I'm trying to make up a list of "off the shelf" pistons which fit, or can be made to fit the Swift 1.3/1.3.<br>If anyone can help I'd be grateful, I'm looking for:<br><br>Vehicle piston is from,<br>bore,<br>compression height (distance from the centre of the pin, to the top of the crown),<br>pin diameter,<br>piston height, <br>weight, (if possible)<br><br>I'd be very interested in info fromthe guy's who say they're using Gixer (GSXR) bike pistons, as my researches show they have a pin diameter of 18 or 20 mm,.The Swift uses 19mm. Also the nearest Gixer bore is 76mm, but those pistons have a compression height of only 25.5mm. The G16 is 28.5 whilst the G13 is 29.1.<br><br>Methinks the smell of bullshit is in the air somewhere.<br><br><br>Anyway if anyone can help, please mail me at<br><br>patersoniain@yahoo.com<br><br>Thanks.<br><br>Iain <p></p><i></i>

We looked at the bike pistons for mine but they didn't have grooves where we need them (oiling I think) we took to a VERY good machine shop and they wouldn't touch them. <p>Keep those RPM's high!www.lobase.homestead.com/lobase.html</p><i></i>

Yeh, I think there are a lot of people who don't have what they think they have, inside thier engines, certainly not what some of them have paid for.<br>I'm pretty pissed of by the whole thing, so i'm determined to find out what fits and what doesn't, without going to the trouble or expense of getting some made.<br><br>Heard anything about the "you can't fit 76mm pistons into a 1.3 'cos it's not safe" crap, I keep hearing it but everyone goes blank when you ask "safe How / Why ?".<br> <br>Iain <p></p><i></i>

aren't your running the cylinder wall a little thin with 76mm pistons? or is that just a rumour as well. Haven't actually taken any tools to the block to get some measurements, so I could also be talking out of my ass until I measure it. I agree that there definetely seems to be a lack of 'reliable' info out there and a lot of BS seems to be floating around. <br><br> For me, after a few races with people on the street having them ask me 'HOLY COW WHATS IN THAT THING".. and seeing as nobody really knows what the heck these cars anyway it becomes so very tempting to just start babbling about how I put a bike motor in it, or it's a VTEC, or it's a V6 or something stupid rather than telling them I run nitrous. Could be some people weren't just tempted like I have been, and started just making things up, so the info has been distorted along the way. But perhaps, on some levels, maybe not...<br><br>Is there really nobody out there on this board that's played around with alternative 'off-the-shelf' pistons?<br><br><br><br><br><br> <p><br><a href="http://www.teamswift.net"><img src="http://members.home.net/2832075173/pics/Swiftafter1c.jpg"></a></img><br>Kyle Jones <b>1989 Suzuki Swift GTi</b><br>Your friendly TeamSwift Op.</p><i></i>

I too got tired of hearing all the talk about using this or that piston without anyone every identifying exactly "which" piston and ended going the expensive forged piston route with 8.5:1 CR and 40 over at a cost of $500. <p></p><i></i>

HOW MANY TIMES YOU HAVE TO READ IT--------------;-)<br> "ESTEEM/VITARA 1.6LT PISTONS"<br><br>MY FIRST CAR WAS A SUZUKI ESTEEM 98 1.6LT SOHC AFTER A FEW MONTHS I HAD A MODIFIED CHRYSLER .48-.60 TURBO ON IT AT 18PSI A HALTECH MANAGEMENT SYSTEM AND A ELECTROMOTIVE HPB-1 IGNITION SYSTEM ALSO. I HAD NEVER, I REPEAT NEVER, EVER, HAD A PROBLEM WITH THAT ENGINE.........................AND BELEVE I'M ONE OF THOSE GUYS WHO GOES TO THE STREET RACES EVERY SATURDAY AND WENESDAY AND WE ARE TALKING HERE ABOUT ROYAL BEAT DOWN TO THE CAR, 8000 RPM SHIFTS (NO RPM LIMIT CAUSE OF THE HALTECH), AND STILL USED IT DAILY DRIVEN TO WORK AND TO STUDY, SO THATS WERE THE REAL B.S. IS ABOUT THOSE STUPID RUMORS ABOUT THE 1.6LT. KNOW I HAVE MY 94 SWIFT GT 1.3LT DOHC TURBO AND STILL HAVE MY ESTEEM CAUSE ITS KNOW MY ONLY DAILY DRIVEN CAR, RIGHT KNOW IT'S BACK TO STOCK, AND I'VE NOT OPEN THE ENGINE NEVER AND I BOUGHT THE CAR BRAND KNEW (SO ITS BEEN 3 YEARS). GOING BACK TO THE PISTONS ISSUE AS I SAID BEFORE I HAVE A SUZUKI SWIFT GT 1.3LT DOHC TURBO WITH A SET OF ESTEEM/VITARA 1.6LT PISTONS WITH SOME HARD RINGS AND BEARINGS (CLEVITTE 77).I RUN AT 30PSI AND I HAVE NEVER HAD ANY PROBLEM WITH THIS PISTONS AND FOR THE COST ($50 EACH, AT LEAST HERE ON P.R.) WHAT MORE COULD A GUY WANT????????<br>JEJEJEJEJE, TO SHOCK YOU MORE HERE ON P.R. WE HAVE HONDAS THAT I KNOW THAT RUN WITH THIS SAME PISTONS.....<br>BELEVE ME THERE'S NO OTHER CAR CHEAPER TO BUILT A GOOD PROYECT THAN A SWIFT. (AT LEAST ON P.R.)<br>SO QUIT COMPLAINING AND LETS START SHOWING THESE HONDAS WHAT A REAL CAR CAN DO.............;-) <p></p><i></i>

