This weekend I have a fresh rebuilt rb26dett going in bit of work -5 turbos injectors ful hks exhaust and dumps n1 pump oil water ect I blow my old one and decided just to buy a nother one then to build, this motor has not been started used or after rebuild the motor had 60xxx on it before the build.

Once the new motors in everything's al done fluids ect am I able to start the car and drive it, or does it hav to have a run in tube before u can drive it and shit.

Advice needed, tips best way to run it in my self with out f@&king anythkng up

Cheers guys

All engines have to be run in to bed the rings in. If you don't do it properly they might never seal correctly.

Google how to run in a new engine, be amazed there's heaps of ways and no one agrees.

are you running stock ECUs? plan on getting a tune?

stock camshafts? stock pistons/compression?

Personally, I would let engine builder start up first time. Could pressure feed oil, start it up and run for 10-20mins to bed cams in (if new). From then, you know it runs, doesnt leak any fluids and won't go clunk 200m down the road. From there, its up to you how you run everything in.

Ye I got the afm's. Stock ecu ATM

The car has made me broke lol :)

Aftermarket ecu wil come in a few week along with a run in tune and after 1000ks or so a power tune.

What I need to know is once the new engine is in can I drive it til I can afford the tune and ecu ( sensibly )

And if anyone knows the best way to for me to run it in in details please.

Stock ECU means you'll have to use stock injectors and stock MAFs, so keep the boost down very low. The injectors will max out at around 280awkw, but it depends on how dirty they are. No idea what boost that would be on -5s, but probably something like 5psi.

There's many threads about how to run in engine here, so search and you will find. From what i remember, use a cheap/basic dino oil and dont baby it. You probably keep the oil for around 1000kms, then change it out to something good - with filter change.

LOL! It's the fun of it :laugh:

How much power you aiming for?

I probably wouldn't drive it until the ECU is here.

If your not sure how to run it in, just take it to your mechanic, do it once, do it right.

This. Or if you have some way to monitor Air/Fuel ratio. You spend all this money on an engine, the last thing you want to do is damage it. Little things can throw the stock ECU out of whack completely.

as far as run-in goes... I can vouch (but am open to other ideas):

For first start up - Cheap full synthetic oil, magnetic sump plug, new oil filter.

(If with new ECU) Get run-in tune ASAP - car will see boost on the dyno, keep it on the rich side, tuner should keep it running/driving on dyno till you can feel it bed in and AFR is fairly steady/predictable.

0-500kms on street - drive gently-ish, no issues with some boost every so often.

500-1000kms - drop oil, put another fully synthetic, check sump plug for noticeable chunks, new oil filter.

Then final tune.

Aiming for 300 320awkw il be wrapped with for a few months

Hah! Yeah, when the power addiction kicks in!

What mods have you done to urs...

What power you making?

Full rebuilt, Garrett -7's and just the usual, exhaust, air intake etc.

300+ rwkW's.

My two cents

Penrite run in oil

Run for 20 minutes varying revs around 2k

Dump oil and cut open filter and inspect. If all good put new filter and run in oil for 500kms don't thrash it but don't drive like a grandma.

Dump oil and change filter.

Put into your full syn oil, filter and go nuts.

#@RatR32 - that can be done with the stock ecu and with out a tune?

My mates putting my motor in his a good mechanic, just thought I'd get some advice/options from others with rb26's..

I ownd a s15 project for 6yrs knew the works about them could pull it apart and bak in a day lol

I sold it and got the Gtr not doin my research and bang 2nd drive blew the motor.

Cbf doing the overtime to save for a nother engine :(

Cheers :)

      I feel I should re-iterate. The above picture is the only option available in the software and the blurb from HP Tuners I quoted earlier is the only way to add data to it and that's the description they offer as to how to figure it out. The only fields available is the blank box after (Input/ ) and the box right before = Output. Those are the only numbers that can be entered.

      No, your formula is arse backwards. Mine is totally different to yours, and is the one I said was bang on at 50 and 150. I'll put your data into Excel (actually it already is, chart it and fit a linear fit to it, aiming to make it evenly wrong across the whole span. But not now. Other things to do first.

      God damnit. The only option I actually have in the software is the one that is screenshotted. I am glad that I at least got it right... for those two points. Would it actually change anything if I chose/used 80C and 120C as the two points instead? My brain wants to imagine the formula put into HPtuners would be the same equation, otherwise none of this makes sense to me, unless: 1) The formula you put into VCM Scanner/HPTuners is always linear 2) The two points/input pairs are only arbitrary to choose (as the documentation implies) IF the actual scaling of the sensor is linear. then 3) If the scaling is not linear, the two points you choose matter a great deal, because the formula will draw a line between those two points only.

      Nah, that is hella wrong. If I do a simple linear between 150°C (0.407v) and 50°C (2.98v) I get the formula Temperature = -38.8651*voltage + 165.8181 It is perfectly correct at 50 and 150, but it is as much as 20° out in the region of 110°C, because the actual data is significantly non-linear there. It is no more than 4° out down at the lowest temperatures, but is is seriously shit almost everywhere. I cannot believe that the instruction is to do a 2 point linear fit. I would say the method I used previously would have to be better.
