Our tube headers for the PL510-VG30 conversion are custom built exclusively for us by one of the best header builders in the country. We were very careful selecting a shop to build our headers, as we wanted to be absolutely sure they would be of the same high quality as the rest of our components. Our headers are built with 1 1/2" mandrel bent steel tubing. They were designed so each primary tube is one piece so there are no welds in the middle of the tubes to crack. The plates that mount to your heads are 3/8" steel and are surfaced after welding so stock gaskets (Nissan P/N 14037-V5000) will seal our headers very effectively. The collectors are 2 1/2" diameter and are quite smooth. The collectors end with a formed ball that fits into a matching socket on the reducer that requires no gasket, allows a lot of angular misalignment, and will not leak. The collectors are clamped to the reducers with two large bolts and formed steel flanges. Our headers come with header bolts for use at the heads, bolts for the reducers, one blank reducer, and one reducer with a fitting for your O2 sensor. You can install the reducer with the O2 sensor fitting on either header and it can be rotated 360 degrees to allow maximum flexibility of sensor location. Additionally, we offer Cermachrome polished ceramic header coating. Our coated headers are media blasted inside and out, coated inside and out, baked at high temperature, and polished to a high luster resembling polished aluminum. Cermachrome reduces under-hood temperature, increases exhaust flow, greatly increases header longevity, and looks amazing for a very long time. Cermachrome will not heat discolor like chrome plating and as long as it isn't scratched through it completely eliminates rust. If you order our headers without coating, they are shipped to you bare steel so you can paint, coat, or plate them to suit your taste. Our headers are tucked very closely to the engine and bell housing and will likely fit many non-510 VG swaps as well.

$350 for the set, but you would need to make your own Y pipe. Still, thats a hell of a deal compared to Thorleys.. and probably better made!!

I'd be interested to see how close these come to the driveline and other parts under the truck. Might be a possibility though.

Datz, how about that oil pan, do you think it doesn't hang as low as the hardbody/pathfinder oil pan?

Its a lot higher than the stock pan. On the 510, you have to cut about 3-4" off the bottom of the pan to make it work. The only issue is that the sump sits further forward than the 4wd pans.

I see. Thanks a lot.

Is the starter in the same place on the 300zx and 200sx trannys? If not, could be a problem cause Im sure those arent built around truck trannys.

another thing: 3 into one vs the "tri-y" (acually dual y here) on the thorleys?

just an observation, I have no idea if it makes a difference.

BTW, I saw those up close at the shasta meet several years ago. Very nicely built...


Ben

The starter is in the same place on all VG30e/i engines. The v6 200sx uses a normal v6 tranny, afaik.

Those are very nice looking headers. Had they used equal-length runners they would be even better, however, then they'd cost as much as the Thorley design (wish those bastages would make some for the '96-'97 KA24E, 4x4 KCs!).

Anyone know if those will fit the Vg33 as well?

good to know

after i finnaly got my pacesetter's to fit, i found them to be pretty nice. they are actual longtubes. the thorleys are shorty's.
when i take em off again when i swap in a newer 3.0 i have i am going to use the old style header wrap. they let out SOOO much heat.

Summit sells thorleys for $329. for the d21 v6

summit

Still 329

Broken link.

Summit Part Number: DTE-464-2

Is that the cheapest price for Thorley Headers?

AC sells them for $374.95

Stan

Still $329 at summit. I fixed the link.

These look real nice. I only bought the Pace setters because got them for $100 new.
