R33 Gts25t S2

Lads,

Due to some advice received on this forum i had a split front/dump pipe installed (already had nismo catback 3" high flow cat etc) and upgraded the panel filter to a K&N High Flow in the standard box. She now has a good quality turbo back exhaust, 34 SMIC.

Seems you guys were correct im really surprised with the response the car has with such a relatively basic mod. Car seems really alive and responsive and has a better top end. I was more than impressed to be honest and now im pumped for more...

What are my options that will give a good result without spending nearly 2k on an APEXI POWER FC. Are there any? I want to run 10spi safely (currently on factory boost etc). My AFR when initally dynoed ran down toward 10:1. Apparently this is pretty rich therefore safe? i want to keep it this way as reliability is a high priority (its a daily driver). I have apprehension in simply purchasing perhaps a dual stage boost controller and winding it up a bit. Ive been reading the forum as much as i can, and i hear this may cause flat spots due to fueling issues and spiking etc, and is a dodgy way of doing things??

I guess if ultimately the PowerFC is the only way to go ill do it (but spending the cash is hard to hide from the missus.... shes not a fan). Is there anything middle ground. Im not after 300 KW ATW. 200 will do....

Any advise is appreciated, so far its been dead on the money and much appreciated.

Matt

Hey dude. Glad your a happy camper!

Did you notice any boost spiking with the split pipe?

The best thing you could probly to without going FULL ECU (Power FC etc) Would be an SAFC2 piggyback. I have just put one in my R33 and am awaiting a tune. Will tidy up the AFRs and give you a little more midrange and top end.

If you want to run a safe 10Psi all day every day, go out and grab yourself an R32 GTSt Actuator. they have a 10Psi spring in them. So you can do away with the stock R33 boost solenoid alltogether. I have done it, and so have alot op people. Works very well!

Hey mate

if your only after 200 or so KW then perhaps look into just a manual boost T and an S - AFC

get the S-AFC (super air flow converter) tuned to sort out the A/F ratios and 10 - 11psi and you should be bang on you targeted power.

Should be able to do it all for less than the cost of a PFC

Just my 2c..

Corey,

haha great mind think alike ^^^^^

[Mattw_83]

Thanks mate!

Ive noticed no spiking. I was up early this morning, it was pretty cold and i noticed no spiking. Although ive only got the standard boost guage... i

Are these actuators hard to get?

I'm a tuner and I HATE SAFCs. THey are shit. Don't be so cheap and get a powerfc, they are much better and you will get a much more desired result.

In the end, you're still paying for a tune. Whether it be a shitty SAFC or a powerfc.

Spend that little bit more and do it properly. You'll be able to tune the ignition maps (can't do that in a SAFC) and give it more grunt down low without causing it to ping in the top end.

Hey matt, reading your post makes me glad i made a date with the mechanic to fit front and dump pipe. Hopefully im as happy as u r. Btw same car.

Not everyone has $1000's to spend on an ECU plus another $1000 for a tune tho. The SAFC will work fine for his needs.

The actuators arent too hard ti find. You just need to keep an eye open! Or try a local Nissan wrecker

What he said. But also what gotrice said too. Not everyone has the money.

If it was me, I would skim a little off the wages every week so the missus wouldn't know, be patient while the cash built up and then purchase the unit.

Then when the bug has bitten you (and it will - it happens to all of us) you will have the PowerFC to do anything you want.

Take everyone's advice and make up your own mind, after all, it's your money.

Later man.

you say you want 200rwkw now but as you get use to the power you're going to want more!!!

I lean a bit more towards The Mafia's view on going full ECU instead of S-AFC. I guess the good thing about S-AFCs are you tend to be able to buy them used for a reasonable price and sell them for a similar price when you (almost inevitably) decide that it wasn't that great and you would have been better off just buying a full ECU.

I personally can't help but notice that the people who are saying "Get a full ECU" are people who have been down the S-AFC path, and the people who are for the S-AFC are ones who haven't had one yet or are in the early days. Hardly anyone who has gone S-AFC seem to stay with them for any real length of time. The gains are often OK but I'm not convinced they are enough to pay for themselves.

If you don't have the money to go full ECU, then you shouldn't be wasting it on an S-AFC imo.

hey mate, got the same car and same name....and the same mods.....and chasing about the same figure aswell.....bloody coincidental. should catch up sometime....

anyway, i offered advice about the JJR split front and dump pipe, and gald that u have found this to be beneficial.

as for a ecu setup......dont go and spend the money twice, jus save some more, enjoy ur car in its current power and let the bank balance pick up again b4 goin out and buyin a PFC.....i agree totally with what lithium has said....

also one other thing u could and maybe should look at would be a z32 afm......

Cheers

S-AFC's have their place in terms of a basically modded car, with mild aims - only with a stock turbo - and a budget that might not extend too far.

Once you upgrade turbo you really need to do it justice and upgrade, before that its a so/so thing in my eyes

[SLY-25T]

i would lean towards buying a PFC.

i know how u feel that u might have the money for a SAFC now and want a lil more power so u just wanna buy it, but it should be worth the wait. personally dont have a PFC but am trying to save for one. would prefer buying something that does everything instead of buying something that does a few things for now.

congrats that ur happy with the car and keep pouring money into it lol

[SLY-25T]

+ if u buy a SAFC and decide to go bigger with osme things in the future, u may not be able to due to its limitations.

if u buy the PFC, anything can be upgraded and the PFC will handle it.

[J3TR33]

you could also get a remap from toshi, i got mine from him and very happy, he is in the business trader section

or another option is the Vipec/Link ecu, i think the Links are cheaper but its the same ecu,

cheers

These SAFC's are also a shithouse to install and remove.

If you pay someone to do it, there is more money wasted that could have went to a powerfc.

Think about it... A few hundred more, and you have a powerfc and a hand controller.

What are you kidding? An SAFC2 goes for $300 Max. Install is a piece of piss, and even if you do have to pay for an install, it only cost $150ish.

So $450 all up. And your still short $1000+ for a Power FC and hand controller. Not to mention they seem to cost over $1000 for a full tune.

If your lucky they do go for cheaper but they dont seem to come up that often.

[tridentt150v]

The money you spend on a SAFC you could get a toshi/doctor drift remap of your std ecu and do so much more with it, its not a pfc, but its way better than a SAFC.

So bang for bucks as a first step is rechip imo.
