im buildin up a 86 t-bird turbocoupe (sleeper style baby!!!) and i need to kno what 50 trim means...the turbo that comes with the car was a t2/t3 garret. so i was thinkin about movin up to t3/t4. its an 2.8L inline four sohc turbo fuel injected. not bad for 86. its rwd, 5 spd. but im not really into turbos, so if someone could help me out that would be great....

thanx

I dont think that turbo is a t2/t3

I am willing to bet that it is a straight T3 since its manual it should have a lager exhaust like a .63 and the compressor should be a .60, 50 Trim Wheel. Also, Maybe im wrong but I thought those engines were a 2.4L

 

T3 or T4 refers to either the housing or the flange itself. .50 .53. 60 .63 (can be any number) refers to the turbine size. I'd say if you use a .50 trim it'd be to small of a turbo for your 2.8 liter and it'll choke out at a higher psi in higher rpms.

 

The 50 trim T3's are used for 2.2L motors usually

...according to my dad he says its a 2.8, i always thought it was 2.4...but ohwel. so it was a straight t3? so what trim do you think i should go with on the trubo. the exhaust housing is cracked....so i need a new turbo anyways. its oil kooled as of now, i was thinkin a big fmic sprayed black...ummm, ill post tomorrow more about this...im too tired to go on

You are thinking of A/R (area/radius), which is the ratio of the area of the compressor/turbine housing to the radius of the compressor/turbine wheel.

Compressor trim is the squared ratio of the smaller diameter divided by the larger diameter multiplied by 100 of the compressor wheel.

BTW, I hate math.

 

yeah i knew when people say .xx trim the are stating a ratio.

nohondayet - what do you want your goals to be for this car?? Highhorse power/ streetable/ track/ just get it running. Sure you could just buy any turbo but lets see what your goals are. Then i'm sure people will have opinions on what turbo to get and can further help you.

...well, i kno someone that has a 60-1 turbo for sale with a 70 a/r housing. would that suit my 2.4 liter motor ok? but the thing is is that he wants 700 bux for it. it was just recently rebuilt by raceline in cincy ohio (WELL respected shop). but i kno he shouldnt be sellin that high. i could get a new turbo for that much, let alone a bigger one. ive already looked. but he has what i want. what should i offer him????
like i said, i dont kno everyhting about turbos but i do kno a bit...im learnin tho

A 60-1 with .70 A/R is a pretty big turbo. What are your power goals?

 

Even with the liters to back it up a turbo that size will give you mad top end but you won't spool till like 4500 rpm and redline isn't to far after that in that car I'm gonna assume. Go with something else. 700 bucks isn't expensive for a turbo like that but i'd pick a better turbo for your car. Its all about turbo matching to see real power for your car. Then its all about tunning to keep your car running for a while.

Oh man, lots of misinfo in this one. For starters, there's no t2/T3. Second, it's not a 2.8L I4, nor a 2.4L I4, it's a 2.3L 8V. I've owned 2 SVO mustangs and 2 XR4Ti's over the course of my life. All of which come with the identical engine and the SVO's of course comming with the valve cover that reads "Ford 2.3L Turbo". BTW, that Turbo-Poop weighs 3400lbs, which means that the stock 180hp and 220ft/lbs + more mods = ain't getting you nowhere. If you want more advice on your engine check out "www.themerkurdesktop.com, because H-T apparantly is definitely not going to be an accurate source of info for you.

BTW: compressor trim = (inducer x inducer) / (exducer x exducer) x 100 = dosen't tell you jack **** about the turbo other than the ratio of the inducer vs exducer.

P.S. Get an SVO VAM and an 2.5" exhaust and that SloMoCoupe will feel like a whole new car. From there, upgrade keep your stock turbine housing and get a T04S compressor and you'd think it's the fastest land-yacht in the world. Good luck.

I know, but I was mearly pointing out what trim was to the person who was confusing it with A/R.

