    I have been applying subtle tweaks to my S3 since I bought it back in October 2008.

    I have not made a big thing about my tweaks as I like the sleeper appeal of a car looking pretty standard hiding all sorts of untold silly nonsense...

    Mods to date are Bilstein B8's/30mm Apex springs, AH Fabrications FMIC, DS2500's and Motul RBF600, silicone hoses and the normal Green panel filter and Forge DV upgrade. All topped off with a Custom Code stage 1 map.

    I have been after a turbo conversion of sorts for a little while now as everything is more or less in place ready for this next step. I have spent a bit of time over at Badger Bill's and have seen Matt20vt's big turbo A3 become a reality (and I have also been out in this very fast machine too), various SEAT Ibiza's and Leon's with all sorts of tuning goodies thrown at them (you SEAT boys aren't shy) and more recently barnsley's VW Polo with a GT30!!!, I wasn't convinced I wanted the agro of going BT and just thought I go K04 hybrid and 3" downpipe as I like the idea of the engine bay retaining its OEM look. However..... after another trip to see my good friend Badger Bill last week, its almost as if he has been reading my mind as setup on his spare engine when I walked in was....

    ...an underslung GT3071R with a an 0.62 hotside (PAG Parts mani).... Yes, you've guessed it... this is now destined for my car

    My car is over at Bill's towards the end of this week as he has kindly allowed me to work on the car at his workshop under his expert eye.

    Here are a few more pics of goodies lined up ready to go on...

    Not at this point in time mate no. I wanted to build a 2ltr stroker originally but I am building this on a bit of a budget to see what I can actually get for the money.

    Its easy just to throw cash at a project like this but ultimately the end game is to get a drivable car that is reliable and has power. Main reasons for head work and valve gear is more top end power or to allow the engine to rev higher reliably if the power curve keeps on going. There have been occasions where people have spent a small fortune on engine rebuilds only to find their chosen turbo and other parts means it doesn't give power much beyond the factory redline. I want to see what the result is using the components I am using then if it looks like I will get appreciable return for replacing the valve gear then I will do so.

    Agreed uprated valve gear gives better reliability of the engine but tbh not at the current expense of doing it. Not at this time any hoo. I am keeping it smallport as I spend a lot of my time in the car driving across town on the rat run, I have owed 'hotrods' in the past and they are just a complete arse to deal with on a daily basis..

    Not cheap this tuning lark but just trying to apply a logical upgrade path to keep the costs down but still get the result.

    Polo is looking good though ;P

    Can vouch for that mate... its well snug in there and a lot of engineering issues to overcome and keep the car safe to drive... Can't just throw these things together... although I have seen it done :hide:

    We planned this build through looking at a sensible approach to it and sensible components. I was going to go GT2871R but Bill had the GT30 in and I was sold... It suited what I wanted for the car and I have tried not to go OTT with the spend.

    That said, clutch is next on the list :(

    They are AP Racing calipers but couldn't say if they are the same as the Ibiza. I got them from ebay for £325 brand new..

    http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=250455042455

    Bill is getting brackets made so they will support 323x28 cupra discs as well as the 330mm 2 piece jobs he does...

    Once he has the brackets in, I will offer them up and chuck up some pics.

    Highly interested in this build as this is what im planning on doing to my lcr. What figures you hopping for and you got a shopping list of mods that you are buying or bought for the engine?

    The plan is to be fairly conservative using around 1.4bar (if you can call that conservative) so expectations are late 300's maybe 400bhp?? dunno... not so fussed about the ultimate power just that its all running nicely as its a daily driver.

    Shopping list/spec wise...
    PAG Parts log mani
    PAG Parts GT3071R with .62 hotside internally gated
    Integrated Engineering Rods (OEM shells)
    OEM headgasket
    Badger 5 Phenolic insulator
    Siemens Deka 630cc injectors and rail spacers
    355lph inline fuel pump
    AH Fabrications S3 FMIC
    Forge DV
    Silicone hoses all round
    Custom TIP (fabbed by Badger 5)
    3" downpipe (fabbed by Badger 5)
    Custom (something) to connect the comp outlet to the S3 OEM charge pipe
    Badger 5 Stage 3 mapping
    THS engine mounts
    Green Panel filter in modded OEM airbox

    Thats about it for now...

    I do have a custom exhaust system lined up which will happen after the build (3" SS) and I'll wait for the clutch to go before I deal with that as I need to sort my third gear out... its a little 'stubborn' at time :)

    so apart from the the rods your not doing anything to the block or pistons etc. Would you not achieve anything from a stroker kit at all?

    I am not doing anything else at the moment as all the signs suggest the engine is in good order. I am undecided on the stroker as I don't know if I will get enough return for the outlay (I am a tight arse). I want to see how spool is on the 1.8 and where the power curve ends up before I decide on how to rebuild the engine. 2lt will give better spool, more base power and a bit more power top end but will be around 700 quid more than just pistons and an over bore. I may just overbore to 1.9 instead as the difference in power prob isn't really worth the extra.

    When I know what the current setup is capable of, I will decide what to do about the full rebuild.

    Hi Paul,
    Will be keeping on eye on how this turbo spools - nice test bed to see if it's going to be suitable for my golf up there :help:

    Just had the OK from THS to mention that until the end of September, if you go and buy the complete set of mounts from their site (http://www.thsperformance.co.uk/product/FR3_Full_Engine_Mounting_System_THSFR3-CMP) and use the following code in the basket (SCNFR3CMP) it will give you £69 off the £199 retail price.

    There is a £13 delivery charge so this lot cost me £143 in total... bargain :)

    the calipers take the same pads as the mk4 ibiza cupra, but are radial mount not lug mounted stylee.
    brkts in progress to accomodate 323x28 one piece and 330x28 2-piece in 5x100 fitment.
