here is one of the first 7163 results for the EWG vband housings. its an R35 GTR with 4.1L engine built entirely by SubZero (FR just helped with the turbos). timeslip attached -- watch the launch

EFRs look like great things but fitting long IWG versions to competition cars isn't the same as production ones - particularly if you don't want it to look obviously modified .

This sumbich got to fit 2 IWG efrs!!

I don't know much other than they are the smallest EFRs and appear flow more on paper than the 8374 if they were truly 1+1 which isn't realistic.

Not sure if the guy frequents this site. PPG helical dog, tomei stroker I know for sure. Tomei poncams but unsure of size.

That should shorten it nicely, and external gate specific, the way I like it. :)

I wonder if they plan to do split pulse Vband entry... That would be very trick.

Yup!!

Because I would LOVE to fit a 8374 to my car, but unfortunatly the turbo is too bulky... :(

Yeah that appears to be a problem with some of these EFRs . I can see Geoff and a few others thinking we get these TS IWG turbos to the masses and they want to bitch about packaging . I know they tried really hard to make these things work really well but I ah wonder if a bit more compromise with packaging would be a bit more acceptable to the fast road market . Shortening up those long IW T housings has to affect waste gate performance but would a little less still be streets ahead of the turbocharger competition ?

Hard to please everyone I know cheers A .

^ To be honest, I even have troubles with the EWG versions on evos...

Low mount the turbo dump pipe is too restrictive IMO, and top mount looks like ass.... (not to mention changes the weight distribution of road/race car).

tonba -- man up.. its not that hard to fit these in an evo, especially if you take the a/c out

discopotato - more often than not, the location and bracket for the actuator is the difficult piece to fit- not the length of the turbo. Full-Race has a few different WG brackets to suit many different fitments, that is the real key to making these work, knowing where to position the actuator in each application

^ come on Geoff..

These turbos are an engineers wet dream. But unfortunately, I haven't seen any real world results to show how effective they are. Sure, you have posted results, there are sierra sierra, nemo evo and tilton, but no real world stuff.

My car has A/C, its a street car, and it gets f**king hot in Australia so there is no way I'm getting rid of it. (Its not a race car)

I have seen some really restrictive downpipe designs to try and make these turbo fit in low-mount config. Which to me, kills off the gains that could be obtained. Not to mention having to notch engine mounts. Pain in the butt to fit. :(

I wonder if forward facing is an option? In that case, What I worry about, is running a small radiator..

Ahhhh, Ill find the perfect setup for me one day...

For now, my old FP Black will have to do..

Geoff has a 8374 0.92iwg in his Evo road car.......yeah it gets hot in Aussie, but it's just as hot if not hotter where he lives in Phoenix AZ!

I'm sure he will send you some specs if you ask.

Thanks mate.

I know and understand he runs that turbo. Been following it for a while. As I stated before, top mount just wouldn't work for me, especially if Im interested in more power (Ie 9180.

It still doesn't get around the fact it is a turbo with awkward and inconvenient packaging. I might just have to stick with a Forced Performance turbo, unless there are future options for different compressor / turbine housings...

You guys with your RB's are lucky, as you have much more room over us Evo owners...

One thing I haven't found yet is the suggested maximum angle of inclination. It would be much easier to fit if you could angle the sucker on a 45 degree in some situations, but obviously the drain would be compromised. What is the maximum angle you would suggest Geoff? Taking into account the car will be driving up hills also. :P

I am running my gtx on a 15 degree angle, leaning back in the engine bay to help with packaging on the VQ25det, and it works fine. But there would be a limit...

Does that take into account driving up a hill though? 20* plus say a 30* hill = 50 degrees... Bring on ceramic bearings that don't need lubrication, then we could vertically mount them. :)

