I'm seriously thinking about doing a 1.8 turbo conversion but have never done a conversion before. What do I need to do the conversion?
I mean like what parts do I need in total?
-
I'll try and dig up my shopping list when I did mine
-
this is just my list, I'll look over it in a bit as I'm in the middle of cooking dinner atm :grin: Obviously some things are up to you and the code can be any transverse 1.8t (as opposed to longitudinal fitted ones like those in the U.S)
*Cable to hydro clutch parts (master cylinder, slave cylinder, and fluid lines)
*Engine and Gearbox brackets
*Engine and Gearbox mounts
*Engine AUM
*Gearbox 02a
*Intercooler
*Boost pipes
*VR Clutch
*ABF Flywheel
*Downpipe from QPeng (ask Kells about his though, same price and better quality)
*Sports cat (for no messing about at MOT)
*MK4 PAS Pulley
*SAI block off plate
*Forge TIP
*Forge 007 recirculating diverter valve
*modified loom (give rubjonny a pm or I think topher knows someone who can do it as well)
*ECU immob defeated and 2nd lambda mapped out (Topher did this for me along with a stage 1 map)
*16v starter motor
I'll add to it as I remember anything else :)
There will be many things you forget about or wont know you need until you come to it. I started from an 8v GTi, ideally you wanna start with a 16v as a lot of the work will be done for you.
what are you starting with? anything under a GTi would need other stuff as well such as bigger brakes etc
-
I will be starting with my 8v gti. Have been thinking about more power for a wile.
Debating weather to buy a VR6 and transfer all my mods over to it or to do a conversion to mine.

That thread is pretty useless really
You will need more than above too, new engine mounts and a exhaust with a 2.5" bore like jetex are a must.
It's no cheap game. The VR6 route would be easiest and cheapest

Yeah but it's just the fuel cost after though.
-
Anyone can go out and buy a VR6 :P
I'd say its worth doing the conversion not only because it will be a 1.8t! but doing it yourself you learn a lot about the engine and how it works, with my 8v it was always a bit of guess work and forum searching trying to find solutions to problems, but now I can say I know what 99% of the stuff under by bonnet does, where all the pipes go, if I do get a problem I know what the likely causes are and how to fix them :)
One tip I'll give toy if you do decide to go for it is plan to spend over your budget :grin:
-

Worth remembering a 1.8t remapped is not that much better on fuel. :smiley:
-
mine on a stage 1 is about the same as my 8v gti but I also have a pretty bad boost leak somewhere that needs sorting.
ATM I'm trying to find a local vagcom so I can check my fuel trims, probably end up buying one though as I can see myself needing it quite a few times to see if its getting any better. If you do the conversion adding vagcom to the list of parts needed would be a good idea :laugh:
-
why do you have to imob the ecu dan? if you do complete swap of loom???
-
You just do or it won't work, its coded to the immob of the original car is the ECU..
had to have my S3 ECU immobiliser defeated too
-
If you have keys chip,ecu and complete engine loom from donor car and swap everything why would that not work?

The immob is built into the clocks on mk4.

That is where the tricky part comes in! I had to help a mate with his immob on his MK2 Turbo conversion.
I have found with easy driving that I can get 25mpg and on a good run 32mpg.....Same as my old 205 1.9 GTI regarding MPG except my VR6 is a lot faster! Best yet is 147mph (Sat-nav reading) speedo showed just under 160mph (This is on a private bit of road I must add) I have a few mods like a full s/s exhaust, de-cat, modified airbox, direct feed and breathers.....But that is it, no super charger or turbo just 6 angry cylinders :grin:
-
yeah and the vr does have a lovely sound when breathing right.
remember my 850 T-5R after the mods was getting 19 mpg if i drove it sensibly.
i could afford that back then though. acceleration was stunning and with dv36 bailey dump valve and boost high had the loudest dump iv ever heard. scared the fcuk out of people :cry: god i want that car back :sick:

Is that all from a vr? My 16v has just been recorded at 151mph at 7100rpm on my sat nav because i got lost on my private run way :sad: (160+ish speedo went off so dont know) next month its being parked up for supercharger time :D
-
fastest iv been was in the my yellow t-5r and that was 162 but the roundabout on the private road came at me so had to start breaking. the amazing part was how fast it got up to that speed in.

:laugh: roundabouts are annoying on these private run ways im just glad mines the same size as the m5 or i'd have no chance :sad: those t5-r's are emmense mate i wanted one once but unfortunately insurance destroyed my plans :sad: now im happy paying £435 a year for a car that will polish off some new hot hatches :smiley: its not the fastest by all means its not the best either but i love it for now and to see peoples faces in 20k cars thinking they will win by ease is priceless :smiley:
-
Will your cars actually hit 7k in 5th? Mine wont rev more then 5.5 ish @ speed 120. GPS, not sure.

