There is no way that I will be buying a second hand motor, my wife won't let me waste that much money for more problems.

I trust my machine shop to do a good job.

A second hand motor is guaranteed to be build perfectly with zero issues, it isn't guaranteed to have had a good life, however unless someone has put an aftermarket ECU on it and turbo with bad tuning causing it to detonate, or had oil starvation there is almost zero chance it will fall apart. A great way to get a known motor is to pull one out of a crashed automatic car with stock everything.

A build motor is a complete gamble, has the builder built these motors before? Remember the guys at nissan were spitting out 10 motors a day for years, they were absolute professionals in everyway. If you build a motor how do you know the parts won't have issues, how do you know they will balance it properly, can you trust them to get the tolerances right, can you trust that they will even measure the tolerances?

What about if they bore the block, will the use a torque plate? Will they use a proper torque plate? Was the head they used on the engine warped and machined flat, if so it could crack the camshaft 10,000kms later (mine did). What about preparing all the parts, will they use the correct lube? Will they use plastigauges and check the tolerances a second time when everything is torqued together?

What about simple stuff like installing the rings correctly, they might have done it before but accidents happen.

As you can see there are a 1000 places you can go wrong with building a motor, if the builder/assembler has not done an RB before bail, if the builder has not done 10 RBs before bail, if he has not done one in the last year bail. You want someone who does these engines every month. Do they offer a warranty? If not why don't they? Do they outsource labour to other companies eg machining etc, if the machinist stuffs up and he installs it and the motor dies will he warrant his work or will he tell you it was the machinest fault and not his?

End of the day you should just buy a short block from a reputable workshop like red r racing, racepace etc.

Saying "I trust my machine shop to do a good job." is like going "lalalala" and sticking your head in the sand, you are just hoping they will do a good job, you have no idea if they actually will, they might do the best job they can, but how will this job stack up against nissan? It is more of a gamble than buying a second hand motor, I can guarantee you this. I see more popped rebuilt motors than I see popped stockers.

i under stand fully why buying a 2nd hand motor is a bad option, thats why im not really considering that an option, i could buy an unknown km/condition 2nd hand motor and it might only last a few weeks, id prefer to spend $2000 building a brand new internal motor, keeping my matching numbers block in the car and having it built for alot more power then i will ever make with it. then i will know that nothing is going to break in a few months time.

An unknown condition 2nd hand motor is no differnet to an unknown built motor. Who says the built motor will hold more power? How do you know it will? How do you know it will even hold stock power levels? You don't, you are just guessing.

A stock motor is going to cost you less than half the price and imo has even better chance of lasting, don't buy some random motor, buy something with some history, eg I found an automatic R34 that had been torched, everything was 100% stock and unchanged, even had stock rims and exhaust, pretty good guarantee there.

I bought a $9000 rebuild rb25 with forged everything, the motor was a piece of shit, the camshaft snapped, the thing rattled and leaked oil, everything was loose, wrong gaskets were used, all round it was rubbish, luckily I basically got the engine for free with the car, and to top it off this was a well known performance skyline workshop that built the motor, they just weren't well known for building engines.

Either buy a stock motor with history, or buy a short block with warranty from a proper performance engine builder with a known reputation, anything else is a gamble and I highly do not recommend it.

I can you see where I am coming from here?

I see what your saying.

Is there any known rb builders in south east Qld?

I really fail to see what businesses are thinking when they don't have web sites. I wonder if rips will rebuild my bottom end if I send it to them.

Do you expect the builder to do a good job if you are paying $2k for machine work and labour?

In another month you will start the thread "Is it normal for a built motor to be noisy and blow smoke" and then your money pit will be for sale for $3k with a dud motor.

you definitly want a builder with RB expertise..especailly seeing as how much problem you have had already. My mate builds and machinings all his

motors(hes a machinist by trade), and has built lots of tuf Rb's....theres a few tricks machining the oil galleries and bottom end clearance wise to make them live.

I have seen that many monkeys f**k them up its not funny..lol, especailly blocks bored with a torque plate and ended up with oval bores, used to happen alot 10+yrs ago when v8 machinists started building jap stuff, alloy blocks are worse, but seen big dollar Rb30's f**ked the same way

I thought neos used an n1 pump?

My turbo is a hypergear atr43 ss-1. I'm planning on running about 220kw at the wheels.

errr hope not, you would spend half your life, cleaning out a catch can, or redrilling your 500th restrictor as the other 499 didn't stop the oil pooling up in the head..

you wife will love the smell of burning oil in her nice family car..lol

stock pump ftw, my mate doesn't use collars, he welds the crank and machines it down to fit tight over the pump gears..way better fit, way better quality after seeing how some of the

big dollar collars are attached, but unless your limiter bashing you probally don't need even a collar.

