Simple questions guys coz i dont know. Thanks for Help... :)

Are rb26 coil packs much better than rb25det(series1) coil packs?

Can you put rb26 coil packs on a rb25det(series1)?

What coil packs should i get for my rb25det(series1) because they are my week point now, its breaking down now that i can run more boost with my hi-flow turbs..

thanks again,

Fane

there is nothing wrong with the std coils when they are working, the cheap option is to fix your ones. If its breaking down at higher boost but fine at lower boost, chances are the pack(s) just have a tiny crack in the housing. You can fix this for nothing with some electrical tape.

Splitfires are great, but for a hi-flow application are not a neccessity, and i wouldnt spend 600-900$ on a set if i didnt have to!

cheers for the responses guys...

sly33: its slightly breaking down but its not like when the plugs start missing whenm you havent gapped them close enough....its very soft....could it just be the AFM maxing out?

i have hi-flow turbo @ 12psi, fmic and all the usual bolts ons and a turbo back...stock afm and fuel system... what you reckon?

if everyone still thinks its coils...then where do i put the electrical tape?

fane, it could possibly be your AFM, although if it happens at just 12psi its a bit more unlikely.. obviously you dont have an FC or you could easily check if it was the afm.

id still give the coils an inspection, its not real hard, if you can change plugs you can do it.

So you need to find a crack before you go taping them up!

i dont have the pictures of my coils anymore... if i can remember, at the front (or back, depending on which coil) above where the rubber boot ends there are some raised numbers, its around here that you may find a tiny vertical hairline crack, mine was so small i had to put it under very good light to see it, and even then i wasnt sure if it was actually cracked, but i ran a couple layers of tape around the coilpack body, covering the crack, and straight away it ran perfectly. The one that went was the one closest to the firewall, and the one i checked last! so you may want to start from the back one! I have heard of people finding cracks in nearly all there coils, so have a careful look with a magnifying glass.

fane mate they are all the same to answer you original question, only the rubber stem varies in length between the rb20 25 and 26 and this can be swapped over by simply pulling it off and interswapping to your needs!!!

thanks s13drifter

sly33, i took car for a drive and it starts at 12 an goes all the way up to 16

basically what my car is like is that its just a huge flat spot....HUGE, then about 6400rpm really kicks you in the ass til 7200rpm....

but i just want to know what it could be.... on my SAFC it used to just hit close to 97 and 98% on the airflow, now it hits 100% real early when the flat spot starts, thats what makes me think its the afm.....whats everyone reackon..... ps. AFRs are around 11.8-12

steve, i asked whether they would fit, because i have a 25 and i want to put them in....so in other words it would deffinately fit...

    • 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.
