I've been lurking around the site on and off since 2006, never needed to make an account until now. I'm on my 3rd 3G eclipse now, and I need some info that I can't seem to find.

A few months ago I bought an 03 gts 5 speed that had a blown engine. Full intent on doing a 3.8 mivec swap on it, but plans have changed due to lack of funds.

Right now all I think I can afford is either a replacement gts engine, or a gt engine. However in my area I can't locate a gts engine that is in my budget.

My questions-
If I put the engine from a gt into my gts, will the difference in compression ratios cause problems ?
Would the difference in the cams cause problems?
Would the install of my gts upper intake manifold be plug and play since my car was originally a gts?

Would it be easier to put in the gt engine along with a gt ecu, rather than get it tuned?

Any ideas or things I've missed feel free to throw in your $ 0.02 .

Any of the 6G7X motors are basically a direct swap. If you go with any other motor other than one from a GTS you're going to need to have it tuned.

Finding a motor should be fairly easy.

6g74 would be your best bang for buck. Plus once you get some more money down the line you can just transfer the 74 parts to the mivec engine.

Hey Dead_Pool. Since we're going to be tuning it anyways, I also recommend the 3.5L swap if the mivec motor is out of the budget. Or even the 3.8L nonmivec if that's not pushing it too much. Car-Part is a good source also. Either way, we've tuned it and are ready for you once the install is finished.

I didn't even think about the 6g74 until you mentioned it! I found one from an 02 diamante with 78k miles on it, and it will arrive Thursday . Codeman, I'll send you a pm with what I'm going to need you guys to tune it for.

What about taking a salvage GTS motor with an A/T and installing said motor to a M/T? I've heard that the crank balance for GTS is different depending on A/T or M/T. What would the repercussions be if any? And would it need to be tuned or ECU changed even though its still a GTS?

I know this thread is ancient but, need some help here. I need an engine for my 03' GTS. No, I don't want to do a 74 swap. This car will be a daily driver. I know these engines are getting up in age so the chances of finding a low mileage used motor is slim. I have called several places and stressed I need a GTS 3.0 and they all try to sell me an engine them not knowing if it is an GTS engine. Does anyone know where to confidently buy a remanu. GTS engine? I would settle for a low mileage used one of the price was right.
