so is the toyoya engine "bulletproof" to date ? - v ote now
Discussion
Ask Gooby - he was the first person in Europe to blow one up - look under threads from about 9 months ago relating to this. There is a nice snapshot of his empty engine bay.
Everyone has their preferences - some like the peaky kick in the back nature of it, others not. For reliability, so far better than the k in many respects.

Its Bullet resistant, would be a more realistic expression.
Gooby's issues were to some degree self induced, I'll leave him to explain more. I have heard of others having little niggles, myself included.
The engine itself,is ok, but my ECU and overall running of the engine has been promlematical.

We do jest - toyota engines are really tough. You should not have any problems. Gooby has been conspicuous by his silence (he has been busy rather than taking cover).
Sifting through the anecdotes and heresay, one fact seems to have emerged: If while driving your toyota engine you should glance down at the rev counter and it reads 9500 rpm - THATS BAD.
You may say impossible, but isn't and is bad nevertheless. I was in a VW beetle years ago where the driver made a downchange from 4th into 1st gear. The conclusion involved oil, smoke and a large hole in the side of the engine block! The yots engines are pretty tough though and don't need the same looking after as a K series.

i feel pain for the 111R bunch Beachbum has the correct description "bullet resistant".
It is true that my failure was self induced but it does show a weakness in the engine because I am assured it is a reason for many of the faults in the states.
The engine is unable to handle over revs. A large over rev or Buzz will destroy the botttom end (surprisingly) of the engine.
Basically to keep it bullet proof - when you see the change light, change.

Guys this is an OCR scan of an old ECU printout. As a few of you may know there has been extensive engine work since this was taken - the eagle eyed of you will see why.
This is an OCR of the "reciept" so there are some errors and obviously the higher speeds were done on a private road and track.

Told you he would clarify! Thanks Gooby - can't let you Yota boys get only good press. Not that its anywhere near the "grenade in each cylinder" of some of the really high power k's!
Also apolgies for my unfair accusation - "If while driving your toyota engine you should glance down at the rev counter and it reads 9263 rpm - THATS BAD!"

I think they where bulletproof in the car there where build for(toyota) and with that toyota motronic/ecu? but when you change fabric standards(to lotus) you maybe get some troubles??
But still they are a lot better I guess then the K-series. also some countries use other inputs like the USA and others, and that way it also can extend or shorten the life of the engine...its about many factors! but mostly a combination of things(included drivers and oils and respect for engines)

Yes but no failures on the turbocharged versions - so turbocharge yours for increased reliability!
you having a laugh?
two FF converted cars both lunched their engines in NZ so far....
Simon I was definitely having a laugh (hence the smiley faces - though I should have made that clearer) - the stats only covered one engine - and that hadn't blown yet (US stats) - Noone had admitted to lunching a turbocharged engine yet. (but 0 out 1 not exactly reassuring!)

Known a couple of guys in NZ to have small ECU/sensor issues with their engines, but have heard of no serious problems yet with the actual engine... time will tell though.... it's definitely an engine that you can't buzz or it'll lunch itself in an awful hurry.
Having said that, most people over here with much older K-Series cars have had no trouble either.... give the 'yota a few years and we'll see how it copes with extended Elise use, I think it'll stand up reasonably ok.
Given that I know plenty of Honda S2000 engines that have lunched themselves with a bit of track use, I don't think the Toyota engine does too badly, given that it's bound to get more abuse in an Elise than a Celica.

Really? That is an engine with a great reputation - what sort of failures have you seen?
