Ok who has turboed a 7A-FE and what are all the parts that are need, and Mac means all the parts needed to turbo the 7A-FE(sorry about the last part I'm in my WWE Smackdown mood)

well, off of the top of my head

turbo
manifold
intercooler
piping
boost controller
BOV
fuel system upgrades(i have an fmu and im gettin a safc soon, there are other things u can do)
check valve
piping
2.5 inch exhaust
down pipe
boost gauge
AFR gauge
oil line kit
air lines
and if you have a 96+ you will have to modify the distributor mount to allow for timing changes
4 quarts of oil, actually, a little more than that

some nice things to have

turbo timer
egt gauge(some say you need it)
a place to put the gauges(gauge pod)
new fuel pump
new injectors
something to disable the limiter

there are probably some other things but i cant remember them right now.

you definitely need to up the injectors, that's not really optional. if you stay under 5 psi, tho, an intercooler is optional. and you don't have to get an electronic boost controller, you can get a manual one cheap. if you get toys, that ups the price considerably. and you DEF need an EGT gauge. AFR gauges are not necessary at all, they just look cool. i dunno what you mean by "air lines" either. just an oil feed and an oil return.

i'm turboing the 7afe as well, i have all my stuff. i think a necessary part of the project is learning what you need. if i just gave you a list of "buy greddy blah this, and HKS blah that" that defeats the purpose of a "custom" kit. also, if you are like me, and installing it yourself, if you can't research to figure out what you need, then you really shouldn't be attempting the install. good luck, and let me know if i can help you at all.

Yea i'm doing all the work myself if i do chose to go get the turbo. I'm just making a list of all the parts i need. I know the stuff that i need for sure like the injectors...ect.... I just want to make sure i'm not missing anything out of my list.

ok thanks for correcting me

im sorry but by air lines i meant vacuum lines, for the boost gauge and other stuff that needs airpressure from the manifold

oh and charlie, what would you say is an ideal EG temp? i know that on the jgs website it said that they ran 1600 when tunning(which implies that it is really really high)

what you may also want to look at is the cooling system.

If possible, get an oil cooler and make sure that your engine cooling system is running efficiently.

Expect to to see and increase in engine temp at ruff/sporty driving.

Aslo, you will nee some t adapter for vacuum hoses and running the oil from the oil filter to the turbo.

If possible, if your Boost controller does not have Fuel control, try looking into an Apexi SAFC.

While you are shopping, pick up a good ACT or some other brandname clutch for the added increase torque.

Looking into a Oil pressure gauge. Monitor oil pressure during runs until running right out.

You may not need to upgrade your fuel system. What you can do is to use an Adjustable Fuel regulator (w/ boost control), check and see if your FP drops in wide open throttle with very light boost to the max boost (which maybe 5-6psi), with your big injectors..

If you notice a drop in fuel pressure to much, you will need a new fuel pump.

I hope this helps

I have a question Charlie!

Any particular reason why he doesn't need an AFR guage?

And if he doesn't, how can you determine proper fuel ratios under rpm&throttle loads.

Look forward to your answer.

oh wait, you are right, i misspoke. you need an AFR gauge if you don't have an AFC. i have a SAFC, which has the afr on it's display. good catch man, my bad.

also, as to an oil cooler, i addressed this in another thread as well... unless you are running crazy high boost, which you can't do on a 7afe, you won't need an oil cooler, and in fact, it can detract from your performance.

well u guys have hav emost of the mods listed. You dont need to up the injectors actually. If u are planning on running more than 11 lbs on it then u defiantely need to. People suggest to up the injectors wen ur duty cylce is higher than 75%. Wen i was boosting 11 lbs my dury cycle was set at around 65-66 % to attain the boost level. Oh and charlie i gots a custom downpipe too if u or anyone else needs one to build their ST project. An EGT is not a must but very helpful. I wish i had one so i could check my exhaust temp cuz its been burning really hot recently. Intake side of the piping is cool but exhaust side is hot... ****ing weird wen most people say the are both supposed to be cool. Well good to u all building ur celicas. If anyone needs a custom exhaust manifold or a turbonetics delta gate please message me. Im looking to sell them.

Hi Turboceli!

I am not a moderator, but this is the sort of threads that are needed.

I wish everyone could thread like this.

I do not know what size injectors the USA celis have. but any upgrade would be helpful.

Charlie, I mention the oil cooler if he is going to be driving fast all the time.

His engine temperature will definately go up. If he cannot keep it cool, the oil cooler would help.

Thanks for all the help guy's I just wanted to make sure i haven't left out anything of the list i have at home. If i do go with the turbo insted of the engine swap i'll let eveyone know.
and keep the info flowing for those that are looking into a turbo for the 7a fe

I have also a 7A-FE, my question is. Is the money,time and effort really worth turbo charging a 7A-FE engine?
Well I guess for some people who can afford to spend money are up for the challenge. I've done a lot of inquiries in the past even people who sells Tom's turbo kit for the enigne are saying its not worth the money compared to buying the whole 3S-GTe engine. Main reason is there's nothing much you can do on the engine.

yes it is true that for not much more you can do a 3sgte swap and have a great engine that is built for performance but that may not be an option for some poeple. some people just want a little more power than what they have and to them an engine swap would be too much of a hassle.

If I had a USA celi, I would upgrade to either a 4AGE or a 4AGE 20v silver/black top.

Why?

1) the 4AGE have a G head optimise for performance.

2) You can get a lot of parts for them!

3) There are alot of 4age forums out there.

4) I have personally be driven in a 4age 20v silver swap with turbo. It was quick but could not compare it to the blacktop w/ turbo.

So my advice to you is to swap in a 4AGE which should be very easy for all 7AFE celi's.

honestly if i could go back in time, i would have gotten the 3s-gte swap instead of turboing the ST. It was really fun to drive and the power was there, but u end up just wanting more. So im going 3sgte in 2 weeks!! =)

see, i want power, but not a lot, so the 7afte. also, i think a custom turbo setup will garner more points than an engine swap, especially with so many people with the 3sgte.

besides, i have a 3sgte that i'm building up for another car right now, not gonna waste that puppy on a FWD car.

Then you're going to turbo my car too right Mac?
