I have a RB25 sitting in my garage and have still not been able to make up my mind to swap it in my G or find a ER34 chassis to swap it into and later turbo the G. I know Inline engines create more torque than V engines and Iron blocks are harder than aluminum but at the same time heavier. I was wondering if anyone can give me some more insight to help make this decision easier. Many Thanks

 

This is a twin turbo vq about the same whp for comparison

Notice the trq.. about 400 with 538whp.

 

PSI is above 20 on rb.. while its much lower on the vq.

 

There's a guy on this forum called G37Sam who's done an RB swap in a G37 and posted all about it. Take a look.

 

Dyno says 1998 G37 lol

 

You've been posting about this for almost a year now man. Given your hesitation, I'm not sure you're going to do it haha

In all seriousness though, if you have an MT G and someone who knows his way around UpRev and our cars, a twin turbo kit is the easier way to go. An RB Swap is a full time job, it's been almost a year now and my car is still not where I want it to be.

 

Depends what you are going for man. If you want rediculous HP then go for the RB and open your wallet. If you want a very fast car with useable HP then stick with the VQ and still open your wallet but just not as far lol!
