turbo manifold???

the way you generally tell if a manifold clears is if the turbo port is close to the second exhaust port. Its gotta be at least half-way in the middle to have any chance of /ac, that's what i noticed from my manifold. Even then it's a tight squeeze

Exacery. Turbo exhaust housing (when compressor housing on drivers side) needs to be at least smack bang in the middle of 2 & 3 cylinder runners to give enough room for a down pipe to clear AC compressor.

Also you can also tell if its AC friendly if the turbo flange is on an angle to clear larger frame turbos away from the engine block webbing and bell of the gearbox.

Heres some pic's cause I am bored:

Ac friendly manifold:

Close proximity for downpipe (3 inch). Ac compressor on right (passenger side). (photo taken from under car)

fark thats close nice manifold but and u can fit a 3inch dump to.... thats where mine fails mine can only fit a 2inch i think... though my turbo exhaust wheel is only 2inch but i think it should still b 3

My ram horn performed much better than my current Rev mani. It must have dropped .02 of a second on initial spool but it spooled up quicker and felt it held more power on the higher RPM. I wouldnt mind looking at a top mounted Ram horn style mani where the ram goes under not over and your turbo sits nicely along side your motor and is directly in front of you when you open the hood. Seems alot cleaner install.

Like this setup below, but a really nicely made one something that's not gonna break on me and has alot of support for the turbo so it doesn't crack over time.

I wonder how much a nice one would cost. I could sell my steam pipe one for a bit and get myself one of those.

Top mount manifolds for B series:

Full Race $1199 usd
Peakboost $899 usd
AFI $1050 usd
Love Fab $1099 usd
Spoolin Performance $900 usd

None of the top makers put extra bracing on thier manifolds to support the weight. Just remember that a 'hollow pipe' is very strong. So taking that, if the material is thick enough and the welder knows what hes doing there will be no problems. Majority of those above provide full backup on thier manifolds too.

i know Full Race manifolds come with a Lifetime warranty

**Riced_Civic** · 04-01-2009 02:41 PM

yes, i sooooo want a top mount now

**A-man** · 04-01-2009 02:54 PM

yeh plus they r made of steam pipe that helps sooo much those china manifold like mine arent.. it depends on the steel used weather it cracks or not

if u gonna sell ur manifold fast fwd let me kno im very interested

**DLO01** · 04-01-2009 02:59 PM

The ones I listed above are all Stainless Steel.

**A-man** · 04-01-2009 06:40 PM

yeh but there is different grades of stainless steel on the cheap manifolds they use the cheap stainless grade thats y they crack there not designed for exhaust manifolds where things like steam pipe that comes in stainless is designed for these applications

Yeh my current is steam pipe, Very Very strong and ive had no problems yet. A-man give me a month or so to think this threw cos im thinkin about getting a new turbo.. Dropping my gt28rs and getting a gt30 or gt35/40 with high mount and tune it to 22psi or something...ill think it through.
