Skunk2 Racing Intake Manifold

[StUpiD8000]

will this work with our cars?CLICK HERE (http://www.optauto.com/webstore/product_information.asp?number=S2-307-05-0280&variation=&aitem=5&mitem=12&back=yes&dept=494)

Actually I believe so. I remember reading somewhere on the board that the B-Series intake manifolds will fit on our cars with some port matching.

[night]

thats funny.
thats an ITR intake in the pic.

which btw, is better overall than the skunk. especially since its cheaper.

[PhydeauX]

Yes it will, you will have to modify the flange slightly but it will work. Some of the top mount holes need to be redrilled, with an a20a gasket as a template it isnt hard at all.

What would be a better thing for performance? to buy and customize that Intake Manifold, or to leave the Intake Manifold stock, and will any B20A Intake Manifold fit on it with the same modifications? If so I'm in! 88LXI I love your car man.

[PhydeauX]

That depends on what else you are going to do to the motor. That manifold is going to give a boost in the top end, if the rest of the motor is stock then that not going to be that big of a deal. If you have a cam its going to be a much bigger diference. It'll be a low end sacrifice, but thats the price you have to pay for power. If I'm not mistaken the b20a has the same manifold as the a20a, carrot didn't you cross reference them and get the same part numbers? Any b16a or b18a manifold will fit. The row of bottom bolts are the same and the ports are almost the same, you have to drill new top holes then the manifold will go right on. The b16/18 ports are slightly larger then the a20's and the whole thing will benefit from a good portmatch, but its not necessary if you don't want to pull the head (taking the efi manifold off is 10 times easier if you take the head off first). You'll need the throttle body from a b16/18, they are bigger then the a20's. I don't know about the fuel rail and injectors, I did research on swaping the manifolds, but I didn't go that far.

Well I wanna install a new high perf. Cam and cam gear, I want to bore the engine over to 2.2L hopefully with JE Pistons and Crower Cams everything inside the engine, I wanna do a complete make over inside the engine with high performance parts, thats when I get the money, once that happens I'm gonna pull the engine out and rebuild it completely. So I'm gonna buy everything from the Intake Manifold, to the internals to the header, then drop the engine back in.

[PhydeauX]

If you're going to do all then the yeah go for the manifold while you're at it. Build it to rev and you'll really benefit from the manifold. If you are going to do it in stages I would start with the cam and gear first. They'll give you alot more with the stock intake then that intake with the stock cam.

Well if the B engine Intake manifold will go on it, then most likely the B engine's Fuel Rail go on it. I'll have to test my theory!

[carotman]

the fuel rail fits with an adapter bracket

As for the B20A intake manifold, the JDM B20A shares it's manifold with the A20A. However, the Throttlebody is bigger on the B20A.

[2Fast_Fiero]

That would be a good thing tho right? Bigger throttle body on a new racing intake manifold? What would I need for all of that to work? Throttle Body, Racing Intake Manifold, and High Flow Fuel Rail? Whats these brackets you speak of?

[1988starter]

That could be damn good

[1989 DX R]

Can our blocks be bored? (No not that way) I heard the cylinder walls were too thin.

[jteuton]

i don't think 2.2l is realsitic.....the block walls would then be too thin for high performance applications

[jteuton]

maybe if you sleeve it you can get away with it???

[2Fast_Fiero]

I just thought about that today when I was looking at my block, it might be too thin to bore.

[2Fast_Fiero]

So for what engine should I get my Intake Manifold? B20, B18, B18???

[Jims 86LXI HB]

And the most you can hope for with stroking is 100cc, funstick checked it out a long time ago. Not worth the effort and $$.

[night]

a skunk manifold is best with a GSR head. im not even sure if they make them for B16 heads. they didnt a year ago.
for a b16 head you want an ITR manifold

[2Fast_Fiero]

WHAT ABOUT MY A20 Head??? I don't have a B16 or B18, I have a A20, I want to know which one will fit my A20?

[1989 DX R]

Well, none of them without some modification.

