will cost or what type of sr20 det engine should i put in

 

You have the perfect amount of funds. I would go with the u13 bluebird SR20DET. You can find them on www.jgycustoms.com . They are one of the major suppliers of JDM motors. But, when you do get this motor, I would recommend upgrading the turbo to a T28 turbo because the T25 turbo runs out of room to breath up above like 5500.
