I just tried a td04hl-19t on a stock engine and was very disappointed. It made 220whp with meth. two weeks was all I could take. I am breaking in my new stroker on my vf48 but I went with a tomei 7760 (20g). Ill be happy to sell you the tdo4hl-19t. Meth isn't bad ether I just fill it every 300-400 miles.
