I'll take your word for it .

 

I have the stock h1c with a 12cm housing would that work the same as the hx35 in this setup?

 

Probably somewhat similar to it, Bill. I can't recall compressor wheel sizes on both the hx-35 and h1c but I think they're within 1-2mm of each other.

 

What size injector are you going to run with this setup?

 

Stock H1C is 54mm VS hx35 is 56mm.

 

6x0.020"......



Just kidding, Ihave my stock non ic'd set along with the 7x.010's I currently run. They are a sac type nozzle, manufactured by Nippodenso, with a 158* cone angle. So far I like them.

 

Hate to see such nice work with that crappy, restrictive factory exhaust manifold. It's too bad the nice aftermarket manifold are so expensive!
Can't wait for the run report!

 

If it is out of the truck on the bench, is there any reason not to do some blending / gasket matching? Would that extra work be worthwhile? Do the aftermarket parts flow that much better against a stock or blended factory manifold?

 

where you considering using this set up to vacuum the shop floor?

J/K. had to call you on your convoluted

 

yes port matching and porting the manifold are worth it if you plan to be over 400hp.and it may even help a little in low hp applications.

its an air pump the more it flows always better but porting exhaust when the intake sucks.........kind of a lost cause....another story for a naturally aspirated gas engine


in my opinion hardly worth the effort ,make up the hp with more turbo/fuel or

 

That manifold is only for mock up. I will be using a non-egr stock manifold for the final mount. I have ran both stock, 3 piece, and my own built manifold. Couldnt tell much between them all. You'd be suprised what a stock manifold will do. We ported one and I cut the angled flange off and welded a straight t4 flange on for a friend. Its got an s478 hanging off it.

I may do a little, it doesn't take all that long. To really get to porting it takes a bit, but the head is still the restriction.
Actually that stuff is made by Spectre, I got it as payment for a few finishing touches (welding) on a friends pre-runner before the upcoming race in Nevada. It extends to about 40" and collapses evenly and easily. Also got the filter from him. The tubing is pretty sweet in all honesty.
I would take a stock manifold over 400hp...actually, I have

 

Thanks for the pics!!! Looking great...keep us updated!

Got rid of the 5 inch outlet on the 55, welded on a 4 incher. Much easier to fit the downpipe this way.




Should make a little progress tomorrow, oil drains and feeds. Can't really do much else until they are in the truck.

 

Is that braze or weld?

 

Weld, 309 ss I believe? Could be 308. I could check if you'd like.
