I was looking at getting an aftermarket exhaust mani, but i did not know witch one, i was looking at exoticspeed w/ a top mount for turbo. I wanted to see what people were running for exhaust mani and if they had any trouble fitting it in. Oh ya i have an s14 w/ rb25

Looks like a rebadged Wasabi Garage manifold. Pretty equivalent to SSAC. What are your power goals because one can go a loong way on the stock manifold?

Wow i like that rebadged wasabi garage mani. Good crative points. I was looking to put out around 500hp. Would you suggest just getting a turbo elbow to make it a top mount, they make them don't they.

I don't know how well the turbo fits on those, because some don't move it out from the valve cover much. Buy it and see if it fits. Then you will need a new turbo elbow with O2 bung etc. to make it work.

Either that or spend some money and get a decent manifold. Hell, 6boost steam pipe manifolds are only like $900 shipped and they will perform arguably as well as the full-race and lovefab manifolds for the power range you seek.

Im building a kit around a ebay manifold and will let you know status of it. I dont care I bought the manifold off a guy on here for $100 and see what happens. I had all the other parts around so Ill build the d/p and intercooler pipe to see what happens. When I get to the dyno Ill post results and see how it lasts

i bought that apexi top mount manifold from the guy in australia on here, and he had it on his car running pushing a considerable amount of power, and when i get it and try to bolt it to my motor, it wont go on the studs. Any one have any input on this, i have drilled it out a lil bi to make the holes bigger but should i cut the studs a tad bit shorter? i mean it came right off his engine and is going on mine.. Nothing is damaged on it, it is perfect. just wondering if anyone else has had any problems fitting used manifolds onto the studs? Oh btw took the Stock IM off last night, and guys i have not ran into one dirty part of my engine yet... Valve covers not a drop of nothing, cams, clean as crap, im bout to take the head off and am hoping for the best.

i recentley upgraded to a t-61 and a topmount mani and had some prob with my studs all i did was remove them and used some bolts instead.napa sells the right bolts for your engine.
