matching inlets diy

yes mate wish i had a cup looks alot easier without air con.
You need to match them to the head. So without removing the lower one it will be pointless IMO.
It's is certainly worth getting this done on the 172 models, specifically the ones without RS stamped inlets.
However don't match the lower while it's still on the car - only one place for the swarf to go & as observed one of the most beneficial parts of the matching process is between the lower and the head, an area where even the RS stamped inlets aren't exactly good!

the lower one is fiddly, bit of a job if you havent done it before, hard bit is getting it back on with the gasket lined up correctly
I can get inlets matched for 100 quid. Close mate of mine builds race engines, he had a look at mine, and matched them for me.
Worked for Anderson race engines, and now works for JB race engines.
He will also do heads for 300 each, which includes bead blasting and acid dipped. Skimming will cost extra.
If anyone is interested, just drop me a PM

what ever pal u clearly know nothing i need to know so go and bragg about your 197 on somebody elses thread!
I think what he is getting at matey is just boring them out to a larger size isn't the best thing to do, you want to match all holes to the size of the holes in the gaskets, any bigger and the gaskets wont seal
Its also more of getting the mani holes to the same size, making them bigger will help, but the majority of upper and lower mani's are different sizes, which will not help airflow

i have only made it 4mm bigger and then blended in with a pencil grinder so hopefully i wont of lost any swirl cheers for your input , how come i would loose torque from boaring out too much?

If anyone wants a set to practice on let me know i have lower and upper for sale
in theory, the larger space you have to fill, the longer it will take to get the air to fill it, but once your going ( ie higher up the revs) it shouldn't makle too much difference.
I wouldnt worry anyway as the std inlets are not that great, matching is good, but thats as far as you really wanna go

thats what i have done by boaring them out i dont mean ive made it massive i made them 4mm bigger which is 1mm smaller than the gasket, i now need to do the lower inlet to the head and the top inlet i will be doing them all to the size i have done the top inlet is that not right?
You don't match them to the gaskets. You match them to the head!!!!!
