Torn between T4 power and Suby power, Help convince me to keep it air cooled Options

[eric914]

I have been slowly gathering parts for a suby conversion. I have an EJ20T motor. I have replaced the timing belt and the belt covers on it. I fabricated a custom wire harness for it with the intention of using a megasquirt controller. I have the Kennedy adaptor plate and flywheel. I have also purchased an outback exhaust manifold and braided SS hose kit to relocate the turbo.

The problem is as I get closer to cutting the front for the radiator I can't quite see putting a big hole in the tub. The car is in excellent condition cosmetically.

I also continue to see the power available from the T4 increasing (thanks Jake).

I still need roughly $1000 - $1500 in stuff to complete the suby. I could probably sell the suby stuff for $1000 - $1500.

So $2000-$3000 bucks to play with.

225hp from the Suby

?Hp from the T4 (I do have an Eaton M62 blower laying around????)

So, the question is do I keep the suby or stay T4. Help me decide.

Just my opinion of course and considering I'm just an arm chair quarterback, take my words with a grain of salt, and some tequila. Here's what I'm thinking:

Suby:
Suby fits, will need considerable fabrication for water cooling and water heating in the cabin and for wiring. Even more if you use a turbo engine. If you have to buy new or find used components cheap your cost can vary. Also if you have the skills & TIME to do the fabricating the job will go easier. RPM range about in keeping with existing tranny.

V8:
Big available power with same fabrication, skill, & TIME as Suby. Wiring harness seems simpler than Suby. Need to change tranny to suite lower RPM range.

911-6
Ultimate conversion in my mind since this type of engine is what the "real" Porsches used. Cost all over the place depending on where you find the engine and its size and condition. Not as much fab needed as V8/Suby as no water needed but still fab needed with oil tank, motor mounting, and possible oil cooler. In general may be the most expensive depending on where engine is found and its condition, and whether you can work on the engine yourself.

MassIVe-4
Jake's doing amazing things with this engine and this power plant bolts right in and is still a true 914. 914/6 were rare so 914-4 is what a 914 is. Seems the only downside is that the price comes in one bill. All of the above conversions have many bills that could be spread out over a period of time. There again, depending on what you want to do should guide your approach. If you like fabricating, spending lots of time working on and changing the look/feel of the car, do the above. If you want to swap engines and drive like hell, MassIVe-4 seems like the way to go. I would love to have a MassIVe-4 in my car.
