Wossner forged pistons or the one's K-tec use?
Who'd you recommend matey?
Oh well, think I'll go with K-Tec forgies...
K-Tec haven't let me down yet.
what's the difference?Wossner forged pistons or the one's K-tec use?
[quote=Scoff;94925]Fit some well known brand forged piston into new standard liners and build yourself a good but otherwise standard bottom end. That will do fine for whatever you want to do.[quote]
Thats what i would do if i was going to change anything on the bottom end!
Price.... K-tec sell theirs for an extra £46.
I also was looking for some feedback as to which ones people seem to favour.
They may be wossner or those PEC own-brand ones. Not that there is anything wrong with either, but I'd be a little more comfortable with a better known brand.
so why pay an extra £46 for the same thing?
Oh sorry, I hadn't realised they were.
Scoff, which brand would you go for mate?
you just said that they wereOh sorry, I hadn't realised they were.
Ive got some pistons and liners for sale......
...
Did I fcuk. I wanted to know which ones people favoured here, but that seems to be a problem for you.
SHameless.Ive got some pistons and liners for sale...
Buy them....180 quid delivered...you dont need to go forged this forged that
Na... I'm gona have to go "thanks but no thanks" instead.
They'd be no point me speaking to the guys in the know if I did.
People will still give advice if you do fit standard pistons mate, to be honest i can't see the point of fitting expensive forged items when the originals will do. Unless your going to be pushing the engine hard then i'd prob invest in them.
I'm going to aim for 250 bhp despite how hard it will be to apply it.
If you want to go for it mate then yes go for some forge ones, one thing i will say is if you are aiming for high bhp i'd sell that KTR cam you have and invest in a better or custom ground cam as that cam will not get you anywhere near that sort of power.I'm going to aim for 250 bhp despite how hard it will be to apply it.
To get to that sort of power it won't be reached with off the shelf bits
I don't know really, I just think that when it comes to important stuff like that you aught to put something you trust in there. JE, accralite, arias will all sell you something that will work perfectly. I've seen a few too many wierd issues with wossner to be 100% comfortable with them, but that may be because so many more people buy and fit them compared to other brands. And then there is the PEC imports of un-known origin. I have a phobia of buying stuff from people who refuse to tell you the brand. PEC are a bag of tossers to deal with diretly, the most unhelpfull set of clowns I know, I wouldn't buy anything from them on principal, let alone because of my concerns about their products.
Appreciated mate.
There's definitely going to be some obstacles in the way, but I'd just like to have the foundations there to slowly build upon.
Who knows, the efi route may be the way to go eventually.
Ok, cool... I'll check out JE, accralite and arias.
Regarding PEC, are these the guys you suspect K-Tec source theirs from?
this is what happens to wossner forged pistons and pec conrods

yyeeouuch.... did they lean out?
What set up and boost were you running by the way?

Engine is coming out this Saturday.... looking forward to getting the old girl going again!!
just ran the engine in and it gave way at 22 psi the carb is set up to run 30psi
J.E's, as I posted on page one of this thread...
Sh!t, that's not good. Sorry to hear that mate.
I'm definitely going to be running a AFR gauge when it comes to turning up the boost. That and wearing home made stethoscope running back into the car from the engine for the first high power run.
Sweet.
I emailed JE, Accralite and Arias.
If you're gonna fit those pistons to o.e rods, you'll have to get the rods machined to accept the floating pin.
Shouldn't cost you that much, but it is another outlay/aggro of finding a local company who can do such work.
Ok, thanks for the heads up.
I've got a friend who may be able to help with that.
Can anyone help with these questions: Please advise bore diameter and whether fully floating or press -fit pin?
I intend to use the original con rod if that makes a difference.
Ted, do you know what skirt clearance you were running? Had smiliar on something else, was a rebuild on old pistons as a favor, mic'ed up ok, but pulled up the bores. Issue was the skirt deflects, but not around the / by the boss support for the pin. They then pick up on the edges of the piston and not the main centre section of the skirt, looks like similiar if I'm reading your pics right. Just need to slightly increased clearance. Cossie boys have the same issue, and generally go at 0.07 - 0.08mm.
lol you did
never measured the skirt clearance because i ran these pistons for over 12months on standard conrods at 25psi + of boost,now fitted pec forged floating conrods which have caused this problem now i got to hone the liners out to make more clearance
PM'd
rob, it could have been that the piston was distorted when the old pin was pressed out - since you mentioned the piston didn't seem to rock on the gudgeon pin properly before fitting.
Just out of curiosity, what made you go for the forged conrods after the running the standard ones?never measured the skirt clearance because i ran these pistons for over 12months on standard conrods at 25psi + of boost,now fitted pec forged floating conrods which have caused this problem now i got to hone the liners out to make more clearance
i have all the tecnical data at home regarding wossners sizes of rods, i went for the woosner rods just out of simplicity due to the gudgeon pin slipping out due to the rod being over heated but lost my trust in them and went for c clip style.
just wanted to make the engine stronger so i can try and get more power out of it
Bollocks.
Ok, I was just checking that's all... just incase you had problems running o.e conrods or something.
Sorry Mart, only just spotted this since coming back to this thread.
Just emailed J.E.... just hoping there's a quick turn around for delivery. All other engine bits are now on order, apart from a custom cam.
Any recommendations on what cam to go for (aiming for around 250bhp)?
Man, I am Skint Eastwood!!!
Match the cam to the turbo.
J.E's are v good - You won't have a problem with them.
I've used JE pistons for my last rebuild.Till now they are ok.
I think they are the same.They are wossners an I think they are the cheap ones judging by the size of the conrods.Wossner forged pistons or the one's K-tec use?
What sort of money are we talking for a custom grind cam from the likes of catcams?
Not sure about CatCams, but Kent Cams charged me ~£120 back in the day.
I think Piper was a similar price too - Sparkie should be able to confirm that, as he sent a few sticks Piper's way to be re-ground over the years.
Re: Power - What route to go now??
Take a step back, Have a good read, Then what it will explain if you read all infomation correct is that if you dont listen to, sound good advise given in this topic
and try and stay well within your limits.
Your going to end up with a broke car sat there pissing you right off.
Its not just about bolting this and that on, there is a fine balance when it comes to silly power 200bhp + on these little turbo engines, 1 mistake major fail
if you have enough coin have a play and learn the hard way......
if not i'd ask the question you just asked and got plenty of good ideas,
remember the more money you spend on said engine, if and when it fails running high power , its going to cost you more, so keep it cheap but and listen to what people say.
You can have standard engine, decent cam, nice lungs "turbo" good air/oil/water cooling and have a reliable 200hp without it costing a packet.
like you said further up in topic joining RTOC is well worth the £25 squid and will save you a lot, like it has for me. no point getting carried away thinking you can out do people who have got borad trying to get more power out of said engine
stuart clark has the fastest and your not going to out do his car
its for sale i think why dont you just buy that

Ok, cool. I've heard "Catcams" being thrown around these parts so I take it they're a recommended supplier. I may give them a call.
Cheers Mart
Sure, I wouldn't be posting on this thread if I felt otherwise.
Noted.Its not just about bolting this and that on, there is a fine balance when it comes to silly power 200bhp + on these little turbo engines, 1 mistake major fail
Yeah, thanks all the same, but it's time to move on and up the power. I'm not looking to "out doing people" on here. Why would I? I don't even know anyone on here and to be honest, there's always someone out there faster, minter, better, anyway.... and fair play to them. I don't quite know how you've come to this assumption....if you have enough coin have a play and learn the hard way......

Can I not just find the tolerances and options of tuning my engine without people telling me what I should do?
