From your pic, it looks like you're putting the sensor on the exhaust side?
Are you planning on using the water pump studs to mount your bracket?

Here are a couple pictures of my DIS wheel and mount on my Datsun 240Z, just to give you some ideas.

If you're not living on the edge, you're taking up too much space.

thanks for the ideas.
adjustable bracket is the way to go i think!

i will be mounting my sensor on inlet side same as yours festy.


i plan to get the engine running using the camira inlet manifold pictured at the start of the thread, however i would like to replace it will motorcylcle throttle bodies from a suzuki 02 gsxr 750. if i were to mount the tps on the throttle shaft, and made a vacum block for the map sensor the delco should be able to run it ???

ITBs can be tricky to get a decent MAP reading from at low throttle. You can use a vacuum manifold with restrictors to dampen the pulses but it will probably take a bit of fiddling to get it right. Don't forget your brake booster needs a vacuum line too, although you could switch your alternator for one off a diesel engine (they usually have a vacuum pump on the back of the alternator) or there's also electric vacuum pumps available, they were used on a few v8s (some cadillacs?) that couldn't maintain a decent vacuum at idle.

An adjustable sensor mount is a good idea, as I just found out my engine doesn't want to start with 0' advance.
I made mine fixed position for added rigidity, and it's one less thing that can work loose at the track. But if I'd made it adjustable, I'd probably have it running already :oops:
