Hi all

Anyone familar with the T04E 57trims being advertised in FastFours, toofast2furious? what are they like for boost? and are they spool friendly?

As i'm looking to upgrade my turbo on my RB20DET

For the price that they are at for 850bucks. im kinda thinking it might be better for me to buy one instead of a RB25 turbo (series1) thats 2nd hand.. and could fail with too much boost etc.

i'm looking to run about 1bar (14.7psi) a boost at the most .. maybe a bit more on scramble mode ..say about 16 or 18psi.

going on the compressor maps vs. airflow of a Rb20 .. it should be pretty well matched.. with a little bit of lag b4 boost comes in. not worried too much about the lag ..as the cars auto and is a little laggy on throttle response.

I'm upgrading fuel pump and dump pipe shortly, along with installing Jaycar boost and injector controllers. And i also have GTR injector to go in if need be.. but im not targetting much over 180rwkw.

Basically.. i just wanna know what ppl know about these turbos.... i know the say " u get what u pay for" .. but at the same time i'm not looking to see dramatic numbers .... just a useable turbo for a daily driver.

Thanks

Matt

i see , not good at all m8

... i was looking to buy the same turbo direct from the states.. but id imagine they the same.

as i know that they aint ball bearing type ..although he does advertise otherwise.

i was looking to probably buy one via this website

- http://www.turbocalculator.com/sale-garrett.php

but was looking at getting one with a 0.48 trim. and a 60trim instead.

as the toofast2furious was local. . i was thinking it would be faster to recieve etc.. less bs with shipping.

Those things are a wally turbo . Garrett NEVER offered anything like that in the TA34 range . T3/T04E is a generic Wollynetics term only .

Garretts TA34's used T04E compressor wheels up to about 46-50 trim . They knew that the turbines could not adequatly drive larger trim compressors . There was also a wide range of turbo's in the TB31 series that used these turbines with garden variety T3 compressor wheels .

If you buy one of those things you will go faster , but only due to the wallets weight loss factor ...............

    • I don't understand how this hasn't boiled down to - Upgrade the turbo when you have everything required. ECU, injectors, fuel pump, turbo, etc. Do it all at once.  If you don't have everything required, just enjoy the car as it is and keep saving up your pennies. 
    • Sounds like you've got an interesting adventure ahead here with local support if you have trouble! My guess is that, unboosted, you will be OK with a small upgrade like -9. What will happen is that once the stock ECU sees more airflow than it expects it will add a heap of fuel and pull a heap of timing to be safe because it can't understand how it could get that much air without there being an issue. You will see clouds of black smoke and it won't pull hard through the midrange and top end. So, overall it will be a bit frustrating but should be OK. If you are still nervous set the base timing back 2o through the CAS, but it will be even more sluggish everywhere. As said above through...this is not my guarantee your engine won't be blown into a million pieces, leaving you looking for very hard to find parts A better idea is get a computer with logging ASAP, wire in a wide band O2 sensor and a use remote tuner. I've done multiple cars this way and while it is not as good as a specific tune on a dyno they can get it 90% right. I'd suggest if you can afford an R33 GTR these days you can afford an ECU and tune. And if you can't afford that you sure won't be able to afford the rebuild if it goes bad in the meantime,.  
    • Yeah it would be nice if someone took the time to put that sort of information together, but there are a lot of variations in looms. I think you are making this way hard for yourself if you just want to get it running....sourcing an SR20 with the right wiring will be a billion times easier than matching the RB loom to an S15 chassis. If you do end up going this way, you just need to trace every wire in the loom with a multimeter, 95% of them will go to a location you can confirm at the ECU.....and then post it up for the next person who needs it  
    • Just top it up with water, and keep a general idea of how much you added. It is normal for water to be pushed into and pulled out of the reservoir through the cap, and it should not be more than half full or it will be likely to overflow when hot. Any decent mechanic can do a pressure test of the cooling system to confirm if you have a leak. Keep in mind if it is only leaking a little and when hot it may well evaporate before you see it hit the ground
    • I'd ask the shop what they used and use that. Mixing coolants is sometimes OK, sometimes not, and you have know the details of each coolant to know whether it's a good idea or not.
