Porscheru Engine Choices, 2.2, 2.5, or 3.0 ?? Options

The EZ30 is only 1.5" longer than the 2.5L 4 cyl. and slightly heavier. If buying from CoPart, search for "running" vehicles. 2 reasons; 1st you know it's a runner and 2nd, a running vehicle is cheaper to ship. I choose to shop the upper line model Legacy/Outback LL Bean model for my 6 because I figured this model was likely to have been "well cared for".

The one thing holding me back thus far from buying the donor with the EZ30D is the auto transmission. Is this an easy swap to put a 5mt tranny in, using the ECU and wiring from the donor car? I have read that its the same ecu for the auto tranny car and manual tranny from 1999-2004 with cars running the EJ25. Another poster once mentioned that you just have to cut one wire to get the ecu to work with the manual transmission. So is it easy to just swap in a manual tranny?

Its really simple. bolt up a manual flywheel, attach the pressure plate, and bolt on the transmission. The ECU will throw a code for a missing auto (no ez30D's were offered in the US with a stick) but it will not affect performance, driveability, or reliability. there are only a few plugs that go to the auto and you can just leave them unplugged or remove them.

There is no cut one wire and fix the codes though, because the ECU was only made for auto cars.

It's very easy to use a manual trans with an EZ30 engine. Take a look at 76-914 and rnellums build threads. They both used the stock ECUs. You really can't do an auto trans unless you use an older 2WD box, which is not recommended unless the driver must have an auto.

What you need to decide is what level of power you want. A 6 cylinder makes the car VERY quick and fast compared to stock. Lots of fun as long as you are ready for the car to become a completely different animal. If you want the feel of an enhanced version of a stock 914 go with a 2.5.

Do the 6 cylinder fit in the engine bay without having to cut into the trunk floor?

Yep do the six as it sounds like a Porsche ,first one I heard in a SVX ,wow that sounded great,in my country this was the only model using the six.
Now flash forward and several years later the H6 Legacy wagons are imported as JDM and renamed Lancaster in large numbers.
I know little about them really ,but hear the H6 is a well made engine .
A mate had a full on race car that once was a V8 and he is doing a 3.6 H6 Subi with twin turbo's ,should be a great track car.
