Yoda's Turbo Log

[Yoda]

So yea this will be the thread i will keep in regards to everything turbo relative to my car.
As an update still waiting on my return the person that does it for me made a mistake and had to redo it.

In preparation for my turbo i am doing more research. What gauges do you guys
think is NEEDED to accurately monitor my engine?

Here is what i have so far on my list that i am picking up next week:
Turbo timer
Boost gauge
EGT***
Oil Pressure

*** heard its more accurate than A/F gauge cause leaded gas fouls them over time ***

Anyway form your experience guys help me out here lol

[Abodame99]

should get egt for each cylinder, that would be cool

[cali yaris]

Air/fuel is far more critical than EGT (they are completely different)
water temp
IF the turbo is water cooled (and it should be) you won't need a turbo timer.

ditto this: Air/fuel is far more critical than EGT


air/fuel is the #1.

egt -was- probed before a/f sensors were perfected.

[Yoda]

ok kool. i guess my info on the egt was a bit outdated.
what brand do you recommend thats not just there for looks. i could care less if its all flashly lights and makes sound. need something accurate

Thanks in advance for the help

EGT is good instrumentation but not very helpful unless it's being data logged against the other 3 cylinders. EGT can tell you a few different thingsn but AFR is the number one reading for tuning and combustion efficiency. If you are able to instrument all four cylinders for EGT, then you might be able to tweak your tuning to gain some more or less depending on the risk you are looking to take. Then, of course, tuning on a dyno and tuning for what's on the real road is a whole other story. I'd say most important are as follows, in order:

1. AFR
2. Oil Pressure
3. Boost

Sad news.... My tax return was not as sexy as it was before(they took off $1.5k the tax guy confused mine with some1 else).... So the Zage kit is whats on the menu lol. Did my research on the kit and spoke to some other forum people( subaru,swift,honda) They all say its a good starting point. The main short coming is the turbo. It is oil cooled not water and is not ball-bearing I can live with that. Most report that after a year or so the turbo starts to fail and they replace it. On rare occasions some even reported boost creeps but thats when they had a turbo back exhaust.

I will be ordering the kit next week hopefully Installation seems fairly easy

I am really happy it comes with an oil pan.

So to add to the list for this kit i will need:
injectors
spark plugs - maybe
BOV looks - very inferior
New turbo - some time later
e-manage - pretty cheap on ebay
Anthing else, questions, concerns, let me kno. I am getting boosted next month thats one thing for sure.

Heres the Zage parts list

If you're comfortable with that track record, then you are good to go.

6psi internal wastegate?

And make real sure it's not a downpipe for an xB, because that will hit your subframe.

They say the down pipe fits. As for the wastegate have not asked about that yet. Hopefully Ancla will give me a good deal on their kit now that i let them know that there is competition and sponsor me to some extent

Who is going to wire and tune the eManage?

i have a tuner best in all of central florida. cft ftw

[Yoda]

Looking to pick up the emanage now. From looking around some i found this

http://cgi.ebay.com/ebaymotors/Gredd...a#ht_500wt_956

what ya think?

[cali yaris]

It's an eManage, yup :D

Yoda: I would like to advise on some issues with the Zage kit:

1) The oil pan it comes with has the return bung in a very awkward position. It is positioned towards the front of the car. What happens here is that when your oil return line comes out from the turbo its route is straight down, which is what you want, but then you have to route it foward almost parallel to the ground, which is not good. A proper return line route should as strait as possible. I know this cause I have there pan on my car.

2) The AFM is mounted to the inlet of the turbo, which means is sucks through the AFM. I feel its better to blow through the AFM, just my opinion.

3) The routing of the I/C pipes is under the car. If your car is lowered you are going to have clearance issues.

Issues 2 & 3 are small, but issue 1 is a big deal. Im not trying to have you not buy their kit, Im just trying to make you aware & help you out.

[Yoda]

no prob thx for the advice. 2&3 i knew about. we are here to help each other so thanks for the info. my question is what adverse effects can take place from the oil return being like that? shorter life of the turbo? if its a detrimental problem then i will just tap my own where i want it. if some of you who have turbos can show me where your tap and lines are that would be helpful.

at work so i am typing this up on my phone. sorry for any grammatical errors

[cali yaris]

I tapped mine into the lower part of the block (that serves as the top of the "pan"). Our pan is so shallow!

Im going to redo mine the same way. I just took a chance with the Zage oil pan to see if it works.

The problem is the following, the oil feed is high pressure in, the return is low pressure gravity feed. What is happening since the return is low in the pan it uses the suction of the oil pump to flow oil. When you are accelarating there is no problem, high pressure in, suction through the oil pan. But at low speeds or between shifts there is not enough suction/flow out of the turbo so you get oil creaping through the seals in the turbo. At that give a little puff of smoke through the exhaust. The best way is up high in the top part of the pan. That way the oil will just flow out of the turbo & into the top of the pan above the oil in the pan.
