Engine build

[ikklemack]

ok so its too cold to sit in the garage welding so ive decided to start building an engine so ive got a couple of questions before i get started.
full flow case is it really worth it for a budget build?

will these barrels and pistons fit straight to an as21 case

last question how much do you guys think il be looking to pay for a pair of twin port cylinder heads second hand?

AS21 case is made from a tougher alloy and should be ok. Check with Aircooled.
Full flow not worth it for a budget build IMO.
I picked up a couple of heads for £40.

thanks never thought of just asking aircooled :lol:

yes 87mm /1641 will go in.

i would full flow it. apart from some drilling tapping and labor it isnt a great amount of cost (filter head and pipe/fittings cost though) and it adds a load of security in terms of filtration.

i have seen some about lately for about £100 for a pair of heads. strip and rebuild and your away.

hmmm does anyone know where i can find a decent guide for the full flow?

obviously you can do all this when the case is split then wash it out so there is no contaminates any where.

I personally would go straight to 1776. In the grand scheme of things the extra money on machining would be justfied by the extra grunt.

 

[ikklemack]

ive just had a little look into it and it looks like i won't be able to stretch far enough for the machining. i am going to full flow the case it doesn't sound to bad to do.

just out of interest now so what is your spec you are going for then? cam etc.,

 

[ikklemack]

i'm just going for standard really. i'm not to fussed about power just reliability. i only thought about the 1641 pistons because there isn't alot of difference in price to the 1600
