gazbrook 0 Posted April 11, 2004 Report Share Posted April 11, 2004 Hi guys , like i have said before my car is almost finished with the 3 litre conversion, i am having new pistons in my car and there is a choice of 2 , one set for normally aspirated and one for forced ie supercharger or turbo, i am pretty sure that i have the pistons for a NA car not the forced induction ones, what is the difference?? Will i melt my pistons if i put a charger on my car??? I'm pretty sure they have been fitted already so i can't change the pistons i have , HELLLPPP Link to post Share on other sites
ingham 5 Posted April 12, 2004 Report Share Posted April 12, 2004 it all depends on what pressure sc / turbo u use. Link to post Share on other sites
Guest Olly_K Posted April 12, 2004 Report Share Posted April 12, 2004 gazbrook, where you getting the 3l conversion done ?i can i ask how much ?churs Link to post Share on other sites
gazbrook 0 Posted April 12, 2004 Author Report Share Posted April 12, 2004 So could i get away with a low pressure charger?? Maybe about 8 psi!! Is that low pressure for a supercharger?? Even if it gives me 30 or 40 bhp extra insted of the usual 75 bhp a charger gives i will be well happy. Link to post Share on other sites
mightyvr6 0 Posted April 12, 2004 Report Share Posted April 12, 2004 8 psi is fine for an engine with standard compression. My 6 psi gives 80+ hp and 8 psi with injectors will give 100 hp increase. Link to post Share on other sites
gazbrook 0 Posted April 12, 2004 Author Report Share Posted April 12, 2004 I want to get the most power possible but be careful i don't knacker my standard compression pistons, i might just go with 6 psi if that gives 80 bhp,just to be on the safe side !! Thats more than enough,that should take my car well over the 300 bhp barrier, just need to fit wings and it will fly!! Thanks for the advice guys , any more opinions and advice is welcomed!!

mina 0 Posted April 12, 2004 Report Share Posted April 12, 2004 From my experience 8psi does not equal 100 bhp. You might get 70-80bhp with injectors and an 8psi wheel. Standard pistons will be fine - you just need to run a copper head gasket and stronger headbolts. With a 3 litre head - you should see at least 250 to 260lbft of torque - that's your real target. Forget about bhp - it's torque that matters - ask any Honda Type R driver! Link to post Share on other sites
VRmonster 1 Posted April 12, 2004 Report Share Posted April 12, 2004 ye, agree with mina there, torque is the track daddy. bhp is just the pub equivalent. like a pub conversion of torque. 250lbft of torque on the track = 350bhp in the pub. (700bhp if you have go faster stripes and watch fast and the furious twice a week) Link to post Share on other sites
mightyvr6 0 Posted April 12, 2004 Report Share Posted April 12, 2004 I get 84hp more on 6 psi so I'd hope to be producing more than that on 8 psi + larger injectors.Vf-Eng quote 290 hp for their 8 psi kit (on the 2.9)which is 100 hp more. Link to post Share on other sites
gazbrook 0 Posted April 13, 2004 Author Report Share Posted April 13, 2004 I will wait till i get the money through from the sale of my house before i can pay for the charger conversion,no i'm not selling my house to get a charger!!(it wud be a crap house for that money) i will let you know what my car does before and after the supercharger conv, if torque is what matters performance wise then i want lots of it, my mate has an mr2 turbo, mine is as fast 2nd gear upwards but i just can't keep up on acceleration from a standing start, hopefully i will be able to beat his" jap crap" once i have done the mods,i would post a pic of my car but , A i don't have it at the moment and B it looks so standard its untrue!! So whoever is going to inters next month look out for me, i'm driving a standard looking black vr6 with black wheels and an england badge on the reg plate, cu there! Link to post Share on other sites
madmonkee 0 Posted April 13, 2004 Report Share Posted April 13, 2004 you get the 3ltr conversion from stealth? How much for everything m8ty let me know? I was looking at buying and importing a 3.2ltr from EIP tuning thats about £2500 just for engine, let alone fitting and everything.... Link to post Share on other sites
ukdub 0 Posted April 13, 2004 Report Share Posted April 13, 2004 awesome gti in warrington do the 3ltr for £3100 drive in drive away. That is a complete rebuit engine including chains, pumps and cylinder head Link to post Share on other sites
madmonkee 0 Posted April 13, 2004 Report Share Posted April 13, 2004 interesting... uprated pistons, rings etc?? Link to post Share on other sites
gazbrook 0 Posted April 16, 2004 Author Report Share Posted April 16, 2004 yeah new pistons and rings, the pistons are forged and abigger size too to fit in with the capacity increase Link to post Share on other sites
acf8181 0 Posted April 16, 2004 Report Share Posted April 16, 2004 is it really worth it tho? whats the gains?wouldn't it be better to get a 6 speed conversion with custom ratios and an atb or lsd, and a schrik? Link to post Share on other sites
gazbrook 0 Posted April 17, 2004 Author Report Share Posted April 17, 2004 well i have been told that the gains vary from 240-260 bhp as i have a chip,full stainless exhaust and induction kit too, but one of the main reasons i am doing it is so i can start of with a near new engine to put a supercharger on rather than putting it on an engine with 93,000 miles on that wouldn't last long the way i drive !!! As i was getting it rebuilt anyway i thought i might aswell get the displacement increased too, i wanted a quaife lsd at the time but i have spent every spare penny on the engine :-( a 6 speed box is next on the list when my gearbox blows up, so in effect i am going to "EVENTUALLY" get all of that work done too, fancy lending me a few grand anyone??? &| Link to post Share on other sites

