hi all i have hi comp venolia forged pistons,rollmaster timing set,stainless steel valves,arp bolts, lightweight flywheel,exedy clutch,twin 45mm dellortos

i have been collecting these parts for a while and was always planning on using a15 engine but now am having second thoughts

so i thought i would get a second opinion

which motor do you guys think i should use and why?

The answer is simple

"There is no replacement for displacement"

Go the A15

Quote:

Yes there is it called knowing how to build an engine right.

What will be the application of the engine thats the first thing ?

yes what is it used for?
An A15 has more displacement, and also a lower max rpm. So if you don't mind going to 9000 rpm, an A14 makes a little more HP, but the A15 makes a little more torque.

What if both engines were built right? doesnt the old axiom of "There is no replacement for displacement" still hold true?

'theres no substitute for cubic inches'

but revs are sweet..

depends what you want to do with the engine,

it will be much of a muchness..

it is for road use (my ute )

A14 = revs/topend hp, A15 = torque/burnouts .........

spend enough on either and get it built right and you wont be dissappointed

the difference is little. i use a A15 cause i weigh over 100kg so i thought the torque would help lol!

Quote:

like your way of putting it.. i'd go the a14 as much as i like a burnout.. having a higher "redline" is somewhat more satisfactory.. being able to say "my car revs to 9k" beats 3gear cooks. maybe...
