rebuild time?

[michael_r33]

hi guys i need sum help badly. i hav an r33 gtst and in the last week i hav noticed that its been getting slugyish the more it gets driven. the engine sounds like its a rexxy wen im driving it and am concerned about the problems. i hav also been told that theres blue smoke cuming from my exhaust inbetween gears and hav noticed it myself at hi rpm, especially in 1st gear. i hav a new hi flow cat which is 3 weeks old aswell. i hav been told 2 possibly check the compresion in the cylinders but i hav no idea how 2 check that, would ne 1 know at all? i hav just noticed theres a fresh oil leak jus near the turbo but at the back of the engine possibly above the dump pipe. my cars gauges read rich wen im driving n would that b wats caused this or sumfing more serious? do u's fink its fixable or time 2 rebuild? and how much would it cost 2 rebuild and who would b the best?

Take it to a mechanic... You're not going to get any definitive answers over the internet.

slugish and blue smoke = the engine is on its last legs , get a compression and or leakdown test then you will know for sure but its rebuild time for sure .

rb engine rebuild ( depends on the job they do ) from $5 k up including r+r engine .

then while the engine is out you do your turbo and a clutch and the $ go up

sounds like a rex could just be a missfire, i love it when my car turns in to a WRX, my injector plugs are a bit dodgy so i gotta wiggle them sometimes (eek)

i checked my engine last nite and theres a shit load of oil in my last cylinder and my plug was filthy only after 2 weeks. a mate finks it could b a piston ring. wat do u guys fink?i was quoted $6000 2 rebuild it with performance or $4000 so its standard.i hav yet 2 put it back 2gether but will hav it dun by 2morrow.all the oil that was in the 6th spark plug was a very big wory.

Yep sounds like one of your cylinders is shagged man. Best to do a compression test just to make sure before you hand over the money for a rebuild.

you have to do a compression test + or leakdown but from what you said its not good news . if you can get a rebuild with new oversize pistons you have to bore the block ( forgies are about the same as nissan ) , grind the crank , new undersize bearings and service the cilinder head + remove and reinstall the engine , all for $ 4000 its good .

you are looking at about $1800 for parts + machining and strip and put back together .
