like the title states, I am looking to buy an AEBS IM for GSR only not Type R or B16!

 

anyone?

 

anyone out there?

 

Don't forget to drill the flange holes out to align the ports when you find one. One of the few that are engineered half decent.

 

I have been told that is only needed if using larger than stock injectors, if that is what you are referring to!

 

You are correct, but that's not what I was referring to.

Port alignment is out on every one I've seen. Oversize the holes to 3/8" and then you can position it to achieve an equal anti reversion step over the entire circumference of the port.

Yes! first post is mine
thanks d00d

 

i'm installing one right now. I've not noticed any port misalignments, but its hard to tell forsure with the knockoff hondata gasket i have (bolt holes are too big). The throttlebody port alignment is bang on tho.

the annoying things are, the extra vacuum nips in a stupid place to have to block off. the extra coolant nip to block off. The supplied throttle body cable bracket requires the cable adjustment to be completely maxed out to take up the slack. And the the fuel rail needs 3/8 spacers to bolt onto the manifold.

Its nice that they are the only ones to legitimally design a manifold with runners designed for the unique gsr head, but please...

 

Remove the gasket, bolt the IM in place, look down at the ports with a mirror. See a uniform anti-reversion step?

 

that sounds like an interesting procedure, can you get a satifactory look at every port match?. Ideally i would have used a stock gasket that actually fits around the bolt holes snugly and then and port match using that reference. I have my doubts about these extra thick thermal gaskets, when not lining up perfectly and creating eddies anyway.

 

I see that we think on the same wavelength . The same reason I quit using them a while back. I feel the tradeoff of heat for flow quality is worth it.

The AEBS is within .5 degrees of the port entry on the gsr. Drill the flange holes out to 3/8" and you can compensate for the error. There should be about .1/16" of step concentric to the center of the port, a very desirable characteristic.

I imagine there may be different runs of the IM, but the two I bought had the identical problem

Oh, and you'll need a long, flex neck flashlight.

 

well i already got the telescoping mirror..

btw, what did you use for a spacer to bolt down the fuel rail. looks like it needs to be a bit over 3/8" thick, and 3/4" round. i don't want to have to go and stack washers or use some nuts to bridge the gap..

 

I used stock oem honda spacers and a washer .035" I think it was, but I have RC's (don't forget to drill the injector ports if using RC's)

 

here's number 4 port with gravity taking up the slack in the bolt holes



pulling the mani up still leaves perhaps a 1/32" ledge, and its slightly to one side. this next pic shows where the bolt holes need to go



i couldn't do this with the thermal gasket because it needs almost as much adjustment as this mani does to match the head ports
