R33 Rb30 Conversion

[conan7772]

GT42/HKS T51r fits fine

<{POST_SNAPBACK}>

Can you get a front strut brace across that ?

I guess everyone with the RB30 is losing it.

[Bl4cK32]

why is everyone strung up on the damn strut brace.

Make new ends to offset the bar across the engine to clear the tb.

If your building the engine, you have to cut and weld the engine mounts, so whats hard about making new strut ends at the same time??

[Craved]

possible issue with making the strut brace higher is that i know my strut brace had rubbing marks on it from the std bonnet.. so i know i wouldn't be able to make the strut brace higher ..

saying that i am hoping i wont have an issue with the plazmaman front facing plenum.

[Bl4cK32]

you dont make it sit higher, you move it forward not up

oh .. right :lol:

yeah makes sense now hahaha

[BADR33]

yeah my rb30s now fitted. i didnt need to mod the engine mounts. just a slight hammer on one of the under bonnet supports. looks damn sexy.

should have it running on thursday

now only if it would stop raining so i could go outside and finishd changeing the fuel pump

yeh but how rigid is it going to be ?

I haven't seen any pics either.

See pic below, can't move it forward with the RB25DET head, have to go right back against the firewall.

Useless...

Same as the bar was before, or make it better.

I havent posted pics, but whats so hard to picture about it??

Your simply offsetting a bar forward, not making great structural changes

[Cubes]

This is what came out of the rb20det gearbox + lots and lots of large chunks of teeth, be buggered fishing them out of that stinky oil.

Drain Plug

The back of the tooth where it broke

The mesh side of the tooth, looks as if the engaging gear was really digging in and not meshing with the whole tooth. :S

The new box is very very quiet.. Feels quite strange, like a new car.

[GTRgeoff]

Thats a fatigue failure as you can see from the close curved lines across the broken face and the rough area to the other side of the break.

Starts somewhere about where I've marked as best as I can discern from the photos.

Just couldn't handle no more Cap'n

[Cubes]

This pic illustrates the close curved lines a little better.

Sorry Geoff.. I don't follow the Cap'n...

Do you mean repeated high load that attempts to and may very well slightly bend the teeth every time?

A little like breaking a coat hanger by bending it repeatedly.

So definitely rb30 related?

Can't go forward.

There's nothing between the induction pipe and the bonnet.

Running a bar behind the BOV is too bigger an offset.

It will flex under load i.e USELESS.

What head do you have ?

Gees you got that in quick !

What did you pay for it ?

[Cubes]

The new 20t box with warranty (lol) was $500.

A pitty I wasn't prepared for the big bang.

I'll track down a well priced rb25t box get a tail shaft sorted and drop that in, eventually. Hopefully before this 20t box blows.

Yep strut brace fits fine except it hits the hks heat sheild

ive got the 25de head, and you can move it forward.

edit/ im not going to argue about it, but in a 32 it will fit

I've only seen one unknown strut brace that positions the bar in front of the throttle body/cross over pipe.

[Waldo]

hey guys...my rb20 just blew up..and im considering doing this conversion as i have heard its a great upgrade....just one question though...i have a rb20det power fc...but if i do this conversion i want to run the rb26 head...will my power fc work with this head (i dont mind if i have to rewire a few things) i already have modded the wiring loom for stock gtr injectors. any help would be good

cheers

[Cubes]

It will work fine providing you stick with a single afm.

The only sensor that 'may' not be used is the intake air temp sensor, I am not 100% sure what pin or if it indeed can be used with the rb20det pfc.

SK has said it has or can be done? Not completely sure.
