Was faultless at every trackday until I joined the Vx crew for trackdays....

 

So it broke, while trying to keep up with the pace of the vx's huh.....

Not all vxs even broken Kieran was holding me up

The K20 is difficult to improve I hope it all goes well, a friend of mine took a DC5 integra to a local "tuners" and they bolted a load of parts on, rebuilt it with high compression pistons and a big valve head with cams and when he took it to get mapped it produced less power. Honda did a very good job of these engines but forced induction makes everything better

 

 

Do your research well for improving the K20A head... It flows very well in stock form

[The Batman]

Exhaust ports - gasket match and polish Intake - flow the manifold Ports into the gasket and then gasket into the head Then a nice head skin I'm not going for mega power which is why I'm using Honda intake and cams

Only thing that's stopped me doing a trackday was self-inflicted (well, now I think about it, you were responsible for that too). Major league hangover.   

 

 

 

That's funny, I thought it involved peas....

You see, that's just urban legend. What I said was "it's the tea's", the spunk shot filled tea pot and tea cups amongst about 20 bottles of cider was not a good combo. Thank god for the nice stomach settling digestif sambuca shots at the end of the night, gawd knows what state I'd have been in without them.

Tb ported and idle control opened up



Manifold ported to flow into the gasket

Can you smooth all your manifold through? I use a hybrid scotchbrite/ emery flap wheel for these jobs. Later I pull the emery out and just scotchbrite it. Nice and smooth without being polished.

[The Batman]

I will give that a go. In America I have seen them cut the back off to polish it all and then reweld it! I can't raise my cr as much as I wanted due to piston/valves. So will settle with what it's at. Then get a bottom end to build up at a later date when more funds are available!

Inlets



Exhaust

[FLD]

Polish that exhaust side joe!

[vocky]

Polish that exhaust side joe!

 

there is little point, within a few hundred miles it will have a coating of exhaust soot

[FLD]

Yeah but it's shiney so it must do something! 

I've always done it and it does get the coating of soot but I still do it.  Must be a habit.

[The Batman]

Valve pockets machines bigger and head skimmed

[Nev]

Nice casting geometry on that head

[The Batman]

Thanks nev!

Well a nice big air filter turnt up today.. Hopefully won't be too loud on track.. If it is JG owes me money

[FLD]

Looks similar to something I saw at your mums house.

[Aerodynamic]

What intake manifold is it? Br, Per

[The Batman]

It's a Rrc

[haggi961]

Which size filter did you go for mate?
