My coldbox I made the cold box out of carbon sheet with gold reflective finish engine side . It is fed through the vent in the nismo front through fibreglass ducting. It was pretty simple to make but took quite a while to get the top contours of the box exactly right so it seals to the bonnett "carpet" as the bonnett closes using stagea door seals. I have not noticed any sudden power increase but the area is definately cooler than the engine bay so it must be doing something worthwhile.

It is running twin 2860-5s probably the favorite set up in the uk for an rb26 its set at 1.3 bar on low and 1.56 on high with 99 fuel which is about the norm over here ; there is quite a few running a higher boost than me.

Of course it depends on what your low boost is Mine is 19 psi

Another profec B vote It may not be the easiest to set up but if done properly you only have to do it once. IMHO you dont need 4 or 5 boost control settings on a road car - for me 2 is enough Mine has coped with 1.5 bar for over 2 years without any issues ( OK i dont drive it every day) Apart from the fact that a profec b is a good unit may I syuggest a couple of other reasons for using one You can get a remote wireless switch to swop the boost settings. Fits on the steering wheel so you dont have to drive on high boost all the time just in case you want to use it . Get the urge press the button its on high boost instantly - My favourite gadget by far Oh and it happens to fits exactly in the switches hole to the left of the steering wheel

Not sure what you mean ? It is factory just trimmed to match the rest of the retrimmed interior - one bright silver bit looked shocking with everything else black .

10 out of 10 for observation It is actually a profec b boost controller which fits exactly into the hole for the switches. I moved them to the other side as there is an extra space for switches. It is nice and out the way there and I dont need access to it to swop boost as the profec b has the option of a remote switch that can be fitted to the steering wheel (yellow button) I can change from hi to low boost without taking hands off the steering wheel . Best gadget on the car by far imho The guages are electronic apexi ll with white dials . Oil temp & pressure, water temp . fuel pressure , EGT and boost . The guages have an adjustable warning feature which flashes and beep and a peak hold option. You can also set them for 30 second playback . Tried it once after a run up santapod strip - it looks really weird no engine and all the guages jumping around .

So.......... Is there any reasom why I cant just fit GTR hubs and use the rs four s fork nismo s tune suspension ?

Just made up a cool air box as the rb26 runs a bit hot and under the bonnett is pretty high temperatures It is fed through the vent on the nismo front - I made a sealed ducting in glass fibre and enlarged the size of the hole up to the filter area. Fabricated a barrier out of carbon sheet so that the pipes and filters go through and are sealed with heat reflective gold on the engine side I have never liked the sealed top so spent a fair amount of time cutting the top to the profile of the bonnett and then used a door seal which slips nicely over the cardon and seals to the bonnett "carpet" BTW the washer bottle was replaced by a tank that also is an alloy catchtank. That is now where the battery was which has relocated to inside the rear wing - fits a treat

If there is an easier way please explain . Dont worry about the parts Ive already got. I also want to keep the wheels as have just had them redone with new toyos. Plus i think they suit the car

I Need help : I have looked through the topics and cant find an answer specific to my needs and the info simply isnt available in the UK. I have a series one with a rb26 conversion through a late 33GTR box with dual syncros. It is running just over 500bhp at the hubs. Pretty much everything has been uprated to past gtr spec except the rear suspension which is still standard apart from bilsteins so I want to uprate the back end in one go . I also have an RS Four S with stagea specific Nismo S tune supension .This is way better than my current Bilstein set up even though it is only 1500 miles old . Problem is that these have a fork fitting on the rears like all Ss and Rs 260s . I have previously tried swopping the diffs and hubs when attempting to use an RS four S LSD but they dont swop over so easily. So rather than mess about the plan is to rebuild a back end using an RS four S subframe (already sourced)with the Nismo suspension (because I already have it) to the series one and use a HICAS locking bar I already have a set of autech suspension top go back on the S While I am building the new back end I can fit adjustable arms and poly bushes and change the lot in one go. I can then use my current diff which has had a GTR LSD fitted and keep the original Stagea ratios. I dont want to do a complete GTR swop if it means having to change the front diff. Unless of course any one has a better solution ?

Yes they have definately been discontinued They were available for a while under a different part number but sadly both are now finished. I have an account with bilstein and bought the last three sets for stageas in the uk. I have also been told there are no plans to reintroduce them at a later date.

