  1. Bigger Air Filter = Better?

    Interestingly NA's actually requite larger filters than force fed motors. I had a table listing what minimum size your filter needed to be for a given hp for both NA and turbo engines, I will post it if I can find it. If you can fit a filter with a v stack it makes a big difference.
  2. 78 RB26 260Z

    Thanks. Not as sick as I felt I'm sure. I was meant to be heading to the Biggest Jap car show in the UK the next day and I'd got a space on the Top 20 arena, so gutted I didn't make it, had the ferry and B&B's booked and a friend arranged to come other with me, properly gutting. Thanks, its nice to have your own place, and I'm super happy to now have somewhere my own to work on the cars inside, no more lying on wet ground in the rain for me.
  3. I'm still planning on sticking an RB26 in this so thought a build thread would be a good idea. The first few posts are just copied: Just bought my first Datsun and I'm really happy with it so thought I'd post some photos. I've still got loads to learn about these cars so I'm sure this forum will be a huge help. 1979 Datsun 260Z Shes in great condition, only 28480 miles on her when I bought it although its not far of 29k now. She was built in 1978 but only first registered in 1979 and going by the chassis number she was one of the the last to be imported from Japan to the UK. Theres few photos with my Civic in them also, shes a 1991 Civic running a 243hp B20. It drives beautifully, its had new bushes all round and with the low miles on the chassis it still feels really tight so its a joy to drive. I have real big plans for her involving seam welding, cageing, hugely uprated suspension and brakes and an engine swap, I like the idea of a V10 because I love them but failing that I'd like an RB26DETT. For now though the first mods will be: Paint the brake calipers and drums Polish up the lips on the wheels Give the engine bay a good clean Clean out the carbs Do something with the rocker cover Give her a full detail, I've already done the inside but the outside still needs done After that lot I'll be fitting a bigger better airdam and a rear spoiler follwed by a good coilover setup with adjustable camber plates welded in as shes definitly too high at the moment. Then I'll have to fit the arch flares before I can fit my new wheels other wise they won't fit. Photos Sorry for the amount but I couldn't decide which to put up.
  4. 78 RB26 260Z

    Then this happened. Someone old lady pulled out in front of me in a 60mph limit, I had no chance of stopping in time. Then she claimed it was my fault later on, I didn't want to loose my no claims and wanted the car repaired properly so I took her to court and Won of course, but it took over a year since the accident. Its not that bad but still is about £10,000 of damage, the airdam, bumper, bonnet, headlight bucket, headlight case, headlight, headlight cover, wing, indicator front, indicator side, grill, diffuser plate and two wheels where they touched the kerb are all damaged, as is part of the inner panel meaning the engine will have to be removed to straighten and repair. So, the car hasn't been on the road in over a year, between breaking my fibula and tibia wakeboarding to getting my first house and my Job commitments I just haven't had time. In good news however I bought my first house, and it has the all important triple garage, so I now have somewhere to store and work on my cars. That was the main reason for going with this house tbh, petrol head prioritys. The garage isn't much inside at the moment, but I have big plans for it, once the Datsun is sorted again it will be my next project before I can start another car project. Plan to extend the two right side bays longer to allow room for cabinets and benches with room to work on a car all round while it is on a scissor lift which will be recessed into the floor. Walls will be painted, floor will be tiled, insulation added to the roof, the two left bays will get a loft for storage and I'll fit flat led lighting panels recessed into the ceiling throughout. Got most of the parts needed to fix the Datsun now, I decided I would try and cut some weight So I got Marugen Shoukai FRP wings, amazing quality and only weigh 2.15kg each. I wanted a carbon fibre Bonnet, but nearly all available are actually fibreglass with a cosmetic skin of carbon. I wanted full dry carbon. Only two options I could see were Topstage Composites and Restored.JP. I went for the restored one, it weighs 5.7kg. Inside will stay carbon, topside will be body colour. Skillard full length grill I decided recently that I would go all out, so the whole car is going back to bare metal, only rust is a few spots in the floor plans, this will be repaired along with some more seam welding in the rear, some minor mods in the engine bay and I will be extending the frame rails to join the rear sub-frame. Currently trying to decide if I want to add a half cage or not. Stripping in progress. The sound deadening was a pain to remove, even with dry ice. I plan to re make the interior wiring while building her up again. Work should be commencing when I am on leave in July. So can't wait to drive her again. My sump needs better baffling and the flange isn't flat so I plan to either start from scratch or cut off the flange and re make the current one with a new flange, wings and an improved trap door setup. This will be done while the engine is out the car for the body work. Got some RB26 flanges ready to go.

