Doing my first swap. Just want to know if my 86 350 tpi fit in my 91 camaro rs 305 tbi?? and what changes i really need
I NEEED HELP!!!!!

 

It will fit. You'll need the entire pass side harness, the ECM, etc. to swap the TPI in.

 

SO IS IT BETTER TO JUST KEEP THE ECM FROM THE OTHER CAMARO TOO. OR BUY A NEW ONE

 

Keep the ECM from the L98 donor. Just started my LG4 carb to L98 swap today myself. Pulled TPI engine from an '87 IROC-Z.

 

THANKS A BUNCH MAN... AND IM GETTIN IT OUT A 86 IROC Z IM TAKIN THE REAR POSI AS WELL IS THERE ANYTHING DIFFERENT BETWEEN THE MOTOR MOUNTS.

 

As a California resident are you aware that you cannot legally swap in an older motor? If you do this swap you will have to get it approved by a state referee before you can smog it. The ref will check block number and ecm number. they will also check to see if all the sensors are there for a post 1990 tpi. such as map. By the way...the Camaro data page here at tgo says that it is rumored that only 50 1986 l98 thirdgens were built. Are you sure its a 5.7?

 

yea i know my friend did tell me bout that i will just never be able to have it smog legit ill have to do it on the side you know how that goes... and yea i checked that too so it may have sum what of a issue they said they where made for test cars..

 

and as the sensor issue will i have to just transfer all the sensors over and should i buy all new ones???

 

350 Tpi's did NOT come out until 87... I would double check the block numbers.

 

yea its a 350 cross fire tpi 5.7L from a 86 IROC z and its going into a 91 camaro im in the process as we speak..

 

The motor mounts are the same. As for the sensors, I was able to run a scan on my donor with no codes thrown. I'm planning to use the original sensors. That said, a new O2 sensor is never a bad idea, followed by a knock sensor since its a coolant drain if you have to do it later.

 

COOL THANK YOU VERY MUCH FOR ALL THE INPUT... I JUST BOUGH FLOWTECH HEADERS AND THE O2 SENSOR IS ON THE RIGHT SIDE NO PROBLEM THO... IM ALMOST DONE WITH IT ILL PUT PICS ON SOON
