I have a spare cylinder head from my other ka24de, its separated from the block which i do not have anymore. im going to turbo my 240 soon but i wanted to ask what suggestions i could do with my spare head? if i port and polish it wouldnt i have to do that to the block too? help me out thanks.

 

What on the block would you port? The water and oil ports? No you do not need to "port and polish" your block. When you have a head portED and and polishED they expand and clean up the ports above the valves for increased flow.

 

what about the bigger pistons if I decide to do that?

 

if you get larger pistons then you will need to do bottom end work, head work is not required although its nice

 

see so i do have to bore it out on the block right? what could i do to the head without touching the block for turbo?

 

Look at my post, You CAN have it ported and polished with out touching the block.

 

ok im getting it but still confused. if i port the head wont the block need to be done too? bigger pistons...

 

no, the headwork is totally different from the block work. You can have either one, don't need both done to work.

 

so will it be better that i do head work?

 

yeah, it will definately be better than the stock head.

Get the headwork on the spare head, when its done rip off the old head and replace with the new worked head.

 

what do you guys think i should do to the head then besides port n polish. how big to port?

 

you would probably be better off talking to the machine shop and seeing what is in your price range and what they offer for that.

 

hrt is like 20 mins away from me here. pricing dosent look too bad on handcraftedracing.com. i think like
Valve Job (3 Angle)
2 Valves/Cylinder
4 Cylinders $90
6 Cylinders $130
3 Valves/Cylinder
4 Cylinders $130
6 Cylinders $190
4 Valves/Cylinder
4 Cylinders $170
6 Cylinders $250

Stage One Port and Polish
2 Valves/Cylinder
4 Cylinders $70
6 Cylinders $105
3 Valves/Cylinder
4 Cylinders $105
6 Cylinders $160
4 Valves/Cylinder
4 Cylinders $140
6 Cylinders $210

What do they mean 2valves/cylinder then 3 valves/cylinder. wont i wanna do all of them?

 

it means how many valves there are per cylinder, the KA24DE has 16 valves, two exhaust and two intake for each cylinder, so thats 4 valves/cylinder, so according to that chart:

3 Angle valve job- $170
Stage one P&P-$140

 

o ok thats wut i figured but why would they just get a few done rather that the whole thing? what you think about those prices? should i do both of those?