[toastyghost]

MSIAccord_LXi: Here's how you tell what manifold will work... If you had to ask that after reading the thread, DON'T ATTEMPT TO MODIFY AN EXPENSIVE ASS MANIFOLD!!#@@!1 JUST SEND IT TO MEE

[2Fast_Fiero]

I know how to modify shit, but I don't have the money to buy the wrong fucking thing, I want to buy the right one and then modify it, so which one is the one that bolts right onto our head with mod's??? And don't say any one, Just tell me the right one, Is it the B20 manifold? the B18? Which one will work better?
<Edit>Ok Ok Ok, what I'm trying to say is, which intake manifold will fit on the A20head the best, I know everyone will have to have a mod done, but which one will be the best for a Highly Modified A20 engine? Because I plan on going all out and I realy don't want to spend money on a High Perf intake manifold thats not realy going to work, if you guys say its a B20, I'll go out and buy a B20 High Perf. Intake Manifold, I just want to do this right so I don't fuck up and buy something that won't work and I can't get my money back.....Thank You

What cams can we get for our cars?

Get a JDM B20A performance intake manifold. It will bolt on without modification.

[2Fast_Fiero]

Thank You Soo Much Site, that is what I was looking for, now trying to find one for a JDM. lol. ohh and Stupid, if you can't find a cam for our car, you can get one made from Crower Cams.

[StUpiD8000]

WHAERE CAN WE START LOOKING FOR A JDM B20A performance intake manifold? AND AS FOR THE CAMS, DO YOU KNOW HOW MUCH THAY ARE? I CANT FIND ANY NFO ON THEM?

[night]

well i posted that kinda blindly. ive been on clubsi a lot lately :).

anyway. the ITR's are cheaper. like 220.

[PhydeauX]

If you're going all out I'd recommend the jdm b18c spec R manifold if you want to stay factory honda, or the skunk or ITR if you'd rather use an aftermarket. b16a b18a b20a, as far as mounting the manifold it doesn't make much diference which you're going to use, they all have the same ports and its no trouble at all to modify the flange. (The b16 and 18 have slightly larger ports, but if you're going all out then your going to be porting the head and that won't make a diference).

http://68.81.205.164:3000/accordpics/BseriesToA20.jpg

Thats a b18a gasket sitting on an 88 lx-i manifold. The 2 red dots are where the holes would have to be drilled if a b18a manifold were used. The stuff on the left corner of the gasket is for the water jacket, you dont have to worry about that when the manifold is fitted to an a20. If you were useing a b16a manifold then a 3rd hold in the center, the one that has the blue dot, would have to be drilled as well. The b20 requires no modifications.

Out of the list I think the b20a manifold would be the worst choice for a high performance engine (with the stock b18 adn b16 being in close second). They all use smaller plenums and longer thinner runners to get better low end torque and driveability. The type R and aftermarket manifolds are designed to let the motor really breathe up past the 7000 range and make alot more power up there.

Well, I just did some research on those manifolds, and they aren't anything near high performance, just from my readings, but the Venom and STR Intake Manifolds are THE all around best for High Performance engines, The JDM and USDM Honda Manifolds are only good for people that want to stay with Honda and still have some sort of performance. But I guess I'll get the Venom B18 Intake Manifold.

[night]

i'm tellin ya, you cant beat the ITR for the money. it flows more than just well enough for built NA CRVtecs. thats 2 liters @ 9k rpm. a lot of air.

and PhydeauX, something i actually know more about than you :p. unless you just woke up or something and arent thinking right.
the B16, B17, and ITR (B18C5) are all the same head.
the B18A, B18B, both B20's, and B18C1 are all the same intake ports.

so basically there is the B16 head and the B18/Gsr head. the B16 (ITR) manifold will not go on a GSR without modding.

so you should figure which is the closest to start.

[PhydeauX]

Its the water jacket thats is the big diference between the b16a and the b18a. Don't have to worry about that if you're putting it on an a20a. I knew that the b18c5 and the b16a had the same head. The b18a/b and the b16a do have similar ports, neither are similar to the b18c1. I have a b16a manifold and b18a gasket in my junk collection. I've never looked into the b20s.

andy

[PhydeauX]

gg double post

[night]

the B20's are an LS head.

[2Fast_Fiero]

LS?

[StUpiD8000]

OK what intake manifold will bolt up to the stock head? Im not looking for much performace, more for show points. but some hp gain

[PhydeauX]

The b20a from the jdm 3g accord is the only one that bolts right up. It looks exactly the same as your manifold does, most honda efi manifolds look like that. If you want to show get some aluminum polish and elbow grease and polish up your manifold.
