going price for short / long block assembly

[StricNyne]

whats the prices people have been paying for long blocks and short blocks ? i was quoted 300 for a short block and 1k for a long block from oilpan to valvecovers, if that a fair and competive price ? i was gunna do short block for now, then take head to machine shop and have them play with it and check everything out, but money is sooo tight, if someone coud help me i would give them rb parts for their labor hehe also what have people paid to get a head checkes and reassembled?

[rustbucket]

What kind of RB? I think the average long block 25, with uncut wiring is $1500 and maybe a 20 is $1000-$1200 (not too sure about the 20).

Its probably cheaper to buy the entier motorset, that is if your going to get a RB25 cause the transmission is hard to come by and it will be cheaper in the long run.

[tjmhillz]

he has the 25 already

ASSEMBLY

$1000 is about right. I paid about $1500 for mine but I had machine work done as well (~$300 for block hone, etc.).

Around here, expect to pay about $400 for them to tear a head apart...less obviously to just "check it over".

[StricNyne]

yeah its just assembly, i have worked on varius projects, but i am a lil skeptical about assembling my own long block, i mean the manifolds are one thing but when u got something making 7000 rotations per min yer might wanna have a professional have his say

[rotorimp]

It is actually not rotating that fast--RPM's is a misnomer it is actually 7000 sparks per min your RPM gage is counting the sparks not the revolutions. That is why it appears Diesels are rotating slower but a diesel is counting the revolutions because there is no spark to count.

[kjlindgr]

^^^ why do you post crap like this?

And how does the RB set off the Ignition???Through the CAS, which is mounted to the Camshaft, which is turned by the timing belt which is turned by th Crankshaft.

[StricNyne]

cough..powned...cough seriously i think i am gunna have a pro do it there is a local guy who is very reputable and for 1k and the time he spends doing it it gives me a chance to focus on other things

[wawazat8402]

you might hit up DragDriftAutoX. I think he usually has a long block or two. I was quoted 800 shipped for an RB25 with no manifold. just the block, head and internals. That was shipped from Washington state to an Oklahoma business address.

[StricNyne]

wow including water pump, and oil pan and everything ?

[StricNyne]

u mean dont mean for sale right ?

[wawazat8402]

My understanding was oil pan to valvecovers but nothing else. No manifolds, sensors, etc.

cyber mechanic/idiot

[rotorimp]

Cyber mechanic?

Anyone that thinks that the crank is turning 5000 RPM just because the TACH is reading 5000 RPM -->Needs to attend a BASIC engine theory class or better yet use the most powerful research tool in the world that your attached to right now.

[rotorimp]

The Ecu derives the RPM from the CAS (On RB's)--But seriously think about-the cams rotation speed compared to the cranks. this is coil on plug set up.

Most motors that use a coil--the tach signal comes directly off of the tach.

sparks per minute = RPM

Before anyone replies with something retarded PLEASE just open up any browser and find out for yourself

[StricNyne]

all of that is irrevelant, i am not gunna say what i want to say, but i will simply say that that does the least in saying how much long block assembly is

[rotorimp]

Sorry about the thread jack---Unless you can find a local hook up just for the long block ---the cheapest I have seen is 1300 for a R33 Rb25 with AUTOMATIC trans (this is a whole motor set) Nico sponsor

[StricNyne]

nonono lol, i already got the longblock, ineed it put togeather as in motor is apart

[rotorimp]

If people bring me a motor and want it put back to spec I charge $500+ for my labor + parts + machine work. double that plus for a full time shop.

I just put together a BUILT KA $600+ for machine work $3000+ for parts $500 for labor (this was friend price)

There are soo many variables to that question --- it is hard even to put a average number on it.

It depends if everything is in specIt depends if you provide the partsIt depends if the motor needs machine work

I have built motors for a few hundred dollars to motors that cost thousands to put together.

Remember ---You get what you pay for--Cheapest Is usually not the best.Every motor I put together is to the .0001 and blue printed to the performance advantage. every surface is perfect. I assemble the motors at the temperature my torque wrenches were calibrated at. precision costs money. Most people can not duplicate the exactness of Nissan. So a engine build will cost more than a long block from a engine supplier especially if money is tight.

[StricNyne]

i have every part(beairins, mainbolts, headgasket, headstuds, wiseco pistons, rings, gasket kit) its already been balanced just need 2 be put togeather

[rotorimp]

How do you know the bearings are the right size? Nissan uses select fit bearings unless you are going after market. Are you putting stock size pistons or are you going 10-- 20 over? did you have a machine shop balance it. Putting the motor together is the easy part--getting everything into spec is the most time consuming thing. If everything is indeed in spec then you should be able to get it put together pretty cheap.

[StricNyne]

ya everything is in spec it is rdy to be assembled, and its been balanced by machine shop

[rotorimp]

Is the machine shop that did the other work give you the 300$ short block estimate? Why did the motor come apart in the first place?

[StricNyne]

came apart because fo 3 blown pistons, decided to do rb26 crank and larger pistons, block was bored for larger pistons, and the crank is currntly installed no i actually heard around 250 ish but the guy i currently think i might go with wants 300

[kjlindgr]

Vote to ban rotorimp for the blatant lies he's trying to pass as truth in his jacking of this thread.

[rotorimp]

blatant lies---? RRRight---anyway ----best of luck StricNyne. Motor assembly takes allot ot time, knowledge, patience and the right tools. My motors are built right and make allot of power. It doesn't hurt anyone to crack a book a learn some new stuff. Instead of paying someone to assemble your motor--Do it yourself. work clean--spend the money you would pay someone and buy a couple torque wrenches and micrometers. make sure who ever you have do the motor you see some of the work that they have done and make sure they have some kind of a warranty

Check out one of my recent motors: zerothread/176176

[StricNyne]

i am always down to learn something just i would be doing this primarily my self and i cant afford to mess this up hehehe, i honestly rather do this my self, but idk i am not not rich, but i think its worth it to pay and get it done
