no mandrel bending is a form of bending where you use a mandrel...to bend.... hence the term 'mandrel bent'. it's name has nothing to do with the fact that you can bend whilst maintaining pipe diameter. if it did it would be called "same pipe diameter retention bending". the name refers to the method of bending not the outcome. like "press bent" "mandrel bent" "cast" etc.

stock lift is around 8mm. maybe 8.5mm. edit, stock are 240 in with 8.58 lift and 236 ex with 8.28 lift.

sounds to me like faulty 02 sensors. when they go it will cause the car to not run right under light throttle 'cruise' type conditions and gives the symptoms you describe. the good news is any good workshop can easily test them for you with 10 mins work. they just need to hook up a consult/scan tool to your cars diagnostic port and then they can check the sensors (there are 2, one in each dump pipe).

not sure if I'd got that far....

I think the answer is ease of install, cost, and tuning reasons. as I said you can get off the shelf multi-throttle upgrades that will support over 1000hp so it's not purely a power thing. the problem is cars with big singles that are running MAP based ecu's often have trouble getting stable pressure readings from the small vacuum chamber between throttles and head. by moving to a single throttle pre-plenum instead of multi throttles mounted post plenum you now have a much bigger volume of air to work with which dampens down those fluctuations. the other reason is cost. you can buy an off the shelf aftermarket plenum AND a big single throttle for the cost of a nice set of aftermarket multi-throttles and the single throttle is simple to set-up with big single turbo, big cam, MAP based ecu applications. as far as advantages of going from the stock multis to a single FBW. well you will always loose a little throttle response by moving the throttle from post plenum right next to the inlet ports to the pre plenum spot. BUT by being able to tweak the throttle response maps you may get some of it back. the main benefit is being able to tailor the throttle map to suit what you want, but tbh I don't see that much benefit in it. like you said all you should need is the FBW throttle, an adapter plate to attach it to your plenum of choice, the pedal position sender and some wiring. then of course you need to set it up in the ecu. the only other thing to consider is what to do about the stock throttles if you keep the stock plenum? lock them open is not the best solution, and if you remove the rods and butterflys you may have to weld up the side holes. the best option is probably get an aftermarket plenum that will fit up with appropriate length runners without needing the stock throttles there. personally it seems like a lot of cost for not much gain, but if you want to do it, go for it.

well the 32 comes back as a KBNR32RXFSZN model. I can't remember of the top of my head if that's N1 code or not. I think it is. pretty sure the ZN at the end puts it as an N1.

BYO sponge. lol. possibly bad wording on my part but you know the piece I mean. sits in front of the timing belt gear. smarty pants!

like tony said you should 100% NOT drill the 3rd and 4th runner while still fitted to the car. There is no way you can drill and tap those two holes without getting swarf in the engine. I have previously been a big fan of doing it properly and installing the 2 nipples in runners 3 and 4 post throttle body as apexi reccomend. some people do the dodge and use one of the post throttle body vacuum lines coming off the little vacuum box and just tee it into 2 feeds for the 2 map sensors. I had previously seen people have problems with that, but lately 1 or 2 have seemed to still work quite well doing it that way. personally I'd rather do it properly, the downside of course is it's a pretty hefty labour bill to remove and replace throttle bodys etc just to drill and tap 2 holes for the nipples. talk to the bloke tuning it and see what he wants.

that sucks. they may just need spacing out to clear where ever they are hitting, or you may (bigger?) cut outs in the piston skirts to clear them. but cutting into the skirts after finishing is not ideal. it's better if you can adjust the position of the squirters a bit. just depends how much interference there is between the two and the skirt design, skirt length etc. got any pics of the pistons?

exactly. the old guard ensure regs favour the old cars they and their friends own, love and have invested heavily in. look at the size and scope of historics too, and look at the very interesting cut-off dates for the classes that basically exclude nearly everything japanese (as they only really kicked on in a big way from the 80s and with turbo cars in the late 80s-90s). we both know how competitive GTSTs, GTRs, Supras, FD RX7s, MR2 turbos, etc could be in certain classes but the regs are there to exclude them, or if they are allowed the regs un-fairly penalise them. late model 80s-90s japanese turbo cars are about as welcome in australian motor racing as an american soldier in Afghanistan.... and that goes for both grass roots amatuer type events all the way through state and national competitions too. but as I said things are improving little by little.

well regardless of whether or not the o-rings are the source of your problem they 100% need to be replaced so do that first. stick with a set of new genuine ones providing of course they are the right size for your wrx injectors. i would say it should fix your problem, but if it doesn't you'll have to keep hunting. nothing lost though cause those o-rings needed replacing regardless.