:undecided: Autocar roadtest recorded a top speed of 134mph so what has yours had done to be that quick :huh:
-
I've had 2 valves and both struggled to hit 130mph
I've done a 140 in a VR (they are good on the motorway)
The S3 bad car is just insane, I've had it to 150 with LOADS left to go ( ran out of road ) and this was on a uphill!! :shocked: :evil:

Same as bud.....I got 131mph from my Valver and that was at its limit.
Is your S3 mapped? A mate of mine has an Audi S3, lovely car.......An S3 engine in a MK3 Golf with the power going through the front wheel must give a huge grin factor!
Stainsey..... I will call you a bit later bud, number will come up as witheld!!

Ok fella. Yeah give me a bell when ever mate I'm up and awake with hangover now lol.

yeah i loved the look on peoples faces when my yellow volvo estate destryed them.
this was my beast. spent thousands on here. was so proud of this car

those T5R volvos shift.
for 20vt conversions iirc some of the really eraly 150's used the same immob setup as the mk3 golfs littel immob box on the data line between the ecu and obd port, think it was the early audi A4 so can make conversion easyer pitty nothing much else is usefull from the audi
-
Is your S3 mapped? A mate of mine has an Audi S3, lovely car.......An S3 engine in a MK3 Golf with the power going through the front wheel must give a huge grin factor!
it has a base map at the mo, so it is around 250bhp /280 odd ftlb, we are struggling to keep it held o the rolling road (its trying to jump off when the revs get to the top end :evil:)
but carbon have a few ideas so its going back in a couple of weeks for custom mapping, the power will rise. next year its BIG turbo upgrade time
its a great car, MK3 shell copes well. It is stupid fast. i love it
-
I always wonder when I see or hear about mk3s that have more power than mine, I know I dont have amazing power but I cant imagine a mk3 going faster it must be mental :evil:
-
Stainsey....
These are some of the engines up for grabs on the VR6 forum......
1. Obd2 2.8 vr6 engine, cammed, Vortech V2 charger and united motorsports ecu running 280-300 bHP 155k @ £2,200
2. Obd1 2.8 vr6 engine c/w T3/4 turbo, short runner, intercooler, pipework and storm developments ecu running 350-400 BHP 135k @£2500
3. Obd1 2.9 corrado vr6 engine 145k £200
I think the Raddo engine would be a good choice as they are 190bhp standard and almost all of them when RR'd produce 195-200bhp. Only thing is though all Raddo VR6 engines were OBD1's so dont know how the wiring/engine management would be on your 8v GTI?
-
Tbh mate if I was going to do a vr I'd rather buy one and swap my bits over than fcuk about with doing engine. Anyway scrap the idea of power I am now obsessed with getting some deep dish rims for my mk3 and I want to buy a mk2 to put in my garage and strip it down and rebuild it. After seeming some at the show I really want one again lol. And I will have one lol.
-
1.8t mk2? :evil:
-
1.8t mk2? :evil:
Could well be. My plan is to get one abd strip it down to shell then start from scratch. May even swap my mk3 for a mk2 if anybody fancied my car.
-

That is one stunning MK3 Golf you have as well bud. Full leather, coilovers, full s/s VR exhaust, Vento front end......Soooo many mods, this car has to be seen!

is there a complete list anywere on here?
-
theirs never gonna be a complete list as it depends on each car/ engine code used etc and how far you wanna go.. those are the basics tho
also factor in the exhaust as you really do need a 2.5" bore system (Jetex) and these are pretty expensive unless you already have it

okay then cheers, wheres the best place to get the jetex system from?

www.ebay.co.uk :P
if you are gonna be getting parts together over time it could be worth checking every now and then for a 2nd hand system on ebay, wont be rusted as there stainless so imo 2nd hand is just as good as new as long as the tail pipes are not scratched or dented
-
Thanks Wayne seems a bit obvious now lol.

Yh Im planning to start buying stuff for it just after Christmas. Yh will have a look on ebay. Love grabbing a bargin lol
-
mate i found the cheapest place for the Jetex is Venom motorsport, bought mine here and one for a MK4 here too. Im also getting the one for my MK2 20VT conversion at Venom too.. both times iv had the others they arrived in a couple of days direct from Jetex factory
-
Ideal cheers bud. Can't wait till Christmas is over so i can start getting stuff for this. Seems like I've bin waiting forever to start it.o well will be worth it in the end

Getting common now these 1.8t conversions :p

Meens i can get lots of help :smiley:

was you at e38? pretty sure I drove past you on the feild?

A little bit of info for you, they are made in Sweden and are only know as Jetex in the uk.
-
ahh right cool, wonder what they are called in the EU ?
mine came from a UK destination, must be the UK Jetex Warehouse
