Those Jenvey's look really nice. And way cheaper than Mikuni

 

Any experience with them?

The factory system is very primitive. A modern efi system with closed loop fueling is miles ahead of the original system. Yes, a complete new system. Very similar to triple mikunis but triple throttle bodies instead. Look up Jenvey's

I really might go that direction.

 

It would be hard to abandon my vision for the car. Maybe ill just come back to it in the future

 

That is one of the greatest things about these S30s. You can continue to work on them and change them

Follow Up:

 

On the 18th of September, I began to work on EGR after receiving the EGR Delete Kit.

 

The install of the plate was simple. Although, I believe I might have taken a bit too much off the manifold when using a Dremel to try and remove the caked on gasket. But that wont matter, because I will likely have to remove the Intake Manifold now...

 

I soaked the nut/bolt that holds the EGR pipe to the Exhaust Manifold several times in several de-locking treatments. The head still broke off because the piece is likely rust welded into the manifold. So now I need to manage that issue.

 

I am thinking of just going straight for headers and upgrading the exhaust system all together. Of course I am entertaining all thoughts and would love your feedback!

Headers and an N42 intake off a '75 or '76. Pre EGR.

Do you have any recommendations on headers?

 

I believe the L28 block has square shaped ports, but most headers seem to have circle shaped ports. Do you have any insight on that?

It'll depend on which head you have what shape the exhaust ports are.

Is there a way to find out without taking the exhaust manifold off to check?

Just in case your engine has been swapped with a later ZX motor or Frankensteined out of a later head/earlier block, look on the passenger side along the bottom of the head for the head identification..It'll likely be N47

There's a kit?

I sure wish there was! I read for hours before I figured mine out but it was worth it.

Maybe the block off plate and gasket? But there's a lot more to it than that if you do the hole $^!# and kaboodle.

Turns out I have diamond ports!

 

Any recommendations on aftermarket headers with diamond ports?
