Title: VQ25DE/HR
Post by: Libra on August 04, 2020, 10:28:09 AM
Hello, I seek your advise on putting VQ25DE/HR engine in Calibra. Frankly I want to know if anyone has done it, how hard/costly it was, what are the common issues before and after swap I assume it is a much lighter engine then x20xev, how does it impact car balance?
How much boost can VQ engine take without modding block and pistons? Can you pair VQ with gm gearboxes? More specifically FWD F18? Please help, any info regarding this subject is welcomed and appreciated.
P.S. Is it worth searching HR version or DET, or is DE just fine?
