Would love to compare it to my rb25 6062 setup in terms of response. QLD or Syd roll racing? Also curious on what headstuds youre using?

Also very curious to know what the spool is like! Looks like it would be an absolute weapon, good job!

Yep same as the ebay kit. Have a look back through this thread, pretty sure a few people have had a wait on the ard alternators and not readily available and cheap like ls1 alternators. Pick up 2nd hand ls1 alt for $50-$100. As you said the advantage is being able to remove the pulley & adapter to use it on another ls1 alt if need be but if you buy a new one in the kit the likely hood of needing to replace should be pretty low. I'd send Andrew a message and get a price. His number is on the thread a few pages back.

Received & fitted my kit from Andrew yesterday. Andrew was very easy to deal with and sent the alternator off asap. Overall very happy with the kit. It was packaged very well for postage. Quality looks great and everything was there for a quick install. Have around 14.2v @idle when warm. I would highly recommend the kit to anyone considering it. Cheers mate @rat32r

Yeah I'm curious as to what oil this might be.? The guy who built the box said to run some penrite 80w90 with some nulon smooth shift but im interested to hear any other experiences.

Bought a gearbox with a speedtek gearset yep. Haven't put it in the car yet.

Updates? What grade oil would be best suited?

Hey all, Bit of an update from late last year. Precision 6062, built s1 rb25det, e85 etc Got it tuned last year and it made 431kw @26psi apparently the turbo was maxed out. Dyno dynamics roller dyno. I decided to change the wastegate springs from 14psi to 21psi, fixed a boost leak i found underneath the intake manifold ( idle control- cold start valve area ), hpi evolve radiator and decided to run a viscious fan again. Might have been a few other minor changes. We stopped at 29psi as we were a little worried about the arp 2000 headstuds not handling much more. Turbo seemed to be still going and I think we could have gotten a bit more out of it if the headstuds weren't a limiting factor. This is on a mainline hub dyno so it is 710hp at the hubs. Still quite happy with the result and I'm sure the 6062 could keep pumping. I attached a video of the run, hopefully it works. We used Real Dyno hub dyno and Brad Sheriff from Boost Automotive Tasmania tuned the car. 20190515_160226.mp4

Yeah going to upgrade to 21psi springs in twin 45s. Ill also change the gate pressure source from the turbo to the intake manifold before I put it back on the dyno. Found the pipe in the white circle that comes off the idle control block that wasnt blocked off either. Blocking pipe must have blown off so it would be leaking boost out of it. Fixed it up now so once ive put the springs in and finalized a few other bits and pieces I'll gey it back on the dyno.

Pulled the duty cycle up today. What do you guys reckon?

Still retains vct yes. I'm just going off what I was told, I'm not a mechanic and only have a pretty basic knowledge. I'm interested to hear what you all have to say and if there are a few things I can check. I've seen your build Simon so I did find it weird for the compressor to have run out. Obviously different builds here but still for it to be that different. I was hoping to screw a bit more into it. I'm not entirely sure on the pre-intercooler temps sorry, just what I was told. I didn't before you mentioned it, just had a look. Unsure how mine is set. Twin 45mm hypergates with 14psi springs. Pretty sure they are 7psi inner and 7psi outter?

Hi all, Back again and had the car on the dyno on Monday with the only change being the 600x300x100 cooling pro intercooler. Compressor seemed to run out of puff at 26psi and tapered off to 25psi by the end of the run which was a bit disappointing. Saw a bit of wheel spin on this run as you can see at the top. For a $260 intercooler it made a pretty good difference. Car is pretty incredible to drive, it has awesome low end torque and it quite responsive. Keen to test it out at roll racing in a couple of weeks. -Ryan

+1 for Brad @ Boost Automotive Launceston. When I was living in Tasmania, I used him to tune my car a few times. He is great at what he does and is very knowledgeable.

Turbosmart oil pressure regulator Ecu: Haltech platinum pro Had to stop at 25psi, ebay intercooler wasnt keeping up at all. Was jumping from 45 to 65degrees during a run. Purchased a cooling pro 600x300x100 cooler as recommended by my tuner (Matt Ashley @ Diversion Garage Brisbane. (Would highly recommend)). See how we go once the new cooler is on but im hoping we will be able to wind it up a bit more. See where we end up. So far I can say it seems to be an awesome street setup. A lot more respsonsive compared to my old gtx30 setup. I'll keep you guys updated, should be back on the dyno in the next fortnight. Cheers, Ryan.

Has anyone ran a 6062 on a rb25 yet and got some solid numbers? Going to change my current single scroll gen 1 gtx30 to a twin scroll 6062 twin 45mms, maybe depending on results. Wanting to crack the high 400kw maybe even early 500s while keeping respectable response for the street, sees a few track days. Roll racing, power cruise etc.

Gday all 1993 r33 gtst rb25det Tomei poncams 256s 8.5mm lift supertech valve springs w/ matching retainers forged short block with cp pistons and tomei rods. Acl race bearings. Arp bolts all round.

This is just the base tune which made 295rwkw at 17.4psi, caltex 98. Coilpacks were holding it back on running more boost as they are on their way out, so i am converting to ls1 coils before tuning to e85. Full fuel flex system in the car ready to go. Will update when the e85 tune happens. Cheers

Pistons, rods, bearings sold. Only have the crank left. $450 ono Cheers.

