Title: Dammit!!!
Post by: zukgod1 on May 27, 2008, 09:09:35 am: Well my Saturday started out good but ended badly.

I emptied over 4 qts of oil out of the intercooler.

Engine started to race away just as I rounded the corner to my house, had it in 3rd (luckily) so I was able to drop the clutch and kill it before it toasted everything.

Post by: zukgod1 on May 27, 2008, 09:11:29 am: Guess I need something a tad more robust than a k24..

Is the T3 any better?
How about a k26?

Maybe I can use the smaller exhaust housing off a k24 and use the compressor and cartridge from the k26?

Post by: zukgod1 on May 27, 2008, 10:14:32 am: Look at those fins there..

The shaft is broken.. Need a stronger turbo.

The "corner" I was going around as the engine started to race was just a regular corner you would go around in a city.

This happened about a mile from home, started to ingest oil as I got home.

Ummm ya high boost and fast shifts is what killed it.

The sound of turbo bark during shifts told me I was running the boost a tad high. Like 30spi. Hit 40 a few times pre intercooler.

Was really working that suka. I would love a VNT but I'm not to sure I want to go through the control part to get it to work.

At the moment I'm leaning towards building a K24/26 hybrid or using a T3.
If nothing else the T3 should be beefy.

What are you running for fuel?

Pump
Injectors

I think the biggest thing is I'm running a 10mm pump with a 1.9idi camplate in it.
Merc nozzles as well.

Post by: Justin on May 28, 2008, 04:54:01 am: get me some of your specs and I might be able to hook you up with a new borg warner turbo charger. what kind of power you want to run, along with Nozzles, boost pressures, displacement and all that fun stuff.

This could be fun,

I want to be as close to 150hp as I can get without loosing reliability. I would love 200 but I would like to keep the head under the hood.
Running a 1.6 ltr (1mm over), using Merc injectors @ 155bar and I have some Case injectors as well, those suka's flow some fuel for sure but I haven't been running them as it's hard to get a good idle.
I'm running a huge FMIC bar and plate style.

I would like to have it around 10psi @ 3000 RPM. Right now @ 3000 I'm running about 4-5 psi (freeway cruising) and about 750-800 on the EGT's I suspect that's largly due to the ACN trans, it's geared taller for freeway.

The only porting is gasket matching :(

What other info can I provide?
