Not all 2J’s are dyno queens with huge turbo with nitrous i know plenty of guys running T6776S turbo’s making 800+whp and running 10’s with almost no lag
burnyd the previous owner of my car was making 466whp on the W58 trans. I had it retuned and re-dyoned last year and it made 446 on a more safe conservative tune. When I bought the car in august of 07’ I took it to the drag strip pretty much every weekend that year and last year. I didn’t drive it much this summer due to me adding some fuel upgrades etc. I don’t daily the car so that helps keep the stress down on it. When i do drive it tho i drive it hard. I’ve never had a trans issue yet. Knock on wood.
Yes my car is a NA-T car with a GTE block and a GE head
