Hi guys, I just came across a complete front subframe assembly for an r34, the title of the ad just says r34 so I’m presuming it’s a coupe. I have an R33 at home and was wondering if the r34 front subframe assembly will bolt straight into the r33. Im looking to do this with relatively little modification of its needed, also does anyone know if it will throw off the geometry of the car or if it’s okay to be doing this. Thank you very much if you’s can help guys :).

Forgot a detail

They are very similar, but I don't think this has been done before/information is readily available.

I know there are *SOME* differences in arms between a 33 and a 34 in the front. Ostensibly they are different for 'some reason' but I don't know if the front subframe is the reason for it. I have bent knuckles and front arms before and found out that the 34 ones have curves in them where the 33 ones are straight. But you also have things like 33 coils fitting in 34's and vice versa (at the front only) and sway bars (I think)

34 coupe and sedan are the same at the front, but as the front subframes generally dont get uh, broken? It's not something that generally gets swapped between cars..

Oh okay, thank you for the information. It’s just because I’m looking to get my r33 on some wheels and came across an r34 front subframe complete, for a reasonable price and was just seeing if they were compatible with the R33 haha.

 

thank you though :)

    • Hope you aren't too sore after that one, might take a day or 2 to notice yet and I guess it is a loooooong drive home. On the bright side, tube frame front end is a thing at superlap, right?

    • The chart of front pressure to rear pressure (with one being on the x axis and the other being on the y axis) is not a straight line on a typical proportioning valve. At lower pressures there is a straight line with one slope, and at higher pressures that changes to a lower slope. That creates a bend in the line at that pressure, called the knee point. If you do not change the proportionng as the pressure gets higher, you will suffer excessive pressure (at one end of the car or the other, depending on which way you look at the proportioning action) and then get lockups at that end. The HFM BM57, from my memory of previous discussions, is based on the BM57 from a different car (to a Skyline), with a different requirement for the location of the knee point and the distribution of pressure front to rear, and so is not a good choice for an upgrade on a Skyline. Here's a couple of links to some old posts, one from here, one from elsewhere. A lot of it pertains to adjustable prop valves, but the idea is the same. There are plenty of discussions on here about this issue from al the many years of people wanting a cheap/accessible option. https://grassrootsmotorsports.com/forum/grm/learn-me-brake-proportioning-valves/236880/page1/ https://grassrootsmotorsports.com/forum/grm/learn-me-brake-proportioning-valves/236880/page1/  
    • Yeah dunno why johhny posted that here with no context, just post on FB/insta bro where he put it up?  Laine had an off at T4 during Thurs prac, he's ok, car is less than perfect, they are done for the weekend, he can fill in the rest. Bando also binned it like 100m up the road.   
    • I feel there must have been a FB/insta post and the weekend did not start well at all I hope everyone is all okay
