Evo3 vs FP manifold

[94'TSI'AWD]

I got an MHI evo3 Big 16G turbo for $275 the other day and now i need a new manifold. What would be better A Forced Performance Manifold or an Evo 3 Manifold. I am buying it from a friend and there is only a $50 difference between the two but for power output and flow and spool time which would be better? Obviously the FP has a bigger collector and runners but I dont know much about them. But the Evo3 Is rated the best factory exhaust manifold, i'm only planning for 300 -350 Hp would the stock evo 3 mani be good for that or should i get the FP? Please help

The Forced Performance race exhaust manifold is on sale again guys. I am so glad that I waited it out.

 

[GsXdSmKingGsX]

FP makes a great manifold that I would swear by.

 

[92AWDHX40]

Yep i want the fp as well, looking to get some things ceramic coated, thats a nice piece.

love looking back at these old threads. . .Pboglio, I love your endevour. And calling BS on your results for your tests is silly.

But, I WILL call BS on the reason not to use a real cold air intake. Hydrolock is like crankwalk . As much water as I've injected in my motor? geez, At lower ve in the rain when I'm scared to run it around, well guess what, it has lower ve and total intake combined. At WOT, I am injecting hundreds of cc/min. . . No rain mist can duplicate that. And further no mist of significant volume can come into the charge pipe mouth with a normal typical CAI setup.

There's no excuse to be too lazy to install a CAI. Because you've proven that a CAI will net incredible gains. Your intake ending in the engine bay even net such high gains when taking some of the heat away with a heat shield that you posted your results. Your results are excellent. An intake pipe 'outside the box' is stupid easy to make and will net better results than leaving the entrance in the bay even with a shield/coating/etc. on the manifold.

I love the fervor, but the thought proccess is a bit flawed .

Stock 2g manifold will do just as good, you might get it ported for better results.
IMO i would spend the money somewhere else.

 

[jof_03]

can you do the porting yourself without the machine?

By "machine" I assume you mean something like a die grinder? I guess you don't need it, but using a hammer and chisel would take quite a while.

In my opinion I would get whatever one is cheaper. Porting a evo3 manifold yelds just about good as fp manifold, I would only buy fp manifold when on sale for $175. Your talking about such small air flow gains against eatch other it's rather pointless unless u need 110% out of your setup. I do know the fp manifold works great with clearance like with an hx35 and does look nicer, but if you run heat shield or like stock look evo 3 is for you.

 

[ronnievermilion]

I'm running a FP and They don't need to be ported. Plus they look way better.

I had mine coated with TBC. Mine does not seen to get very hot with the coating.

I think FP is the best manifold you can get before stepping up into a nice $1000 tubular manifold.

 

[vicore]

Will the stock heat shield fit on the Evo3 manifold?

Is anybody using the lower heat shield? Lower stock shield fits the Evo3 turbo?

Those pics are the first i've seen of a true mhi evo3 turbine housing. I cannot believe how much larger and more tapered the ebay turbine housings are. Also the wg port on the ebay housing looks far surperior, both larger and better shaped out of the box. The rest of an ebay 16g may be garbage but I'm willing to bet the turbine housing (with a proper and knowledgeable port job) will make more power and flow significantly better than an mhi housing.

Anyone seen any of the gt concepts manifolds recently? I would like to ditch my tube junk and would like to try that manifold mated with my ebay turbine housing and see ehat some cheap parts are capable of.

 

[Doubleot]

Fp hands down

 

[TheGameTG]

I have a ported Evo3 and I like it. The FP manifold is one of the best though for price to value. For $50 difference, it's probably worth it to go with the FP manifold. That's only my opinion though.

Word go with the FP

The GT Concepts manifold sadly is no longer made because of the overwhelming number of sheep like Doubleot above me who just say "go FP" with no kind of data and proof to back any of his OPINIONS up.


The eBay/GT concepts turbine housings are far superior to the Evo 3 turbine housings. They are made of the same material as Donniekak said, and are the basis of what FP's new "8cm" housings are. Also to everyone saying you don't need to port an FP manifold......the FP manifold needs to have the runners smoothed and the casting "roughness" also smoothed out. You don't /need/ to port an evo 3 exhaust manifold either technically. But it helps.



From personal experience, the GT concepts exhaust manifold > the FP race manifold. Off boost throttle response increased, spool up time decreased, low to mid-range was a drastic increase, with no difference in upper RPM's between the two. I briefly debated going with the FP race manifold, but in the end the GT concepts offers too much of the stuff I'm going for in a street car. Add to the fact that I can use a legitimate heat shield, and not pricey coatings or wraps that damage the manifold/increase the risk of cracking.

This is exactly why i try things for myself. I like winning races for half the cost of the next guy. Summer 2014 im planning to push my 7 bolt 16g setup as far as it will go and a "stock" appearing manifold is in the plans. My tube manifold is more "bling" than i care to have under hood (although its been on over 2 years and ran hard over 20,000 miles with 0 cracks...and its obx) and i need to drop under hood temps badly. I spent probably 10+ hours on this manifold porting entries and rewelding flanges, spool and top end are drastically improved over a stock 2g mani. I don't care to go backward in performance or spend that much time porting another just so im satisfied. Guess its time to hunt for a used gt concepts mani. Maybe a 14b to stick in my ported ebay turbine housing and see what happens.

I make a heat shield for the FP manifold, there's a link to it in my signature.

This is not my question ^^

I just want to know if the stock upper and lower 1g heat shields fit the evo3 manifold and turbo, cause I've been told that I need the heat shields for our German TÜV
and the evo3 heat shield might be delivered in june

 

[Steve93Talon]

Sorry, I quoted both of you and only replied to the 2nd quote. The 1G and 2G OEM heat shields will fit perfectly on the EVO 1-3 exhaust manifolds.

 

[vicore]

Thanks, so far.

What about the lower heat shield? MD199064
Is there anybody who even tried it

 

[Steve93Talon]

The lower shield should bolt up to the turbine housing fine. The EVO o2 housing is a bit larger than a 1G/2G, but it looks like it has the same threaded areas for the lower shield. I'd use a 1G shield, since the o2 sensor is in the same location. The 2G o2 sensor is down by the outlet so the shield is cut to clear it in a different spot. Worst case, it should be close enough that you can just tweak it and maybe drill a couple new holes to make it work.

Both shields already ordered, thanx a lot!

Bringing this thread back from the dead.

I'm in the market to get an fp or evo 3 manifold, I have a Pacesetter right now and its a piece. It keeps cracking, even with it wrapped my underhood temps are unbearable.

I want to keep the same performance, if not more then the pacesetter, but i am not sure i can justify 175$ more just for the fp manifold. especially if that will just have heat problems too.

Any insight?

I'd like to bring this back as well. I know people say go FP, but most the folks saying that also follow that with a statement about the top end flow gains. What about for a road course/street car? Doesn't the evo have much better low end pull (which a 2.0 desperately needs)? I would like to have a very dependable 350+awhp which means a little larger turbo than normally used for a track car (special sauce TD05H 20G). So if I understand correctly, the Evo3 would allow me to get away with a bigger turbo and keep more low end power and quick spool. Am I getting that right?

 

[ed1380]

If you want to 350hp and for it to spool fast then run a evo3 16g. It flows in the mid 40lb range

I like the EVO3 GT manifold for road race cars.
