Id be wagering you may need more than rings.

im also prepared for pistons, cylinders bored, crank re done, is there anything else i should expect?? or while ill have the engine out worth changing?

put in some RB26 resized STD conrods with ARP bolts, an oil pump (nitto), the exhaust guides will probably be flogged out so they will need replacing, some decent valve springs, the usual stuff like cam belt and pulleys etc and if you can afford it a decent harmonic balancer. It will be good for around 500hp at the treads.

Sorry mate can't get the file off me mate. Doesn't want to transfer it over MSN to me, being a weak prick. It's a 120mb PDF file hehe.

However! Because I'm awesome, here's a direct link to an online one...

thats brilliant thanks soooo much, i was thinking about signing up to tafe and learning japenese hahahahaa

im pretty sure this topic will be going for a loooong while while i rip out the engine, ill try and take pics when i can as well hahahaha.

ill try and change over as much as i can in the engine, thanks for the shopping list guys, bit of a pain really the cam belt has only done 20,000kms lol had it changed not long ago!!

[stormtrooper]

No worries dude Good luck! heh

hey,

sorry to bring your world crashing down

but unless you have experience with vernier calipers, micrometers, ACL plastigage, measuring bearing clearances, .. can dial in camshafts etc

then its probably better to take it to somewhere like a hyperdrive in malaga or similar workshops

you might pay a small premium but the job will only be done once, not like f***king up and learning from your own experiences then spending double

because you forgot to check something or prime the oil pump on first turnover. not saying your a muppet, it's just that engine reconditioners

etc spend a decent amount of time learning their trade and if anyone could do it then they wouldn't be in business.

i have had a few mates rebuild engines even tradesman but they were no engineers and the motors in question were lucky to last 20,000km

in any case, dont just smash a second hand wrecker engine in there!!

do it right first time

good luck mate!

thats what has also been running around in the back of my mind!!!!

i was thinking about taking the engine out then paying someone to rebuild it? all the garages say a fewk is just labor taking the engine in and out, i think that might be a better opition, i can change headgaskets and things like that but as u say, im defo no mechanic lol

i might give hyper drive a call and get a price so far all garges are up around $8k :-( the car only cost 13k lol

[LANDSCRIBBLE]

Hi, im curious as to how and why the piston rings have gone? ive heard its from overheating or something? Would be good to know so i can maybe avoid this problem in the future.

Thanks.

[Spynic]

in my case its call skyline owners for 180,000kms :-)

wear and tear, like everything, but lack of oil and overheating can cause em to warp or split :-)

[LANDSCRIBBLE]

thanks for the input spynic, will be sure to be on top of the oil level.. i heard it can also be caused by running lean?

[Spynic]

i guess if u runn silly boost and dont have the system back it up then yh it doesnt matter what it is something will pop hahahaha

just make sure everything is done properly and you should be fine

[Spynic]

honest opinion if i may,

would it be worth trying to sell a car with blown piston rings :-) looking at getting aroun 7k ish for it?

[SKYRYAN]

Just buy a 25det from a wreck and swap the engines over. Sell your engine to someone who wants to rebuild a 25det.

hey man!

you will save money by pulling engine yourself but then you have to deliver and pick it up from reco place...

also your warranty from engine builder may be void this way

end of the day you have to make some decisions

- how much can I afford to spend?

- do I just need it running to get around?

- will I be looking to keep this car for a long time?

- what are my goals with the car? track/drag/drift, street fun, daily run around some hp

another option would be to take it somewhere budget orientated like KYP in welshpool, have a second hand wrecker engine fitted

for 4-5k, then keep your old engine on a stand and build that up yourself over time. there are some good books on the subject

you can get and that way there won't be time/finance constraints.

cheers

KYP is a good place to get a 2nd engine

and its unlikely to sell a 33 GTST for 7k with a blown engine

Running ones on carsales/quokka for Series 1 are from 7-8k+ or 11-12k+ for Series 2

*shamless plug* My mate has a 25 block, forged pistons (needs rings) and GTR rods for sale
