Hello.

I have a R34 GTT and because reasons, I need to maintain stock geometry.
However, I can change the geometry.

I have a few questions.

1) Can I get a non HICAS subframe and bolt everything from the GTT subframe into said subframe?
2) What parts of said subframe determine whether the rear shocks can be fork or eyelet type? I do not want to change from current fork type because I would like to keep my coilovers.

My ultimate goal is to convert my current car into having stock rear toe arms I can set with an adjustable whiteline bush for configurable toe.

Answers to inevitable questions: I have a HICAS eliminator kit already. I can not use this.
The diff has to come out because reasons anyway. The tailshaft is removed for reasons anyway as is the exhaust. There's not much in the way of removing the subframe.

I would also like to put every bush known to man into whatever subframe (i.e the R34 non HICAS one) goes back into the car. Is there a kit for this? I don't know the names of every bush that is on every site and this is quite confusing to me. I do have *some* bushes already. Can I re-use these?

I have pineapples, and rear camber adjustment for the current uprights in the GTT.


How much of this can be re-used?

OPTION 2:
Buy HICAS parts and put into GTT subframe.


Surely no one wants option 2.

I searched, oh god I searched but I'd like confirmation before I buy a subframe I can't use, or one that requires me to replace my diff, or axles, or coilovers or buy whiteline bushes I already own. I would much rather put HICAS back in than do that.

Non-HICAS subframe goes in.  You keep your uprights, which means you keep your fork type suspension units.  So far happy happy.

You need the toe control arm outer bush inserts (from the non-HICAS car, or preferably new) to replace the HICAS tie-rod outer balljoints.  Easy enough with the usual brute force and a press.

All bushes are otherwise the same and will swap.

So what you are saying is ultimately with having 2 subframes, I can create my own for joy and happiness and success. That is what I was looking for.

Does anyone do a "Hamburger with the lot" bushing kit? I do plan to provide the subframe + said bushes to a workshop with a press to do this. I noticed awhile back I didn't actually need more alignment settings than what Whiteline (etc) adjustable bushes actually offer.

So new bushes, enough alignment and better NVH and friendly with the legalities, kind of win win for me.

    • No need to drill any holes. There's plenty of access to reach through and behind all of that steel to "push" from behind with a pulling action on the slide hammer. There's all sorts of attachments you can screw on the end of them.
    • Yea the photos aren't the best. When I was pulling the bumper and headlights out there was a bodyshop guy looking on for it, there is a slight bend behind where the passenger headlight is, but we're talking a few MM and there is a little bit of a bend for the reo. That said it's supposedly well within the "Drill a hole in it and pull it out with a slide hammer to be close enough" and be on our way. The other option is to buy a GTR reo for the GTR bumper bits but this is a $2000+ fix for something Mr Hammer can probably do 99% of the job for and everything will/can line up pretty closely-to-good-enough.
    • That's a write off for sure... Part out? 馃槢 I kid. It looks like the rad support has a minor minor bend in it too where the rep support sits near. Could just be the photos (and me not wearing my glasses right now). Worst case is you can buy a new radiator support, have it swapped over, and leave the car in paint jail for 12 to 18 months while you build the motor to handle twin turbos or a Harrop SC...
    • It seems the definition of "Gregging" something might need to be expanded?
    • This is why I suggested that there is really nothing that can safely be done in the engine bay at this budget level. Just the work to reassure yourself that the engine won't instantly crap itself the moment the boost gets turned up will wear out the piggy bank long before the first turbo gets installed. Spend $10k and still not have any extra performance? My tip is a version of our standard advice from 15 years ago about buying a GTR, which is not to buy one unless you can afford to buy two. The new version is not to modify a GTR unless you have all the funds required to do it all at once, properly, and enough to rebuild it after it blows up.
