It was all done as part of one big package (RB30/T76) so not too sure... Not too sure what sort of benefits it would make by itself, but they are a fair bit bigger than the baby cams that are in there to begin with.

Definitely need to get the cam gears too if you plan on doing this.

Hope you guy's know what your do'in,cause to my knowledge the RB26DETT uses solid (shim type) adjusters & the RB25's use hydraulic lash adjusters.If you work it out,I just so happen to have what you're looking for,plus a lot of other GTR bits,so do some research & tell me what they're worth(sensibly) & I might part with them.

I've looked into this a little and it appears that you can put solid adjusters into a GTS25t, but you can't put the hydraulics into a GTR. I'm not too sure what they're worth yet, but I'll check with the Toy Shop. They've got absolutely every part known to man and if they don't have it they can price it for you and then get it.

How do you think it'd go if you got a GTR cam and adj cam gear for the exhuast side, and keep the factory inlet cam so you can keep the VCT in the inlet side of things?

Would it work OK or would it be too much of a mismatch in inlet/outlet cams???

Hi guys, the standard GTR inlet camshafts don't have the drive for the VVT, so you can't use it. From memory the GTR inlet cam is hardly any different in timing or lift to the RB25DET. You may get a little bit out of the exhaust camshaft with an adjustable pulley. Maybe 5 to 8 rwkw, but most of that will come from the pulley.

I don't really think it is worth the effort.

Series 1 RB25DE cams are quite a bit more agressive in both timing and lift, I reckon they would be a better bet than GTR ones. Plus you can use the hydraulic buckets. But you still have the VVT problem, as the N/A engines don't have VVT.

We used these cams in the RB30ET/RB25DE hybrid for 475 bhp on the engine dyno in our old GTR, so they are certainly OK at that level.

Hope that helps.

I'll be interested in the results.

Hi SydneyKid,

I had a look at the image that Meggala posted ages ago and got these specs for the cams:

RB25DET

IN EX

240 240

7.8 7.8

120 117

RB26DETT (R32, R33)

IN EX

240 236

8.58 8.58

113 125

Do you know the actual specs of the RB25DE cams? It would be good to use hydraulic ones.

I thought the GTR cams would be good as they are close to the RB25DET cams, but with higher lift. For $250 I thought it was a bargain.

SydneyKid - I was hoping that you'd reply here :D

Can you see any problems using only the RB25DE exhaust cam (with adj pulley) in the RB25DET and keep the original cam so you can keep the VCT??

Or would you rather use just a adj cam pulley on the stock RB25DET exhaust cam and not bother using the RB25DE cam at all - just talking about mild mods, nothing serious :P

Cheers

Jayson

    • Thanks for doing that Duncan! Makes you a good person in my books. We don't get kangaroos or wombats here. But we have bats and it's similar. AFAIK it's often the mums with a baby attached that get hit because they drop lower when starting from a tree. If you hit an animal, check on it. https://www.ifaw.org/au/resources/wildlife-rescue-app An app to get the closest wildlife rescue contact.
    • 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.
