Nismo Coppermix Single - Reviews/opinions

[NISMO]

Hi Guys,

there's heaps on here about the coppermix twins, but not many reviews on the singles.

I've read the NISMO brochures and know that they're good for around 420ps, but am hoping someone has one in a GTR that can give me a bit of info and their thoughts.

Being a fairly stock car, my 32 putts around with about 280 rwkw on high boost which is rarely used. I'm actually thinking of removing the boost controller all together and just going with the stock solenoid so i think power wise it should be ok.

At the same time though, i want to be sure it'll do the job for years to come, even if i do decide to punish it every know and then. Have read a fair few reviews on them being used in higher power S15's and S14's but am curious about how they go in an AWD

Please no "speak to Jim Berry" comments. I've got one in at the moment and am not happy with it. Just my personal taste.

The twin will be overkill for a stock car, so no point spending the extra k ( or close to)

Cheers

I've got one, not a gtr though, rwd 25 300+rwkw, works perfect for me, reasonable on the pedal and has never slipped

Thanks Alan,

read somewhere that they're quite noisy?

No worries, no not noisey at all, I'm very happy with it, did read a while ago it was the strongest single?

I had one, felt like stock (thought it was stock until pulled it out and got a surprise), took a beating and never had any problems with it. Used it to 262rwkw, never slipped once. You'll be very happy Bobby, go for it. Send a PM to elrodeo666 for buying one - he's a fkn legend and you wont find someone who not only has them cheaper but more importantly he keeps you updated throughout the process from start to finish.

I have to say though, I went from the nismo single to the nismo twin version, didn't regret it at all. While i understand the cost difference, they drive very similar and the twins are so great on a dirty great big launch for when we finally get you on the skidpan

Thanks Guys,

haha, Steve i did have a bit of a play at a texi a few years back ( 1 run with a 3500rpm rev limit )

Yeah i spoke to Marcus last year and will def go with him if i go ahead. His prices were by far the best!

Little bit of extra rattle from the lightweight flywheel, as expected. But nothing extreme.

Mainly on idle and through low RPM range.

You may have heard that in the product warning - http://www.nismo.co....tch/lineup.html

• The sports clutch discs and light weight flywheels, which are designed and manufactured to increase capacity for higher output and to improve clutch response, may cause the transmission or bearings to make a rumbling noise which is not present when using the original Nissan production parts. Such noise is particularly likely to occur when idling or when accelerating and decelerating at around 2000 rpm. Please be aware that this rumbling is not due to any defect in the parts.

/\ mine doesn't rattle at all, does say it may do in instructions though

I've got one in my S15 with a 26 in it. Rattles like a bitch from 2000-2400, I thought I had damaged the gearbox bearings but it seems like this noise is common
