aidy.t, what speed gearbox do you have?

Standard 6 speed box and a standard clutch at the moment! Looking to replace clutch soon and poss add an LSD. :D
Surprisingly the standard clutch is coping ok with all that extra power, no slippage yet under load, but probably not for too long.

lol i was going to say! spinning so much in 3rd that is slows the acceleration down on a 5speed means you are running some serious power/torque!!!

but 6 speed sounds about right.

ya the std clutch is been good for me also never slipped. but for the hell of it im going to upgrade to a spec stage 2 clutch, pelequin diff, bore to 83mm (1.9) port and polish, uprated intake and exhaust valves, rods and few other bits.

going to get it all done this month i hope, so should be a fun result!

:funk:

its all in the right foot.
for the first few weeks i kept the boost down.. i admit i was a bit nervous of the power. tourque steered alot which can be a bit white knuckle in rush hour.

but you adapt. now the boost is rarely turned down. you just get used to the power and your foot learns how hard to push. all hell breaks loose at 4k so shes fine driving around town.

im tempted to get the ihi conversion , but i know as soon as i get that im going to want more power, is it worth the 4k , and whats the most u can achieve when u get the internals uprated???

It is worth the 4k if you can justify spending that sort of money. But it is in a different league to a mapped LCR. You will not be dissapointed!. Im going for the internals next so it is a piece of mind that everything is up to the job, as well as getting the full potential of what the VF34.20 can acheive. Im hoping for around 370bhp? and the same torque figure. The car has already acheived 368lbft but mike pegged it back to around 350 ish lbft cos of the standard internals. But it is very quick! :D

other potential options being TD05-18g and 20g flavours

trouble with JS mani is space for larger turbo's & compressors in particular as its well tight down there, and there are several compromises in intake path due to its low position, 6spd box even worse being bigger and right in the way of where you want your inlet pipe. (gear cables, bell housing etc)

The GT30 Owens version being trialed is a potential upgrade, *(if) it can be made to fit without the compromises mentioned, and can clear the block/head castings.

Considering the boost you're running, aren't you worried about the bearings on the IHI? It's the one thing that is known to fail if pushed too far and I don't plan to go past 1.5bar on my conversion......

Test drive an S3 (stick to a 225 for a fair test!) and see what you think of the way it drives, the high spec etc and weigh up the cost saving over an STi. Should give you scope for what you could achieve for your money. I was looking at Scoobies when I came across my S3. The fact that I do a fair few miles per year meant that I preferred the 6 speed box and cruise control of the Audi. And it's screwed together well. The popular Jap 4wd brigade (you know who they are!) seem to be quite weak on the interior stake, IMO. I just can't wait to BT mine, I'm sure it'll be scaring more expensive machinery!

I wont be running mine on full boost all the time (only when needs must) so im not too concerned as i have Jabba's adjustable boost control.
Songmans LCR seems very reliable and his is running around 1.7bar of boost! I know he had a problem with the turbo but that was down to a faulty dump valve.

If your doing internals you want more power than you have. You need useable power I still feel in a road going Ibiza anymore than 425bhp is going to be a waste of time and about 460bhp in a Leon. Lag vs power vs useable power band. This is not a dig at Bills figures because the sound of over 500bhp in an Ibiza makes me smile but how it lays that power down in 2-3rd is hard to understand. I used my car last night and in 2nd it was spinning the wheels and a little in 3rd. Now add even another 80bhp to what I have coming in harder, traction must be a problem. Then consider adding another 160bhp on top of what I have like Bill and the mind boggles. I know the only way you can comment on these things is when you have done them so over 500bhp may well be okay. But I have seen 4wd scoobs/cossies/ Evo's struggle for traction with 500-550bhp now imagine an Ibiza (lighter) and 2wd. Bills torque is capped back lower than the cars above more than likely so that maybe the answer. So for a general daily driver maybe what you have in the power stakes is where you need to be would doing the internals and having another 10-20lbs ft and another 10bhp be worth the outlay.

Aidy... Thats a good point above:)

You are capped where you are now with the turbo, maybe another 10-15bhp/lbft on top of what you have now but with the additional risk of the turbo going pop with running too much boost.

I know songmans is running fine, but there are far more instances when they have not. Bill offers good advice and Wilko's been through a couple of turbos also.

In this instance i personally dont think uprating internals is worth the outlay for such a small further gain. It would give you peace of mind, but its expensive to do so. A further 2k on top of what you've already spent.

Here's an idea;).........Uprate the rods, and stick 100bhp nitrous through it. You would then have around 470bhp/500lbft of torque and be pushing the heels of Bill's motor:) Bills car sub 400lbft although higher bhp and lower weight. Would be interesting;)

Its cheating a little bit and i dont know if you want to go down that route but it would then justify the costs IMO:)

Anyway good luck with it buddy:)

Madmile and yourself Mitchy have a very good point.
Maybe NOS is the way to go. :think:

Mr Caney runs nitrous with his vf34/20 and posts 415bhp - he is very quick on the strip!!

In general it`s safe to say that power costs money to `do it right` - however it costs more money to do it wrong` cause you`re always rebuilding/replacing the broken bits!

Nothing lasts for ever! - especially when you are trying to run a `cooking `motor at 200+ bhp/litre!! - power output figures that a few years ago were only achieved in top echelon motor sport!
Believe me - we`re very lucky as enthusiasts to have such an able motor as the 1.8T to play with - thanks Mr VAG!

I did the rods/ valves not because I wanted the potential for more power, but rather because I wanted to ensure that I could safely use what I have - the idea being to `over engineer` with a view to safety and reliability, much in the same way as the original design concept of the basic engine.

Experience shows that what starts out at 1.6 bar may in time be 1.8+bar! - which is heading for 400lbs/ft - caveat emptor!:)

Maybe not though. If your doing internal work at least upgrade the turbo to the 400-450 mark. After that point I cant see 2wd being any use. Enjoy what you have for now and make a decission 12-18 months down the line. Running stage 3 in a little ibiza compared to the Leon helps me as I can imagine how the extra weight or even 4wd/weight of a S3 can dampen the speed/power sensation. Its like me having the car 4 up and it makes a big diff.
