1990 Yamaha Fzr/blade Turbo

What’s the story? Had the FZR400 frame kick­ing about, so de­cided to stick a ’98 CBR919 Fire­blade mo­tor in it. It’s a tight fit! I ini­tially ran the bike on carbs, rode it for 30 miles then re­alised it needed a turbo.

Progress so far? Daniel Le­an­der in Swe­den talked me through what needed do­ing via email. I got a Saab TD04HL turbo, made my own stain­less man­i­fold, pipe and plenum cham­ber. I adapted a BMW S1000RR swingarm to fit – 100mm longer than stan­dard to help keep the front down! I’ve up­rated the mo­tor with studs rather than bolts for the head, a steel spacer to lower com­pres­sion, a slightly longer cam chain and al­tered cam tim­ing.

What’s next? I started the con­ver­sion do­ing odd bits at week­ends so progress is slow. Even though ev­ery­thing is tight with the FZR frame and CBR mo­tor I’ve still man­aged to keep the orig­i­nal fair­ing. I reckon 200bhp when it’s done. It should be, er... ex­cit­ing.