The intent was good, but the formula you gave was wrong. You stated it as: <TABLE WIDTH="90%" CELLSPACING=0 CELLPADDING=0 ALIGN=CENTER><TR><TD>Quote &raquo;</TD></TR><TR><TD CLASS="quote">Compressor trim is the squared ratio of the smaller diameter divided by the larger diameter multiplied by 100 of the compressor wheel.</TD></TR></TABLE> which would mean:

(Inducer x Inducer)/(Exducer)100 = wrong number. The correct formula is:
(Inducer x Inducer)/(Exducer x Exducer)100 = Trim, which dosen't tell you jack ****.

 

By squared ratio, I meant to square both the inducer and exducer.

 

::here's your shovel::

A ratio is one number/by another number. Squared is that result times it self. So by that reasoning, your formula states:

Trim = (inducer/exducer = n) x n which is even further. But what ever you say...

Just drop it man. The problem was corrected. You made a mistake - it's really no big deal. You can still be the "D-series FI Guru", champ. Don't worry, no one else will know what happened. Life goes on. Geez...

Get the **** off your high horse. I misworded my formula, I said I hate math.

 

Wow. First I try telling you that it's no big deal and it's in the past, and realistically...who cares?! But that wasn't good enough. Is your ego bruised? Get over it man. In reality, if you your self admitted that your math sucks, then why did you offer up a formula that you yourself questioned from the get-go?

you guys crack me up. Here who wants to go first!!


Well since you posted a useless picture I figured I'd add one too. HAHA..enjoy

 

Trying to clarify something that is possibly wrong is one thing, but now you are being a ******* loser...taking time to make a picture specifically for him...gehay.

P.S. What you said about the trim is correct, just in case others care.

 

Yeah you're real mature.

Not only that, but I see you're at 96% already and you've barely been here for a month. That definately says something.

You aren't mature enough to concede that you were wrong, as if it were some massive deal when it wasn't and as you tried to B.S your way out of it, you just buried yourself. My 96% is a result of hurting 2 moderators feelings for illustrating that clearly, they were blatant idiots. However, the fact that you call yourself "D Series FI Guru" and couldn't accurately quote one of the most basic formulas of FI. Now <u>that</u> really says something.

who the hell cares if he was wrong... he was corrected, by you, and now it should be over. he made a mistake, no big deal right?
the picture made me laugh tho, good work, but def over the line.
as for trim, there is no decimal before the trim, ie .50trim is an incorrect figure, it would be 50trim, or whatever trim.

and i think FI d-series guru was trying to correct this guys quote above...
T4 actually refers to both compressor wheel and compressor housing, and exhaust wheel and exhaust housing...
so m any combos available, as for your T3 exhaust a/r's they are generally .36a/r, .48a/r, .63a/r and .82a/r there is a larger exhaust housing but not to many run it. t3 turbine wheels include stg 1, 2, 3, and 5 (t350 wheel).

typical T4 compressor a/r's include .50a/r .60a/r ITS offers a .55a/r E cover, and the .70a/r t04s and R cover. typical t04e wheels are 40trim, 50trim, 57trim, 60trim, 60-1.
blah blah blah...
i doubt the 50trim t3t4e is to big for the application in question.
infact ill plot you one... baed on 2.3L

Edit:::
here is the map i promised...
looks like the e50trim is the perfect compressor for your application...
now depending on which turbine configuration you decide to run, spool up shouldnt be an issue...
now this compressor map is going to give you a ballpark idea of what to expect...
its not exact... im sure you wont be at 15psi at 2000rpm, but for the sake of time i plotted a fixed psi.

lol, I was going to mention that the boost curve isn't nearly that linear, but I see that you already stated that. On a side note, as you cruise around the 'mean streets' of H-T, you'll observe the gross amount of misinformation provided by halfassed builders/tuners and avid comicbook readers. Apparantly, you aren't the typical "n00b", so I'm sure you'll make such observations in short time. As I'm sure you can well imagine, such things are immensely frustrating. In either case, Enjoy!
