Engine troubles

[Madcow1041]

Now that I'm finally back from vacation after a week of peace, I can post about my car. I think my engine has died (for me it's just another excuse to get my new engine . She just decided to start spewing oil everywhere. Luckily it was right around the corner from my house. I was trying to drive, and it all of a sudden stalled. I started it again because I thought I hit fuel cut or something. When I turned it back on, my car was sputtering and when I pressed the gas, it felt like the car was getting almost no power at all.

To deviate from a long winded story, I'm just wondering what (besides the obvious 6-bolt swap things) I would absolutely need to swap in a 2.3. I'm figuring I need at least DSMLink, probably larger-than-stock injectors, and obviously the engine. Anything to point me in the right direction would be great. Need to know what I'm saving for

No input from anyone on the subject?

It's against the site rules to bump your threads. It's best to give it a few days, and if no one has answered by then, try doing some more research of your own and posting up a more specific question. The reason you didn't get any replies is probably because your question is too vague. For example, are you going to be adding any other power mods with your engine swap? Try to offer as many details as possible, and you will get a much better response.

For this swap, I'm not planning on doing any other mods aside from the necessities. I just need my car up and running again as soon as possible with the least amount of money spent, which is not to say that I won't be spending a lot of money to get this stuff. I just need the bare minimum in parts at the moment or else I'll have no car.

Sorry for being vague.

No need to apologize, just keep in mind that bumping can get your thread locked in a hurry.

If you've got everything for the 6-bolt swap in order, you shouldn't need anything else to get up and running with a 2.3L. The size injectors you will need are more a function of your entire setup than just the displacement of your engine. The most important factors include turbo selection and boost level, along with intake/exhaust plumbing and cams. Since the T25 isn't capable of flowing enough to exceed the limitations of the stock injectors, you'll be fine until you upgrade the turbo. With larger injectors comes the necessity for something to compensate them, e.g. DSMlink, but for right now it would just be a nice bonus. I hope that helps, and if you have any other questions don't hesitate to ask.

Good luck!

I was under the impression that with more displacement comes a need for more fuel, which is why I mentioned the injectors as well as DSMLink to manage it. Obviously I haven't done this before, but am I wrong in assuming this? Or are the stock injectors large enough to handle more displacement even if it is just the t-25? If that's true, then am I correct in assuming that my horsepower/torque would essentially be the same (aside from the shorter torque band) as I was making before until I upgrade my turbo?

 

[donmagicjuan]

It depends on how close you were to maxing out the T25 on the 2.0L. With the 2.3, you'll likely see more off-boost power, but you will only be able to make as much top end power as the turbo will flow. Sadly, many people are able to reach this point with minimal mods and a stock motor. The place that a 2.3 will really shine is with a larger turbo. The extra displacement does wonders for the spoolup of a massive rotating assembly.

 

[Madcow1041]

Well I was running 15 lbs of boost. I do plan on getting a larger turbo... Probably a 20g. But like I said, I only want this up and running for now so I can drive my car again

Do you think I would I see a loss or a gain in power while waiting to get the money for the upgraded turbo and whatnot?

 

[donmagicjuan]

It's just my best guess, but I would expect you see a gain off-boost as I mentioned earlier, and you will probably feel the T25 fizzle out at a slightly lower RPM than before. Overall max power will likely be slightly higher, and will probably occur at a lower time until you upgrade the turbo. That's the best I can give you; anything more would start to qualify as bench racing. Keep us posted on how it goes.
