DCR Still Here
 

Just wanted to give everyone a heads up. DCR Is still building and maching new parts for the MS3. We did not leave. We are about to ship out the first 5 turbo manifold we sold. So guys be on the look out for all of the new DCR MS3 Performance Parts & Complete Engines.

Later, Nubs @ DCR

Please pm us or call us @ 1-276-956-2082 if you have any questions about the DCR MS3 Products & Pricing.

Thanks, Nubs @ DCR

...any sort of timeline on completion?

Yeah, I periodically check the DCR site everday, hoping and dreaming, of a p n p'd head, upgraded valves for 8000rpm, and cams.... someday

Re: DCR Still Here
 

Can't wait for mine

Ditto, eagerly waiting for my manifold.

I'd like to thank DCR for not shipping them until they were 100% happy with the quality. It means alot to me, the customer.

The stock valves are good to 8500rpm, cams and pnp heads are already available. :drive:

Welcome back. Hope you guys do well on our platform.

Thank you for still being here lawl :)

good news indeed.

When and where is this info, directly posted on a company site? Still would be better to have a PnP'd head with built block from one source, rather than head from shop x and then the block from shop y.

This week?

read this thread. your boy 06speed6 has done a lot of research for us: http://www.mazdaspeedforums.org/foru...e-heads-22129/

welcome back, and thank god u dropped the dead weight!!!

+1, welcome back, hope you stay for long time and help us with this platform. :javanc:

Not really considering DCR has contacted me for vendorship...

Yes I know of his hard work with regards to that thread. I PM'd 06Speed about it - all I'm saying is it would be nice to have a complete package setup, idk I have atleast 6 parts from different manufactures on my car and only made 284hp with stock K04. I am pretty positive that 99.9999% a Exhaust Mani+DP+PnP'd head from the same company would achieve greater results.

I believe PG, PTP, SU, and P3 can all build bottom ends and p&p heads. To my knowledge, only PTP and PG offer cams.

DCR should have a built bottom end sometime soon since they have been developing it for 4 months or so now, I havent heard of a p&p head or cams yet.

lolz

Same here... but now that my motor blew and I got lucky with the warranty... might not be putting the mani on my car when it finally arrives...

PM jmhinkle, i bet he'll make you a dandy offer on it.

So the lets address the BIG question. Have you guys figured out exactly which part, or combination of parts is making our motors blow with minimal mods? Or are you just going to sell turbo kits that blow the motors and then we have to come back to you and spend $5000+ on a forged setup?

this is a good thread...:35:

I don't think our blowing motors are DCR's priority. And honestly, a turbo kit is probably one of the best things you can do to save your motor.

i think it's GREAT DCR is working with the Speed3.....
and for what it;s worth anyone can say what they want about Randy......but i enjoyed his time here and his enthusiasm....we all have our faults,,,especially me....

Okay, you stick with your peak torque and full boost at 1800rpm with stoich afr's and 50 degrees of spark advance...

and i'll stick with my 3071 with cooler efficient charge temps, full boost at 4000rpm on 20psi, afr's in mid 11's, and reduced reversion from reduced exh mani back pressure (cleaner valves)...

and we'll see who's safer.

you are beating him with a truth stick:smokin:

still waiting... what kind of numbers we talk about? safety? did robbie's car ever run at the track?

That's fine, come back and PM me when you blow up. I'll be on the stock turbo with a couple of bolt-on's. If anyone is flooring their car under 1800 RPM's with the execption of 1st gear, they should blow up. BTW, shouldn't a 3071 spool way sooner than 4000RPM? I don't know how they respond on the Mazda engine, but my SRT spooled a 3076R around that.

flooring it with a stock turbo at 1800rpm would be no different than taking that 3071 ALL the way to redline. (creep ftw too !)

They would both be really fucking stupid to do.

you guys are crazy, id choose a big turbo over the stock for safety anyday, people just have it in their heads that they think oo thats a big turbo its guna blow my motor, you could have a gt42r but since u cant make past a certain hp anyway how is it guna blow you up?

Jesus people, look at this thread

http://www.mazdaspeedforums.org/foru...e-thread-6113/

I know we will never have hard numbers, but if we took the percentage of aftermarket turbo/manifold guys that blew up vs the total number of aftermarket turbo/manifold guys. Then compare that to the stock guys who blew up vs the total number of stock Speeds, the results would speak for themselves. You would have a better chance of blowing up with an aftermarket manifold and turbo.

There is a known fact there are weak components in the shortblock. So you could blow it up a few different ways. Please don't tell me that a big turbo isn't one of them, unless your just trying to convince yourself so you can buy one and slap it on your car. If that's the case, I agree, a big turbo is better and you have less of a chance of blowing up. :headbang:

Hahaha, seriously. Don't forget what blows a motor up. Detonation, high BAT's, overly aggressive spark advance, bad oiling, heat, etc etc.

Please explain to me how a properly sized turbo increases any of those risks? It doesn't. IMO a BT is the "right sized" turbo for this car.

If your going to use a stock turbo, please adjust your boost curve to limit boost before 3000rpm, and keep the closed throttle near redline.


Oh and my spooling problem & creep issue will both be fixed very very soon with the DCR exh mani.


And here's a beer rap i made tonight:
DCR

The only parts that have been proven to be weak are the pistons, and they are good for quite a bit of power. This has also been said by DCR.

The IM needs to be flow matched and the int and exh runners need to be flow matched due to the EGR significantly hurting flow on cyl #1. The boost needs to be in the efficiency range of the turbo (stock for stock turbos), and optionally the pcv system needs to be gutted and completely reworked.

Notice I didnt mention any work on the stock bottom end or combustion chamber.

Re: DCR Still Here
 

So how much power are the pistons good for? Curious to see how close I am.

i think that mazda is counting on the cooling effect of the di too much

Just go give everyone an update check out our website at Darrell Cox Racing (Powered by CubeCart) we have some of our new DCR MS3 Products up on the site. Check it out if you have any questions just give us a call at the shop at 1-276-956-2082

Thanks, Nubs @ DCR

Dude, not to be a dick but you need to get a professional web designer to fix you up a nice webpage.
