Exhaust Manifold - Remove Studs?

Hey all,

I just got a brand new single kit in the mail. I'm trying to put the Exhaust manifold on, and it seems like there is about a zero percent chance of that thing fitting on without taking off the manifold studs that go into the block and then putting them through the manifold to bolt it on. I have tried all kinds of different angles and I think it's impossible. Is there something I'm doing wrong? And if other people have faced this problem, what is the best way to take out the studs?

It's an A-Spec single manifold.

Ok, I was being a baby, the studs were pretty easy to get off.

However I've run into a much bigger issue. I'm rather new to Single's, but there is no way that this is the right manifold, this thing sits WAY too far forward.

Here is a picture, sorry the quality isn't very good, my camera is messing up.

What makes you think that it sits too far forward?? Comparing your pic to the pics on a-specs site, it appears that your turbo is sitting correctly.

I am puzzled as to why you would have to removed the exhaust studs from the housings.....

I guess you're right, but I only have about 2 inches between the front of the turbo and the back of the Radiator inlet, gonna be tricky finding an intake.

And the front of the turbo housing doesn't really fit because it hits the front of the A/C tubes as they go up, but I can bend them out of the way.

I had to take three of the studs out because there just simply wasn't enough room to just slip the manifold right on. A combination of the studs being too long and the flange being so thick. If the motor sad an inch or so to the right, then I would have had enough room to simply slip it on.

Ok, after looking at a few old posts I've determined that I have the long runner manifold. Is there any advantage to the Long runner manifold over the shorty?

a longer exhaust runner will shift the power band up in the rpm range.

Don't bend the a/c lines too much, they like to crack if you go too far

The long runner manifold will give you better response due to more exhaust velocity, and also better overall power. The short runner manifold we offer is meant to acommodate those that want to retain their factory air pump and/or run a v-mount I/C set-up. If at all possible, the long runner is the better choice of the two for power and response.

Let me know if you are having any issues, I will gladly walk you through them

Nah man, that's for the answer though. I think i've got it all down, I would like to thank Crispy and his website, his single install write up has been priceless to me, it has helped me a TON.

I still get my car inspected in DE, and they don't do visual inspections for air pumps there so I just gotta focus on passing emmissions. When I finally switch to Maryland I guess I will have to look into an electric pump.

I guess my only other real question is to what people recommend in terms of an intake filter that sticks out no more than 3 inches.

No more than 3 inches will be tough, but for tight tight areas you can try the HKS SMF filter. It's pretty thin and usually fits in low clearance areas with our kit...
