wardycatt 7 Posted February 9, 2012 Report Share Posted February 9, 2012 The words 'budget' and 'VRT' in the same sentence send shivers down my spine, but now I've done all the minor servicing and have started on the bodywork of my Mk3 Golf, I've got half an eye on forced induction at some point in 2012. My intention is NOT to set fastest times at Santa Pod or go drag racing, but to be on a par with some slightly beefier cars, such as a standard-spec Mk2 Focus ST (225bhp, 235lb/ft) or Mk5 Astra VXR (237bhp, 236 lb/ft). At the last check, my (fairly standard) car was putting out about 185bhp. I would like to maintain the car's reliability, but I'm on a very tight budget. Therefore, I am aiming for about 250-260bhp from a low-pressure setup. Other posts have suggested this is possible, that's where I've got this idea from. Here's my shopping list:Turbo (maybe a T30 or T35? - are these OTT? - any advice appreciated)ManifoldFuel management deviceSpacer gasketIntercoolerOil coolerPipework, hoses, clipsARP boltsChip / remapBOV...Anything obvious I'm missing?I wasn't sure if standard injectors would do the job - I've accounted for uprated ones anyway, just in case. Other 'maybe' items on the list are a heatshield 'nappy' thing for the turbo, although I'll probably need copious amounts of lagging regardless. I'm sure there's more. Other considerations are what should be replaced at the same time as this work's going on? I was thinking the timing chain and the clutch for starters, and the 312mm front brake conversion is a pre-requisite.I don't claim to know anything, so please correct me if I'm being stupid / misguided / delusional about this.

russj249 2 Posted February 9, 2012 Report Share Posted February 9, 2012 I know you've probably thought about this.. but for you're needs and wants, with good power, reliability etc etc it would probably be better and a hell of a lot cheaper going for a supercharger.I did a so called budget turbo myself, and it cost a help of a lot more than any supercharger sells for.. Also less need for engine work with charger, don't need intercooler or any major pipework, don't need manifolds, downpipes, exhausts etc, a raceland 6 branch would do perfectly, less moving parts so less to go wrong, and a nice smooth power delivery.I think charger for under 300 and turbo for over 300. Mainly because turbo will make more torque and power from the same amount of boost. Link to post Share on other sites
CALICO 130 Posted February 9, 2012 Report Share Posted February 9, 2012 I think they can be done for about the same sort of money but low pressure supercharger you wouldnt need to put a spacer plate in and shouldnt need an intercooler but BOOST is apparently addictive maybe you could try going in a supercharged and a turbo'd and see which sort of power delivery you prefer.

michael5556 247 Posted February 9, 2012 Report Share Posted February 9, 2012 I'm afraid I have to go with the above. I have a vrt and it's not cheap. Especially if you want reliability which means no Chinese eBay stuff. If your only aiming for 250, buy some cams and a charger. Much easier, more reliable and much easier to install.

Andi 0 Posted February 9, 2012 Report Share Posted February 9, 2012 Just to give you a idea, my stage 2 charger setup has cost me a little over £2000.If your only using 6psi on a turbo setup you prob wouldnt need to be intercooled or lower the compression. The Kinetic stage 1 turbo kit doesnt. Link to post Share on other sites

wardycatt 7 Posted February 9, 2012 Author Report Share Posted February 9, 2012 Thanks for the quick replies. All I want to do is give my standard VR6 a kick up the backside. If the supercharger is the easy-install, easy-maintenance option and it gives me in the region of 250bhp that's brilliant. But surely it can't be that simple, can it? One other thing - how does the fuel economy compare between the two? Link to post Share on other sites
craggsy 91 Posted February 9, 2012 Report Share Posted February 9, 2012 super charging is literally bolt charger on and get it mapped, with low PSI.To run more PSI then id get a spacer plate put in and possibly bigger injectors.I ran a rotrex with spacer plate, standard injectors and 6psi pulley and had 300bhp Link to post Share on other sites
Russ_vr6 12 Posted February 9, 2012 Report Share Posted February 9, 2012 Where is the best place to purchase a charger guys? IS it best going 2nd hand? Im assuming off here? Link to post Share on other sites
russj249 2 Posted February 9, 2012 Report Share Posted February 9, 2012 Where is the best place to purchase a charger guys? IS it best going 2nd hand? Im assuming off here?They come up now and again on here, also now and again on eBay.. can't go too wrong with a charger though, mainly because there's no cheap dodgy chinese copy superchargers. If you see a vr6 specific charger, chances are its a branded and well known make. Link to post Share on other sites
russj249 2 Posted February 9, 2012 Report Share Posted February 9, 2012 With a turbo 6 psi will NEVER be enough sorryYes I agree.. 15psi should legally be a minimum boost pressure for turbo's! Link to post Share on other sites
matty.vrt 120 Posted February 16, 2012 Report Share Posted February 16, 2012 And even that will only keep you entertained for a few months before you know it you will be at 25psi thinking hmm time for forged pistons and rods and more BOOOOST. Link to post Share on other sites
