Is that for the "eco" version, not the veloce?

its from 1.6 88kW version... ECO version has longer Final drive...3,563:1 I think

did you make or buy the header on this car

its only polished standart exhaust header... with enlarged secondary pipes to 50mm ID

small update of this topic -I didn´t have much time due to the work..so I utilise every free minite last week...and worked on coupe...
- I´ve focused for increasing the reliability so I´ve installed a aluminium 16VT engine mout+16VT oil cooler in standart place (with generous ducting and fan which works together with water -cooler fan)
to keep the oil cooler
If its cool down 140kW+ turbo engine, it should be good for NA engine... and it seems it is..

During the roud tests in theese hot days (36°C air temperature...)the oil kept "cool" under 90°C...

Next step what I did -fitting of 25mm cambelt, adjustable pullyes etc, showed on the earlier pagefew years ago...

I´ve also to decide to time the cams to different values and I think it was good step: from 106/107 to 112/109 (serial tipo 102kW cams) and the engine is more "user friendly" at the streets, and tight curves... it now pulls wery strongly from 2000rpm even on 4th gear, which was with previous setting impossible on 3rd gear... however the strong peak at 5000 dissapeard, (whif feels extremely fast) I think that now the car is faster...

The RR sessiong with further remapping will show...