GSXR1100 pist9ons will fit the G13B with a slight overbore. Very strong pistons (from a motorbike) that have been built to withstand over 13,000 RPM. <p></p><i></i>

Would the pistons from a Sprint or firefly turbo fit? I mean same engine minus one cylinder right? Are they lower comppression pistons or did they just use a decompression plate? <p></p><i></i>

Zeus, <br>which pistons ?, which model of Bike ?, the nearest to the swift bore I can find as standard are the Gixer 11 at 76 mm bore but they only have a comp height of 25.5 as opposed to the 1.3 of 29.1 or the 1.6 at 28.5<br>Iain <p></p><i></i>

we checked them all when I was looking for pistons and none of them worked. <p>Keep those RPM's high!www.lobase.homestead.com/lobase.html</p><i></i>

You're right Tony, If I never see another piston catalogue it'll be too soon.<br>Did you have to re-chip when you fited the 1.6 pistons ? and, did you use the standard or overbore size ?<br>thanks <br><br>Iain <p></p><i></i>

we did not re-chip. I had the block bored to 75mm and shaved to increase compression, the head was also shaved to match perfect and to increase compression. Fred (my mechanic) said it is now running at around 11:1. I find with the mods I have done my biggest improvement is torque. <!--EZCODE EMOTICON START :) --><img src=http://www.ezboard.com/intl/aenglish/images/emoticons/smile.gif ALT=":)"><!--EZCODE EMOTICON END--> <p>Keep those RPM's high!www.lobase.homestead.com/lobase.html</p><i></i>

Hi Iain,<br> I have got an article here that has some info on pistons used in a race swift.I can only tell you what is in the article soyou would have to check out its validity!.<br> Wiseco piston for a 1983 Honda xr250 matched with xg rings.(very thin rings)<br> Gudgeon pin is 19mm std GTI<br> Piston skirt requires about 7mm to be removed.<br> Piston crown has to be flycut for valve clearance.<br>This engine used the cast crank which has a longer stroke than the GTI crank?? then the block was decked to bring up compression to12:1 by removing 3mm???<br> Std gti con rods were used with fully floating gudgeon pins held by circlips.<br>More info from Suzuki auto centre (AUS code+82319344)<br>If you want I will give them a call,if it sounds like trhe sort of piston your chaseing.<br> Cheers Dave <p></p><i></i>

To PRGTI,<br><br>I have also turboed my GTi, but am running only 7PSI of boost off a T25 garrett because I am using a Cultus G13B which has high compression (11.5:1). You have said that a cheep alternative is for me to swap pistons to the G16B or G16A piston. Is it a straight swap or is any machining of the pistons or bore required? What compression ratio can be expected? I am hoping for around 8.5:1 so I can then wind up the boost to 15PSI and start making some real horsepower....<br><br>Thanks <p></p><i></i>

You need to overbore, the G16 piston has a lower compression height, the larger bore also allows you to modify the head for better flow, this also lowers the compression ratio further.<br><br>Iain <p></p><i></i>

You'll need to bore the G13 block to 75mm ( .040" over). The compression ratio will drop to about 8.5:1 <p></p><i></i>
