Let me guess, Trick Parts?

Now we've got a race on our hands, Mark! I'm trying to get off my lazy rear and get to the dyno so I can be the first person on this forum to post a 200+ RWHP dyno sheet.

Oh man, I'm not sure. If so, it was before I joined this crazy bunch. If that's true, I'll just have to modify my claim...First red 311 in Portland to post a 200+ Hp dyno sheet on the 3rd thursday of a month with 7 days of rain..... 
If someone beat me too it, that cool. More power to 'em.
Yeah, a dead stock DET should be right around 185 at the wheels. I pulled 176 but was only running 6 pounds of boost (old worn out wastegate spring). Stock is 7. I have the Profec B turned up to 11 pounds. That should be good for well over 200.

Hey Sid,
I would have no issue with Mazda or Ford for the swap, I just don't wanna do any cutting and want the "easiest" route to get there. I think the only thing here in OZ (not with the wizard by the way) would be that "hot up" bits are more available for the Mazdas.
Cheers,
Stuart

I've been following Sedlack's project. Awesome. The guy can fab anything it seems.
You might want to check, but his horsepower reading for his V6 Cheby was off of Desktop Dyno, not an actual dyno, unless I missed something.

and, Checker was unable to get me a water pump. I waited a week and paid them up front for a special order off of the Beck and Arnley part numbers we have on this site. No longer available. Oh well.....

Hey guys, chiming on on the later Miata stuff being dimensionally the same and the answer is as far as my conversion goes, yes. The base engine block is still the BP derivative, but now with VICS variable intake cam timing, and the tranny I used is a 6 speed which is currently available in the current LS model Miatas.
I am now waiting for the body to be final painted and clearcoated.
I have some other nice mods to show off using the stock senders for the Datsun gauges on the Miata motor. Check the cardomain site in coming weeks.
Another mod we just completed was a tucked in battery relocation to the trunk in a stainless steel box using a Yuasa Goldwing battery with the same Ah and CCA rating as the Miata battery. It is AGP based and safe and fits down inside the passenger trunk well behind the rear wheel, preserving trunk space. I will have shots of this as well. PM me if you are interested in theis conversion and I can shoot you the Yuasa part numbers.

Alvin,
No muscle car stuff here man. The turndown is just temporary as we were waiting to have the body back on for final fitment of the over-axle pipe and rear muffler and heat shields. Have to know the exact gas tank location for clearance and safety issues.
Thanks for the support!

Dyno Numbers

Wade,
How long until we get to see some dyno numbers for your swap. Would be interesting to see, especially with all of the recent debate going on in the general discussion section.
Are there any upgrades you are thinking about adding for big hp increases, or are you going to enjoy the car for awhile before tearing it apart again?
John...

Guys,
I have 1 good chassis dyno here in Louisville. I expect to be on it by August at the earliest. Remember this is a full nut and bolt resto, so we still have a little ways to go to wrap up (trim and finishing). The engine package is now set to include an Eaton MP62 (BRP-based) supercharger running 7PSI of boost to the blow-through Weber setup. This is old-school fuel management, so guys save the comments about stand-alone FMU's, etc. Fuel pressure regulation is via a NOS/Holley 0-12PSI boost referenced fuel pressure regulator, fuel pump is a Carter rotor-vane with 18PSI max delivery pressure at 100GPH, compressor bypass valve is manifold referenced and location is right under the air-box on the Webers. BRP is getting 200 FWHP out of similat setups. I am not going to push past 7 or so PSI to limit the need for a air-to-air IC and more sophisticated timing controls.
That is the plan for now.
