GC8 - V7 STI drive train swap

[A_Tiny_Chipmunk]

Hey guys,

Let me start off by saying theres nothing wrong with the parts in my car, I have just been offered a very good deal on a v7 STI drivetrain inc motor for cash + my stuff.

Is there anything that is going to be a big gottcha doing this swap? doing it all, motor,gbox,cv's,breaks,diffs etc. Comes with ECU and wireing loom.

Parts out of a crashed v7 STI

One question I did have is my GC8 (1998 v4 JDM) comes with an airbag would I still be able to hook it up?

Also I have Coilovers from what ive googled they should fit?

Cheers guys,

Aaron

You should be able to sort the airbag setup as they are on seperate ecu sytem, maybe a bit of work but should be able to splice into any required wires if you have the relevant wiring diagrams. The dash and wiring harness will be the biggest/slowest job to graft nicely into each other. Suggest fitting a LINK ecu so that you can elimate alot of the factory sensors and shit that could create warning lights or limp home mode occuring.

The v7 is 'widetrack' and would require all the hubs, axles, arms and preferably cross members to make bolt in easy or your'll be stuffing around trying to make axles work (different lengths and splines) If you use the v7 hubs then the gc8 struts run different bolt pattern but most guys seem to butcher then and make them fit up.

Intercooler may have to be changed too depending on strut brace or if you want to reshape firewall.

There will be lots of little annoying bits, but ultimately will depend on the use of which gc8/ver7 parts are used.

engine: everything fits, you will also need the power steering rack and line from the v7, as for topmount make sure u get the remote clutch thingy that sits on the firewall that got the clutch pedal too unless you doing front mounts

gearbox: fit, make sure u got the hubs and diff problem will accure is the brembo hopefully u got a 4/2 pots brakes already? and wheels that will fit over brembo brakes

wiring/loom: fit if u got a full loom and dashboard u can do a swap conversion just have strip everything down and get the what u call it i cant remember bar that go under the dashboard modify, this way you can use all the wiring that comes with it. this is how i done mine. the other way is to merge the ecu to your existing dash wiring which isnt so hard to do but can take some time. heres how you can do it: http://www.rs25.com/forums/f128/t141937-brydon-teaches-you-merge-harness.html or you can pay someone to do it... you dont need to buy an expensive link unless you are rich enough to do so... but if you are planning to do the merge make sure u keep the OBDII plug for reflashing/tuning

this is my car here but with V8STI mods
