Adapting Greddy manifold to KA?

[nightwalker]

I was wondering if anyone has thought of this? Or if it has been looked into extensively? Do they share enough to be able to adapt it? I was thinking about this as an alternative to extrude honing my KA manifold. Thoughts?

You mean the Greddy SR manifold. If so, there's no way, the spacing is TOTALLY different. If I were you I'd look into getting a short-runner custom manifold made, many shops can do it for less than what it would cost to buy the Greddy manifold period. If you do that you can clean up a lot of space by getting rid of the dual arc-system the KA uses stock.......

[aleph1]

Id like to know why the dual arc system is used. Like what are the benefits? I know the long runners improve torque, any other reason?

[trpower7]

You pretty much nailed it. Long runners increase torque, how do you fit long runners in that kind of space, you arc them.

[aleph1]

Interesting...=)

wrong. the spacing is close...VERY close to the DE spacing.

close enough that i'm seriously considering checking into this now that i've got my convertible .

/threadjackYou got the Vert' demetrius? that's great to hear!/threadjack

[TrunkMonkey]

yup. i got her today !

r u going with BOOST??

[TrunkMonkey]

yup. gotta get the suspension stuff outta the way first.

I assume we are talking about the intake manifold. If so, yes, the SR manifold is almost a perfect match. According to Sm at Jspec, the runners lined up. The bolt holes did not. Not sure how easy it would be to make it fit though.

And long runners increase low/midrange torque. Short runners provide better high end torque.

[trpower7]

I stand corrected.......still don't think it'll work though

I remember people debating this a few months ago, but no one ever followed through on finding out if it worked. Maybe someone should now:D

[Projex240]

hmmmm...all you would need is to cut the flanges from the KA manifold and adapt them to the sr manifold...if it were only a perfect world....sigh....

no really...it sounds like it may not be all that difficult. Problem is finding someone with enough balls to hack up an sr greddy manifold to make it work.

No fun at all...............What about just opening up the mounting holes? Are they that far off?

give me a few months .

No, you do it now!:D

[MainEvent212]

someone find a used/junked greddy manifold...hah it sounded smarter before i said it out loud...

[j-z]

why dont you just get a sr and a ka mani gasket to compare? that way you can see how far off the ports are and if theyre bout the same you can port and redrill.

92 H22 prelude with 4ws? damn they only made a handful of them. hows the 4ws work for you?(totally off topic)

[j-z]

first they never made a 4ws prelude with a h22 theyre all h23. and 4ws is only good for parking lots and such. its worthless at higher speeds and i dont like it. thats why i took the fuse out. back end has slid out on me way too many times and i didnt really like that too much. with the fuse out now it just hugs the road, its nice. but time for rwd traction sucks. hopefully she will be gone by friday and i can get my hands on a 95 se asap.

[andrave]

oh I thought they made them for a single year with H22 and 4ws, I thought I read that in a magazine.must be like the only FWD car with RWS.anyway yeah FWD is... blah. prelude is a nice FWD though, dont mean to diss.anyway sorry for the disruption to the thread.

[TrunkMonkey]

a cheaper alternative to greddy.

-demetrius

[Structure240sx]

much cheaper. is that what ur goin to use to adapt to the ka?

[TrunkMonkey]

it is now...unless something even cheaper comes along in the next couple of months .

get a 1/2" thick piece of sheet steeldrill and countersink holes for bolt heads (for KA bolt pattern)drill and tap holes for bolts on the SR intake pattern

cut out the ports and shape them to match.

seriously, there is practically NO difference between the KA and SR exhaust manifold spacing. Logically, it would follow that since the two engines are so similarly designed, the intake ports are spaced roughly equally.
