Brumby STi Conversion Help

[Guest]

Does anyone know how hard this sort of conversion would be e.g running gear, motor, ive always wanted to do it but just dont know how to go about doing it

Any tips??

exactly bro, ever since i watched this on high octane ive wanted one, but apparently its a real mission to do

Find a good engineer who has chopped chassis before as this is what you will need to do to fit an sti motor in, nand someone who knows how to wire it up... all the rest is reasonably straight forward ,

Thanks man, are there many sti brumbys in NZ?

[dubbedup]

id say there is prolly 1 or 2, i doubt many people can be bothered with all certs that need done.

[sickmatesick]

there was a green one down here on trademe a few years ago that had a gt legacy conversion, looked like fun pretty sure it sold for around 5 grand

What kinda certs would i need to get

Umm, Low Volume Cert... :

[dubbedup]

And the one for the chassis being cut are shut, i cant remember the exact name but it is not covered by low volume cert, at least it wasn't 5 or so years ago.

As with most things,it can be done but it Will cost,firstly u need to get a complete STi as u will need the engine,gearbox and complete running gear as nothing on the brumby will be suitable,you will also need to find a good brumby chassis (this would be the biggest hurdle as they are hard to find and "good" ones cost between 2 and 5 k )

Now that you have both cars you will need to take all of the running gear out of both.

Now you need to figure out what needs to be cut out of the brumby to get the engine to fit as the brumby's chassis rails are designed for a pushrod motor and not a double ohc setup,the single ohc engines do fit son you could put these heads onto STi block to get passed cutting the chassis rails.

Next you will have to make subframes or adapt the wrx ones to get the wrx gearbox,suspension and brakes to fit,also probably need the wrx dash and pedal box and clutch and brake master cylinders,

Ok almost finished wire the engine and chassis to run the wrx ecu and lights and such(I would just install the wrx loom)....

Now comes the hard part getting it certified,as long as you are running the complete wrx running gear and all modifications to chassis and the subframes are done by an engineer and u have the documentation to prove it then you shouldn't have an issue..

Why do I know all this i have brumby in my shed and thought the same thing until I figured out it would cost about 10 k and that is with me doing all the welding and cutting as I am a certified welder

Decided to supercharge it .....

Thats what stopped me with my one. I was going to fit a 3.3 and 5 speed sti box and drive train in to my old brumby ( same one DRFVDR has now )

It was just going to cost so much. So much work was needed. I also lacked the use of the welder which didnt help either.

I desided to sell and invest that money into my other project.

[dubbedup]

If you can do the work yourself and are prepared to put some decent hours into it im sure you could build a non sti Ej20t for under 10g, I know i could and im no welder

[DacerX]

same goes for my project it all comes down to money, time and skill

[DRFVDR]

Damn u buggers now i may have plans for the brumby and it involves a EG33 and a FWD gearbox

[Koom]

Are you going to put the engine in the back?

[DRFVDR]

thinking on it will have to take some measurements to see if the engine will fit between the rear axle and the rear of cab mmmmmm mid mounted eg33 brumby sorta ruins it load carrying capabilitys

DOOO IIIET!

[DRFVDR]

Damn it can any one measure how long it is from where the axle comes out of the gear box to the radiator on a legacy ( I know a eg33 fits in there )

I have 700 mm

I remember seeing a pic of a EJ20? (maybe EA82) and FWD Gbox on the back of the brat on USMB?

They had lined up the CV shafts up to where the center of the rear wheels.

It looked like that would just fit between the rear wheels and the back of the cab.

[CUDDAS]

I make it 630mm from the center of axel stub on the trans to the back of the radiator, not incl the fan just the factory radiator itself

here's a nice looking brumby to start with

nice brumby I already have one

mmm so it will fit damn it now i have to have alook to see if it doable without cutting to much chassis out

[DRFVDR]

mmmmm may even do an ez30r about the same price as a eg33

now to find a FWD auto ( for ease of linkage )

[Trent]

i want to drop a eg33 in my gc8 but i want to forge it but i cant find anyone to buy the parts off .you got any ideas?

[DRFVDR]

AFAIK there is no commercially available forged internals for the EG33 my step son has been doing heaps of investigating as he is wanting to run a turboed eg33 in his river race boat
