I'm just looking for some honest opinions here. would someone be better off taking a regular SR20DE and adding an aftermarket turbo set up or buying an imported SR20DET? The DE is fresh off a rebuild to factory specs, no big dollar rods or pistons or rings just what Nissan said the DE should be built to.
i would search about it, but if you buy a det heres the advantages.
-oil squirters
-lower compression 8.5:1 instead of 9:1, you can use 9:1 and have a nice motor just have to have nice tune.
-already has oil/water lines, dont have to tap for drain.
-the cams in the det are deT cams, designed for forced induction.
-block is built for boost. ive seen 2 de's go bad, one jdm and one US, both were setup right and when broken down had blown ring lands
cons
-cost, ecu, swap, sensors, possible bad engine

Option #1 of course. That's looking at it from overall cost and time to do the work. Bolting a turbo kit onto a SR20DE takes alot less time than doing a motor swap.
This topic comes up every few months and there are pro's and con's to both... just do some reading through the turbo section to get a better idea of what it takes to do both.

Um, the stock DE is 9.5:1, not 9:1.
The DET cams are nothing special... small if anything. The stock DE cams are an improvement over the DET cams if anything. Don't forget adding JWT S3 or S4 cams to a boosted SR20 does amazing things for the topend... and they weren't designed for a deT as you put it.
Regarding your block is built for boost, and the DE will fail comment... sounds like user error. I've had two, no three setups over the past 5 years that were DE motors turboed and none of them failed. I also track my car on a monthly basis... which is more than most do with a boosted SR.
If you are planing on something like a T25 or a T28, i say just go for one of the turbo kits available on classified section of the forum, and give some boost to the DE if its on good condition. Its cheap and the DE holds perfectly.
I would buy a DET if I want to boost more and use a bigger turbo without messing with the internals.
For a hardcore turbo setup changing internals, well is not worth at all to get a DET IMHO, since you are changing almost all of what makes it a DET for aftermarket parts.

det are already boosted, designed for boost, have the application design for boosting. it will be less of a aggravation going with a motor already boosted

that's what the 't' stands for... doesn't mean the SR20DE can't handle boost though.

It will cost more initially. Then there's the unknown is the sr20det you just got have any unknown issues, will it spin a bearing within the first 100 miles of driving it.
The motor he has is running already... one less thing to worry about
the main thing I have to add is assuming this is a FWD you can get a complete det for around the same price as turboing the de, and if you get the ecu you don't have to worry about tuning also if it blows you have the de waiting
Not really. That's a generalized statement. I went boost for under $1200. You buying a DET is going to cost you that, then you still have to pay shipping costs.
i say it depends on what kinda turbo kit you are building if you are building for budget than it could be cheaper if you are building for performance\relieability than i say a turbo kit can run you more than a complete turbo motor

just depends
What's so unreliable about a turbo "kit" pulled from a DET? Just curious.
Turbo your de, you just rebuilt it, so YOU KNOW ITS GOOD. If you had not rebuilt I would say go with the det.
If you really want oil squirters pop your upper pan and head, remove rotating assembly and drill and tap. But there is no need to have oil squirters for a <400hp motor. Are they nice and do they provide peace of mind and better piston cooling, sure...
Are they necessary, no.
Have fun with your snappy throttle response on that 9.5:1 cr with a t28, it will rock at 7psi

If you buy from Tiger Japanese you will be wishing that you just went with your de. I decided to go buy a DEt with my swap and the one I bought from tiger was an absolutely horrible motor.
There were a lot of things wrong with it, but just for starters it had three coin sized pieces of metal int he turbo. I ended up losing my ass off on that motor. Then I bought one from another vendor and that DET was immaculate.
DET is great because everything is plug and play, but if you just rebuilt your DE then there is no contest on which you should use (de)
