I was having vortech + AEM fitted on my 00 japanese import car everything was with stock exhaust and about 42k on the clock. Anyways the guy phones says its done but its got a rattling sound at 3000RPM says the big ends gone. This happenned whilst he was mapping / tuning its. The cars now been taken apart yet though to check but hes is confident the engine is badly f**ked and wants to rebuild it with stronger parts... I am thinking to get someone else to put a new engine in it...

My questions:

does this happen a lot ?

should I be looking to rebuild the engine or to replace it ? from what I have read a new engine from a breakers would probably be the cheaper option

 

From what I could understand from your post, NO, it is not common for your tuner to blow your engine due to a bad tune, if that was the case. I would take your car, or at least what's left of it, and have the engine rebuilt by someone else. If you think his tuning blew your motor, why would you give him the chance to blow another one? I'm not sure what happend to your motor exactly, but I would rebuild the bottom end (sleeved, forged rods and low compression pistons) so that at least after the headache is over you will have some power and a bulletproof motor to show for it.

 

I'd have some serious questions about the shop. I'm sur eyou signed a disclaimer so you might be screwed, but they should have a heck of a good explination for that....

 

this is in England btw, they just said the car is old (42k ish) shit happens sort of thing!

 

First of all, really sorry to hear this

And second of all if the car has been even slightly maintained, 42k miles (or are you talking about kms? ) is nothing IMO.

I'm at ~91,500 miles and have had my turbo kit for over 6k miles and so far so good Thank God

42k miles (and def. not kms) shouldn't be a problem at all... that shop seriously is starting to sound like they don't know what they're doing...

 

its probably about 45,000miles now the speedo is in KM and its about 73,000 something I think because its an import

 

Well just wanted to check cuz you can change between km and mi and km/h and mi/h in the S whenever you want...

Either way, whether its 45,000 miles or kilometers, on a decently maintained S, that is NOT a lot of mileage...

 

especially in a honda! go back and ask those bloody asswholes what they did!

 

thats is why you don't just trust any shop to do tuning...

 

42,000 miles old?????????

These guys are not tuners but engine destroyers. I would make them pay for this although I don't know the specific details of it.

Unless of course the car was not maintained properly: oil changes, premium gas, proper warmups, etc.