Some pics A few more close up

Sorry Ive no idea of the part number - I dont think it is on the black plastic "holder bag" but will have a closer look This is currenty sealed in a clear old celluphane bag with what looks like 20 year old tape so I am leaving it as it is . AFAIK the stnadard 32 toolkit really is nothing special - screwdriver, pliers plug box spanner plug and rod. I think the jack and wheel nut brace are seperate from the toolkit.

sorry double posted

Its been six months since the last post and things can finally get moving again. Unfortunately its taken 2nd place behind the stagea during the summer plus I simply didnt have a big enough garage to get all the way round the car with it on stands with the garage doors shut. Problem solved . Mother has donated the rear of her garden. Power is going in this weekend then the work can resume. The GTRs home untill it is completely finished . It is sharing space with a future project Ive owned for over 20 years which will be along the same lines if I ever stop spending money on Nissans I now have all the bits :clap: including working clock ,unopened tool kit and original radio , exhaust and suspension (new) The engine bay is finished So just need to fit the exhaust , suspension , discs and calipers , wheels , seats and refit all the carpets etc in the boot and car . Should all be done by Sunday ( but I wont say which one )

No but has a fair few tomei parts Block is early N1 and bored out to max Bearings acl bolts arp but the following are Tomei pistons, rods cams lifters adj pulleys c/belt oil pump h/gasket, probably missed a few bits. turbos 2860-5s hks v pro gold ecu runs just over 500bhp at the hubs (whatever that is in KW)

My Stagea is featured in Japanese performance magazine this month. The guy that wrote the article did seem to quite like the car - although he did seem to lose the plot a bit during a full lauch (I did tell him to put on the harness earlier ) Maybe he still was a bit mixed later up cos he seems to have got a fair bit of the spec wrong as well as some other details . Still never mind a features a feature. Anyway I am now able to post some of the photoshoot pictures as I am allowed to use them once the magazine is out. The static shots were taken at abbey who were kind enough to lend us the back car park (thanks tony ) Ive got a complete CD of pics but will only bore you guys with these The obligatory engine pic Th drive home

It has standard Series 1 RS Four diffs. Re the standing 1/4. Well I said I would post the time so even though it was not what I hoped ...........However this was entirely due to my rubbish driving It was my first ever attempt on a strip which was pretty obvious Time was 13.09 with a crap start (0-60 ft was 2.5 sec ) And then to make things worse I missed forth gear completely At 1000ft speed was 106 I missed gear and and went over the line in neutral at 104 mph so no doubt that the car is very much quicker than me !

Thanks guys I have just bought the S as a runabout as the current Stagea is no longer a "town car" and I need an estate A vicous lsd would be an improvement for sure and as its pretty easy to swop and I have both cars I was simply going to swop the rerar diffs over (as long as compatible) Looks like the diffs are different after all so changing both difffs on both cars is a no no , I will just have to carry on lokin for an lsd for the series 1. Trouble is finding one in the uk is almost impossible .

Not yet but I am going to santa pod next weekend so if anything is going to go it will probably go then. Main question was whether the RS Four S had GTR diffs as I know it has HICAS . If not then the difffs are probably the same ratio which is good news.

I have a series 1 with a forged RB26 engine and manual box. Have decided I need an LSD, Question is what will fit ? Ideally I would like to keep the front as is because changing it is more work than the rear. Ive found an RS FOUR S and can have both diffs if neccessary Anyone know if the ratios are the same as series 1 cars or indeed if the diffs will even fit . Thanks in advance for any help.

my gauges

Thanks for your concern and if the grooves were curved you would be right but with straight cut grooves on APs its the other way ( no I dont know why either) There are lots of different AP disc designs : with these particular discs it is the direction of the vanes that determines the way they go round not the slots. From the AP website (and off of the AP box )

Pretty much all rear calipers have the same hole spacing. I have 34GTR Gold brembos on the rear of my Stagea As you can see they do fit but you will need the larger 34GTR discs Now the bigger caliper bolt holes do line up and they use the same size bolt as stageas the thread pitch is different - you need to use 34 GTR caliper bolts . If you are trying to use the original stagea bolts they can give the impression of not fitting Also because the 34GTR rear discs are much bigger you will need to either swop the dust cover for a 34GTR (or 33) one or cut the dust cover lip off. This can easily be done without removing the covers. This is much easier as nothing else needs to be removed ( hand brake assembly etc) This is certainly true for series one cars If yours is a series 2 I cant say for sure as mine is an S1
