Just Picked Up A Peugeot Sport Flywheel

[jacobs53 0]

Well after alot of consideration I have decided that I want another peugeot project.

 

I was deciding between what though, and that was the hard part. After debating with the Xu and Tu engines I have decided to go for a TU build in a late registration base model 205. I am now stuck on which engine!

 

I personally think the 1360cc engine (xs) is a massive hoot to drive and engine seems so revvy. So i thought maybe use the bottom end as its alloy and very light. Then I threw the 106 gti engine into the equation and it all became confusing! The Tu5j4 (or whatever it is) is a nice engine and producing 120bhp out the box means its not low on power, but then all that keeps ringing through my mind is steel block!!!! And the weight penalty which you suffer.

 

So that got me thinking further... could you use a Tu 16v head on a 1360c alloy bottom end?

 

Gearbox wise (i'd like to thank Sandy for the advice!) I will be using a BE4.

 

I should mention that the car will need to be used on the road sometimes, maybe to travel to track events etc... So i'd want something that will be reliable..??

 

And final question of the day... Does any TU engine come with fully floating pistons? As i need some con-rods to fit fully floating pistons, which will fit inside the Tu engine

 

Oh and finally the picture, its a TU5 flywheel produced from steel and weighs in at 4.3kg

I think this is what a Martin Bowyer 1.4 16v is based on. On throttle bodies they are producing in the region of 190bhp (engine dynoed). I am sure Sandy knows a lot more about these spec engines.

Emm no picture??

 

How much was this Jacob and where did you get it from?

 

I was planning to use a TU3 fly with a helix cutch (171Nm 126lb Ft).

What the f**k!!!!!!!!!!!!!

What the f**k!!!!!!!!!!!!!

 

 

They are not exactly standard and not cheap either. I think Martin Bowyer is better known in Vauxhall circles but has just started doing Pug 1.4 16v engines. IIRC a Pug 106 running this engine whooped a load of scoobies etc to come 1st overall at a rally at Longcross earlier this year. I have had a passenger ride in another 106 rally car with this spec engine in and it was awesome.

Ok see it now

 

Swiss cheese Must be expensive...Be interested to know how much

There is a silver 1400 16valve 106 running round now rumoured to have over 200bhp. Its damn rapid and keeps pretty good pace with WRC cars at rallies.

A friend of mine has built a 14XE (Vauxhall 1.4 16v) which gave 204bhp on his dyno, with his "Rally" cam profiles, even he was suprised! Can't say much about though because he won't tell me much.

 

I'm building a 1.4 16v for a hillclimber at the moment, but can't say much about that either sadly, because if it's effective when it's done, then competitors might start searching for the details.

But suffice to say that the late 206 1.4 16v has an alloy block and although the valvetrain is different to the TU5J4 (aka complete poo), you could easily bolt a TU5J4 (or TU5JP4) head onto it. I can't do this however because the rules i'm building the engine to require an original 205 block, so I'm using the late TU3 Iron block, because it's easily modified for the extra cambelt idler and I don't want the risks associated with thin liners and high cylinder pressures. The car will be extremely light, so the extra 23kg of the iron block (whilst regrettable) isn't that critical.

Getting the CR up to an acceptable level is the only real issue, i'll be using custom pistons, but a skim on the TU5J4 head and the late 1.4 16v pistons should yield about 10.8-11.2:1.

 

I've just finished a TB conversion on a friends 1.6 8v though, and it's one of the best sounding 4 cylinders engines i've ever heard. If it was me, and not for competition, i'd be going 8v.

hi the price of the flywheel from peugeot sport direct is 1393.94 euro's, when converted to pounds sterling this is qqual to 935.33

 

I wish there was a 1600 Tu engine with a aluminium block, I don't understand why they didn't produce one.

 

Does anyone know if the TU range of engines came with fully floating gudgeon pins i.e. connetcing rods which are attached to the piston by circlips rather than a interference fit

Sorry I forgot to answer that, the 1.6 16v TU5J4 definately has floating pins, the 1.6 8v and 1.4 8v definately don't. You could use the 1.6 crank in the alloy block for 1449cc, as Charlie Saville did, but it makes it pretty long stroke and it probably won't perform much better than a good 1360cc in reality.

Thanks.

 

Looks very nice but way above my budget unfortunatly
