Well, you'd want to go with a brand new actuator, rather than something secondhand. You've probably all seen the pain and anguish that SR20 owners go through when their VTC actuators shit themselves. Nothing available 2nd hand because they fail so often, and new price ex-Japan + 3 week wait is not pleasant either.

You could possibly do something with a $2k budget and a new actuator included. You'd not be able to do it without a capable ECU though. So that would add cost for some people and stop others from doing it at all.

As long as the actuator is robust, such as the Neo one, I can't see why a second hand assembly can't be used. You don't see Neo's smashing valve gear...

The VCT window can be actuated by many products on the market can't it? Not a big task anyway.

Making sure you have the valve clearance would be the big stress.

I thought all the talk was about using VQ style actuators to gain the full VCAM experience. If not, then using RB issue stuff would probably be OK. But then I would just save the pain and use a Neo head.

Someone needs to do the unmentionable and put a neo head on an rb26.

Higher comp and vct with e85 would be awesome.

There had been mention the neo head can suffer shim spitting at high revs but that can be sorted cheaper than fitting vct to a 26 head surely?

a switched set up wouldn't be hard, RB VCT solenoid and inlet actuator, tee the oil pressure sensor for oil feed, rpm activated switch. Hardest part would be blocking the oil feed for the front cam journal and routing and drilling for the solenoid in its place. You would want a TIG on hand just in case you drill in the wrong spot!

continual variable would be a challenge, since you need to add cam position sensors, a better solenoid (PWM), actuator and an ecu that not only has target cam position, but that can actually control it and do so within 10ths of a second

It's been done with a Haltech already, I am sure most high end ecu's could easily manage it. You would want a good tuner though.

done, Racepace, many moons ago. No E85 at the time though.

I have my HKS Vcam controlled by my Link, so no HKS electronics, it's a bit of a mongrel (like me! lol) but it's a sweet setup. There is a hall sensor to detect cam position.

I basically gave a bunch of parts to Trent and said "fix it fix it fix it!" :D

Ah, it was yours I was thinking of Daniel, I thought you had a Haltech for some reason.

I seem to remember Trent being worried about valve clearance, do you know what degree advance/retard you ended up getting out of it?

yes, obviously a lot of care was taken with that as Vcam was added post build.

I have the type a, step 1 or whatever the first 'stage' Vcam is as my pistons are supposedly N1's, so effective stock size (?), meaning advanced/retard options aren't maxed out to what the other Vcam options can do

There are at least two motors getting around that have had it done... and that was over 2 years ago now. So likely there are quite a few more now that have gone down this road.

From memory the hardest part is an adaptor to get the RB26 intake into the NEO.

So yeah, definitely not unmentionable or uncharted territory :D

Cool.

As usual someone has always done whatever is thought of!

    • My dream is also to have a proper hoist, but I don't think it will ever happen. My quickjack is probably as close as I'll ever get, it really is very good though. 
    • Yeah we keep on in the dailies, it is pretty poor how many animals get hit and the driver leaves without checking....have saved a couple of little ones over the years. Bit of a gruesome job though, pouches generally need to be cut open because they are so tight and often the joey doesn't realise mum is gone so they are still locked onto the teat. I checked the modules in front of the DS wheel where an oil cooler should go.... There is the radar unit - that can go for race use) One of the 2 HX water pumps, the silver cylinder. That needs to be kept but might be able to be relocated But the bad news, the big computer mounted vertically in front of the wheel (blocking any potential air exit) is the electric steering computer. That is required until/unless i do a hydraulic steering conversion, and in CAD based modern car design it is not like I can just pop a big unit like that somewhere else (plus the loom would be too short anywhere else too). So, the passenger side is OK to clear out (just use a smaller washer reservoir, potentially elsewhere), but the DS no beuno
    • Well, all the best with the new camry It was interesting to hear about the UK process, it is generally a lot more streamlined here with a shipping agent looking after all the import side (noting the exact final price can still be a surprise.....) and I've used a few different brokers on the japan (or US) side, and never had any trouble with any of them....luck of the draw I guess. You mentioned you didn't get the auction sheet (understandable since you bought it from a dealer, not auction), but I always try and get hold of that because they are pretty thorough. I've imported 2x R grade vehicles over the years and both were fine, repairs in Japan are pretty thorough compared to here in Oz.
    • BTW I measured the jack I have, it is 70mm at the saddle but you only have about 700 until it returns to 150mm high at the cylinder so it is good but no magic bullet.
    • My experience with Rising Sun Exports Before agreeing to the sale I tried to do as much research as I could (obviously), his Facebook reviews are 98% and he goes Live at least once or twice a week. I contacted 2 people in the UK who had used him for their imports, both had positive feedback. His explanation and talk through of the import process was thorough, answering any query no matter how stupid it was. It felt as soon as the money was sent, communication dropped off. I asked for shipping updates every 2 weeks or so, not wanting to pester him, he never had any updates. I wasn't informed the car had been dropped off at the port, I only found out by his Facebook story. I asked for the photos taken at the port, knowing he would need some for insurance purposes. I received a few 5 second clips and that's it. When asked again, he said his staff had them. Weeks later I asked again, he tells me he doesn't have any, but does have 50 photos from the original advert. I never received them. I eventually got the documents sent via WhatsApp after I mentioned the port was requesting them. I purchased a CarVX report, to find out the vehicle is a Grade R with recorded accident damage, first recorded in 2017 when it was first auctioned. He never told me the grade, then again I didn't ask. His response was "Grade R means nothing, it wasn't chassis damage". Still, I would have liked to have been informed about it. Jon prides himself on being open and honest when it comes to inspecting cars, it's his main job doing so at the auctions for customers. When the vehicle arrived in the UK I noticed a few little cosmetic issues. It's a 21 year old car so it wasn't going to be mint condition. The side skirts are cracked on each corner and the sealant is failing. The front grill on the bonnet/hood isn't secured very well, mounting studs are missing. Both minor things, but again, it would have been nice to be told. During a Facebook Live walk around video of the vehicle, he mentioned it has a front Whiteline anti roll bar/sway bar. While on the inspection ramp, I noticed the stock item has been installed. When first questioned, his response was "the ARB? Switched? Since when, it never had them". Since sending video and photo evidence I've not received a response. I'm probably being over critical of the overall condition of an old car, but all I wanted was honesty (which he claims to have). I'm aware I wasn't his only customer, he's busy doing XYZ but other reviews praise him for great communication with regular updates and photos, I felt I didn't receive the same treatment.
