Save your money!! Try putting on an cold air induction system then work on the exhaust end. I put one on my 81 and didn't notice much differance. Ken

I would say do them all at the same time, you would notice alot more out of the TB if you put it on after and intake and exhaust compared to before. I would save my money and do it al at once.

I installed it on my 78Z and saw a good power increase, it use to stop pullings at about 5600 rpm now it pulls hard thru 6500 rpm's. I would say get it by all means, however I do have other mods on the Z. Hope this helps.

It may be too big for stock engine. I'm going with 300zxt throttle body with 274 deg cam

and z31 drivers like me

usually remove our stock 300zx 54mm TB and use a 90-91 Stanza ka24e 60mm TB or an 89-91 240sx 60mm ka24e TB. Go figure...

I installed one on mine while I was going through the motor. I am of the opinion that this is NOT a bolt on upgrade since it involves some work to the intake manifold.

The opening in the intake is sized to match the stock TB, so to gain anything out of the larger one, you will need to open the intake manifold up to the size of the new TB. Not something that would be easy or advisable with the intake on the car.
