SR2x Preferences

[cs_maan]

I was looking online for some Nissan 240sx's and I noticed that some people specifically focus on it being either a SR20DET, or an SR24DET that was going to be swapped with an SR20.

So my question here is, what's the big deal about the SR20 over the SR24? Is there that much of a difference between the two? I'm not too well informed about so forgive me if I've specified something incorrectly.

Thanks for any replies :).

As far as I can tell, the sr24 is just a stroked out version of the common sr20. So if you have a ton of cash, then you can go all out with internals.

Most people just upgrade the turbo, IC, injectors, and ECU on an sr20 and can find some nice power levels from an otherwise internally stock engine. 300hp shouldn't be much of a problem, and in a light little 240 that is enough to get you sideways in a hurry.

So which do you think would be more cost effective in terms of how much power you can squeeze out of each of those (300-400hp) being the goal.

The factory sr20det with some good supporting mods and a bigger turbo should be able to make 400hp reliably on stock internals with only a few grand into it. If you go with used parts you probably could cut that price in half.

Anyways, take a look at this FAQ on nicoclub on the sr20's for more info.

Safe Limits of Stock SR20DET
Many people ask what power levels a stock block SR20 can handle. The internals have been known to support 400 whp reliably. However, that is dependent on your fuel management. Proper supporting mods must be done to the fuel system to support this number, or you will melt pistons. The pistons are the first part of the motor to fail internally. They tend to overheat and either burn holes through them, or their ringlands crack and fall apart.

Wow thanks for that link, its very informative, it should help me gain a better knowledge since I'm looking to buy a 240sx to replace my TL since I want something fun to drive and work on. The 240 seems like a perfect candidate :).
