Stroking
Hi, I recently purchased two 280zx's, one 81 n/a with a good body, and one '83 Turbo with bad frame rust. My plan is to take the turbo motor, build it on an engine stand and then drop it into my '81. I am about one week from starting the rebuild and I have a question about stroking the engine.
My friend that just rebuilt his 280, (tomorrow we hope to fit the new drive shaft on and break in the motor before our weekly car group meeting) says that there is an old Nissan Maxima that uses the same engine as the 280 but runs on diesel. The engine code is L28DET or L28DE. ??? Im not sure. Have any of you changed the crankshafts from this car to your 280? Suppossibly it will move the displacement up to 3.2 liters. Please give any experiance and knowledge. Thank you.

Yes, there was a Diesel Maxima. By stroking and boring the engine you can get as much as 3.1 L
The 1st Generation Maxima was made from 1981-84. It had an L24 straight six and was RWD. The Diesel maxima was a stroked 2.4L to come out at 2.8L with very high compression. I think it was only made for a couple years. Maybe 82-83. The cranks go for $250-300 on the internet or from Datsun people who know their valvue. Might be cheaper to buy it from a yard or even buy the whole engine for 200 from a yard. (if you can find one)
This requires you to collect certain pistons, connecting rods, and grind some of the block for clearances. Here is a huge writeup on the whole process which has many ways to do it. In your case, you can build the engine with a slightly lower compression ratio knowning that it will be turbocharged. I think the cost of doing this buildup is fairly expensive, but not much more expensive than doing a full and proper L28 engine rebuild. The turbo equipment will be additional cost on top of this.
