XR2i Rallysprint Car

Postby Bobson on Wed Jan 16, 2019 10:11 am

Hi everyone,
My name is Andrzej (Andrew) and I'm from Poland.

I have been using Fiesta XR2i 1990 for 6 years. The car serves me as a rally car and has undergone a number of modifications since then.
I would like to describe and present the final modifications and my idea for XR2i Rallysprint by Bobson :)
The general assumption is to start in rallies and rallysprints in the class up to 2000cm3 capacity. The goal is ~ 900kg weight and 200PS + N/A

Engine:
- 2.0 NGA
- Pipercams 285H, OBP Vernier Pulleys
- Inlet valves + 1mm (in plans) and full machining of the head
- ITB based on GSXR1300 trumpets + Saab Turbo injectors
- forged pistons Wossner 12:1 and forged connecting rods
- balanced crankshaft, suppressed flywheel (from 8.6kg to 4.2kg)
- baffles in an oil sump, 13 rows oil cooler with thermostat
- polyurethane engine mounts
- dedicated (according to calculations) exhaust manifold and the rest of the exhaust (in plans)
- EasyEcu 3+ standalone computer with a multifunction display

Transmission:
- Fiesta MK6 TDCi housing
- Torsen Val Racing 50% 10Kg
- hybrid gears and main gear ratio 200km/h@7500rpm
- 4-blade sinter clutch
- Vibratechnix box mounts

Braking system:
- rally pedalbox with adjustable braking force distribution front/rear
- front discs 280mm ST150 or 300mm ST170 (under 15 "rim)
- Focus MK1 rear discs, braking force corrector
- hydraulic handbrake

Body:
- XR2i package, RST bonnet
- extended safety cage according to Annex J
- bucket seats, seats mounts for the floor in accordance with Annex J

Suspenion:
- Gaz Gold coilover kit
- Powerflex Black Series bushings
- RS Turbo ball joints
- power steering 2.8 with electrohydraulic pump
- Fiesta MK5 rear beam with two anti roll bars