If it was me, i would rebuild it as a stocker(no forgies),but paying attention to clearances and machining/oiling systems

it would be better than a stanadrd motor(if you get the right person)

Give the boys at SPOT ON PERFORMANCE

@ randal st slacks creek

Ask for Andy or danny they are personnel friends of mine

They have both worked on And built rbs and will be able to help u out mate if they can't they will tell u next best option

Also as chocco said go to Efi to get it tuned they are good with rbs

jet r31 can you please pm me some contact details please.

il go to nissan about an oil pump and a set of pistons tomorrow.

il give spot on performance a call tommorow, thanks for the info booztjunkey

contact details for who?, my mate?, he works out of his garage at home afterhours, during the day he works for the biggest machine shop in adelaide

so does all machine work there, and then brings it home for assembly, I can give you his details via p.m, but remembering its afterhours it takes a while and he usually has a

big waiting list. Very good priced though as no overheads. Having said that, engine builders in a workshop usually take forever aswell..lol

cheers

darren

yeah, you say he does a good job so its worth contacting him and asking what his thoughts are. in any case il be sending my block a long way for machining so may as well get someone experienced to do it. ive been talking to rips for a few weeks working out some options, just waiting on a price from them. not that im after the cheapest option just the best work for the money.

talking to RIPS wont be getting you anywhere near the cheapest option...

seriously...

you have gone above and beyond the guys here and from now on in this build is wallowing out of control

I dont even think you know wats goin on...

a standard engine IS all you want... put the damn thing in and sell it and get a toyota lexen or something

If your head is off and good then its probably worth contacting an importer about a bare long motor or even a half cut and sell off the stuff you don't need

Most places get whole cars, drive them to the container, then chop them up (usually after doing a compression test)

Unless you pay big bucks, you won't get an engine but to as good specs as what Nissan pumps out from the factory where they had guys just building rb's day in day out

You could get a short block and have it inspected, would probably be cheaper too

I tried to get a long block when I first started pulling the engine out, of the 9places I contacted only 1 had ever had a neo motor but didn't have any coming in for atleast 6 months if at all.

Chocco just stay the f**k out of my threads. No one cares what you have to say, and for christs sake learn to read

lol talking like this only makes you a bigger moron champ.

all of this because you know sqaut didly over a simple engine lol

I do hope that your backyard build + the exchange of hands engine lasts no longer

then a 16 year old in bed.

All along you had to do was just listen to the guys that have been there and done

this but no. You could have been up and running again but no. You could have sorted

this all out from the very start but again...no

Ill just sit back and watch this mull away and continue to laugh at your stupidity.

    • Here's one I help build and tuned a decade ago, Garrett  GTX3071R Gen 1, T3 twin scroll 0.83 rear housing. Went from larger 272 cams down to smaller Tomei Poncams to help with the low end. S13 non VCT motor. Car was purpose built for the track, hence low down was the focus. Note the actual dyno chart shows lower boost, however the EBC and boost gauge showed 1.9Bar (Ignore the torque, I was young and didn't know how to set derived torque)  
    • I’m doing some side developments on SR20det S13 engines, its one my hobby cars used it to compare flow capacity of some smaller size wheels. SR20det is one of another JDM legendary engines I'm sure there are plenty of SR enthusiasts on this forum, I will share results some common turbo configurations here. a quick run down of what the car is: Wide body 180sx Type X with black top engine (blue). It has: Stock bottom end Haltech 1500 ECU 5-0 motorsports trigger kit Kelford SR20DET Beehive Spring with Titanium Retainers Kelford Cams SR20DET S13 188-B 268/272 Cams G25-660 Turbocharger in T2 .64 rear housing internally gated ARP Head studs MLS head gasket 1000CC ID injectors Walbro 450L Fuel pump Front mount cooler kit JJR’s 3 inches turbo back exhaust (its too short for the 180sx it had to be extended) Pump 98 fuel Hub Dyno tune So far made 270rwkws at 22psi full boost by 4500RPM. Engine is very knock limited hence a pretty bad looking top end. From previous experiences it seems like SR20dets are happier with bigger size turbine, some thing like a GT30 would make way better top end, but on same time response is lost. It won't be a problem with S15 VCT engines. I'll be testing alternative turbine housing, turbine wheel and possibly dump pipe options for extra flow to resolve the problem and of course E85 would resolve all the issues.            
    • Awesome writeup and details. Thanks for sharing the story so far. I can relate to parts of it with my previous car and some of the issues I had to deal with.
    • Wow the colour matched hard top completely transforms the car. Are there any nice front lip options for the car or is that off the table?
    • Generally yes but for some reason I've been ruthless this time around!  I might even need to do another tip run after the way I've finally been able to hit the delete button on shit I've stepped over, stepped around and tripped over for the past 10 years!
