made 250.1 on 17psi but DOPPED off to 14-15psi due to wastegate flapping open.

need a stiffer actuator spring and should make 280 on 17-18psi.

      Its also very clearly made to take business away from https://theskylineshed.com/ which is legitimate and even has a physical address.

      The 'About Us' got me ..  I added something to the cart and clicked 'check out' and none of the payment options in the footer (ie those with buyer protection) were available. Stay the hell away from this one.

      No. Not true for any non-GTR R32. I think even the GTS4 has the GTSt knuckles with eye type lower shock mounts (as opposed to GTR fork lower shock mounts). The only R chassis in which something like the quote claim is true is the R34, on which the turbos have the fork type and the NAs have the eye type. **Edit: Actually I reserve the right to be wrong about the above statement. It might also be true on R33s. My memory on those shitboxen has faded too much.

      It's a scam. It has all the telltale signs: - The "business" doesn't have a physical address or really any kind of information listed - It's using a generic online store website template - The prices are ridiculously reduced. To good to be true cheap - Everything is in stock and can be ordered in any possible combination   I've seen a few of these for other products as well. Things like sunglasses for example. I'd say stay away from it! And maybe reach out to the real theskylineshed and let them know this exists. I doubt there is much they can do about it, but still.   I don't know if they would actually take your money if you ordered something. Or whether it is just for collecting credit card details to scam otherwise. I'm not game or stupid enough to try it.
