The pistons i have for sale are 88mm dia Wossner, with a 1mm lower pin to crown height than stock, this means you can use a td or mi16 (1.9) 88mm crank (stock is 86mm) and standard rods (or after market rods with standard dimensions) to get 2139cc, no messing about matching pistons with different rods, having blocks decked, modifying pistons etc, just bolt together! (except having the bores taken to 88mm ofcourse)They are 11.5:1 compression using the 88mm crank, and have huge cut outs to safely run 'lairy' cams. I also have an 88mm head gasket to suit, im after £500 (+offers) for them. Im getting rid because i am back into racing motocross, and have 2 bikes to look after now. Speak to Sandy or Colin Satchell about a GSXR throttle body set up on their manifold, sandy has had some awesome results with them. |

I would say it would be worth changing the crank and rods if you are going to the extent of piston change. You could even go for the 2.1 td crank, which along with the 87mm pistons would make just shy of a 2.2. This setup with suitable cams + itb's is usually good for 200 lb ft! ________________________________________ 2.1 16v 306 Rallye. |

4 Injectors on the bell mouths or 8 as std give the best all round, Nice low down and a nice peak figure, on the 8v's you got about a 10% gain in peak power from this little mod.Sodemo are the only real experts on this engine in my mind, But you pay for it as you only have to look at the real BTCC cars (405 and 406) over here the engine's I remember always went pop but in Europe they won, I know budget had allot to do with it in the UK which never helped. But the overall engine spec really depends on budget and what you want from, High end screamer or a torque monster ________________________________________ 306 Rallye Sptint/Race Car, 205 CTI 1.9 8v to name a fewRoad, Track and Race/Rally car preparation to your personal requirements, Full Workshop & Diagnostic Facilities New and Second parts, from Plugs to Turbo's We now also carry out Routine Servicing www.pugracing.com & FB Page, https://www.facebook.com/PugRacing Ebay; http://stores.ebay.co.uk/Pug-Racing-Shop 2012/2013/2014/2019 Class Winners at Gurston Down Speed Hillclimb & Joint overall, Class record too along the way, |
