4ag SC14

[GZE016]

I've searched and i think i've found enough info to fit a SC14 to my 4ag but i have a few questions so hoping someone can help or point me in the right direction.

I'm planning to use the SC12 pulley and standard crank pulley, how much boost can i expect, rough estimate on power at wheels and how will the standard AE101 computer cope?

Thanks
Vic.

Computer will be fine. All you are doing is upping the boost a little.

You can estimate boost using the old chestnut (assuming same pulleys):
New boost psi = ( (old boost psi + 14.7) * (1.4/1.2) ) - 14.7

Since SC14 pumps 1.4L per rev, SC12 pumps 1.2

There's a thread on ae86driving club with a few photos of different setups. Main problem is the SC14 usually mounts on the passenger side of the engine, so the mounting tabs are on the wrong side. Making mounts is slightly annoying given that.

Thanks.

Any idea of power output?

SC12ed 4AGZEs make anywhere from 90rwkw to 120rwkw

I'd say SC14ed ones would make from 105 to 140rwkw at a stretch. But then it all depends on what else has been done and which dyno figures you believe.

Best estimate is to add 10-15% to your current SC12 power.

There is also at least one on Toyspeed.

It makes 85kw at front wheels and i'm hoping for about 100.

Would it be worth fitting 3SGE throttle body or NA manifold while i'm at it?

That is a YES.

Thanks, TB is the way to go.
