Thought as much - there's the problem. Not the same box and i have NO Kea's components within.

.

Hope you mean something other than the 403 then cos they're basically the same thing and have interchangeable parts (obviously not all parts).

no they are not...01 is very much the baby brother of the 03. Steve explained it all to me why the 01 wouldn't work.

yeah 01, i do know that the 03 is bigger but everywhere they are bigger we have pretty much upgraded on the o1 to o3 stuff, the input shaft we are running now is actually bigger than the o3 and it still doesnt like it. we didnt have any o3's available to us at the time, maybe we should have waited, your car will tell us that! Thanks for the info though Dave, I assume yours is a BMS then??? I think the biggest problem with the car I am running is weight, its around 1600kg's and moving it just kill the gearbox.

Steve does good work have use his stuff before and good service also, KEAS is just a good friend of ours thus why we use him. I have checked your PM, can do mate just send some more details. I will get back to later this afternoon.

Cheers

just need the same baffle arrangment you made me last time - box'd out extention sump.

Maybe I wasn't clear enough. Suggest you speak to Steve again and find out what will go where. I wasn't suggesting any of the hard, mechanical parts are the same. :huh:

Sure you were'nt- As i often qoute . "one should'nt pretend to know if one really does not". :)

Hopefully we dont run into to much trouble using the RE4R03a box but we do realise that we may have to replace one or more of the shafts with vasco items. Its no point replacing all the shafts with $600 a pop vasco items if the stock shafts (re-heat treated) do the job. In most cases ive seen stock shafts that have been softened, rehardened and cryoed have stood up better than 4340 items as in most cases these dont get hardened or get incorrectly hardened. Another thing that will effect the shafts besides engine torque and the weight of the car is the way in which the valve body and transbrake is designed and operates and the line pressure used. Ive seen one particular 4n71b box with so called hituff shafts crap themselves whilst the same type of box with re-hardened shafts last for years in another vl that had a lot more hp and also ran slicks.

I have had a few RE4R01a built by bms using re-hardened shafts (skyline input,subaru tall 1st, and mazda output) and havent had any breakage problems but these are used in fairly light cars like a Datsun 200b that weighs around 1000kg and runs 10.7 with a 1.4 60ft which has done around 100 passes. Before rigoli went rwd in his subaru they also used the RE4R01a box with a glide sized output shaft (the subaru version uses a smaller output shaft) that ran like 8.3 at 160 odd.

Steve has said that any shaft problems and he will jump straight on a plane and go get 10 vasco shafts made (10 is min order). We believe these RE4R03a boxes have great potential to be used as either a drag box in transbrake form or as a street box in reverse braking form. Setup with a good converter these boxes are great in a streeter as they can reduce lag and make the most of the huge midrange torque that turbocharged cars have to offer. We all now how weak a stocky gtr box is and what it can cost to replace these with something stronger. I think more guys need to go for a drive in a well setup auto in a turbocharged car.

Thanks for the input Smiley, given your back ground people should listen and learn from what you have to say as there is no compromise for experience.

Guys - if any one wants a performance engine built to a above average spec then touch base with Smiley fron DATSQIK HARDCORE JAP ENGINES, for he has been playing with Turbo charged engines before half of you were even born. Please don't bother him with basic questions , simply touch base if you want the best build and he will advise as to whether it's interesting enough for him - Yep - one of those guys, knows his shit rather than talk it!

The box should hold up ok...its the convertor im worried about. Ive got a RE4R03A 4WD box with factory Nissan transfer case out of an A32 Cima on its way from Japan. Ill pay Steve to set it up if you guys can hold convertors up to it. My car is 1360KG without driver and is capable of over 950AWHP...Dom Rigoli seems to think that ill split convertors and it will not work due to the weight...their car is much lighter than mine and they have huge convertor trouble. PPG dogbox will stay in for now.

Best of luck with it guys.

Hopefully we dont have any converter problems. I have seen similar deisigned converters holding more power. We are using a 9 1/2" outside with 8 1/2" inside and have been able to squeeze a mechanical diode in there. From what limited time we have had the converter in it feels fairly tight and is designed to hold 1200hp at 6000rpm. Only time will tell from here on in.

A little more to "eye ball" - Kept blowing the exhaust duct off. Your probably seeing about 800hp here, will post some larger numbers later - Thanks Timbo and Smiley for the video work.

