Recomend Me A Set-Up Please.

[Ian205 3 1 Cars]

the time has finally come to throw a hat of money at my engine, not having bought alot of internal parts before and other people not willing to recomend anything iv decided to ask here,

 

at the moment what i have,

 

piper cam (unknown model)

magnex exhaust

 

std pistons, injection

 

k&n 57i induction kit (probably be seeing the shelf to make way for itbs.

 

engine is being built for tarmac rally

[welshpug 1,627]

Why std injection? Thats the first thing I would ditch.

 

add 1.6 pistons, std compression is a bit low.

 

add a ph4 newman cam and bodies, 170-180bhp.

 

double valve springs would be wise.

Is that with head work as well?

To all intents and purposes yes, looks like someone has tidied the casting marks but nothing much else done, certainly not a "big valve ported flowed yada yadda stage 69 head"

forgot to mention i bought the car with the above already fitted, and am slowly but surely building it for tarmac rally. my engine is 1600, maybe im in the wrong section.

Ah, 405 sri pistons then

[Ian205 3 1 Cars]

are they an oem peugeot piston or are they just conveniently named 405sri ?

[welshpug 1,627]

 

Specifically the xu9j2 engine, they have a flat top due to the larger chamber in the head, so in a 1.6 gives a good amount extra compression for running lumpier cams.

so 405 sri pistons

newman cam & bodies

 

as for bearings and gaskets?

add a ph4 newman cam and bodies, 170-180bhp.

 

double valve springs would be wise.

Double valve springs will be mandatory. The ph4 cam has 0.490" lift. It will definitely spring bind on standard springs.

I'm looking at a similar spec myself and am just getting my head around all the parts/machining required so that my car is off the track for as short period as possible.

 

I've been looking at the Kent double valve springs (http://www.kentcams.com/product-details/627/Engine-Component/Valve-Spring/VS52-Double/#fragment-4)- what work is needed to make them fit? Presume seats and retainers would need machining?

[petert 554]

If you're a tight @rse like me, you'd make your own spring bases and machine the standard retainer to accept the inner spring. Otherwise, companies like Kent and Catcams sell kits. Either way, you'll need to machine around the valve guide to allow the spring seat/inner spring somewhere to sit.
