Since the diesel bug has gotten me and its getting worse. I've been finding its hard to do one mod and test it.


How much does porting the manifold/ exhaust housing lower egts?.


I would of been able to figure this out, but I hadda take the whole turbo off to put my gds wheel/ compressor housing on. The center section wouldnt come off the exhaust housing. Got tired of screwing with it and removed the whole turbo instead. That lead to me tearing the exhaust manifold off too.


I ported the housing yesterday and spent 2 hours on the manifold tonite. The truck should run better


Why im doing this? Dunno..... Truck sits in the driveway.....

 

Because you can.

 

I personally thought it was because im sick in the head

 

i ported my mainifold today, and wow.

my main goal was to drop cruise boost. which it did, i went from runnin 10psi at 65 to 6-7 psi. which is good. then i gained top end boost, i had my w/g set at 35-37psi to open and when i changed the mainifold i let that alone and now i'm running 42psi, which i do not like so i will have to adjust that.
I also moved my pyro probe to pre turbo from post and wow that gauge moves fast.
pictures to come

 

You've had your probe post turbo this whole time

 

yes and the pistions looked fine on the old engine, goiing to do some more testing today.

 

ive ported several exhuast manifolds, surprised how far they overlap the port. plus heat makes em move to. well worth the effort.

 

im always looking for new cheap mods and this is definitly something i am interested in any pictures. also what did you port them with? also did you ahve any problems with lining the manifold up again? i know they shrink

Pictures please

 

die grinder, carbide bit.trace the gasket. make it smooth. dont take to much. hold manifold to head. look close at how everything matches up. ive never had one leak. i always use new gaskets.

 

Did you just do a gasket match porting, or did you do more? Did you do the turbo mounting flange also?

 

 

ohhhhhhh crazy matt....

You ported an already aftermarket manifold... cheater.

we're trying to avoid buying a $450 manifold

 

alwaysworking you got any pics? cuz i would really like to see those also how did you get them off was it hard any info would be great

 

pictures might not tell to much but here they are.

i pulled the turbo and the loosend the heater lines and droped the down pipe lose then got the air gun and wobbly and zipped it off.

 

i did the exhaust housing when i installed it but now it needs more.
