2GR V6 conversion parts

we are working on a 2GR V6 conversion into a SW20.

A guy in the US has made some nice exhaust headers and engine mounting brackets. anyone interested in these parts so we can buy a few sets to get the freight price per kit down to something sensible????

check out this link if interested

Bugger, Any ideas on conversion costs (ie just getting it in and working, not supply of after market ECU or any engine work).

how much does the mount cost?
plus whats the chance of you boys being able to make me a loom ready to plug in and make work if i was to carry on with the conversion myself?
2010/12/31 00:20:16

what mount?

call me about harness. can do i guess, but wont be able to test without your car

And the mount I'm chasing is the drivers side engine mount bracket for the 2grfe
Wich is pretty much the only mount that needs to be changed as the other three engine mounts are on the gear box

in regards to the kits
im interested in the kit that includes the mounts and the other little bits and pieces along with the headers
whats the group buy looking at?
and in how long till the group buy goes ahead?
2011/02/01 20:20:55
Road and Track
what "group buy"???. you are the only one to ask for a kit .see threads above
i can make more of the clutch slave cylinders , wiring stuff etc etc, but it would not make economic sense to make the headers & mouning brackets here unless I get a lot more interest than just you.
I thought I would be swamped with enquiries once the word got around as to how good this conversion is, but it seems not to be the case.

V6MR2 just get in touch directly with Gouky from TwoBrutal.co.uk if you haven't been on there already. He's the guy that makes and sells the mounts and exhaust manifolds to fit the MR2.

There is a heap of info on the swap there as well.
2011/01/06 16:40:15
v6mr2
I'm still chasing down a well priced half cut, and are you able to discuss pricing for the clutch slave and the wiring?
And I was talking about the wiring to my uncle, and we have a question about the immobilizer system, if it uses it's own ecu and wiring loom Wich then connects tomthe ecu, then wouldn't that mean that the immobilizer ecu just sends a current or a signal to the ecu letting it no that everything ok? If so, wouldn't it be easier the manipulate this signal or current to the ecu and not worry about all the Imobilizer crap?

And Justin i guess I'll have too, unless there is a way I can get my hands on actual dimensions and make my own?

Manifolds would be simple enough but mount adaptor would be a hell of a lot of r&d. The mount gouky sells is a quality bit of gear especially for the price. BTW he is in the states so should be even better priced now than when i got mine

we decided it was cheaper to buy the mount adapators than make them when we did Matts car. i think the same will still apply. it would be a huge amount of effort. HOWEVER, the mounts are far from a perfect fit, and we had to re-machine/modify what he sold us, plus the origtinal 3SGTE cam end rubber mount. If we had a few buyers, we would tool up to make them locally.If you deiced to buy his adaptors, I'll modify your cam end mount for $75.

modified clutch bracket $150 exchange

wiring. $2000. send me your 3SGTE harness + Aurion harness I'll adapt it all and make send back loom + new wiring to throttle pedal.

security computer etc. no , you cant just by-pass it with a simple device/bridge/signal. i could probably design a solution, but the time effort is not worth bothering at this stage. you need the Aurion transponder key, transmitter coil that surrounds it, security computer. thats part of my wiring job.

I can supply a complete aurion engine + engine electrics + security systems stuff for $3800

2011/01/08 09:05:30
v6mr2
3800 and it will be ready for me to put in? If so then that sounds feasible.

Would it be feasable to supercharge that engine in the 2 or is that a ridiculous concept?
2011/01/09 00:51:39
v6mr2
I think they do low thirteens Down the quarter with the na 2gr fe
Now looking at the aurion Wich is where there from, I think there's half a second difference between the standard aurion and the Trd (supercharged) version, I don't see why that wouldn't apply to these two engines compared to each other in an mr2?
Mid to high twelves maybe?

v6mr2- Toyotas immobilizer equipped ECUs work like this

the transponder ecu needs to recognise the ignition key put into the ignition barrel
by detecting the chip(or whatever they call it) in the head of the key
that then tells the theft deterrent ecu to send a (rolling) code
to the engine ECU
which then sends back a different rolling code that the theft deterrent ECU will recognise
if either ECU does not get a code recieve/response the engine ECU turns off
and logs a failure
after several failed start attempts the ECU locks itself OFF.

this is how it worked in Toyotas from around 1995 onwards
I imagine there may well be even harder to defeat systems on the latest gen stuff.
although even the older stuff doesn't seem to have been cracked
to elliminate the immobilizer gear.

