Max a 16v 4AGE can be tuned to?

[panda_tureno86]

love these topics about how to build a 4AG...

The early bigport 4AG can flow the most hp out of all the 4AG heads.
If you are planning to build your blue top.
I would suggest you get yourself a 7 rib block.
Internal of the early model 4AG are not strong.

If you want a cheap way to build a 16V
I would suggest you do following
a silvertop bottome end.
Use it's crank and rod.
Its strong enough to rev up to 9 everyday, providing you look after the motor properly.
if you are tight, then use some small port pistons. They offer a better compression than your big port ones. They are dirt cheap comparing to TODAs or other japanese brands.
You should note that running BIG cams on the 16V meaning you will need some underbuck and shim kit..... which will cost you AN ARM or your kidneys.
I wont even port out the bluetop, just give it a quick polish...
And then run some ITBs off a silver top.
Remember to shave your head and deck your block too to get a better compression, you have at least 7mm of valve clearance.
Doing all that you will be lucky to get 150hp on your crank
(providing your cams are like baby cams)
you will be able to run stock computer that way.



I note that you guys have only 95 octane juice over there......
maybe its worth while running a black top after all.
it would be better off for you for daily use.
and it sounds awsome too

Anyway, good luck.... hope this won't turn into a project with a dead end.
