The guys over at p.p.com 3g's are running DSM turbo manifolds, when i've been searching here there are people saying they're no-where near.
They must be if they can install them and we were stealing their ludespeed manifolds??
any updates....

are you sure they're not talking about 4g's?? WIth the 4th gen accords, the DSM manifold basically bolts right up.

yeah, my buddy is turboing his 3g lude with all DSM parts...

i wonder if the exhaust ports on a b20a5 are close to an a20? Im not worried about the flange...

got a question tho.... if the 3g lude b20a5 will not got into an accord then why do they come with a b20a in japan? Im sure their refering to the one-and-only b20a...wtf

B20a5 exhaust ports are the same as the jdm b20a aren't they. Those ports don't match to the a20 but it might be an option for the b20 guys.

Yes, it's the same as the B20A. (not even close to the A20A)

The b20a and b20a5 exhaust ports are the same but the stud holes are a tad bit off. But not much of a problem. The stud holes can be modifed so i fits perfect.

U mite find it hard to believe this, i've spent all day surfing the net between forums (like ye de) using the searches and using the searches again and again... Thats how i cam accross the picture in the first place and NOW when i need to find it again...well, i havent yet! so sick....all i am reading is people telling other people to use the search...and i'm using the search!!!! how annoying!! I'll find it... u have no idea how determind i am now......and it sucks!!

i've heard the dsm mannys are pretty universal,

I dont doubt, that with some modification, they would fit.

yea if anyone finds info for a dsm manifold let me know, like what years and models and crap they come off of. I would love to get the manifold and make it fit with little modification along with the turbo for my b20a.

Well help me find it in the searches on the p.p.com 3g forum again

Any DSM turbo manifold can be made to fit ours. THe TURBO manifold needs to be out of a first or second gen DSM, ie 90 - 99 eclipse, 90 - 98 talon or 90 - 94 Laser. All these cars have to be turbo obviously.

THe evo1, Evo 2 and Evo 3 turbo manifolds can also be used.

The turbo manifolds from the above cars and years can be used to fit our honda 4th gen and up accords (F22 and F23 motors).

THESE WILL NOT FIT THE A20.

Why wont it fit?
The exhaust ports for the Cylinders 2 and 3 are designed in a way that they resemble the exhaust ports on older V8s. These exhaust ports are closer and not evenly spaced as the other 4cyls such as the 4G63 (DSM motor) or the F series motor. Me and my friend with the laser took pics of the DSM manifold and our exhaust ports, they just wont line up.

DSM Manifold (Aftermarket one, but stock one looks similar)

3G Manifold (Look at the cyl 2 and 3 outlet)

Civvy: IF u read the turbo threads or searched for it, i have mentioned it numerous times.

pwn3d, there is no way in hell that manifold will ever fit on our cars! thanks praveen lol...

Smufguy, the question here is not whether it fits the A20A, but if it fits the B20A...

That mani never fit either. But the outlets did and thats what where looking at. I never saw that pic of my mani before

that was from Seans website.... when it used to be up and running.

So basically, forget the flange for a minute. u guys are saying the runners are the same/similar to the B20's (hell, they must be if the 3gludes are using them).
So to do the job perfect, we get the manifold and have a shop swap the flanges?
We dont have DSM's over here, so it'd have to be the evo's right?

bobafett

you cant just swap flanges, because the runners will till not match up. you would have to fabricate an adapter that makes the dsm (equally spaced) manifold change to the a20 (v8 style) head... this would be a huge PITA, and you might as well just make your own log style manifold for the same cost, and have better performance. or build a real manifold like seans, but it does take some more time and money...

He's talking about the B20A not the A20A

Funny you should mention V8, before I made my header I looked at a few V8 headers to see if they'd line up, but even if the flange wasn't an issue the tubes ran sideways instead of straight down, so that was a big problem.

dsms have different manifolds going on the year and it will not fit our carz

Just curious, Mike; what side exit V8 manifold did you find that lined up with our exhaust ports?

I didn't find one but I notticed what bobafett mentioned about the A20 being V8 style in how they had the center two ports paired and the outer ports spaced in the same fashion as the A20... what I was going to do if I got a header was cut the flange between 4 and 3, & 2 and 1... then adjust the spacing that way, what I didn't like with the ones I looked at was that they would all be side exit unless I got a shorty header. also the port shape is different... round vs oval and the flange will need work to get mounting holes made. The mounting holes were anouther big factor for me.

I was asking mariobruke for a cast iron manifold cause I was going to try to mod a cheap V8 header pipes to the Stock flange.
I'll see if I can dig up some gaskets.

I can always grab a gasket and

I regularly strip and oxide blast headers at work, i'll have to get an a20 gasket so i can start checking, i have seen a few hooker headers that had a damn similar port spacing to ours.

[FONT=Arial]WHAT IS YOUR OPINION ON CHEAP SWAPS OR POWER UPGRADES I HEAR THAT A TURBO A20 IS REALLY KICK ASS OR IS IT RELIABLE
IS IT POSSIBLE TO ACCOMPLISH A B18C5 SWAP SOMEBODY LET ME KNOWH

come on now... read the faq.

its EASY to do the swap if you have the right parts, which you cant get anymore because the company who makes them is out of business.

enjoy.

repoman: Welcome to the Board. Read the Faqs and How-tos and all the sticky thread in the Thecnical and Performance setions. This would help you from future flaming just in case you ask some repeated stuff.

DSM manifold is not a bolt-up for the 3g prelude. If it was, there would be a lot more turbo'd preludes. Everyone i've seen on preludepower.com with turbo is using a manifold made by Gladman or one of the other members. i believe the ports for the DSM manifold may line up, but you need to drill new holes to make it fit
