New McXpress kit

I assume you are getting this direct from Sweden? How much is the new kit?

 

[ken_climb]

30,000 sec or $4000 US OR $5200 cdn .they claim 230-240 hp on pump gas.or approx 300 hp with race fuel or low compression pistons

 

[Buckeye]

230 to 240 HP?

At what boost are they making 230 to 240 HP? On pump gas? Does the kit include a new head gasket?

 

[Mountaintech]

What kind of turbo are they using in these new kits? Is it plain bearing or ball bearing, european or domestic?

 

[ken_climb]

They said the kit comes with a thicker head gasket.All i know about the turbo is that its a little bigger then last years version and i think its a mitsubishi.

 

[SUPERTUNER]

If it interests you, I distribute the Mcxpress turbo's and when I do an install in our shop or sell them for customer installs, I offer a custom made head gasket that is approximately double the stock gasket thickness and the center layer of this gasket is slightly thicker directly around the bore to act like a stainless steel o-ring with a copper gasket does on o-ringed mega compression engines.

www.easterncycleperf.com is my company website and has all the contact information there. If you are going to do this, you might as well do it right and not double up the stock gasket like McXpress suggests.

Head Gasket

Freddie is right. on't stack 2 stock head gaskets(6 layers). I used the gasket he is describing. I still would be concerned about getting 240 hp on pump gas. I would think anything over 10 #'s of boost is going to want better fuel, unless you are changing the pistons.

I thought it looked like the turbo off of my old talon. I think it was called a 14b.

 

[ken_climb]

Thanks I'll keep that gasket in mind .On my fax they sent they wrote 130 -140-hp on pump gas at 7#but on the phone I'm sure he said at 10#.Iguess i'll just have to wait and see.

 

[Buckeye]

I guess my question is if you are pressurizing the carbs to 10 #'s what difference does it make which turbo you are using? The only difference I can see is a little lag with the rear turbo because of the distance. I know the first kit makes 218 hp at 10 #'s. I believe Bender's makes 220 at 10 #'s. The difference there could be the dyno. I would like to see more info on this new version.

 

[ken_climb]

does bender lower there compression as well?

 

[Buckeye]

compression

I don't believe they do. But they want you to use race fuel with the stage 2 kit(220 hp). MXZ900 could answer this.

 

[POWERHAULIC]

No Bender kit doesn't lower the compression. Power at 8lb. is 220, a blend of 100 octane with pump premium is recommended at that level. Although there were several RX1's last winter running around with 8++lb. on pump fuel, no probs.

 

[TURBO TIME]

not only will it have more lag being mounted in the back, the larger turbo will not spool up as fast as the smaller one.
