I have a sport coupe (manual) new tranny and I was wondering if you guys have any tips or steps on going about putting a turbo on my stock engine... decent shape and only 63k miles....and yes it currently runs

 

im all for putting turbos on these engines BUT seeing how u have the weaker carbed engine i highly suggest against it

the carbed 2.8 motors have cranks with smaller mains , and are prone to breaking and spining bearings, the other difference is the heads have smaller valves then the fuel injected motors

to do a proper carb setup with a turbo u would have to ditch the factory carb and get an eldelbrock intake with the 4bl carb upper plenum which is a few hundred bucks

then u would need a holley 4150 series carb with mechanical secondarys and i dont belive they make one small enough to run on the v6, though id have to poke around a bit but u may be able to modify a holley 2 barrell carb to work wich would save u the cost of the intake since it should bolt onto the factory one


if u really want to go turbo my best advice would be to do an engine swap and ecm swap first

i would swap in a 90-92 ecm and harness and 3.1L engine
or a 93-94 3.4 motor with the 90-92 ecm and harness

though just getting a 3.1 out of a 90-92 with ecm and harness would be much easier

this will pick up a bunch of power over what u have now and will be much better suited to being turbocharged down the road

 

i also see u live in the state of ca

the 3.1 and ecm swap will be legal if u retian all the emission equip, which u would get with the new motor

but u will never get a turbo setup to pass inspection in that state with the hellish emisions laws

u would have to remove it and go back to stock everytime u needed an inspection , unles su know somone who will pass ur car no matter what but from what i hear thats very hard to do in ca

 

ok thanks...I wasnt sure if whether or not i needed to do a swap before I went turbo... i guess ill stop by the local pick n pull... oh n also would my tranny fit the "new" engine after I swap? I would like this to be budget friendly

 

about that... lets say i know a guy haha

 

u could very well turbo ur current engine if u wanted to but i wouldnt

yes ur trans will bolt to the new engine

do u have the 5 speed or 4 speed trans ?
the clutch may become an issue at some point depending on how much power u want to make anything more then say 7psi its real iffy if the stock clutch will hold or start slippping .

by 12 psi i can tell u the stock clutch will deffinatly start slipping

 

if u find a donor car in the junkyard dont forget to grab the sending unit out of the fuel tank, though u can prolly modify ur current one to accept a fuel injection fuel pump

once u get the ecm and motor swap done u could get it turboed for around 8-900 bucks if u can do all ur own work or dont have to pay for labor

 

5 speed...ill buy aftermarket clutch no prob but right now its stock clutch....

 

stick with a spec clutch specclutches.com or whatever it is
the ram clutches are junk and dont hold worth a dam

a member here who bought a stage 3 clutch for his car had goten it so all tgo members got a discount i dont know if thats still active though

 

ok Ill check it out...would you advise to get stage 2? or just stage 1? is there a big difference in performance?

 

they are rated by holding power.

if u do a 3.1 swap and throw a cam in and port the heads/intake i would go with a stage 2 actually make that a stage 3 since its cheaper and holds more power

if ur just going to turbo the stock engine without any other work a stage 1 should be just fine

the last 5 speed camaro i helped turbocharge i told him to go with a stage 3 clutch since he had a 3.4 with a cam and fully ported heads and intake

on my 3.1 with heads/cam/intake it made 370 ftlbs of tq at the rear tires with a messed up ignition system so say 430 ftlbs at the flywheel and that wa sonly at 9 pounds of boost

relistically now that the ignition system is fixed it prolly makes dam near 500ftlbs at 9 psi

so going to the stage 2/3 clutch wouldnt be a bad idea

stage 1 holds 485ftlbs
stage 2 holds 550ftlbs
stage 3 holds 650 ftlbs

though i should warn u about the t5 transmission it will give up long before the stage 1 clutch if u abuse it

if u dont powershift it or sidestep the clutch it will last though

id say the stage1 is a lil less then what u will need in holding capacity if ur going to go for max power and the stage 3 is 20 bucks cheaper then the stage 2

so its upto u between the stage 2 or 3


this page will tell u about each stage of clutch

come on now, the fagoel superchargers were desinged for the early carb motors in trucks, pushing 5-7psi and people didn't have any trouble.

 

they were made for the fuel injected tbi cars and trucks , and they didnt make much power

 

first ones were carb, the TBI plate came later.

owned a NOS one with 2 barrel carb plate.

The early ones were also cogg belt, once it went TBI they had serp belt adapter.

here is the build thread for the one I sold, the guy did go to serp setup but not TBI, he got a 4barrel adapter made.

if he did go with the 4 barrel carb, doesn't he need a turbocharger housing? such as...

does it matter if the secondaries are mechanical or vacuume since it's in the housing?

 

to use a vacum secondary carb u have to have the carb completly enclosed in a box , not just a carb hat.
i belive paxton had a carb box they used to make might have been vortec, but either way they dont work to well
