Trip to track after 4:10 gear swap.

Been watching your Youtube vids - interesting despite the timeline. I’m looking at the 4:10 set, CAI, tune but I’m torn about upgrading the TC stall. Just floated this question through the PI website. 3600 stall keeps jumping out at me for some reason. Used a PI converter - transgo shift kit on my previous ’98 GT.

I went with a PI 3500 stall with 3.55 gears only because I got a great offer on the converter that I couldn't pass up. Took more gas to get off the line around town unless I was loading the converter up above 2500 rpms but it pulled well once it got moving and took some heavy tune tweaking to get it dialed in. I stayed 3.55 gears for a long time since I daily drove it for years and did 4.10 once I got another car. Honestly, if you are considering a converter, go with a Circle D unit and stick with 2800-3200 range or talk to the tuner who you get a tune from. I feel 3500 is okay street wise IF the car has more than 300rwhp, anything less and its sluggish around town.

Thanks for this. My ’98 TQ peaked at 3500 stock and a 2800 TC (2200 stock?) was recommended - loved it (many other bolt on mods too). Reading where the TC stall should be 500-700 below Peak Torque - around 4250 on our cars stock? I’m consulting as many people as possible - thanks for the tips!

To a point. I don’t think I would want a 6,500 stall on mine if they were to build it LOL

Hoping Jtrip will give us an update.



My car is at MartyO's shop being 'updated' at the moment. I installed a K&N CAI myself a few weeks back - highly recommended even if one does nothing else to their Marauder.


What MartyO's shop is doing to my car during this visit:


Rear Cylinder Head Cooling Modification - new custom COT filler cap

FRPP 4:10 gears

FRPP Girdle Cover

2800-3000 Stall Converter

New Fluid Pan with Drain Plug

Jmod - 88grandmarq coming over to MartyO's shop to perform this modification

Custom 93 octane tune


I'm excited and looking forward to the results. Similar mods were performed on my '98 GT many years back and the results were way better than expected.


Future 'wish list' for the Marauder:


ADTR Procharger Kit

Big Brakes and Suspension Upgrades
