Are these any good ? I've only seen the 2 thickness's that Minispeed sell.

If it a'nt broke don't fix it !!!!!!!!!!!!!!!!!!!!!

No!...... IMHO! there junk and will lead you into problems

you are better sorting the problem at route level ..........................................(ie) altering the combustion chambers

I didn't want to go that far ! why are they crap (Cant take high boost?)

2 chances of a head gasket failure.

Back once again like a renegade master

I assume its a plate and 2 gaskets ? (I thought it was 1 gasket but thicker)

Yes, it's a plate and 2 gaskets. I have one fitted with the Vmax supercharger kit.

Hope to be in a position to change that in the future but won't have the chance for a while so will have to stick with it!

Chris

how much is the kit???

i could do you the work for the same price, postage included ..... maybe!

dont use the decompression plate... my friends had the gaskets go bad and now need alot of work to block and head

imo benross is cylinder head god haha

well worth the money

The spacers are a good idea if you are supercharging an MPI or somthing and want to be able to change it to standard if you flog it, but as above it will be just as cheap to get the chambers enlarged,

also if you have to pull the head in the future it'll be 20 quid a time rather than a tenner!!

plus with the spacers you loose squish (que Vegard lol)

To be fair, I know of a lot of VW people that use these to good effect.

Hi,
Alex .. I'm sure they do, but A series head gaskets aren't exactly bullet proof in standard form!
Cheers,

My Mini build diary

in principle if you don't got stilly with the boost, I don't see a problem with it.

Best 1/4 mile 13.2 seconds @116 mph
First 5 port miniturbo to make over 200 bhp on a carb?

there isnt a problem with it if you dont go silly wiht boost and your ignition timing is perfect, but the facr is that the a- series head leand itself well to being opened out to lower the CR without bodges like decompression shimms. i have to run a decompression shim (s) and i have had my fair share of failures when pushing the limits. on an A the option of openin gout the head is right there infront of you, making decompression shims a very lazy mans bodge.

Gav - how much cc do you need? - you can get A gaskets with 12cc in them

If Carling made Mini engines
it would probably be like this one!

Well John all I know is the engine is 1293 and as far as I know the head and and deck hight are standard. I was probably looking at 15psi with the charge cooler system.

Gav - do you know what piston dish you have - and is the head "n/a" style?

If Carling made Mini engines
it would probably be like this one!

Don't know pistons until engine comes out in about a month, and head is a standard turbo.
