Can people list the exact parts and pref model numbers that are needed for a turbo conversion..
superchargers gonna pop so gonna go the turbo route... as it seams more durable and reliable than spending more money on another lader for it to go pop further down the line...
My G40 is in a polo gti... so dont know if it will be different to normal conversion..
all advice and help would be much appreciated
Regards

ah a polo gti - cool. I'm sure someone will comment on what turbos to use.
What I would say is g-laders aren't that unreliable! give them love and they respect you. Like a woman!
-
the basics you'll need are:
- kkk k03 turbo from a 1.8 20vT passat
- rothe motorsport k03 manfold (or a copy from german ebay)
- rothe turbo downpipe for k03 (or a copy from german ebay)
- g40 exhaust manifold gasket, k03 to manifold gasket, k03 to downpipe gasket (all stock VAG parts).
- forge motorsport uprated actuator for VAG 1.8 20vT (standard one is designed to work with an N75 valve which a G40 doesn't have).
- oil feed and drain pipes
- oil drain boss welded onto sump pan
- dump valve of some sort (stock vag recirc is the best type for these turbos)
- front mount intercooler & pipe work to suit (depends what you can fit on the car)
- the turbo is water cooled so you need to tee into the water pipes for the supply and drain from the turbo. So you need some bits of pipe, some t-pieces and some fittings for the turbo. You'll have to just figure this out when you got he turbo on the car and can see which water pipes are nearby to do this.
- ...probably a hundred and one little things I've forgotten about....
Then on top of that you really need to get a turbo-specific ecu remap, ideally a custom one with rolling road time. Depending on how much boost you plan on running you may need a different MAP sensor which will require a custom ecu map to suit.

yeah its in a polo gti which is stripped of all its modern comforts... like climate/power steering/ abs..
its basically a new shell with all the old g40 stuff in it.. pretty different and cool i do love it... its caged up with buckets...

good stuff..any part numbers?? sorry to be a pain mate... as if i dont replace me charger gonna start slowly building up the parts over winter...
-
I'm not really sure what you mean by part numbers, VW part numbers for the stock VAG bits maybe? I don't have them but just ask them for the parts by name.

yah thats what i emant sorry iw asnt more clear will do.. still deciding if i wanna get another charger or turbo it.. bit indecisive at the mo...
-
do you even know for definite that your current charger is beyond repair yet?
You're unlikely to be able to do this turbo conversion for less than £600 I reckon. Unless you manage to find someone selling most of the parts for a very cheap price.

um no i dont kno for definate mate but the way i was looking at wa sthat if i have to spend around 600 more than may aswell b patient and do a turbo conversion and try and do it for around a grand or so... but than that means the car being out of ocmmisons for pretty much winter which isnt a bad thing but its disheartening knowing it doesnt work...
-
Heysey forgot to mention the cam. A stock GT one is better than a stock G40 one, but a turbo specific one would be worth buying, I think a couple of cam manufacturers (e.g. Newman, Schric) do them.
-
not sure I agree with the GT cam, I think a stock g40 one will be better. gt = too much overlap. Obv a turbo specific one would be ideal. I'm hoping someone who bought a PSD "turbo" cam will get it measured up at some point.
-
Nah, with a K03 a GT cam is miles and miles better than a stock G40 item, tried and tested.
The PSD turbo cam is better still, but I keep meaning to measure mine up and have a think about whether it could be improved upon.
-
hmm interesting, was told pretty much the exact opposite by someone else (yoof I thought...)
-
Were you both pissed at the time? ;D
-
lol, nah. I was talking to him about it on msn a while ago as I was under the impression before then that I'd be better off putting a gt cam in but I thought he was saying the g40 one is still more suitable to use with turbo.
I guess I'll get a gt cam and see how it goes then!
-
GT still isn't great, but it's a cheap way of getting up and running. I'd like to try a 268° GT cam to see how it fairs.
-
I want someone with a PSD turbo cam to get it measured!
-
I can try and find out mate.
-
psd turbo cam is just a newman cam so can you not get the details from them?
i need a turbo cam too when i was talkin to steve (pitstop) a long time ago,
he was telling me the stock G40 cam is good up till around 4k then its like hitting a wall
the GT stock cam is better all round but still not great then he said he can still get hold of
the newman cams for about 140 pound. an this was after he finished up with pitstop.
maybe a newman group buy???
-
A Newman "turbo specific" camshaft group buy sounds like a good idea.
Can anyone get in touch with Steve Pitt and find out anymore details?
I'm sure Steve said there were 2 profiles available, one being quite aggressive and being more suited to full on race spec engines?
-
Even if anyone could manage to get hold of Steve, he won't tell you the specs of the cam. I quite reasonably wanted to know what I was buying when I got mine, but he wouldn't say!
Newman told me it was their normal 268° symmetrical cam for N/A engines, but I think that's bollocks.
You'll find on a K03 turbo setup that a GT cam makes the car driveable compared to a G40 cam, but even then it'll feel choked at higher rpm (around 5k from memory). The turbo will spool at 1500rpm with a GT cam too, which makes it kind of frantic to drive - good fun if that's what you want.
-
Looks like ill be forking out £250 for a shrick cam from G-werks then :<
-
ill try an get hold of him,
so if someone rang up newman they wouldnt tell them the score with the cam?
you would think they would wanna sell some still???
-
you'd probably at least have to tell them some sort of serial number or part code off one of these PSD turbo cams for them to be able to identify it. Just saying "it's a psd cam for a turbo" isn't likely to get anywhere, I doubt they'll just remember what it is.
But it'd be great if someone who has one could tell us any numbers off it? Maybe I'll go and take yoof's out of his engine while he's asleep?
-
ha ha yea they prob make a few cams eh lol,
yea you do that an give them a ring with the numbers,
has nobody got one then to measure up or get numbers from?
im going to need one in the next few month
an id at least like to know the numbers incase one comes up for sale
so i know am not buying a 1341 cam or summat.
-
i know the shrick item im looking at for mine is 268/264
I just had a look at newmans website they dont do a great deal of VW cams.
-
As I said previously:
"Newman told me it was their normal 268° symmetrical cam for N/A engines, but I think that's bollocks."
I told them I had a PSD turbo cam and wanted to know the spec. I might try again with the serial number from the cam. It's cold and wet outside at the moment though, so I'm not getting the number off it now!
-
Yeah that'd be good if you could find out Andy.
Failing that, Lance can you try and get hold of Steve? I can't see why he wouldn't be willing to give us the part number seeing as he's not selling them anymore?.
TBH, it all seems a bit stupid all this secrecy lark, not divulging information that would help other enthusiasts. I can however understand Newman/Steve Pitt keeping the exact measurements to themselves, buy why is it so hard to get a flipping part number? >:(
I'd personally far rather use a Newman cam that Steve Pitt/Newman specifically designed for the K03 turbo'd 1341 engine. The Shrick ones are a lot more money and who's to say that they are ideal for our K03 setups?
-
When I put together my K03 1341cc it was the first one, I took it down to Steve for mapping at the same time as John Marchant's old Mk1 K03 1272cc was there. Steve'd had a couple of 'turbo' cams made up, having tried a 3F cam over a PY one on my recommendation but still finding it lacking.
As far as I know John got one cam, and I got the other. Whether the other 'turbo' cams Steve had made are the same spec I don't know.
I asked Steve the spec at the time, and on multiple occasions since. I believe the lift's around 10.5mm but that's all he'd say. It pissed me off really, as if I'd wanted to copy it I'd only need to send the cam to another manufacturer and it'd be job done. I wanted to know so I could try a few different cam profiles, as although it worked I wanted to experiment further.
Note that ze Germans seem to use a Schrick cam, which depending on the Newman specs, I was going to give a try.
-
I can get hold of Schrick cams for about £215 delivered if there's more than 5 people wanting them (a few on Club polo want them at this moment in time).
I can also get the part numbers off my Newman cam and give them a ring about it.
I'd be very very very wary of giving Steve Pitt any money at all guys. (Read Eekie's thread on Club Polo)
-
yea if you can give newman a ring yoof that'll be spot on!
i like the idea of a schrick but i think thats a bit expencive,
surely newman want to sell some cams!!!
i find alot to do with G40's secretive and seems to be everything you buy for them is over priced
and you wait a stupid amount of time for something to be deliverd!

