So Were not rich but we arent stupid

The Turbo-Fire 265 SBC was introduced in the "Motoramic" 1955 Chevrolet, not the "Motormatic" '55 Chevy.   I saw it on a t-shirt.

Otherwise, a pretty fair fact summary. 

You ought to work in the "Glass House" the way you promote the Blue Oval!

news  flash  for  you...

a  j/y  turbo  build up  ain't gonna  be cheap...

great you get the turbo/intr/  etc  cheap !!!!!!!!!

but   the  e.f.i. system needed to run a set up on a bigblock is by no means  cheap...

and  we've seen  what a carb and turbo  do  when put together...

turbo  t/a   or a buick t-type 77-81 

no to do a j/y build  u'd need it fuel injected  and that aint cheap...

thats why u'r idea  falls on deaf ears.....

an efi  for the  bellybutton  bigblock chevy  is over 2500.00  + fuel pump/lines/etc..   not cheap   and  brings your idea to a 3-4 g's  build up....not cheap...  sorry...

adapting a turbo into a blower like a paxton/vortec   that be cheap and works  with a fuel setup the guys already got(just a few mod's)  that be a nice story...   two  j/y  hairdriers made into blowers and see what it  makes...(shouldn't be to hard to spin um up fast enough for mid to high rpm  push....

I disagree.

There's at least one guy in the SEVENS (Brad Tyson, 7.86 at 180) with a turbo Mustang blowing through the carb.  http://www.turbomustangs.com/forums/showthread.php?s=&threadid=22237

There's even guys BUILDING carbs for these kinds of fun and games. http://www.tpcracing.com/C-race-Blowthrough.html

Just because chinzy GM couldn't figure out how to carb a turbo (sucking through a 5-cent Rochester) doesn't mean that others in the last twenty-five years haven't.  Lots of JY turbo message boards on how to do this. http://www.boards2go.com/boards/board.cgi?&user=huntracers

 Besides, if Paxton and Vortech (not to mention Gale Banks's old systems, and JY legend Mike Sitar) can blow through the carb, a turbo ought to be able to if midrange on-boost enrichment is sorted out.

As to EFI, a Car Crafty shopper could do EFI on a big-block for less than $2,500. Jy parts (460s and 454s have been injected for years) plus a homebuilt Megasquirt or an SDS brain-box and maybe homebuilt fuel rails ought to work.  Sure, EFI would be better and would take some work to stay cheap, but a blow-through carb'ed turbo would be cheap-n-dirty.

Compared to a $12,000+ stroker, a $4,000-$7,000 488+cube turbo engine IS CHEAP! And keeping a 1000+horse N20 engine bottle-fed isn't exactly a "budget" proposition, either.   

I doubt CC will do it because nobody is going to give them any free parts and you have to use your brain to do it. But obvious misinformation shouldn't be allowed to stand.  Right, Doc?

As mentioned by MrFoMoCo it doesn't have to be that expensive. A preboxed kit costs $2500+ but that doesn't mean you can't assemble your own for less. If you were to scavenge a full set of EFI sensors and ignition off of a late model junkyard BBC, buy a new fuel pump and injectors then control it with a megasquirt you could probably get a BB EFI system together for under $1500. Not as cheap as a carburetor but not $2500+ either.

Another reasonably priced EFI option would be to salvage an EFI 5.0 mustang engine and invest in a twEECer. EFI isn't for everybody but that hardly turns it into unobtainium.

I'd like to see a jy turbo project and you could use my car.  I know the whole which marque to use debate will range to no end till people switch discusions and it carries on there, but personally Id like to see a twin turbo 427.  The jy's have many bb ambulances, which often go untouched.  Yeah my cars a chevelle so you have alot more engine bay than a pony car for all that ducting.  Does the tubing have to be mandrell bent shiny stuff or could one weld up some flat sheet metal and just round it out at the junction to the IC? would a couple of 14bs be adequate as they would spool up quick or would a t3/t4 ball bering unit be in order?  FMIC or CMIC or SMIC?  Cheapest bov?  Best jy oil controll or would switching to dry sump be better.  Maybe they could build it then switch out all the most popular brand turbo's let us know the difference in spool up where they taper of etc... Best cams, ignitions, for said combo.  How to boost index our own carb.  best plug temps to run along with thermostats.  How much advantage idexing plugs gives under boost.  ETC...  

nice links..cool  reading  thanks..

but  um...  how many  fuel ijt.  bigblock  u seen in a junkyard???!!!!

to  get injectors/etc...  and  tbi doesn't  count...as it's nobetter than a carb...

there isn't any(at least around  here) and if there was  they  aren't parting out the engine...

the  7 sec.  racers mustang  is  cool  but how much "help" he get tuning it!!!!! 

I'd love to  try it...  but it isn't cheap if you break parts because it isn't tuned  right...

like anything....  you can make a cheap j/y build but problems of  parts aval.. in  j/y's and a persons  free time he/she has to go"look" for said parts  needs to be looked at  too...

most  j/y's  nowadays  know  what they got and don't just hand you a turbo  for 25 bucks....  even if you pick it...

a turbo  is like n.o.s.   you run it  lean  and you break stuff...

turbo's  you need a chas  dyno  to tune it so that doesn't happen   or  run it rich(loose power) dyno  time isn't handed out for free either...

it  be a great idea  but too many things in the way of making it a cheap  d u i j/y  build  up....

can it be done...  no doubt...  but can it be done by alot of people using  j/y as a parts surplier...   no  as there isn't enough parts in there to make it happen.....

if  I see a j/y  build  I want to be able to go to a few j/y and get the parts and  start...   if the parts aren't in the j/y's (in big  numbers)  then it be hart to copy  a build up  like that....

