ok guys here's a poll for ya,
how many miles did your engine(s) last till it/they poped?

 

I'm at 110k with bad "O" rings

 

I'm still on stock engine, no problems right now

 

1st motor: (original) 88k coolent seal go bye bye. engine was bone stock. bought the car with 74k.

2nd motor: 112k apex seals fried along with turbo. mostly freeway miles with these engine mods: CAI/DP/CB/BOV/Koyo Rad. running 10psi, sometimes 12.

3rd motor: 45k still rolling with good compression. Same mods as above with new twins and PFC. so far so good <<crosses fingers and knocks on wood>>

 

55k miles on original motor, still running strong (touch wood). Practically bone-stock tho.

 

131,000 one the original engine. The electrical gremlin took her out though.

 

Just recently hit 100,000 on "reliability mods"(fan mod, Koyo Radiator, DP, MP) . Small oil leaks through the oil filter base(fixed) and secondary turbocharger.

 

Repost.

 

yup...repost.

 

its a different kind of repost though

 

besides, i bet more engines blew since the last repost

 

20k total
15k fully moded
5k stock and lightly mdded

The Fd is one of the only cars I know where the vehicle last longer than the engine. As where you can find wreckd corvettes and slowmaros with perfect engines all the time.

 

new engine was put in her at 55k.... i dont know what went since i didnt own the car.. but its at 68 now and running great.... (knocks on wood)

 

camaros/slowmaros? lol, as in dealer/stealer?heh thats a new one
(well at least for me)

 

50k on stock motor.18k on rebuild with blown O ring.

 

First RX-7 - 1st Engine - 142,000 miles with a gigantic boost leak and no 2nd turbo.

First RX-7 - 2nd Engine - 4,000 miles (Pettit Rebuild)...wreck

Second RX-7 - 91,000 miles and still running STRONG!!!

knocking on wood now

So I guess I don't qualify to vote on the poll

1st motor 107k....breaking in my ported motor now...

 

i dont know how far. But my last almost a year. (I remember changing my engine every single damn year)

 

it seems mine didnt last very long just 68k

 

Man a year ago I had great compression and really strong engine.

It took alot of abuse and held up, (also did alot of mods) until just recently when I blew a Coolant Seal. @ 33k miles on a reman

I think at 10-12psi it would have still been alive and strong, but 15+psi really takes its toll on these twin triangles of deth.

 

on my last Fd 139,XXX and still ticking with a 75 psi compression 2 month ago on original and running good with no problems!

 

The Fd is one of the only cars I know where the vehicle last longer than the engine. [/B][/QUOTE]

92-96 Prelude are dad too. I blew 3 motors in 3 yrs! I hate those cars!

67k on stock engine

 

1st engine: @62k miles. Stock, bad O-rings [Covered Underwarranty]
2nd engine: @105k miles. Stock Dealer installed Mazda Reman. Massive front-cover oil leak and possibly bad O-rings.
3rd engine: 6k miles on a Pineapple Street Ported motor with all the reliabilty mods(and all the bolt-ons): Koyo, H2O temp guage, PFC fan settings @ 86 C, EVANS NPG+ Waterless coolant, Upgraded silicone O-rings, Miata thermoswitch(still need to install it)
