If I understand you correctly. I think you need an OBD1 distributor. I'm using one from a 92 Integra (B1.
Are the connectors a grey color?

lordbutz i just installed the tre-341 fuel pump and if you dont reuse the stock filter attached to the pump then when you get below half a tank of gas the car will die when you come to a stop or even tap the breaks hard. perhaps you could add this to the op to save some other people time.

Yep. Its like an aftermarket maní without iabs. Just find that matching gasket again before you open the im. A túne will make it run like a champ!

Definitly. A túne will make it run like a champ. Its like getting an aftermarket im without iabs. Before you re-open the im, dont forget to find a matching gasket again. Good luck man!

Then just plug the remaining hose you just cut into the backside of the IM were you removed the line... the black iab box is now... totally disconnected. The iab plates will now be operated without the black box...

Front page edited and updated

I had to delete a lot of missing information and old information regarding this thread.

As of the date of this post, LSDMotosports.com no longer supporting the 3rd gen community. They have moved in a different direction and have since stopped fabricating anything.

You may try and contact them, but I make no promises or guarantee's that they can help.

They may still sell the universal parts for turbo charging but not 3rd gen specific anymore.

b20a bored to fit 83.5mm b21 pistons.
b20a intake ported and polished as well as gasket matched to the head. head got same treatment.

here is my question. the car will be possibly retaining its iab's. i have an ecu thread, but not getting any responses there, so i will try here.

for the turbo'd ludes, how did you get the iab's to work after getting tuned, and what ecu was used to do it?

i spoke to blake(98vtec) and he told me that the pr4 and the p28 do not have the ability to control the iab's. unfortunately, he is a 4th/5th gen tuner and i don't doubt his abilities, but i am gonna need a tune, and the car is going to get turbo'd at a later date, so please help me out.
if you want to keep the iab's you will need to use a p72

Ok to clear things up.

All that needs to be done is to swap all accessories from the B21 to the B20 head and block.

No need to do any wiring since the B21 is already OBD1.

So we don't have any confusion this is what I mean:

Take the B21 out and transfer:
Intake manifold
Exhaust manifold
Powersteering pump(they are both the same so really no need but its your choice)
Engine harness

Then plug everything back up.

1funryd I added more information on using an H22 Treadstone Turbo Manifold for the 3rd gens.

Information is in the middle of the first post.

Some people did not have to do that, they fit just fine. But it depends. If you cant get them to fit, then I recommend boring out the rubber O rings to make the fit.