Then how does Vortech do it on GM Vortecs?

Or Procharger?

Finally, here's some fun stuff about a JY EFI 460 with way-too small turbos (HINT: don't use small T3s on a serious big block turbo) and no intercooler (imagine what this car could do if it had adequate turbos, intercooling, cam, heads, tuning, tires, suspension . . . . But it was dirt cheap and homebuilt) http://www.undrprsr.com/fairmont/

Great questions that a CC project could answer for all of us.  

"funny  hows  vortech  do it on vortec's"

not with j/y  parts...

and  vortec's arenot carb.(ed)

again  show my a line of  bigblock ford/chevy fuel inj.  engines in a j/y  to steel/rape for parts.....

or a line of cars with turbo's  ready and waiting????!!!!!!!!!!

thats the problem...  there are some parts in j/y's  for the few that try it  but  not widespread parts avalablity ,that alot of people could  start looking for the parts needed to make a set up  from  j/y  parts...

some people try making a set up themselves and that great..  but  there is alot of fab.ing to do on a set up to get it up and  running only to melt it down cause of a tuning error...

turbo's are unforgiving if not tuned correctly.... and kept up...

I don't understand.

Half the folks are writing that the JYs are loaded with Gen III LS plants-- which only hit the street in 1997--, but there are no EFIs to "steel/rape" parts from for a big block turbo project?  My earlier post was specifically about blowing through TBI, which can be done because Vortech and Procharger both do it on TBI trucks.

Big block trucks have been injected for over a decade. If the JY is so full of C-H-E-A-P Gen III, then surely there are some EFI trucks in there,  too.

Turbos can come from a variety of places, including rebuilders, salvages, importers.  Big engines need bigger turbos, such as on Powerstroke/Cummins/Duramax diesels, tractors, etc. And lots of turbos are for sale on eBay and elsewhere.

That's part of what CC should do in the story is discuss how to select and find affordable turbos (not the latest "hi-fi" ceramic-wheel, ball-bearing exotic racing turbos).  

Y'all still bangin' dis thread?

You and Doc give it up. 

Mos these duct-tape hillbillies couldn't figure out a turbo hook up even if came wit a free weekend wit Pamela Anderson when they finished.   They probably be hookin the exhaust to th compressor . . . .

o k  you don't understand.... I'll  help  you

454 bigblock and 460 ford block  come into the j/y  o k  with me so far??!!

the  j/y  owner  then calls  a machine shop that buys the engine before the truck gets to the lot part of the j/y for you to see..

or  (2) the  j/y  owner pulls the engine so the engine stays together in one piece for someone looking for that engines... 

most j/y's at least around here  know what stuffs worth and the bigblocks are like gold to them and their friends  so they 're gone befor you or I can get our hands near them...  with me so far..

machine shops are always looking for "cores" and j/y's know it... so ls1's might be in j/y's in  #'s  but bigblocks aren't...

if you find a bigblock in a j/y  nowadays there is a reason it's still there!!!!!!!!

maybe things are differant where  you are  but I've been to many j/y's in many states and I see that the days of j/y  owners not knowing what they got and "saving the good stuff from the guys that trash everything else to get what they need(you've seen um) " and it's put aside  out of harms way..

and if you think they'll sell just part of the engine you're in for a surprize...

like I said  I like the idea  but  the parts are not there to do a j/y big block turbo engine build.....

f y i    ls1  are takin out of the cars around here also before the car hits the yard...

Junkyard big blocks are impossible to find without spending serious coin.  The cheapest one i've found in my area for a complete 79 454 was 1200 dollars!  That's downright ridiculous.  There aren't any diesels in the yards I go to either, so there's no way to scavenge a turbo off of some old powerstroke.  These guys need to get a clue.

I think it's regional Mitch. As of 2 weeks ago there were 7 turbochargers in the local wrecking yard. I haven't been to a commercial truck wrecker in a while but over half of those diesels have turbos attached. The EFI is there as well, you just have to put in a request for a complete harness and sensors with the yard's office. That stuff is usually locked up in a shed to keep morons from cutting up an intact harness. You can head them off at the pass as well and hit up the tow yards. Some tow yards will sell parts off of totaled cars that are headed to the wrecker.

I believe it's feasible but I don't think the interest is really there for most of the readers though. It'll eventually happen but there'll need to be more pioneers who sort out the unfamiliar territory.

Joe

That's probably part of it, but I live in farm country so you'd think there would be diesels around somewhere.  Believe it or not, one of my local yards doesn't even have any rwd transmissions anymore.  They don't even have v8's anymore!  Personally, turbos don't interest me but i'm just one guy.  I am kind of kickin around the idea of puttin a 496 together though.  What the hell, gas is gonna be 2.50 a gallon might as well make the 10 mpg worth it.
