IVA test following engine change?

[Stevie_P]

Hi All
After a bit of advice if I may.
My brother is building a Fireblade engined MK (He happened to have a Fireblade engine knocking about and thought why not !)
He's since heard that the gearboxes on these are a little fragile and has decided he may change to a Zetec if and when the Fireblade engine / gearbox goes pop.
My question is, will he have to do another IVA test following the engine change?
Thanks
Steve

No. As long as he's passed an IVA on the car with the fireblade engine in, he can change it for anything he wants and doesn't have to have another IVA.

The only potential problem is with emissions. Don't know what emission levels the Fireblade engine gives him, but any subsequent engine fit has the same emission limit. Won't effect him until his first MoT in three years time but it WILL be an issue then.

Also provided the change does not require modification of the chassis.

In this case it is most likely the chassis was built ready to take a car engine and the bike engine has been fitted to that chassis with the aid of a bolt in subframe.

Not sure quite how the emissions will work, you may just have to convince the tester of the engine age.

Itd make more sense to fit a different bike engine....

Thanks for all the answers.
I agree it would probably make more sense just to drop another Fireblade engine in as they're cheap enough I think.
I think you can get a Zetec engine for just over £600 new from somewhere or other.
This will need a gearbox / ECU etc so would work out more expensive.
As for other bike engines, the price of Hayabusa lumps etc are getting silly due to their use in BEC's.

Wont be as quick with a zetec in unless it's heavily tuned... = more cash. It'll add a lot of weight.


There are other alternatives than blade and busa.. I wouldn't consider busa as I couldn't afford one and blade because theyre a bit down on power and on carbs if the older motor. He could pick a r1 up cheaply enough. Seems quite an odd question anyway as people usually want Bec or cec.. If the blade pops, put a stronger bike engine in. Anyway I can't say I've heard much bad press on them. The gearbox is made to propel a light bike but on the other hand you have much taller gearing in a car so the weight isnt an issue. For this same reason there isn't actually a massive amount of stress on the box. Plenty of people run the early blade engines on the road and the 750 motor club RGB racing series an absolutely spank them week in week out. Try it first.

If the car goes through IVA on a bike ngine, swapping -in a car engine with its native ECU is not likely to give you an emissions problem at all; bikes until recently have had rather less stringent limits to pass.

Google for the MOT tester's manual - it's online and then you can work out the standards either version will be tested to. Either way, the likely requirement where engine age/provenenace is unknown is *probably* the post 1995 default limit: at fast idle (2.5 - 3K rpm) CO% <0.2 + HC <200ppm; at natural idle CO% <0.3%.