  6. 78 RB26 260Z

    Just a few updates since I've not added anything here in a while. My Custom Blueprint, ordered this in A3 size but it was so nice I had to order another in size A2, good news is I can now have one in my hall and one in my Garage. Plan to get one for my Civic also so I can have them on the garage wall behind where the cars live. Changed some rubbers Overflow tank fits perfectly: Received some lovely parts from T3: Unfortunately the hubs won't fit without spacers Fitted them to find they leave the disc sitting about 8mm further out than the stock hubs so I had to remove them again. T3 have now sent me a spacer which should leave the discs sitting correctly. Not sure if I will use them yet though as its seems that almost no wheels will fit them without a spacer, does anybody know if they will fit Watanabes? T3 sent the spacers to me, I had asked for new bearings also because I had to fit the first new set back into my old hubs, I had expected to pay for these but they sent everything for free, I'm always happy with their customer service, top quality parts and great customer service. Working on a carbon fibre splitter Got myself a VBOX, yet to try it out properly but will post results once I have. I decided my washer bottle was letting my bay down, so I decided to have a nicer one made to my specs: It wasn't cheap but its a work of engineering art and respect of the skill levels required to make it: Upgraded my carbon wrapped taillight panels to real ones, didn't want the shiny look so went for satin finish. They look good but the mounting tabs for the lights are really really weak and half broke off so I am thinking I am planning to real carbon skin my stock ones if I can't repair the tabs with some Sikaflex.
  7. V10 240Z build on YouTube

    I hope it fits, this way my first choice for an engine for my S30, but I figured I wouldn't have had the money for the fab work or the time to be able to carry it out so I went for the RB26 instead. I doubt it given that he seems to love the engine he is not going to ruin it by turbocharging it, plus 1000hp in an S30 isn't really useable like a 550hp NA S85 would be.
  8. 240z RB26 Track Spec Build

    Well make sure you get every single last minuscule grain of rust or you will find it reappearing after only a couple of years, then you have to do a lot of hard work all over again. Thats why I like blasting, I get it cleaned and in primer within a day of being blasted maximum.
  9. 240z RB26 Track Spec Build

    Why don't you get it media blasted? Bet way to make sure all the rust is gone.
  10. Refinishing small parts

    I get all small parts sandblasted, then I prime them and paint them with a durable chassis black paint, I prefer this to powder-coating and its easy to do.
  11. So this may be a stupid question, but I am sort of worried about changing things at my rear end too much because I actually have really good traction with how my setup currently is, much better traction than it seems most other people with S30's are getting. A lot of other modified Z's are running upgraded moustache bars and drop mounts but don't seem to have good traction so I am just wondering if it was possible that having some flex in the system could actually improve traction and if changing my stock ones for T3 might not be a good idea. So am I being crazy?
  12. 78 RB26 260Z

    Thanks. Only in America. In the UK we got the 260Z up to 78 (actuallty after 78 but they stopped making them in 78, I think the last were sold in 79 which is when mine was bought), because we didn't have all the power sapping emissions shit on the L26 it made around 160hp so we never needed a 280Z which was not released here.
  13. I was thinking that the slight flex in the system takes some of the shock out and prevents the wheels from breaking free as easily as they would if everything was solid. Hence me thinking my planned upgrades might not be an upgrade. Still considering the T3 drop mounts though as they would allow me to run a finned cover so I don't fry my OS Giken CLSD.
  14. I am considering getting a half cage made for the 260Z. Mainly to stiffen up the shell, provide an attachment point for the odd time I would want a harness and also to add some safety in the event of an accident. Has anyone here got experience running a cage? Do you see a noticeable difference in chassis rigidity? Problems with insurance? I imagine a decent half cage would add at least 30kg which is not so desirable. I am thinking something along the lines of these (only without the front half on those that are full cages)
  15. I'm not sure, might be able work with it: What doesn't help is that I work away from home, so I can't actually physically check things, doing all my planning from my memory and photos.
  16. Thanks for your thoughts. I can say now that whatever cage goes into my car won't be perfect, it will be a compromise because I'm trying to have a car that car is good at many things, its mainly a street car and I want to keep that classic feel to it and don't want to loose interior functionality. It also has to be capable on a circuit and on a drag strip. 1 - X up high - good point, I can do without an x and just use 1 diagonal bar to save weight. 2 - I would like to do the backstays to the top of the tower, but doing so would mean loosing my seatbelts and I sure as heck don't want to be running harness anywhere other than on track. If you have any idea as to how I can re-engineer my seatbelts to somewhere else them let me know. 3 - Will do without these bars 4 - Again, I want to keep the interior nice looking and as original as possible so I don't really want to have bars running there. 5 - Not sure what you mean, the bar is straight across the towers, albeit slightly forward of where would be ideal, if this is what you mean I could always have it right across the middle and have this bar separate from the rest of the cage. I will be connecting with a plate to map light area. This is about as good a cage I get while keeping the seatbelts and keeping weight down, will it still have enough of an impact on stiffness to be worthwhile?

