Just like the title says...

I own a 1997 ae111 toyota corolla, with a 4afe engine, and I was wondering if there where any light mods to do for more umpf... I dont have the opportunity/money/facilites/know how for an engine swap just yet, so I was thinking of a way to get the most of my old engine first.

I was thinking of installing a turbo from a toyota liteace, if that is possible

Toms turbokit would be a viable option.... You can ask the price from the tom's shop in kilton motors. You're from makati or not? Its on the other side of pasong tamo if you're coming from ayala center. Easy way to get there is to go in Sen Gil Puyat avenue and then turn left after pasong tamo, before you go under the skyway.

This was though 4 years ago :p

t would be almost impossible to build a high-performance naturally aspirated 4A/7A-FE.
LOL thats really a bunch of crap.

4A-GE 20V has little aftermarket support anywhere except UK and Japan and few countries with RHD. As for potential, its there, but people are too blind to see it, because they just concentrate on the common modifications.
Quoted from billzillas site:
To back up the estimated power figures of the 4AFE, here's an example. As fate would have it, a friend of mine overseas has built an engine almost identical to what I will be building. It's in an off-road buggy and on an engine dyno it has made 248hp at 9,000rpm.
Thats NA tuning for you doubters. And as far as I know, thats with the 1st gen head.

LOL that's an off-road buggy, not even a car. Hardly comparable to say the least.

Until I see some actual pics and some dynojet plots of such a setup, I will continue to doubt the power potential of the 4A/7AFE. With that said, however, I really do hope you, or someone else here on TN does prove me wrong.

It's very possible. You can go N/A - high compression, port the living crap out of the head, free up the intake, header and exhaust should net close to 150chp.

Or you can get an f style head turbo manifold, fit a turbo with the correct exhaust flange, bolt it on, run your downpipe, run your oil lines, run your intercooler piping, upgrade your injectors, and get a tune from a standalone unit, atleast a piggy back.

N/A power is very responsive, and also very expensive
Boost power is fun, much cheaper, and theres nothing like a turbo spool followed by the wastegate opening - bov sound
