FAQ




Where do i buy this mofo at the best price ?



Gruppe M can be purchased second hand in the for sale section , or here ...

http://civictype-r.co.uk/forum/viewtopi ... 8&t=126243 EDIT ... Sorry the discount option is no more :bigcry:

Either way these go for around the £700 mark . They hold their value so don't expect any major deals





Is it worth the money ?



That's a matter of opinion , at the end of the day the OEM airbox works fine . If you can spring for an expensive induction kit then by all means do so . It has rave reviews and is proven to be one of the best kits for the EP3 . Obviously there are plenty of other systems to choose from so do your homework .



Is it difficult to fit ?


No , all parts are supplied with the kit to fit straight into your engine bay . Its a simple job and takes 30 min's tops . Most of that is figuring out how to build the Lower case and adaptor . Few screws and the OEM box is out , assemble the Gruppe m , then bolt it all in .

( Other parts are recommended which I've listed further down * )


WARNING


Make sure your scoop clears your bonnet before slamming it down , some scoops STILL foul the bonnet and may need minimal shaving off the edges . It's a £50 mistake so be careful

So what else will i need ?? *



( None of the following is a MUST , these are just little mods which we've found make life easier )


First thing is to change the cowl top . the one provided with the kit is not up to scratch at all . It rattles , and looks nothing like the OEM cowl . You can either modify your own by following this guide ...


http://civictype-r.co.uk/forum/viewtopi ... 12&t=72710


OR

You can save yourself a lot of hassle and buy one ready done straight off a forum user , here ...

http://civictype-r.co.uk/forum/viewtopi ... 8&t=128299



Next thing would be to replace the existing cowl screws with either Camlocs which can be found here ...



http://civictype-r.co.uk/forum/viewtopi ... 8&t=118688





Or you can find larger Cowl screws in Halfords , like so ...

Next thing would be the OEM breather hose . The Gruppe M does move about in your engine bay so the OEM pipe tends to split . Other pipes can be sought like so ....


http://civictype-r.co.uk/forum/viewtopi ... 8&t=148302



With the scoop above the bonnet , will it flood ?



No , the Filter case has a drain hole in bottom of it which funnels any water out of the system before it gets into your engine . A brilliant diagram can be found here ....


http://civictype-r.co.uk/forum/viewtopi ... 8&t=159201



How do i clean it ?
The Gruppe M uses a KN filter so KN oil would be the stuff to use :thumbup: . Open the Filter case to remove any leaves etc



Is it loud ?


Mostly in vtec , then it goes nuts



Not done yet , still gathering info ...

[Seiki]

How do i stop it from shifting about ?

There's tons of fixes for this and it's all trial and error , here are some examples ...


http://civictype-r.co.uk/forum/viewtopi ... 8&t=157900




Will Gruppe M fit with any strut brace ?



Obviously not as there's different designs . The GM is quite bulky so you'll have to do the measurements or search really hard for answers .

I will keep updating this part as soon as i find info


E-tech - yes

CUSCO - no

J's Racing - yes

DC - no

Spoon - no

Carbing - ( don't think so , I've searched every page containing Carbing and nobody has done it , that i can find )

Nice one mate

[ryanep3r]

Great Work Mate!
Just one little question I'm afraid, I have my GruppeM on its way but does anyone know of the rough figures for performance gains that it will produce? It will be fitted to a stock car with other mods to follow in the future. If anyone could give me a figure it would be much appreciated.

[Seiki]

You're only looking at a few bhp's ( 1, 2 , 3 if any ) with an induction kit . It's better coupled with other breathing mods ( exhaust , mani etc ) for best results as you probrably already know mate .

[evilowl]

Not strictly true, although the GruppeM will give better results on the road than on the dyno you could realistically expect 10 - 12bhp

[Seiki]

even better :WOOT

[ELGY123]

Awesome thread!!! :thumbup:

[david_s_fox]

Is the Gruppe M generic across the CTR range - ie FN2 and FD2?

Thanks.
