looking for 350bhp ish, but as it only weighs about 950kg with driver and the bigger 2.0 engine its going to be putting out more like 380bhp per tonne lol, thats more than some well known porsches etc________________________________________ 309 GTi6-T |

Ahh i get you.Interesting, wonder if could get away with a compression plate on my supercharged engine and use standard rods and pistons ? ________________________________________ Dimma + Gt35 turbo =Solid rear beam mounts £130 07889376885 Dan |

maybe, but gti6 pistons are slightly different to s16 pistons, theyre 1mm taller iirc. id not recommend it if going above 300bhp.________________________________________ 309 GTi6-T |

This looks an excellent project, nice work with the manifold. Its always nice to see people doing something a bit different/doing the work themselves.whats the advantage of running the j2te block over the j4rs? and what CR have you gone for, looks to be a fairly thick de-comp plate. al ________________________________________ www.bridgecraftmotorsport.co.uk |

How much was the de-comp plate if you dont mind me asking. cheers allan ________________________________________ www.bridgecraftmotorsport.co.uk |

Isn't that turbo manifold pretty close to the brake lines? Is it already a plan to re-route them?Looks smart, the fabrication work is always nice to see. ________________________________________ '99 1.8 XS - Sold'00 GTi6 - Killed by armco '01 Cabriolet 1.8 - Sold '96 Eunos Roadster 1.8 Import |

well the engine is coming out again at some point, but im not sure if ill be fitting them. my brother runs his 106 xsi (all speced up throttle bodies, cammed etc) without a cam cover, and thats used regularly on road and on track (sprints etc) and is fine. might do for reasurance though, also gives me something to paint  ________________________________________ 309 GTi6-T |

wastegate is still a no  stupid bonnet is in way, and head aswell lolthis is the most complete ive seen it since the gutting started about a year ago. got radiator in minus the fan, and then moved it back about an inch and slid it across towards the passenger headlight. This gave me the room the the intercooler piping to go past it as you can see (the blue pipe) and the intercooler fits infront of it, the other pipe will go down near where the horns are and then under the chassis and back up. i have about 65-70mm clearance between rad and intercooler, so anybody know of a slimline in that size?    ________________________________________ 309 GTi6-T |