I have never heard of anyone bothering. the standard 6 throttle set-up is a good thing. and if you find you need more flow there are at least 3 larger 6 throttle set-ups that I know of (1 over bore, and 2 complete replacement set-ups) and if they are not big enough (the biggest is said to be good for over 1000hp) then there is a wide range of big single throttles up to 100m or so. sure with drive by wire throttle set-up you can write nice throttle curves etc but for the cost and effort involved I don't really think it's worth it. In answer to your question though, I personally have never seen a drive by wire throttle set-up on any GTR either 26, 28 or 26/30 and I have probably seen under the bonnet of thousands of GTRs...

yeah agree the gold is not my cup of tea. nor is the green for that matter (I refuse to call them by their stupid names!). I would take silver, white and black and purple over both those 'special' colours any day. but like you say for someone who likes it, the M spec looks to be a good car, and is a bit 'special' too. for someone after a neat GTR it would be worth looking at that's for sure. I still would have considered the N1 if I thought I could win it really cheap but I don't think it will be. shame it's not nicer.

well I am still available.... have some 09 formula ford experience so I'm practically an open wheeler specialist. just need to get my pro FIA super licence, what do they cost again? 2 cornflake tokens or 3?

what a shame, his tranny gf has split. I always have thought hamilton was a suspect anyway. I suspect he likes button just as much as nicole does.....

yeah you should be able to run older defi link BF or defi link gauges that you used with a type 1 controller with a new type 2 controller. if you want to be sure try and find someone with a type 2 controller and plug in one of your gauges and see if it works. I run the type 2 controller and defi link BF gauges in the GTR but not much good to you I guess being in sydney.

if it's old and you're concerned about it, consider buying a new stock one. they can be bought from nissan for not too much $ and get a new washer, back washer and new bolt too.

yeah I was looking very hard at the 34. it was actually up last week and was passed in. I think the owner is probably after about 3.8mil or so which would put it just under $60K on the road. had someone have a quick look and the interior is pretty worn for a car with only 28K kms and has ciggie burns in the roof lining etc. previous owner didn't really look after it it seems. I was pretty keen but don't think it's one for me. the gold Mspec that's up today does look quite nice though. could be a good buy.

what's the tuned record now? last I looked it was 1:35 and I was at 1:38 but don't think I can do much better with a control pad. should try with a wheel.

looks like poor tune to me as it's making the right boost at the right time. could be a cam timing problem though too. also what headgasket went back in? standard size or thicker?

having actually bought and imported 3 X R35 GTRs from japan I do know what I'm talking about. that particular ad is for a car THAT IS ALREADY SOLD at auction to a buyer in japan. it doesn't exist any more, so you cannot buy it. as I said it's nearly impossible to find a car that is over a year old but still brand spanking new (has to be to be eligible for import approval). If you do somehow find one expect to pay around 8mil yen for it (around $100K just for the car) the taxes I listed are accurate and cumulative being 5% Duty, 10% GST and 25% LCT on the value above $57K. Add to the fact that I don't believe anyone will still comply one (but you'll need to check that) and even when they did it was approx $10K and you have no chance of buying one in japan, importing it and then complying it for $110K on the road. If you honestly think you can, please get one for me too. In fact I'll take two! who wouldn't want a brand new JDM car for $110K? you'd be mad not to.

very good actually. the US rules have nothing to do with australia and it's perfectly legal to import, comply and register R33 GTRs in every state in australia...

did you at least get your stuff that was on the back seat back?

yeah it's pretty bad and doesn't bode well for the future of the sport that's for sure. there certainly has been a battle in circuit racing too as a lot of the odle worlde crowd at the top of the heap had a big interest in keeping things nice for old cars. and simultaneously making it tough for affordable, fast, modern japanese cars. but with the big breakthroughs made in drifting, and with rising popularity of events like superlap etc things are definitely improving. and there is no doubt it's fun.

you realise that by 'ladies that hang at the shell servo' he actually means 'fatz'.... nasty but true.
