R56 My full engine built will be here.
For some reason, I'm thinking the open were the downpipe connects is much bigger. But I don't have the original one in front of me too compare them.
Yea, it's gonna a bigger downpipe for sure.
So there ya go folks. I'm willing, and have the time to save the money to add the bigger downpipe. Everything you do has a trickle down theory. Ya get this. Ya need that. Then that needs this. It all basically adds up to, how much you willing to spend and how far you wanna go. If you don't have, forged pistons, aftermarket rods. Why bother with the big stuff like I did. The ko3/ko4 hybrid or jcw turbo will get you were you need to be.

If the inside diameter matches the inside diameter of the downpipe gasket gasket then it is bigger at 2.7" instead of the normal 2.5". I know the DP Mario sells is already ported to match a 2.7 diameter turbine exit. I believe ATP also sells a 3" DP to match a 3" exhaust if your still thinking about going that way. Not having seen one though I don't know if the top is 2.5" or 2.7".

Hey Sprint car is it a 360 ok a 410 I have a 110 Offy I want to put in my wife's clubbie with Hilborns and have the stacks through the hood like the old days. Can you imagine 4 Hilborn injector stacks running left to right across the hood.
It is pretty! Thanks for the show guys! Even for the pound price, one would like to think they could find a way to handle the shipping. 1700 dollars would seem reasonable and doable but almost doubling that on the exchange rate puts it kinda out of sight for us mere mortals. Can't wait now to find out how it performs, especially with your build Sprintcars!


Why don't you boys just grow up and act like civilized men instead of immature boys.

When it shows up please post a couple of pics. I'd love to see the build quality. As far as I know it's the only 3" currently made for mating to a Borg Warner turbine housing on the Cooper.
Ok tigger. No problem. That was the reason I went that way. It was already used for the Owens turbo and the guys at eurotek highly recommended it. So certain things you don't second guess when someone has experience with them. Thumbs up jerry
Do you think you would ever do a motor for another NAM member after gaining all this experience from doing yours? I just had fitted the ATP 3" DP from JMTC this week.
It took a lot of fabricating incl cutting the pipe in 1/2 down low so the 90 elbow would match up with the rest of the exhaust.

Agreed and understood. I did automotive machining years ago. Its a slippery slope for sure but if you've been down that road before one knows what they r getting into.
Perhaps a list of vendors/contacts and what specifically was used? I need to do a N14 motor for my mostly track car. I want to port but have zero experience with these heads. If u were closer I would do your Manic tune for you. Too bad.

The exchange rate works both ways, keep that QE coming I need to buy a few more things
