Title: 1.8t conversion
Post by: 67buggers on 20 July 2012, 18:39
I have had a garage offer to sell and convert my car to a 1.8t engine for £700.... But theyre are on about using the mk4 box and drive shafts.... I have only read about people using 16v gti mk3 boxes.... Us this doable?

ive read people use the mk4 box, £700 sounds rather cheap though, are you sure thats right?

Yeah £700 drive in drive out but would put me on 5 stud so still need to cOnvert back to 4 stud.... Mates rates and there cheap as chips anyway

700 is nothing....

I just spent £500 on the exhaust alone  :undecided:

Well you need a custom downpipe made up, which isn't standard and 2.5" bore, so you need to really get a whole 2.5" system.

Im not sure about doing it on standard exhaust.

700 drive in out is mega cheap  :tongue:

Have a search and do a bit of research first  :smiley: F17 BAD has a thread on all the parts you need  :smiley:

I read F17's a while back and decided on doing a 16v to start and aim for a 1.8t at a later date.... £700 seems to good to be true. I will check out his plans first!

for £700 the garage would surely lose money over it unless its a very shoddy job, I know I wouldn't wanna drive it! Even if they had a free donar car I'd bet it would cost more than £700 and that's without even charging for labour
Title: Re: 1.8t convertion
Post by: Dan_GTi8v on 20 July 2012, 21:07
also pretty sure mk4 driveshafts are a different length to mk3 ones, to use a mk4 box you need to change the input flanges on the gearbox to mk3 ones

The standard of workmanship for £700 would worry me.

Seems mega cheap, parts add up to more than that!

That does seem ridiculously cheap.  :huh:

Its a vw breakers by me who also build and repair in there workshop, the engine and other bits he said will cost me £500 then £200 labour.... There doing some minor bits for me today so i will do some more digging
Title: Re: 1.8t convertion
Post by: CJA321 on 21 July 2012, 08:27
£200 labour?! I certainly wouldnt do it for that  :grin:
Title: Re: 1.8t convertion
Post by: lemski on 21 July 2012, 09:05
200 labours 10hours at my garage. I charge 400 if they have all the parts already. I think so far I've spent 100 pound as I bought a full a3 for 300 and broke it for spares.

Not really something that should be done on the cheap and £200 is stupid money that suggests they are going to bodge it.

Title: Re: 1.8t convertion
Post by: F17BAD on 21 July 2012, 23:22
way too cheap

anyhow

MK4 box will fit (as i have a bespoke box in my car now but it is based on a MK4 item)

MK4 driveshafts only fit on the passenger side, drivers side (long side won't fit as its longer on mk4 4)  - I also know this as this is what i run on my car. MK4 GTI on passenger side, drivers side is MK3 16v

Post by: Shady Pioneer on 21 July 2012, 23:28
What's a convertion? I'm guessing they are offering a different service to the 1.8T conversion you're talking about. :grin:

Anyway, seems way too cheap, sure they aren't just gonna stick a 16v engine in and a 20vt cover to go over the top?

I cant honestly see how you can get it done that cheap. If your starting with a 16v would be cheaper obv. How much was your exhaust and things?
Title: Re: 1.8t conversion
Post by: Gash on 22 July 2012, 16:28
mine was a 16v so hense why cheaper.
my mate whos doing it for me did a conversion himself into a mk2 golf and worked with vws for 10 years so i know and trust him for it to work.

all the things you need...
mounts-got
exhaust-got
gearbox- got
ecu (managed to find a unlocked/remapped for £95)
downpipe he had - 50
lightened flywheel - 50
intercooler - 20
piping - 70

so 890 roughyl :D

Title: Re: 1.8t conversion
Post by: F17BAD on 22 July 2012, 20:49
what about TIP ?  approx £100, diverter £100 (unless u get a copy or use bothe the standard TIP and diverter - bab tho)) Air filter £100 (unless u get something sh!te and restrictive?  

VR6 clutch?  could use your old valve one but thats just cutting big corners IMO

New engine mounts ?  again cutting massive corners using old ones

New stretch bolts for flywheel ?  around £30 new bolts for clutch £can remember

All the new gaskets for engine manifold, turbo TB etc etc

New service parts, decent oil, filter, Coolant (G12 plus plus) non of this is cheap - appros £100 their

Cambelt ?   Waterpump, ? tensioners ?, Aux belt ?

loads of bits off your list you have missed unless you are cutting huge corners which i would not personally do

 :smiley:
Title: Re: 1.8t conversion
Post by: Gash on 22 July 2012, 20:54
dont count the service bits seeing as they would be needed anyways.
i just meant the big things
Title: Re: 1.8t conversion
Post by: F17BAD on 22 July 2012, 21:14
all adds up pal..at an extortionate rate too  :laugh:

theirs other bits you have missed too depending what engine code you have.. so i would'nt expect it as plain sailing (no pun intended haha) as you think  :smiley:
Title: Re: 1.8t conversion
Post by: Gash on 22 July 2012, 21:18

Title: Re: 1.8t conversion
Post by: lemski on 22 July 2012, 21:38
I've got trade accounts, still she adds up quickly. But it can be done cheap enough if u get a bargain of a donner car
Title: Re: 1.8t conversion
Post by: LazyLunatic on 22 July 2012, 22:13
I agree with kells. There are loads of little things that add up and if you want it done PROPERLY then it costs much more. If I was to do it again, I'd want to replace all the sensors with new genuine, same with pumps, gaskets, belts, etc. Saves a lot more hassle down the line, trust me!!!

There are loads of 1.8t conversion's on here now too!
Title: Re: 1.8t conversion
Post by: F17BAD on 22 July 2012, 22:22
yeap i changed everything on mine, and do the same on all others i do now because recently we did a mk4 non turbo to 1.8T using customers own donor etc, i told him to change everything but he wanted cheap option and just to swap it all over so thats what we did

i did clean it all so it looked ace but i told him i was not responsible for sensors or belts going wrong. also told him the K03S was passing oil quite bad and needed rebuild which is much easier to do when engine is out of the car...

guess what, car has been nothing but hassle with sensors going wrong, leaking turbo which i told him to have re built (£ a few hundred quid !!) no boosting issues due to split pipes etc.. all stuff i told him to replace..  :rolleyes:

he is now having to do stuff which would have been p1ss easy to do when the engine was out and regretting not taking my advice


Do it once, do it right... cutting corners = a fail at a later date and a fail = Regret  :laugh:

Sound advice but I doubt anyone will listen.

I can vouch for that advice! I learned the hard way and have had most things go wrong. On the plus, I have learned a lot and don't make the same mistake twice (maybe twice, but not for the 3rd time :D )
