145 QV 3.0 v6 conversion Options

[Col]

Hi chaps,

My twinny has bitten the dust so I've opted for a v6 conversion. I've bought a phase 1 gtv donor car which will be here in a few days. Does anyone have any tips going forward? Has anyone on here done this themselves? I've done conversions before but maybe not on this scale.


Thanks

Col

I'll post updates as I go in case anyone fancies doing this themselves too.

This is my 145, as I said above the engine is knackered so time for a nice big replacement



The donor car arrived this morning...




Let the fun begin

Good luck with it...I'm not gonna be much help though

Watching with interest, was about to scrap my V6 155, suppose the engine could go in the 146, wouldn't be any faster but the noise would make up for that

Started on things today, not much done really, it's up on stands, car cover on, one corner stripped and in a box. I'm going to replace as many parts as I can with new parts, lots of powder coating and all new bolts from my local Fiat dealer.

As the front calipers need serviced (they were in the boot when the car arrived) I'm going to try for 330s under 17" GTA teledials on the front and just replace the calipers on the back, they look a bit knackered tbh. The donar car came with KYB Gas A Just shocks which I assume are just cheap OE replacements. No use to me as I've already bought coilovers.


I'll post more soon

You could always upgrade at a later date to 3.0 or 3.2, you have all the right bits sitting there tho

Back to it today, got the rest of the rear suspension off an started sanding the sub frame. Check out that box of manky parts.

Time for a cuppa

Today, not so well :/

[Col]

Just more stripping for now, been raining a bit here too so progress has been slow the past few days. I had to file a 36mm socket to get the driveshaft nuts off, complete pain in the a**e.

Hopefully tomorrow I'll get everything prepped for taking the engine out on Sunday, I need to get the GTV off the drive before my neighbours start complaining.

[effkay]

Unlucky with the wrench. Making progress though. Keep it up and the pictures coming!

Almost ready to take the engine out...

[Col]

So the engine and gearbox are out and the GTV goes away today. I've tried to remove as much as I can and I hope I haven't missed anything. I found the battery cable that runs from the boot to the wee box in the engine bay so I think I'll mount the battery in the boot of the 145.

Most of the strip was pretty straight forward, the only things I hadn't come across before were the driveshaft bolts, they were a pain in the a**e. I cut the front cross member out and the end of the chassis legs so the engine came out easily enough.

The new parts are starting to arrive, so far I've bought the coilovers, front track control arms, track rod ends, front hubs, front wheel bearings, inner and outer cv joints, rear tie rods, rear drop links, rear hubs & bearing, rear top arm ball joints. The bill is starting to get a bit over the top so I've decided to go with the 305mm brakes for now, they're going for a refurb and a paint instead.

So the next plan is to prep all the parts for powdercoating and get them away, then I can start to strip the engine and gearbox down. New clutch (and possibly flywheel if it has a DMF), timing belt, water pump, tensioners etc. Heads skimmed and gaskets changed, new plugs etc. and generally get things all clean and shiny again

Once all that is done, I can go and collect the 145

Does anyone know if I should use the GTV steering rack or stick with the 145's?

(The cardboard box is to remind me there is jaggy stuff under there lol)

[Col]

My tip for the driveshaft bolts is an impact gun. I tried to use it as little as I could during the strip, trying to be gentle and not strip anything but I don't think I would have removed the near side driveshaft bolts without it.

Looks so fun.
Have you salvaged the harnesses among the engine,ecu,and immobiliser or planned to obtain or fabricate new one?

BTW my battery is located in the boot,the engine is still twinny for the time being tho.

Easiest thing for the front end is use the entire GTV Subframe / struts / hubs / rack etc. That way you wont have any issues with selecting the correct track rod ends in future etc if they are any small differences.

Cool, that makes sense yeah, I'll add a new rack to the list

Yeah, it's all in the shed the garage I use are going to wire the 145 up once the new engine is in, they'll pretty much tidy everything up.

[AJ]

Good progress! The wiring should be pretty easy, but you'll need to cater for the 6 pulse input to the dials (if it bothers) you, as the dials will expect 4 pulses, so you RPM and speed will read higher than they actually are - there are various pulse converters available now, I'll try and find the one my friend used on a kit car. I'm sure you got it but get the gear linkage - I can't remember if the GTV is rod or cable

[AJ]

I'd like to see the rear suspension from a GTV fitted to a 145, I bet that would make for some awesome handling

Also.... I hope you have remembered the fuel pump!

I have a brand new FSE fuel pump for the 3.0 v6
