- Here’s a quick, basic rundown on the differences between a stock Cooper S turbo, RPM Powered R300 and an EBay Rev9 6+6 46.5mm turbo. This applies to 2nd gen Mini’s, R55-R61

I work at a dealership. That stock cooper s turbo looked EXACTLY like mine. Loose wastegate and all. It’s better to get a second hand decent mileage turbo, slap her on there, KEEP YOUR OLD ONE, buy an impeller end actuator kit, it’s actually not that hard and by the end of the day you’ll have a reconditioned turbo.
Takes time, but if you’re on a budget it’s a good way to keep a turbo in your back pocket for back up.
That being said, if you’re trying to make big power. The R300 or EBay turbo will get you that power more reliably as I’m sure OP of the video stated.
Great vid my guy
Thank you! 🫡
Hi there , this looks like the best video ive seen on these turbos , im new to turbos , can you tell me if its ok to have actuator rod to lever play and adjust out . Im getting over boost !! replaced and tested both electronic actuators for waste gate and blow off with peugeot software. Can a worn acutator lever pivot point if it has 2mm- 3mm movement cause over boosting ??? thinking of replacing the turbo but it spools up fine has plenty of boost and waste gate is holding pressure. your thoughts would be great
If it gets stuck maybe possible, but usually underboost is more common. Check the angle of the pivot, maybe lower the adjustment towards the downpipe for lowering boost
Exactly what I was going to comment about being the best explanation video on the turbos for the r56 mini. I’m in the uk and I’m thinking about a r56 n14 mini, wanting to buy parts before I’ve picked the car up so I’m readyyyyy 😂 I’ve been a vag (vw/Audi) guy for a while but wanting a mini to play with. I’d be happy with 300-350bhp.
@@BlaxJakx people say to stay away from the n14 but at the end of the day it’s the best engine for power. Make sure you keep up on the maintenance first and highly likely timing chain
The wastegate on that factory unit could be repaired for not too much money if you were on an ultra budget. A shim kit would restore it back to new.
Honestly, the factory unit are practically bulletproof and serve their purpose well. Weak link is the diverter valve, but that's a problem with all modern day turbos.
That eBay unit, you get what you pay for. Don't be surprised if the housing cracks, and you develop an internal leak. I had one of those eBay specials take me for a nice diagnostic ride on a customer car once. Heavy smoke at start up, the exhaust housing cracked, and was leaking coolant into the exhaust. 🤦♂️😭
I bet that housing leaking coolant into the exhaust housing was a fun one. On another S turbo I just completed installing the Wastegate flapper and arm
You reported the size of the stock and Rev9 turbos, curious what the size of the RPM R300 is?
I know the dimensions but don’t want to spoil everything as people love to copy and paste. I’ll just say Compressor dimension is pretty much stock JCW and inducer is let’s say a couple mill bigger than stock JCW size
Exhaust wheel is key and not too big of a compressor wheel
Appreciate the info! Thanks for the reply@@zevisgarage
What about a JCW turbo? I have a S and the JCW is supposed to be bigger? I am looking for a turbo upgrade on my mini I have full bolt ons and upgraded my intercooler, would it be best for a Used JCW turbo upgrade or something else?
JCW is a nice upgrade compared to the S, but I can’t get over how R300 performs compared to both
Is your turbo smart actuator blowing off at lower rpm??
No
So I've got a manic tuned n18 cooper s. Full bolt ons and catless. I can no longer get a Manic tune/ re-tune/ stage 2 tune since the company closed, but I love the tune, I've had it for 4+ years and the little car flies.
If I replace my turbo can I just slap a JCW on there without a re tune? Or should I just be looking for another S model. And would I would I be able to gain anything with the JCW turbo going that way?
You should still be safe enough to run the same tune with JCW turbo
In fact, it might be a stage 2 I'm not sure. My tuner, years ago, didn't want to disclose much info as Manic was in the process of going out of business when he did the tune. Not even sure I was supposed to be getting it at that point due to legal reasons. I get max 19psi max, but have seen 20psi during good conditions so not sure if that would let you know what stage it is..
@@zevisgarage Thank you for the quick response. I'll check out some more of your mini content!
@@zevisgarage Do you think there would be any benefit to it? Or so minimal it might just be safe to keep an S turbo since I know everything runs correctly as is
@@jrh1704 definitely worth it, it shouldn’t be a big enough difference to hurt anything, but it’s still enough that you will notice it’s added performance over the S turbo. The S turbo runs out of breath pretty quickly
How reliable would you say the rev9 turbo is? Thinking about getting one
Should be reliable, but I’m not impressed with the performance. After running and testing the R300 on several cars I would never run the rev9 again, nor 95% of other turbos available for the Mini’s
@@zevisgarage hey would you choose jmtc s42 turbo over rev9? Also what else do i need to replace if i got that route too make new turbos fit and work well?
