Pics of 70 series tacs?

[VTCruiser]

Hey all,

I am looking for info/pics on HZJ7X tacs. My primary concern is fuel pump pick up and tac size. Ideally i would like to mount it in the stock 60 series location....any used units out there?

Thanks

AWESOME , thanks stickboy.

Where is the pick up for that tac? Fuel pump or bellhousing? It would probably be easier to find a BJ7_ tac rather than a HZJ7_ tac if it would work....

What are those LEDs for? I love how it say turbo....

Bellhousing VT. I don't recall what thread it was where I posted a picture of the sending unit on the bellhousing of the 13BT. It's somewhere in here...

green light = regular boost
red light = over boost

Why not use a tach and sender from a BJ60(12v) or HJ60 (24V)?

Doesn't your bellhousing have the hole for the sender?

sweet...

lowenbrau - the truck is an HJ, but their tacs use pick-ups at the bell housing which has a different calibration than fuel pump pick up on the 1HZ. Because the h55f is the one that came with the 1HZ, i am pretty sure it does not have the bell housing sender.

I'll have to look at the 1hz flywheel in the shop but I suspect it has the same number of teeth as the 2H. The pickup just counts teeth.

I don't know that my bell housing has a mount for the sensor either (?). I'll check for it...
