I am getting interested in a Suby conversion and would like some input/advice on what complete car to look for Model/Year/Options, Engine size, etc.

Bigkat build a 3.0l flat six, I'm building a turbo 4..

For the street or DE I think the 6 is a better option. For shear horse power and upgrade ability the turbo four has a large support group. STI's 2.5 liter turbo can support 400 hp easily..

Depends how big a smile you want or how big your check book is.

Take this for what it's worth...

I'm probably taking the 2.0 turbo 4cyl further than anyone else has in a 914, and if I had to do it over again, I'd do a 3.0 6cyl.

The benefit of a turbo 4 is that if you want more power, its very easy to get. With a 6 you will have a smooth linear power band, but more power is not an easy proposition. As a Subaru guy before getting into 914's, the EJ series of engine's have a phenomenal aftermarket support.

with above comments. However, I'm not clear as to whether you plan to buy a conversion or build one yourself. What will be your planned usage? Will you ad AC later? Will you AX with it? Bottom line is whichever Suby transplant you choose it will be a big improvement. Be sure it gets the Suby 5mt TY75 tranny, as well. The complete package. As a foot note: If your buying one that's been converted I would want to do a test drive in July or Aug. Not when it's cool outside. You want to be sure the cooling system functions properly. Suby's aren't forgiving when overheated.

I am looking to buy a Subaru to do the conversion. I would be looking for a running car or wrecked that would supply engine, trans, A/C & Heat wire harness, etc.

I bought my running svx for 500 and hoping to pick up a 5 speed trans for a couple hundred. All svx are auto but many are sold cheap when the trans starts to go. I see them for 500-1500 all day long. I can change to a newer engine in the future but this one should get me up and running without the hassles of plumbing a turbo 4 or spending thousands on something newer. The fireing order of an svx engine is the same as a Porsche 6. I am using as many prebuilt components as possible. Everything that Ian at Coldwater sellls, renegade hybrid radiator setup and small car will modify the wire harness. If someone makes up a heat and air kit, I'm in.

There is no inspection of antique cars in PA so a gps speedo and regular exhaust will work fine for me.

If'n your going the 4 banger route you'll be able to source a donor car with the tranny. If'n you go the 6 route you will need to buy the tranny separately as they weren't supplied w/ USA 6's. I will defer to others as to which 4 is best (NA or T'bode), The 6 route is as follows. EG33's are cheaper as they are older and they are larger in size and weight. You can easily Mega Squirt these types.
EZ30D's are smaller in weight and size than the EG series + they have timing chains vs. belts and can easily see 250-300K miles. After market ECU's are available but I would recommend the factory ECU.
EZ30R offers VVT and a jump in HP over the D series however these have the immobilizer system which might prove challenging to defeat but I have no experience with the R series so this may be BS on my part.
EZ36R is a maxed out version of the EZ30R with a jump in HP over the R series.
I've said this before but it's worth repeating. Buy a donor car and gut it, sell off what isn't needed. I shopped CoPart for what I wanted. Found my donor relatively close to me which lowered shipping costs. Another thing, look for rear end or side damaged vehicles that will start and run. Avoid roll overs and front end damaged vehicles. The ad will state if it can be driven on the hauler or needs to be loaded. There isn't any additional charges if it can be driven on + you'll know how the engine runs before the transplant.

I thought I read that rod dimensions and and a few other internal engine dimensions are same as well...anyone know for sure? A copy of the 2.7 or 3.0 Porsche motor?

As for the H6 motors, how much heavier is the older EG33?

False.

SVX: 1-6-3-2-5-4

3.3, 3.2, 2.7: 1-6-2-4-3-5

Also, the clys are numbered differently.

My mistake. I'm stil learning.

I've done a couple of engine swaps. I recommend buying the entire car and stripping it apart. If you are going with an aftermarket ECU, the donor does not matter as much.

JDM engines are different (slightly) and the gasket kits are harder to get in the US.

Immobilizers are easy to defeat but you will have to flash the factory ECU to remove it. The flash alone will cost $300-$1000 depending on options.

DBW (Drive By Wire) throttles are cool! My Audi conversion is DBW and it works great! Just like a modern car. In my case there is very little lag from pedal to throttle. They make gizmos to plug into the throttle pedal to improve this delay. I chose not to use one.

I swapped the steering column, dash cluster and switches as well. This may be overkill for most but it is easier than you think. You just have to methodically pull the un-needed wires out of the loom until you get down to a few.

Seems like you are correct and just didn't know it, See post #25 http://www.914world.com/bbs2/index.php?sho...46689&st=20

we have a guy in ATL that rebuilds suby's.. He can buy the car, dismantle, sell the unused pieces and part with some valuable knowledge once you get past his attitude and show him a little green..

We get parts and engines from him all the time..

Suggest you get a copy of the factory manual for wiring for the year of the donor car.

I've got a running EZ30 conversion car. That I'll be selling soon.
Also have a extra EZ30R engine and wrx transaxle with subarugears locking sleeve that I need to sell.

Going to the Hot Rod world.

With the difference in the numbering of the cylinders, It's not even close...

Going off the Porsche numbers, the Subaru would be firing at 6-1-5-3-4-2

I may be confused, but I think they actually do work out according to the diagrams provided.

Ha ha, I had to draw out a little diagram with both numbering schemes side-by-side, then trace them out. It worked out for me that they're the same order. I think. What's bad is that I did the same thing several years ago and got a different answer, so I'm pretty sure but still wouldn't swear by it.

Either way, H-6 for the win

Misery loves company. Since I've gotten older I've the memory of a whatchamacallit.

Porsche firing order or not, the six sounds amazing . . . .
