Help With Mods Before Nistune

[fritters77]

I'm Looking at getting my Stag tuned with the nistune board......And Just want to know what Mods people have done before getting it done....and also what they used brand wise...

I was thinking:

Coil packs ,Yellow jackets or Splitfires or something

Fuel pump ?

Electronic boost controller ?

I already have 3" turbo back and FMIC

Any input would be appreciated

Cheers

Definitely get a new fuel pump - Deatschwerks, Denso, Nismo, Bosch 044 and wire it directly for full voltage (with a relay - tutorials on this site) and change your fuel filter. Do you have a high flow panel filter? Whatever air filter you use check to see if it needs replacing.

Are you having problems with your coils? If not you can replace them anytime and won't affect your tune. Just replace your plugs and gap them down to 0.8mm and thouroughly clean your coils and maybe spray them with a sealant.Oviously you can run too much boost if you're on the stock turbo but a good ebc will enable you to hit max boost more quickly. I iwll be using the Link so can't advise you on which ebc.

Cheers thanks for the info.....Yeah I currently have a flat spot at 5000rpm thinking its the coils tried taping them up as well as a high temp sealant ...with no change....I just don't want to get the car on the dyno and something like that fail and have to get it re tuned later........Change spark plugs recently and re gaped them to

I've got a pod filter and in the proces of making a cold air box for it.....

Thanks again ....

Have a look at these:

I bought a set off this guy and they are in my car now. I had a set of new Yellowjackets but when I saw these I snapped them up. OEM are the best - they have lasted 15 years in my car and there are no Splitfires with a record of service that long!

[fritters77]

Thanks I'll check it out....

Splitfires or new OEM coils will be needed at some point on a neo engine however you don't need to replace them unless they are breaking down. Unfortunately if they break down under load on the dyno then that is the end of the tuning session. Your call on this one.

Fuel pump...yes.

A manual boost controller will do the job like TurboTech if you are going for electronic then Profec B is pretty reliable and not too expensive.

What plugs did you use?

Are those actually OEM coils in that advert or "OEM quality"??

They look exactly like my OEM ones (R34 neo)

I just bought a set....

Yep new in box right part number fit and work perfectly. They are so cheap I am tempted to buy another set but in 15 years time I might have forgotten where I put them!

Cool, with all the gear coming out of china it is hard to tell what is the real McCoy and what is a copy in the same casing.

Chinese copies can be bought under $100 for a set of six, plus freight

Cheaper in bulk

Plenty of mark from people like justja....etc

thanks Again for your input...

Is there any advantage going Splitfires over the OEM's........i know the splitfire website will say they are heaps better,,,,,,

[KiwiRS4T]

No unless you like blue. They are heaps better than 15 year old OEM but as I say the OEM ones have the track record. Not saying there is anything wrong with Splitfires.The main reason people bought Splitfires was that they were half the price of OEM but the ones in the link are even cheaper than Splitfires (or Yellowjackets) and at least two forum members (including me) are happily using the linked ones in their cars

[wolverine]

No known advantage of OEM over Splitfires or vise versa.

I'm in a similar position. I have a Greddy BOV that was removed for an inspection. Is there any benefit to reinstalling when I get a Nistune?

[fritters77]

thanks for your help again fellas ,,,,,,,,

Has your car lost 50% (or any) of its power since you went back to stock ?

If it was plumbed back you could put it back as it is presumably quite new but if it was venting to atmosphere I would be inclined to stick with the stock one and sell the greddy to someone who wants a noisy bov.

[QWK32]

The flat spot at 5000rpm is in the stock tune, it will still be there even with new coils. The stock map drops a few degrees of timing at the 4500-5000rpm mark then adds it back in around 6000rpm.

Just echoing what the others said, get a good fuel pump and change the fuel filter. Get a boost controller, manual or electronic. Unless you know for sure you coils are dying I would leave them.

I don't believe there has been any power loss since going stock... If it isn't going to provide any gains the I think I'll steer clear. Don't want to attract any unwanted attention from the fuzz

Thats good to know,,,,,,, Is there a way that i can test the coils to make sure there fine because as i mentioned i don't want to get the car on the dyno and have one of them fail.......then buy new coils then pay for dyno time again......

It just seems like a pretty common thing to go on the RB's........whether its now or in 12months time....i could be wrong.........

cheers
