Peugeot 106 Tuning Guide

The 106 has an amazing chassis and a solid engine. Quality 106 tuning parts can eliminate some of the compromises made by Peugeot and make the car even better.

The base car.

Lower rank models in the 106 lineup have many suspension, engine and shell differences from the performance models so they are simply not worth starting with unless of course you are considering completely rebuilding the car.

Peugeot 106 Tuning – Suspension

First step should be to renew worn out suspension bushes. All the big names make replacement bushes for the 106 including Polybush, Powerflex and Peugeot Sport.

Next step is to uprate the springs and dampers.

Bilstein have a very good reputation on these cars but there are companies making adjustable suspension kits like Spax.

If you want a fit and forget solution Bilstein is arguably the best choice, if you want a bit more flexibility then Spax is a good choice.

The rear suspension uses a torsion beam. The bearings on the trailing arms can wear out leading to skittish handling. Beams can either be rebuilt or there you can buy used from a Peugeot breakers.

The standard torsion bars have a diameter of 19mm on the Rallye and the GTI but common upgrades are 21, 22 and 23mm diameters. Upgraded bars cost around 350GBP.

Changing the rear anti roll bars can have a big effect on the handling. A stiffer rear anti roll bar will make the car more willing to turn in.

The biggest standard anti roll bars were 24mm in diameter and these were fitted to the 106GTI and S2 Rallye. Saxos generally used smaller rear anti roll bars.

The only way to be sure what diameter bar your car has, is to measure the diameter with a vernier.

Brand new from a dealer, the 24mm bars are only 85GBP and there are manufacturers that make even thicker ones.

As with all cars, the 106 benefits massively from strut bars and specifically front lower bars. Many companies make front lower bars for the 106 including Wiechers Sport, OMP and Sparco.

For the ultimate in chassis stiffness a roll cage is the answer and all roll cage manufacturers have something for the 106 including OMP, Sparco, Wiechers Sport and Safety Devices.

The best bang for the buck is to fit a 16valve engine from the GTI. This has 120bhp out of the box.

It is also possible to fit the newer TU5JP4 16valve motors from the 206, C2 nd 307s but you will need to redrill the head to fit the inlet manifold from the TU5J4 engine due to the fly be wire setup on the new engine.

For exhaust systems, Scorpion do a Group N spec cat back plus decat for 240GBP.

Headers are 10 a penny and can be had for around 150GBP. Intakes can be made up with a universal filter from K&N, Pipercross, Green etc.

The 106 exhaust can be fitted to the Saxo but it needs a bit of adjustment with the hangers.

Filter and exhaust mods can give around 130-140bhp, on the 8v around 110-120bhp.

Cams, loads of choice here, cost is around 300-400GBP.

Cams can take the 16v up to 160bhp.

Cylinder head. Shenpar, QEP and GMC Motorsport all offer high flow cylinder heads.

Engines also respond well to throttle bodies.

For best bang for buck, is forced induction, while space is tight there are many 106s with turbos on the road. DP Engineering look to be the specialists in this area.

For maximum madness, Z-Cars can fit a space frame in the rear equipped with a bike engine.

106 Tuning Guide – Brake Upgrades

As with all cars, the 106 benefits from fresh brake fluid and stainless braided brake hoses.

If you are lookin got increase the diameter of the discs then you have ppletny of choice.

266mm brake setups from 206GTIs & HDIs, 306s S16, XSI, D Turbo, HDI, Xsara VTR 1800cc and Partner vans will bolt onto the 106.

Expect to pay around 50-150 from your local breakers for the caliper, brackets, discs and pads. You will need 14inch wheels for these to fit.

283mm brakes from the 306 GTI6 and Xsara VTS will also bolt on and you will need a minimum of 15inch wheels.

If you want a brand name, HiSpec and Tarox make big brake kits for the 106.

106 Tuning Guide – Transmission

The MA series gearboxes have a reputation for being weak. The diff being the weakest point. Quaife, Tran-X offer limited slip diffs to replace the standard item.

If you want maximum performance and don’t mind having to service the diff, then a clutch based Limited Slip Diff is the way to go.

The 106 GTI and Rallye have the same gears, the VTR does not.

The 106GTI has the longest final drive and the shortest final drive is from the 1.3 8v Rallye.

1.4 106 is the next shortest and then 1.6 106 XSI and S2 Rallye.

Codes are stamped on the bell housing so you know what you are looking at.

If you have a sloppy shift there are many choices of uprated gear linkage on the market. Or you can make your own from rose joints and threaded rod.
