hi all

as we know my engines not in good shape atm

took it to my engine dude today and got a quote of what im looking at to keep this on the road...

the boar in cyl 2 is shagged. and is unable to be honed out, the only option to keep this block is to boar it right out removing 2.5mm of wall all the way around (180 or 108 thou i think he said...) and drop a sleave down and boar that out to the stock sizing....

lewis engines are a very very well known import and mainly RB engine builder, and he said that this is a very common practice.

i didnt like the sound of it too much at 1st, due to thinning out the side walls so so much, different things in cyls, different metals contract and expand at different rates etc etc etc...

just wanted to know what you guys think of this way around things.

i can pick up a motor in WA complete for $2500 plus postage (~$300)

i might b able to get about 1000 for bits and peices i dont need off it, thats ofcourse only if there buyers out there

or do the following to my engine

Fit Sleeve 180

sleeve 120

hone boares 180

Deck 150

2nd hand piston 25

rings (genuine) 500

linish crank 65

labour 1100

acl barings 190

seals 180 (main seal, oil seal and 1 other i think he said)

total 2690

this would get the block back in my hands ready to drop in an effectively at 0kms again, witch i do REALLY like the sound of! it will take 3 weeks to do,

do we think the rebuild is the best option seeing as i have put new just about everything in the car, and will keep it for years to come!

the heads already done, full freshen and port and polished, so that also is as good as new,

thanx people!

just by RBD2's wreck and sell all the other bits off.

if you're gonna go the recon route do it properly, new everthing - no second hand pistons or other money saving shortcuts.

And if you are getting Lewis to build the bottom end for, get em to throw the head and timing belt on for ya while you're there. lol

If your engine builder has measured all your bores and pistons and is convinced the other 5 have a good amount of life still you may as well go with the quote. If you were ever thinking of going RB30 now is the time but it would involve quite a bit more money to be honest. Your block rebuilt with quality rings and bearings should be ok for the 260 more or less? kw you were looking at some time ago.

err, we're looking at a 10k engine package vs a rebuild vs a drop in.......

depends how much longer you want to keep the car. if you think you'll change it over in another 12 months i'd just throw a cheap replacement motor in.

if you're planning on keeping it longer, rebuild it - but do it right. while you're in there, its probably not going to be much more of a stretch to bulletproof it. the other advantage is that you keep all the numbers on the car lining up (engine number to chassis number), which protects resale value.

if you just like throwing money at stuff, then buy the motor that status tunning has for sale. EVIL!

jdmspares is an ebay business, based in adelaide

the bloke is very nice, might do a cash deal for you, or buy back the head/turbo/loom that you wont need

he currently has 2 r34 rb25 Neo engines for sale at the moment, both for $2490 pickup @ lonsdale

http://cgi.ebay.com.au/Nissan-Skyline-R34-...=item5888e38466

http://cgi.ebay.com.au/Nissan-Skyline-R34-...=item588926f607

motors are complete with turbo, loom, everything bar ecu.

probably a better buy than the engine from WA seeing its local support, warranty, and could nut out a deal MINUS loom, turbo, and head possibly

buy engine for 2500 (after jdmspares gives you the engine compression report), sell loom $200, sell turbo $500, sell head $500 = engine cost approx $1300 or thereabouts. fit 100,000km service kit = fresh engine.

most cost effective way Id say.....

I wouldnt use secondhand pistons in the rebuild. for the cost of new rings might as well get cp pistons or wiseco to make up a Neo piston/ring set.... but I suppose that just costs more moolah.

depends on your budget.

depends if you want a 0km engine.

and depends o how quick you want this to happen (ie rebuild timeframe vs buy engine local & drop in)

all the best

doesn't it have to be an AWD block? either way i would be looking for a new block, screw the sleeving for 1 cylinder, all or nothing.

      Cleaning my wheels 😍

      By The Bogan · Posted

      I clean my wheels every time I wash the car, I also clean the barrels, the only product I use on the wheels is truck wash and a pressure washer, followed by (inset your chosen name brand) wash and wax, time per wheel is probably 2 minutes total, cleaning the barrels is easy with one of these microfibre thingies on a stick from Sabco, they're also great for getting in between the front guards and body, and tight spots in the engine bay

      An updated post here. Sounds to me like there's definitely a bit of sketchiness here.  Old mate with 10 rusting Torana's in the front yard might be more who they're focussed on. (For right or wrong).

      Is this not just about people wrecking, and storing, multiple cars in their front yard? I now a tow truck driver that was contracted by the council to clean up housing commission front and rear yards in houses and unit car parks I'm all for working on, and doing maintenance on your car in your garage or driveway, but some people definitely take the piss  There's one house locally to me that I walk past regularly where the front yard and driveway looks like a wreckers, multiple cars in various stages of being stripped, and the yard looks like all of fluids are basically dumped on the ground I may be wrong, but it seems that the initial reports, which I've seen nothing actually official about yet, may be getting taken out of context, like alot of the latest "the sky is falling" stuff found on the youtubes for clicks

      have they? Link appreciated. I live in Casey. I can see both sides of the argument in this case. There's a lot of sketchy stuff going on. There needs to be a clear definition of what this is supposed to be IMO. I wager the intent was to be a broad sweeping brush against people who have 4 cars up on blocks on their front lawn, not someone who services their own car behind their own gate on a weekend bothering probably nobody. But it'd be hard to legislate the difference there.

      Cleaning my wheels 😍

      By PranK · Posted

      Oh, the wheels were already off. I wouldn't normally take them off to clean them although it does make it easier with the ceramic, so I might take them off when reapplying. I don't drive much but now with the ceramic coat, when I do drive and they get dirty I can get most off with the pressure washer. I'll be switching to dirtier pads soon which was the motivation for the ceramic as I usually just clean them and sometimes use Autoglym wheel protector. Nah, f**k the barrels! Haha, I'll give them a quick scrub when they're off the car and a pressure wash, but even I draw the line with the barrels. Yes, dark coloured wheels allow you to get away with a lot!
