Ikeya formula sequential shifter

PEPI · 02-16-2014, 08:38 AM

Hi all.

For a long time, when ever I have had the opportunity to drive a car on a track with a sequential trans - I savoured every moment of the experience - I would jump at the chance again and again.

What are people's personal opinion regarding Ikeya formula sequential shifter?

Can you shift slowly with it, or is it going to slam into the next gear every single time even when you are just driving around town? I've never seen one work in person.

its just an h to sequential adapter shifter, doesn't relapce the synchros or anything. i used to be in a club with a guy who had one on an fc and if you moved the lever slow it engaged slow, didn't improve shift quality at all just a different way to shift. the only real bolt in sequential for our cars is the quaife qbe69g and last i checked it was like 11k

Sequential shifters that are hand-operated are a WOFTAM .... UNLESS you are in a race car, equipped with a dog-box (dog-engagement rather than syncro) - you are better of getting a AT7 and playing with the paddles - the ONLY thing a H-pattern to sequential shifter on a Z34 would give you is bling/bragging rights.

Some folks might think that is reason enough, and good luck to them.

My race car (not a Nissan) has a Holinger H-pattern dog box and it works just fine, albeit that I have ordered the sequential shifter upgrade so I can flat change AND because I need to avoid a wrong-slot which H-patterns are prone to.

Since I upgraded the engine to full ECU control for last seasons, and picked up ~100bhp (went E85 and 14:1 compression at the same time), flat-changes on the way up the box becomes necessary as I am chasing GT3 machinery and they all have either sequential stick OR paddle shifters and this is worth a bit less than a tenth per change and that means a lot to me - equates to (relatively) cheap lap-time improvement.

If you want one, get it, but it only delivers Bling/Bragging rights.

That Ikeya shifter reminds me of the old Hurst Vert Gate shifters that dragracers use. LOL The Quaife tranny is the way to go.

yup basically, a quaife with the air shifter option and the gear position sensor is sweet. but that costs over 15k and you need a motec to run it.
