standalone to fine tune it (the ignition curve especially).
I ran 10-12psi all day long and never had any detonation problems EVER... not even ONCE...
I've got ~150k miles on my car and it runs just fine even without the turbokit

I mean, seriously... you've got a bottom-end that so far has withstood over 700whp with no problem; and i'd bet even 800-900whp (talking GE bottom-end here) and you're thinking you're going to blow it up? You wont detonate at 10-12psi if you retard your ignition some (its really that 4500-5000rpm spike you have to worry about, if it werent for that you wouldnt need to run any retard)

Can't I just "fiddle" with the distributor to lower the timing accordingly to make it "safe" @ 10psi too?

Bean

iTrader: (1)

sure, thats how i did it...
was going to use a Apexi' ITC but there were no instructions out on how to get it to work with the GE motor... so i sold it

dejacky

<-- this is where I am now. Some persons tell me 10-12psi is safe if you pull back the timing, then others tell me it's much riskier and bound to blow a 2JZ-GE at those 10-12psi levels with 92 octane pump gas... I

Who is telling you this? I'm not going to claim to be some super guru, but I know PLENTY of people that went 10-12psi on stock compression with retarded stock ignition and had no problems of blowing their 2jz-ge

I mean seriously... its only 10:1 compression, and the GE block can handle 1000hp just fine, whats to blow up if you're not detonating?

MBC VS. Wastegate Spring VS. HKS EVC EBC

I originally decided to go with a manual boost controller to save $, but then heard that MBC's are prone to boost spiking whereas EBC's are safer, can control and prevent these boost spikes. Help?

SC3002JZ-T

I'm running 10-11 psi all day long on stock motor with no problems..I'm sure it could take more just don't wanna find out...just make sure you have plenty of fuel...pump ,injectors,fpr,etc

i ran a greddy profec b2... and would recommend it to everyone... its a great controller, its easy to use and install...
has plenty of features, is small and concealable or has nice light effects and can be positioned to be visible...

its got tons of other good reviews too; better than the HKS and Blitz units too from what i've read

so bean:

with stock compression and 10-12 psi with few degress retard, can you use 91 octane gas or shud it be higher?

dejacky

iTrader: (2)

SC3002JZ-T,
when you say the following:
How many degrees are you retarding timing and do you use the same distributor method as Bean?

indypwr

he prolly retarded timing about 2-3 degress........that's is more than enough ....
i am more worried about the gas if i can use 91 octane...

dejacky

iTrader: (2)

I plan to use 93 octane, but I heard if you use "premium" gas you should be okay regardless of octane level. I'm ASSUMING your car might run a little worse with 91 octane, BUT if you tune it for that ocane fuel, you should be okay from what everyone tells me. Please correct me if I'm wrong folks .
