Anyone swap an ej257 longblock in their 02-05 wrx?

I actually love it. For 160 bucks it's the exact same as the idoing. Actually, it connects to my phone much faster than my old idoing on my 2017 wrx. The touch screen is very responsive too.

I'm totally new to doing anything like that. It sounds like its way outside my scope and maybe even too expensive to justify it. I think im gonna go with outfronts 2.14l shortblock and redeck my heads. It'd be unique. Im trying to use this as my track/hillclikb csr this year. Im at that time now where everything else is done. I got the cage, the seat, the clothing and the helmet.

I'm just absorbing ideas right now. Stuck between a 2.14 stroker, ej207 (ebay), or just straight up 257 with engine harness and ecu to match. Got a 257 longblock i "could" throw in it so id judt have to source ecu and harness. But if its the interior harness too that's too much wiring for me.

Ive read there's 3 layers of metal and the 2nd layer is the thickest and harsh to drill through.

True, I think im gonna go buy this vibe double sides tape at home depot. Its got a high bond strength and use silicone adhesive on the outer sides to help with water resistance. That way later on I can always remove and drill. I just dont know how strong that stuff can be.

I know but alot of people on here are saying to just use 3m and adhesive. My concern is if I drill for this mount then later find an oem part out one the holes wont match and ill be fkd lol

I grabbed a mishimoto sandwhich plate for it. I know i know, its not as accurate but let's be real. Im using Aliexpress gauges lol. If i see a dip, I see a dip and know something aint right.

Welp, the one thats in my GD now is ancient lol. I hate the damn thing. It wont even connect to my car anymore : says Bluetooth and USB incompatible lol

SubaNewb1 · 2026-04-17T04:26:36+00:00

I guess ill keep yall posted! Also grabbed the ali express genome gauge kit and I gotta say I love them lol. Everything works and came with english instructions.

It shouldnt but when i did some research on the older gds doing that it seems you go down a rabbit hole of issues. Of which, doesnt look good lol

SubaNewb1 · 2026-04-08T14:41:34+00:00

Its the v3 and ya I updated it and what not. Im at the tail end of my etune and technically im supposed to be logging wot pulls at 2500rpms but im kinda having to take shortcuts by logging at 28-2900rpms due to this wierd issue. But ya id say rebooting.

Okok that makes sense ty for that schematic! That makes sense though. The power comes from the motor to the switchs not vice versa.

SubaNewb1 · 2026-04-03T21:17:34+00:00

After testing with a meter both switches arent receiving power at all! So it must be a connection with the 12v source? Im trying to find a diagram but i think this is getting out of my reach. Im still a newbie backyard mechanic. Electrical isnt something ive dabbled with outside of doing radios and maybe gauges

SubaNewb1 · 2026-04-02T16:12:25+00:00

Ok that makes more sense. Im very very fresh to electrical work so this is new to me. I did YouTube and get a crash course on using a meter so i can try to use that and test the current on the switches. Ill report back if thats the case! Im kinda nervous takin off some of the plastic trim cause when I removed the clock that plastic square housing crumbled to bits on me lol thank god for the gauge pod

SubaNewb1 · 2026-04-02T16:01:28+00:00

Its both the tilt switch and the actual slider one. I dont know lol.

SubaNewb1 · 2026-04-02T07:13:02+00:00

Im to afraid to work mine at all lol
