How much would i be looking at for a turbo charger on my 86 iroc with a 305 TPI

 

You've left alot of factors out, what are your performance goals? What our your fab resources. Can you do alot of it yourself. I've heard guys claim over at turbomustangs that they've put together junkyard systems for around $1200, but I'd consider that the bargain basement end. Consider that you'll have hundred$ in mods to the fuel system alone.

 

Ill sell ya my setup for 1500 with meth setup and boost gauge.

lol

 

i sense sarcasm, but if your by any chance serious, please email me or PM, i am very ineterested, as i am about to purchase a large order or turbo parts and accessories and have cash in hand. thank you.

Here is a rough list for the latest plow truck single turbo setup:

$230 64mm / .76 A/R Holset turbo (new take off)
$200 24x12x4.5 Griffin intercooler and 1/8" alum plate for end tanks,argon,rod
$150 Mcmaster Carr 1.6 ID pipes,elbows, 3/8" steel for header flange at head
$280 Ford fuel injectors (8 new)
$200 Silicone couplers & T-bolt clamps
$100 cold side plumbing
$50 S/S drain line & fittings
$10 oil inlet line
$150 exhaust pipes,flanges,T-bolt clamps
$50 big air filter K&N
$60 2-bar MAP sensor
$15 exh. manifold gaskets
$15 exh. manifold bolts (1" long ARP)
$00 DIY PROM tuning (or prom burner $50-$150)

optional
$70 VW compressor bypass valve, hose, pipes
$250 Water/Meth injection

 

The first setup...about $1600. Could that kit have been cheaper, YES

$230 64mm / .76 A/R Holset turbo (new take off)
$000 No intercooler
$10 Stock TPI manifolds with 1/4" welded to them (steel from junkyard,etc)
$60 stock fuel injectors with nitrous solenoid and jet
$80 rubber couplers, screw clamps
$50 No intercooler(less pipes), cold side plumbing, junkyard car exhaust
$50 S/S drain line & fittings (don't scimp here)
$10 oil inlet line
$100 exhaust pipes from junkyard,flanges,T-bolt clamps
$00 stock air filter
$20 Diesel 3-bar MAP sensor along with a stock 1-bar sensor (code mods)
$10 exh. manifold gaskets
$00 stock TPI bolts
$00 DIY PROM tuning (or prom burner $50-$150)

* Requires a day at the junkyard and steel recycle place
TOTAL: $600-$700

 

junkclctr, not to be argumentative, but aren't you neglecting fuel delivery upgrades? Even if his stock pump and lines will feed it (unlikely unless his goals are really mild) his FPR is not boost ref'd. He'd at least need a different fuel pressure regulator, wouldn't he?

 

Questions are good. The first setup used bigger Ford injectors. That is actually how I am setting it up (Ford 42#/hr). The second cheap setup used a nitrous fuel solenoid and injector.

EDIT: The stock lines are fine up to a point. I would go with a bigger fuel pump over stock for 400+ HP.

 

Ahh, I wondered about the nitrous solenoid! I wondered why you wanted him to run nitrous. You were using it for fuel enrichment!? I missed your point there.........

Don't you still need boost ref. regulator for a turbo app? That was my understanding.

 

If you're talking about a FMU, you don't need one. That's one way to do it but you dont have to and preferably with a stock pump, shouldn't.

The stock regulator is vac/boost referenced. For every PSI of boost it will raise fuel pressure by 1 psi, which cancels out with the air pressure in the manifold that the fuel is spraying against. So in the end it will just maintain your stock pressure.

 

I never knew that stock non turbo'd cars came with boost ref'd FPR's.

 

TPI cars use a vacuum referenced fuel regulator for less pressure at idle. So when boost hits the diaphragm its just a 1:1 increase, which as I said has no effect because of the pressure differential remains the same.
