4age=pwned

[aphxero]

By excessive rpm!??

I managed to break my crankshaft.

I've never heard of a 4age doing this. Anyhow, A new one is already in the works. Maybe in 2 or 3 weeks I'll be back doing my thing.

So does anyone have performance parts for sale? I'm still looking for a set of rods. 20mm wrist pin style.

Thanks,

[Jordan T]

use 20v internals, heard they are superior to the 16v internals. not like you dont now that already.

[Animosity]

uh..i think he has a 20v already, and is doing a full motor build..?

[Jordan T]

no he had a blue top with gixxer itb's. if your talking about a new motor then cool! i dont care too much for 20v head because 5 valves in one combustion chamber does not make it easy for bigger valves. itb's is a fav of mine though. marks the man with the plan, and large amounts of toyota know how. so ill trust what hes doing will be the end all be all of 4ag. or maybe 3sge?

[vertigo_16201]

well its a cast crank

[aphxero]

VeRTigO: You shouldn't make comments if they aren't true. If it was a normal type of crank this wouldn't be so surprising. Remember the 4age is a race engine before it's a production engine.

Maybe you should stick to hondas?

Anyhow, here's a little info from Richard White:

4A-G Crank

The 4A-G crank is by all appearance a high performance piece of hardware. Unlike many production crankshafts which are nodular cast iron, the 4A-G is forged. It is a forged carbon steel, five main bearing, fully counter balanced affair. Each journal is cross drilled for 360-degree supply of oil to the connecting rod bearings, and each hole is chamfered to aid in oil delivery. An additional feature of the 4A-G crank is that each main bearing journal has rolled fillets to improve fatigue strength.



The transition between the main bearing surface and the crank counter weight and rod journal is subjected to very high torsion forces. Compressing the material around the transition, increases the strength and, therefore, the life of the crank. Other performance features include the use of a roller bearing (Toyota p/n 90363-12003) for the transmission pilot shaft (T50 Transmission only) and the use of eight 10mm fly-wheel bolts rather than the usual six that many engines of this size would normally have. This is contrary to Toyota’s illustrations in their own repair manuals typically showing six. And because there are no dowel pins to locate the flywheel position Toyota uses close fitting shoulder bolts. If the flywheel and crankshaft are fitted and torqued properly, all the stress (compression/friction) should be at the interface between the crankshaft and flywheel and the bolt’s shear strength is only needed if something in the system has failed. Rarely do you want a design that uses a fastener in a single shear plane. Bolts are at their best in tension.

Anyhow...

[Jordan T]

well...
what are your plans? 20v or 16v? if it were me id go 20v bottom, red top head with you gixxer set up. im not too sure but i think it would be easyer to place all 20v internals into the reg 4ag blue or red top block. seems that radiator hosing is a pain in the ass for a black or silver top swap. im prob wrong though.

[lunchbox]

holy piss...

[Silvia_San]

mark if you don't do something excessive to that 4ag i'll be very dissapointed. ;)

[Animosity]

im almost positive he will:-D even tho i dont know jack shit about toyotas, i thought he had a 20v before lol? must be someone elses engine im thinking of

anyways, best of luck to building your new engine mark

[mranlet]

Marksaccord = 20v
Mark Castro = 16v

Mark has a non-Toyota radiator, and he could get it to work in whatever orientation is needed.

It's still a daily for him, but neither he nor I will allow him to be one of those "I can't go drift because my car is broken, waa waa waa".

[Jordan T]

hes always had the same 16v blue top. he just got some guy to make a manifold to he could get the gixxers to work. i think the best way to go would be either the 20v internals, or a setup like eagle/weisco. possibly bore over a bit, fully built red top head, ie hks cams, gears, jun over size valves. if the cams are gonna be real nasty with alot of lift, gotta call in some dual spring valve springs. simply retain the same itb setup, or possibly go for somthing with bigger throttle bodys. 20v steup or somthing. the reason for not having the red top block/internals is the heavyer pistons, sure you get more compression with the ae92 engine, but with heavyer (harder to rev) pistons than the blue top, its hardly noticable. really this is my dream motor if i were to get another 86. 20v black/silver top to me is to pricy and not really effective. those engines are nearly maxed out. think about it, 5 valves in a space around 3" inches in diameter, not much to play with. i like 4 valves, leaves room for more options. anyone ever see a 20v motor put out more than 350hp? its a much more responsive motor in factory form, but with a little work to a 16v hybrid, youll be past the level of the 20v still with space left over for more work.

[mranlet]

Every single competitive N2 car uses the 16v. It's no coincidence.

[Jordan T]

ya becuase it is easly modified.

