please tell us what size pump your looking for? just so others know,
Try the Walbro one. Is holding up well for my 6A13 conversion :)

next question what Boost do you run?
So between 6a12T
6a13 transplant
or
Evo transplant

What boost do you run?
What power are you putting out?

Okay... I'll put my name down for info
FTOSam: MIVEC Turbo / Non-Mivec Forged Turbo

As far as compression, i think it has a lot to do with the condition of the engine...

I ran 5psi for only about 3 months before my engine gave up (135,000kms)... Piston rings gave way due to compression (FACT)...

I'd say 5psi is okay for daily use on a good cond engine... but recommend a bit more boost (7psi or so) on a freshened up engine with a decomp gasket....

9PSI on a 6a12 your getting almost 320BHP?? 8O
Well impressed!

I wanna throw a question out too...

What is the best material (as in tubing, hose etc) to make an oil return line? And what are your reasons behind that?

This thread may well become the "go here and read before asking turbo questions" post :) I like it!

I was thinking about it last night and was actually thinking something like those metal brake lines would be best (bigger diameter of course) so that there is no chance of rupturing.

Discuss :)

Oh, and I think I posted before, but my 6A13 is stock with stock TD03's, VR4 fuel pump and VR4 computer, running 13 psi. Hit fuel cut at 13.7, backed it down to 13.6 but still got a little creep at top end in 3rd, so backed it down to the nearest whole number. 2 years at that pressure

For my 6a12T
I have a braided hose feed to the turbo (diamater not huge) which is fed from the oil pressure sensor.
The return is gravity fed,
And is made up of 12mm braided hose for best retun.

Well, so far 227kws (305hp) at 13psi with failing coil packs, failing waste gates & cam timing thats out.

Using braided lines for rear turbo, factory steel lines on the front.

8.5:1 CR...

Custom made Cams help... as does a brand new blueprinted, borred out, honed, and balanced engine... Good Microtech ECU and a big fuel pump, braided fuel lines etc... 350cc injectors are stopping me from taking it further..

As far as oil lines.... braided all the way... cant go wrong with a braided line (even my clutch line is braided...)

Boost: Im only running 5psi at the moment because i need to upgrade fuel pump and fuell pressure reg, which will be the same one as ben's.



Oil lines: Braided as well, from memory its round the 12mm ID mark, But it should match whatever the size of the hole is out of the bottom of the turbo. That goes for the oil feed line as well, from memory thats 4mm but will vary depending on the turbo. B/B turbo's dont need as much oil therefore have a restrictoron the inlet side.


I personally wouldnt do anything but braided.... We are talking about an oil line. If that splits it could mean all over red rover.

Next question,
WHAT ECU & WHY

What ECU are you useing and why?

Posted: Fri May 01, 2009 6:11 pm
by d_dan
Im using a Greddy Emanage blue
I feel its enough to control the setup I have,
It controles the timing, and the fueling there isnt much more you need?

Correct me if im wrong.

But when i do get forged internals im going to go for maybe a stand alone

I have the emanage ultimate, i think its a great cost effective piggy back for low boost applications. I wouldnt use it though, if i was going over, say 12-13psi maybe even a little lower.

Anything over that i would be seriously considering what benny is running. My tuner recommended that to me if i want to run pound, but hey is just trying to make a sale. lol

ECU's are the biggest reasearch i think you need here,
Because every tuner is going to offer something they sell and that they like using.

So you might loose out from time to time.
Where I live there are 3 main tuners.

1 says Autec the other says Motec and the 3rd say hell map anything.
Supprisingly enough :? the one who says autec isnt a motec dealer and vice versa!

Using Microtec LT-10s.

Why? Is a well known brand... has good value for money for a stand alone system.... Can handle boost levels for a mild system and for a crazy system...
