Just makin sure

So Jeremiah, I think that you could put in the newer engine


Or, since you can run any Chrysler motor in a DSM (does that mean only 1g and 2g eclipse?, or any eclipse?) you could get a Hemi from a SRT8 300, since it is all aluminum the weight would not be substantial, and make a 500 hp/tq RWD version.

Jeremiah, was your car offered with a Chrysler engine?

I can see his head just spinning now. LOL

Yup, and I understood what john stated first to be ultimately true. I thought that maybe just between engines that came in that generation model, but with the rest of the inputs I am seriously considering this possibility. Lol, on the Hemi, that would be ridiculously awesome. I just want to make sure, and don't know where to go, that this will pass at a national event as smf.

The engine was produced by mitsubishi motors according to Wiki, but was used in a large variety of both dodge and mitsubishi applications.

[c-evoVIII]

The real question is " is it more beneficial to swap engine, or change car??" C

I don't think that wouldn't open up the Chrysler parts bin for you though if in the Eclipse it is a badged Mitsu motor. The other thing to consider is whether the base 4 cylinder motor was a Mitsu or Chrysler. If Mitsu then no hemi for you

Your original swap question would still be fine. Just note that C's last post is really the only wisdom found in this thread

well ofcourse that makes sense, but we aren't looking to make sense here, we are talking about engine swaps . I didn't realize we were talking about competing at a national level. If you are going to compete at a national level event, then you will have to seriously take a look at the rule-set as a whole, see what other cars are competing in your category, and then make plans for your car...Unless you just want to build the car that you already have. However, I don't see the Eclipse being able to get enough weight off, and become skinny enough to compete with the Hondas.
With that said, I do understand the desire to just build the car you want, make it work for a class, and just go with it.

I think you guys are overlooking a key part of the rule ...

Engine block must be a production unit manufactured and badged
the same as the original standard or optional engine for that model.

I think this specifically says you can swap a different engine from the same model car. For example, you can swap a B18 from an Integra to a Civic, as they are the same chassis. You can also swap a Civic Type R engine from Japan in to a US Integra.

Or, you could swap the V6 Quattro drivetrain from an Audi A4 in to a B5 chassi Passat (they are both B5 chassis). You could NOT swap the R32 Golf drivetrain to the Passat as it's an A4 chassis, not a B5.

STI in to Impreza, M3 in to 328, C63 in to C230, etc ... all those are legal.

S200 in to Civic, LS6 in to Cobalt, Supra in to Corolla, etc ... not cool for SM. (Really cool otherwise.)

I think John was right the first time. You can grab the better engine from the same model/chassis, but not from anywhere in the lineup. Also, not from "corporate" level ... so no W16 in a Jetta.

Yep. What you said was how I interpreted that.

[TouringBubble]

Note that 16.1 section D says the replacement engine must be BADGED the same as the standard or optional engine as the car in question. It does not say you can only use a motor from the same model, nor does it say anything about the same chassis code, year, or anything else.

It does actually ...

1. Engine block must be a production unit manufactured and badged
the same as the original standard or optional engine for that model.

I think that is the confusion. But I also think SCCA tries their best to write confusing rules. We've got to remember ... if it doesn't say it, you can't do it.

As far as the year part ... it seems to me that as long as the chassis didn't change, you are good to go. As model redesigns within the same chassis are generally minor changes, and the definition of model (stated earlier) seems to cover minor cosmetic stuff. So, the CT9A Mitsu would cover an Evo VII, VIII and IX ... not just the 2004 model.

But, as Rod said, it doesn't mention chassis codes specifically ... so if we look at "model" only, does that mean you could put an E92 M3 engine in an E90? IT's a "3-series," right?

[rodhx]

I continue to disagree. It says the engine block must be manufactured and badged the same as an engine originally available in a given model. It does not say you are limited to a specific model's offerings. Like I said before, reading the SCCA's own parenthetical example makes this clear as it specifically states the DSM triplets could use ANY motor from Chrysler or Mitsu. If you were limited to offerings from a given model then their example would say you could use any ChryCo or Mitsu motor "offered in a DSM".

But if I really cared I would ask google, 'cuz it ain't like this is a new rule and actual guidance exists out there somewhere.

Or I'd ask Ricky, who is no stranger to engine swaps

I disagree with you Matt. I think that if you ask a question related specifically to the car model in question, it may help in determining what the rule is saying. In Jeremiah's case, "What company is the manufacturing and badging of the engine (or engine options) in my car (2002 eclipse) from?" That answer is Mitsubishi. Therefore, as the rule reads, a replacement engine block must soley be Mitsubishi. The engine model is not addressed so therefore, that criteria does not have to be met.

If "badging" refers to the engine make, then Mitsubishi is the only criteria that has to be met. If "badging" refers to the engine make and model, then Mitsubishi + 2XJZ78...whatever... is the criteria that has to be met and would then limit your options to only swapping engines that were available for a car's model during the model years it was produced.

I also believe that your examples of swapping engines between chassis's is incorrect. The wording about the car model states that car models must have virtually identical bodies AND chassis. Therefore, using your example you could not swap a better engine from the Honda Civic Type R into an Acura Integra even though the chassis's are the same because the bodies are not virtually identical.

However, if the interpretation that swapping any manufacturers engine into any car they produce is correct, then you could swap the engine from a Honda Civic Type R into an Acura Integra because they are both produced by Honda.

[rodhx]

However, if the interpretation that swapping any manufacturers engine into any car they produce is correct, then you could swap the engine from a Honda Civic Type R into an Acura Integra because they are both produced by Honda.

And this is explicitly allowed by the rule, and provides support for the interpretation Mark & I have.

Also, this would be a 6G72 going to a 6G75 IF i decide to do this.
