To answer your question on the CXRacing kit -- I have the full s13/rb25 T70 kit. I had to make some adjustments to get it to fit on the studs, but otherwise it "just worked", wastegate, dump pipe, and all. That cheap turbo was pretty laggy, and I kept it at 10psi, but it worked. Didn't make basically any power until 5000rpm, and it made about 230whp at 7psi, so... not bad. Coming off a failed OEM turbo, this was a cheap step towards my idea setup, with some temporary compromises, but allowed me to get the car running and driving for a few years while I saved up, fixed, and planned. Of note: the V-band flanges and clamps included will definitely leak a little. The flanges that have the lip on the inside like vibrant or garrett (instead of completely flat) wouldn't have this problem, nor are they compatible with the BW turbo flange. Since then, I've swapped to a turbosmart 38mm gate (bolted right on, only for peace of mind), modified the dump pipe to recirculate the wastegate, and swapped to a G30-770 w/ T4 flange. Much to my surprise, it just worked, and I drove it on the same tune for about a year. Strangely, I didn't have to tweak the wastegate duty at all... until we turned it up later. It's now making 400whp at 20psi, but still pretty laggy, not really making full power until about the same 5000rpm. Noticeably more responsive than the T70, but it's way off where it should be. I'm pretty sure there's some problem somewhere, I just haven't found it. Maybe the manifold just naturally makes turbos lazy, or maybe there's an exhaust leak, I dunno; something. I think my next step is getting a twin-scroll manifold, and redoing the downpipe w/ better V-Band flanges that don't leak. So... is the CXRacing kit a cheap way to make some power and get a working car? yes. BUT you will have a laggy setup. Probably won't notice a difference on an S300, but it's definitely a way to save money. I don't regret my choices, because it was a 1000$ option all-in to get a running driving car that allowed me to upgrade piece-by-piece as necessary. Even if I completely replace the whole thing, the value of having a working car for many years was worth it.

this 👆 .. first hand review.. thanks for the comment!

Lol I remember literally laughing out loud back when I was trying to build a rb engine before you could find much of anything at all parts or information wise but I had got ahold of someone at tomei in Japan who could speak English but unfortunately he wasn't knolagable as far as being able to answer my questions or recommending the parts I needed but back then we had paper catalogs (ya I'm old lol) but after 25 minutes of explaining the goals of the engine ECT I asked what all do I need to do what I want but also keep it together... The guy who was translateing to me after alot of back and forth with the engineering guy said" ok go to page xxx ok now go half way down.. ok you need everything from there until the end of the next page" lol and he was very serious lol god bless the internet

awesome! good luck with it

Check out the rb30 crank collar. 😮 We have been replacing them since early 90s. The other is you need a decent balancer to be reliable if you rev it. Don’t run less than one front and rear restrictor. Run dual 1-1.3s depending on the pump. If you circuit scavenge pump.

She's coming along nice...def my favorite.

Some very good info. I have an r33 gts25t I'm having idling issues at the moment in the process of changing to 550cc injectors and 255lph fuel pump. That oil drain sounds like a good idea though. Keep up the good work. 👍

Extended baffled sump helps the most w drifting, catch can returned to the sump aswel. I run a 30/25 pushing 594whp and everything has been done as mentioned. Running a borgwarner s300sx. Next time I wouldnt go that turbo and new tech to bring it on 500rpm earlier. Also running 272 kelfords & upgraded springs. Trigger kit is a must. Hope this helps anyone w info on what to do

Love the video, applies to all RB'S. I want to add one thing, 10w60 full synthetic oil! Rb's love oil pressure and it definitely helps the longevity for alot of the bottom end. Just my 2 cents!

another interesting fact, Borg Warner and holset are notorious for maintaining the turbo diesel exhaust wheel tech,from first hand experience they are horrible for bringing boost on early and making good power compared to new turbo tech

Hi Octane offers a plug and play for the head drain set up. The drain plug uses existing thread holes on the head and that’s it. Hope this helps anyone.

Just grabbed an r31 with an rb25de in it so you know if I would be able to put a turbo on the de without a lot of headaches or should I just leave it na

thanks.. yes. the head definitely has to come off (or engine out of car). you have to knock out a freeze plug, then drill and tap the back of the head

Nice video. Major advantage of the top mount is access to the turbo, I have found. If you ever swap the BW for a less laggy model, you'll be happy to have gone top mount. 😁 Any plans on getting a more modern trigger kit?
