Why is double valve springs being suggested - surely stronger single ones would do?

Even my circa '79 A12 will rev to 8000 on bike carbs and extractors using stock springs - not many street-able cam grinds would need rpm capabilities higher than that surely?!

hi guys im going on the turbo a14 but i want no carbi on it i want to go EFI im after a complete EFI manifold if anyone can help me

thanks

Hi, Have you or a friend got a welder and/or any good at it?
With a weekend and about $50.00 worth of 1 inch ID steam pipe bends you could make a pretty sweet turbo manifold set up for your A14.

Is your turbo fitted with a carbon seal (can it be converted?) if so you could make a very simple draw through turbo setup, I have run a draw through turbo setup on my A15 for 10 years plus (30+psi boost)and found it to be both economical and very reliable.

On the other hand you could go for a blow through setup (if your turbo is not fitted with a carbon seal) however this type of setup is a little more tricky to get setup and get running properly.

A turbo charged A-series is a beautiful thing and make buckets of torque all on standard internals, just don`t rev the piss out of them (6000rpm+)

Somthing to think about anyway.

Cheers,

h89 head double valve springs, mild cam, twin sidies extractors, electric dizzy and all should be fine. Dont need much more then that

yeah mike is able to get a lot of parts through bprojects. they deal with pretty much everything lol

well the problem is that i live in the dominican republic and is not easy to find all the parts

yeah no worries mate. another bloke on here is dundee1000 he is a great help he gets all of my parts for me pretty much.

well thats a lot of help i will go with this setup as soon as i buy the engine il start to update my post thanks popo1200perth

is stick with the a14 head.. just put double valve springs in it a bigger cam and get the carbys to suit the cam you run. headers will make a bit of an improvement aswell and weekend_1000 sells electronic distributors aswell pretty cheaply on here his name is mal

so what head should i use? im want to use a twin carb setup and a racing header
