Turbo 4AGE (now with 50% more porn!)
 

Well someone on www.dorikaze.net told me i should check this site out and let me just say its going to be the biggest help of all. Ive only done some quick browsing, but it looks like all my unanswered questions will be figured out after i spend some time digging around.
Anyway now for the business end, i own an 1985 Toyota Corolla GTS (AE86) if you dont know they came with a twin cam fuel injected 1.6L engine. The guy i bought the car from had rebuilt the engine, ported and shaved the head and decked the block. I put cams in it, a header and built a crap 2.5 inch exhaust for it.
But of course thats not enough, so id been eyeing up cheap ebay turbo kits and lucked out with one that was actually in town for $700. It came with almost everything i am going to need t3/t4 turbo, external wastegate, BOV, manual boost controller, fuel pressure regulator, intercooler, piping and hopefully all the nuts bolts hoses and gaskets ill need to finish it off. The kit was meant for a Honda, but all i really need to build is the manifold. Which as you'll see is a hacked piece of work. If i havent mentioned i have no clue what im doing and am fully expecting something to explode or fall off when i first mash the pedal. Im planning on using stock electronics and fuel system, but dont know if thats going to work yet. Hopefully it will be ZC since im only planning on running 4 - 7lbs of boost. This is also only a temporary setup and learning experience. Im trying to get this done for the 14th of December, which is the next drift practice at the local track. I will be getting a 4AGZE bottom end (MR2 supercharged engine forged internals, oil squirters strong block etc), better manifold and some sort of stand alone setup once i have more money and i blow this one up.

Well ill stop talking now and show the few crappy pictures i have.

This is most of the kit, but i think a few things are left out.

This is the start of the manifold, a friend of mine who works at a heavy duty shop was a bit drunk when i told him i was putting a turbo oon my car. He then volunteered to make a manifold right then and there, so we went to the shop and he grabbed a bunch of cast steel plumbing tees and 90's. This is what happened. Me and my buddy Ben made the extension and turbo flange. Its nt done yet, still needs a place for the waste gate and the 2 end mounting holes.

Even though this picture is just the turbo placed under the hood, its going to sit too high, so Ill probably be smashin the hood or cutting a hole in it. And yes i know the turbo is too big for this thing haha.

Comments, advice, laughter, insults. I take what i can get.
Thanks for looking.

Re: Turbo 4AGE
 

what sort of standalone??

Re: Turbo 4AGE
 

No clue yet, ive heard too many bad things about megadquirt and a friend is using a power fc? in his skyline and seems to like it. Other then that I dont really know to much in the stand alone department. Im apprenticing as a mechanic, but electronics are still not quite 100% in my knowledge range. Im trying to learn as much as a can, so ill be prepared. I dont like the idea of spend thousands of dollars to get a tuning shop to do it for me.
I didnt mention in my original post, but i have an innovate motor sports wideband o2 air/fuel gauge im going to be hooking up just incase i run lean on the stock fuel system. Should be a good start for learning i figure.

Re: Turbo 4AGE
 

MAP ECU2 or AEM EMS. There is nothing else id spend my money on. You need timing control, and piggybacking the stock ecu is asking for failure. See this thread if you havent already.

Re: Turbo 4AGE
 

don't cut the hood, just shorten the manifold and re-weld the flange ;)

PSS: that turbo will die, dont count it on liam.

Re: Turbo 4AGE
 

Sorry guys, my turbo headder has tig welds and is polished stainless, I'm an outcast >:D One of these days, I'll get pics, been busy, its dark when I leave for work, then dark when I get home, weekends are usually spent cutting and splitting firewood. Trying to save some money heating the joint. I need to move back to the space coast in FL.

Site I came across for Flanges and things. Maybe you can find it as useful as I did.

Re: Turbo 4AGE
 

Weir sold me my 4age flanges, hes on here in vendors.

