Toyota 4GR-FSE. Makes a little bit more power than real thing but still good fun. Sounds pretty similar to real one.

Similar D24 I first made. Changed ignition timing, Idle is slightly lower and makes more power with 190hp and 188lb-f...

Attempted making the D24TIC engine based off the RB26. Not the fanciest thing on here but thought I'd give it a shot....
