30/26 From Rwd To 4Wd

Yeh it does use the standard pick up. Cheers

[GTRPSI]

ill get pics tonight.

and start a spacer thread.

keep an eye out.

Thanks Luke will keep an eye out for it.

Doesn't running a spacer throw your suspension geometry out?

Doesn't running a spacer throw your suspension geometry out?

yes.

but I havnt felt any negative results from it yet.

[luke gtr]

oh, so does lowering your car...

[Shoota_77]

The lower you go in theory the worse the geometry will be compounded further by spacing the k frame down. Presumably there is a point it would get to where it starts to cause a problem (vibrations, grabbing, noise, etc). Shows how capable a cv joint can be for there to be no obvious issues.

[luke gtr]

ive raised the car about 1.5 inches since purchase 6 yrs ago.

the dropped subframe 30mm.

so pretty much back to where it started.

[luke gtr]

oh, I am getting vibrations.

but thats from tyres.

[TwinTurboCelica]

I was thinking more like issues with bump steer etc.

But good to hear it has no noticeable effects.

could also be because im a shit driver and dont notice?

yeah, ill go with that

[GTRPSI]

Luke, did you use 10mm spacers for the front subframe or did you go more?

Reason i ask is because you say you dropped the subframe 30mm......

If so did you just use longer bolts through the front chassis?

[luke gtr]

I went 30mm.

had spacers turned up.

Then used shank style nuts made to suit.

were done by an engineer who builds race/rally cars, and was very happy.

[GTRPSI]

Thanks for sharing Luke, im going to look at mine next weekend to see how im going to approach what you did.

Didnt want to start a new thread but can we hear more about people running the gearbox bolts out ?
Was it okay , or was it worth getting the holes welded and retapped?
Hate the look of it aye, havent got a full tune just yet but yeah.. doesnt look the best and im a lil worried about the torque through it.

[Shoota_77]

It's not ideal but not the end of the world. There's minimal actual "twist" between the engine and gearbox. All of the force runs straight though the shafts, not the box. The only force is created from the friction of the input and output bearings so basically nothing.

There's a huge number of cars that just have a cover plate over the lower half of the gearbox so don't have any bolts holding them to the sump.

[KiwiRS4T]

My RB30/25 is missing a couple of bolts. I guess if I were to get a Spool 3.4L kit and 1000hp I would drill and tap new bolt holes but I don't see a problem as yet

[sultanaz]

alright beauty. Im only gna have about 600hp anyway, but i still look at the design as being poor. and should probably get it redrilled and taped.

Even for getting the car engineered and such .
