Frs vs s2000

anyways, i guess 150k really isn't too bad especially if you're not driving it daily. You'd probably never even hit 200k if it's not a daily driver.

My 08 si is at 125k miles and the compression in each cylinder went like this:

1: 221
2: 223
3: 220
4: 218

So yeah, Honda motors are legit lol

I would buy an S2000.


I would buy a laser disc player.


I would buy an IROC.


I would buy polio.




Wait! there is a cure for all of these isn't there.

There is a 200k owners club on s2ki and truly it's not that many people It's the rpms and the cylinder walls that make them not tend to last as long as other honda engines. And s2k drives around at nearly 4k rpms at 80 mph, 3500 at typical highway speeds.

Decently maintained S2000 engines last essentially forever.
And for the record, 75mph is just over 4000rpm, 80 is pushing 4400. Since the internals are designed for over 9000rpm, components are WAY understressed at 4400.

rod stress is not the same as friction wear, which is what i'm talking about.

anyways, like i said, i guess i'd buy one at 150k, but probably not higher than that.

I had an ap1, it's been a while so i don't remember exact rpms but they were higher than my civic which has a type-r 5.062 final drive in it.

I used to own a 2001 AP1 that i bought for 12.5k with 47,000 miles on it. I sold it for 11k with 69k miles on it. If i still had it now i could easily get more than i paid for it lol.

Friction wear on the cylinder walls is still a function of rpm to some degree. Higher rpm => greater piston lateral loads. Maybe not as strong a function as rod stress which varies with rpm^2, but even at the same loads, 2x the rpm implies twice the wear rate. The wear rate of an engine designed for 9000rpm that cruises at 4100 shouldn't be any greater than that for an engine designed for 7400rpm that cruises at 3500 (or whatever rpm the 86 is at at 75mph).

In the end, either way you're designing to an engine life, and if it's a higher-rpm engine of course you take that into account.

I've never heard of an F20C failing due to cylinder wall wear...

It can be more than twice the wear rate with high rod angle.

But either way, the frm cylinder walls aren't what wear The piston rings do. those frm bores are extremely hard.

Like i said, perhaps it's just difficult to find very high mileage s2k's until recently when people that daily drive them to high mileage got a hold of them, but i've seen more than a few s2000's fail due to needing a rebuild because of compression loss from wear.

This is a hilarious conversation. This went from FRS vs. S2000 to how much abuse you can do to the S2000 before blowing a motor. Going through 2 motors on the FRS/BRZ was hilarious...sigh...

The S2K is obviously faster but I'd take a new car over a used car if given the opportunity. Comparing the two is not really fair in terms of motors, but you could've taken the ~12k and completely beefed up the FR-S.

[swpbrz]

no comparison is fair according to this forum. It might as well just be dedicated to frs vs brz if you can only compare cars that are mostly the same...

You cannot make a new FRS + 12k match a s2k.

You're right, it'll be faster than a stock S2K!

I can't wait to read the 48 pages of dis fread.

Plenty of 200k+ high RPM honda engines out there. I have one and another that's very close. Buddy has an ITR with 225k+ that's unopened and makes great compression. ITRs rev higher than that at 80.

Just not that many people that drive S2K's that much to get see that many high mileage cars.

Shutup S2K fanboi!
