Picked up a cheap civic shell figured why not put my integra's old engine in it(bolt on gsr). the guy threw in a ultra series street manifold(yes it's legit) would I see any gain to using this over the pro series one that's on there now ?. I have one on my integra's b20v(247/162) so I could just sell this one but wanted to ask first. plus I'm sure there are some other who may want to put this on their gsr's etc. I have a stock b20z2 block lying around that i'll probably turn the gsr into another b20v if that affects the input.

thx

 

Sent it to me I'll test it out
Im not a fan of the S2 pro manifold on GSR heads. The only intake made to match the GSR downward facing cast is the AEBS, that I'm aware of, but I haven't seen a ultra in person. I'd love to run one but I'm not about to fork out the cash on a relatively new part with not alot of dyno time. For $700 it's just not practical for a DD street motor. Hell a $200 AEBS and a $500 nitrous kit is more bang for the buck.

 

Ultra STREET not Ultra RACE

 

this is the ultra street one I have which is 398$ msrp would love the "race" one for my b20v tho. so in short is the "ultra street" too much for a healthy "bolt on" gsr or a b20z2(9:6:1) with gsr head.

 

I just looked them up again and I did in fact click the wrong link and looked at the wrong price. My bad.
I would think it would sacrifice some lows and mids for with stock compression and cams

 

more then with the pro series already ? hmm arguably I could just bolt it on and try but then it's "used". with the stock b20block being able to go to 7K only that may not be the smartest. if anything this will go on the gsr and i'll sell the b20 block

 

If you decide to sell it feel free to PM me with a price. I have an AEBS sitting in my garage I got for $150, but I'd be willing to fork out a little more cash and give it a shot.

 

On 1.6L - 1.8L B series with bolt on components and a mild cam the Pro Series manifold with a 70mm throttle body that matches the inlet work quite well.

On 2.0L+ or anything running Pro cams or equivalent that ultra street manifold with a 74mm throttle body to match the inlet makes better power midrange and up.

On really nasty setups if you take the time to port those thick velocity stacks that manifold flows extremely well.

This is another one of those "match the part to the build" kinda parts.

 

^^^that's what i was thinking i think i'll just sell it and use the extra for thing for the integra. Maybe some head porting lol.
