I haven't had an issue with my stock VQ coils at 40psi, there is obviously something wrong with your setup if you can't run more than 21...

Are you running a wideband? Most likely the mixture is just too rich and it's flooding under boost. Otherwise, drop a set of VQ coils in there. :P

I can't see why not, might need a little modification. I can test one out on the 34 here if you like, and see how it fits...

You may need to adjust the dwell from RB specs, not sure what mine is running though.

That would be a great investigative pursuit haha!

I fitted a VQ coil to the Neo 25 today, the loom plugs straight in (not sure the pins are the same yet.) and the lower section can be swapped to some extent, although the 34 lower insulator is larger where it joins to the coil. No big deal fitting them I suspect.

A bracket wouldn't be too hard by the looks of it either.

I too noticed the loom plugs looked about right. So in theory they should work by the sounds of it, though your in the best position to find out haha.

Have been doing some searching for info on dwell time etc, with little luck. Must be hard owning one, as there is little about them.

There is so much more information around on VQ25det's now, compared to when I got the Stagea 6 years ago, mainly due to my own r+d. :P

I have the workshop manual, and have translated the ecu pinout diagram, so the plug pinouts are easy to check. Other than that they should drop in using the lower insulator of the rb coil, perhaps with a cable tie or similar around the upper section.

Maybe mate the two insulators together rb lower to fitt the head and upper vq to fit the coilpack.

Other than that, grab some toyota pencil denso coils (from a 1z-zfe?? or similar). Built-in ignitors and the supra guys swear by them.

1ZZ-fbe is the engine you want. :P

VQ coils have built in ignitor also.

If these plug straight in, it's a no brainer. The only time I have had misfire is when the mixture was under 10:1 on ethanol and it wouldn't ignite well due to the plugs being wet.

Hey everyone.

What is the most powerful bosch coil you can get? (Part number)

Currently running 717's and on e85 I'm losing spark over 21 psi.

Don't have the cash for big money ignition at the moment just want a cheap upgrade so I can bump the boost up a couple more psi.

What plug gap are you running? I had a miss at 0.8 so went down to 0.65 and all good.

      S1 Autech 260RS Wiring Diagrams

      By ARB26 · Posted

      Newbie here, proud owner of an Autech 260RS. I'm on the hunt for wiring diagrams specific to the 260RS, particularly S1. I've ran my eyes through R33, R34 Diagrams, there are some similarities, however continue to find incorrect wire colours and pins on connectors in the 33,34 diagrams.   I was hoping someone could point me in the right direction? I'd be happy to pay for the originals in Japanese. I can translate them, at least they would be accurate.   Any help please would be greatly appreciated, never heard an RB26DETT before let alone driven one, and I've got a spaghetti monster of goodness to sort out.   Cheers Benny

      Tein Circuit Master- rebuild worth it?

      By QB6SAGR · Posted

      Thanks guys,  Yeah I should at least have them dynoed, at least then I know what I've got as a starting point.  The springs on these are hard as rocks. I vaguely remember Russman saying he was going to sell the shocks to me with the rocks fitted, as he was keeping the softer springs for his new setup.  I didn't click at the time but of course that was to let me know the shock/spring wouldn't be matched.  I also remember pricing up new springs around 2014-15, but, house, money etc. it never happened. So that was another reason to have them rebuilt. I have rebuilt the forks on many motorcycles so I think I could handle the seals on these easily enough, but getting the valving right would be a rabbit hole I cbf exploring.  Duncan, interesting to hear RP was tuning these back then. I might give them a call.  In the mean time I have been busy fitting sway bars. The Whiteline rear sway bar I purchased 15 years ago finally got fitted, along with the Whiteline front bar that showed up last week. Just waiting on new links for the front sway bar to finish that off.  And my spare set of advan AVS VS5's should be back from the powder coaters in a Pearl White finish sometime this week, with a set of Hankook RS4's lined up for fitting.  And then I just have all the suspension bushes to do. A comprehensive kit is on the way... Lots to do before the Ararat hill climb. Cheers guys 🍻
