What would be every thing needed to swap in a B20 engine into a 1992 gs teg. I knw tht harness and probabley ecu's need to be changed but is thr anything els such as axels or cud the stock ecu still be used?

 

you can use everything of your ls on the b20 same wiring harness and tranny and axles and the ecu the b20 is the same thing as a b18

 

thanks man i new tht the B18A1 and the B20 wer the same except tht the B20 was a little bigger and had more torque but i though ti had to chang wireing and other stuff.

 

Another question the B20a and B20b wud still just drop right in or wud i just go with the B20b?

 

b series will bolt up to a b series.. lol...

any of the b-series will drop right in.. if you are going from b18 to b20, your answer is yes to pretty much everything.. its just a b18 with a bigger bore

 

oh yeah.. i forgot.. except the b20a5.. that is NOT a REAL B series.. it came from an 88-91 prelude 2.0 si

its a wannaB20.. HAHAHA.. its more like a dual cam f series than a b series.. b20b or b20z only.. if i remember correctly

 

Lol thanx yosha so th ecu and wireing and everything shd work like u guys are saying sweet. The reason tht im dropin in the B20 is cus my B18A1 bent a valve so the head is bad and a friend of mine is giving me his full B20 for $100 so i just felt like droping in a newer engine with less miles and a little more torq

 

DO IT DO IT DO IT!!!! what a great ****ing deal..

you are all good.. ecu and all.. just bolt in, and enjoy a more torquey motor

 

b18a1 is obd0 and a b20 is obd2....

 

See i knw tht so i thought i had to get a differnt ecu one thts obd1 harness

 

no.. you dont... you use your b18 dizzy, intake manifold, and sensors, and put them on your b20...

 

everything will bolt up correctly without modifying anything

 

x2

 

Thnx guys thts legit i knw a bit about hondas u knw the normal D series and some gsr stuff but i like B series so much more, but i got so much to learn still on the tunning and swaping aspect of hondas.

 

he has a 92 b18a so its obd 1

 

b20b more of a torquey motor while a b18 is more of a high rev top end motor

 

So just to be 100% clear b18 harnes sensors and manifolds all change over to the b20 during the swap. Or do I have to use the b20 harness.

 

This question was answer already but ill help you out.

Get the b20b or b20z. Your only going to use the block and head. Transfer your intake and exhaust manifold from your b18a to the b20. Use every single sensor and distributer from the b18.

You mention your getting a b20a. That wil NOT work on your car so don't buy it at all.

 

B20A's are from preludes. You can't use that in a civic/integra

 

you can use the sensors from the b20, the plugs are all the same iirc. you may have to run the iacv from the integra. you will need to swap the drivers side mount to the block from the b20 to the one from the teg. the rest is great advice, both manifolds, the throttle body, distributor etc are all from the teg. you may want to swap over to the teg dipstick too.

you can run the integra ecu, but may want to raise the fuel pressure a bit as the b20 can run a bit lean at cold start and wide open just straight up off the ls ecu.
