Good Morning All...

I have a couple of Engine mod Questions that I'm hoping you guys can help me out with..

I'm thinking of installing a V6 Twin Turbo 2ltr into my Type3 IRS based Kitcar. This car has been Rego'ed in QLD with a EA71 Subura engine once before, but currently is not.

Q1- What kind of issue will I face trying to get this car through QLD Rego requirements?

I'm already going to install a "SHERMAN" front & rear disc brake kit.

Q2- The V6 is going to need to be moved back around 75mm (3inch). This is going to move the position of the drive shafts on the 091 gearbox. Will this effect the rear IRS?

Q3- With the gearbox moved back I'm guessing I'm going to need longer drive shafts. Who is the best person in Brisbane (Or anywhere) to get modified high performance drive shafts off?

I still maybe able to move the radiator towards the rear of the car to allow the Kombie box to sit in the same position as the STD box that is in it now but it will be extremely tight with no real room between the rear body shell & Radiator. Which I think maybe an issue in itself..

I really do want to put this engine into the car & I know the Subura would be alot easier but how cool would a V6 be.. ?

Thanks for any help you maybe able to offer..

Cheers

Q1 - you need to start talking to an approval engineering before you start working on your project, and do what ever they want you to do.

Are you talking about the nissan VG20-ET engine, or the 6A12G twin turbo?

the VG20 is quite old and makes less power than my NA V6. The 6A12G is a good motor but I am pretty sure it is cast iron block and weighs a crap-load.

Q2 - I definitely would NOT go moving it back if you want the car to go around corners. Moving it back and having a heavy engine will really screw up the handling.

What kit car is it in anyway?

Custom Offroad should be able to help out with the axles.

see WEs was there fast !

Wes is correct that the motor is less power full than his .There is allso less parts about .

The Subaru parts can be found all over he place & there is many after market bits about .

Dont wast your time with the V6

it all depends which v6 he is talking about neil.

as stated the 6a12 twin turbo has bundles of torque .etc and would eliminate a subie in the right vehicle.

Subarus are good..BUT THEY ARENT THE BE ALL AND END ALL.

i say, get exact measuremetns of engine .etc or even the model engine that it is and post it up and im sure you would get a host of helpful responses.

if you want a lightweight powerful engine....13bturbo...no competition.

if you want an unfortunately more 'common' conversion go the subie (any model)

if you want the cool factor...stick to v6...but maybe single turbo due to cc/weight factor..

talk to a engineer that is approved with the road authorities in your state before you buy or start anything.adrs are changing in each state .

Keeping in mind you have a Seagull adapter plate & fly wheel in stock



Take your own path

what ever is said on here some one allways tells you some thing else any way

I gave up long ago

I have a 13B turbo

6 wrx motors

VG30 T

V8 toyota

SR20 n/a

RS turbo

& a new STI wrx in the drive way

From the above selection of motors out there is amazing .

get what you can that fits the price & get to it

like I said first up, the 6AG12TT is a cast iron block. It is very heavy.

I wouldn't use it because of the weight. I definitely wouldn't use it if you need to move the engine back even further.

Most engineers won't approve it for the above reasons. They shouldn't approve anything that really messes up the weight distribution.

Custom offroad can point you towards a good engineer.

Do you know what model type 3 pan it was, and what the original vehicle weight was for that model?

the subie and the 13Bturbo would work well and you mighten need the orignalecu looks like Motec is emission conpliant.

engine size wise you are fine legally. a 2L turbo V6 or 4cyl are the same size and therefore the same rules.

There is clauses in the rules regarding weight of the engine though.

The swingaxle VW suspension is independant, but it is crap compared to the later 4 joint trailing arm design which is referred to as IRS more commonly.

Here's the extract from the QLD code of practice for light vehicle modification;

this paper gives the EJ20T weight as 147kg.

The only thing is I don't know what accessories that included.

My 2.5L V6 with absolutely everything bolted to it (intake, cast iron headers, exhaust back to the cat, flywheel, AC compressor, etc) weighed 176kg. It is on the heavy side of what you'd want to use, and it is all alloy.

Don't know about the 6A12G. here's an old post where another guy was gunna use that engine;
http://www.aussieveedubbers.com/forums/viewtopic.php?tid=52662

type in engine weights into google you,ll get a lot of aircraft sites and they list weights on just about every engine even some gearboxes.

all the engine weight lists on the internet are old and only really useful if you want to use an engine from the 70's.

You won't find many hi-po jap engines listed in them.

They also don't tell you what state of completeness the engine was weighed in. My V6 would be very light with all the stuff taken off. The flywheel alone was 10kg.

I phoned Brad @ COR's today & from the chat I had with him it is possible.

Is the 6AG12TT a cast Iron block? I have been trying to get hold of the guy who owns the engine today to find out, without any luck.

Anyway from what Brad said if the unit is in the 180 to 200 Kg range it would be hard for it to be past. The only advice he had was to take a set of bath scales along and set them up with a long length of wood. One end on the scales & one end on a block set up the same level as the scales. Place the engine @ the halfway mark & double the recorded weight..

One thing I didn't ask was does this weight include the gearbox, adapter plate, clutch etc etc? I'm guessing not as he was quoting 147Kg as the weight of a Subura donk..

So does anybody know what a gearbox weights? just incase they are connected?

Thanks again guys.... Guess who will not sleep tonight..

I hope to collect it tomorrow if I can get an extra set of hands to help me lift it onto a trailer..

I weighed my engine with a load cell.

I also weighed a 1600/1700 Type 2 VW Bus transaxle which came to 38kg.

If you do move the gearbox forward that will help your weight distribution.

Be careful with the bathroom scales. We tried that with my V6, but couldn't put the weight onto the scales gently enough, and they collapse sideways. They aren't made to weigh engines :P

Well this project has been canned..
After going & looking at the engine the measurements were different to ones quoted & it is just too big..

Looks like I'm back to a EJ20T or TT engine.

Thanks again guys for all the feed back..
