yeh basically you will need an 1982-1983 280ZX turbo dizzy...
it has the CAS built inside the dizzy... =)
So you need to get the dizzy.. and the oil pump/dizzy shaft from the 280ZX turbo dizzy.. because the stock N/A will not fit...
You need to remove the N/A dizzy.. and the lower dizzy housing.. then unbolt the oil pump and drop it down. I needed to drop the fron sway bar to pull the oil pump down all the way....
then pull out the N/A oil shaft.. and put in the new turbo shaft... and bolt the oil pump back on.. and swaybar back on...
go back up to the dizzy and bolt her up..

-
i've never seen this.. i could be done.. BUT i wouldnt recommend it..
go out.. and buy a good external wastegate.. =) save ya the trouble.. or buy a used T3.. like on eBay right now
-
I leaned out the AFM about 35 teeth.. and still no luck...
it's ok.. N/A inject are in
-
ok..
i am running overly overly rich..
i swapped out the 310cc injectors and put back in my N/A injectors and I will run low boost...
havent driven it yet but it runs and revs fine
-
Ok... something new...
It WONT rev past 2,000 RPM...
Which is why when I try driving it wont run past 2,000 RPM... hmm
I have an FSM actually for my car.. i tried looking.. and no luck..
I also unplugged the TPS to see if it was bad .. but it still didnt run past 2,000 RPM with or without the TPS...
I didn't swap in a WHOLE new engine..
I just used my stock N47 head and block which was already in my car and I did a manifold swap... and with some 310cc injectors

Hey guys.. I just finished my turbo swap... and I started her up this morning and she idle'd and ran fine... and it revved great!!
BUT when I backed her out into the street and put it in first gear and started to engage the clutch the engine started cutting out and died...
What could be wrong with it? I checked all electrical connections that I could and I checked for spark and good fuel pressure and it's fine..
But what the hell could be wrong with it??
here are some pics

Hey guys..
I am doing my turbo swap next week.. with my Z31 turbo.. and I will be using the Z31 downpipe..
and I just bought a 3" downpipe, and there is one minor problem...
the Z31 turbo has the following :
Turbo charger
Downpipe, O2 elbow and wastegate housing attached as one
the 280ZX turbo has the following :
Turbo charger
Wastegate housing bolted onto the turbo
Then the downpipe and O2 elbow
This is the downpipe courtesy to Jared!
Now I know I should post this in the classifieds.. i've been here for 2 years.. but I need HELP bad from you guys!!
Does anyone have a spare wastegate housing from a 280ZX turbo?
I have the turbo and the new 3" SS downpipe hehe.. but I need the wastegate housing which holds the wastegate flapper...
Thanks guys! please please help me out!
-
wow!! very nice numbers!!!
I hope I can get those numbers some day... =)
well find out next week when I do my swap..
upload that video!!
-

anyone have a good answer?
-

hey bastaad.. nice wheels.. now ya just need to polish them up like I did!
BTW - what size intercooler piping did you use to clear the stock fan and dizzy?
I have 2.5" piping.. hoping it'll fit

Hey guys..
I will be bolting on my turbo to my N47 head and block in a few weeks... and I am trying to figure out timing...
now I have the vaccum advance dizzy on my 1978 280Z... and I am trying to figure out how to "tune" it.. or make it run right with 10psi....
I've read of people using silicone or JBweld to "seal" up or close off the advance slots to prevent too much advance under boost...
I have a problem picturing this..
How do I seal or close up the advance slots?
Within a month of my conversion I will being MegaSquirt with the help of Moby.. but I would like to see how it runs on N/A electronics first...
Also.. I have read on the forums that the N/A vacuum advance dizzy's are easy to tune.. both mechanically and with a timing light.. so I can choose to advance or retard it by hand basically .. compared to the turbo or ZX dizzy's.. (i know Tony D is going to say there is NO turbo dizzy.. but anyway)
I checked BLUE's tech tips page and read up on adjusting the timing and dizzy.. but i dont understand the advance "slots"

bastaad25..
do you have ANY pics of your car..
I would LOVE to see your car..and some shots of the engine bay and intercooler setup!!
-
nm answered my own question...
-
Jersey did you have to cut your radiator support to fit in those pipes? Or did you use the existing holes?
-

----------------------------
Enter the VES (Virtual Exhaust System)…….A system that works “on demand†at the onset of boost on turbo and supercharged vehicles to free up all the backpressure (just as a large exhaust system would) in the exhaust stream so the engine can make maximum power. The VES system works as an active dump tube that completely bypasses the restrictive exhaust system when boost is present. As soon as the turbo spools, the valve begins to open. By the time the turbo makes full boost, the valve is fully open.
Highlights of the way VES works:
* Completely quiet and stock-like sounding during startup, idle, and cruising.
* 0 delay in valve response to boost, yet very smooth transition into boost mode.
* Automatic open/close under boost using existing boost source on turbo engine and does not rely on wing nuts or electrical motors.
* Integrate a boost controller to control when the valve opens or completely turn it off.
* Addresses virtually all complaints associated with large 3†cat-back exhaust systems.

Anyone think this is a true performer.. or some cheapo gimmick?!?

Thanks!
Intake flutter
in Turbo / Supercharger
Posted
bastaad525 the reason why you STILL hear a flutter, with a BOV, is because the spring for the BOV could be too tight...
When its really tight, or your DSM BOV was crushed, the spring will open and close, open and close, and open and close really fast.
If the spring was loose, the valve will stay open untill the vacuum tells it to close.
The Greddy Type S BOV allows you to adjust the spring tension.. and with it really tight, you will hear it flutter, with it loose you will simply hear a Pshhh.
I personally LOVE flutter sounds, reminds me of the old Audi Quattro Group B rally car, and the older Subaru WRX's in the WRC =)