So without the complete system
you basically have an empty box that holds all the ECU plugs in an orderly fashion.

Surely thats even more of a reason to go aftermarket ECU.

Sounds like alot less hassles than trying to get the stock ecu/immob setup working and gives more scope for mods and tuning.

no, the aurion engine/loom/electrics price was for a standard one out of a wreck we have. all the other work to make it fit into a MR2 is extra as per my prices. if you are serious about this conversion from us, phone me during work hours please

i suspect you will never get it mod plated/registered with a non standard ECU unless you want to pay the $8000 or so for the ADR emission compliance tests.

a supercharger will not fit easily. as a MINIMUM it will need radical changes to the engine lid & strut braces . the belt drive system will be a struggle to fit as the stock V6 only just fits in this area. I got a genuine TRD Aurion supercharger manifold to check it out

Wouldn't be 'too' radical for the engine lid, struts most likely.

Wallet? lotto territory...

as long as you get all the parts(not forgetting the key) from the donor vehicle, its fine.

to get Transit Authority approved/registered
is much simpler with a standard set up.

aftermarket ECU requires getting full emissions testing done as well
which can get expensive($/hr) trying to meet current level requirements.
Last I spoke to a guy who offers emissions testing/passing
he explained that it usually ends up costing between $800-1000
but includes/involves a lot more(parts) than just tuning an ECU
in that figure, to get to the result.
Then you go to the Transit test facility(which may be 100's of km away) and they test it and take more money.)

example of lack of facilities
NSW has 2 Transit Authority test stations
Botany and Penrith,here's where they are positioned in the state(blue dots)

not too bad if you happen to live near one.

*edit*
Note that by emissions testing/passing I did not mean that he is authorised to pass the car
but gets it to a passing level
where it will pass the test when taken to the Transit facility.
And the price(2yrs back) was his price and is not including the Transit Authority costs.

all the rules have changed in NSW as of mid December. suggest you talk to NSW registered engineer before making any assumptions. make sure the enginner is registered under the new scheme (I'm told they all have to re-apply),.

Hay Road & Track,

I live in SA but am interested in the V6 conversion
But I have a few questions

1st Is the engineering certification nationally accredited?
2nd what would be a around about cost to supply /fit ballpark (IE: I drive a MR2 up to you. Drop by few month latter and drive out [:x)])
3rd what time frame would it take roughly
4th would it have fitted /is there room for the AC compressor?
5th what base is better gen 1,2,3 / N/A or turbo is it not really impotent

Cheers
Iain

no such thing. although it is state by state, there are a lot of commonalities. needs more investigation to make sure you wont have a problem


2nd what would be a around about cost to supply /fit ballpark (IE: I drive a MR2 up to you. Drop by few month latter and drive out [:x)])

too many variables, but assuming i get a post 94 turbo car, then around $10k (exchange, ie we keep the old engine that comes out)

3rd what time frame would it take roughly

1 month

4th would it have fitted /is there room for the AC compressor?

a/c fitted in above

5th what base is better gen 1,2,3 / N/A or turbo is it not really impotent

see point 2. if you want to deliver something else, then phone me
2011/01/31 16:56:11
Just1n_Mc
So if we send you our +94 turbo you can convert it for $10k driveaway? Does that include exhaust manifolds and everything?

Thats no to bad considering you can re-sell your turbo gen 3 motor, loom and accessories for around $2-3k depending on mods.
2011/01/31 19:09:15
Road and Track
sorry, price assumes we keep the old engine. i have amended my reply..
if someone really wanted to keep their old stuff, we would negotiate a price
2011/01/02 09:01:31
Just1n_Mc
Oh ok, maybe not so cheap then.
2011/01/02 22:09:04
Road and Track
no, its not 'cheap", but nothing is. for example, it is less than the cost of building a really good 3SGTE if you allow for uprated turbo, good internals etc, and this is a much much better end result.
this conversion is not for everyone, and few people will spend big $ in 1 lump on a MR2.
Every day, i see cars that have had twice this spent on them over a few years, and they are still not good, in fact, some are complete lemons that should be off the road.