Have you got a link to that Pete?
Agree with Lance, get a part number from your cam and give Newman a call would be great Pete.
Thanks in advance,
Richard.

i have an eaton spec cam i could really do with the setting up info for it if anyone can help me out
-
Pretty much got my mind set on turboing my G now.. Find chargers to be too tempremental..
Gonna start gathering parts for the conversion.. This thread has been very usefull guys..
-
Agreed, this has been a very helpful thread. Especially regarding the camshafts required for going turbo. Was going to put mine on with a standard G40 cam, however I’m thinking of delaying fitment now.
***If there's a group buy going to happen for either a Newman / Schrick turbo specific camshaft then I'm interested.***
Dubpolishers: If you're after buying it all in one shot.. you can from here: http://www.emtec-racing.de/Turbokits.htm
€1550 is on the steep side considering you can put a kit together for <£800 by using some 2nd hand parts, but I thought it was worth it as it’s top notch quality and includes all oil & water lines, hoses, brackets, clips etc. It all adds up!
LregG has the manifold on his beige beast and looked might impressive. Looks even better in the metal :D Mine came with a KKK K03 turbo + plate to fit to their equal length manifold & I had an up-rated fuel pump too. Looks like they’ve canned the KKK K03 option now, as was about €70 more & the plate to fit it to the manifold was €20. Will get some pics taken & posted up.
PS. Off topic, but check out their Audi S2 (5cyl) manifold… work of art!!
PPS. what do you guys make of this: http://www.bar-tek-tuning.de/lshop,showdetail,2004g,e,1234956743-1614,1169360067.1204708405,2140058,,Tshowrub--1169360067.1204708405,.htm

-
can you buy the manifold and downpipe anywhere from that kit?
fancy fitting a garret to mine one day.

-
you can get the manifold for €400, but think the down pipe is part of the kit only.
By all means email them to check though.
-
check philjs threads in the traders section on here. he can get manifolds and downpipes for a lot less than from rothe.
-
i already have my manifold and downpipe from rothe just in time id like to go garret gt25rs

Hi,
When you say you have put a G40 into a GTi do you mean the 6N2? if so how did you do it? was there many modifications to be made to engine mounts etc?
Thanks, Stu
-
Is the AAV camshaft better than PY in turbo'd G40??
what else cam can i use with my turbo project?
-
someone ?? ??? ??? ??? :'( :'( :'( :'(
-
I've not heard of anyone using an AAV cam, no idea what the specs it are. A GT cam is your best bet for one but not ideal. One of the proper turbo specific ones from Catcams, Newman or Schrick are best.
-
damn :( i found a specs :( thanks.. its useless with turbo convertion :(
