I so want these, I'll have the money for them in two months ....
... and this might help people understand how headers work, http://www.motoiq.com/magazine_artic...rk-part-1.aspx

Come on people , unless you want to spend 10g's r and d'ing your own get these.

 

so that's two now?

 

 

I have a set of these incoming second week of March.

Will post pics if anyone is interested.

 

... and maybe vids and dyno's?

 

That car sounded excellent.

 

Wonder if these are better than the ppe long tube headers

 

Minimal at best

 

King are you getting them?

 

If 18 others sign up for them in a group buy bringing them down to 1200-1400...then maybe...

Other than that, NO!

Only so many ways to design equal length headers because each design will still be equal length! I think my PPE will hold me over, again if this was pushed three years ago though I'd be all over them.

 

And you know this how?

 

I don't know?

 

from what Sasha said before in his thread, he found 13whp from going with larger pipe but sacrified the lower end power..

there werent PPE header but similar type of header
the stepped PPE are 1 5/8'' to 1 3/4'' , the transition on my set start at 2 1/8''

the production SGM header are 1 3/4'' to 1 7/8'' the transition if I remember correctly was 2 1/4 to 2 1/2

so, right there a good cam will make more jam from mid to high RPM than the PPE header if the whole setup is sized properly ( intake size & the rest of the exhaust.)

the 13whps from the Sasha's finding looks very plausibe.

 

If you have post the thread 6 weeks ago. I would have purchase these. I already order a set of PPE lth, and still waiting to be delivered. I will test out the PPE and hopefully will jump onto SG lth setup in future.

 

he started the thread on 01-24-2013
thats a bit more than 6 weeks

 

Yes, I was doing research on PPE lth at that time as well. When I was told PPE will mark up the price to $1,300 early of 2013, I have to hurry up placing the order to get the lower price. The group buy people were so lucky to buy the PPE for a steal price.

Since PPE has raised their price to $1,300, which might help some people to consider to buy the SG lth for the quality and extra gain in performace for track or extreme NA setup. Personally, I would buy the SG lth over PPE even though the price different $2,200 vs 1,300 is $900.

 

Agreed.

My first set of SG Motorsport headers should be done before months end. Will post pics.

 

If SG had theirs a tad under 2K I would be on them like hepatitis on Pamela Anderson

 

Was your PPE set were design for the HR, DE or RevUp? Because PPE website provided 1 3/4 straight to merge collectors 2 1/4 transitions to 2 1/2. I do not see the info for the stepped HR design spec. If the stepped are step from 1 3/4 to 1 7/8, that would make very close to the SGM Sasha lth design.

I have been followed SGM Sasha built NA VQ35DE for sometime. From what I remember, Sasha was running really huge and extreme CAMS design by JWT, a very well respect company in Nissan community. The CAMS were C9 with approximately 13mm of lift on both intake and exhaust. That is how Sasha able to force more air in the intake and breath more out from the exhaust to extract more power. Sasha did even try the C10 cams on exhaust side, but they did not improve power, so he kept the C9. The SGM lth were design to channel exhaust gas from those huge cams to make that incredible 372 whp seconds behind Fontana 350Z with 470 whp. So, i have no doubt SGM Sasha lth design and flow better than PPE lth for the HR in term of performance.

 

I agreed your first point. The second point about hepatitis on Pam is funny, LOL. But which hepatitis will you be, A, B or C? LOL.

$1,800-$2,000 for SGM LTH, more people would be draw in interested.
