Now that I have hit 14,100 miles... (228 post service) I'd like a little more bang! Before I say screw it and slap on some turbos, What are my real options? High flow cats? After market muffler? K&N filter? ha... I have some 4 hole injectors waiting to go in but maybe a package deal of parts Thanks in advance
Personally, the exhaust is the best place to start. You get the most out of it in my opinion. Since you can actually hear and feel the difference compared to the bolt-on and go choices. I came across this video of a Mondial T has our decat and exhaust installed! So, you have an idea of what to expect with Tubi!
Sounds like a plan. Shoot me PM if you need any help figuring out which Tubi exhaust it is. Tubi offers 3 different exhausts for the Mondial T so it can get a little confusing.
I agree that exhaust, cat delete, and K&N filter are good places to start. Probably yield you another 10-20 hp. It will sure feel faster, but these are old cars, not much you can do without more serious mods. Check out the 348 forum, there is a ton of stuff there done to push up power! Cheers
Definitely do high flow cats, and performance exhaust. I have them and my exhaust, a Stebro - no longer available - sounds perfect.
Tubi is hands down the best thing I’ve done. Literally transforms the car. I have high flow cats as well.
Replace the cats with 2 down pipes would be the least expensive option to get most power gain. Add the other stuff that is mentioned and you get more
I second that. My Stebro sounds great. I installed an Hyperflow after noticing a strong loss of TQ in mid range w/o Cat. I gladly exchanged the few HP gained at 8,000 RPM for more TQ at mid-range. That AND I pass smog any day.
A buddy of mine just picked up this 1982 Mondial 8 with a vortech supercharger on it. We are currently in the process of rebuilding literally everything on it because it sat for a number of years. Will post pictures of the progress and updates. Image Unavailable, Please Login Image Unavailable, Please Login Image Unavailable, Please Login
Sounds like fun! However, depending on the condition of the motor is might be better to replace it with a 4-valve and then add the supercharger.
Motor is in pretty good condition as of now, but if we run into issues we can just swap a QV one in. Don't plan on trying to rebuild the 2 valve if it goes. But before we started ripping it apart the 2v worked quite well with the supercharger.
"Goes until it blows" The only weak point with the 2v, as I recall (from personal experience), is the cam belt drive pulley bearings.
Already replaced, as well as all the rest of the pulleys and belts. Next up is replacing all the soft lines and some hard ones, with the best quality we can get our hands on. Then its on to gaskets, springs and anything else we think needs replacement.
