Head Skim

[novanova636]

Hello ppl im lookin at skimming my head of my 1.2 k reg. I just dont know how much to take off.

[Ben]

Dont do it then, give it to someone who knows what there doing!

[novanova636]

well im a precision engineer by trade so im no what im doin just dont no how much to take off

[Ben]

as least as possible.

[Shaun_O'Donnell]

Is it generally just enough to remove the effect of the warp?

[Ben]

yes

[novanova636]

so like 10 microns?

[Ben]

How warped is it?

[novanova636]

i want to do it to increase compresion

[meritlover]

you have to measure the deflection then work out how much to remove. im sure an engineer such as yourself will have a suitable engineering degree that would qualify you to carry out this simple calculation

Hello ppl im lookin at skimming my head of my 1.2 k reg. I just dont know how much to take off.

Is it worth it for a 1.2?

[Ben]

Why? What else are you doing to the engine?

[novanova636]

yes but i thought some1 would no already and save my the hassle

Point i was trying to make lol

[novanova636]

was also thinkin of new cams

[Shaun_O'Donnell]

was also thinkin of new cams

A bigger engine would save you a lot of unneccessary hassle

[meritlover]

was also thinkin of new cams

then you must factor this into your calculation as the increased lift and reduced combustion chamber size will result in bent valves for you!!lol

[Ben]

was also thinkin of new cams

There is only 1! Did you buy your engineering degree of the net?

[novanova636]

what the **** is your problem you prick?

[Ben]

Its one of those things, if you need to ask then you shouldnt be doing it.

And the fact that a k reg 1.2 nova is an 8v thus having only one cam i would be intrested to see where you are going to insert the 2nd cam (awaits the reply up your ass).

So by the sheer fact you have needed to ask the question and that you dont know anything about an engine. you should leave it to someone who does know.

[loggyboy]

How ****ing negative are you guys....!?
Dont mod a 1.2.
Pay someone to do it for you.
Dont learn things.

I cant offer you any advice on the amount to skim, but as 1.2 heads are 2 a penny why not just crack on, or just leave it and fit the cams. any performance would be negliable so you might want to consider other options. (maybe c14se head, or porting and polishing.)

[novanova636]

to ben. i never said i was mechanic i said i was an engineer so i no how to cut fu*kin metal you prick. i dont no all the asnwers thats why i came on here and asked for help. yes there is ony one cam but there are afew on it there aint just one big one in my engine is there? um no so more than one cam is cams. am i wrong? if so im ****in sorry.

[novanova636]

to loggyboy. thank you for your advice

[turbojolt]

he is right there are a million different type of engineers out there so how can you have a go like that for asking a question

[Ben]

am i wrong?

Yes

I was trying to help you, if you had posted up what you wnted to do from the start and not been so ****ing arrogant i would of helped like i was trying to.

[novanova636]

ben i did say what i wanted. i just asked if anyone knows how much to skim off my head. you come back straight away with dont do it yourself give it to someone else. so thanks for your help.

[Ben]

Well you didnt explin very well, the normal idea of someone on hear skimming there head is with a plane or grinding wheel. And yes they do try it!

lmao i have seen accutly someone try to do there head on a grinding wheel lol

[novanova636]

ok so its a missunderstandin. im new on here i dont wana piss ppl off i just needed a lil advice.

and really a grinding wheel?

[Ben]

To be honest going back to the topic in general, I personally think you can improve the performance easily enough without having to go down the skimming route, its a lot of hassle for small gains and chance of ****ing up etc, do a search for Stu's blown 1.2 guide for more details as he went right into it.

[Ben]

try here its his mini site...

[Ben]

ah couldnt find it.

[turbojolt]

haha i win lol


also steer well clear of the 1.3 crank and rods mod as you will have a mega hard time finding them im starting to believe they were never made

[garyc]

you can easily take a good mm off. on the 1300 heads we use for autograss they have 2mm off.

I have 1300 cranks rods for sale, PM me for more info.

[novanova636]

pm'd, cheers for the head skim amount aswell
