Just out of curiosity does anyone have a completely built longblock?

I think esfourteen has one that could be built...

I meant has anyone done that kinda build sorry?

theres really not much to do to the head, it flows incredibly well

Did you fix this on the manifold and do you have any photos? What did they do? Yes, I have the same instance. It never affected performance or even made any noise whatsoever.

BTW: I had the off-the-shelf Wiseco 9:0/1 pistons. ANY discussion about lag or being soft at low and mid throttle from my standpoint is irrelevant. My tuner (Mike Botti) did his magic, and if anything it had more grunt than stock. Incredible. It's STILL a big honkin 3.7L V6. Don't overthink this area. Firsthand experience.

Thanks for that post. Let me know, please.

Yeah I never heard or noticed anything regarding this crack, my fear obviously is that it will get worse. The shops fabricator is doing the repair soon so I'll post photos when he's done. I know he has to heat the manifold to repair it properly but that's all I know at the moment.

yes i have a fully built GTM competition 4.2 stroker. should be shipped to me in Jan.

sometimes I get the feeling you don't understand how the internet works. you remind me of those parents on Facebook who comment on random pictures they see in their timeline and assume they are talking to their children for some reason.

Hey, How did you know that your head gasket is toasted? Sorry if you mentioned my answer already I tried to look but didn't find answer.

Yeah I would to know as well since I am following esfourteen with my build...:tup:

Usually an oil analysis finds coolant in your oil, or the coolant has oil in it.

Is this the motor you've claimed to have "had" for years now? And if you're waiting on GTM, January is a bit optimistic.....:rofl2:

it was pretty obvious from the rough idle and white smoke, you can tell you have issues before full failure like this if you find you're pushing coolant out of the overflow/expansion under higher boost. also you may find carbon build up in the overflow tank. looks loke black residue

Okay. I will watch my engine more often now then, thanks for info.

Glad your engine is healthy.

No thats the 3.7 that i sent to GTM 2 years ago . and he keep it for me till i need the build as i bought it in the states. he started the build in july of this years.
My other spare 3.7 got stolen from me up here in Canada.

Ok. Have you talked to Sam lately? I wouldn't be expecting anything from them in January.

for anyone interested, here is the driver side turbo bracket fabricated by RealAutoDynamics

http://scontent-b-lga.xx.fbcdn.net/h...88237102_n.jpg

This braces the turbo to the block, so the turbo is not just being supported by the manifold runner itself. The guy who made this knows his sh!t but we have no way of knowing 100% if this will prevent cracking long term, at the least it should prolong the life of the manifold. If this cracks again I'm switching to the shops custom manifolds (they have built their own TT kit which should be announced in 1-2 months).

Gtm should be fitting the bill for your cracked manifold.. Awesome fix will give them a call today...

^^^ That appears to be a good support. I'm in the same category with the hairline crack in the manifold. The thing is, I've yet to hear of it getting large enough to actually affect anything. No noise, no leaks, no worse. It's confined (in mine) to about a 3" area.

I am dead certain my manifold has glowed red several times in its lifetime. The expansion effect may play into this as much as support. This fix above will help.

I just sold my entire GTM kit within hours of listing it on MyG37 ($4k) I didn't hesitate to order a fresh manifold, though. No NEW buyer wants to have reservations, so I called, talked directly with Sam, and he cut me a deal, and shipped one out pronto. It's not free, yet my system didn't owe me a penny for what I've gotten out of it.

YMMV. I'm not a GTM hater, obviously. :)

I did have to pay for my manifold since it was outside of their 1 year warranty unfortunately, but I'm hopeful this will prevent the new one from cracking. Fortunately GTM has plenty of the old manifolds sitting around heh

small update, parts are back from swain tech and the engine should go back in within 2 weeks

I like those z1 motor mounts!!!

dat white lightning. had some delays but should be done within the next few days

Looking good nick!!! I think we will both be back up very soon... Also you need to ask the shop if they can open up those openings like I did on mine for more flow... They are undercut by 1/4"...

:tiphat: yep they took care of the manifolds and ported them to match the gasket. I still dont know if it will help given the small runners but it certainly cant hurt, we shall find out soon enough. I will definitely be re-tuning the car on e85 within the next 4-6 weeks.

For anyone curious, this is the support bracket RealAutoDynamics made for my driver side turbo. it's hard to see in the picture but its actually attached to 2 of the manifold studs and then to the front half of the turbo. Ideally this will prevent the cracking issue but it should at last prolong the life of the manifold.

Any chance of them making more of those? I'd buy a set to have on the shelf if my motor ever comes out.

And here is a shot of the new coolant source for the turbos. While there is a similar location on the passenger side turbo that could be used, both turbos are fed from this source as its the coldest source of coolant possible.

I can ask but I have a feeling the tech wont want to take this bracket off again, its quite a pain to get it installed with the turbo as you can imagine due to the tight clearances.

Cool, let them know there's definitely a small market of guys who would be interested, as well as for the rerouted water lines for the turbos. They might be able to make some coin if they had a kit to fix the couple of bad decisions GTM made with their kits.

I saw the bracket and rerouted water lines in person yesterday at R.A.D it's definitely nice :tup:

Do you think you'll make the 600 mark on those turbos on pump gas?

I made 575 dynojet @ 15psi peak, tapering to 13, so I'm confident it will do 600 on pump at 17. thats the plan before switching to e85 (before summer).

I called them 2 weeks ago regarding the bracket and someone was supposed to call me back but never did. The stage II turbos according to the specs maxed out with the .86 ar should be right at 360hp each x 2 =720 crank so I'm guessing around 630whp on 93 pump..

Anyone figure out a better way to reroute the water lines?

I just posted this on the previous page buuuuttt:

3/4" T fitting using existing port in the block, R.A.D. chose a T fitting from this single port because it provides the coldest source of coolant for the turbos.

you can see the feed for the passenger turbo comes from the driver side under the engine here

I believe both of the return lines route up to a single T in the passenger heater core line at the top, which you can see in this photo.

Hey GTM you might want to grab a pen and take notes!!!!!

I located the port n the block and decided to post a pic. Nice work esfourteen..
