Noway dude, everything else you got correct except the redline part. Red line is definately the same. My 91 redlines at exactly 6800 and cuts off at 6900. And I don’t need glasses

both of you are wrong.

90-91 redline at 6600.

92 - 93s are a little higher…I believe around 68 - 7000, and G3 integras redline at either 7 or 72.

hmm weird max, i know for a fact that my redline is higher than 6600, more like 6800 and i know my fuel cut off very well at 7300 with that damn skunk2 manifold i had awhile back, i would hit the cut alot cause the damn thing would keep pulling and pulling.

my fuel cutoff WAS at 7000…now i shift at about 7400.

:D:D

looks just like my 91. 6600.

I just bought a B18B1 Head and it didnt come with the fuel rail, cam gears, and IACV… Can I use the Parts off my B18A1 ?

There is also a fuel rail off a 94 GSR for sale on Ebay. Would that work on the 94 LS or could I just use the one off my 91 LS?

Some one help me please…

hey max, do u know by any chance how a b18b intake manifold would fit on a b18a?

just port & polished my b18b intake manifold… and to what i see… everything will line up… but the only missing component i dont have is the FITV, and it doesnt look like it has anywhere to bolt into…

do i need a b18b throttle body to work with the b18b intake manifold? or can i use the b18a one?

my intake mani is a b18b…the heads are pretty much the same in terms of stuff bolting up.

tbody doesn’t matter…

[SIZE=4]pic has now been fixed.[/SIZE]

so the b18b intake manifold doesnt need a FITV?

pic is now broken.

pleeeaassseee fix, I’ll be swapping the head and IM soon, I’d like a reference.

it’s simple, as for the bolt in… but vacuum lines are easy as well… i think i have the pics on my computer… would u like me to email them to you? if hotmail can handle it…

try email… warric_k@hotmail.com

the pic isnt really neccessary, since i just did a B18B manifold on my B18A. the only thing i had to do was tap off one coolant line that goes to the FITV under the TB

and extend the stock map sensor wires to go to the B18B map sensor (and no i havent thrown any codes)

i havent taken any pics of the finished product yet. thats coming tomorrow.

other than those two things, everything else lined up perfectly. the vaccum lines are easy. if you extend the wires from the map sensor, you can forget about that vacuum line that goes from the stock map sensor, and just move one of the short lines that goes into the back of the B18A IM to the one open spot on the front of the B18B IM

about the redline thing, I think you guys need to clarify whether you’re talking about redline or fuel cut-off.

The 90-91 Integras has a redline of 6600 and a fuel cut-off of around 6900. I know this from my own car.

Not sure on the 92-93’s.

The 94-01 Integras have a redline of 6900, and fuel cut-off around 7200rpms.

i just happened to rev my 91 to past 7k today… twice…

then again, it was in neutral, and the tach might be off

Heres some better shots of my manifold from both sides


How does it feel with the B18b manifold in? Any difference?

for me, it runs smoother, but i feel it pulls the same.

i got a request for the pictures i had. i rehosted them, heres E-DA9s picture as well…

Thanks man. Got them saved on my hd now.

Also can anyone tell me what this guy did with those round things that the vaccum lines go into that are on the firewall next to the map sensor? I want to get rid of mine as well. This is a pic of Mango’s engine bay i saved a while back.

so u can do the head swap and keep the car obd0?
also, if i did the swap, is there a way of cleanin the block and stuff while the head is off?
