Anybody know where i can get some from?

GSR used to sell them, they dont list them on the site anymore tho and oldschool doesnt answer his PM so i carnt be arsed trying him

Kent or Piper?

Cheers

I believe the ones GSR used to supply came from Burton Power products, so could try them though got a feeling as they are a Ford place you may need to know sizes etc rather than say you want X for Y car.

cheers for the replys guys. Kent and piper totally slipped my mind even tho i order a pully from them today.

Will have to get the measuring gear out as both companys have a nice selection

i bet you could find some fitting on another car? take a bit of research tho.
btw... what cam you got/getting or you planning on silly high revs

*edit* machined your "bob" down today. the bottom was just over 4mm out

im getting a silly cam, and silly high revs, limiter around 8.5/9k

and before anybody says, yes the bottom end is getting balanced. Went to pick up the crank and f/w this morning but it still hasnt been done.

4mm out?? what the diameter or flatness

nice! btw the other day i was looking on eper and seen something on later seis that you may want to do a bit of research on (i would of if was was running N/A)

Modification code 9081
Description MODEL YEAR 2004, LIGHTENED VALVES AND NEW PISTONS
Activation MOT 2543171
Subcategory 10107/02 10107/03 10000/02 10101/01 10103/01 10301/01 10402/01 55101/01

*flatness, it was really low by the inlet. it was also out of square. just gotta get a new silicon pipe and ill try it out

mmm, i carnt get eper to work, i was going to do a bit of work on the valves anyway, but ill still look into your reply.

well the part numbers there. try http://eper.deltahpe.nl/

anyway the prices are:
exhaust: 11.39 each
inlet: 7.95 each
TAX not added.
Price not to bad! why not order one of each just to see what they are like?
they was one of the last mods fiat did to the sei.

doing work on a valve is a bit brave tho imo!
or do you mean getting custom valves? sodium filled exhaust valve

But i guess you just need light stuff on a high rev engine. and as fiat list them specifically as light valves. cant be a bad sign.

i get stuck on that eper aswell wont go further than the crankcase and cylinder head section.

use internet explorer or another browser. I mostly use google chrome and it hates it. causes it to go to the start page.

btw its not under cylinder head. its under distribution. first page.

FIAT \ SEICENTO \ 1E SEICENTO (1998-....) \ 101 MAIN COMPONENTS ENGINE \ 10107/03 DISTRIBUTION M3 - D9081

which engine you working on btw? im thinking 8v
im only going to rev to 7100rpm would be to 8500rpm if the ecu let me
so evan still need some stiffer springs with it being boosted

would getting stiffer springs aid my turbo setup on the p75 head?

yup your bottom end will be good for 8k rpm so yes its advised as long as your turbo holds boost up to there

what makes you think the head needs harder springs at 8000rpm? when i had N/A my ecu was set to 7800ish i had NO valve float what so ever. you really dont want to go for heavy springs unless you need them as they cause more wear on the cam and valve seats.

imo if you think its a problem i would look into the valves i told brooky about above.
lighter valves will lower the rate of wear while having the effect of harder springs.

gaz is wanting to run 1bar boost iv beed advised by a tuner to uprate them,
only get some slightly stiffer,tbo imgoing to do it for safety might not need them but the springs which were in the head could be tired?worn ?
will the lighter valves stand uo to the extra heat from the turbo though?
need to find out what material there made from
Zak

On inlet it won't make any difference (the turbo, that is), but note that those valves are waisted (or so it seems -- can't see any other way of loosing weight) : they'll flow better. For the exhausts, stainless would suit a tub better, but you really need bronze guides for stainless valves. Having said that, stock valves and guides seem to stand up very well indeed (and springs).

I'm running up to 1.3bar on std spings with no problem amazing how peoples opionion differs as i was advised it was pointless in a relativly low reving turbo application.

That would be my view, too. After all, if the revs don't exceed standard revs and the cam isn't humpty bumpty, what extra stress is placed on the springs? And what's up with a turbo application that needs 8k rpm?

Tom, you should fabricate a desmodromic set up, or go pneumatic........
