914 2.0 ITB conversion

Figured I'd start a separate thread for the conversion of my 914 2.0 engine from murky Djet to ITB's.

Engine: stockish 2.0, rebuilt in 2001 with (about 4k miles ago) new "euro" pistons, new chamshaft, valves, bearings etc.
I wont be opening the engine to start with, want to get it running again with the new setup before I do any mods.
It ran fine 2 years ago when I started the overhaul of my car so there's nothing really wrong with it.

Parts I have:
Maxxecu, swedish ecu with most bells and whistles.
40 mm ITB's from vwspeedshop in the UK (same as Mario sells)
350cc/min Bosch fuel injectors (Saab 9-5 Aero spec) a tad large but they cost me nothing.
EMPI IDF Type 4 intake manifolds
External Bosch 044 type fuel pump
Mahle fuel filter

Things I need:
Trigger wheel setup, either from Mario or Original Customs.
CLT sender
AIT sender
Trottle cable linkage (most likely from Tangerine Racing)
4x LS2 coils + spark plug wires
New spark plugs
Fuel pressure regulator
Vacuum station


Anything else I've missed?

You will need a TPS and some way to mount it on the TB's unless you are not using one.

The ITB's come with a TPS fitted onto one of them so that should be ok.

I can personally vouch for Mario's wares since I have ALL these on my car. His type4 crank trigger fits like a glove and with the hall sensor has NO interference issues like you have with a VR sensor. Mario's CLT sensor is held with one of the tin screws at the base of the manifolds and has worked flawlessly for me. Between Mario's LS2 coils, his trigger wheel and the Denso Iridium plugs I run, I've never had a spark misfire; EVER. Mario even manufactures really nice LS2 mounts so they are all tidy in the engine bay. I run the Tangerine Racing linkage; just do it, don't think about anything else. Mario can make you a harness too. Mario will also provide top notch customer service and advice as you go too.

Seems like my research to find the right parts has been pretty accurate. Thanks Nate. :D
