Okay, the below are a list of mods that will be in effect on my RB20DET. I am wondering as to exactly how much the RB20DET block can handle with stock internals before being unreliable and having serious issues.

RB20DET

Sliding Performance's top mount/high mount stainless turbo exhaust manifold

GT3071R

Tial 38mm wastegate set for about 11.603psi/0.8 bar

Plazmaman inlet plenum

FMIC

3" custom exhaust pipe, no cat, hks carbon ti muffler

Splitfire coilpacks

Nismo 555cc fuel injectors for rb20

Greddy Type S boost controller

Walbro 255 fuel pump

optional: cometic metal head gasket/arp studs

other: s13 VSLD 4.11 and custom one piece drive shaft

Will my car (S12) be able to produce approx. 300rwhp/223.88rwkw? Is this good for a couple dyno pulls only? Or is this good for daily? I do not drive hard, but I dont want my engine falling a part in a couple months. I am unable to find exactly how much power/abuse the RB20DET can take.

Thanks.

Hi Draconis

About the easiest way for you to find the answer to this question would be to have a look in the forced induction section at the dyno graphs,or in same section the top rb20 club .there's about 64 pages of people who are making big hp with rb20's relyably its onpage 2 atm.

I was making over 280rwkw for 12 months on a stock bottom end check them out im sure you'll find the answers you want there

Thanks... I read up to page 25 on that particular thread... I saw lots of high numbers so I assumed I could make the power I wanted... but what I am really looking for is how much until the stock bottom end wants to give... that was in addition.

I'm also not using a PFC because none are available up here in the States anymore and as far as I am told, not really anywhere since they are not in production. So I am currently running stock ecu... trying to find a place here in the states to remap my ecu... but am thinking I'm gonna have to buy the unit/send my unit to Australia.

If the motor is in good health, its tuned well, you run good quality oil and keep the oil temp and coolant temp in check, you dont rev it harder then std rev limit, you dont run more then 16psi then there is no reason it wont be very reliable at that power level.

Why not run an AEM etc? Dont they make ecus for RB20?

      Can't you put the pistons to TDC and then do the valve seals? Or will the drop down too far to pull them back up?

      Replacing turbo water line - any recommendations or advice?

      By sunsetR33 · Posted

      One thing I can tell you is, do it properly the first time. If you encounter unexpected problems just let the car sit for a week or two if you have to get some other parts or figure stuff out.  I'd have said go and use as many OEM parts as possible but since you want to change the turbo later on a custom kit is probably the better choice. Since I have no experience with RB25 just compare parts diagrams and images before buying a line kit and it should be easy to see if it has everything you need. Amayama has very good parts diagrams and part number lists, that is what I used a bunch to figure out what I might need. And don't forget to plan ahead and possibly renew other stuff that's easy to get to while you're in there doing the turbo lines. Happy wrenching

      Update 4:   Hi all, good news. Engine is running and all the gaskets and seals seem to be working as intended. No leaks so far, even the JB Weld seems to hold. I flushed out the old coolant a few times and put in fresh coolant, not Nissan stuff, I decided to try the Ravenol Protect FL22, they claim it works for a wide variety of JDM cars and the opinions on it by some people were pretty good. And it has the nice poison green color! And man am I glad I bought a coolant system tester earlier this year, vacuum filling works wonders on this engine. I can definitely recommend this to anyone still doing it the old school way. All you need is compressed air supply. Will have to do a small test drive as soon as I can, I removed the gauge cluster again as the tacho needle was still bouncing around a bit but it was much better than before already.  I also found some cracks on all 4 tires inner and outer sidewalls. Apparently these tires should 't be parked on for extended periods or be kept under 0 degrees during storage, which I did not know. Clearly the previous owner didn't look into those details either, he probably bought them just cause they are cool semi-slicks. I'm just wondering how tf I am supposed to reach 30-80 degree tire temperatures on the public road consistenly, these tires were never going to work for my use case. I'll probably order Continental SportContact7 ones as these are the best allround summer tire available right now and I don't think I'll need anything crazier for now. Do let me know if you have experience with various tires and which ones you recommend.

      Not going to pretend I didn't do a bit of junky work this time around, but mostly due to the fact that some things I am not willing to spend days fixing right now, like wiring. I try to do most things properly the first time around.