@@andyzs2k I would, but longevity on both probably wouldn’t be super high. If you do pulls once in a while it’s fine, but if you expect lots of track and canyons something like the r300 would be better
@@zevisgarage so which one would you pick the jmtc or the rev9?
@@andyzs2k JMTC I suppose
Clearly the r300 is the best turbo, but what do you think what size compressor wheel does it has? 43/56mm or bigger?
Likely around there
@@zevisgarage Have you thought about trying the Mamba turbo? It looks to be the best quality bigger turbo under a grand.
@@Raymo2u mamba doesn’t interest me, they are pretty cheap quality parts
@@zevisgarage
So glade I found your channel
No on this particular vaccume controlled actuator
At you running the bottom port to the fact controller
Little confused with this one everything backward🙃
I get just vent but say I want to control more a 3 port needs to be rigged up correct?
@@single_cam9199 just factory actuator setup, no aftermarket electronic boost controller or anything just factory ECU control
I’ll be running 3 port on my car with the R400 kit
I need one
What kind you looking for?
I m really know I Need to upgrade turbo K04 stigan or rev 9 it’s be the same quality to the oem Wagner
Neither turbo is OEM quality. The R300 is the only turbo I’ve seen that matches and exceeds it
can these bad boys be put on a fbo upgraded fuel pumps stock motor mini
I ran stock fueling stock internals with all of these turbos
Original for sure
Nah too slow
@@zevisgarage don’t care, I’m not a race driver professional disputing any title, just want it reliable and silent and efficient
@@cmtetaboaco the r300 in the video would do that. While having more power, and flowing better. The stock turbo bottle necks pretty quickly
What about the TTE300?
R300 spools faster, and it also has anti surge
With the right settings, k04 is much more productive than k03s (r300)
Not in my opinion. Unless engine is 100% built something like the r300 is more than adequate
@@zevisgarage I have already K04. Larger compressor wheel, more power you will get.
Soon I will get stage 3 and I will write back. Is r300 the same as K03s?
@@Mymini1991 yes more peak power but with the lag you can get with the bigger turbos it’s just not worth it. I know because I had a bigger one and went down to the r300
@@Mymini1991A K03 is perfect for 99% of the vehicles on the road today. K04's are for big HP applications that require significant modding and tuning. Basically making the car much less reliable and more of a hassle to daily drive.
Bigger doesn't always mean better. It's all about balance and what you are looking to achieve with your build.
For the price of the RPM you Gould get a GTX2860r or 2867r
Not with manifold and such. Plus there are better options that those nowadays, and for a stock engine R300 will out perform those, mainly with response. The R300 is so damn good on a stock engine stock fueling car, torque at just about any RPM
@@zevisgarage adaptor plates now are pretty cheap to mate it to the manifold to save money over a custom manifold. I've got the GTX2860r and it spools a little later but tbh it's not a massive issue. If you're hitting the gas you're probably around 3k upwards anyway so a 1500 spool means nothing. If you're chasing any sort of power on stock rods and pistons even the R300 you've got high chances of blowing it. Forge and then go big 😉
@@clementspeedshop yeah I’ll be going big soon, just collecting parts right now
@clementspeedshop hey man how did you find a solution for Bov with that turbo? I’m currently trying to put one on mine (have a few project cars) Gtx happens to be on my shelf as a spare. Would love to talk to you about your build!
Has anyone used stigan turbos?
I have not, them and Kinugawa have a few interesting spec ones I’d be interested in
JMTC s42
R300 over the S42 all day
@@zevisgarage is the s42 that bad, r300 is out of my budget.
@@gratefulthreadsupholstery the performance of it is great, the longevity of it is very weak. I’ve had Wastegate a fail, turbine shafts break, etc
Would you say s42 is more reliable than rev9? Cant decide on which one to get. Dont have the funds for r300. My stock turbo is only making 16-17psi on stage 2 mario tune from 1st gear to 4th then from 5th to 6th gear it goes up slightly to 19-20psi
@@gratefulthreadsupholstery I got the refurbished s42 and haven’t had any problems on stage 2

Ty. I just ordered "s2" clutch and then hopefully will be joining the r300 club. Vids on the way since the install?
@@kreevey33 install video should be coming pretty soon. I have some videos of me drifting around that will probably come right after that with the R300
