I'm with Bob buy them. It is inevitable that coils on a neo will fail.

I am not usually a fan of buying parts just in case but there is almost no downside in buying stock coils for that price. Make sure you buy coils for an R34GT-t / neo RB25DET not the R33 in that Ebay advert.

Alternatively buy a can of crc urethane seal coat and give the coils a good even spray it will keep you going for a good while in most cases.

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.

I reckon I'll do my fuel pump before I get the Nistune. Which one is regarded to be the best?

The Walbro GSS-342 seems popular, but I've read good things about the Nismo and Deatschwerks to!

The walbro's are good (If you get a legit one) but only up to around 20 psi, for boost above that I would recommend either of the other pumps. What are your power goals?

Hmm, sounds like the Walbro would be suitable - I'm not looking to set the world alight...

I got the deatschwerks, hardly breaks the bank at around $215 delivered, and small like the walbro

my GSS342 is not to noisy, makes a bit of a buzz from time to time, i put rubber inserts in my cradle to stop vibration and noise(R33 Skyline).

i have a few mods planned for the year for my s2 RS4S.

walbro GSS342

nismo injectors

splitfire coilpacks

HPI FMIC

z32 AFM

TD06H-20G (internally gated version with replacable actuator springs - not chasing to much power)

tomei oversize metal headgasket - so i can run 16-18 psi through the neo.

ECU - probably a nistune, wasnt real happy with my powerFC.

i think that should make me a tidy 250awkw without pushing the engine to hard.

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 ....

Flat spot is the tune. Cool packs break down. Of you can get new OEM cheap, do it now, has to be done at somepoint and means you aren't risking a tuning session.

Pumps: nismo or bosch

Cat: got a highflow item?

Ebc: yes, gizmo are good value.

Air filter: new highflow is $50, check yours.

O2 sensor? Has it been replaced? Dunno if your tuner will touch closed loop anyway.

      High temp brake fluid?

      By GTSBoy · Posted

      Well, back in the day..... "race" fluids, which were essentially only really "high temp" fluids, used to absorb water more readily. So they really needed to be changed more often anyway. The coincidence of that being directly necessary along with it being what racers would do as a matter of course was just fine.

      Does the high temp fluid degrade any different over time compared to normal one? That's one thing I've always been wondering. Because a track car is going to get the fluid flushed probably way more often than every two years and will see less kilometers driven. I would think the requirements are different. I'm running Motul RBF 600 in mine. Was recommended by my mechanic before a trackday and I've stuck with it since. Hasn't seen the track since but I've kept buying and using it for servicing anyway.

      The brakes are all stock bar some DBA slotted discs and the EBC pads and braided lines. The car has brake ducts as standard but they're kinda pointed in the general direction of the brakes rather than really getting at the heat source. I guess I should hit it with an infra red thermometer after a session and see what they're at.  100%! Its just a curiosity more than anything. As I said, high temp brake fluid was such a track day rage back in the day. From people I speak to at the track and threads on here everybody has their own take on it but I'm not gonna scoff at spending a few more bucks.    OH, a quick side question - would you use brake fluid from an opened container even if the lid has been on? Eg, if you have a bottle that you opened last time you flushed, it's been tightly closed, is it still good?
