B20b or b20z don't really handle turbos that well due to thin walled cylinders.
It hsa 126 hp base model and 146 turbo.
B20B= 6200 rpm B20Z= 6800 rpm
280hp
In order to get a ecu wiring diagram from a Honda b20b it is best to visit a local Honda dealer. The service center maybe able to assist you with providing you with the diagram needed.
no it is nard hard considering its a B seiries but you will ned a p28 ECU , aftermarket B series to 88-91 hasport crx mounts, a standard tranny and a complete B20B swap not a longblock or shortblock. - *PHaZE II* -
underneath the air intake piping, above tranny. passenger side
Why would you put a B20B in to a CRX, that's the engine out of a CRV, and yes, it will be a pain in the ass. Why not do one of the common swaps such as a B16 or a B18. If you can get your hands on a JDM B18 Type-R, that should be more than sufficient and a lot easier to pull off.
its against the firewall. looks like a black plastic cylinder, and the fuel feed line from the intake manifold is connected to it.
any bseries motor is a direct swap, b18a/b, b16a/b, b18c5/c1, b17a b20b/z, some will require different ecu/ jumper/distributor but all of these require no modifications to the chassis.
you can fit the D16sohc vtec (1.6el) B16a (civic SIR/Si in US) B16b (civic type R) B18b(ls integra) B18B (gsr integra) B18c5 (typeR integra) H22a (prelude) B20b (honda crv) K20 ( rsx type s) K24 (tsx) J35 (honda oddesy) J32 (acura tl/cl type s)
The B20B or B20z Engine from the Honda CRV is not a very good platform if you are looking at building a serious engine. These engines were not produced the same as the B16a or B18c blocks with the same quality and tolerances, So inherently the castings differ alot and tend to be very weak! Any good B18c block will be fine and in particular the B18CR. By changing the pistons to 84mm you will have a 2 litre engine which will benefit greatly from more Horsepower and Torque :)
