As far as i know the DJ header is a exact Nismo copy, ask Jarman.

True for the LHD version. The RHD drive version is Dave's own design and looks promising. He's not in production yet and just got his web sites up and running. FYI... he has a long Nissan racing history especially in Super Touring:

Hi Rick,

I believe the Clifford header is the same as the Datsun Comp header mentioned by Conedodger in post #2 above. Here is an old thread that discusses them http://www.classiczcars.com/forums/showthread.php?t=32243. -Mike

Same here, Mike, great to meet you and to talk to you in person. That

was probably the highlight of the Convention/Show for me, meeting you

and several others who had previously just been names in print on a screen.

Now I know y'all are REAL PEOPLE! LOLLOL

I flipped over to the reference you provided, and sho' nuff, that looks to be

the same critter. I had forgotten whether it had been in the Bob Sharp or

the Comp Dept catalogue, or whether we just got it directly from Clifford.

Being with Sharp at the time, it could have been any of those. BTW the

downside of the over-and-under arrangement at the rear is that if your car

is lowered at all, it is easy to find places to scuff the lower extension.

Don't read any farther unless you are very brave; this is going to KILL you!

I just looked into the file on the '70 car. In Apr 76 (at my price) the whole

system cost me right at $250 installed!

It sounds dirt cheap now, but it was about 2 weeks' pay at the time!

FWIW,.............All Z Best,...................Kathy & Rick

Rick, is it because you just get bored??????

Bear in mind, that the header should be tailored to a specific engine spec, and as the original poster has a 2.4, (and stock?) a couple suggested could have too large primaries, and could/will loose horsepower. e.g. 1 3/4" far too big.
