I am looking for a turbo manifold that will be able to support 600-700hp but also allow me to retain power steering and air conditioning. I have searched and cannot find any solid answers.

My build includes
B16 head with skunk 2 valve spring and retainers and Gsr cams (looking for a better cam)
B18b1 block
B18b1 crank
Darton mid sleeves
Block girdle
11:1 cp pistons
Victor x manifold
Id2000 injector
Walbro 450 fuel pump

Sending everything to darton east engine building in md to have the short block blueprint balanced and assembled


But right now I need to find a turbo manifold that will allow ps and Ac and be good for 550-650 hp.

Any help would be appreciated guys.

 

The only manifold I can think of would be a Ramhorn manifold. There is dude that has I think over 700+ and he has AC and power steering. I've seen his video on YouTube and here

 

Yes. Kooks "Ramhorn" manifolds., or quick 4a/c "mini-rams". They are usable with a/c and power steering provided the right equipment is purchased . You have a variety of companies to choose from including go-Autowerks, spoolin' performance , AFI Turbo, BRMS Motorsport, etc.

That's as definite an answer as you're going to get

 

I have AC and PS with FullRace ramhorn I'm sitting at 470 and I think 500-550 would be doable on my setup. I think a little larger turbo would get you where you want to go. I'm also sitting at 9.25:1 instead of 11:1.

I do plan on going back once I get the car back together to go for 500whp. Turbo has more psi in it so I think it will be easy to do.

 

I've seen a few 600+whp here with BRMS and DOC Race.

 

Thanks guys... I am now looking toward a ramhorn style manifold. Any you guys reccomend?

 

most companies are reputable as far as material quality, weld quality, and warranty so it's really up to you and what your budget will allow but obviously stay away from anything "ebay" or chinese in origin. Granted I don't think they've copied an a/c compatible manifold.... yet

 

We've already mentioned the companies names.. Please google them to find their appropriate sites.

 

now one last quesiton, what turbo with a ramhorn manifold that will allow for ac and ps cant i use. basically what size/ kind of turbo would you guys reccomend to use for my power goal of 600-700 hp?

 

dude just do your own research without asking these questions. just look for a t3 flanged turbo and go from there

 

im looking for brand and size. t3 or t4? just trying to get info man

 

Having built many turbo B series Hondas with ac and without and even doing ac, ps with full size radiator. Your ac will never work like a stock Honda , there is to much heat soak under the hood, flow through the condenser is poor also with large front mount intercoolers. Plus having ac compatible manifold the turbo flange gets rotated and working on anything is a pain in the ***! recommend getting v band flange for downpipe makes it a little easier

 

Never heard of this before. I could care less about P/S in a Honda but A/C is a definite must!

 

Yea the intercooler will eventually heatsoak the condenser, not to mention high under-hood temps heatsoaking the pump and lines to the heat exchanger... so you won't really get ice cold air, more like warm beer kind of air lol.

Although there are steps you can take...

High CFM electric slim fan to replace the OEM, you can wrap the ac lines and all exposed components (like the dryer, anything else you can think of ac related to wrap) in heat reflective material, also wrap the compressor in the heat reflective gold foil (or pull it apart and ceramic coat it, that's going all out for cold air though lol) in addition, you could build a shroud to fit around the compressor to block radiant heat from reaching it. I would wrap the shroud in the gold foil as well... while still keeping the compressor wrapped.

You could also install some thick nylon washers on the bolts between the compressor and it's mount, this would eliminate a lot of heat soak as a direct result of the compressor being bolted to the motor. They would basically act like phenolic gaskets you use between the head and intake mani and intake mani and tb..

Also, a turbo to support those power goals would have to have a T04S or larger compressor cover, which if I remember right, won't work on the AC manifolds as it hits the block and theres no way to clearance it. As some AC manifolds turn the compressor housing towards the motor... The largest housing you can run (again, IIRC) is a T04E or a GT30R Ported shroud style cover.

some ramhorn manifolds, like the Full-Race offering, turn the compressor housing out towards the radiator, the downpipe is the key piece in making it AC compatible, takes a very tight cheater bend to clear the back of the compressor. With their style of manifold you can run the larger T04S housing, which is basically a requirement for your desired power levels

Here is their b series ac kit page, so you can see what the manifold looks like... then you can look at other companies and see if their ac compatible ramhorns are of a similar design, you would still need to follow the modifications listed below

The two links above are the full-race ac kit install instructions and the modifications to the AC mounting bracket you have to do if running the full-race stye manifold, also you have to run a half size radiator (no full cores) and you have to trim half of the PS bracket off, the left side, so then only the right bolt would be holding the bracket in place

so you need to decide... 700hp and no AC, or a lower power goal and keep your AC

 

^^^Thanks for such a lengthy description of my interest in keeping A/C. Maybe I should've mentioned I'm never going to look for more than 350 WHP at extremes. IMO that's a bit ludicrous on any boosted car driven on the street. NOw, back on topic.

 

Then you don't need a ramhorn manifold, either. You can easily use a tubular log and keep all the accessories and amenities.

 

so you said 600-700hp in the first sentence and then you say you're looking for a turbo to support 550-650hp.... and now you're saying 350.... that makes no sense.\

None of those sized turbos would be any good at 350hp, you'd have lots of surge issues.

make up your mind because at 350hp you could use a typical standard cast manifold, retain ps and ac with no modifications, and still make your power goal without issue

pick your definite power goal then go from there... because with you having two different power goals in one post, then an entirely different (and much lower) power goal in another doesn't help us help you, nor does it help you at all....


make up your mind

 

Probably the biggest manifold I'd ever use would be the Inline Pro stainless cast but, more than likely some log-style shorty manifold would work just fine for me.

Mmmm you referring to me or the OP? I'm definitely not looking for 600-700 lol, 350 is my ball park.

 

I got confused, lol

 

That's cool bro, we all have our brain farts from time to time.

 

Me more than often it seems lately... that of course could be my lack of sleep constantly, the amount of pain im in, pain meds, brain damage from the car accident, stress, and the days I'm just an ******* with no patience lol

 

Wow man! Sorry to hear of your situation but I'm glad you made through this far. Obviously someone has been looking out for you and you're still here for a reason. What little pain meds I've had in my life I despise! I have a low tolerance to begin with so I have to be careful what I take.

 

Keith Richards would envy me right now lol

 

OMG LOL!

 

here ya go man. 650whp, a/c, heat, and could have power steering if I wanted but deleted for simple fact of a manual rack and cleaner engine bay.. kinda miss it though

about the only thing i've had to update since is my catch can to a T1 setup, and had to up it to a walbro 400lph pump just before the dyno. Also needed ID1300's to make the numbers. Hope this helps man
