Was driving to work this morning, stopped at a petrol station, got back in car and noticed a knocking ....... had a better listen and Im 99% its the bottom end (Ive owned lots of 200SX's, I know what a bottom end failure sounds like) Sad

I bloody love the car (Ive got a 350Z, 400hp S13 and a convertible one, MR2 and various other stuff and would sell them all before the 6) and have spent a good few pence on new OE bushes all round, new OE shocks, cambelt, solid rear mounts, brakes all round ....... you get the picture Wink

Anyway, scrapping the car isnt an option, so whats the best way forward? I know a good mechanic who would be able to do the bottom end Id have thought, but I dont know if its engine out, crank regrind, oversize bearings and all that or just a 1 hour under the car job (I can guess though) Unsure

Or is putting another engine in a better option, mine has the cam advanced and pulled like a train, I would consider doing that again but would only want someone who knew what they were doing to advance the cam .......

Or as a crazy option, how much would an S/C build set me back? LOL

Any help appreciated, I cant face not having the 6 on the road No

How far was your cam advanced?

As above it's an engine out job, I think SC is the way to go as you'll have the engine out it seems like the perfect excuse Ninja

It'll take you about an hour to get the sump off LOL

To do it properly it is indeed an engine out crank out job, where you may as well replace all the bearings, fingers crossed the crank is stilll straight, and the conrod is still round and within spec, you couild just whip the sump off in situ and check the crank as is just replacing the big ends but is it worth doing half a job?

As long as that is all fine then you wont need to take the head off, and you can have the standard inlet advanced no problem.

Costs - £100 odd for bearings (I used o.e J4R big ends as they are £25 a set for std size, the mains are about £60 for o.e) a tube of sealant and some threadlock.

Then some labour for checking and grinding if neccesary, obviously doing it yourself will save a hell of a lot of cash.

How much by? I found after a recent belt change that mine was retarded by a degree or two Thumbs down After stuwee1983 re timed it correctly it felt so much better. So should be noticeable if it's advanced, just a bit scared of having it done though.

Nice one, its still a hit and hope on the crank though, or is it worth getting it measured (and where can I find the measurements?) Ninja
Basically Im asking how likely it is that the crank will need grinding (or replacing), is it worth just doing the shells first time round and hoping? Dunno

Sounds like a rebuild (large or small) is probably a better bet than a replacement engine with unknown history anyway, the mechanic Id have do it is ex-Pug and a drag racer so has rebuilt a few bottom ends in his time, and Im in no major hurry. Serious Q though, can someone point me in the direction of costs for a S/C build, the more I think about it the more sense it makes Big grin

Seriously. Thumbs up

Its more fun than most of them, more practical, more forgiving and much more suprising for your average M3 driver to find that he cant shake off. I keep mine debadged and dirty with a broken numberplate and a smashed foglight, and no-one gives it a second glance but in real life its probably quicker than the rest of the fleet 95% of the time, if not more (100% in the rain Big grin)

Bear in mind everything has been replaced with brand new OE, Ive got the cam advanced, I keep the geometry checked and with good tyres and the solid beam mounts its a joy to drive, particularly round corners.

As for pics of the others, oh, if you insist - I hate picture whoring, I really do Wink









Thumbs up

The most scientific Ive found is "a bit" Unsure

Carl did mine for me the second time (he had put it back to stanbdard position after a cambelt change), its not quite as advanced as it weas the first time but still makes a noticable difference Thumbs up

Sorry for muctilple replies, but hey, multiple questions ........ Wink

TBH, the Zed isnt a car to modify really, certainly not in the engine, too much $$$ for too little horses. The other two Nissans dont actually have anything standard left on them though Big grin

Anyway, back to my 6 - should I buy a new engine or rebuild the one thats on it? Dunno

I did mine earlier this year. Replaced the head gasket, 140 miles later, it spun a bearing so it was a complete rebuild!

Pulls like a train now and runs much better than previously!

Good luck

Best of luck with the rebuild mate, I assume you are going to go for it Wink

In regards to the supercharger conversion, I will PM you with the costs involved, and if you want to come out for a spin in mine, cambridge isnt too far from me Smile

Edit: I also love your threads of bigging up the gti6, means a lot coming from a Jap fanboy and its good entertainment sending them over to my mate with a 200sx Laugh

Yeah, gonna go with the rebuild I think, just cant decide whether to try whipping the shells out and replacing or doing the whole thing ........ any advice appreciated Thumbs up

As for the comments, I actually believe the 6 is one of the best cars ever - Im lucky in that Ive driven lots of stuff from old classics through to the GTR and a 700hp 200SX, very, very few Ive driven are as rewarding as the 6. Take that with 4 seats, a decent boot, cheap part prices and generally good Wink reliability and I dont understand why more people dont own them Dunno

Looking forward to a PM too, tempted by a charger but I really dont need any more stupid cars Whistle
