I'm going to be adding the 20VT lump with drivetrain into my alfa GTV.

After blowing up my previous engine twice and replacing it, I think I may as well add the engine it should have had

So you'll see me much more, with questions and progress updates etc.

PS, i'm going to be aiming for 300 or over bhp and been reading the tuning section for a while now and it seems to be an easy target to reach.

ooops, posted it in the wrong area

Welcome to the forum.

Hi and welcome

Hello and welcome to your new home.

Interesting project, i'd be keen to see how this one pans out.

Are the engines similar in mounting arrangement?

I was considering an Alfa V6 transplant into my 20V N/A

Welcome along. Nice plan and I'll enjoy watching your progress with it. Create a build thread in the projects section

Exactly the same, should be a straight swap but the wiring is the hard part si I decided to go omex from the start and get them to supply me with a harness.

If possible I should have it in and drivable in a week just need to source the parts first and that's will take a little longer.

Will go FMIC as I am sure the GTV bumper has huge space behind it although not that high mind.

Also the price for Garrett GT28RS turbo chargers seem to be quite reasonable as well.

I think I have o be here for a certain period before I can do that, but once I can I shall

Why not make it REALLY interesting...

oooh, now that does sound interesting! Slight over my initial budget mind, will have to see if I can stretch to that

Just done a quick render of what my dream here is



Yeah, probably a tad tacky

hey bro welcome. good luck

OK, started organising the parts I need, contacted omex about the ECU and pricing and it's a tad expensive to say the least but worth it I think.

ECU is 845 alone and harness is between 450 and 550, couldn't get a more definitive answer then that.

Brakes (Pads, discs and lines), Wheel bearings (yes mine are FUBAR) FMIC ebay special LOL! Walbro fuel pump, IIRC, this is compatible with the pump housing in my GTV.

I have 155 V6 coilovers on my 155 twinny with coupe 20vt hubs, new TREs and track rods all hiding in a garage in south London LOL. Need to buy some adjustable rear shocks as the 155 rears are not compatible, think the springs are though.

Then it's finding a donor 20VT coupe willing to donate it's heart to my GTV

ECU £845
loom £450~550
All brake parts approx £320
FMIC kit approx £150
Walbro 255LPH fuel pump £70
possible uprated fuel pressure regulator £30~90

Donor Coupe £ anywhere between £500~1000 please

Gonna be expensive

Why not use the ECU and loom from the donor coupe?

Welcome! I thought I recognised your signature, Alfa Owners I guess?

Seems to be a common thing people putting 20VT engines in other cars.

Am I the only one who'd put an Alfa 3.0 V6 in the Fiat Coupe.. ?

No.

Because I don't have the time or space to keep the donor around for more then a day or so, just won't have the time to rip the harness out, that and the time to splice it into the GTV as it is my daily drive so I am wanting to only have it off the road for a week or so.

Would be nice if it was simple eh!? LOL

Try contacting Joe (countrycruising/FCSS) he could probably sort you a lump+loom+ecu etc for less than you are planning to spend on the ECU alone.

01885 400740

Let it ring...

Thankyou, I'll be making a call in the morning

joe has all the stuff mate and he would be the first point of call for this sort of project if i was doing it

3l v6 busso in a coupe, now that would be interesting!

Yep, long time member on AO LOL!

In Bulgaria there is a Alfa GTV fitted with 20V Turbo engine from Coupe!
There (in BG Alfa forum) are lots of pictures and you may find useful!
You can write and the owner, if you have specific questions.

I'd echo the previous comments about a complete engine/harness/loom. The engine-ecu loom has a single fat loom - it's an inch or more thick - but only half a dozen connections to the main loom.

On the kit conversion I used effectively all the loom and the matching fusebox, and just spliced the front-to-back loom to pick up the rear lights and speakers. That might not be as effective on the Alfa since there are probably a lot of Alfa-specific ancillaries.

