  1. Thought i would throw this up for peoples interest. I have been working on a fairly basic build of my R33GTR (in the builds section). Due to budget reasons I decided to try one of the BW SX-E S300 8376 turbos. Yes I know 8374EFRs are what everyone recommends but budget did not allow it at the time of purchase. There is very little info on the BW SX-E turbo stuff being used on RBs so thought I would share my results to date. Build: Completely stock RB26 Link G4+ (inc Fuel press, Oil press and Fuel temp sensors and controlling boost) BW SX-E S300 8376 (.91 T4 divided A/R rear) Sinco T4 Divided manifold Turbosmart 60mm WG Seimens 875cc injectors on aftermarket rail Aeromotive FP reg Walbro 460 with mandatory rewire 4" Dump off turbo then into 3.5" exhaust (no cat) R35 Coils Platinum Racing/Franlkin Engineering Trigger kit Stock intercooler Car is running 98 pump (E85 is not an option for me due to lack of availability sadly) The car has just been on the dyno and results were: 305KW ATW on 14PSI (Wastegate spring pressure) 385KW ATW on 20PSI We limited the boost to 20PSI due to the engine being completely stock. While the power is solid the turbo is pretty lazy on this setup, I was hoping it would be a little better but it was always going to be a dice roll. We discovered a fairly significant boost leak from the manifold which may have hurt response slightly. However it is looking like this setup may be a bit big for a completely stock RB26. Perhaps an RB30 or a 26 with head work/cams etc would wake it up a bit earlier. We have not played with cam gears as yet and there looks to be a smaller rear housing option (.83) I can also try otherwise I will have to switch to an EFR to get the response I am after. Results:

    So go the last few small things buttoned up and got the car out o the shed for a wash after 4 months. Then off to the dyno. Some interesting results. The car made 305kw ATW on wastegate pressure (14 psi) and 385kw ATW on 20psi. While the power is solid, the response is not as great as I was hoping. It has always been hard to get any solid data on anywone using these SX-E turbos on RBs so was a bit of a punt to try one. I found a fairly significant boost leak at the inlet manifold where it looks like i have damaged a gasket which wont be helping but overall it looks like this turbo could be sized a little too big for a stock Rb26 on 98 (E85 not an option for me as too hard to get sadly). I will get the boost leak sorted and we haven't played with cam gears to see if that will wake it up a bit. I have seen some smaller housing options available in the USA which may help also but it is looking likely i will change to an EFR to gain back some response. Dyno graph for those interested.

    Good push over the weekend, got most of the final bits sorted. Had to relocate Oil filter block as the new radiator is too thick and was hitting it in the origination location I chose. Managed to squeeze it in the space near the transfer case which in hind site is a better spot anyway. Purchased a new Koyorad radiator. Unfortunately the one that was supplied did not include the sensor bung for the thermo fan which is located down near the lower hose exit. There was none of the other versions available instock so tapped the thermo sensor into a radiator sensor adapter and placed it in the lower hose. Painted radiator and installed Relocated Bosch air temp sensor into the cooler pipe Completed all the wiring. This included wiring up the crank trigger sensors, oil and fuel pressure sensors and the air intake sensor. Added head shield cover to exhaust rear housing and installed boost control solenoid which will be run by the G4+. Engine bay pretty much sorted now. Plugged in the G4+ and configured crank triggers and other required settings. Engine fired up nicely once timing was all adjusted. Warmed it up and checked for leaks, small coolant and fuel leak needed to be sorted but other wise all good. Still have to tidy a few small things and install new fuel pump setup and then off to the dyno. 2018-11-24 15.44.52.mp4

    Made up some ducting for the oil cooler. It is fed through the air vent in the indicator surround.

    Got some more work done. Turbo and wastegate installed for hopefully the last time (wont be). Heat wrapped dump pipe. New plugs and NZEFI R35 coil kit installed. Fast response IAT sensor fitted. I may move this to the intercooler pipe in the future.

