Xmas is nearly here and (because i'm so awkward to buy for) im just getting money! wahey!
And I feel like I need some more power from my mota!
I've got a 1.8 LX so as you can imagine 0-60 in about 2 weeks!
I still manage to rip up the corsa's and clio's at the lights but most of them seem to be beating me untill I hit 3rd gear.
Can anyone suggest ideas to increase the lower end torque/power/acceleration?
I know about chiping-does this give a good increase?

fit a 306 gti6 exhuast manifold

Buy a 306 Gti6, comes complete with said exhaust manifold

Will fitting one of these make a noticeble difference? I didn't know the 306 gti6 manifolds fitted the 406? sorry to be abit ignorant i'm guessing its less restrictive?

i have one to fit to my 406 i just cant be arsed to do it, apparently it will gain you 10 bhp and alot more torque, and throttle response is a thousand times better

I'm currently in talks with an engineering company for some discount, when I know you guys will know.... lets just say it will give you all the power that you'll need

what is it niz, if it gives more power then i want it

It will be a full on Turbo kit for your motor ! Bolt on performance lol

what about engine management and pistons?

Its a low boost application... FSE PBV should be enough for the extra air in the cylinders to be honest, as for pistons... they only really become an issue when there is excessive heat, so if the system is designed properly the extra thermal load on them should be minimal. I suppose if you want to change the pistons and stick on an aftermarket ECU...

Malachy can sort you out with a mega squirt system and pistons can be obtained for £450 then you can as a Volvo engineer, spend 2 weekends fitting it all

that sounds like too much effort

ill have to take my chances on the stock pistons

as a rule of thumb, your engine can take a 50% power increase before there is any detrimental effects on the engine, providing your thermo-dynamics are correct... thermal management is key...

I've pumped 18.p.s.i into a block that standard runs between 6 - 12 p.s.i max due to Peugeot's boost contrl mechanism and I drive it hard as hell and no problems with the std block or pistons, only weak ass headgasket's....lol Obviously each engine is different as there are inconsistencies in components!

The XU10J2TE produces 150hp a 50% rise means an output of 75hp extra taking the total to 225hp. This is a figure that Ecosse offer ( 220hp ) with or without forged pistons, obviously for longevity and sales they recommend pistons

PSA did build a XU10JT4E/C which was a turbo'd 2.0 16v engine ! yum ! obviously that would be far better than the 8v potential !

the stock engine management is crap and would never work with it, the ignition timing and injector duration will be all wrong, it will log a map sensor fault and most likely an oxygen sensor fault the first time you hit boost

You would be surprised... the lambda sensor will read greater Oxygen content in the exhaust gases and cause an adjustment in the fuelling, when your knock sensor identifies any detonation, it should retard the timing accordingly and modify the injector pulse duration and timings.. IT SHOULD as a learning computer that is.... failing that you could always go piggy back ECU !

I'm not saying that the pug system is faultless but it should work well on low boost applications...

I'd be tempted to try it if I owned a N/A 406, I'd be silly though and turn the boost up to silly levels just to see how much the block could take !!

i really want to try it and if its not too expensive i will

the oxygen sensor will correct to a certain level but when the o2 content falls outside (too lean) the speciefied parameter then it will go into limp mode, also the map sensor will be at fault straight away, as its only designed to read vacuum or atmospheric pressure
i will probably need a gti6 inlet manifold as the stock plastic one wont last long, even n/a they are known for bursting

in theory it wont cost that much as i already have a turbo, and i can fit it myself
