Opinion on the Strup or Stillen Headers I'm getting.
 

Ok, I have already ordered my Unichip and am gonna decide between Stillen and Strup headers tonight.

My questions is, what do I stand to gain (Torque-wise) from getting these two installed (meaning the Unichip and the headers)?

Thanks,

Jeff

P.S. - I already have the Motorsyne 1/2" Isothermal spacer, Pop Charger, Crawford cats, z-tube and Borla exhaust.

I would get the Strups... I am still waiting on mine to arrive, but they seem to be built very nice. I believe people have been seeing 15rwhp/rwtq and maybe a little more(I want to go on the low side) So with a decent tune I would expect you to gain more. I have no idea what G35's pick up with tunes so I cannot comment on power gains from a tune.

if you can get me the runner lenghts, diameter and variation in runner lengths on the headers and what your current/future mods are and i'll tell you what you'll want

Well, I wish I knew where to get the measurements. I've decided to go with the Stillen Ceramic headers, only because I can get them in town at Grubbs. Strup appears to be in a back order situation right now.

So, Stillen headers and the Unichip.

Anyway, I'm sure I'll notice a difference. Just not sure how much.

The good news is......my header install is being done for $178 by a former tech at Park Place Porsche here in Dallas. The guy is a stud and opened up his own shop here in Rockwall, Texas. Since he replaced one of my dad's turbos on his 2002 911 Turbo, I figured he's probably worth giving a shot with my G35 Coupe :) He's also getting me the Unichip and installing and tuning for $680.

I feel like I'm getting a pretty good deal overall.
