Thankyou for that info mate but am hoping they last for a good few years not hoping after 6 months they will need checking again? But I see where your coming from have you got a link aswell for them rings so I can have a look please.

I will do bussey mate won't be down the unit where my startlet is till the weekend or next week but I will as it's bugging me like crazy to know if it's right

I have spoken to someone at yours idrees and thankyou mate

Still in two minds about changing my piston rings while the head is off the car, after checking them Rob H did explain to me in this post which I posted up below.....

http://www.ukstarletowners.com/topic/77037-piston-movement-in-bore/?fromsearch=1

But I'm still in two minds about the whole thing maybe I should get a video up of the movement in the bore just in case it's normal but on the other hand if I do have to get a new ring set which are the best ones to get for standard size pistons, I can't see how the slight pistons movement in the bore isn't normal when compression test showed all good late 150's early 160's and engine was built last May.

Thanks Pat

Well done for finding it mate 👍

Thankyou for the info there Adam 👍 gonna stick with the oem one will get one from id-workz

Only Liam_D can answer this Azz as I sent two turbos off to him the first one I sent is the one which went on the dyno making 195.7 Bhp but soon after it was shagged was a 2nd hand one anyway from dodgy bloke on eBay telling me the same story no smoke or play

Thankyou so much rob for that information I think you have totally nailed this on the head, also since I had the car and owner before both used 5w 40 fully syth oil maybe I was thinking there shouldn't be any play at between the piston and the bore seems to be up and down that's when we checked it when pistons were at top of bore, pistons and rings in there are only about 8 months old, plus bore been honed etc etc when it got done 8 months ago

Hopefully someone who knows these engines inside out will know 👍

Yes Azz just stock ct9 got mods on too like uprated walbro pump sard fpr fmic things like that I thought a td04 was good for 240bhp around that area

Please bear with me here as hope this makes sense.....took my head of today due to knowing by research I need to change the valve stem seals (bearing in mind before I go on my starlet had a full engine rebuild with receipts which I have less then a year ago) a week a go a compression test was done all about the same in the last 150's so that's fine, anyway back to, today, head off then we looked at the pistons just to see while the head is off, when we rotated the crank pulley so 2 pistons were at the top there was alittle play in both pistons 2 and 3 and also same with 1 and 4 when they were at the top too when I say play they moved up and down a mm or 2, (never had piston slap before it knocking when the car was running) also my mechanic done some leak test what ever he put in each bore just to see if it would go down, and in time it did very very slowly though, whatever it was it was very thin, not as thick as oil, which of course has gone into the sump, to me is it the rings? Everything else seems fine, I can only think seing as it's been rebuild in less then a year ago it has the wrong size rings on? It's kind of got me thinking alot here, as what I have just said May be normal on starlets just need to know before everything else goes back on, sorry for the long story hope it all makes sense.

Thanks Pat

Azz mate I got a print out here running 0.7bar @ 195.7 Bhp had it done last month but maybe you could enlighten me on more thanks mate

I will so thanks mate spoke to id-workz yesterday so in the process of sorting one thanks mate

Still a good price even if it did need a rebuild from liam_D 👍

I thought you had to go thicker for more boost Adam? Now this is getting confusing

Thankyou for the reply guys yes I will be sticking to this and if and I say IF I went bigger turbo etc I would know to change the head gasket but thankyou for saying now can just get a normal one

Pat

Surely a uprated FPR would help aswell hence why I put one on mine

Have mentioned this before due to the valve stem seals need changing I'm of course doing all the gaskets as you do and Cambelt/water pump and so on, My question is with the head gasket running around 200bhp @ 0.7 bar now my new turbos back and ready to go on plus have an hks actuator aswell to put on will probably put it to 0.8 bar running around 210bhp maybe? Was just wondering will a normal 4efte head gasket cope with it? Heard they can handle up too 1.2 bar on a td04 I'm never gonna be running no more then 1bar on mine anyway and only have a ct9 don't wanna spend unnesserary money if I don't need to as won't be going down the more power route on my starlet anyway, anyone have any advice please on this.

Thanks Pat

Thanks mate 👍

Thankyou for the reply mate will do 👍

mosley why not send your turbo up to liam d at midland turbos and get yours rebuilt ?

+1 good idea 👍

Hello dusty silly question which people am I asking on here 😄

That's a good point dusty thankyou just having trouble finding a good head gasket kit just need to change the valve stem seals but of course will have to do the whole top end as you know just can't find anywhere online that does just top end

Just alittle advice when I get mine back please what's the best way to get the the oil in the fmic and pipes out and anywhere else it should be sitting?

Anyone? 😁
