this is what i see so far

The DET has oil squirter piston coolers
The DET has a bigger oil pump.
The DET has a different front pulley.
The DET has lower compression pistons (8.3:1 vs 9.5:1).
The DET has bigger injectors.
The DET has direct ignition.
The DET has a variable intake cam, runs retarded at idle, advanced mid range and retarded top end.
The DET has mechanical shim in bucket type lifters with a slightly bigger in duration exhaust cam.

The GTi-R DET has individual Throttle body injection.
The GTi-R DET has stronger main cap bolts.
The GTi-R DET has beefier rods.

Just about all the parts between a DET and a DE interchange

Just about most parts from the R are not interchangeable with other SR20s. Keep that in mind.

Go with a DET rather than a turbo kit on a DE. Just my 2 cents. Others will vary in the opinion, but in the end it’s what your wallet allows and what you feel comfortable in doing. Good luck!

if you have a healthy DE i would just turbo that, but if your de is super high milaged, etc. just get a det.

All of the information you quoted or typed for the non GTi-r DET is from a RWD DET or something. None of that is correct for our AWD/FWD DET's. Minus the oil squiters and bigger injectors.

I would just rebuild the de motor with pistons and rods , and if you plan on just turboing a stock motor i would just turbo the de . Also one advantage to the de block over the det block is that the carrier bearing bracket for the axle is held on by three bolts rather than a det has 2.