    Nice photos, shes a great looking car. Looks like you took those photos in bright sunlight, its always hard to get good shots in midday sun, best time is late afternoon and sometimes in the morning.
  18. Z Car weights

    Thats a good weight for that setup, gives me hope.
  19. I am with a specialist insurance company due to the mods. I actually had to renew it the other day (nearly £800 ) so I took the opportunity to check if it would be an issue, for them it was't and wouldn't cost any more since my car is already super heavily modified. I don't see it like that, you are connecting the two suspension towers, connecting the towers to the rocker panels which provide a lot of the strength for the car and also providing a fairy rigid bar connecting the two rockers together and then theres a bar coming off the top of the towers whihc must help somewhat to provide some vertical stiffness for the towers upward against upwards forces. I would consider connecting it to the roof as I can use some plate in the middle and still run the trim as I would just need to trim a section out the plastic to allow it to fit. My front is as reinforced as I can make a road car so I'm no longer worried there. Honestly my front end feels solid and no creaking or any visible flex no matter where I jack it up. Heres the cage I have in mind (just imagine all the lines are where they should be as I couldn't get it perfect in paint) I plan to have the main hoop uprights part recessed into the well. With this design I reckon I can still run my stock belts. The bars in yellow are optional if they are thought to be needed. I do realise that without a diagonal in the main hoop I am loosing strength but I don't want to sacrifice the room and its not like I am racing in any competitions plus I'm sure even without I'm still going to be much safer than with no cage. Correct in both cases. But I think the cage above will be solid and still let me run my stock belts. Of course I am not a cage designer so it could be deeply flawed. I guess modern belts mounted to a small floor reel with the upper mount mounted to the cage would work. Other ideas for fun, tell me what you think. With no cage what is better, x on its own, bar on its own or both like below or is both not adding much other than weight?
  20. My seatbelts mount on the top so I'd rather have them just in front of the top on the vertical. Just looked it up, thanks, got some ideas from that. Totally wouldn't want a full cage with door bars, but with the design I have in mind for my half cage I can't see it getting in the way at all. My frame rails are good and I will be extending them to the rear subframe so its good to hear this proves worthwhile. Thanks. I actually read that thread before I even bought my Z. I have or will have 1, 2, 4, 7, 8, 11, 12, 13 and possibly 3 as we are discussing here. With my design that I have in mind I do not believe I will loose any seat travel, at least not any of the adjustment I would need for driving. I may make a removable harness bar as I would only be using harness on track, drag strip or runway.
  21. boosted300's RB 240Z

    Such a great looking Z. Hard luck on the AC, I hope you get it sorted soon without too much more hassle. I'm lucky that I do'n't require AC where I live so I don't have that headache, although sometimes I do wish the weather was warm enough often enough that i did require it.
  22. 78 RB26 260Z

    Not sure on exact brand, but they both came from MSA and I am happy with both of them if you are thinking about them. Thank-you very much fellow RB-Z brother. Hope to get this thread updated this week.
  23. Z Car weights

    I have full interior, radio with 2 small speakers, 10kg's of sound deadening, lightweight carpet throughout and thats it for the comforts. But I do have 225/50/16's all round and will soon run 245/45/16's on the rear. I have big brakes all round, but the front setup weighs no more than the stock did and the rear didn't add much either over stock. Other than that its only what the RB added over the L26. Plus beetween removing unused parts, lightweight battery, coil-overs being lighter and some light weight body parts I've removed over 50kg from what it was stock. I would now be happy with anything under 1200kg with a small half cage. With 490HP and 490LBFT it still makes for a decent power to weight. I dream of upgrading to a titanium exhaust system at some point down the line.
  24. Z Car weights

    Interesting thread, These S30's are a lot heavier than I thought an hoped for. I was hoping for 1100'kgs for my RB-Z. Thats with Carbon bonnet, FRP wings, lighter coilovers, alloy hubs and thats about it for the weight saving. Its looking like I'd be lucky to hit 1200 once my half cage goes in (estimating 25-30kg) Bit disappointing. Next car project needs to be lighter. Will weigh mine once current work is complete.