    • Thanks, I removed the fuse and the relay from the car and made my own circuit with them to test them with a test bulb.  I will look for the wiring diagram and go from there.
    • Jdm DC2R is also nice for a FF car compared to the regular hatches of the time.
    • Now that the break-in period for both clutch and transmission is nearly over I'd like to give some tips before I forget about everything that happened, also for anyone searching up how to do this job in the future: You will need at least 6 ton jack stands at full extension. I would go as far as to say maybe consider 12 ton jack stands because the height of the transmission + the Harbor Freight hydraulic platform-style transmission jack was enough that it was an absolute PITA getting the transmission out from under the car and back in. The top edge of the bellhousing wants to contact the subframe and oil pan and if you're doing this on the floor forget about trying to lift this transmission off the ground and onto a transmission jack from under the car. Also do not try to use a scissor jack transmission lift. You have to rotate the damn thing in-place on the transmission jack which is hard enough with an adjustable platform and a transmission cradle that will mostly keep the transmission from rolling off the jack but on a scissor lift with a tiny non-adjustable platform? Forget it. Use penetrating oil on the driveshaft bolts. I highly recommend getting a thin 6 point combination (box end + open end) wrench for both the rear driveshaft and front driveshaft and a wrench extension. These bolts are on tight with very little space to work with and those two things together made a massive difference. Even a high torque impact wrench is just the wrong tool for the job here and didn't do what I needed it to do. If your starter bolts aren't seized in place for whatever reason you can in fact snake in a 3/8 inch ratchet + 6 point standard chrome socket up in there and "just" remove the bolts for the starter. Or at least I could. It is entirely by feel, you can barely fit it in, you can barely turn the stupid ratchet, but it is possible. Pull the front pipe/downpipe before you attempt to remove the transmission. In theory you don't have to, in practice just do it.  When pulling the transmission on the way out you don't have to undo all the bolts holding the rear driveshaft to the chassis like the center support bearing and the rear tunnel reinforcement bar but putting the transmission back in I highly recommend doing this because it will let you raise the transmission without constantly dealing with the driveshaft interfering in one way or another. I undid the bottom of the engine mount but I honestly don't know that it helped anything. If you do this make sure you put a towel on the back of the valve cover to keep the engine from smashing all the pipes on the firewall. Once the transmission has been pulled back far enough to clear the dowels you need to twist it in place clockwise if you're sitting behind the transmission. This will rotate the starter down towards the ground. The starter bump seems like it might clear if you twist the transmission the other way but it definitely won't. I have scraped the shit out of my transmission tunnel trying so learn from my mistake. You will need a center punch and an appropriate size drill bit and screw to pull the rear main seal. Then use vice grips and preferably a slide hammer attachment for those vice grips to yank the seal out. Do not let the drill or screw contact any part of the crank and clean the engine carefully after removing the seal to avoid getting metal fragments into the engine. I used a Slide Hammer and Bearing Puller Set, 5 Piece from Harbor Freight to pull the old pilot bearing. The "wet paper towel" trick sucked and just got dirty clutch water everywhere. Buy the tool or borrow it from a friend and save yourself the pain. It comes right out. Mine was very worn compared to the new one and it was starting to show cracks. Soak it in engine oil for a day in case yours has lost all of the oil to the plastic bag it comes in. You may be tempted to get the Nismo aftermarket pilot bearing but local mechanics have told me that they fail prematurely and if they do fail they do far more damage than a failed OEM pilot bushing. I mentioned this before but the Super Coppermix Twin clutch friction disks are in fact directional. The subtle coning of the fingers in both cases should be facing towards the center of the hub. So the coning on the rearmost disk closest to the pressure plate should go towards the engine, and the one closest to the flywheel should be flipped the other way. Otherwise when you torque down the pressure plate it will be warped and if you attempt to drive it like this it will make a very nasty grinding noise. Also, there is in fact an orientation to the washers for the pressure plate if you don't want to damage the anodizing. Rounded side of the washer faces the pressure plate. The flat side faces the bolt head. Pulling the transmission from the transfer case you need to be extremely careful with the shift cover plate. This part is discontinued. Try your best to avoid damaging the mating surfaces or breaking the pry points. I used a dead blow rubber hammer after removing the bolts to smack it sideways to slide it off the RTV the previous mechanic applied. I recommend using gasket dressing on the OEM paper gasket to try and keep the ATF from leaking out of that surface which seems to be a perpetual problem. Undoing the shifter rod end is an absolute PITA. Get a set of roll pin punches. Those are mandatory for this. Also I strongly, strongly recommend getting a palm nailer that will fit your roll pin punch. Also, put a clean (emphasis on clean) towel wrapped around the back end of the roll pin to keep it from shooting into the transfer case so you can spend a good hour or two with a magnet on a stick getting it out. Do not damage the shifter rod end either because those are discontinued as well. Do not use aftermarket flywheel bolts. Or if you do, make sure they are exactly the same dimensions as OEM before you go to install them. I have seen people mention that they got the wrong bolts and it meant having to do the job again. High torque impact wrench makes removal easy. I used some combination of a pry bar and flathead screwdriver to keep the flywheel from turning but consider just buying a proper flywheel lock instead. Just buy the OS Giken clutch alignment tool from RHDJapan. I hated the plastic alignment tool and you will never be confident this thing will work as intended. Don't forget to install the Nismo provided clutch fork boot. Otherwise it will make unearthly noises when you press the clutch pedal as it says on the little installation sheet in Japanese. Also, on both initial disassembly and assembly you must follow torque sequence for the pressure plate bolts. For some reason the Nismo directions tell you to put in the smaller 3 bolts last. I would not do this. Fully insert and thread those bolts to the end first, then tighten the other larger pressure plate bolts according to torque sequence. Then at the end you can also torque these 3 smaller bolts. Doing it the other way can cause these bolts to bind and the whole thing won't fit as it should. Hope this helps someone out there.
