S1 Stagea Coils

[JustinR34]

Hi,

Looking to replace the coils in my Stagea, I've got some yellow jacket coils from a spec2 R33 GTST which I tried to fit in my S1 Stagea but it didn't run right and overheated the trans? I don't know how the coils related to the transmission overheating but that only happened when the yellow jackets were fitted.

I was looking on Nengun and it shows the coils for a Stagea being different from R33 spec2 coils, shows them as being the same as R32/R33 GTR coils. Can someone confirm this is correct as the listing on Nengun also shows the engine code for the Stagea as RB25DE.

Thanks

That Hitachi chart looks wrong. Yes DE and DET are the same but should be the same as R34GTR not R33 GTR

Ref their Splitfire chart instead. You need SF DIS 005

or you can get then in Australia from:

BTW the Yellow Jackets for S2 R33GTST should have fitted your S1 Stagea (although they could have been faulty)

ref YJ RB2526-S2

Thanks for the reply, will try another set from a mates R33 spec2 and see how it goes.

I'm in the UK, I asked on here because you guys know more about these cars than the people over here do.

There's no way that the coils could affect the trans temp.

It was missing really badly so maybe that had something to do with it. It didn't do it before I put the yellow jackets on, hasn't done it since refitting the original coils.

You can recognise the correct coil by the mounting holes - yours should be like the first pic (DIS 005)

[JustinR34]

Excuse the crap pics, the coils I removed with the ones I replaced.. trying a different set of yellow jackets tonight.

Hallo bud, as above, the spec 2 r33 gtst coils should have fitted. (You do have s1 rs4?)

Where did you get the yellow jackets from?

They're not necessarily the cheapest but autoextreme can sort you out some decent ones.

Just whatever you do - don't get benchmark ones! I know of more sets that have failed than work lol.

just get standard coils from kudos motorsport. they are the same price as splitfires.

Yea it's a S1 RS4

I can't remember who I bought them from, a UK based tuner probably - would have been about 4 years ago.

Will give autoextreme a look, thanks.

I've never heard of that brand lol. I've been on skylineowners for a while so tend to read up on stuff there, it's just people on here know a lot more about the Stagea.

I'm in the UK so import taxes would make them more expensive.

I put a different set of yellow jackets from my mates R33 in which ran fine but I think the plugs maybe part of the issue.. It'll accelerate fine for the most part but will have a rapid misfire under boost/hard acceleration. I'm going to double check everything else that I've messed about with too (loosening of pipes to get at coils and the 2 stage high boost mod).

If you are using copper plugs they should be something like NGK BCPR6ES but whatever gap them down to 0.8mm. To properly check for boost leaks make up a plug and pressure test to about 20 psi. If its dying under hard acceleration it could be R&R (look it up if you are not familiar with the term Rich and Retard) caused by too much boost.

Out of curiosity, how did you come to the conclusion that your trans overheated?
