What is needed for 400+hp sr20det - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

During the last event of the year for myself, my stock sr20 started knocking. Bought one that is built for 500+hp but would like to be around 400-430hp. Basically just wondering what it would take to get to my goal. (turbo, injectors, etc.) Thanks in advance, happy Thanksgiving!

here is an excellent thread:

400 is a bit much, you're probably better shooting for 300-350 for now

Just get a manual boost controller and turn up the T25 bro

I honestly don't get how people say that their engine is built for a specific hp. I mean the parts I built my engine with should support 1000+ hp, but who actually determined that or what determines that? If my turbo supports 300 and the engine blows with all the parts in it does that mean, the engine really could only support 299hp? Hmmmmmm!?
The key ingredients for a 400hp sr engine is a good tune, enough fuel and air. So why people tend to ask this question and be serious? it's not really something someone can say specifically. That will guarantee you the 400hp engine you want. 400hp from a big slow spooling turbo is still 400hp although 7000rpm might be ok! 400hp at 4500rpm, much better IMHO.
After the engine is built, you take advantage of the parts installed to make the power you want, can handle or are supported by. I like to find the weakest and build, tune around that.
Ahhhh what was the question again? Oh!

How many regular miles you got on it? None, it takes premium!
