By the way, It looks great. That engine is so awesome when you get the lift cam doing its thing properly.

I've made the post regarding the mounts. Waiting for admin approval. But yes the front frame had to be modified a bit. The tranny didnt fit in, so we had to hammer bend the frame right above the transmission area to make an inch of room for the bigger transmission.

What about on the pulley side. Did you have to mod the frame there?

He didn't say that he switched from a manual to an auto transmission, instead he stated that he is using an auto trans ECU with the manual c60 trans...

Ok, question still stands.. which shift linkage did he use. Yaris or celica?

I made a detailed post regarding the mounts a week ago. Admin still hasnt approved of it ADMIN HELP!!!

I'll make sure and let you know, But as far as I know we used the cable and shifter from a Corolla.

Deleted my post. It's now irrelevant.

Keep us updated on this one, thumbs up to you sir.

Guys I need help with installing an OBD2 port. How do i install it to the new ECU? Anyone know how it is wired?

Did you get your hands on the wiring diagrams for the car that you grabbed the ECM from?

There are numurous wiring diagrams available online, for the 2001 celica, but I cant understand the whole concept of how the ECM is wired to the OBD2 plug. Need help with that.

Updates:

Got the cooling system sorted out. Initially there was no thermostat installed and the temperature sensor was not plugged to keep the fans running at all times. Now 82C thermostat has been installed and temperature sensor has been plugged back on. As a result the LIFT is working perfectly now and the car accelerates like crazy when LIFT hits.(Video coming soon)

AC condenser has also been installed. But having problem with the AC compressor. The 1KR compressor which was fitted on this 2zz has cracked . probably the reason being the smaller pulley size. And i cant install the original compressor because there is no room for a larger pulley. Someone advise?

Wiring to the OBD plug is typically very trivial. That vintage is ISO9141, so there is one (K line) wire that is the communications wire.

Pin 16 is constant 12 V power
Pin 4 and 5 are grounds
Pin 7 is SIL, which is a direct connection to the ECM
Pin 13 is TC, which is a direct connection to the ECM

An OBDII reader communicates with the ECM via pin 7, which is the "K Line". For a standard OBD reader, just 4,5,7 and 16 are needed. Pin 13 is a toyota specific diagnostic wire.

Thanks for the response.but on the ECM end, where will all these wires be connected? or will only pin 7 be connected to one of the pins on the ECM?

7 and 13 are the only ones that connect directly to the ECM.

Ok. And are there any connections to the different sensors of the car...or does pin 7 and 13 provide all the data from the ECM to OBD2?

With ODBII the diagnostic tool just talks to the ECM and the ECM does all of the talking to the sensors.
