Okay so as some of you know....my spec-v decided to spin a bearing somewhere along the line a couple days ago. After much deliberation and thinking I'm gonna give it another shot. Considering purchasing a completely reman block for $2500....yes I love this car, and yes I HATE this engine. My question to all of you is IF I get a fresh or good condition QR25DE and do basic things such as: header to remove pre-cat, remove the butterfly system entirely (because f*ck failures), put a cold air intake on it, and a decent high flow muffler/standard catalytic converter on it. Will it be reliable enough to get high miles out of. Mine had 180K on it before it started to go berserk. Mind you that seems like a LOT but I come from the venerable 4.0L Jeep inline 6 which are notorious for hitting upwards of 350K without anything aside from basic maintenance. Basically what else am I looking at to make this thing reliable enough to drive a while and not worry. I have a relative low amount into the car already and managed to work out all the other bugs it has. I REALLY just need to know I can depend on this thing when I need it. I love the interior, the suspension, the brakes are fantastic, transmission is like glass, rims have no curb rash, radiator core support has been replaced before me due to a minor fender bender. all joints bearings and seals are working GREAT (aside from the rack and pinion leak) I like the car well enough to make it nice and take care of it....like it enough to buy a rusted pile of crap to drive in the wintry salt conditions and keep the Nissan warm in a garage somewhere. Just don't want to have to redo an engine every 200K because well that sucks.