    Bit more progress... Got the Grex remote oil filter unit mounted. I didnt want it up high in the engine bay so found a spot that seems to work Ok. (Dont worry about the dented filter it was just for mock up purposes) Lines back to the block. I wrapped the lines in plastic conduit to give some extra protection against rubbing etc. Oil cooler installed. I will probably make some ducting for this. Lines back to the oil filter block finished off. Nuke B/V installed. It is a direct fit onto the OEM gtr hard piping piping making things nice and easy. Oil catch can breather finished off. I want to try and keep as much oil smell out of the cabin as possible so hopefully this will help.

    Cheers bro, yea I would like to do that and some drop in cams also. Will see how the budget goes...

    Hope so man, fingers crossed it is not a dog response wise.

    I removed intake manifold so i could give it a tidy up and it would make life easier installing remote oil filter bracket and making fuel lines etc. Decided to go with Aeromotive fuel pressure reg, added a pressure sensor so link can monitor things. Nuke fuel filter Made up some brackets to hole the reg and filter. Fuel rail and injector installed and fuel lines made up I sandblasted the inlet manifold as the original paint was a bit flakey. Looked at the idea of leaving it raw finish. But in the end opted to repaint it satin black. Made up a SS oil catch tank using -10AN fittings. Has some baffling and SS wool internally to try and catch as much oil and moisture mist as possible. It will be vented under the front drivers side guard. Found a cheap window washer tank that was the perfect size so made up a small bracket to attach it. Disclaimer: I am a shit welder so no need to remind me. Test fit washer bottle. Test fit in the car. Grabbed a bunch more -10 AN fittings and hose. Painted tank satin black. I removed the OEM push fit breather connectors going into the cam covers and installed a set of Franklin Engineering AN fitting adapters. These come with a tool to allow you to hammer them in nice and straight with out damaging the black finish which is cool. Made up the breather hoses and reinstalled everything. Used some AN divider clamps to try and keep the lines tidy. I still have to make up the vent line that goes to the external filter.

    After sourcing most of the bits I needed it was time to start pulling the thing apart. Platinum Crank Trigger kit fitted up. This requires a small notch to be made in the oil pump housing so the senor fits correctly. Test fit clearance of crank gear to sensor Sourced a set Tomei adjustable gears They went on with new cam belt and w/pump etc. Franklin Engineering CAS Trigger kit installed Pulled out the old twin setup. Sinco exhaust manifold installed, replaced all the exhaust studs with new nissan OEM at the same time. Turbo test fit to get clocking roughly in the right spot. One downside to the BW SX-E stuff is they are big, the front housings are massive in comparison to the EFR range. Intercooler and air filter piping mocked up. Then me and my good buddy X Ray knocked up dump and wastegate pipe. Dump is 4" merging back to 3.5" Wastgate is 2.5". We sure as hell are not winning any welding awards but it should hold together. We tried to keep everything tucked as high as possible for clearance. X Ray had a random old power steering tank off some nissan which I modded to fit around turbo stuff. Ended up fitting in pretty neatly. Exhaust and wastegate fitted up. Oil feed and drain completed. Made up a SS heat shield to try and keep heat away from wiring etc. Dump pipe will be heat wrapped also.

    You sure about that? Most I have seen end 15mm or so before the edge of the bonnet...

    Originally I was going stay with the twin setup and upgrade them but everyone seems to be going the single turbo route these days so decided to jump on that bandwagon. The plan is start with keeping the engine internals stock and just doing the basic external bits needed to make a nice semi quick street car. I wanted to ditch the old school power fc and went with a Link as I think they are pretty good value for money. The car will have some basic engine protection added around fuel pressure and oil pressure sensors along with AFR input via an innovate MTX-L wideband. Turbo wise I would love to have gone for a BW EFR 8374 as the results guys are getting on these turbos on stock 26s looks great. However dude to budget limitations I have decided to try the EFRs poor little brother, the BW SX-E 8376 with a .92A/R TS rear housing. These are a journal based turbo that incorporate some of the EFRs newer tech like the billet compressor wheel. Supra and LS guys in the states seem to like the BW SX-E stuff so thought I would give one a try. Started to order a few parts to get started.

    Painted up engine covers as they were looking pretty shit.
