Hello.. Well I believe my S4 either has a failing gasket, or cracked exhaust manifold so I'll be tearing into it shortly. I'm thinking I may as well upgrade while it is apart and noticed some cheap tubular exhaust manifolds on ebay... I searched ebay manifolds and found nothing, so I'm curious if anyone has tried these out, or if they're cheap junk... The only thing I could find on ebay was a used HKS unit but it was around $500.... I'm just thinking if my manifold is cracked I may as well upgrade now..... I know I will have to go externally gated etc.... if I go that route... If I could find a deal on a nice S5 mani and turbo, I'd just upgrade to that setup for now. Just want to get rid of the nastty exhaust leak/rattle.
Here is the ebay unit:http://www.ebay.com/itm/86-91-MAZDA-...sories&vxp=mtr


Thanks...

 

no. dont get that ****.

also, the s4 and s5 turbo have a proprietary bolt pattern that no company makes manifolds for.

actually, i think one company does, but its australian and i dont have the link any more.

 

Ok, for that much $ I figured it is probly junk that I'd have to modify to work. I've never had anything cheap ebay actually fit....

Guess I'll plan on going S5 mani/turbo.

Thanks

 

Just picked up a S5 Turbo,mani, lines, sheilds, from a user here.. Now I hope the old one comes off without breaking stuff....

 

Maybe you should stop buying cheap ebay junk. Save your pennies and get some parts that you will actually appreciate.

 

I haven't tried any ebay junk for a long time! Thank you very much! Just spent
$5k on my '99 Eclipse GSX with Parts from Forced Performance and ETS..... PERFECT FIT.
I only mentioned ebay stuff because parts like manifolds are prettly slim for FC's.
If Forced Performance made a manifold for the FC's I'd be all over it!

 

make sure to get the mazda metal turbo and manifold gaskets! the other stuff does not work, believe me had to pull the turbo off 3 times. i can do it in less than 2 hours now

 

Ok. I was going to try to re-use the exhaust gaskets coming with the S5 unit if theyre in good shape. I'll probly end up buying new ones though.

Anything else I should know about pulling the turbo? I've done several DSM's (easy), and my 944 turbo twice (NOT easy)...<-have to pull plenum, move steering rack, etc....

Looks like the bolts may be a mother to get at on the FC...?

Thanks...

 

S5 Turbp, manifold, lines and shields match right up to S4?

 

nah pulling the turbo is just time consuming. it comes out through the bottom. take care when undoing the oil feed and return lines. other than that its easy.

 

Probably not once you hear the price of those little bitches..

i would buy from these guys.

 

Oil feed lines are a little different. Just swap the S4 ones over to your new S5. The manifold heat shield is also little different from the S5 and doesn't match up. It can be made to fit, but it won't be pretty.

 

Sweet! Its coming with the sheilds and all, so I should be good to go... I'm going to try and re-use the exhaust gaskets, but nice to know I'll be using the S4 oil, coolant lines. I wasn't what to do there before. Thanks!

 

Exactly! I normally just replace gaskets regardless, but the Mazda ones are hella expensive..... I'm hoping I can re-use the exhaust gaskets. The turbo is supposedly off a low mileage car, so fingers crossed...
Thanks.

 

Whoah! They have a nice selection of Manifolds... I wish I would have known of that before going used S5 stuff.... Oh well I kinda like to see what I can get out of stock parts before I ugrade anyway....

Thanks.

 

are they actually good manifolds?

 

I would also like to know if these manifolds from the AU are good. I'm surprised racing beat doesn't make one..

 

I was thinking the same thing.....

 

Looking at their S5 turbo manifold, the turbo mating flange is angled relative to the engine mating flange. This would either cause interference with the intake/block or space the turbo outward requiring a custom downpipe. And you'd have to re-do the A/C and heater lines, if you're into that kind of thing. Looks like the S4 one would do it too, but the picture isn't as good. Either way, it would be a lot of work just to run a stock 20 year old turbo.

Fabrication and materials look alright, but the design is definitely not drop-in.
