I have the HTP 3.5" too. I entirely removed/relocated the ECU with a Trackmasters bracket. I had to do it an an angle because I didn't want to pull my wiring harnesses quite so tight and/or modify them. Even with everything completely detached from the side of my battery box, the HTP 3.5" still has rubbed through the P/C'ing at the front-left corner of the battery box. I'm not worried, though. It's just P/C'ing. Also, it's worth mentioning that I have a BNR S3, so your intake may not shift as far over as mine sits with your turbo. I really don't know. Maybe someone else can speak to that:
What type of bracket/mount did you use to secure it? That's also a solid idea... Looks like I have a couple of different options.
Just as an aside, part of the reason I didn't go 51R is because I have a system in my car, so I wanted to retain as large of a battery as possible. It may not apply to you, but I thought I'd mention it.
If you don't mind taking a picture, that would be great!
I also have the stock system and I only have a 2 LED attachments.
The HTP 3.5" is known to be a tighter fit right at that corner. I'm not sure if that's in comparison to the silicone and/or metal 3.5" JBRs.
I was not aware of this although the post by @Quigs above shows that the HTP fits with the stock battery box
That's a 3" though
LOL. Happens to the best of us. In all honesty, an HTP 3" is enough to handle 400whp and then some. My 3.5" is overkill. I just wanted to future-proof if I ever wanted to easily handle 500whp or more. Pretty sure 4" isn't needed until 600+whp, IIRC.
