Tomei Pon Cams S2 Rb25

[Ad's]

Ok before i get flamed i have read and searched alot about Tomei cams on this site but haven't really found the answer i was looking for, im wanting advice from the people that have done cam changes and wished/changed out other parts the same time.

Ill be purchasing some cams in the next couple of weeks and i was wondering if i should replace anything else in the head whilst I'm changing them over? Seen as these motors are getting on in there time would it be ideal to change the hydraulic lifters? Obviously the o rings and the cam oil seal get replaced but would you replace anything else? I work for Nissan so getting genuine parts for cheap isn't a big deal unless people recommend aftermarket brands to be better!

Would adjustable cam gears also be a good idea too whilst changing cams?

I'm pretty much building the car and motor over a few years so time doesn't really matter. I'm looking for 300kw but on a safe tune of say 250kw i know people will say don't bother with cams with that low power spend your money else where, but I'm trying to build something a little different with as much mid range as i can get!

Atm i have:

Apexi power fc

Z32 afm

FMIC

3 inch exhaust

040

Splitfires

Garrett 2871 with a op6 rear housing that I'm going to get rebuilt and highflowed again to the specs of a 3076

Next:

Tomei pon cams 256 degree duration and 8.5mm lift both inlet and exhaust

6 Boost manifold with external gate

Nismo 555cc injectors

Adjustable cam gears?

Probally a few other things i have forgot too.

What else can get me more mid range over raw power?

Criticize my set up people and give me some feed back.

Any help would be greatly appreciated

Thanks

If you are after midrange and somethimg a lil different run E85 if you can get it easily enough you will get fatter midrange and more raw power

[Ad's]

That has crossed my mind but it's atleast a 50km drive to the closest petrol station that sells it!

[Mick_o]

yeah that sux if its a daily driver E85 as you are limited to where you fill up but with a link ecu and an ethanol content sensor you can run 98 and E85 but $$$$ needed tho

[Ad's]

Nah not daily more so a project garage queen haha! Still it's abit of a waste of fuel either in the coupe or the daily just to get fuel to go for a drive in it. 98 is good enough for me

[NYTSKY]

Mate, I drive 55kms to get my E85. A worthy trip IMO

[PM-R33]

I would happily drive that far also lol.

Don't bother with the cam gears or anything else. Valve springs would be the only other suggestion. Some people do them with the head still on. I just decided to take mine off and rebuild it.

[Ad's]

Haha it will be a fair drive for me once i start living out of home! You recomend genuine valve springs or some type of aftermarket ones?

Thanks

[PM-R33]

The Performance brand are good value for money. Many people use them. Or the Tomei springs.

[snozzle]

Wow.. if the only problem from getting e85 was that i had to drive 50km to get it. id be on it now!!

E85 is 5 mins from my house and i still found the range anoying for a daily driver!

[Ad's]

I wouldn't care driving 50km in my situation atm! Just when the rentals move out next year and the mrs and i move in i know i will have bugger all money to drive 5 min down the road for fuel! Ill price up new valve springs on monday PM-R33 and compaire the difference!

Any other recomendations?

Cheers for the feed back guys.

[Mick_o]

Yeah E85 is 1.2km from my place haha!

so in the next 2-3 weeks when my turbo and injectors fuel pump and regulator all turn up my car will be on eflex cant wait

its closer than that here, just costs $3/L and has to be pumped by hand....

[PM-R33]

I'd suck it out of the bowser if I had to..

[snozzle]

E85 for $3 a litre for a daily driven car is pretty much pointless. Only 5% of the time im driving the car will i need the benefits of E85. CBF with drums hanging around my garage/house either lol.

Id probably pay as much as 1.50-2.00 /L if it was at the bowzer.

How much is Eflex over east?

[Mick_o]

Last time down at my servo with E85 it was $1.26/L and before fuel jumped in price bout 6-8 weeks ago id say the eflex was $1.16/L its cheap for 105ron i think??? or is it 108ron?

+1 dw aboth the cam gears snd definately do the valve springs and while your there do the valve stem seals and rebuild your lifters as its easy to do then bolt up and will have no problems.

[Ad's]

Cool thanks guys ill have a look at genuine prices tomorrow!
