Having trouble swapping from NA to turbo

[jomz shakes]

Ok I've got my 280zx that I just bought , it's a 1982 NA 5 speed

-I've found a guy that will replace my engine with a rebuilt 1983 turbo engine

Here's the stuff Im aware i need so far

-smog stuff , knock sensor ,relays

-turbo ecu

-turbo distributor w ignitor

-new spark plugs

-turbo injectors, o rings , and harness clips

-2.5 exhaust

-air flow meter

-turbo oil line

-j piPe

-turbo clutch and flywheel w new throwing bearing

 

I'm planning on keeping it smoggable but adding a boost controller and blow off valve, running 12 psi w no I tercooler

 

Here the 2 problems I have "if there's any other u can see let me know"

- I can not find a turbo egr tube

I'm planning on swapping my egr onto the turbo engine but I need a turbo egr tube

Is it that hard to find this part??

 

- someone is telling me if I keep my stock t5 NA 1982 transmission and grab a turbo clutch/flywheel that the collar is the wrong size, he mentioned I need a collar of a 240sx.

To be honest I don't know what a "collar" is so I really want to know exactly what to buy

You need to check out the FAQ section. Many many writeups. Also the stock turbo EGR tube comes off the downpipe elbow, I have one for $20 but you need to use the stock turbo or something similar. Just use whatever clutch/flywheel you have now or upgrade them with NA 225mm clutch stage 2 or something and you should be fine, problem solved.

Wait I bought a stock turbo clutch/flywheel thinking it was better, is the NA clutch better to use?

 

And can u call me I want that egr tube 650-867-5567 james

What collar do I buy I can not find it?

 

And is the turbo flywheel lighter or heavyier?

I don't know weather or not a turbo flywheel and clutch will fit with an n/a 5 speed, never dealt with a turbo 5 speed. i just used a stock 2+2 flywheel and clutch. its a little bigger than the coupe clutch, Seems to hold fine in my turbo car

[jomz shakes]

ive understood that it will fit but the collar behind the bearing must be the right size. this is what i Know so far.

 

the guy that sold me the clutch/flywheel told me that the collars may not be the right size,

its l28et clutch and flywheel going into a 1982 NA 5 speed transmission.

 

he mentioned using a collar that fits on a 240sx,

im guessing it was for a sr20 thou?

anyone?

Calvin, the turbo clutch/flywheel is the same as a 2+2 clutch flywheel. 240mm grip surface. the coupes has 225mm.

 

-If it's 225mm wide then you have a coupe version which uses a 550lb pressure-plate.

- If it's 240mm wide then you have a 2+2/turbo version with a 780lb plate and a wider disc.

- Flywheels are identical in diameter and weight at 23 lbs (only the contact area is wider).

 

Unless you're racing you can usually get by with an OEM style clutch because the 240Z is so light...I have been autocrossing and dragracing for years with an OEM with no issues. But this year when I added my triple Webers the clutch began to slip when the engine hit its torque peak. I decided it was time to upgrade and installed a standard Centerforce II. The Centerforce fits perfectly and will actually chirp into 3rd gear on shifting. Pedal feel is excellent and engages smoothly.

 

- A Zcar 5-speed will fit on any year Z block and any year L28 clutch can be used. But the throwout bearing "collar" must match the style of the flywheel (coupe or 2+2). In other words, if you have a 2+2 flywheel, you need to change the throwout collar to a 2+2 version. A coupe flywheel uses a coupe collar.
