Turbo for 4AGZE
|

Hello again all,
Finally got my 4AGZE, but now
I know this has been covered before but not qiute in as much detail as would alow me to make the right decision (and without sounding like the opreah show) feel like i made the right decision.
Im going to use the factory computer and document the construction for the 'Articles' section, but i need some people in the know to answer the following.
* Your type of 4AGZE + internals?
* Turbo/Donor car?
* Boost pressure?
* Cost of turbo?
* Power Output?
Also the Approx boost threshold, Power delivery characteristics, revs at max boost.
Other things which dramatically affect output and 'spool up' of the turbo ie Exhaust and Cooler.
Sorry to be so specific, but i figure you fellas are the greatest 4AGTE experience bank.

I'm using a nissan rb20 roller bearing turbo, and today at dyno day I got 141RWKW on LPG from it. If you like I can scan and send you the graph. I think it works quite well personally, but I'm gonna change mine for an rb25 one very soon (cos I can really!) These turbos are supposed to be good for about 160 at the wheels, whereas the rb25 ones are claimed to around 180-190, and a tiny bit more from the VG30 ones. Otherwise, I'd say don't go past a new garret GT25/external wastegate. 4AGZE's are pretty tough little numbers, just be careful tuning it and it should crank out some fairly healthy numbers. Feel free to ask me anything you like about mine or others I've seen.

Thats the turbocharger i was leaning towards, the ECCS series 2 RB20 one. But being the stock computer I need to keep it within 14psi max boost pressure.
Given Toyota's tendency for conservative tuning, there really should be no reason to suspect the stock ECU will do a bad job. It'll just be more powerful that the SC12'd thing and allow usage of the last 3000 odd rpm without a flattening powerband.
The RB20 unit definately sounds like the way to go, others have had great success with it. Michael from the 'Articles' section has 161kw @ 12psi from F1MERC (but from what ive read an aspirated series 1 block).
By any chance, would you know how much one should expect to pay for an BallBearing RB20 unit?

mrshin u seen any normal 4age's turbo'd, do they handle the boost?
im talking like 6 psi
would the rb20 be a good turbo for that?

The rb20 turbo's are good but also check out the tdo5 and tdo6 items. The latter can support 400hp and they are fairly cheap. I would think a stock 4age would handle 6psi if tuned correctly and preferably was intercooled. If these 2 were done maybe even 8 psi would be possible and around 50% power increase.

* Your type of 4AGZE + internals?
Late AE92, Twin coil bigport with AFM. Stock ECU, stock internals
* Turbo/Donor car?
LAurel Rb20 jobbie. Same as R32 but no BB.
* Boost pressure?
8psi until i IC it.
* Cost of turbo?
$150
* Power Output?
More than a SC14 and IC equiped 4AGZE
*Also the Approx boost threshold, Power delivery characteristics, revs at max boost.
Starts at 2000rpm in 4th and 5th, hits max by 2700 or so, drives smooth and with little to no lag.
*Other things which dramatically affect output and 'spool up' of the turbo ie Exhaust and Cooler.
3" dump and front pipe, inot a 2.5" exhaust, no cooler

would those be the mitsibitchi cordia turbo's 
if so how would you best tell if the td06 was in good working order?
i am getting a t-25, but could get a td06 of a cordia instead if i wanted, (the guy with the cordia called it a tc06?)
i just thought if i got the t-25, i could flow it or something, later on when i could afford it. i've read about turning them into a t3 as well?

thats becasue a codia turbo is a TC06, if its a AA or an AB model
the later AC cordia got a smaller TC05 and an IC.
TD05 is a early WRX/VR4 turbo, although the flange sizes and shapes are very differnet between teh wrx and vr4 models.
TD06 is aftermarket jobbie. as in big ass model.
for a 4a-gze, a high flow T28, RB20 T3 or a Td04 would be perfect.
For a bit more lag its RB25 turbo of a TD05 wrx turbo.

AE86_Sprinter,
thank you for clearing that up for me. i'll stick with the t-25, and upgrade later (maybe at the same time i can afford a aftermarket computer)

Thanks muchly fellas you've been a great help.
How much output could one expect with an RB20 turbo pumping 10-12psi?

Does anyone know who can make me a Manifold for the mr2? If so where and estimate in price?
Also.. that guy with the 4agte in the mr2 at the dyno day.. Is he a member here? I would really like to get in contact with him..

not for a while...
considering i am now a fully qualified mechanical engineer, 15 hours of my time might add up to a bit  just kiddin.
seriously tho, its hard to do if i dont have the car, and the turbo. If you wanted me to mount it exactly where i did, that would be easy, but there is a heap of frigging around. I spose most of the fiddly stuff is done because i drew the flanges out on AutoCAD then had a mate laser cut them for me
My manifold may be for sale soon anyways
Cheers
Mike

hey, i've got AutoCad 2000 (i've been doing it at TAFE) what type of laser cutter did your friend use? what type of file did you save it under, for your friend to use?
sorry for all the questions.
thank's.

I just saved it as a .dwg file. Dont know what type of laser cutter, he just said give me the file in ACAD 14 format, and that was that.
That SDS page is good, apart from the collector, its attrocious.
http://board.performanceforums.com/forums/attachme nt.php?s=&postid=62554
thats an old photo. Number one runner is a bit long, and after fitting i noticed there was no reason to take suck a convoluted route to clear the crank angle sensor and the compressor cover. If i were to do it again, I would make the turbo high mount, althoug it is good having it all hidden away, just makes fitting stuff a bit harder.
Take it easy

 what a b@stard of a job, turning my ze into a te!!
had to replace soooo many thing's off the ge to be able to run a turbo on the ze. changing the induction setup (inlet manifold, feul rail,throttle body, i'm useing the ge throttle body it's bigger) was no drama, but i had to use the feul lines to the feul rail cause they were different too, having to put all the other crap on took a bit of time (no wonder the shop's charge so much to do it!) the alternator i knew had to go where the s/c was, so i could tension the belt for the water pump, but then i had to change the water outlet from the head (it has two holes in it for the top alternator bracket) the pipe that run's along the back of the engine had to be changed as well. the aircon (i'm keeping it cause i like it!) has to have the ge braket put on, to be able to tension the belt, then the ze a/c compressor is no good (pulley offset is wrong!) blah, blah, blah. at the moment i'm running a n/a ze,(it is gutless!!)  till i can get the turbo manifold made and turbo and exhaust done.

With mine, I didn't have THAT much trouble making everything happy with RWD. For the alternator, I got out the welder and grinder, and welded a little number together to shove the alternator where the blower once went. By measuring this up carefully, it meant that 2 belts the same size could be used, one for alternator/water pump, and one for A/C (which also drives PS should I add that). All original pulleys are used, and you've always got a spare tensioner/belt attached to the AC if you need one. (Actually, I didn't tighten mine up and lost it on the road somewhere... but thats an entirely different story!)
As for water pipes, I used the GZE thermostat housing upside down on the end of the water pump, it put the heater hoses in a nice place to get them to the heater/gas converter/turbo. Maybe not the tidiest conversion around, but hey, it works
Oh yeah, its incredible how much those lumps of cast iron that both the blower and AC pump mount onto weigh!
