Cheers mate
I think they were from a turbo pulsar
They needed machining to suit whatever bore and height you have

I got my parts off Ernie (atr racing he's on forum) and got everything machined to suit

I think its fantastic, if it more affordable I will buy one
I also like the 09 kit but at 7.3k cant justify it

definitely, in Aus 60a 4sp generally sell for around $200 and the 60a 5speed is 800-850
56a 4speeds = $50

sorry i think it was nismo head gasket from memory parts guys said they are good for turbo setups

no DD not yellow, I tried yellow its not stiff enough.

The turbo spring is what the guys at SU midel call it. It doesnt have a colour at either end. It is a fair bit longer than the yellow

Ok here is more info & pics

here is the HS6 SU setup




into turbo




and another




Turbo is a T25 Garrett KTT .48 AR front and rear
it comes on boost around 3000 rpm and is currently running wastegate pressure of 8psi as Im running the new motor in.

I have an A14 with turbo cam, pistons and rings. H89 head, turbo head gasket and arp studs with double valve springs

SU is a rebuild HS6 running BCA needle profile and the "turbo" spring from SU midel with standard SU oil also from SU midel.
Dizzy is recurved 12-26 degrees

I still have heaps to do but its running and driveable.

I have updates but will post into my old original thread to help others:
http://datsun1200.com/modules/newbb/v ... id=482740#forumpost482740

long story short the needle you want or that will at least get you closest is a BCA profile

the rest of the info will be in my other thread

Ok I pick the car up from the tuners today. Unfortunately I dont have any dyno figures as his dyno isnt calibrated and he only uses it to tune.

Currently I'm running 8psi straight off wastegate as the motor is new and I need to run it in. I have some helpful info for others considering SU drawthrough.

The needle that I purchased from SU midel that the gentlemen did a "best guess" was actually a really good guess. The needle profile worked and didnt require any filing or modifying.

The needle I'm using is a BCA

here is an excellent website that visually maps the fuel profiles of needles:

I am speaking to the turner this arvo on pickup and will confirm spring, oil etc for others

ah yes makes sense mine is on my a14

I have a 50A that an autosparkie friend found for me. Bolts straight on and works with the standard regulators. If people are interested I will take some pics and get a part number for you

Thanks DD great numbers I can quote to tuners/queries regarding fuel supply

Thanks for info Dave. I understand exactly what you are saying, I have played with the jet screw heaps trying to tune it.

General info I have been told is that you shouldn't be able to start the car without the choke on. If you can its set too rich for idle.

What you said re needle is exactly what I was expecting to have to do. The issue I have is the other variables that need to be fixed before you start to custom change the needle profile.

To be honest I think its beyond me. I have found a reputable tuner and have booked it in with him. I will let everyone know the results.

Once its running well I will note all the variables exactly and measure the needle profile with a vernier at the 16 spots so others can have a closer start point than me.

To be honest the entire turbo process has been so much more complex and involved than many people eluded to on the forums when I was first asking years ago.

To anyone considering this IMO if you have gone this far do it properly with EFI
