Like the title says im sorry if this is a dumb question. iv serched but cant find what i need to know. Being that im in no way a mechanic, Im taking on my first camaro project. Its a 1992 rs had a 305 tbi setup and im looking to go to a tpi 350. Will this be a plug and play operation or am i going to fab the wiring in any way. Please help.

 

If you replace the entire wiring harness, it should be fairly plug and play hardware wise. They use different ECU's, different wiring harnesses, and sometimes different sensors.

 

yeah thanks I really, really don't want to rewire the car, so performance wise can I get decent performance from a tbi. Im not a racer, im looking for a nice sound, burnouts and decent fuel milage, not much more than that.

 

been doing more searching and my head is spinning I guess im looking for a drop in and go setup while getting good gas mileage. so when my eyes get uncrossed I will be doing more research. any suggestions would be great

 

Does some research in the tbi sticky posts very informational and a lot of reading. Good luck

 

To swap from a 305 TBI to a 350 TPI as previously answered requires modifying the existing or replacing the Wiring and ECU plus alot of time and tools.

If you just want better sound, just put headers on with a better exhaust. It is easier than trying to swap motors.

If your not a racer as you state it.. Then you don't really need better power. The 350 a little bit better, but requires alot of work that you already stated you that you are in no way a mechanic..

The 305 should be fine if all you want for Burnouts, Sound and Mileage.. Just change the exhaust.

 

You could always put a 350 in and keep the TBI
Some easy swap parts required ( a 350 chip in your existing computer , etc ); no wiring changes

 

55#hr injectors for a mild 350 and a anlu eprom

 

Im on the same page as most of ya im going to find a complete 305 do a mild cam swap, headers, exhaust and let her ride. maybe I can make the ocean city fall cruise.
thanks to all who have replied.

 

Going from Tbi to Tpi. You have to re-pin your harness where it connects to the ecm. Not very difficult. You will need the 350 knock sensor, ecm,chip,injectors. You may possibly have to change the fuel pump too.

 

the guy I got the car from said he has a complete tpi setup for 100 bucks
I haven't seen it yet so I don't know what his ideal of complete is. and it sounds like with all the great knowledge on here I could do this..

 

He could be talking about just the actual intake. Lower manifold,runners,plenum. You still need fuel rail,fuel pressure regulator ,injectors and Throttle body.Then there are the sensors.

 

I guess the big question is what is easier tbi or tpi

 

Tbi but performance wise tpi from what I've read is better

 

stock to stock ,yes tpi is better,but tpi won't make power up high in the rpms like a tbi would. I would stick to tbi if you already have that.

 

They are both easy to build.

TBI will allow for higher RPM's with less Torque than TPI
TPI will allow for more Torque than TBI but fall on it's face at higher RPM's

Both require a computer and basically same components.. Wiring is a little different.. It is a matter of preference.

 

being the car is just a roller and I have no tbi parts and I can get the tpi set up I might as well try that route first, so im off to the stickies to do some research. man I cant wait till it get warmer

 

It takes me several hours traveling on I-81 to get to Maryland... Don't ask me how much I hate cold weather. Hell froze over and without Windchill it's 18 degrees.. I live 24 miles from Canada.

 

yeah that sounds like that would suck..

 

I have to goto the garage to fire up the furnace today as I should start putting the roll cage in.
