turbo qustion

[apintojr]

which would be better. Adding a turbo to the sr20de or swapping the engine to the sr20det?

[frogg]

I believe adding a turbo will give you more performance at about the same price. I would add a SR20DET if my engine was shot.

I was of the impression it was better to change the engine. The DET has piston skirt oiling spray thingy's, lower compression pistons, higher volume oil pump (or so I'm told), different cams and oil return lines for the turbo. I've heard that the rods are bigger on the DET, but I've also heard that they're not - so who know's. Nothing you couldn't do to a DE engine, but just easier to bolt a DET in, I'd think. The clutch is bigger on the DET too (9 inch as opposed to 8.5, I think).

I would blot on a turbo instead of doing a DET swap if I had a 99+. The reason for this is because the Blue Bird or GTI-R engines are much older and you dont know what the people were doing to them before. I would only do a swap if I had high miles or my engine was dieing.

I agree with the point that an older engine might be less reliable, but I like the idea of having an engine purposely built for a turbo. The engine will not need any more building up. Basically, you don't have to worry about alot of excess engine work that you might have to worry about if you bolt a turbo on your existing engine.

That depends......

Well, if you can look at the engine before you buy it, you can check out what kind of condition it's in. Like how many miles it has, does the block look stressed.

Depends upon a lot more than that.

BTW, what does a stressed block look like?

Look in this sub-forum for two threads....

"SR20DET's" and "How to choose the right turbo!"


Also, apintojr. which town in NJ are you from?

Because your answer isn't helpful.

Unless the part has already failed, you're not going to see anything visually. Cracks are examples of parts that have already failed. Corrosion is not necessarily a sign of stress. In fact, on cast iron blocks (obviously not the SR20), a rusted block is actually stronger. I don't know the chemistry involved, but it's true.

BTW, how to you tell mileage of an engine by looking at it? You can't.

The bulk of JDM engines have roughly 40k or so miles on them and they were scrapped due to Japanese laws that make older cars worthless because they are so expensive to register. That is the reason for the large supply of JDM engines and other original parts.

I guess I would live in a wack ass town too!

I live in Kearny!


I drive the white G20 w/ the G20.net sticker on my windshield. I have my snowboard rack on top too for the winter (not that we're getting much snow) so I'm pretty easy to spot...

His original question was what is better, bolting a turbo on to a DE, or swapping a DET. My origanal answer was with a DE, you know what to expect from the engine, because you own the car. But you'd have to do work to it so it can handle the power the turbo brings. My point with the DET, you don't know what to expect. You could get a great engine, or you could get a lemon.

Oh, I'll definitely buy that.

But, I think the original question absolutely cannot be answered because there is not enough information to draw a conclusion. I've been waiting to be asked "depends upon what?"
