Hey all I am after some advice if possible.

Has anyone done an STI Conversion on a Bug V7 WRX to STI.

I have a wagon and am contemplating doing a full conversion.

I want to do the Brembo / 6 speed conversion anyway so might as well go the whole hog and do the engine too. My question is: Do I have to change over all the wiring loom and ECU etc in order to have the car mapped once the conversion is done?

Has anyone done this before?

Thanks in advance.

 

mate as easy as it sounds those costs do and will add up and you could no doubt be spending more than it would cost you to sell and rebuy an STI

the gearbox alone will set you back 1500 and the brakes 600 plus the wheels if you have normal WRX ones on

 

Cheers fella, I have a fully working STI as a donar car. I was going to just keep the sti but I love the wagon and decided an STI wagon is something a little rarer.

So i have all the parts to do the work, im just wodering if there is anything I should be aware of before doing it.

 

One of the resons for asking is my wagon is already mapped and I wasnt sure if I could use my WRX ecu as its licenced and mappable or would i need the STI one in place dure the AVCS heads etc?

 

ah bloody hell your all set then

im sure someone that knows the insides of both cars will be along to help soon, but i guess if you have a complete sti your good to go whatever you need

 

Why dont you give your mapper a call or someone like Jolly Green, Duncan from Race Dynamix etc a call, im sure will know the answer instantly

 

The only thing to bear in mind is that insurance costs on a modded WRX may well be QUITE a bit higher than on the equivalent STi.

 

insurance might be more, but you can't get an sti bugeye wagon, so no other option

 

you need the loom also for the avcs to work

 

no the wrx ECU won't run avcs either

 

I thought the bugeye was the only wagon to come in sti trim?

 

the classic wagon was available as an STI

the newage wagon was wrx only

 

Actually you can get an sti bugeye wagon but they are rear as hens teeth

 

Gary won't be happy with this news.

 

I think there is only a couple possibly one in this country must be a few more in Japan

 

No really Jeff,our wagon has been modded to very high spec and we are paid just under £800 per year for insurance and wagon been insured by Gary@KM

Thanks,Jura

 

Hi Craig

This conversion people done it

Brembo or 6 speed shouldn't be hard to do,but when you are thinking to putting STI engine with AVCS heads to yours then this can be bit difficult,yours ECU can't control AVCS and due this you will need STI or JDM WRX ECU which can control AVCS,loom you shouldn't need,but you will need to speak with Tim@JT innovations about the AVCS loom

Thanks,Jura

 

Nope.... STI Bug wagon's are out there. Fairly rare but I've seen a few for sale over the years.

 

+1

there was a white one on here for sale not that long ago

 

Thanks for all the info guys, Im just looking at options at the mo.

I am happy with 330bhp so may do the 6speed and brake conversion but not do the sti engine. just weighing up options.

re bug STI wagons there are only 4 in the UK and I have the interior out of one of them.

 

I don't think the genuine sti wagons had brembos from what I recall.
but I've only seen a few pictures of one on here

 

Heres some pics of her at the moment, over the winter she will be getting a saloon wide arch conversion on the rear, 6 speed setup, brembos, lowering a little more. may get rid of the bonnet spacers too not sure yet.

 

Your right mate they didnt come with brembos.

I was going to keep the sti saloon but after japshow there ten a penny, I thought a tidy tasteful wagon was a little rarer.

 

if you have a saloon can't you just swap everything including loom and ECU over??

 

yes I could do mate I'm just trying to weigh up the options

 

id say a donor car is the cheapest option rather than sourcing parts separately.
added to that you can always put the wagon running gear in the saloon and sell it on.

 

Yeah plenty of options, I am going to run the saloon for a month or so and make sure what i want to do is correct. Ive put a lot of time and money into the wagon now and I do like it. But its just lacking in power.

I have the following mods to add to her as she is:

VF35
800cc injectors
STI Inlet with TGV Delete

So may just fit those and then sell on the STI lump. If i break the car at all.

 

Lovely looking wagon that fella

 

Cheers mate, shes getting there slowly

 

I'm not normally a great fan of the wagon but yours looks very nice.

Go for it, I'd say.
