Please explain this one!!Originally Posted by AFSil80
I have done many redtop s13 swaps in s14 's. All of which have been strong. Keep in mind they all were done right and tuned within the limits of the stock engine. I prefer s13's way over nissan's attempt at a wanabe honda vtec. IMO
I agree with the logic of newer is better but that mainly relates to the law of averages of getting cleaner lower mile engine. I would have to say the black top s13 is the way to go if you plan to mod it. This doesnt mean you cant find clean redtops. Its just a gamble but all used engines are just the odds or better with newer. Two weeks ago I did a redtop in a s14 that had to be the cleanest engine I have seen yet. I would choose the S14 only if you plan to leave it stock!
No matter what engine you get you should recondition it before is goes in the car. 80% of people think they can throw in a 10+ year old engine in and expect it to run like a brand new engine. Sure its only got 50k but its 12 years old and time is hard. Rubbers and plastics get old so replace the seals.
The oil sumps are small so build up is common on these engines so flush the engine with a 500 mile oil change after install.
It doesnt matter which car you have as long as its 95 and older. 96+ you can put what ever you want in there and but it will not pass obd2 testing unless you have a guy on the inside or live in a county without testing.
I know this prob doesnt flow smooth but I tried to hit some points. I just get tired of people complaining about bad motors when they dont prep a 12 year old used engine like they should. Then blaim it on the place they bought it from or the engine itself when failer occurs. Damn I just wasted 5 mins of my life!! LOL
