i was looking @ revhard .com and i found 3 CAST bseries mani''s! whats the difference between these 3? revhard told me that only if i had no a\c and a t4 i would be best of with the third otherwise i'd better take the first. i dont get it. the text says that the third one is also available in t3! and the 2nd one performs better than the first one! and if i look @ the pictures, i would say that the 2nd is best of three. maybe they are mixed up or something??? anybody god some info on this?
thanks!

the first one is the standard revhard mani, the 2nd one is a direct replacement for the drag manifold. the 3rd is the non-ac version of the 1st one

if you're looking into manifolds like that, get a blox

Rev-Hard creates two different manifolds that are A/C compatible and one type that is not..


This first one here RHC-18BAC

Is one of their first compatible A/C manifolds that are used. Notice how the flange opening on the manifold is "crooked" to supposedly allow the turbo to set itself slightly away from the block to eliminate the need to shave the webbing on the block (I'm Assuming you're using a T04E Compressor cover). You'll know the difference because the placement of the wastegate flange on the manifold is set right btween runners 1 & 2. This could cause a problem in which you would need to create an elbow to the flange in order to change the direction of the wastegate. This is only necessary on DC2 Integras (USDM) that are utilizing an electronic boost controller due to the fact that the "nipple" in which the hose for the EBC would fit may possibly not allow clearance of the hood.

Now this second one, RHC-18BDR is their second manifold that is A/C compatible, and is considered to be the DRAG replacement. Same design, but because they moved the flange 2mm to the left of the 1st runner, it doesn't cause any boost creep like the DRAG unit. This one has the wastegate so that DC2s can close the hood w/o the need of an elbow to relocate. It gives a little more clearance on the hot side, but because the flange outlet itself is parallel w/ the rest of the manifold, and you're using a T04E on a B-series motor facing the passenger side, you may have to not only shave the webbing on the block, but also purchase an additonal Head flange and longer bolts to "push" the manifold further out from the block.

To eliminate this, especially if you're in the market for a new turbo, You could get the turbo that you want and possibly house it in a T04B housing, which is slightly smaller, but you can still use the same size compressor and turbine wheel combinations as you had before.

The 3rd one is the log manifold w/o any A/C ..RHC-18BT4
does not allow for A/C at all, and in many cases, in order to eliminate the need for additional pipes and dumptubes for the wastegate placement, allows the compressor to be facing the driver's side. (Many people consider this backwards, but in actuality it allows for a more direct angle for the downpipe, and can allow for the wastegate tube to be merged with the downpipe itself.)this is used for those that don't plan on keep A/C (naturally)and is efficient to over 650hp for efficiency and flow. Most of these are T3 Flanged, but have options for T4 flange as you can see the 2 sets of bolting holes in the pic.

Hope that helps.

can be fixed easily with an elbow. revhards will crack..bloxs dont.

Interesting if not an inaccurate response..

I ran a Revhard cast manny for about 2 years with no problems at all. I now run a tubular manifold, but I just wanted to let people know that RevHard makes good quality units from my experience.

DefiantGSR

my cast revhard got a hairline crack.

markvqwerty

ok thanks everybody!
the first one looks pretty crappy to me because it aint got no collector.
the second one: well i dont want to shave my block!
The third one looks nice cause i aint got no a\c, the only problem is that somebody from revhard told me that the 3rd is only available in t4! and i want a t3to4E.
Thanks!

I've ran my rev hard for 4 years now. No problem.

so annybody got a non a/c log style revhatd mani with a t3 flange? or dont they exist?

PM-Performance

i went thru this with you on SHO already . Look at #3. its drilled for a t3 and t4. you can use either. I read thru and didnt even see where it said it was a t4 only manifold.

markvqwerty

im sorry itr 206 but i aked revhard what mani i should use and they told me that the 3rd type was t4 only and if i wanted t3 i schould get the first one! thats way i asked it @ 2 places. if annybody answered with: yeah ive got the 3rd type with a t3 flange than i would be satisfied
thanks!

Let me know. I can help request that they use a T3 Flange for the manifold you need. I've been able to this multiple times

markvqwerty

itr 206 told me on sh that its t3t4 flanged @ the same time.
and you mr shodan do you work for revhard?
i asked wsl if they had it but they thought that revhard didnt make any non a/c log styled manis but they had to check.
thanks

another question for shodan:
you told me that the first type was ''crooked'' to fit a t3to4E and the second isnt but why is the second on these pictures more ''crooked''?or are the pics mixed up? and the 3rd? do i have to shave my block with the third type?
Thanks a lot!

Sorry for late response.

On the 3rd type, the block does NOT have to be shaved because the compressor side will be on the driver side, not passenger, and A/C is not compatable.

As for the pictures, no, they are not mixed up, but are mainly setup for 5 bolt turbos (meaning their exhaust housings)..

thanks!
i think ill go with the third
