Help On R34

[GreddyGo]

Hey People's,

I've recently sold my 180sx and in the market for a R34, have a few lined up to have a look at.

I searched the forum to do some research on common problems etc. but was unable to find anything helpful.

Just want to know what to look out for when getting one of these cars, I'm also a mechanic so I know how to check over cars, but just common problems that I should keep an eye out for.

Thanks for ya help.

Cheers

Josh

I did read through that, I'm a mechanic so i'm obviously going to check the things listed there.

But is there anything in particular that goes wrong with a r34?

I.E What is a safe boost level for the turbo's and injectors,

Are the lifters and injectors normally noisy?

etc.

Thanks for your help though

Cheers

Josh

you can have mine for 25,000 i'm in SA.

Are the turbo's aren't much good over 10psi or so.

The lifters don't really make any noise not like a gtr.

Coil packs seem to go around th 60,000 mark.

some small things like that.

Yep seems like many 34 owners have the same problems with their coil packs. Apart from that dont think theres much things to worry about hance they arent that old compared to 32s which needs more attention.

[GreddyGo]

Ok great,

Sounds like there a pretty solid car then.

Keep them comin guys.

Cheers

My one has done 70000Kms now and i havent needed to change the coilpacks so it all deppends.

but its great with little mode u can fair bit of power increase

Coilpacks went in mine too... it has 120,000km on it. That's the only consistent problem i'm aware of with the R34 GTT.

[JUNR34]

I know this might sound like a newb question but what are the signs that shows that your coil pack is in need of replacement?

[GreddyGo]

from speaking on experience with sr's, slight misfire and hesitation, especially when you ease the throttle onto boost.

The check engine light will normally come on intermittently or continously...

[JUNR34]

Alright cheers for the heads up guys.

Far out... is that what my problem could be?

I did an ECU reset and it hasn't come on since then, however that was just 2 days ago. I just got a new 3" full exhaust and when I gun it it has this MASSIVE hesitation/stutter at around 5000rpm. The exhaust pops a little bit more than I think it should as well...

Excuse my lack of knowledge, but is the coil the thing that gives electrical power to the spark plugs? How much does it cost to replace these? And who would you get to do this? A Nissan dealer?

Any good way to confirm that this is the problem?

My R34 has only done 31,000kms (I do believe they are genuine - I paid big for this and have service history) but is a 1999.

Yeah the coilpacks are part of the system that delivers the charge to the spark plugs.

The cost to replace them with genuine items is over $1,000. What just about everyone does is replace them with similar coils called 'Splitfires' which are actually better, and cheaper. If you look around you can get them for $850 or even slightly less these days.

I think thats a fairly common problem with RB twin cams. the coil packs get so hot under that cover. I had about 3 fail on my HR31 (obviously cos its old), and also when it had a late R32 engine in it.

[R-sanichi]

The coil packs are as simple as changing the spark plugs. So anyone who has done that before can show you. I would, but I dont think you`re in my neighbourhood.

Are they really $1000? I remember for the RB20DET in my HR31 they were around $160, new. Are they a different unit?

Also, I have a question re: buying an R34. What options came from the factory? Cruise control, sunroof, dashboard gauges, etc.

Thanks.

Get onto perfectrun they do splitfire packs for very good prices, normally around $550 delivered.

Another problem with the auto's is the shift solenoids in the gearbox, these can start to breakdown...not as common as bloody coilpacks though! Also not very obvious until you find the car locking in 3rd gear a lot, until one day it never comes out!
