Blew My Motor

[Dean_HR31]

This is wrong, this is very wrong.

A week ago driving my R33 for the last day before the new penalties were in force I took my car out for a bit of a

session.. First corner I entered, midway crossed up the car stalled & wouldnt start again...

Got the car towed to my tuner at CREATD motorsport which was just around the corner.. and he just called

me 10 minutes ago to tell me one of the pistons isnt working.. either a broken rod, rod bolt etc, god knows wont know for

sure till he opens the motor..

I am extremely, extremely angry. This engine was rebuilt about 30,000kms ago by

the old owner who supposedly spend 9gz there on the rebuild.. I trusted the rebuild.

Engine is ment to have:

Arias Forgies

O Ringed & fully balanced bottom end bored 20thou with ACL Race Bearings

New Linished Crank

Standard rods & full standard reco head.

Thats all i can remember from the top of my head....

The car is running a Microtech Plug in, with a 3inch tbo back, garret front mount & GT 28 76R turbo

and a Bee R rev limiter.

Car was beautifully tuned on a mild 14psi making 217 at the wheels..

I thought a setup like this should last yeeeeeeeaaaaarssss, since there are so many dudes pumping 300+ out

of there standard bottom ends for so long!!

At the moment im not 100% sure on what to blame, the quality of the engine build or the Bee R limiter.

However, seriously i cant see it being the Bee R since it was only installed on the last tune 2 months ago and i drove the

car twice a week maxxxxx, and i didnt exactly sit on limiters for a laugh when i drove the car & it was also set

at a very low 6500RPM!!

This car was never thrashed for a long time at once, never passed the half way line on temp, and id cruise the car

for 5-10 minutes with the bonnet unhooked after every time i gave it some stick. I treat the thing like a baby.

Thats why i am so angry!

That sux Dean, before making assumptions make sure Rob gives you all the info you need!

[Gts-t]

Bad news man, might be the perfect time for a rb30 though

Grab one and rebuild it to stock specs is about 1-2k. Maybe the shop will help u change it over for a reduced price if u are good mates with them.

Good luck

[R TUNE]

get them to pull it apart and tell you what failed then you can make accusations

[LBR33]

Maybe the rebuild was ok but the piston or rod was faulty

[Blitz]

Where did this occur, on a public road?

[Dean_HR31]

why does that matter..? not being mean, just curious.

man that sux.

went thru a similar experience when I purchased my CBR900RR 4yrs ago, before I knew it the engine was shagged.....

not a nice feeling at all.

[mokompri]

if there was a problem with the rebuild i would expect it to cause issues alot earlier then 30,000km's. Although i can understand your unhappy, i wouldnt make any assumptions till its been pulled down and the cause is found.

[NickR33]

mate join the club... I had about 25,000km on my forged motor (exactly same specs as yours), now its sitting in the garage with a spun bearing...

I did the same as you, assumed I could lean on it all I wanted because I had only 200rwkw... I just didn't look after it properly and was tracking it fairly frequently and it eventually cracked the sh!ts... however I will be extra upset if there is any piston damage like yours

ps. I hope he didn't spend 9grand on that build... mine cost half that

[Ronin 09]

maybe overreving it blew it up?

default position seems to be blame the hardware...

[Dean_HR31]

my bee r rev limiter was set at nothing higher than 6000 - 6500rpm was verryyy rarely set on 7000rpm which should still be nothing for a forged motor!!

What annoys me is i called the builder of this engine a week ago and asked him if he could re write a receipt for all the work done to the motor since the guy i bought it off never found them.... I wanted these receipts simply for the peace of mind and the fact that i wasnt sure wether id keep this car or not with the new laws....

The builder refused to write me a receipt, all i wanted was details of what was done & how much was paid thats it! no warranty no nothing.

All he agreed to was a phone number that the buyer of this car could call to ask what has been done. That doesnt satisfy me, i wanted it in writing.

Is there any reason why the builder wouldnt re-write a receipt????

not sure if they would write you a NEW receipt, but i don't see why they won't give you a print out/copy of the orginal receipts! Unless he doesnt keep copies?

[Starionturbo]

I reckon you are mostly to blame though.

How can you beleive someone when they say they have a "BUILT" motor in it, without seeing actual reciepts.

Even Still I wouldnt beleive it. I would have tested the engine as you normally do (compression, Diagnostics etc) but thats about it.

So many many people Ive known over the years buy a car where the previous owner has said "its been rebuilt with forgies" only to have it blow up shortly after and when pulled down finding that its actually and old high kilometer motor.

The biggest cause of this is that people think well its got a built forged motor there fore even if its running small power I can cain the living shit outta it and itll last forever.

I would never buy a car based on that and actually think its bullet proof. As for the BEE R limiter - do you think the "built" motor is indestructible when youve got it belting on a set limit?
