Hi all,

I purchased a 1984 CFI car and have driven it for a while. I am doing a changeover to put a TPI from a 1985 Corvette in the car. Has anyone done this type of changeover and does anyone have any input?

thanks,
Brian

well... other than it's more work than it's worth.

I would consider saving the time and effort and upgrade to something with power potential.

hell, you can do a lot to the Xfire that will get it up to over 300hp... with no effort.

I chose a different route, I thought about doing the changeover also but I quickly changed my mind when I realized how much work was needed just for an extra 20HP, then once you get the TPI on you will still have to do/buy more to get the horsepower out the motor. You could just get a crate motor or build up what you have already depending on how much HP you want. I went with the build up method ie heads, cam, bored TB's, roller rocker's, 3.54 rear gears, Built tranny with 2800 stall TC, MSD, and so on. I have just over 300HP (300.9) to be exact to the crank, but that's alot better than the stock 205HP. I wish you luck in whatever you decide to do.

Alcee1 is the resident poster child for what CAN be done with the Crossfire.

BTW, his C4 is BAD to the bone!!!!

The bronze/gold exterior matches nicely with the tan interior... he also has a wood dash kit - the ONLY one that I have ever seen that looks right.

Just a lovely ride, all the way around. Sounds awesome, too. :thumbright:

I'm also sticking with the crossfire. I'm currently having an intake ported and modified. I'll be adding 1.6-1 rockers. The cold air mod is done w/K&N filter. gears are also in the works. Switching to TPI would require changing the harness also. Just too much work for not enough gain IMHO.
