Err um, well you see, it's like this....ummm, no! Sorry guys I havent' gotten around to it. I should have a Nology installation, test and feedback page soon. There is still a lot to do but haven't gotten around to it.

I am also aware that I would have to upgrade my auto with Level 10 parts. But would I need a Performance Automatic Transmission (the full custom one that cost like 2k) or would I just need a Performance Transmission System™ Kit (the one pictured below). I would be using the bluebird set up and wouldnt be going past 225hp.

FWIW folks, it still fits with #1. So why go DET? To replace a high mileage engine and/or minimize some of the mechanical complexity (for some) of figuring out how to run water and oil lines to and from the turbo.

So what is considered a "high mileage" engine to replace?

I would consider "High Mileage" to be 80,000+ miles on the engine!

Thanks Louis and great write up. Very helpful.

He's got a turbo'd SR20VE with an automatic upgraded by Level10.

What is this J-Pipe you speak of with the GTi-R turbo setup?

And also, I see that the complete SR20DET engines(from the Bluebird, for example) come with equipment not included in the turbo packages(like oil-to-water oil coolers and sodium filled valves and lower compression pistons and "oil squirters"). It seems that these items are present to make the engine run better and also to prevent overheating or other problems associated with driving an engine hard. Can this equipment be added to a U.S.-spec SR20DE?

I'm thinking that trying to do so may drive the price up to the point where just getting a JDM engine is a better idea.

Thanks in advance.

P.S. How does one adjust the boost level? With the ECU?

It's an elbow that comes off the turbine housing and connects with the downpipe. It also is where the O2 sensor screws in. The BB DET also has one.

It certainly can. If you are going to run DET levels of power, just get the DET. If you are going to build a psycho fast engine, starting with a DE makes financial sense. JWT can add the piston coolers, provide lower compression pistons, and some folks have even removed their oil coolers.

The boost controller interrupts the signal to the doohickey that actuates the wastegate. By interrupting the signal, it can provide any signal it wants, thereby leaving the wastegate closed until it reaches the specified boost.
