but i have this mate who works at autobarn who has a 4age aswell his got cams $800, chipped $700, Air induction, under the air box theres a pipe that goes down under the inner gaurd nice for cold air  , his has alot more boot than mine standard, his at autobarn bundall on the goldcoast if u live up here he'll help you out or maybe send them a email and his name is steve never know he might reply.

Well unless you go to the trouble of fabricating a totally isolated enclosure for it with a cold air feed, it will be sucking in hot air constantly and he worse than a good flowing filter in the factory airbox.

yep callmefrank has it correct, hot air = bad, plus we have to many air sensors and vacume hoses so its alot faster-better-fuel economy to leave it standard, plus its about $100 for a piping that will fit all the sensors and you dont really gain alot.
people say you gain 5kw or so from a pod but really you dont, to make something work you need everything
-exhaust
-air filter (i have a KNN panel)
-platnum sparkies
-air induction
and so on...
me filter was $130 and its good, didnt make a speed difference but makes oil cleaner, air cleaner, prevents water adn dirt etc from getting into the engine. now wouldnt that be better than an amaginary 5kw??

A friend of mine from portugal is running a 20v throttle, motech, ze injectors, 288 toda cams, Custom pistons, twin injection, 5th injector to the throttle, light flywheel, shaved head(10to1 and high flowed),custom springs,Custom Cranck, improved combustion efficiency.
Tuned for 10.000 RPM redline. Just recently he crunched is second t50 so hes getting trd close ration gears.
Very fast engine for an NA

ok I have had on my AE86
Port and polish: performance gain isnt much, but the difference in exhaust note more than makes up for the price is cost me.
Pod: fuck all, same with airbox and cold air ducting. Note, my car never had an airbox to begin with.
Extractors: going against what everybody says, they made a pretty nice difference to power. I think the main reason for this is that my original manifold had some really dodgy bends connecting it to the rest of exhaust. I also like the sound of them (4-2-1's) alot nicer than 4-1's I have heard.
Cams: HKS 256 degree in and exhaust, I'll Tell you later today

256 degree cams are definetely a good thing.
Idles not perfect, but the noise and midrange response is a nice improvement.

since changeing the extractors dont do anything, ive been told it is beneficial to lengthen the pipe between teh extractors to the catalytic converter? is this true?
what exhausts system is the best for a mildly worked 4age. id say2inch is fine, but 2.25 might do just that little more. however i dont feel the excessive noise is worth it.

Both my mk1 MR2 AW11 s are standard apart from the ECU.
I reverse engineered the 4AGE ECU.
See www.jmross.freeserve.co.uk/page1.html
for my diagnostics/datalogging interface for this ECU.
I also made a reprog ROM board for this ECU that supports the original factory ROM.
I have had a lot of fun doing this. I am now looking at the 42pin micro used in the MR2 SC and the 64 pin micro used in the mk2 MR2 ECU and the Supra Turbo ECU.
I aam hoping to fit a better exhaust and air induction kit and mild cams soon.

Jeremy

No. About 185hp at the flywheel. To get 185hp at the wheels with a 1.6 4A-GE, you would probably need to rev it beyond 11000rpm.
With a N/A engine, you only need to know the capacity and peak RPM and you can have a very good guess at what power its makes at the flywheel.
Anything over 100hp per liter is very good for a engine that revs to less than 9000rpm, but not too hard to get with 16valve and big cams.

Mainly just smoothing off all the sharp edges in the inlet and outlet of the pump to make it flow a little better.
Same with the oil drains, with a tiny little belt sander that I have at home. I removed all the casting flashes & smoothed off the sharp edges to let the oil return more effectively.

Interesting Bill, now im curious to see what mine will be making.
304*/8.5mm cams
Solid Shim/Bucket (1SZ)
Adjustable camgears
Port/Polished Head
4-1 Extractors (almost as cheap as a cast mani for me)
3.4kg Alloy Flywheel
Haltech E6X
4AGZE injectors
All in all its pretty odd how two totally differently designed cars can end up being pretty similar. Simply because of a shared engine bay.

Should be up around the 180hp mark if everything's right.
You'll know, because it'll be hard to drive in the wet.

sorry fo digging up an oldie but i thought it was better than asking the same shit thats probably been asked a lot.
to do similar mods to any 4AGE how much would all that cost as im building up a track car and want similar stuff done to mine.

inark: Give you a run down of cost:
Port and Polish was around the $200 mark.
While the head is off get the valve clearances set for the higher lift cams, also get the head freshened up.
Total would probably be around the $500 mark.
My cams were expensive as they are new HKS ones. Cost me $900, but you could get cheaper ones through Wade cams, I just didnt have the time to wait for local stuff. I think these are around $500 a pair.
For extractors Anthony Kellams(sp?) ones are quite cheap. I think they are around $300?
You will need a new VRS kit to fit the head back up, plus maybe some new water outlets etc, so factor in another $200.
So all those mods would probably cost you about $1500.
My engine is coming apart at the moment and am probably giving the bottom end a freshen up with some High comp pistons. I also have some adjustable cam gears to fit.

double it comes to mind! forget motec if your on a tight budget.think microtech etc and new quad throttle setup is going to be a lot more than $600 if you want that maybe your better of with a 20v.

Top speed in a particular gear means SFA what it usually means is you have a fairly low ratio diff being a stock corolla,
my sprinter rally car would be lucky to be be doing 110 in 3rd but i bet it gets to 110 twice as fast as your corolla. Thanks to a 5.1 ratio diff and close ratio gearbox.
terminal speed is no good if it takes you longer to get there IMHO.
FWIW even for a cheap ECU, budget $2000 for ECU, install and tune.

5.1 eh. How do you find it. Im thinking about a 4.5 or a 4.7 at the moment. Although i think ill be getting to higher speeds than you on the straightaways rather than dirt roads.

I wouldnt go any higher then 4.7 on track, we topped out at about 170/180 down Mount Panorama so you might need some more legs, check what ratio Terry runs.

|
Wiseco pistons (not sure of c/r), lightened/balanced bottom end, cams (don't know the specs), adjustable cam gears, porting, bored out throttle bodies, bigger injectors, wedgeplate, modded oil pump, tuned length 4-1s, ext electric oil pump to cooler (leaves the int oil pump to lubricate the engine, but only cools the sump oil), Motec. It's running a fairly conservative tune atm, we didnt have a reliable way of detecting detonation on the dyno, so we increased the ign trim - made more power, increased the trim again - made more power again, so backed it back to the 1st setting. Its safe, but i'm sure there's more in it. Once I get my hands on some decent knock sensing gear, we'll go again and get a bit more aggressive with it. Its currently redlined at 8200rpm for the sake of longevity, and it's power curve was pretty much a straight line up to the soft cut, no holes or dips.
To put it all in perspective, My S15 pushed out the same rwkw figure on the same dyno with it's boost restrictor removed (additional 1.5psi) - its rated at 147kw (at the fly) from the factory, and it weighs 250kg more than the KE35 that my 4AG is in...
