My Popped Engine Explained!

[TwistedHumour]

Got off the phone to Pip a bit earlier and he told me what happened to my car…

Apparently, one of the injectors on the front rotor decided to stop injecting - resulting in a buggered apex seal!  Rotor and housing damaged beyond repair  Apparently about 1 in 5 of this type of injector packs up at sometime in their life â€"he said that he will no longer sell them.  I’ll check the make of them with him and post it just so people can be aware (if you aren’t already :p)

So a new rotor, rotor housing and uprated bosch injectors will be going on in addition to some porting work and depending on my bank balance water injection.

Cheers again for the help and support provided when it went pop â€" hopefully I’ll be able to make it to one of the next MRC meets.

Best bit is, it can be ready as soon as this weekend

Every event has a bright side!

Was it primary or secondary injector? If secondary, what size?

[TwistedHumour]

Not sure which one - but the car has 1300 secondry injectors.  Duty would go to about 85% i think

[nikp]

you could find out a bit more about these injectors please? It\'s just that I have a set of \'uprated\' secondaries, which are basically bored out standard set, and i have heard horror stories about them. Although think they might be 1200cc - so would appreciate findout out more about yours, as they might have been the same type.

aaaaaaaahhhhhhhhhhh the RC 1300\'s secondaries which are rebored 850s, yep it is a common problem with them they reach a certain Injector duty and are forced closed.

Glad you found the cause

[TwistedHumour]

Nikp - Yea will do.  Need to phone Pip today/tomorrow to confirm if I\'m getting water injection done now or at a later date so I\'ll double check then.

Blitzboy - sounds about right.  I am glad I\'ve got to the root of the problem.  Getting some nice new bosch ones put in so shouldnt be a problem anymore.

[BlitzBoy]

Yep get that WI fitted one of the best mods you can do on a turbo Rotary

[TwistedHumour]

Is it worth getting it done now, or waiting til the engine has been broken in?

Cheers

[mikeyh]

how much to get it done(unless you can do it yourself)
and whats the benifits on it?

[Laeeq]

Its all about how much you wana spend???if i had the funds available then i would get it done now by a pro while they put every thing back together but you can get it done afterwards...just before the remap...and then happy days again...:burnout

[BlitzBoy]

yeah get it done now as the engine is out easier for them to fit it

[TwistedHumour]

Thanks - looks like I\'ll get it done now.

One thing though - I\'m not getting it so I can run higher boost...well not yet.  Its going to provide me with peace of mind, and as a safety barrier.

Perhaps in time... I\'ll increase the boost :p

[BlitzBoy]

yep its a very good safety barrier in case you get a lean condition it will save the motor

those injectors are a bastard. They are really popular because they are a straight replacement, no new fuel rail etc, judt frop em in. IIRC it was a certain batch of them that went screwy -- There was a world of hurt over them over on RX7club

Funnily enough we were talking about this at the Dartford pub meet last night.  Clive won\'t supply 1300s any more as there have been too many failures.

Makes me glad to have the 1600\'s in place