Re: Turbo 4AGE
 

I'm using them for some special v-bands for my powerstroke turbo. not too cheap, but high quality

Re: Turbo 4AGE
 

Ahh theres the man who suggested i come here, TTC himself. Whats this porn you speak of. You mean like man on man? Dont forget i have giant pink decals and rims on my car so im on team sausage. Ohh and dont even mention this on DK, everyone there is so ------ negative all id have is people saying im an idiot. Ill post pictures when im done and it works so no one can say ---- haha.
Anyway I was told by 2 other people who used this turbo that they would give me money and or beer if it lasted more then 2000km so i dont expect much. As for cutting the hood im still thinking about it, but since the distributor and brake master are 2 things that are not movable i had to have the turbo sit higher up. If anything i want to move the turbo forward since the down pipe is now going to be tricky.

Thanks for the link Hitchhikkr, im going to read it in full when i have more time.

As for fancy exhaust and flanges its an awesome site, but WAY out of my league. Its not that i dont like doing a nice job, but i have access to a full shop and prefer to do everything myself since im a ------ cheap ass.

And thanks to everyone else who didnt shut me down, appreciate it.

Here are some pictures of the manifold and turbo bolted to the block. You can see how little room there is to work with, ive seen worse, but its still a pain in the ass. The intake side of the turbo points right at the end of the master cylinder, so im going to move the lines and drill the spot welds on the old power steering bracket, should give me enough room. As for the wastegate mounting im going to try and get that done tomorrow. I cant even explain my idea really, but its going to sit under the distributor.

I was lucky enough that the AFM harness was long enough once i pulled it apart that it reaches no problem.

Re: Turbo 4AGE
 

If you use megasquirt, you can ditch the AFM .

Re: Turbo 4AGE
 

I would rotate housing so that it aims down. Easy for the charge pipes.

Re: Turbo 4AGE
 

The old 16V, I miss the poor distributor placement for a turbo setup. The headder I have I assume was made for a 16V, the pipes are moved away from where the distributor was.

Re: Turbo 4AGE
 

Im too cheap to get megasquirt, im going to TRY key word here and use stock everything and run 4lbs. I honestly think its going to work, but hey what the hell do i know. The way i look at it is i cant run more then 6lbs of boost even if i had a standalone. Ill blow the head off since a rough guess of compression ratio is at least 10.5:1 with stock internals. If it doesnt work it looks like ill have to do everything properly.
As for rotating the housing thats a brilliant idea. I was thinking of moving the center section so the oil line was pointing a little less vertical, but i never though of moving the intake. I think you may have just solved my intake pipe clearance issue. Thanks for the advice.
One day when i get my ---- straight i will probably be using a coil on plug setup or the waste spark system from the 5sfe? Anyway for now everything seems to be clearing everything and hopefully i wont melt the distributor cap off or my master cylinder. I am going to get heat shields for both. Im not THAT cheap.

Re: Turbo 4AGE
 

I hate to say it but you could always run FMU
and even viginas run 6 psi.
I want your car

Re: Turbo 4AGE
 

FMU as in a fuel control setup only? Ive thought of that and a buddy of mine even said i could try his APEXI neo, but for now im going to be stubborn.
As for wanting my car, trust me you dont you havent seen the whole thing. Unless you like pink. That and i have more money into the car then what it was worth new, although that aint sayin much.

Heres a few pictures.

Right after i lowered it on T3 gear (www.technotoytuning.com) front weld on coil over kit on the front, NCRCA's, camber plates and lowering springs and AGX adjustable shocks. I now have their lower control arms, tension rods and just did a manual rack conversion. Can you say angle?

Now you know.

Re: Turbo 4AGE
 

Liam, you can clock the housing without moving the centre secition and ------ aroudn with its angle. IF u get MSquirt, you can go edis and do away with the dizzy altogether. Really frees up alot of room. When you put the drain on the pan, make sure its as high as you can humanly get it. That turbo will die, and the tow will cost more than getting a proper one.

Re: Turbo 4AGE
 

Holy shifter batman!

