I'm building a turbo Zetec Cougar and was wondering if anyone over here is using the OBX turbo mani? If so, any fitment issues? Pretty sure the turbo mani and turbo will not clear the radiator fans on the Cougar, and I'm wondering how much extra room the Focus has (if it has extra room) also if any of those problems exist.


The manifold in question.

I heard after a while the welds actually start to crack. This was on the honda forums, so idk if its a dif design...but looks the same.

yea, knowing my luck they probably will. I ran the obx header while N/A it never cracked, so I figured I'd trust this one. I wonder if they just hung the turbo from the mani though.. that'd probably crack it a little faster.

Obx = junk

ANyways ppl should probably offer suggestions to the question, not on his manifold choice. Unfortunately i cant help.

use that manifold, the welds on it look great, about as good as any other stainless header i have seen, if your worried about all that weight hanging from it make some support brackets to bolt to the turbo to support the weight, alot of guys run supports because turbos aren't the lightest bolt on parts--- be sure to post pictures of how it turns out and good luck.

Its not the look of the weld its the penetration and what rod and material they use. The manifold will crack. its made out of crappy china metal that has way to much carbon in the metal. it makes the stainless weak and it actually rusts its horrible ss. but they have the concept down.

Im not trying to trash you mani im just telling you how its made and with what

I agree with you, it needs thickness piping bigger and it needs to be done with less carbon in it...

so i say this, as for the welds yes they look good, as for penetration its pretty hard to look inside the tubing, send me your manifold and ill have it x-rayed by NDT Corp. and see if the slant eyed bastards can weld as well as it looks. As for the material used to make it, yes it is china and they are known for their crap metal, for gods sakes the manifold is probably made from the beer cans our dads drank in the 70's---- but how do you know that the materials that everyone is using isn't from the same pot those chinese "knockoffs are made of?

Because obx is known for there chinese shit metal. and that manifold is not even back purged meaning the inside weld is contaminated and isnt strong

SPA is probly the best out there.[thumb] That or maybe one from top speed performance if ur looking a tubular mani. Don't think it'll work in a cougar though.

I would also look into the SPA manifold , the topspeed is to bulky and a waste of space for what it offers , the SPA is a cast manifold , small and works very well

I have the OBX manifold. If it breaks it breaks. Onto the question....

Fitment issues?

I remember a guy tried installing one...it will be a very close fit with fans on a Focus. I know that the Xios kit comes with a manifold like that and it uses slim fans. Also, the guy had to grind off a small part of his block to fit the OBX.

ok. Already looking at slim fans on the flip side of radiator, but apparently it will fit the focus sooooo hopefully I cn squeeze enough room out of the cougar to fit it. Thanks!

Yeah, if you don't want A/C and can install the fans as pushers, you should have plenty of room. Since the OBX mani is thinner than a slightly higher quality unit, I would definitely look into support brackets.

Already made some support brackets, and removed the AC also. Lots of room.. thinking about a highly unlikely radiator relocation.

support brackets *upside down engine for a better view of brackets

^^ I like what you're doing......

but I'm gonna be an ass [hihi]

why not the the 2.5 or 3.0L swap? [hihi]

[joke]

ha, new subframe, ecu, trans, etc. Just playing the hand I got dealt! It's different and fun to have to work out bugs that haven't been looked at much.. especially fun since it's my first project car.

edit: who knows though, I might get a v6 project down the road ha.

Support bracket wont help except for the weight. the problem is the shit metal its got to much carbon in it you can sopport the whole thing to hell. it will still crack because of the carbon. just stop now and get one made out of sch10 weld els and a real merge collector

man, I understand I'm a cougar on the focus forum, but really if the mani cracks it cracks.. it's already bought and done with. I'll worry about that problem when it happens. Just trying to get the thing in the car right now.

not to be a jerk, just saying. Thanks for the concern though..

i think it is cool, what kind of power you looking to make? sucks that you wont be able to run the stock fans. they flow a lot better than any after market ones. good luck with the mani, if it cracks just weld it up, lol

true true! if it can be done in a fo, it can be done in a coug.

AH I still regret NOT getting the V6 cougar I was looking at. oh well lol.

eh, my goal is about 300hp. Should be plenty to be fun hahaha.

nice goal [:)]

LOL at cougar on focus board, because I'm a focus on the cougar board.

what turbo you using? is your engine built?

JE 9:1 pistons, eagle rods, ARP main/head studs, light head porting, comp stage 3 cams.... might end up changing them out depends on how it runs.

Still up in the air on the turbo. Local shop recomended a Garrett 60-1 .63... I'm a noob with turbo's really..

Turbo in pic was a 2 year old "project turbo" rofl. It's no name and may actually get some use if I can't save up enough to get a real one in time.

cool, ive been curious how a 60-1 would do on a focus. you should go a head and push about 25psi and see what it will do. you have plenty of motor.

There has been many 60-1 its about the same as a T3 S60 STG1 and many have run the STG3 with my old kit , even did about 6 ZX2 with the T3 60-3

Tom

super 60 same as this one? this one is larger than my 50trim and is rated at 550hp

damn I like the ported shroud one just cause it looks so damn cool [thumb]

I am running the T# s60 STG 3 w/ Dual BB

plenty possible they are ton of 300hp+ zetecs out there

the turbonetics super 60 that Josh ran on his zx2 did pretty shitty. At like 12psi it was barely hitting 200whp. He was also running svt internals. Pretty crappy for a 1400.00 turbo.

Odd , Dont know who josh is but I have done many t3 s60 and made 200 at 10psi and 240 at 12 , maybe he had other issues or tuning issues , the Turbonetics T3 S60 STGIII works great on the Zetec engines

I personally think it was a list of things. The turbo was remote mount above the tranny, some of the IC piping seemed rigged. And the tuning was done local, and they had only touched one other zx2 with sct.

Hah yeah, then in that case it wasn't a function of the turbo at all.
