Just starting the major work for the EFI + Garrett conversion. Check it out:

Starting on the fuel rail and new injectors in place. They are Bosch 480cc units.


Mock up of the new manifold and turbo compared to the old one above. The KKK has completely seized and can only be spun with a ratchet attached.

I just read the Cars and Parts Wanted/For Sale forum and thought, "What the..?"

Now it all makes sense.

I wouldn't be surprised if your old turbo is coked up in the exhaust section...

Looking nice. How much HP do you plan to make? I ask because I did a little logging on mine this weekend and found I am seeing 80%+ duty cycle already at 6200rpm and 44lb injectors. I can't be pushing more than 180HP. Rack it up to supercharger inefficiancy? Maybe more HP than I think? Seems odd to me.

Is that 1 inch square tubing for the fuel rail!? Monster!

I can't believe Khal hasn't slammed it yet.



Personally I think it looks like a great beginning. Which Garrett are you using ? and did you make the fuel rail yourself ? (could you tell me the pitch between the injectors so I don't have to measure mine.)

Be nice, it doesn't look anything like that monstrosity. To me, it looks like he's building a log manifold in fact. Judging from the direction of those weld el's. That right macbdog?

Looks awesome.

Min I wasn't slagging the work, I was just poking fun of khal.I'm allowed to,he still owes me a Coke.

MacBdog is making exactly what I (eventually) plan on making.A log style manifold with a Garrett spinner.This has to be the easiest way to fabricate a reliable,long lasting manifold.Keep the pics comin' McB

I wish you guys were near me. I would love to help working on these projects. I stuck with a US car guy building a 33 Plymouth 4 door rocket, a coffin car ala the Munsters and a 29 Ford pickup. With the coffin car we made the NY Daily News, were on ABC and CBS during Halloween. I will try to get the coffin car on this site.

Yup thats right, I'm making a log manifold for a Garrett GT2871R with a .60 trim. I mucked around with a few other manifold configurations but there just isnt the space for someone with basic fabrication skills. After inspecting the inside of the stock manifold, I reckon the large steam pipe elbows will flow pretty good. The curves are smooth and the bore is plenty large. Pulses from the #4 runner should keep everything moving in the right direction. The #1 runner is pitched 45 degrees clockwise to position the turbo in the same spot as the KKK.

Yes the fuel rail is 1 inch square tube, I wanted to give myself plenty of room when welding the injector bungs. The bungs are made from 13.6mm ID steel tube so it should squash the orings enough not to leak.

Kenodog, the injector pitch was somewhere around 93.5mm. 1&2 measured 93 and 2&3 measured 94. There is play in both the stock injectors and the new inserts so it should be fine. I am planning on using the intake manifold bolts and rocker cover studs as mounting points to hold the rail down.

My target is 200HP at the treads.

924RACR: you are right. There is also enough play in the shaft that the compressor wheel has been turned to aluminium dust - when I take it apart fully I will show pics. Thank god my intercooler acted as a filter and caught all the shards.

MacBog, GT2860R is way more capable than 200@ the wheels In fact, couple of days ago we installed this turbo to the Audi A4 1.8T quattro and with standalone it made something like 270-280 flywheel hp WG spring set to minimum pressure (.7-.8 bars or so).
Good luck with the project!

Ugh, I have Garrett GT envy. Some 911 folks have reported that you can hear the turbo spinning down for almost a minute even after shutting the ignition off. Cool

Slightly OT - has anyone made a ball bearing cartidge for KKK? Or is Garrett's really that special?

It's not just the BB cartridge that's cool but also the 360 degree oil seal that keeps it from leaking over time.

This post has me stoked again about doing my manifold.Hey McB when you get it finished can you post a small video clip so we can hear it,that would be uber cool.
