Adding a qt. of oil every now and then hasn't detracted from my enjoyment of the car one bit. Oil is cheap.

well it sounds like their is no such thing as a 400whp(built block) daily driver lasting up to 100,000plus miles then huh? How do the Evo's do it? Is it because its a stock fully forged inernal motor?

I'm sure there are a few around. OTOH, the couple of EVO's that I know over in Portland area have pretty much the same issues. Moreover, I don't think Evo's come out of the factory with forged pistons either, but I'm not 100% positive about that; however, that in-line iron block is a stout platform to be sure.

Typically on our race car we do a complete disassembly at the end of the season to measure and inspect everything but we don't change anything but the rings (hone) and gaskets (skim the head) (unless something broke of course). We do this so we can actually get long term data from our engine program. If you replace everything with new parts you'll never learn anything about the parts life cycle under extreme circumstances. If the car doesn't see a lot of redline use or as much heat and HP it will last longer. Frankly some of the newly builder X motors we've torn down have such loose ring end gaps they would be like stock motors with +100k miles. It's no wonder people complain about their built engines burning oil |

what about the HP levels of the cars along with the miles put on the built motor. HP and boost level, assuming good tune, would have a direct correlation to the longevity of the engine. Just curious.

I have around 4k miles on my rebuilt rebuilt rebuilt 2.5L... more than half of those miles with 500whp+ on tap. 540@23-24psi on 93, 61x@26-28psi on c16.
cp 100mm pistons + swaintech skirts pauter rods stock crank stock sleeves headwork+cams/valvetrain 35r+huge fmic It's the same motor I had that broke a camshaft in half @ 6k miles and a blown hg 2k miles later. The block was rehoned, heads resurfaced, one piston was replaced, all four pistons had the skirts coated, new rings, one rod had the small end bushing "fixed", the crank was machined for undersize main bearings, and that's about it besides new headstuds, gaskets, bearings, t-belt/tensioner, and little things. The heads were in great shape after all the problems and I was very happy about that. |

Spot on. I tore down my 08 STI CP Piston block, and the end gaps were just a bit under 2 thous more open then when I put the pistons in 12k miles before. This was a hard 12k miles mind you, and an eventual overboost to 28psi cracked a cylinder liner, but the pistons looked perfect. Jeff |

If the concept of a built motor not having a 100,000 mile life span is a surprise to you, indeed you should not have modified your car at all. The idea that this is a surprise is a surprise itself. It is unfortunate that so many places do such a poor job of educating customers. I always start out my ‘so you want a 400whp car’ with the required ‘do you have your funds set aside for the engine rebuild next year?’. Jeff |

Gee, Jeff, talk about a face full of cold water! So you think 50K miles is an unreasonable ballpark number for a built, 400whp street motor, or is this just a small dose of hyperbole?

My point is really to make sure the customer understands what he is doing. He is increasing the HP of a factory built and engineered motor by more then 50%. There are thousands of engineering hours that have gone into the original design and it's limits. A speed shop build up does not generally have that kind of research and development behind it. The real cold water is when the engine breaks and they have to sell the car at a loss because they can't afford to fix it. Jeff Last edited by sponaugle; 04-09-2009 at 12:43 PM. |

Gotcha. There have been a few of those on both boards, and it makes for depressing reading especially when the car is heavily leveraged. Thin wallets should avoid this game altogether...it's not a matter of if, but when.

Or is it unrealistic to expect any non-OEM engine to survive to a ripe old age? |

Bingo. As we all know it certainly will be stronger and able to withstand more punishment, but the concept that it will also have less longevity than the OEM block is a little tougher for a non-mechanically inclined guy to wrap his head around. In a race car, where the time between refresh/overhaul is measured in hours, this is just reality. Even 50K miles is a LOT of time for an engine that is putting out 3-4bhp/cu. in.
Heh, mention that kind of time to race team mechanic and he'd look at you like you have rocks in your head. |

Anything 50% over stock will not be manufacturer's longevity no matter what...
