Icegeezer Posted April 22, 2008 Report Share Posted April 22, 2008 Hi AllI'v have been searching for some forged pistons but im not having that much luck at the min, iv got a couple of leads but rather me search every where, I thought I'd pose the question to people who have done internal engine mods or who knows there stuff.......Please no silly posts like have you tried halfords or motorsavers So far iv pulled a negative from quite a few of the UK's BIG tuning companies,anyone dealt with German companies who know they sell them? Remember, power is knoledge, so please share it lolThe Aplication Is a Lupo Gti 1.6 16vThanks all Quote Link to comment Share on other sites More sharing options...
Lee_ Posted April 23, 2008 Report Share Posted April 23, 2008 Someone posted these pictures in readers rides of some JE's they had had done for lupo.Might be of some help as the part numbers are visible. Quote Link to comment Share on other sites More sharing options...

Blackrat Posted April 23, 2008 Report Share Posted April 23, 2008 they will need to be custom made, you aint gonna find pistons that are just gonna fit straight in .. i doubt it£400-£600 for a set , you will need a dish to be cut in so you can rid that spacer plate, no point in getting high compression pistons and run a spacer plate IMO i would rather get a set of rods, cause if a piston breaks the damage is minimal, if a rod breaks you get a hokey pokey in the side of the engine block and a soup like metal substance in the sump :Syou got the pistons already, i say break them first (or try break them first) you dunno how strong they are .. imo ofcourse Quote Link to comment Share on other sites More sharing options...

veedubdude Posted April 23, 2008 Report Share Posted April 23, 2008 When I spoke to advanced autosport I was under the impression they're all available from suppliers in germany; however Ive heard a few stories about the length of time / bad customer service from advanced autosport so Im wary to place an order!

Tigzâ„¢ Posted April 23, 2008 Report Share Posted April 23, 2008 Thats what Erik told me also.Its not AAT thats the problem, its the suppliers in Germany who take their time.MK springs to mind! Quote Link to comment Share on other sites More sharing options...

veedubdude Posted April 25, 2008 Report Share Posted April 25, 2008 (edited) In the last few days, Ive found a guy who can get Pauter Rods, JE pistons, and custom crankshafts! JE pistons come in 4- 5 weeks with a price of £560 to the UK; rated to 650bhp! Pauter rods are around the £600 region, but take 6- 8 weeks, and custom crankshafts start at £1200 to £1500 depending on manufacturer.Let me just check the guys details and get back to you Edited April 25, 2008 by veedubdude Quote Link to comment Share on other sites More sharing options...
MrMischief Posted May 2, 2008 Report Share Posted May 2, 2008 (edited) Hey Not sure if this is completely applicable, but as you say - knowledge is power I've got JE forgies in my GT4, they came from Toyauto (now TR&D) in Nottingham. Fensport also deal in JE pistons & Ross so they may be able to get other specs of pistons from those suppliers that they distribute. Worth a phonecall IMO as they're priced around the £400 mark. With higher FI pressures, it's generally the pistons that go first due to DET, or the ringlands that'll burnout, rods only let go when the power/torque/revs get too high so it really depends on your application as to whether you'll need rods as well as pistons. Also, be prepared to increase the warmup/cool down time that forged pistons generally require - they expand much more than OE and generally will have the bores machined to a slightly larger tolerance to allow for this. While the engine is cold you may experience a little "piston slap", if you rev too much during this period you'll notice the oil level dropping until they expand.Good luck with your search... StevePS Be prepared for most insurance companies to dismiss you once you mention forged pistons. I'd recommend Sky Insurance, they do agreed value & like for like replacement parts schemes which are worth their weight in gold.

loopmuscle Posted August 27, 2009 Report Share Posted August 27, 2009 already tryed it m8 it not worth the price its 600 for the pistons and 1100 for the conrods just put a bigger engine init or turbo it. its more performance and its much cheaper Quote Link to comment Share on other sites More sharing options...
CasperGTI Posted August 27, 2009 Report Share Posted August 27, 2009 (edited) Woah digging one up from the past.I have JE forged box type slipper pistons (short skirt pistons). And Carillio Rods with CARR bolts With Total Seal Piston rings. Sounds hurrendous untill the car is warm with that set up. But the total seal rings keep the oil in the engine well during the warm up period.Because i have a slipper piston, i get alot more slap, This takes a good 10-15 mins to go at idle untill everything is nice and warm. Once warm, i get a tapping on gentile acceleration at 2000rpm, bu im told its nothing to worry about.Correct on the bores being machined differently, Forged pistons use a wall clearance of up to 0.004"I got mine in from Performance Unlimited in yorkshire. I dealt wth a bloke called Dave Powell, Top bloke and very helpful! Sadly with these engines everyting is custom made, Pistons take 4-6 weeks, Rods take 6-8 Weeks.Based on prices to import, and the pound to dollar being so poor, they will now cost in the region of £2000, mine were considerably less than that luckily.The pictures from this thread.... Those pistons were form a dodgy batch of pistons which are about as much use as a paper weight... there was a mess up on the machining process and the crown was machined too thin. I know that as i enquired about them when i had mine made, that was JE's respose.John Edited August 27, 2009 by CasperGTI Quote Link to comment Share on other sites More sharing options...
99hjhm Posted August 27, 2009 Report Share Posted August 27, 2009 Just for interest John...What was the issue you had with pistons... Is the rod end float controlled by the piston?Also, Is your engine std bore still? Quote Link to comment Share on other sites More sharing options...
CasperGTI Posted August 27, 2009 Report Share Posted August 27, 2009 Yeah the engine is still the std bore, I checked out each bore before i had the pistons made to make sure they werent worn. Dont know why i didnt go larger, but hey ho suppose i can when i rebuild it!!I had a preblem with JE originally with the pistons, they were made with the wrong piston pin boss width, and then with the wrong piston pin thickenss.In the GTi engine you have piston guided con rods... The gap is on the crank rather up at the piston. Quote Link to comment Share on other sites More sharing options...
veedubdude Posted August 30, 2009 Report Share Posted August 30, 2009 For those that want forged pistons off the shelf, they are now available from Wiseco. They have a crown cut-out to reduce the CR to 8:1 too! They're listed for the polo GTi engine ARC, which is the same as the lupo GTi, AVY.German eBay:Wiseco Forged Pistons Quote Link to comment Share on other sites More sharing options...

veedubdude Posted August 30, 2009 Report Share Posted August 30, 2009 My mistake then, sorry! I thought the two engines where pretty identical Quote Link to comment Share on other sites More sharing options...
CasperGTI Posted August 30, 2009 Report Share Posted August 30, 2009 Im not 100% but i think that was the case. Good find nether the less!, think i may look in to these more when i need an overbore!But still, it could work if you had a set of forged rods made to match the pistons pin boss width.And there about £100 less than JE ones.John Quote Link to comment Share on other sites More sharing options...
nfbr Posted August 30, 2009 Report Share Posted August 30, 2009 My mistake then, sorry! I thought the two engines where pretty identical Some of the differences are so petty, It almost seems pointless for VW have made a difference between them!
