Building a 16v turbo what parts

weather you move the piston away from the head or the head away
from the piston surly both have the same side effect of killed squish?

forged pistons are overkill for some people, but i think on 16v they
would be a part of my basic setup

 

Stacked headgaskets,i would worry more about them blowing than squish.

I would think any pistons with different dish etc would change the squish and even gasflowed heads would too,so what ever you do to lower the CR,squish would change for the better? or worse?

 

dont have to stack gaskets to space the head from the block, thick
copper one would do the trick. To be honest if i were building a
turbo'd 16v i wouldnt be happy settling for ofset bushing/ thick
gaskets etc etc etc not when nice pistons are so cheap

Where from?? how much would a set cost with rings for my 2lt 16v.

I was told a thicker copper headgasket wasn't the best and safest way for longterm engine reliability.

I know the yanks love them and find them reliable,but they do like stripping their engines down quite often so.....

 

not in all the time i have been using them. and not when fitted properly

 

brahn bremner give 2 options on their supercharger kit spacer or pistons

 

Ahhhhhh. Cheers. What the ABF lump from again?

 

Mk3 2.0 16V

 

Ahhhh, sorry. Ws thinking of the 2.0 "2E" block. Durrrr. Am I right in thinking the breather for the 2E unit is in the head, and the breather for the KR unit is in the block. So, on a slightly different subject, when you run a KR head on a 2E block how do you get around the breather issue?

 

use the 8v oil cap with the breather in ??? dunno haven't got any 8v motors so just a guess

 

Use a block-off plate on the KR breather hole, and use the 8v breather.

 

Sorry, this is probably me being stupid.... I'm planning on using a 2E block and a KR head. Neither of which have a breather when bolted together, so how do I get around it?

 

Don't the 8V block just have a blanking plate over where the breather sits on a KR?? I think so but it's been a while since I played with an 8V block. If so you could bolt on a KR breather.

 

Aaaaah, I was mixed up - Mr Purple is probably right, I don't see any reason why a KR breather wouldn't fit into the blanked off 2E hole.

 

Sweet. Cheers fellas.

 

That manifold ended up going for less than 50 as well... another one I should have bid on..........

 

blimey this is a few year old

 

hi folks.

ive been reading this one with interest and was wondering if i could get close to a turbo set up with the bits i've got.

a golf mk2 91 16v with a 2.0 lt ACE/6A engine in it
a 2lt audi engine (2e?)
a mk2 8v gti digi

could i use the audi engine as it has a comp ratio of 8.90:1
instead of the 16vs 10.80:1?

would i need to change conrods?
what stuff other than a turbo would i need?
what turbo could/should i use ?

 

Can i also add, stacked gaskets work fine. I know many people running them, not cheap ones mind, proper upgrade steel jobs with cevalar brute seals.
Toyotec for example can push near 300bhp on them.

You can run a standard compression engine (say a 2.0 2e 8v) upto 12psi if its in good nick.

Its all about the managment, if you have a very sensitive and accurate ignition map, good working high quality gear such as a high voltage low resistance coil, good leads and decent colder running plugs, and a good fuel system with components that can easily match the engines constant fuel requirments without running to close to max duty (ie injectors and max flow ie pumps).... all will be good.


Remember, detonation can be controlled by ignition and quality fuel, overheating and temperature can be controlled by fueling.

Obviously all this is no match for lowering the comp ratio to allow for the turbo to plow a good 20psi in, but im just making a point.



Megasquirt is worth swatting up on cheap managment, gives you full control and lots of great upgrades including boost control, lauhcn control to name but a few.

 

someone said to me that by stacking head gaskets , it puts the timing out at the cam, and the only whay to adjust that back is to get vernier pulley ? ive stacked mine, so it that worth worrying about
