OP, the simplest way to get close to the TRX/R is just a good intercooler and an E50 tune from Goose. You can then add a hpfp, full E85, and get a few more hp. At that point you’re definitely faster than a TRX when you account for weight.
If you wanna go the much less simple way, and pump gas is an absolute requirement, you’re gonna need a lot of stuff. Namely the biggest turbos and intercooler you can possibly get. You’d want to keep boost low if you wanna have any chance surviving at on pump gas at the factory compression level, otherwise it’ll be a bad knock knock joke.
This 100% TFL a while back on YouTube had a Gen 2 w/ a tune/intake/IC go up against a TRX (& another Raptor I think a stock one?) & the lightly modded Gen2 was RIGHT there off by a couple tenths BUT it was also lifted & riding on heavy ass 37”s!!
