Whelp, as some of you may know, my pride and joy took a tumble. Rolled her about a month ago so it's time for bigger and better things. I've had a B13 SE-R for a couple years now sitting in my yard waiting for a drivetrain. I've had plans to do a 600whp QR build and swap it in but have never had the money to buy a donor car for all the parts. Now it seems I have an entire drivetrain in my garage so I'm getting underway! The plan is to install rods/pistons this winter and run stock sleeves and stock cams for now. I'll only be pushing about 450-500whp for the time being cuz I don't wanna prolong the process by having to pay for and wait for sleeving.
I already have the engine and trans out of the b15 as well as the subframe. Within the next week or two I'll start on fitting the subframe. I'm extremely thankful 2JR decided to do this swap and confirm that it's not all that in-depth cuz I've had this plan since before that was even done just didn't quite know how I was gonna go about it.

Here's progress pics so far.

Fuck California...
Does that answer your question? lol
Can't wait to be updating this with photos of the dogbox setup! But for now, it's just an 'anxious' post.
Car is currently hibernating (in a much warmer climate) awaiting my arrival for some more TLC in the hunt for 8's this season!

Let’s hope I go 9s and you go 8s but I doubt I’m going 9s lol
Hell yeah been looking forward to it.
Hello good to see this build 700whp no joke. However I myself would also like to go this route but I would like to use the newer qr25de 2009+ engines. Is there a difference between the Awd qr25de( Rogue, xtrail) and fwd qr25de( Sentra etc) because I'm planning to have the qr25de in awd format in my car it's a awd b13 from factory. I saw some other post of qr25de b13 but it's a long time ago. I know for the sr20's the awd blocks a thinner than the fwd that's for clearance on the transfer box. But I'm new to the qr25de and it's not that popular so I don't have all the information I need to go ahead. If the engines are exactly the same fwd or awd then I don't have a problem. Just have to focus on mounts.
