LeoneTurbo

I very much doubt they will be available.

Amazing! Looks like sales catalogue pictures :-)

Either excessive wrist pin play or worn connecting rod bearing.

OK I didn't know that. Unfortunately I forgot to measure the thickness of the (original) EA71 and EA81 head gaskets when I disassembled the engines. I have also just ordered a EUDM 85-91 EA71 piston, it has an 'AA' partnumber so I suspect it will be of a similar design as the EA82 SPI but with flat top crown. That would be one great piston.

I can imagine; I have almost every possible JDM sales catalogue for each model year of the 1979-1984 Leone, all EUDM and USDM FSMs, parts books and even micro fiches. Unfortunately I don't have a projector and digitising them into PDFs is quite expensive.

It seems my initial measurements were a little off.

I also have FSM for the FF-1 should you be interested

I had to go on an unexpected business trip, won't be back until Friday evening, so this will have to wait until the weekend.

I just received a new set of 0.5 OS pistons, EA82 flat tops with valve pockets. I'm using them on an EA81 rebuild. This it what I measured so far: 1979-1984 EUDM EA81 pistons - FLAT TOP - 33.0 mm CH 1979-1984 EUDM EA71 pistons - FLAT TOP - 33.0 mm CH 1987-1992 EUDM EA82 MPI pistons - FLAT TOP with VALVE POCKETS - 32.0 mm CH I ordered the EA82 pistons (EUDM MPI are the same as USDM SPI) at Subaru Genuine Parts - Jamie was really helpful BTW. The EUDM EA71 and EA81 pistons have the same part number, at least according to my 1979 parts catalogue. The EA71 has 9.0 compression ratio, the EA81 has 8.7 compression ratio, so the volume of the bath tub in the EA81 heads is bigger. Can post pics tomorrow of all three pistons if you like.

Hi Jamie, this is Marnix from B4 Engine Technology in The Netherlands Congrats on your new ride

Re-installed the das now with digital cluster (which actually works - or so told my buddy who gave it to me). Now it's time to concentrate on the driveline again...

These are the EA71 camshafts you can choose from: 13001AA080 - JDM EA71A - MY84-94 - 87 PS @ 5600 rpm - unknown specs 315105120 - EUDM EA71 - MY79-94 - 74 PS @ 5200 rpm - duration 268°, lobeheight 5.62 mm 415107000 - EUDM EA71S - MY79-84 - 87 PS @ 6000 rpm - duration 296°, lobeheight 6.19 mm 415103220 - USDM EA71 - MY79-84 - 69 PS @ 4800 rpm - duration 260°, lobeheight 5.29 mm 415107000 is very hard to find, as is 13001AA080 I can imagine. 315105120 is easy for me to get hold of (used possibly also new).

EUDM EA81 and EA71 engines use the same pistons (ie. EUDM EA81 has higher compression ratio than USDM EA81). I've never seen EA71 (or therefore EA81) pistons fail because of high rpm's. The EA71S engine with twin carbs spins easily to 7k rpm reliably.

Does a 1997-1999 EJ25 pressure plate fit an 1989-1996 EJ22E flywheel?

Those 'JDM' clearance lights/cornering lights and head lamps are the same as the ones we get here in Europe... If you need a set just drop me a line.

Lower number = taller gearing = less rpm at same speed.

Including shipping, import duty and tax the engines cost me about 750 each (yes US$).

I could not justify the cost of a standalone management to power an EZ30R engine with AVCS so I have chosen to get a first gen EZ30D and run it on a stock 2001 loom and ECU. These engines are cheap to get in Japan (250 bucks a pop) and I ordered a new US loom for under 500 to cut up. Now looking for a used 01 ECU. That means I can/will have to sell that exhaust and get a set of OBX headers off Ebay.

Yes as long as you use the head gasket for those 90 heads. But don't expect any performance gains going this route.

Not wrong really. The EG33 is a very reliable engine (more so than the EZ-gen engines I think) and also much, much easier to get running as you can use the EG loom and ECU. But it's bulkier in every way which brings its own share of problems (weight over the front axle, radiator placement etc).

You can use EA81 top hats on EJ struts, but you cannot use EJ springs and spring seats as the diameter is too large to clear the EA81 wheelwell.

As the EZ30R is just 20 mm (0.8 inch) longer than the EJ-series engines, I don't need a special radiator setup (opposed to the EG33 which is more than 4 inches longer than the EJ). As cooling can be an issue on EZ30R engines I want a good custom aluminum radiator, which also supports the two upper radiator inlets an EZ engines requires.

Yes sir... I already have the engine and the exhaust, I'm still saving up for a standalone engine management system (Syvecs or Link). Will be doing a trial fit next month or so when the original engine is out for a more potent JDM 2.0 DOHC (150 hp) so I can measure up how I want the radiator to be (custom) made.

I have a R200 plated LSD off a 89 300 ZX Turbo for my 84 Wagon. I also have the Nissan CV axles. I'm going to have new rear axle spindles machined so I can use those beefier Nissan CV's as my wagon is going to have about 300 lb-ft on the rear wheels only...

This is my 'new' daily driver since beginning of this year: It's a 94 Legacy 2.0 sedan. Unfortunately it left the factory with front wheel drive only but I corrected that issue quickly with a 93 Impreza 5MT AWD transmission with 3.900 diff. In the back is a R160 3.900 plated LSD which came on my 84 Wagon (which is getting a Nissan R200 plated LSD). I have converted it to LPG which roughly halves fuel cost. Since I do about 50.000 km a year (over 30k miles) that is an issue with gasoline prices at about 1.80 Euro per liter (almost 6 bucks a gallon). Unfortunately that fual consumption issue is about to get worse next year...
