Suggestions for a new intake manifold, high performance motor mounts, torque dampener

[Turbo Eclipse]

I have a 2000 eclipse GS 2.4L with a 5431 Precision turbo pushing 18PSI and I keep snapping stock manifolds in half at the neck do to much torque.. I've been looking forever for an after market intake manifold that will fit the car. I've found some from edle Brock that say they are unversal on thier site http://www.edelbrock.com/. Also how many motor mounts would I need and which ones?
Thanks in advance!

I'm also trying to find a torque dampener to fit the 4G64 engine. I can only seem to find them for the V6.

I remember reading about the damper. You ah e to frankenstein a damper from the v6 one and the Evo one.

Well evo intake manifolds bolt directly on so try one of them

That would be a bad idea. They may bolt on but the 4g64 intake ports are much smaller than the Evo 8 intake manifold ports, much smaller and a port and polish won't even remotely fix that.

swap an evo/ptima head. you get a higher flowing head, larger throttle body, and higher flowing aluminum intake manifold.

Boost it or be slow.

My suggestion would be to get motor mounts and replace your suspension bushings. Not sure what your suspension is but if its stock get some coilovers or a aftermarket spring and strut combo

Hey guys, I have found OEM has just made a brand new intake with a re-enforced flange. Just got it in today and I'm going to install it Saturday and see how it goes. By the way I am boosted I was running 18PSI and I have after market coil overs. I won't be able to lift my engine for the mounts for a while so I also ordered an ingalls torque damper. Thanks for the info guys. Ill post pictures and progress.

What do you mean by OEM? Did you mean to put something different company wise or are you saying you got another factory intake manifold with a reinforced flange?

If you truly want an intake manifold to perform and benefit your turbocharged 4g64, I say have a custom intake manifold made. You could use the existing factory intake manifold flange with at least 2-3 inches of all 4 of the port tubes still connected. Then cut more tubes from another factory intake manifold to weld onto the other 4 tubes already on the flange. Or you could use any other tube as long as it's around the same size and same material. Then you could use a fire extinguisher to weld onto those tubes then use the factory intake manifold neck and weld that onto the fire extinguisher end where the throttle body would go. After all that you then just make vacuum ports and other ports needed for any other hoses that connected to the factory intake manifold.

Here are threads where it has actually been done. I included all 3 so you can get more pictures and a better understanding of how he did it.

Just send me your cracked one. I will weld you up something that will outflow the stock one & probably never crack. Wouldn't break the bank either. PM me if you're interested.

Not much to repair there.

New intake. Almost looks stock but it seems much heavier duty. Hopefully it'll do the job..

Referring to your old manifold: It's a pretty easy fix when you have the right tools. I could make a new flange for the TB on the mill then weld it in place.

However, I wasn't talking about repairing it. I want to cut the stock flange & injector ports off of it, then weld on new runners & a custom plenum. It would resemble most of the aftermarket evo intake manifolds, but cost far far far less.

10 minutes with a wire brush and 5 with a welder would solve that problem.

They'll keep breaking. You can weld it again, and it will break again. If it doesn't crack at the tb housing, it will crack one of the runners... They're garbage. DOHC swap and evo manifold... done deal

[Silvertune]

Why if it's unnecessary? That's way more work and money than fixing a manifold ten times.

If you know it's going to brake then take half an hour with the wire brush and half an hour with the welder and hit each seam then put it in with the factory brackets.

You're lucky that hundred shot of NOS didn't blow the welds on the intake

oh wait nevermind jk

im curious how much torque you have to break that. I would weld it and check your mounts

Yep. I cracked my intake manifold neck early last year. I took it off, bent the large cracked portion slightly open and prepped it by sanding that area where it will be welded. Took it to Muffler King and told them to weld it. It would have cost $20 but the guys like me so they didn't charge me. It's a cheap and easy fix that will last a good long time.
