7AGE Options

[WH95TE]

Ok, so this seems to be my only option for more power, gettinga 7age, and eventually getting a turbo. I've tried looking around Club 4AG and that place is just a mess and confusing. So with that said, i'd just like to know about this mod.

1. What are my options and what kind of results can I see with them?
2. What exactly would I need to do this?
3. And around how much would it cost?

The last question not being as important because I will probably head to a junkyard to see what I can find.


If there is a post with all this information, just point me to it. Thanks

Anybody? lol...

look for 130-140ish hp

if you want power turbo will get you there the best a 7age n/a is good for is 200 horse or less
frotou has a 7agte but hasnt dynoed it yet i have a 312whp so far this winter it will under go a few more tweaks and changes in order to get the 350 + whp on pump 92 gas

2. What exactly would I need to do this?
check the link below

3. And around how much would it cost?
depends on what your power goal is and parts you use i bought all new execpt my cams were used but in really good condition also if you have the time and knowleage on my build i turned it over to the shop for the most part i did the research and some of the build but head work and boring they did and a few custom peices but labor alone on mine cost $5000 alone and parts where $8-$9000 . dont let that scare you i went all out you can build a 7age or 7agte in your garage which im doing right now on a budget


7AGE in a celica is different than a 7age in a corolla or mr2

mid tune on 92 pump gas 312whp and 306 torque fully built but on a mid size turbo i want a good all around turbo that would take to 6 grand to spool and put out 500whp i wanted good mid and high but not have bad low end
7agte

also http://te51levin.superjamie.net/ has alot of good info for the n/a 7age

[WH95TE]

So once I turbo I can look to have around 300hp or close to? My power goal for now is really just to break into the 200 range. Also, i;m not planning no doing this in my garage, cause well I dont have a garage(townhouse) My dad's friend has his own shop so i'm going to get him to do everything, while I assist and learn. Since he's a mechanic and has done work with engines before, do you think he would know what parts are needed just by showing him what I want to do?

you have to remember im fully built stage 2 port and polish 272 cams etc

on a basic 7agte build doing pistons and slapping a head on i would guess 230whp +

i had to go through alot of trail and error making this set up 7agte is complex build and i dont know what kind of experence your friend has with import motors i switched head gaskets 2 times timing belts a few times to get the right set up plus alot of little things that i didnt write down on here that not many people know about the 7agte

[WH95TE]

Well right now hes working on an Eclipse and an 89 Supra. And 230whp+ is perfectly fine lol. Like I said, my current goal is to just break into the 200s

well when i just put a turbo kit together and on my plain stock 7afe i got 170 whp and 180 whp on a really simple tune and a few parts check my 7afte how to

also doggy got a little over 200 on his 7afte with a bigger turbo

[hurley97]

but whats the difference in terms of reliability between the 7AFTE and 7AGTE?

(i am also weighing my options and thinking of going with the 7AGTE)

I think its the head design. The GE head can withstand the boost more because of the better airflow?

Anyways their both Toyota Engine.. they should be very reliable.. wait nvm.. turbo + reliable = $$$$

[Kwanza26]

The reason for a headswap has nothing to do with reliablilty... although you could argue the 4AG head being a performance oriented head can cause a slightly heavier driver's foot... which can hurt long-term reliability... but strictly speaking... the heads (4AGE vs 7AFE) are put together pretty much the same and work pretty much the same (mechanically).

The reason for the headswap... power curve. The 4AG head can potentially stretch the powerband deeper and longer through the revs, as opposed to the 7AFE which maximizes its possible output, even force-fed, pretty quick, but can generate more low-end grunt for this same reason. Its a matter of taste in the longrun, because the FE head can take boost well and does respond very well, especially with torque... but when racing... I mean really racing... you're not gonna be at 4000 rpms very much...

[WH95TE]

You can get better numbers out of the 4AGE heads compared to a 7AFTE though, right?

depends on the boost and where in the rpm we're looking at.

Assuming both are of the same turbo configuration and boost... the 7AFTE will make more torque around 2500-4500 rpms... but not as much horsepower overall because of its inability to flow as the revs speed up. The 7AGTE won't make as much peak torque, but typically speaking, will peak deeper in the rpm band (4500 rpms +) than the 7AFTE and will make more power because it can flow more, deeper into the rpm band. All this does is make for different types of engines. Consider the 7AFTE a better suited engine for drag racing because of it's larger torque (which isn't actually that great for FWD cars... hehe)... and the 7AGTE would be a better engine for track racing because of its more efficient use of available power.

[WH95TE]

I see, so maybe i'll just turbo my 7afe then. People have gotten in the 200hp range with a 7afte right? That's really all I want.

[hurley97]

i like the "efficient use of available power" thing. thanks

ive heard a lot of people blow their 7AFTE's and have a lot of problems with it. would the same type of problems occur with the 7AGTE? i just assumed GE heads could take the boost better.

Thats what I thought Hurley.

[sinner96ST]

People who blow up 7afte's usually are running junk setups. The only person who is an exception to this would be OOBE, who had pre-existing engine problems before he turbo'd, and wound up frying a piston or something like that.

99% of the time people have to go 'custom' because the 7AFE isn't really a popular tuning platform. The GT's 5SFE is different because a lot of 3sgte parts are interchangeable with it, so pretty much all the work is done for you from the get go.

You can turbo whatever you want, as long as you don't cut any corners. Expect to pay at least $1500 to get it running decent, and that won't include any tuning you need to do. If you're still hungry for power after you start boosting, do what Nik did and go all out with the hybrid, but don't expect it to be a cheap or quick solution.

As far as reliability goes - it's Toyota, the name is synomymous with reliability.

[Culpable04]

so the 7AFE can be turboed with stock internals ? , I mean STOCK. what would be the maximiun pressure we can put in it without issues ?

no more than 8psi is recommended, and even at 8, all precautions should be taken outside of the engine to prevent detonation. intercooler, proper tuning, colder plugs, retarded timing, all that jazz.

it's not really a performance engine, so force feeding it puts more stress on stuff.

hence the reason for swapping in the more performance oriented GE heads. no?
