Good afternoon members. I recently ran my `00 Eclipse GT [Auto] @ Moroso...the 1/4 results were embarresing (or, normal?). My best time was 16.1. The only engine mod(s) I have is an Injen CAI. Anyhow, I desire much more hp than I currently have. My question is: Is it too late to run boost [turbo kit] on my 3G considering it has accquired 70k miles? Thank you in advance for any input to such an inquiry.

Im not sure of the elevation of that track but a 16 second v6 eclipse is on the slower side, most run mid 15's stock or minor bolt ons.

I installed the turbo at about 140K Its around 151K now I think. Thats when the engine came out.

The engine looked CLEAN when it was torn down. The only signs of wear were a couple of stuck piston rings.

I dont know how well the v6 holds up, but the 4G64 is the SWEETNESS!!!!!!!!!!!!

thats impressive you got 150k out of your stock motor. i wonder how long the 6g72 will last me.
150k? not really IMO. The 4g64 is just a bored and stroked 4g63 (IIRC) and that engine was designed to get the shit beat out of it.

There are more differences than that between the two engines. For example; The 64 has a higher compression ratio and an ECU that was not designed around a turbo system. The lower end may be SIMILAR but, they are very different otherwise. SO for the engine to last any considerable amount of miles under boost is VERY impressive when it was not designed for it. Also remember that my turbo system had NEVER even been tuned. I installed it, turned up the boost to 8PSI and ran it. I even ran it at 10-12psi for a few weeks.

My engine looked damn near perfect when it was torn apart, even at 150K miles. I couldnt be more pleased with the capabilities and performance of this motor. This engine can last up to 200K under boost easily if it is not rediculously abused, is well taken care of, and receives a good tune. I wouldnt be surprised to see 300K if it never gets boosted.

Well, I know, but my point was that the 4g64 was based heavily off of and designed from that engine...should have been more specific, I'm just not thinking straight tonight...physics test pooned me :mecry:

:fawk: I've got 2 more years left. But at least this is my last semester of classes I don't need. LIKE PHYSICS FOR ENGINEERING MAJORS WHEN IM NOT EVEN AN ENGINEER. Why a comp. science in software design (think, programming) major needs 2 semesters of physics for engineers, I will never know.

...for the same reason I had to take Sociology and Economics to get a degree in Electronics Engineering. BECAUSE THEY ARE COCKLICKERS!!!!!!!!!!!!

Its good for you though, its excercise for the mind. :twothumb:

I guess....Still, they could stop making me exercise it at that, and not have to also take bio and chem :scream: oh well, nothing I can do about it excpet take the classes and pass them. I don't mind taking some of the classes like pyschology, that was fun. But some of the crap they make you take is just stoopid. Anyway, lets get this thread back on track.

I agree that if you keep your engine tuned and take very good care of it, you should be able to get lots of miles out of it, N/A or not.

Isn't it also true that the pistons in the 64 are stronger than the pistons in the 72?