From memory there are a number of looms:
1) engine-ecu (sensors and signals, mostly, and starter and alternator)
2) engine compartment - cabin (power, lights, alarm etc)
3) fuse box - rear (lights, speakers, heated rear window, control box for interior lights, electric windows, and locks)
4) fuse-box - instrument panel (instruments, front speakers, console switches, fan/aircon etc)
5) instrument loom to door looms (x2) with locks, window power, door switches, speakers
and a number of other smaller looms for things like ABS, Airbags and so on.

I would strongly recommend joining the club to get access to the high-resolution manual - you *will* need the details in the electrical section at the very least. There are detailed descriptions of each subsystem, all connectors, and the positions of the parts in the car. It's critical...

Only real issue I can see is that the gtv has service relays in the boot where normally they'd be under the bonnet/drivers footwell. How much is it to join? Think I'll do it when I get home tonight

About a percent of your initial budget... fifteen quid.

Brakes ordered
brembo discs front and rear, stock rear pads for now and tarox fast road for the fronts.

Tomorrow I'll get the suspension, hubs, tres and rods from my 155 lurking in the south and then wait for the brake components to show, then i'll fit the at once and have 305mm on the TS till I get the donor coupe

Ok I couldn't get the damn coupe hubs off, well I couldn't get one off so just left the other. But I did get the shocks at least.

Found my coupe brembos and I'll see if I can refurb them otherwise it's use the ones I just bought and will receive next week.

Need some coupe hubs!

These came to my work today

Brembo OE discs except they're for the 3L so 305mm for now with tarox fast road pads and standard pads on the rear. All in all set me back £308 Bargain



A parcel is at the depot for me to collect, I suspect it's another set of Brembo callipers as I bought another set incase these don't refurb too well

Well my 2nd TS engine went pop this morning so now it's all about getting the coupe engine and parts now :lol:

Watch this space

Ok, been offered a 16vt setup currently pushing 260bhp with everything to make it work for a decent price so I took up the chance hopefully I'll have it by me this weekend and the fun starts!

OK, 16VT donor comes tomorrow

welcome to the forum mate happy couping

Thanks

Here's my callipers, still require decals but,

Got the donor and almost feel overwhelmed

Fitted a few GBs and an engine in my time, but never a conversion.

I'm good at electrical, but this looks a bit oooh errr

Wimp: I went from this:



through this:



to this:


In about three days of work...

I got a day and a half without knowing what I'm actually doing LOL

It's pretty good - there are very few places you can plug the wrong connectors together (but watch the back of the engine). The diagrams are *almost always* correct with respect to location and wire colour.

Cool, I was going to label most of them and recover the loom before refitment. I did expect it to have more wiring mind.

cant wait to see this finished!
Best of luck! your in the right place for help and advice

Make sure you get it down the ace

Only missed the Ace about 6 times in 4 years

Engine top loom
Engine-ecu loom
Bonnet loom
Engine-fusebox loom
Fusebox-instruments loom
Fusebox-rear loom
Fusebox-dash loom
Airbag ecu loom
AWB ecu loom
Center console loom
Left door loom
Right door loom
Sunroof loom
Heater ECU loom

And possibly one or two more I forgot... should keep you busy.

916 . . . I think you should PM begbie and get a project thread set up for this

Best Idea mate, Thought I'd be able to create a thread after a probationary period or something

Nah your project is well worthy of one, send begbie a PM and he will sort it for you

Already done mate

OK, got the ECU engine loom out, stripped off the old fabric tape and recovered in amalgamating tape.









I'll pop into Maplin tomorrow to get some stuff to finish it off nicely, Engine will be black, hoses and wiring will be yellow as I'll be wrapping my GTV white

Engine almost out, started tipping it down so I went inside after 10 mins and got soaked


Labelling the connectors for easy refitment and tidy install


This is the only interaction this loom has with the car's main loom
