Yes, that is my plan as well.

The stock motor will be slower then the one I had. That was a 236kw/350nm NA engine.

Do the fit and tune at 15psi with exhaust and cam gears and the stock 26 should make about 250rwkw and 500+nm which will easy shit on what ever NA you pulled out

Sweet.

Can someone school me on the Kinugawa turbos? They have three kits on Ebay that I fancy.

Tanked to local turbo man, he claimed 500+ from stock turbos with steel turbine.

your local turbo man is full o shit

and yea a tunes stock motor will wipe the floor with a na

He also questioned why I bothered putting the old worn out and unreliable RB engine in a BMW instead of a M3 og M5 engine. He had used insane amount on his engine and it was never any good.

My plan is to make it reliable. A rebuild now, proper oil system, poper oil ventilation, good turbos and there will be some years before she needs to be taken care of again I hope. Not going to run insane hp anyway.

As piggaz said. Injectors aren't just about their ability to flow fuel. It's about how well they work at low rpm/small pulsewidths. The newer Bosch injectors shit all over older Sards/densos etc in both departments.

Cheers

Did get the engine yesterday, so I have been wrenching a bit today. Tested in the car and removed the oilpan to get the diffhousing cut off.

If the result is that I just can't get room for the twins, what will be the most responsive single turbo option?

Ditch the n1 oil pump no matter what gears are in it.

Go Tomei/HKS/Jun every time - in that order.

Get a trust sump extension - they wing the sump so its out to the left/right.

-5's will be fine with a good set of CAMs/Gears.

I had this with standard internals - 345KW at all 4's no issues until i dropped a big end bearing due to oil pump failure.

Tomei is best and JUN is not that good? Have a JUN pump on hand now.

Tomie pump is externally pressure adjustable, this is the reason i only like to run them, they are only a little bit more in price to the other brand name full pumps.

There is a plug on one side, on the outside that can be removed and you can adjust the oil pressure as needed.

Other pumps have it hanging on the inside of the sump, if you want to play with it you need to get the sump off which in most cases is a engine out job.

I did my oil returns to 10.5mm in the block and head, i also added breathers to my sump and used a gated baffel 9lt sump extension and built my own tomie style windage tray to direct returning oil to the pickup area.

    • Hi. Sry iam not a mechanic and iam not at the car atm so i dont know 100% but they told they measure those and even try to change those. AFM they have two. Coils are new a they have my old one too. Plugs too. ECU...we have 25 NEO stock and Nistune 25 NEO.   But i dont know if any one those could be the problem and why/if/what can cause this, Only thing they did not check is fuel...but that walbro 255 is new(like 1,5 years)... That fuel pressure gauge idk...but i let them know Any suggestions?   EDIT: how can they know if it is like you say he ECU pull power when it reaches a specific boost level that is too high? Tha car has boost controler
    • Can you clarify what you mean by boost cut, do you mean it misfires both when under load (driving) and when stationary and out of gear? Or does the ECU pull power when it reaches a specific boost level that is too high (boost control issue)? Does it occur at idle with no throttle? When you say "the ECU is OK", what ECU is it and why do you think it is OK? Have you used the NEO ECU, and if so do you have a MAP sensor attached? Same for the AFM, why do you think it is OK? Do you have any way to put a fuel pressure gauge on it (even just a mechanical one between the fuel filter and fuel rail)?
    • Hi.. Just another problem. So maybe you can help. I(my mechanic) done swap from my RB20DE NEO to RB25DET NEO. Everything is OK but we have a boost cut. Coils/Plugs are ok...AFM is ok. ECU is ok. I have Walbro 255 but it "changed" sound few months ago(you can hear it ouside) you did not hear that when it was new(maybe faulty?) Sooo...what now? What can cause this boost cut? It is even when you standing still...
