whats the best turbo and how much approx and how long to install.
i saw import killers turbo setup so i understand the attachments and all that. does the turbo need an oiling system attached or is it self lubing?
dont know much about turbos.

does having the muffler hooked up to the turbo effect the exhaust flow or does it not matter with so much air being forced into the carb.
 
I don't know much about turbos, either. :)

The turbo itself does a good job of muffling the exhaust, but further sound reduction is generally desired for legal reasons. A turbo has a large exhaust fitted, as restricted flow after the turbo, will cause pressure buildup and loss of turbo effect.

Turbos sure do need a good quality oil supply. It has to be turbo-grade oil, pressure is high and flow must be maintained always. The oil has to drain to the oil pan as directly as possible, in order to preserve oil quality (lack of excess heat or bubbles) and ideal flow.

Some of the experts might chime in now...

what sorta engine is it?
what sorta driving you want to do?
what budget do you want to do it in?(cheap.. average.. reliable... full blown)
how mechanical are you?
willing to learn?

asking a broad general question will get you a braod general answer which wont really help you.

give us some info as with what you want to do

cheers.joe.
 
Turbo 6 = Easy work.

Seriously. Import Killas car had to be about the easiest thing in the world to turbo. You need to T off the oil pressure seding unit port on the side of the block, you will need to tap a hole in the oil pan ABOVE the oil line for a return. You need to fab up a pipe off the manifold to feed the turbo, and you have to fab up a down pipe.

A T3 turbo off a T-bird TurboCoupe, SVO, Merkur, Grand National, etc. etc. Will work about perfectly on a 200. These are fairly easy to find, and not very expensive. Sometimes you can luck up on one needing a rebuild for $50 or less. Check the junkyards!! Avoid the T3 off od the turbo Mopars, they are a bit different, and not as good.
 
i have a I6 250 in a merc. monarch and right now i dont do too much driving but i will soon start another job which takes about 1/4 tank of gas to get there and back home. Im dont mind filling up more often as long as gas i dont have to switch to a higher octane gas, i use reg gas cause the higher octane suff does nothing right now. Im not extremely mechanical but i know my I6, ive swapped torn apart and fixed quite a bit on it. I like to get good deals but if necessary will spend more $$ for a job well done. I like import killers turbo system too. thanks for advice. keep it coming.
 
a turbo will not use any more or any less fuel so long as you dont go into boost. so if you drive your car like a normal person mpg will stay the same.

My suggestions would be to read some books, there is much information to be learned. Search through the forums theres lots of turbo info here

And air being forced into the turbo is no good if if it cant get out the exhaust. a straight through muffler is sufficient

low grade fuel + turbo will make a loud boom sound in your motor, so unless you want that use the good stuff

And the more you know the cheaper everything will be. I plan on welding my own piping and doing pretty much all the work myself, so that will keep costs down to a minimum.
 
hey back home I got some 2.3L turbo oil blocks sitting collecting dust I can let got for $5 plus ship. they are a 1/4" NPT thread with a 1/4" NPT hole for a sender and a 1/4" inverted flare port (brake line) you can get a inverted flare fitting for the turbo and plumb it using brake line then (just route around back of block) I have a couple stock drain tubes also for t3's around (switching my merk to all braided lines)

sounds like a good deal, i dont know how much they normally are, what exactly is an oil block, is it part of the turbo or a seperate oil pan type deal, does this sound good to anybodyele out ther and should i get it/them.

Dave
 
wher did u get the carb cover for your turbo, i have minimal room under the hood and that looks pretty sleek.

dave
 
The oil block he is referring to is what you need to get oil TO the turbo.



The carb hat on Dans stang is kinda a one off deal. It only works with the hollay 2bbl, and it has to be modified. The hat itself is off of a Jeep G.C. V-8



Honestly, to me, I think you would be better off with a well built/tuned N/A combo than with a turbo. If your not willing to step up to high octane fuel, then you need to give up the thoughts of turbos.
 
i dont think id mind using high octane fuel since the mileage doest change unless u boost so a turbo still sounds good to me. How much more power will i get on a stock 250 with dbl bbl carb and adapter if i went turbo or shaved the head and got a header. I plan to get a 260 deg cam anyway.
the reason im looking into the tubo is because from wat i hear its cheaper than buying a header and gives more power.

the more info the better, i love learning about the amazin six.

thanx for all the advice andu can still keep it coming cause im absorbing the info into my little noggin.

ok for a 250...

go straight for a t04 turbo.

you can run the set up draw thru or blow thru with draw thru being the cheaper, easier option.

i'd suggest a 8 psi boost limit to a stock engine with the stock compression ratio.

to run the turbo you'll need to have a exhaust manifold made up,

you could use the standard exhaust manifold with a j-pipe to the turbo.

with a camshaft, turbo's dont like aggressive grinds, it makes spool time longer, a stage 1 or 2 cam (also known as a towing cam) is ideal for the turbo set ups.

do a search on the boards, theres plenty on here, with my self posting a fair bit of info. factor in at least 3 hrs for this one :wink: lol

cheers.joe.
 
I'm kinda interested in this, so I have to ask.... :)

So a T3 is too small for a 250?

If so, what cars came factory with a T04?
 
really a .60 trim t3 comressor is plenty for under 12 psi of boost but you really need a .82 turbine might be able to squeak by on a .63 but it would be close. the oil block will go in place of the oil sender ont eh block and then your sender can be placed in it and a $6 brake line bent to feed the turbo oil. for a return you should drop the pan an weld a bung in bout you could jus tpunch a hole and epoxy in a fitting

a to4 is a better option if you know you will be playing with the engine more later down the track.

but 62 fairlane is right..

an exhaust housing size of ar .82 is good for a stock 250ci engine copping mild boost levels.

thing you have to remember is, you have 4.1lt working for you, a t04 is an excelent choice, as spool will occur around 2600rpm... which is good.

you dont want to be driving on boost all day, especially if you drive on the highways alot, all your doing is wasting fuel. set the turbo to kick in from about half of your rev range.

cheers.joe.
 
I am looking into power stokre turbos.

the big truck guys like to upgrade too so their old ones can be had cheap. not to mention that a NEW turbo for a cummings can be bought for only $500 or so. that is the route I am going now...might use my little t3 to get it up and running for now but ultimatly I am giong for high boost levels on a 250...like 18psi. crunch the numbers and there are NICE

nick
 
Are there any cars/trucks that came stock with a t04? I was just wondering in case I spy one when I'm out at the 'yard...
 
not many did.

the rx7 single turbo rotor's run a t04

but the largest common one you will find will be a t3 from a single turbo nissan 300zx with the .82 exhaust housing and decent size compressor- they are almost the size of a small t04, and can be had for cheap money

check e-bay for a t04 theres a few there.

cheers.joe.
 
how do you set up when the turbo will boost via rpm?
does it work on vacuum or adjustable needle or what
