I have a 93 1.8 4-cylinder bmw engine and might want to put that in my bug since I already have a cooling system, big brakes and the workes and my EJ20TT won't work.

Anyone done this conversion or seen it done? Haven't measured things up yet but it isn't a big engine 118hp won't be bad in a lightweight bug.

why wont the tt run ?

had 6 wires on the secondary turbo side melted against the turbo, replaced them and 1 broken injector but ony thing that happens now when applying power to the system is the ECU's relais that clicks and nothing more.

Maybe next week a guy is coming over the check all the wiring and the sensors with special equipment (oscilloscope). Also, since there are very very few subaru's in my country and it's a JDM engine I can't simply take it to the local dealership and have a read out to find the problem.

Convert this to a single turbo , get an aftermarket ecu , and you have 190 at the wheels

TT ecus require the speedo connected from the subaru + the fuel gauge from what I can work out .

you need also speed cut VSS drive

i agree dude, dont cut your losses with the suba just yet,
get your handa on a single turbo, and make or find the exhaust manifold and exhaust n get a new ecu. From there you can buy straight up wiring loom kits which plug right in!

what country you in by the way?

Belgium

My initial plan was to put in a rotary but turns out there only 10 RX7's where ever seld here and my friend had 1 of them + a 2nd engine but he was keeping it as a backup.

If I can buy an intake+ outlet manifold, stock turbo or bigger + an ECU that doesn't require a engineer's diploma to work with I'd swap the bits over but over here there's not even a chance of finding that.
Already contacted outback motorsports in the US and Australia about it without reply

Just thought of something, my TT engine has 4 seperate coils for each spark plug.
From what I've seen most single turbo engine's have 2 coil pack, how will this match up to the spark plugs? I mean are the holes where my coils fit the spark plugs the same as on a single turbo?

Definately go Sunspares in QLD. A wiring harness ready to plug in cost me A$250 with all the instructions for an idiot included. They will have all the gear you need incl. TD04 and stock ecu etc.
