Pretty sure Rollinz was running uprated Cat Cams 106 GTi springs, which happen to have the same part number as Zetec ones!

SBT83

I'll keep my eyes peeled for a set. I'm sure I've seen a few pop up on eBay tbh.

higgsy91

Get the retainers too if you're going blacktop. http://www.ebay.co.uk/itm/Peugeot-10...item338243a62a

20 psi on standard gti springs?

Doubt you will do a thread about snapped springs, but I will put money on having valve float/ bounce or misfire or unable to make power

SBT83

Cheers dude!!!
Just bought em

higgsy91

No worries man, keep an eye out from that same seller, i bought the springs from him too. He's often got full sets up on there

SBT83

Your the man!!

I'll keep an eye in him, I'm not in too much rush, but I'm thinking by late jan I want it ready and running

higgsy91

haha! i said that once, a year later here i am, still no engine in.
Good luck though!

SBT83

I know! I've said it many a time myself

It needs to be done in time for York so I've got a an ultimate deadline for June. But that's for the complete car lol

QplateRST!

It's about an hours work to change valve springs once the head is off I did a set last night

SBT83

Whats the best compressors to use? Any that should be avoided?

higgsy91

Yeah about an hour for a straight swap but once the head is off you may as well lap the valves again. It's taken me nearly 2 hours to do a good job on lapping all the valves. Really satisfying once it's done!

Go for a decent set of multi-valve compresssors. Machine Mart was where i went. http://www.machinemart.co.uk/shop/pr...ing+compressor

Excellent info! Have some rep

I borrow a mate of mines that work at a ford dealership in blackpool

I paid an engine builder £30, saved me the hassle lol

SBT83

I thought you only had to Lapp new valves and not the same ones as they are already bedded in?

higgsy91

Just to let you all know, i fitted the springs today with the 106gti retainers too. fitted together a treat. Super stiff too.

SBT83

keep me updated dude

Yes I use the ST170 springs but as Stu points out they are for black top heads, I've not compared but I would guess they will not work as silver top engines have hydraulic lifters and black top's are solid.
As for their limit I ran 24psi (.48/60 T3) without issue.

Because boost pressure (MAP) acts against the springs trying to open the valves, the more BHP your running the greater your boost pressure, the stronger the springs need to be.

SBT83

Karlos your the man! You ever tried 106 springs then? What's your thoughts about using them?

higgsy91

+1

I've not mate no, most of my builds seem to be either low budget low power which need nothing doing to the head or ST170/black-top based builds and so I use the springs from the ST170 head.
I've also been told (but never tried it) that you can shim (2mm or 3mm washers IIRC) the stock valve springs to increase pressure a little, this could be another option for people wanting a medium power budget build.

higgsy91

Can't see this not working. Apparantly stock are good for 7 p.s.i. so a washer has got to give you at least 10 p.s.i.

On a side note.. as you have done budget builds, i'm going to use the stock 1.8/2.0 manifold, rail, regulator, throttle body but FRS injectors. Would i encounter any running problems with this setup? I'm going to use a cossie brown IAT sensor on the boost pipe rather than the FRS elbow too.

You'll have no problems with that mate, will all be fine to use.
Assuming you have suitable management of course?

higgsy91

Lovely to hear, yes i'm going to use MS2 with WB Lambda.. No idea how to map or where to get it mapped near me though, but will cross that bridge when i get to it.
Would you advise to install the ECU while the engine is in or out of the car?

SBT83

I wanna know where to get these shims washers made up. Can't get them from work their to busy. Uh oh pmsl

higgsy91

You won't find them anywhere trust me i looked. Got to be made!

higgsy91

Another think @KARLOSG. I will be using the standard reg, but i have a big powerful Walbro 255 pumping up the fuel, will this cause a problem?

SBT83

Any chance you can help me out with your source? Pennies your way

higgsy91

Well my source was a girl that i was seeing for a bit.. so.. can't really go that route for you mate lol.

Although, you only need the shims for the inlet side technically, i did both sides because i had enough, but it really isn't important to have them on the exhaust. You could even leave the standard zetec springs in on that side if you wanted..
But anyway i think i have around 8 left over...

SBT83

How's about we sort a deal out?? If you do have 8 that is??

nevsrevs

just a heads up, you actually want to pay more attention to the exhaust valves more than inlet. I have uprated singles with shims under the ex springs.

plus ian howels got the shims if you're after a set.

SBT83

Has he only got the 1 set?

nevsrevs

he should be able to sort out a few sets, or let you know who makes them.

Karlos G

iTrader: (4)

Makes no difference but if your going to have someone else map it then they will probably want to install it too... I know I would, I've spent hours fault finding a poorly/inexperienced installation causing problems.
Will be fine mate.

Find someone with a lathe and 10 minutes free time. I had a load made last year by a local engineering shop, I think 100 cost me a fiver!
Just grab a used stem seal for the od and id measurements, need to be 3mm thick iirc

SBT83

Excellent advice! Thanks matey.

someone send me some shims and i will get them made up from a local who is great

made my caliper carrier spacers for 4x4 cossie brakes on a mk3 fiesta for £10

drilled and helicoiled my inlet for custom fuel rail and fitted it all up with everything £12

and made a custom charge carrier for my old s1 with swaged ends and sensor outlets for £40

hes brilliant, his company is called spot on throttle cables........

so as the name he can make custom throttle set ups too
