Tomei headers

Pipe wise they use a 42.7mm primary and a 60mm collector flange
As for equal length vs non, there are plusses and minusses to each design - all depends on the cam you intend to mate it with and the power band you want

I plan to install cams & headers... I was set on making certain they are equal length headers - but now this post make me question?...
If I'm considering a mild cam (streetable performance with occasional track) with tune (including cam timing) - and my goal is as much useable power as possible (I realize cams generally give up a little down low, for gains mid and top) - what headers would you suggest? And what cams for that matter?
I'm considering Crawford (but if a less expensive and easier to install option is out there please inform) - and JWT cams
Your suggestions please. TIA
Nismo/Crawford for headers
lots of cam choices for non-revups--me likes Tomei and the new HKS cams look interesting.
I'm sure Adam can give a much better opinion and recommendation on the cams tho!

personally, I wouldn't bother going through the time and expense of fitting cams without fully building the motor (heads to block) - I just don't think the gains are worth the cost otherwise

Now, cost vs benefit is a whole other story… really there is no viable cost/benefit N/A approach. I like the challenge of having one of the fastest N/A daily drivers – especially AT sedan.
It will be an expensive “lets see” project… but one that I am becoming more certain I will try.
As it stands I will likely use Crawford headers and JWT S2 cams… I am not anywhere near finished researching though…
If i had it to do over again... I would of went with Crawford headers.. Right now i have DCsport headers.. The reason i went with these is because they were listed incorrectly on a website over 3 years ago and i paid $300 and some for them.
As far as cams... Im still researching that for myself as well..

Most people balk at the Crawford price and install - and indeed it is a factor - but to determine gains, I figure might as well do all or nothing.

It's easy to go FI - but it's not easy to be one of the fastest FI (since it's so common)... It's a challenge to find power N/A - and there are fewer that have spent the time and expense - so in some respects it's more rewarding to me...
If I was only doing it to have a faster car in general, I would have bought another car all together (still might)...
