It Begins: The S3 1.8T into my '85 Mk2 GTI

[peedman]

Thanks for the replies guys, yeh im about finishing up on my abf but im dreaming another project , dunno what happened to not spending anymore money lol. Not many s3 wrecks come about, id doubt i would be able to find one as well thus the question about mods on a mk4 gti motor.

Btw golfballs, what gbox are u using aswell? The 6 speed (?02j) or an 02a??

[tommymac]

OK i'll def consider the 280's then cheers! Already running 15x7 BBS RS001's
Re: the qpeng. All upgrades are free if you use OEM parts. You just tell them what you're doing and they send a CD i think. Ben Leach is the guy there. I asked him to put some product info in with the package coz we're thinking of becoming Aussie qpeng stockists provided it turns out to be good stuff and the training and service is ok.
I'll see what spec info they've sent and put it up here for whoever is interested.
I wanted to use their kit coz i want to keep the stock ignition barrel, clocks, etc without too much stuffing about. Apparently their stuff is easy to install but time will reveal all!
Their version of the ECU already puts out a claimed 270bhp (up from the standard AMK's 210bhp) so further power is just excessive imo and will make the car too unwieldy and overpower the chassis. ~235whp is well enough I reckon! A massive part of good lap speed comes from how well you set up the suspension/chassis so hp upgrades aren't really on my mind.
Cheers

Mate i just finished wiring mine took one night and some wiring diagrams ( some colours vary) easy though so let me know if your starts first time! i am plumbing in my cooling system as we speak

[GOLFBALLS]

Awesome!
Re: the ECU, it's made by MBE.
Re: the S3 brakes, the fronts were alcons and sold em. Were too big for the wheels i want anyway. And i got the post '89 16v hubs (thanks aussieg60) with the removable carriers so i'll go the 280 disc.
Here's some pics it came today Well, actually the throttle body was broken but we have a spare here in better nick anyway..






As you can see, the downpipe is pretty well put together and is 2.5"
Just gotta get the LSD, and new vibra technics eng and g'box mounts, and find a way to fit and plumb the 'sprintercooler'

Na 02J from 16v Corrado (thanks roccodingo!!)
6 speed quattro box doesnt really go.

Going great guns - good work

Don't waste your money on the Vibratechnics engine mounts - I bought one for my Ibiza ages ago and promptly sold it to be replaced by a Turn2 kit... which did the same job for a fraction of the money.

That few hundred bucks can go towards better braking

[tommymac]

FYI

Wilwood sell a kit in the UK which are LEGAL in australia and DO have dust seals (making them legal)

i think its 400 UK all up for calipers discs and all hardware - the american kits are not legal is Australia (no dust seals) - retards

Girlings pop up every so often on ebay - bahnbrenner do a kit for 700 USD.

anyhow let us now what brakes you go with - as valver said piss off vibratechnics and just order heavy duty g60 mounts unless you want to die of vibration ( you can put the polys into the mounts if you like - sikalfex is also a good little trick to stiffen them up but not so stiff you have hemorrhoids

[aprr32]

I have AP calipers on the front of the Caddy with no dust seals,the engineer passed them and so did the ACT rego inspection.I can't see the problem.

[tommymac]

techincally there not legal. Just could mean that if your car was checked to a stupid level your insurance could say bye bye, likely no.. but hey i dont want that risk, guess it depends how modified your car the less stock it is the more they will inspect. Strange though AP are always passed cos there fkin awesome i thought they all had dust seals - meh i get confused some people say yes other no? fuk knows

[GOLFBALLS]

hmmm

Hey people. I dont know if anyone here has any experience with this, but there is some evidence in the K04 that there is some rubbing from the impeller/turbine on the casing. It's only minor and the car was obviously running ok like this. Any thoughts??

[h100vw]

Can you get it to rub now?

As I see it there's 2 ways to go.

Cheap way, ignore it and it'll go away, probably.

Expensive way, buy another/have that one refurbed.

I have come across jet motors that wouldn't turn at all due to heat expansion causing the blades to touch the sides of the engine.

Maybe a couple of hot shutdowns and restarts caused it.

[roccodingo]

Mmmmm...

take it to turbo tech and get them to check it out, maybe just need minor work to rectify it, but leave it and it has the possibility of causing major grief...

[GOLFBALLS]

mmm yea good point might do i think. It's not much of a scrape really and only on that one spot. There is about 0.5mm of play (side to side) if i really give it a firm wobble and then it just rubs on the side but still turns.
Sounds quite possible it could be the heat expansion thing as Gavin mentioned?
The foreman at Audi Centre Perth said some of these have lots of play in the turbine shaft. He's seen Q7 TDI turbo's with almost 1mm of movement in the turbine!! Well, i assume that's a lot anyway.
But this turbo business is pretty new to me still and i'm learnin as i go, so to be safe i'll get it checked by a specialist.
Thanks lads
I'll let ya'll know what the deal is as soon as i know!

[Valver.]

I wouldn't worry about that - I have two new Garretts here and both of them have a fraction of rubbing against the housing Once the wheel is at full speed, it'll centre itself and won't rub anyway.

[Golf Loon]

Yeah they have a fair bit of play when idle.

[gldgti]

once oil is forcing its way through the bearing case under pressure, it centers the shaft - one of the reasons you need a tip top oil system for a turbo engine.