Eat this 2 Posted July 2, 2004 Report Share Posted July 2, 2004 what about an r32 conversion anybody done 1/heard of 1 in a mk3??? Link to post Share on other sites
Guest vwsyncro Posted July 8, 2004 Report Share Posted July 8, 2004 Ive seen a eaton supercharger for sale is that any good , does anybody have experience whit this brand?be carefull with normal pistons , ive heard of people who have know 6 great ashtray's with hole's melted into them &| so use the low pressure , dont know psi , overhere it is about 0.5 bar, that would be good for 275bhp.there are r32 engines for sale on www.ebay.de , price around 5000 euro, think that is better then a eip tuning engine, would an engine like that run overhere in europe ?! dont we have different fuel overhere?

MarkGolf 6 Posted July 8, 2004 Report Share Posted July 8, 2004 What's this abouthttp://www.hiflowheads.co.uk/rebuilds/rebuilds.asp?car=vr6I asked the guy there, he said for the oversize pistons, plus a rebore to give near enuff 3000cc, your looking at around £800 which I thought was good...Seems VERY VERY cheap? Link to post Share on other sites
gazbrook 0 Posted July 8, 2004 Author Report Share Posted July 8, 2004 £800 for a 3 litre!!! That can't be right surely, if it is go for it, my conversion also had new piston rings,valves ,lifters,timing chain and tensioner,oil and fuel pump,clutch and loads of other bits and bobs basically making it new from the inside,as for the R32 conversion I have been offered a supercharged one for £5000 fitted in exchange for my engine too(this was valuing my engine at £2000) so £7000 all in all, its not really worth it for me tho as i have spent a fortune already on this engine and have r32 power,yes i know it sounds good saying i have an r32 conversion but its not worth throwing money away,or is it???

dubloke 4 Posted July 16, 2004 Report Share Posted July 16, 2004 i had a 3.1 conversion put in mine using a 'rado block and boring/stroking it to achieve the capacity! my engine cost over 4k including schrick 276 cams and a pp head, large tb, flowed(honed&extruded) inlet, flowed zorst mani, and induction zorst and remap! engine alone should produce in the region of 220-240bhp (260 is very ambitious), mine when it was run in and re-mapped was turning in 276bhp and 249lbs/ft. until it dropped a valve before xmas last year! must admit, for the money spent i wish i'd have charged it to start with and achieved the same result for less!

VRmonster 1 Posted July 16, 2004 Report Share Posted July 16, 2004 i wanted to go for new pistons to drop the compression before forced induction, but looking at i would have to get the engine bored to 2.9 in any case, as i have the original golf engine. so i may just go for a daft metal head gasket. lol.
