Could do close to 400kW but those valve springs are very soft and you'll end up with valve lift.

Has happened to 2x SRs I've tuned with big boost. Torque/power falls on its face when you add boost and the motor hesitates as though it's misfiring. New springs in, problem gone.

Thanks mate

Keep in mind buying parts is easy.

Bolting shit together is easy.

 

 

 

Buiding an engine that hangs together and makes decent power is not easy.

400kw at the wheels? should it be safe 300rwkw?

depends on the turbo, a 180SX I did a while back had a GTX3071 with 0.83 rear on a 6Boost TS manifold merged into a single 45mm did 351kW at 27psi. That's with super lazy timing as well. I think it would have made more, but I didn't want to push it any further as it is a track car.

So do if i got a gtx3071r .63  would it spool quickly and put out about 300kw (i dont know much about turbos at all im a noob sorry) its going to be a street/ track drift car. is there any other turbo you would suggest for my setup?

How much money do you want to spend?  Hypergear stuff can give you same same for less $$.  Borg Warner can give you more power or better response for somewhat more $$.

Hypergear stuff would be fantastic just they don't have any twin scroll options.

Once you go twin scroll you don't go back lol.

However if your budget is somewhat flexible I would consider an EFR7163 in TS with the internal gate. Would be a good match for a SR20.
