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.

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.

      We have a huge update coming in the next few months, version 5 of Invision will be released. I'm holding off any changes until after this change as I'm not sure what features will be removed or introduced.

      Yeah, plenty of air flow, there is a dedicated path that feeds the air in to the OEM intake tube behind the bumper As for a "tangible effect", maybe, but getting the pod/intake air out of the hot engine bay is worth it psychologically to me, even if it gives no performance difference, so the tangible effect in my Lizard brain saysss yessss  In the end, to me a tangible effect isn't always about performance, sometimes it a sound or a look, or even a...... feeling  Ooga-Chaka Ooga-Ooga Ooga-Chaka Ooga-Ooga Ooga-Chaka Ooga-Ooga Ooga-Chaka Ooga-Ooga

      RB20DE NEO smallbox clutch.

      By Duncan · Posted

      yeah first and reverse is where you will find clutch release issues (whether hydraulic or mechanical) because the difference in revs required is the highest there; particularly changing down from 2nd to 1st when still moving. To be clearer though, it is possible that the clutch release bearing is the wrong height. This is less likely than a hydraulic issue but it is not unheard of when you are mixing and matching

      Replacing turbo water line - any recommendations or advice?

      By jtha7 · Posted

      Hi all, Restoring r33 series 1 rb25det. All the heater hoses were on their way out, have replaced them and put it all back together. After testing I noticed a small leak from behind the head on the actual metal water line to the turbo when cars warm. I tried running a longer hose over it but it kept leaking...   I am about to take the (stock) manifold off again😔 to change the water line does any one have any lines they recommend? I was looking at Aeroflow Turbo Oil & Water Line Set but not sure what everyone else recommends. Car is completely stock but want to upgrade turbo eventually. it looks like ill have to disconnect a lot just to replace these lines so if there's anything else recommended to do please let me know. Thank you in advance!
