I've heard of spraying a head gasket with copper spray.  Is there a greater benefit to using a solid copper head gasket?

Fontana Nissan 350z Build

Fontana Nissan Racing put up some pics and text of the build of their Grand Am/Time Attack 350Z. It includes the build of their engine which includes a Cosworth 3.8L VQ35 stroker. For the link to their blog, check out my left navigation bar (I feel lazy today). Click here for the FONTANA NISSAN RACING TECHNICAL CORNER.

Cosworth EC Pro Development

 

These last couple of weeks Ben, an engineer from Pi Research/Pectel, and I have been living and breathing 2008 Subaru Impreza STi. The Cosworth EC Pro is designed by the brains at Pectel UK (a division of Pi Research and sister company of Cosworth) for Cosworth. It is exclusively sale and use in the North American market so all you guys in Europe will not be able to purchase or use it (for now at least). There are enough differences between the European market STis and North American STis to make it a very impractical adaptation. For you Americans though, you will soon have the absolute most powerful plug-in ECU available in the...

VQ Crazy

 

Recently all around me have been Nissan VQs. There's the Cosworth Castrol Top Shop engine that I have been coordinating and tuning at Cosworth, then over at XS they are building a Z33 for my buddy Andy who owns Ark Design, so as a I built that engine on my own time, then I have been writing reports at Cosworth on VQ35DE camshafts like a madman, then I have been working on the Cosworth VQ35 long stroke crankshaft, my daily driver Maxima has a VQ30, I've been driving my mom's G35 which has a VQ35, etc. VQs kick ass.

 

The Cosworth Top Shop engine made 4xxbhp (buy the magazines) normally aspirated which impressed me. Th...

RB26DETT Valve Springs

Since the BNR32/33/34 Skyline GT-Rs were only really available in Japan and a couple other parts of the world, previously you only really had the JDM engine parts to choose from. Now that I work at Cosworth, I hope to change that. Although we are buried with all kinds of other work, I try to squeak out RB26 parts when I can. So far I've managed to help crank out new con rods, bearings, head gaskets, and now valve springs (more coming soon!). It takes a bit to convincing to get the OK to design RB26 parts. The RB26 is now an old engine and we are only designing parts for the RB because it has such a huge following worldwide.

Having measured and analyzed nearly every Japanese ca...

Should You Change Your SR20DET Head Gasket?

SR20DET swaps in S13/14 240SX's are quite popular here in America. One of the questions I frequently get is, "Do you think I should change my head gasket before I swap the SR in?" I always recommend changing it because it's fairly easy when the engine is sitting on a stand or even on the floor (don't crush the steel pan people!). The paper gasket is fine for 205hp and probably even ok for 280hp, but in reality it's detonation that usually destroys the stock paper head gasket. Since there are so many cheap asses that use the OEM ECUs on 91 octane in the SR20 swap world, it's even more reason to change the head gasket. Yes, the stock ECU can handle 91 octane because it can default to ...
