Searched for other threads about this, but the only one i found was from 2006 and there was only a couple responses.

Anyway i'm thinking about picking up a built 2.3l motor from someone i know. it has around 5k miles on it. (currently im running a stock motor with kelford 272s and e85)

Anyway im wondering how reliable these engines are, i don't want something that is only going to last 10k miles or something like that. I won't be tracking the car or anything like that, just my fun street car that i put 5-7k miles on per year

So post up how many miles you have put on your 2.3l build! Or how many miles you put on one before it crapped out

Thanks guys!

 

Over 1000 miles on mine so far with 500 whp. And one track day.

It depends on how much you push it, the builder and what's in it.

Was the rotating assembly balanced, does it still have balance shafts?



Lots of variables, I keep to 3k oil changes or less and good maintence overall. I don't see why it can't last 50k+ being a street car!

This is Anthony btw with the widebody Evo 8, glad to see your going to a stroker, pm me with and questions!

 

A buddy of mine is currently around 20k miles on his built 2.3L motor and he hasn't had any issues. It's a 2.3L stroker with a FP Green and S2's. It makes around 520whp/520wtq at 33psi. It's a street car with plenty of runs down the 1/4 mile as well as highway pulls. Like I said he hasn't had a single issue.

 

Thanks man. Yea you are on the Sac Evo Owners facebook right? i'll have to find out about the balance shafts. It was built by FFTEC though

 

There was a thread a while back with some decent information. Not very high mileage engines to speak of in that thread.

There is a local guy that has an Alum. Rod 2.3 RPM motor and it has 35k miles... The other 2 2.3L cars I knew of running around 1 lasted a couple thousand miles (Justice built motor) and the other lasted about 28k (JAM)... with that said I completely blame the tuner for those 2 failures considering they were rather inexperienced and had him do a "kill mode" map.

 

My AMS 2.3 has around 25,000. Its 8 years old and has over 600 1/4 mile passes on it. Never made under 700hp in the 8 years I've ran it!

 

Wow!

 

That's what a $18,000 crate motor will get you

 

Awesome sauce! I am hoping to get similar results. I have 10k on my 2.4 so far. I did kill an oil pump from over tightening the timing belt. I was in a time crunch and just made it tight. I paid for that mistake. I forget and ran it for about 4k miles until the damage ruined the pump.

 

7k here on a 2.23L 4G64, in the mid 500's on E85.

 

Pretty vague question really man. What 2.3L kit is it, who built it, hows it been tuned , what parts were used inside it, how hard a life has it had, how much power has it been producing, how often is it serviced... I could keep going..... Pretty sure ya picking up what im putting down, SO many variables to how long an engine will live.
Either way if you pick this motor up I hope it lasts dude!

 

It depends on a lot of things mine lasted a very long time made 600,700,800 hp on the same engine ran 650ish on pump gas never had to take the head off.

 

there are many factors that effect how long the engine will last. i will touch on a few.

low rpm TQ is harder on a motor. so turbo size affects how much wear and tear there is. big turbo setups will last longer. because you wont be making big low end TQ numbers and the engine wont see as much TQ overall.

fuel used. alky injected cars are hard on cylinder walls. the oil film is washed away at boost. and the alky dilutes the oil extremely fast. I suspect e85 is equally as hard on internals

highway driven. and duty cycle. if you highway drive your engine has a chance to clean itself and polish surfaces. this is good for next time you drop the hammer.

oil temperature. its impossible for me to wait for oil temp to be at 180. my vehicle is short errand car. no way can i am not go into boost while oil temps are low. so driving habbits are huge and differ greatly from person to person.

I have been through a half dozen strokers. at 450-600whp. I get 15k-20k out of an engine before it needs to come out for a rebuild. thats with alky injection, no highway miles to speak of, hitting boost hard when cold, and fast hard hitting TQ that is impossible to stay away from.

this question is as bad if not worse than asking how miles a clutch should last.

 

Thats for a valve cover to oil pan motor!! I dont have anything close to that in to mine