Hi mate, Are you still after pistons and rods?

Sard 700cc top feed injectors x 6 Near new injectors, have done under 1000km Came out of a running r32 GTR rb26dett Flowed at 72% to make 321kw at the rear wheels New o rings on top. Was planning to use them in my rb25 but have larger injectors so I have no need for them anymore. Can have them cleaned and flow tested at the buyers cost. $400 Negotiable Looking for a quick sale if possible Located in Tasmania. Willing to ship at buyers expense. Feel free to contact Ryan on 0438368891

Hi all, first post for quite sometime. I have for sale a forged piston and rod kit with a reconditioned rb25det crank. Forged CP 86.5mm (20 thou over) 9:1 compression ratio pistons and rings. CP piston part number: SC7305 Con rods are Bridgeway rods. Great quality rods and quite pricey too I might add! Bridgeway Part number: 6-BR-019-02 Forged billet 4340, H Beam Pistons, con rods and rod bolts are together and balanced. Also have ACL race series bearings. Performance Rod bearings Designed for high rpm Part number: 6B2960H-STD Main bearings Part number: 7M2428H-STD I also have a reconditioned rb25det crank. Balanced, polished, crack tested, etc, etc. With an N1 crank collar. Reconditioning was performed by Tasmanian Engine Reconditioning (Tas Engine Reco) Still in the wrap from the shop! These are quality parts, brand new never been used. Was planning on forging the rb25det in my R33 but have bought one with a forged engine so I have no need for these anymore. Ball park figure is $1600. I know it seems like a lot but look the parts up yourself and youll see this price is quite reasonable, especially once you consider the reconditioning of the crank with the collar. LOCATION: HOBART, TAS. Willing to ship: Happy to ship interstate at the buyers cost. Not really looking for swaps at the minute as Im funding a new turbo set up on the rb25. Cheers guys, feel free to get back to me with any inquiries. Ill try to answer things to the best of my ability. Contact name:Ryan Mobile:0438368891 Email: [email protected] More photos upon request if you really feel the need, ive just taken the essentials to show you the parts.

Cheers for the help everyone. Thanks mat for the info on when the 044 maxes out. Did anyone know what type of flange the stock exhauat manifold is? Like where the turbo bolts on? Ive found a turbo but i dont know whether it will bolt straight on or not. A gt3076r. T4 four bolt apparently.

Cheers for all of the replies guys. Had a bit of a look through the dyno thread. I reckon I will be running bp ultimate or shell vortex for the dyno, but I usually run 98 anyway. I had a thought about running a gt3076r or hks 3037. Both pretty much the same i'm sure, both turbos are good for around or a tad over 500HP which isn't too bad at all. I'll most likely go with what most of you said and not limit myself too much on the injectors so I might go larger, something like the 740cc injectors. Just so I'm not maxing out the 550's. Also I reckon I will be going an 044 external with a surge tank rather than maixing out the 040 intank. From what I could find, 040's are good for 250-270kw which is what I'm after, but a 044 might benefit me in the long run if I decide to keep going up. Cheers Jim for reassurance of buying second hand, it was an idea in the back of my mind but I just wasn't 100% sure on whether I really should or not. I've found a gt3076r for $1000 so I might possibly look into that.

Yeah hi flowing thw standard turbo did cross my mind bit why pay $1500 to make the standard tuebo better. I mean yeah i think on average 240-250kw is found at around 18-20psi with the hi flow but i could get something else for that price or a little more and possibly see over 260rwkw. I was thinking something like a gt3037 or something like that. Theyre the same price as the hi flow and could possibly yield better results in the end. The reason i was only going 555cc injectors is because I am using the car as a daily so im after not great fuel efficiency but a reasonable fuel efficiency. Just trying to find the happy medium pretty much. Good horsepower without the really really crap fuel efficiency. Cheers Ryan

Hi Guys, I'm new to site, I've had a bit of a look around and can't seem to find the complete answers on most of the posts. I have a 1993 S1 R33 skyline running a pretty much stock rb25det Right, so my idea is that I'm after 250rwkw+, anything on or over that, I'll be pretty happy with. As I said the engine is pretty much stock. Only mods it has are: Splitfire coil packs Heavy duty clutch 3" exhaust I have on the way a front mount intercooler and a triple core aluminium radiator and I also have a Power FC My plan was to help me get to 250rwkw+, I would run a setup similar to this: Power FC Front Mount 600x300x76 Aftermarket radiator Split fire coils HD clutch 3" exhaust Deatschwerks 555cc injectors Bosch 040 fuel pump Standard Motor Standard Cams Standard intake and exhaust manifold and of course a bigger turbo I'm trying to be on the tightest budget possible at the moment without doing anything completely dodgy and cutting too many drastic corners. To any who have or are planning to go down a similar path, what do you think this set up will be like and what other things can I do to make it a more successful setup? Also with the turbo, I'm after opinions from people on their experiences with different turbo's. I'm after something that isn't going to lag heaps but will spool up around 3-3.5 and pull right through to 7. Something with some good torque that will throw you back in your seat but will keep pulling hard until limiter. Pretty much I'm after the right turbo to complete to combination and get the best results. After the best bang for my buck. The right combination is obviously going to give me the best result so any help would be greatly appreciated. Sorry for so many questions in one post just after the right info. Thanks everyone in advance, Ryan
