Tureno 4agte engine rebuild :D

[ae_86]

Hi all blow my engine on my ae86 Decided to rebuilt it with stronger parts and hope of some better reliability

any way here are some pic's

here's the car looking sad




Now you see it


Now you dont magic!




also has a os Giken super single clutch which is nice the only thing bad about is its pretty worn out which is not nice as a rebuild kit cost 300+ quid

also striped the block to see what had failed a lot of guys were saying that the ring lands have gone and I was thinking it was the piston rings which have failed but both the rings and the ring lands are f***ed

piston no.1 bottom compression ring has multiple cracks and the ringland fell apart in my hands




pistons 2 and 3 were ok

piston 4 had some cracks on the ring land




thats all for now will update when I get more stuff done

looking forward to the rebuild project

Typical 4age problem... my first engine did that too.. Think it's overheating / bad lubrication or something similar. Usually nr4 cylinder that gets the worst of it iirc.

sick, but maybe look into a bit smaller turbo ? like a gt25? that would still make 300 hp. But will make the engine more durable ?

too late now got the turbo already should still be ok tho

back to the build

here's my work bench the boot lid of my skyline lol :lol:


the block cleaned,sanded down,sprayed then cleaned again ready for bearing and crankshaft installation


crankshaft installed and torqued down



Now the next part is to measure each piston ring and file it (if needed) to spec's now this is a long because you have to put the ring square in the bore then measure it if it to small(which they all are, none of them are the right size out of the box) then you take it out and then file a little then place it back in the bore measure and repeat until it the right size and you have to do this for every single ring!! :yawn: lets just say I started at 11am and finished at 5am in the morning!! :yawn: (Watch the SR20 rebuild vid I posted to see how it is done)


Mounting the arias pistons and the spool conrods looking sexy :thumbsup:

putting the bloody rings in lol :lolI never want to see another piston ring in my life!! :lol: )


pistons mounted and torqued to spec

ok so more pic's, I sprayed the sump in high temp matt black which I think looks pretty badass B)

oil pump,sump,driftworks sump plug and the kelsport bolts installed and torqued down to spec



closer pic of the matt colour and the bolts



I liked the colour of the sump so much that I had to spray the cam covers the same!







next the arp head studs installed

[ae_86]

pic's of the ported and polished head done by me which I think came out Ok could have spent more time on it but it all good



valves in

shim and buckets cleaned and ready for installation

HKS metal head gasket installed


Head installed and torqued to spec



camshafts installed



a quick pic to see how the covers look like on the engine (I know there in the wrong way but hay it was 5 in the morning and I was tried :yawn: :lol: )

[ae_86]

ok some more updates

backing plate cleaned and fitted



Cam covers cam pulleys and hks belt installed looking sexy.............hhhhhhhmmmmmmmmm purple... :drool: (sorry for the crappy pic's )



Some of you may have noticed the cam cover's are different colour,I dropped some parts cleaner on them while I was cleaning the garage (Doh!!) ran out of that High temp matt spray went to my local halfords but they didn't have any so I just sprayed them satin black which I had lying around Going to spray the matt black later on just want to get the engine in and running!! :Jumpy:

new water pump installed


A quick preview of the clear cam cover B)


rest of the water pipes alternator etc on


more pic's of the cams and the HKS belt some of maybe thinking why is one of them look newish and one of them look old well I had them in my Gti but I did not have them covered up so I am guessing some dirt and grim got on one of them and took the paint off still looks good tho my thinks


pic's of the clutch
cleaned the clutch cover came out well also looks really cool you can't it in the pic's but its like multi-coloured if you look at it in different angles it goes purple,gold,green,different shades of blue looks badass shame you wont see it when its in


new clutch plate,bolts and the thingy plate lol dont know what its called :lol:

flywheel and arp bolts installed

inlet,exhaust and turbo installed


engine installed magic!!


will get some vids up of it running :thumbsup: sounds really different
