Simon,

My motor is a pretty tame L28.  I would be looking for the 1 & 5/8" pipes.  Ceramic white.  Now that's 'old school', for an old man!!

As Benny said.
My PMC L30 has 10.5:1 comp and expected 300hp.
I'll be ordering 1 5/8".
More experienced guys can chime in. But bigger is not always better. If you put 1 3/4" on anything but a race prepped engine, it would be at the cost of low and mid range torque. They are made for high range RPM's.  ???

Simon
Chrome, Matt and gloss black are standard colours. White would cost extra, I'll find out how much.

well iv made 330hp with the 1.5/8 set from SW so you will need a hot donk to justify the big ones

Hey Simon,

I've just read my copy of "How to modify your Nissan and Datsun OHC engine" as suggested by Benny and it has made it clear that I would not want anything bigger than 1-5/8 inches primaries in the future (when I upgrade my motor performance), and probably 1-1/2 inch primaries would suit my current (stock) setup best. The 1-3/4 in is suited to racing engines.

Unless they give you the option of getting 1-5/8 inch or 1-1/2 inch primaries I'll have to pull out. Sorry mate :(

Cheers,

Stephen

In that case I will wait to hear whether or not the size can be selected before I commit. Cheers!

I've asked the question.

The part # we're after is -
99996-E1143  -6 into 2 race header for L-Series 6-cylinder, 1.625" primary diameter, unplated
Communication is not a strong point with these guys in Tennessee  ::)

And that might be the biggest issue :( I gave up years ago - ordered a LH and RH strut for my old 120Y got two LH - so I then got two RH and sold the second set. The last 2 sets of headers I got for a zed I imported from Japan - as I did not even try the USA boys as I heard getting the headers was like hens teeth.

Yes.
Ok, to save everyone wondering the same thing.

The real question is......
Will you see any performance gains?
No.
You will need to spend lots of money on engine mods to see the benefits.
Will it look da sh!t?
Yes.

I'm running dangerously close to walking away from this, due to the fudgetards that I'm trying to seal the deal with  >:(
If someone else wants to take over, I can pass on all my correspondance via email.

I might just go and get SWR headers..........

You will see a gain in HP from going from the stock manifold to headers on an L28. Noticable different when i did it on my L24.

the problem is even at 1 5/8 they are too big for a stock motor id be surprised if you gained 1HP infact from what I've read it will have a negative impact on the motor!!

What headers did you go to Jake?
What other mods did you do?

Yes. (It will fit a stock L28)

I stand by my previous statement.
That you will not see gains with a stock L24, L26 or L28.
To make these headers work properly, you need to spend close to $10k on engine mods!!

But they are purtty  ;D

They might be only 1 1/2" i havent measured them but all the car had was a CDI and a 2 1/4" system with a straight through muffler, oh and some hand tuned SUs  8) Stock as a rock pretty much. Definitely went faster by the ass dyno.

i have tested then and i dont like them .... as they dont make good torque in the mid rpm range

  I didnt want to say that so i just put dimensions and quoted big , but your bang on the money Pete , bog down mid range as the primary are too large in OD and length, might help using a 1. 7/8 inch exhaust pipe, sorta defeats the purpose a bit then, not a good street car or even a really good street car pipe, maybe those interested should do more homework on them its a lot of time setting them up properly

Just to reserect an old thread that had kind of died off.
I heard back, finally, and there still may be some hope for those interested.
Frustration would be an understatment with the clear lack of communication!
