To re-surface the manifold, you will need two jigs holding both surfaces dead solid and flat on a milling machine before running surface cutter over them. I've got those jigs to for my Brae high mount years ago, that should be able to hold yours. If you can't get them done locally we are able to take your job.

The roller dyno works fine in setting up the correct ecu parameters. Because the data output do depend on the rolling object, when comes to preciseness for developments and research its not that accurate. As the firmness of the tire, the size of wheels, position of where the wheels are parked and the tension of strap can all affect its power output. When shaping turbo wheels for very specific applications. the mm in alterations will slightly alter output and we must to be able to compare those changes. Thas is what a hub dyno is good at, without variances the rolling object, the output is extremely consistent and accurate. There are specific HP determination equation for different regions, assume the same equation is used, with test vehicles perfectly set, the HP reading between dynos should be very similar. There are many other variants that could alter the performance of a engine, which I have specifically picked and tested those areas using RB engines, data has been recorded and could be found on index page 1.

the chras about the same size. R34 has a larger rear housing.

Older Bush bearing high flows requires the sump oil restrictor drilled. While the new Ceramic ball bearing system is designed to work with factory oil supply system and provide supreme throttle response. This are used on all M35 high flows that I currently do. Regarding to transmission slam into gears, I've been into Scotty's car and it wasn't anything like it, hence the earlier question about ecu and transmission.

How does my post has any thing to do with you or Scotty? LoL, so lets get it straight, I just spent 10G on a car with thousands dollars of your work which I drove on daily bases that doesn't feel right, and you are silencing me from asking genuine questions. I'm a new owner to two M35s Stageas, I've spent $35G so far in my research and developments getting the right turbo configurations for OEM housings as well as a low oil consumption bearing assembly, I see no one else is doing that for this community. So sorry to ask stupid questions. There are hundreds of people like my self searching for answers, it might be worth while giving informative replies. By the way since CBB turbos worked for you 8 years ago, I will keep those balls rolling.

Well, I need the job done, building M35 test rig two now. Also whats in that transmission? Its got a very hard and clunky feel every time it shifts gear.

LoL fkn stock air box. You AFR might not be the same.

Yes idle on ceramic balls now, with factory oil flow and pressure. Funny Test car throw two con rods out of engine block and knocked out a section of transmission during 1st to 2nd shift at 40% throttle on 9psi. I'm quite interested to find out what that might be corresponded to.

For evaluations, I usually stick CBB catridges into turbos with tinny housings and run high boost, trial its reliability under extreme heat and back pressure. That 287rwkws run is with Ceramic ball bearings. it starting to surge light throttle in 3rd and 4th unless WOT, very loud on dyno. 20psi by 3500RPM 4th gear manual on a RB25det is about where the surging point is. Because the 21U is so small, I couldn't feel any differences in down low throttle response.

Depending on how free flow every thing are. If you have a cheap cooler with an 3 inches turbo back it will be running at lower boost. Far as engineering concern, this turbo is made to hold upper rev boost and getting close to 300rwkws as possible internally gated.

in a very free flow system it should be getting around the 18psi region.

Easiest way to check a turbo is to have a feel of turbo shaft, there should be under a mm side wise and nothing in and out.

Here you go. factory M35 with Blitz cooler and 3 inches turbo back exhaust. 162awkws on P98 fuel.

Additional updates. This is our M35RV-1 high flow running duel ceramic ball bearing cartridges. This turbocharger is built for maximum response, happy to run OEM boost levels on OEM ECU, and matching factory drive ability with bit more power. It will be topping out towards 240awkws region using an high pressure actuator. So far dynosheet below shown 200awkws @ 13psi with fuel, ecu, cooler and exhaust mods. factory actuator not holding boost. Ps: For the best possible throttle response and off boost driving ability working with OEM auto, and low oil flow requirements. All of our M35 high flows will be running thrust less duel ceramic ball bearing cartridges.

Just Picked up another Stagea. Fully stock, I will be using it to do some evaluations based on the RV1 CBB high flow. and I will pass on all details and parts used in terms of modifications as project move along.

The seals are just stainless steel Clips. they don't ware unless there is an abnormal amount of shaft movements. That is also indicating the bearings needs replacing. If it is one of their Xtreme BB using OEM bearing housing then only they can have it repaired, or it might be cheaper to re-highflow. Alternatively if it is a T3x bush bearing center, depending on how bad the shaft and wheels are, you can simply replace the bearings and seals, we can supply the bearing kit at if required PM for details.

Here you go. Our Standard OP6 high flow profile. Internally and externally gated, All on E85 fuel Rebuilt engine R33 engine with stock cams, and stock inlet manifold. The most it made externally gated was 376rwkws The most it made internally gated was 324rwkws This result is more then 2 years old now. I can make it blow over 400rwkws today with similar response. When using my thread, page 1 is an index page, Ctrl+F for searching criteria and that should take you to the corresponding page. It contains heaps of information in relation to turbocharger development as well as how and what supporting mods do to power curve.

Get a 600x300x100mm front mount first, send us the turbo for another high flow if its not making enough power.

This will be the final update on the M35 Stagea OEM turbocharger high flows. The Ball bearing RV5 have made a peek of 291awkws @ 22psi on E85 fuel, that is also happy to hold 21psi as minimum base pressure. For any more power that is boost controllable this car needs a much larger exhaust housing or external gate. Dyno shown 27psi mid range and 22psi of where peek power is made. The mid range boost was pumped using an EBC, to increase mid range torque. Blue line is with converter unlocked and red is with convert locked. Far as drive ability concern, it has excellent throttle response working with OEM auto in D model, and pulls hard in WTO.

Yes it is. But we don't BB 21U high flows. They are already so responsive to a point any better will cause the turbo to surge.

ATR43's BB cartridges has been out for a while now. Except it didn't make much of a differences working with the older turbine end. Using the new SAT turbine there is a noticeable improvement on drive ability. Turbine side looks like:

Other thing worth mentioning is the Ball bearing cartridges works extremely well with the new SAT turbine including the current ATR45SAT, G3, SS2 and OP6 high flows. That have made a very noticeable difference to throttle response making the car feels much "lighter" on and off throttle. Highly recommended for street driving machines.

Needs to be 100 cell 5 inches cat, no cat with exhaust Tee will give you the best result.