    • The average previous owner for these cars were basically S-chassis owners in the US. Teenagers or teenager-adjacent. I often tell people that neglect is easier to fix than something that was actively "repaired" by previous owners.
    • Update 3: Hi all It's been a while. Quite a lot of things happened in the meantime, among other things the car is (almost) back together and ready to be started again. Things that I fixed or changed: Full turbo removal, fitting back the OEM turbo oil hardlines. Had to do quite a bit of research and parts shopping to get every last piece that I need and make it work with the GT2860 turbos, but it does work and is not hard to do. Proves that the previous owner(s) just did not want to. While I was there I set the preload for the wastegates to 0,9bar to hopefully make it easier for the tuner to hit the 370hp I need for the legal inspections that will follow later on. Boost can always go up if necessary. Fitted a AN10 line from the catch can to the intake hose to make the catchcan and hopefully the cam covers a slight vacuum to have less restrictive oil returns from the head and not have mud build up as harshly in the lines and catch can. Removed the entire front interior just shy of the dashboard itself to clean up some of the absolutely horrendous wiring, (hopefully) fix the bumpy tacho and put in LED bulbs while I was there. Also put in bulbs where there was none before, like the airbag one. I also used that chance to remove the LED rpm gauge on the steering column, which was also wired in absolute horror show fashion. Moved the 4in1 Prosport gauge from sitting in front of the OEM oil pressure gauge to the center console vents, I used a 3D printed vent piece to hold that gauge there. The HKB steering wheel boss was likely on incorrectly as I sometimes noticed the indicator reset being uneven for left vs. right. In the meantime also installed an airbag delete resistor, as one should. Installed Cube Speed premium short shifter. Feels pretty nice, hope it'll work great too when I actually get to drive. Also put on a fancy Dragon Ball shift knob, cause why not. My buddy was kind enough to weld the rust hole in the back, it was basically rusted through in the lowermost corner of the passenger side trunk area where the wheel arch, trunk panel and rear quarter all meet. Obviously there is still a lot of crustiness in various areas but as long as it's not rusted out I'll just treat and isolate the corrosion and pretend it's not there. Also had to put down a new ground wire for the rear subframe as the original one was BARELY there. Probably a bit controversial depending on who you ask about this... but I ended up just covering the crack in the side of the engine block, the one above the oil feed, with JB Weld. I used a generous amount and roughed up the whole area with a Dremel before, so I hope this will hold the coolant where it should be for the foreseeable future. Did a cam cover gasket job as the half moons were a bit leaky, and there too one could see the people who worked on this car before me were absolute tools. The same half moons were probably used like 3 times without even cleaning the old RTV off. Dremeled out the inside of the flange where the turbine housing mates onto the exhaust manifolds so the diameter matches, as the OEM exhaust manifolds are even narrower than the turbine housings as we all know. Even if this doesn't do much, I had them out anyways, so can't harm. Ideally one would port-match both the turbo and the manifold to the gasket size but I really didn't feel up to disassembling the turbine housings. Wrapped turbo outlet dumps in heat wrap band. Will do the frontpipe again as well as now the oil leak which promted me to tear apart half the engine in the first place is hopefully fixed. Fitted an ATI super damper to get rid of the worn old harmonic balancer. Surely one of the easiest and most worth to do mods. But torquing that ARP bolt to spec was a bitch without being able to lock the flywheel. Did some minor adjustments in the ECU tables to change some things I didn't like, like the launch control that was ALWAYS active. Treated rusty spots and surface corrosion on places I could get to and on many spots under the car, not pretty or ideal but good enough for now. Removed the N1 rear spats and the carbon surrounding for the tailpipe to put them back on with new adhesive as the old one was lifting in many spots, not pretty. Took out the passenger rear lamp housing... what do you know. Amateur work screwed me again here as they were glued in hard and removing it took a lot of force, so I broke one of the housing bolts off. And when removing the adhesive from the chassis the paint came right off too. Thankfully all the damaged area won't be visible later, but whoever did the very limited bodywork on this car needs to have their limbs chopped off piece by piece.   Quite a list if I do say so myself, but a lot of time was spent just discovering new shit that is wrong with the car and finding a solution or parts to fix it. My last problem that I now have the headache of dealing with is that the exhaust studs on the turbo outlets are M10x1.25 threaded, but the previous owner already put on regular M10 nuts so the threads are... weird. I only found this out the hard way. So now I will just try if I can in any way fit the front pipe regardless, if not I'll have to redo the studs with the turbos installed. Lesson learned for the future: Redo ALL studs you put your hands on, especially if they are old and the previous owners were inept maniacs. Thanks for reading if you did, will update when the engine runs again. Hope nothing breaks or leaks and I can do a test drive.
    • No those pads are DBA too  but they have colors too. I look at the and imo the green "street" are the best.
    • I’m not sure what happened I told them about sonic tunes free OTS tune and the next the I know .. I was booted..   To funny
