The 3-port's top port connects to the bleed nipple on the outlet spout of the turbo compressor housing.
The 3-port's middle port goes to the turbo's wastegate actuator housing's nipple. The 3-port's bottom port goes to the bleed return port on the large turbo intake pipe (under the inlet manifold) - or simply left VTA. (If left VTA, then you need to plug that intake port with something suitable, like a screw.) This (very) rough :lol1: diagram might help you visualise it better:- Attachment 56135 |

Does a std 3 port boost soloneid run better than a 2 port and what was the reason they changed from the 2 to 3 port?
|
Cripes, this thread is a blast from the past. ;)
3-port is supposed to control boost better. Don't really know what the reason is though. Actually, it was the first MY93-96 "phase 1" cars which were fitted with the 3-port. Then from MY97, all are fitted with a 2-port, AFAIK. But at OEM boost pressures at least, the 2-port works just fine, anyway. |
Can I just swap the 2 port straight to a 3 port set up

I think you have to have it mapped in, for it to work correctly.
Contact Simon @ Jolly Green Monster (well reknowned mobile mapper) - he'll give you the SP... |

Bringing this back from the dead...
I'll be installing a 3port solenoid on an MY99, should I remove or keep the restrictor pill? Thks. |
Remove it but leave it until the map is done and the mapper will probably do it for you 10min job.
|
Tried it today... no remap, stock MY99 ECU: spikes at 1.16bar then lowers, I can't see how much I can only see the peak on freessm, but I feel it looses power.
No "pill" on the lines just followed joz8968's layout. I think with a proper remap this will probably be able to maintain the 1.1ish bar rill redline. |