"it is a cast steel and came with a pile of engines I bought from a local impoter that went bust"

http://www.geocities.com/MotorCity/Garage/8422/4age.htm

"The 4AGZE has a cast steel crank..."

I could be wrong, but everything I have read has said the crank is cast

"I can't go drift because my car is broken, waa waa waa".
hey now lol.

[hachibill]

dude, the only 4A to have a cast crank is the 4ac, all the others have a forged steel!! if you need proof then go to toysport.com/tech info. i have taken actual motors apart so i know what i'm talking about. sounds like you just read something on the internet. just remember you can't believe everything you read on the intrweb.

[steve]

how does a crank snap
i mean you put out like 180hp

[lunchbox]

180... hahahahahah yeah right.. more like 110 whp ..he just makes it look like 180 when he drives it!

[aphxero]

I had 110whp. I now have zero. I WILL have ???

My motor has been running on about 5-7psi of oil pressure at idle for the last year. I revved it to 8300 rpm every day. I knew this was coming so I'm not really mad.

Let's just say it won't suck. And it's not an SR that's just rediculous. And to those who know what I'm up to, shut up and keep it secret ;)

At full throttle the new motor should sound like demons being released from hell and out of my ITB. But I don't wanna get ahead of myself haha.

Thanks for the replies.

Oops, let it slip...

your car already scares me, what do you want? me to cry? ;)

[Chin]

hes doing a 2jz with a pt101

[Mars_302]

you're doing a GA16 arent you?

[Jordan T]

seriously doubt all of that. prob sticking with the 4ag. im personally hoping hell retain the 16v head. and i slipped up when i typed that big paragraph. the blue top head is more for high compression than the red, dont know why, but it is. so when you take the red top bottom end and put it on the blue top head, you get the "high comp hybrid". id say that with 20v internals and the gixxer setup would be the shit. or possibly go for somthing larger itb wise. arent gixxers like 35mm or somthing? thats small. and if mark was gonna go with a differant engine entirely, i would predict the 3sge n/a motor. its light and its rated at like 130hp. i think.

[JC86]

i still have my 16v at my house if u need some parts. i need to sell that damn thing.

[mranlet]

GSXR 750 has 46mm throttle bodies (up from 39mm carbs)

[Jordan T]

ohh, i was wrong, i guess i was thinking of another bike. anyway silver/black top itb's are bigger, thats the point i was getting at.

[aphxero]

Blacktop are 45mm.


Stealth, Seriously dude I don't think you're really capable of all this conjecture regarding what I'll do. You need to learn more and teach less.

Anyhow, I've gotta drive around so it looks like I'll be rocking a stock 16v for a few weeks. Doing a different/cooler motor will take some $. Expect "the new shit" to be in less than a month.

[Animosity]

can't wait.

hey bro, look you know all the stuff on toyotas. a lot of people look up to you because of that. why sit there and hack at people? not only are you putting a bad name for yourself but for you company as well. dont be so hot headed man. it was a simple guess.

[mranlet]

*** this is aphxero posting under mranlet's name ***

Stealth: sorry if I came across that way man. I didn't mean anything by it just trying to be secretive about the new project. We've always been cool. I meant no disrespect.

And boosted4ag: your guess wasn't even close haha.

I wanna thank JC813 for coming through with a motor for me to use while I work on "the project".

Here's the stocker we put in yesterday. Well, stock with a little bling haha.

is that vangs parts car 16v? anyway lookin good for now. seeing as how crazy you are, i couldn't even guess as to what's going in there next lol.

[mranlet]

Nah, Vang's motor wasn't destined for Mark's car. That's JC813's longblock with Mark's ITBs, Header, MSEFI, etc.

Here is a hint on the new motor: The more you read the more you know, the more you know the farther you'll go!

[satanshatch]

uh..i think he has a 20v already, and is doing a full motor build..?


Suggest you do not use a stock head this go round.. glad to hear all is well.

[aphxero]

Stock head? For which engine?

And for the record, my old head is 100% fine :)

[Animosity]

nono, i didnt mean he had a 20v to build, i THOUGHT he had one in there cause i never looked at his motor

[Matt Vassallo]

you can cram your 20v up your ass. 16v is king. hasselgren, what.

and it still put down like what? 130 whp ?:lol::lol:

sucks mark

i know the new one will be great

video of curb-hop initiation please ;)

[Ronald Mcdonald]

saw marks car today, sounded great and shitty at the same time....poor poor rolla. haha. cant wait to hear the new motor ;) oh yeah man, that white hatch i was talking to you about, i am going to be buying it. ( i was with the guy with the red sil-eighty trading for the sr coupe )