Re: Turbo 4AGE
 

Haha the shifter extension is a lot nicer with my short throw, with the stock shifter it almost hit the dash in 1st and in reverse it was in the passanger seat.

Ive seen the mega squirt EDIS combo before, ive heard its over complicated and hard to tune, but thats only what ive HEARD. No facts to back it up.
As for the drain you're obviously talking about the oil return for the turbo? I will definitely note that since i didnt really know where to put it other then it goes on the oil pan haha.
I usually run my engine at least a half a liter over full since im always going into corners hard and keeping it pinned at the redline. As anyone who has driven a 4AGE hard knows the stupid oil returns in the head are all on the exhaust side and the PCV breather is on the intake. First time i sucked oil through it i thought my engine blew up haha. I almost cryed!

Re: Turbo 4AGE
 

ahh man you shoulda kept the paint orig if you weren't going to get a really paint job.

and the gts sticker on the side is killing it.

i love the car anyways tho.

here's mine, or how it was before i started to tear it down again for resto.

https://www.homemadeturbo.com/forum/...?topic=19506.0

Re: Turbo 4AGE
 

No. Why even bother turbocharging then? After you've replaced a few motors because you blew them up at 4psi, then you will realize why you need a standalone.

You have been lied to. Static compression ratio has exactly nothing to do with the pressure you feed the engine. The airflow of the compressor however, does.
You will blow a stock headgasket with anything that resembles boost with the stock cyl head torque, keep that in mind.

Re: Turbo 4AGE
 

What in the ---- is up with old toyota guys driving nutty ass cars? You all make me feel unspecial, but I'm glad there's other real ----------ers out there. :y

Re: Turbo 4AGE
 

A buddy of mine has run a stock tired bluetop at 7psi ass raping the ------ ---- out of it and it hasn t blown up. Their is nothing overcomplicated about welding a trigger wheel and making a mount. Edis fantastic, you can lose tha tstupid dizzy making turbo fabrication much much simpler. Your going to go through all that work just to blow it up ... Get a standalone and a new turbo, you're cutting the wrong corners... Thats pretty bad considering HMTs standards.

Re: Turbo 4AGE
 

I think Megasquirt is about the cheapest, simplest, reliable EMS out there. I've been looking to possibly get a MS for the wife's 72 mustang when I put the 8-71 on the 408 cleveland.

Re: Turbo 4AGE
 

Well originally this was going to be a $500 joke, then i thought id attempt to do it right on absolutely zero budget. What im trying to say is i spent everything on the kit, now i have my car apart and want to go out to an event on the 14th of December.
As you can see im an idiot to think i could even get the car to fire up let alone make boost without having something go boom.
I came on this site because i was told people here knew there stuff and im sure as hell glad i did. After reading through the 20v silvertop thread quickly i will now be doing it properly even if it takes me, well forever. You definitely sound like you have some experience to back up your facts.
My original plan was to back the timing way off and go from there, hope the stock fuel system could feed the engine enough fuel without flooding at idle and pray that all the stock internals would not melt. I had nothing but crazy ideas in my head and like normal i started ripping and tearing everything apart before i had a clue what was going on.

You mentioned AEM EMS and MAP ECU2 were what you would suggest for a standalone. The AEM system seems a little out of my league and very expensive, like upwards of $2000. The MAP ECU2 however seems like its closer to my price range. Honestly I have very little understanding of standalone systems, which is my biggest obstacle. I dont mind learning, but my brain hurts just thinking about it. I searched a bunch on the net, but i still have so many questions about these systems. Im not going to waste all your time answering questions i may not even need the answer too.
Thanks for all your help, i guess im going to have to figure out what i want to do now.

As for megasquirt and Fords EDIS thats another option im going to look at since it seems like its been proven effective before. I just dont know if i could put Ford parts on my Corolla haha.

