Rb25 Neo Touches Strut Brace On R32 While Reving

I took me over a week to realise that it was the engine touching the strut brace while it was revving that was causing the vibration in my car. I put a silicon piece there but it feel off. My question is...will it put pressure on the engine mounts or anywhere else that can cause damage? . Should i be worried?

I wouldn't be overly worried about damaging engine/strut mounts, as RB's have very little radial rotation under load to begin with, and those silicone hoses would have plenty of 'give' in them. I am pretty OCD about things like this though, so if it were me I'd look at getting a different strut brace, or having the one you have there C-channeled or relieved by an engineer to give clearance between it and the intake pipe.

EDIT: It occured to me that could be a GT-R strut brace (which sits lower than the Gts-t brace). If so, just get a brace intended for that car.

What engine sub frame are you using? R32 sub frames make the engine sit higher than r33 etc as far as I'm aware. Mate had a similar issue in a 180. Switched sub frames to a 33 I believe, problem solved

i wouldnt have a clue but id rather just take the brace off then change the subframe

it is a r32 gtr strut brace, the gts-t one sits lower. Also, telling me to get the one intended for the car doesnt help, since the chassis and the engine are different. Its is a factory gtst.

I'm pretty sure that there are thinner engine mounts of another model. From memory an r31 but you'd have to find out if that's correct and if they are a straight fit.

No, R32 GT-R strut braces generally sit lower than Gts-t strut braces due to the RB26 having a forward facing plenum. If your car is a factory Gts-t, either get the lower subframe like 32vspec said or get a Gts-t strut brace.

so wait a minute, if it's not a gtr or gtst brace, then what is it?

      In B4 "Not a Skyline"...

      You're not the first person that's said that about this car lol. A Touring wagon GT in Spark yellow mica would be the dog's danglies 😆 I will keep an eye out for a future purchase for sure. The seats are almost like the OEM Recaros... electric adjustment for fore/aft and tilt movements except reclining.

      Yes!! I love these! It's a shame its not the wagon though!   Thank everything that's holy that it doesn't have the interior of the Aussie delivered ones. Those seats are so much nicer.

      In B4 "Not a Skyline"...

      By Rezz · Posted

      2001 BE5D Subaru Legacy B4 RSK (3rd gen) EJ208 (pink injector) Twin Turbo 280PS 5-speed manual Full time 4WD "RSK" grade which means all of the above LQC option which means stock rear spoiler  I got it primarily to export to someone outside Japan who was interested. These BE5 Legacy B4 RSKs are going through a bit of a resurgence right know in Japan as they are one of the few cars from the "turbo, manual, RWD/4WD, 280hp gentleman's agreement era" cars that don't require stupid money to purchase. Which for some people might be a good opportunity to get as a base for restoration. If I can't find anyone to purchase it I will certainly be doing that myself over the long term. Why? Because it's properly fast in stock form, handles well enough for a GT sedan, there's still enough aftermarket and (if you can wait a while) genuine part support to make it a restoration candidate (<-- that will only get worse over time so it's a case of do it now or choose get a BL5 4th Gen). Mechanically it's fine, has only 89,200kms on the odometer. The problem with this car is that the body and exterior trims are weathered from at least the last 10 years being parked outdoors. I'm the 3rd owner, the first owner was the one that had it for 14 years and barely drove it, had a low-speed front impact (which didn't damage anything behind the radiator support) and got it fixed and sold it. The 2nd owner put most of the kms on it and parked it outside for the last 10 years, hence the door rubbers have seen better days but if you overlook those cosmetic details, it presents pretty nicely. There is some minor rust on the LH rear wheel arch which I'll have looked at too at some stage.  Also as you'd expect from a car this age, the clear top coat is gone, leaving a satin finish on the roof.  Mechanically it's fine (as you would expect from a car with less than 100K kms) but the steering does feel slightly vague around the centre position at higher speeds. So first on the list is to get the steering rack bushes looked at. There's also the Lock button on the remote which doesn't work, but the Open button does.... it means that the anti-theft system thinks it's always open? It seems like if you open the car and don't start the engine within 3 mins or so the anti-theft kicks in again without any beeps or signals. So if you got to start it after that, it won't. You have to push the open button again. That's how I understand it anyway. Just a small irritation but not a big problem to sort out. There's only one mod, the Wangan SPL muffler. Just a tad louder than stock. It's a really good mod for those who don't want to wake the neighbours but still want to hear a more prominent unequal length header EJ20 sound. Anyway I hope to get all those things done eventually, that is unless someone wanted to import it to their country from Japan (where I live). I'm open for negotiations as I really would like a Skyline... but this will definitely suffice in the meantime 🙂 *Disclaimer: This is how I picked it up from the dealer, minus the stuff on the back seat. I haven't cleaned the engine bay or done a thorough exterior clean, aside from spray painting the wipers.

      Wow, even with the Audi logo centre caps. I love OEM wheel mismatches.
