Hello there , I dont own a 406 but i do own a peugeot (106), and basically im building my engine to a pretty high N/A spec and i need bigger injectors, been told that the 406 ones are 200cc, could you tell me which engine have 200cc injectors, so i can go to peugeot and buy some!

thank you in advance!

You would get some good tips from Malachy on here, try and PM him, he's very clever with this stuff.

Also you might want to edit your thread title to read - What CC size are the 406 petrol injectors ?or something to attract more attention cos were a lazy bunch

should help you ut all you need is part numbers from people now

Cheers thats super!

Is it a 1.6 gti you have? Engine tuner steven gault in northern ireland can get them up to 200+bhp N/A

Well, considering that 100-110 BHP per litre is about the most you will get from an 4-pot N/A engine with Variable Valve Timing then these engine must run NOS?? otherwise 200BHP is not possible from a 1600cc.

No its not 16v, its a 8v, should be around 170bhp after, ive done everything on to it. in car that weighs 850kg!

It is possible to get 200+ from the 16v engine, Peugoet and citreon both have done it in their rally works cars

If you type Bic 106 into you tube you should find his 106 going around donnington in his 220bhp+ 106!

There you go!

Bye bye mr in the focus St and mr in the evo!

Welly, the TU5JP4 has 120bhp, with no VVT or VTEC shite, its just good old PSA engineering, the same engineering that achieved 167bhp from the XU10J4RS found in the GTi6, that power is wheel acheievable, i know i shouldnt compare it, but the Honda Integra DC5 runs a 1,8 16v lump pushing (i think) 200bhp, anything is possible, its just how much money you plan on spending, and how undriveable you want the car

You MUST have variable valve timing and high revs to get more than 100BHP/litre.

no VVT on either TU5JP4 or the XU10J4RS

Not really, but it's a big trade off on the low end power (a bike engine for instance). After all most VVT systems just switch over between two cams, so if you imagine runing just the top end cam you get the same result.

no you dont all vvt does is retain economy and run a mild cam at low rpm and a wild ass cam at high rpm.

slap in a wild as hell cam (300/320 dur) solid lifter 12:1 comp ratio, headwork with larger valves (31mm inlet) with decked block, 40mm Itb's rebuild the block with forged pistons, arp conrod bolts and head bolts for durability, lighten the fly wheel and rev the puppy to 9000-9500rpm and your on a good way to 180bhp at least in a tu5jp4

i know of a 1.8 16v psa engine thats in a 205 hill climb car pushing 240bhp again that revs to 10k rpm though

ok it will idle like a model t ford on full choke at around 1200rpm,

certainly possible though

i even know of a ford yb engine 1.9 n/a pushing 412bhp in a mk2 scort
no vvt there baby!


the facts;

412bhp@11500rpm and 211lbft@9700rpm on MotoGP fuel.

Cossie YB on TBs, de-stroked to 1.9 and 17:1 compression







No nitrous, no turbo just mental I love it!!

Turn up your spEk3rz

Awesome!

basically taken the cossie lump turned it na and tuned it to hell with super strong bottom end and insane compression ratio + mega revs = silly power

its simple really if you can make an engine rev and retain its torque at those high revs it will make big power

this is how honda's make there power there torque figure is nothing special its just the fact they rev that gives them the good bhp for an n/a the VTEC system just allows the cam shift for the ability to hang onto that torque at the higher rpm and to shift back to a "normal cam" that will idle and will pass emissions etc etc.

if you want to see the future of how engines will go watch the moto gp engines, Ducati desmo is a very clever valve timing control system (worth a google if interested) and even some bikes out there are running pneumatic valves with complete ecu control for valve timing thus meaning you can map your valve timing much like you can an injector, this enables you to have peak power across the board retaining 100% volumetric efficiency at any rpm any load no compromise. very exciting stuff (well if your an engine tech geek like myself at least) if this tech hits road cars it will make vtec look like horse and cart tech (which it is starting to now anyway vvti is superior)