The paint job was done for less then $400 by my buddies dad in a tent on their side yard. It turned out like crap, but i was more concerned about getting the rust hole on the passenger side rear fender/quarter repaired and a few other dents dings and small rust holes fixed. Also my horrible sunroof patch job needed about 3 quarts of long and strong to smooth out. Pink stickers WERE NOT ME, I REPEAT NOT ME. Thats what happens when you trust a friend to help you with your car haha.

Re: Turbo 4AGE
 

The AEM and MAPECU are the best ways to go, but you dont seem like your reaching for 400+hp like Conceptz is, you can get away with megasquirt without fail.

Re: Turbo 4AGE
 

You could assemble it and remove the wstegate spring and just run no boost for now. Nothing like trying to make a deadline.

Re: Turbo 4AGE
 

Ya HP numbers arent in my goals list, a reliable DAILY driver that i can take out to the track is. I have a 1990 Dodge Dakota which is my reliable vehicle, but i still think if you wouldnt drive it daily its not reliable enough to be on the track. Kinda weird i guess, but it makes sense to me. Hell my biggest goal is for the thing to run and drive under its own power when i done haha.
As for removing the wastegate spring, ill see if i can even get the car done for the 14th. On tuesday i woke up with a real nice fever and headache. Its getting better, but im not sure if ill be good to go for the weekend.

Thanks again to everyone whos put in their two cents, i appreciate it.

Re: Turbo 4AGE
 

Reliability is relative. I used to work on APBA Offshore Race Boats and some of our engines had a service life of 12 hours. Our Stock Race engines had to be freshened up after 50. My Wife's car is a weekend warrior and built for the track. Then there are what you call Purpose Built cars, Those see little or NO street time, some get towed to and from the lane at the track. on those cars, the only reliability they need is one pass at a time.

Re: Turbo 4AGE
 

Sounds like a good idea on paper, but an unloaded, free-spinning turbo is a dead turbo. It wont last long.

Re: Turbo 4AGE
 

Ok, I learned something today, I figured you could let the exhaust gas bypass the turbine, as long as the intake was plumbed in. What happens exactly? Carbon buildup or something?

Re: Turbo 4AGE
 

I got a little more done yesterday and today. Took a few pictures with everything mocked up again, this is roughly what it will look like with everything done. As it sits right now i have no fitment issues with everything in place, so ill start actually putting things together once I get the manifold surface smooth.
Now before anyone says anything about where the wastegate is i know i may have boost creep issues. I made the extension because i thought i was going to have fitment issues, so if i do run into a problem ill change it. That and no one explained boost creep too me until I showed them the manifold.
Ohh and thanks to Gold DA9 for telling me about moving the housing. Saved me a bunch of work, with it pointed roughly down its going to make pipe routing so much easier.

Re: Turbo 4AGE
 

I have a high flow AFM on ebay right now that will help you a little.

is that a dual cone filter? I had one where the center chrome disc came loose and jammed up in the throttle body. Scared the piss out of me when it stuck the throttle open going down a long steep hill with the engine revving at 4500


Any bets on how long his turbo lives?

Re: Turbo 4AGE
 

Haha that air filter came with the car and ive cleaned it waaayy to many times. I HATE buying ---- off the internet and cant get proper filter in town, so ive been running it for now. Not sure if its a dual cone filter, but ive had no issues with it.
As for my turbo, im going to say 1000km. I honestly dont know turbos and have no clue what is right for my application. Right now i just want to get it done so i can see how this is going to work. I have a buddy with a full megasquirt setup i may be getting for one hell of a good deal. If that goes as planned ill use this turbo for a bit then source a better one. I figured since im running low boost the turbo shouldnt have to work that hard and give me no issues long enough to sort the bugs out. Let me know if that statement is wrong and if anyone has suggestions on another turbo for a low boost application with a t3/t4 flange let me know.

Re: Turbo 4AGE
 

Thats why I buy with a credit card, so not only can I ---- the world when I dont pay, but I can dispute ---- when its not right and I cant get the seller to make good on it
