Everything done, my motor Will ship tomorrow. Listen guys I'm not sure if I'm going to be able to help out with those gtm manifolds. Vsr is very busy and there is no telling when I may get them back. By the time they get my manifolds and figure out something or fabricate another set it will just be way too long for me to wait and I really want to get my car up and running again. Plus I refuse to be the guinea pig on a new set of manifolds and possibly be forced to do this all again. Sorry guys but I want my car up and going..

So you're gonna reinstall the cracked manifolds?

faceglide · 03-20-2014, 09:52 PM

I think hes going to get them welded and cryo'd?

I am not surprised that they are swamped, its about that time to get those last mods in methinks.

tubular manifolds love to crack unless they are really high grade stuff, like welded iwth the pipes back flushed with shield gas using the proper rod with all the same grade of stianless for the parts (at the very least 304 or better). the head flange needs to have all the runners divorced so it can move around as it heats and the wall on the tube needs to be thick enough to fully support the turbo under these conditions. also it is going to dump more heat into the engine bay in a very tight area next to a bunch of stuff that doesn't like to get hot. This is why sets for the 350z cost upwards of $1600. Just throwing that out there.

How do you know all this?

1slow370 · 03-21-2014, 12:10 AM

I know everything muhahaha now seriously, welding courses, manufacturing engineering, machining, autorepair, and a decade of experience. Knowing people helps too, as well as a serious passion for all things mechanical. Designed and built my first sc kit at 16 lol

I posted up info about using a restrictor to fix the coolant line issue but cosmo had it deleted

Do you know a company that can make us a manifold for GTM replacement that you can hook us up with?

COSMO · 03-21-2014, 06:18 AM

Yeah that guy knows it all and is often a prick here on the forum. I highly suggest starting a new thread on making after-market gtm manifolds so we stay on subject here. Do not start any crap on my thread 1slow370 as you have done before. Oh and before you listen to what this guy has to say keep in mind he was trying to tell Charles how to make a fuel return system and got owned....

COSMO · 03-21-2014, 06:55 AM

What I'm going to do is have them x-rayed to see if the crack is superficial or not and then have then welded. Just from looking at them it seems the cracks are superficial because you can't see any light through the inside. Understand people this process of making entirely new manifolds to replace the gtm one's will take a lot of time and r&d to do it right and I don't have that amount of time to again wait to get my car up and going again.

Yeah, if there's any way to patch up what you've got and get back on the road you need to do it. Another few months without boost and we're going to have to put you on suicide watch.

Get the car back on the road and we'll figure out who wants to go into business making replacement manifolds later.

Plus the king mackerel are starting to come in and snapper season isn't too far behind that!!! Anyone like deep sea fishing here? Been working on my boat the past 2 weeks getting it ready for the summer but I NEED MY BOOST!!!!!

Chuck33079 · 03-21-2014, 07:16 AM

Yeah, do whatever's necessary to patch up the manifolds and hammer out the rest of the car. You're what, 30 days from 600whp or so? No sense in dragging it out unless its absolutely necessary.

Dad started me king fishing when I was like three years old. Nothing like the feel of that first run. We took a neighbor one time and when the king took off he tried to slow him down by placing his thumb on the spool. Hard lesson that deep sea fishing is not bass fishing.

Yeah man I'm dying to get back on the water...
