Potential V7 STi engine into a V2

[deathz0r]

As per title I'm thinking about doing the above - and on a budget!

I can get my hands on a V7 STi ECU and potentially the loom (lets just say I have it). What would be my cheapest option of getting this up and running?

People say the wiring would be a nightmare and others say just fork out for a Link (or other standalone) - but of course thats friggin' expensive.

Any suggestions?

Cheers

Have you checked TM for any second hand links?

Do you need the latest G4 Storm or whatever?

[deathz0r]

Yep, all still well over $1k. I don't have that sort of cash atm as then theres the tune on top of it too.

Im pretty sure San has done this into his version 5? STi and he used to v7 loom.

Pics might still be up on his FB page.

He is a mad scientist though!

If you've got the ecu, loom and complete (full) motor with all sensors. Just change the whole loom over and drop the motor in.

Does your current ECU sit near steering colum? If so make sure you have room in the passenger foot rest for the new ecu.

Ver 7 ecu can be reflashed, so negates the need to fork out for a Link.

The wiring isn't that bad once you take out both front guards, and the dash assembly. The only issue would be the airbags - as your car doesn't have them.

Are you doing the whole dash and interior too?

has full loom and ecu

[rex-leggy]

his ecu will be in the passengers foot well. do it bro im sure jon will give ya a hand

wouldnt you go standard ecu because there remapable?

[funkytown]

haha its taking the 7 engine and loom from the car you saw man

(and you know we flat together rights, so as soon as the 7 shell is gone, his is being wheeled in)

[rex-leggy]

yea thats wat i thought ;D . so ill say again doooo it haha

speak to san he is the man.

ive seen pics on his FB of him doing this conversion...albeit with a v5?

Concur, bitta bad form there to be honest.

I agree

Just do eeeeeeetttttt

And take pics with notes for a write up!

[deathz0r]

Yeah I'll prob do a write up. And yes, I think I'll get San to do it - seeming he's done something similar not long ago.

Jason - no, no airbags or any interior stuff, literally just the engine to be all wired up etc.

And yeah, may of been semi bad form but when I guess the sale of the motor lingers on it... Hmm. I'm sorry but yeah, sucks. I know you were thinking of running a link - this should be an easier option for wiring anyway.

Link is over rated.. and yes i have the full setup in my but not ver7sti but a customized ver8 sti engine

wiring.... easy as piss... i should have all my notes somewhere... wiring will take about 20-40 hours to do... but time flies when we having fun...

i would love to give this another go at it... im not expensive so dont worry too much what im going to charge

i got a ver4 not 5.. if i had a 5 it would be a lot easier to do the wiring

i'll talk to you later when you are ready to go... i need you to get and print out the pin out for you ver2 ecu and ver7 ecu

be good if you do a write up on it.. ive done a small write up on but on another forum

[spark_38]

20-40 hours?

I best come along for support and bring the coffee machine too...no, it's not drip coffee!

by the way you will need both O2 sensors also... if Funky sold it already i got spare ones

[deathz0r]

o_O

I'll just take your word for it San hahaha. But yes - thanks in advance for helping - and Jase, sure!

I'll have both O2's

[ODB]

Told you San is the mad scientist you need to consult!

[Guest]

Jase, where were you when i was doing my one?

should be a sik conversion bro.you guna use the vf30?

[deathz0r]

Yup VF30, will be a complete V7 stock conversion
