wat bolts do i need to use these ? wat size or where can i buy them i have the adaptor plate but come with no bolts

Im pretty sure its m10s mate, but someone will confirm this for me shortly. If not, i'll go and try find the ones i got and measure them for you.

just the standard 8mm stud and nuts are fine. Apart from one which has a 13mm head with a female thread.

martinmilne

will they fit looks too short once the apaptor plate is fitted?

i got mfi head adaptor plate then efi inlet

s1cab

iTrader: (1)

i've never had any probs had efi inlet with the adapter plate for a mfi head for a few years. fits fine. i have got the studs wuth the female torx head on them though? think they may be zetec?

studabear

I re cut the existing mfi studs as thethread wasn't long enough, then the other 2 I bought long m8 bolts and made them into studs

thats what happens if you buy cheap shit parts off ebay. You dont get what you expect and end up with a steel plate instead of alloy.

martinmilne

its second hand part i got off a mate who got it of you jano but kept studs in his head

why not ask your pal what size studs he's using then mate?

They are M8, just pick up some longer ones as the standard ones are indeed too short.

Versus_Creations

iTrader: (1)

ok i deserved that one.

But hey really he should of got the studs with the plate.

dave_s2_rst

iTrader: (2)

lol at the above!

But do agree, there are some shite ones on ebay. Brought one which was bent!useless piece of rubbish!

Karlos G

iTrader: (4)

Luck of the draw I guess, mines an ebay one made of steel, came with the studs though and performs flawlessly

Versus_Creations

iTrader: (1)

steel ones are not great for manu reasons. The main one being how the injector section has been drilled in a very crap way. The next is its steel which holds heat and makes it worse for heatsoak and cooling. Not to forget the extra weight which is a joke.

Made from a fivers worth bit of steel. Its a joke.

Im going to put mine on ebay just so people see what they should be like and so that they stop being had over by the crap ones on ebay.

Classic thread.

crazycage

must admit a certain bit made me chuckle

Karlos G

iTrader: (4)

"injector section has been drilled in a very crap way" what exactly does that mean? lol Lets see some pics of yours please.
Heat soak on the inlet side?! LMAO The air is not there long enough to heat up.
Extra weight?! Must weigh maybe 1Kg tops, for 99.99% of us that makes not difference what so ever.

Come on Jano, that's got to be the worst argument for buying your adapter plate (which is 3 times the price) over an ebay item! lol

martinmilne

where can i get these bolts from ? do motorfactors sell them ?

Versus_Creations

iTrader: (1)

Karlos what type do you have and have you compared many back to back. You say you havent noticed any heat soak. But how would you know without fitting a guage firstly, and also test it with an alloy type i make.

I have over 5 conversion plates i have removed off various engines over the years where people have either tried to make their own, or bought crap ones like i mentioned. I wouldnt of made such a point if there wasnt a reason for it. You should know me better by now.

I have seen ones with no tappered injector section and is just drilled out. So that the fuel will hit a flat section of burning hot steel then drip into the port.




look at the state of the quality? Seriously!

You know i cant post pics of mine on here due to trading etc. So either compare them with the ones on my site which are in the ODDBINN for everyone to look at and understand why not to use them.

Karlos G

iTrader: (4)

Mine looks very similair to that picture above with tapered injector cut outs but my 'ports' were polished, I have not compared any back to back no, I have looked on your site for pics of yours but only found your EFI to MFI plate, assuming the MFI to EFI one is made to the same standard I see no difference except yours are ally.



I have not meassured ACT's before and after the plate but I'll stake my left lung on it making 0 difference being steel instead of ally, after all it cannot be any hotter then the head can it?! lol

Versus_Creations

iTrader: (1)

The above plate is for an EFi engine using an MFi inlet, it has none of the important injector cutouts that we are talking about.

It is however 12mm thick, making the ports longer for better flow. Also is a perfect match with the gaskets, so if you have a decent head like i offer it will be a perfect fit with no steps.

If you like ill email you a decent picture and you can post it up for me, so that people will understand exactly whats right and wrong. Then maybe you will finally agree and stop this argument going any further.

You say it wont make a difference being made from steel or alloy. But if you think about it of course it will. Steel will hold heat longer than alloy. So of course it will make a difference.

email me if you like and ill reply with a picture for you. jano@oddkiddcreations.co.uk

like i said before, if it wasnt worth making a fuss i wouldnt.

Jano



You havent tried both ways so thats no use to the thread. Also what guage are you using for ACT.

Karlos G

iTrader: (4)

Yeah that would be good as i'd like to see one!

Mine is also matched to the gasket as I run an NMS head and of course wouldnt want to add any restriction.

Steel may hold heat longer than ally but it will never get hotter than the head so it makes no difference, other than when you switch off maybe it will take longer too cool down or perhaps after extended high rpm use it may take a little longer to drop in temp but IMO for this application it's going to make no difference to any of us, also think about the speed at which the charge air is passing the plate... it's just not there long enough to heat up!

Your right I havent tried both ways, and of course my ACT sensor is pre plate anyway so the above quote is irrelevant lol Edited accordingly.

I agree that the injector area machining has to be good, but I think we'll just have to agree to disagree about the heat soak

Email on it's way!

Versus_Creations

iTrader: (1)

Of course it makes a difference. The temp of the inlet manifold will be higher due to heat soak. Yes air will travel fast through it. But being higher is never a good thing.



Good im glad your starting to see the point now. If you post up the pics i just mailed to you maybe others will get a better idea that quality of components is very important.

Karlos G

iTrader: (4)

I dont see that this is any better than the one I got from ebay, if you've seen some that have poorly machined injector cut outs then of course thats bad and this is better.
What this thread has achieved is that people know what to look for when choosing an adapter plate, so it's all good!

Versus_Creations

iTrader: (1)

Exactly that mate, which is why i made a fuss in the first place.

It takes sense and understanding to get a decent conclusion.

certainly a worthwhile thread, cheers karlos/jano. I would have brought that piece of shite on ebay with the dodgy ports lol

cheers

martinmilne

all i wanted to know where to get the bolts from i have a good adaptor plate that come from jano so must be good

studabear

sure jano will supply you some

Ideally the adapter plate would be made of a heat insulating material - so the heat from the cylinder head does not get to the aluminum inlet manifold. I am sure everyone will agree with this statement.

Now, since aluminium is a far better conductor of heat than steel, we should not be using aluminum as an adapter plate.
A lightweight heat insulating plastic would be best.
The downside of steel is its weight. But it is FAR supperior to aluminum as a thermal insulator.

I could publish some thermal coefficients if you want

the holes in my adaptor plate are huge. Defo bigger than the studs. I guess you have to hold it in right place and then quickly bung the inlet on hey? Wots everyone else done?

Karlos G

iTrader: (4)

Er.. no they should not be like that at all! lol
The holes should be the correct size for the M8 studs not any bigger and the plate should sit in the correct place.

s1cab

iTrader: (1)

as above the adapter plate i got from jano was perfectly cut etc and all bolt holes in the plate were the correct size for the 8mm studs.

EssexMikeSi

iTrader: (3)

Hmmmm, thats not very good in the hood lol, pretty sure mine has bigger holes than the studs.

paul0461

jano is definately the man when it comes to do with ANYTHING with cossie management. anyone that knows him would say the same.

Karlos G

iTrader: (4)

That may be the case, but in this thread we are talking about MFI to EFi inlet adapter plates nothing to do with Cossie management mate.
As Perry (Canada1) pointed out Steel is a better insulator than ally so will actually benefit as far as preventing heat soak goes, the opposite of what Jano was saying.
