What To Do First....

[lanky71]

Ok,

I am extemely happy with the R34 GT-T Sedan I have and its stock apart from the body kit, but I figure upgrading parts can't hurt.

I was wondering what to do first, been looking at a 3" exhaust system from the turbo back but it is going to work out at approx $1600 so the first upgrade whilst I put money a side for that... what should it be?

BOV - Get a cheap BOV to help with the Turbo turbine - this car is an Auto but been told bov's still work on them....

Air Filter Box - Upgrade from stock

POD Filter

I really am a novice at this whole arena so I am trying to learn but would like any suggestions or feedback you guys/girls have.

Also if I upgrade a part and it means something else needs doing can you also post that... wouldn't want to ruin the car

BTW: The installs would be done by a professional not me.

Drew.

theres quite a few posts out there on sau that has covered this already.

1st thing id suggest is fix up the intake and exhaust. pod, dump pipe and a good exhaust will give u a better flow and way less restriction. it will open the motor up a lot more. bov shouldnt really be needed straight away til more boost is added

[mad082]

first thing to do is the exhaust. no point doing the intake until you have made it so any extra air going in can get out.

as for the bov, don't waste your time. it is an auto, so it doesn't dump on gear changes, unless you lift your foot each time it changes. and the stock is more than fine for boost more than what it is safe to run the stock turbo on.

I'm running stock bov at over 250rwkw.

Exhuast is first. 3 inch turbo back. Try to get a split dump/front pipe. Make sure you get a decent cat.

Panel filter in the stock air box is next. I still have the stock airbox. Nismo, apexi, pipercross and others make good replacement panel filters. kudos motorsports on this forum sell the apexi ones cheap enough.

Sorry to hijack this thread.

I know that the stock bov is well capable of handling the stock turbo but what about an aftermarket turbo? How much boost can you actually run through it? Or is it just as simple as upgrading the actuators to have more boost?

[GTRgeoff]

I kind of agree there Ron, but pods are a pain, and the standard panel can flow plenty with the right airbox mods.

Wait for my tutorial on modifying the airbox and concentrate on a decent FMIC. Saves noise and money and heat from the police, plus you need to shield it properly. I run 260rwkw through mine on the GTR33, same panel on all Skylines.

Do the exhaust from the turbo back. Look for second hand, $1600 is way too much. Even new catback from Nengun and a Batmbl or Flyn front pipe won't cost that.

Don't do the BOV. Wasted on an auto, totally!!

Being an auto a PFC might be too harsh for the gearbox on changes so look at the Autospeed digital fuel adjuster and boost controller. Look fro Sydneykids thread on them.

[mad082]

for exhaust, you should be able to get a full 3" from turbo back for under $1000. UAS do the full kit for about $900.

Ok, That answers alot of questions straight off.... Well thats it first thing is the exhaust system and probably at the same time the intake bits....

I was talking to "Satanic" about the exhaust system quote so I think that he would use the good parts and know what to do as he did the work or some of the work on your car "abo bob"?

I was just double checking that there was nothing really minor that needed doing, figured get it out of the way first.

I will leave the BOV then, figured it wouldn't make any noise anyway like mentioned above with the "dumping" of the pressure. So thats good.

Thanks, will keep an eye out for your tutorial, did a search for user sydneykid but could not find him so I did a search just for that name in the threads and came across this:

UAS CAT BACK EXHAUST FOR SKYLINE R33 GTS-T

3 INCH HIGH FLOW EXHAUST SYSTEM. DOES NOT HAVE RESTRICTIVE INTERNAL PIPE IN REAR MUFFLER, USES 20% LARGER RESONATOR & FULL STAINLESS PIPES WHERE MANY JAPANESE SYSTEMS USE STAINLESS REAR MUFFLER ONLY.

Is this the system you were talking about mad082?

This is the rough quote I have already:

3" Dump Pipe; 3" Front Pipe; 3" high flow cat; and 3" cat-back exhaust. On turbo cars; we have found that 3" systems are the best for flow and performance.

All up if you buy this exhaust as a kit you're looking at $1100 for the exhaust bits; and another $400 for the high flow cat. Installation you're looking at another $100-200.

In that quote it is stated that, that is retail price and that no one pays retail so obviously they can do better but do all kits contain the above mentioned products or does this one have something extra.

Hey lanky71 I am also in the same boat as you. Although the only mod on my R34 sedan (also auto) was the 3" Apexi cat back exhaust. First I changed the panel air filter for a K&N because this is the easiest to do I guess. Next will be the split front/dump pipe from turbo and high flow cat. Then a FMIC will probably be on the cards. Just remember you can only do either a FMIC or a pod filter, not both, but you can have a panel filter and FMIC. Also the suspension upgrade will be somewhere in there as well.

Why is it there is an endless list of things to do??

I must go and water my money tree and stick it out in the sun!!

GTRgeoff I will be looking out for your tutorial on modifiying the airbox too when you have posted it!!

[mad082]

the intake mod laws limit you to 1 mod, but that isn't in all states.

then go the cataogue section, then skyline, then exhaust. about halfway down the page is the xforce system. it is the stainless system for $980 for turbo back.

[Abo Bob]

He's a mate of mine but he didn't do any work on mine. He got a split dump which is a copy of my CES one and cost half the price.

Ok, that was going to be one of my questions. With so many cars be defected how do I know that I won't get done just because the police officer is in a bad mood or something even with just one mod.

Ah, yes I see it now. It says for R32/R33 but I am guessing that it also works on a R34?

Ok, noticed in another thread he was stripping your car and selling all the stock parts. Just assumed.

Still got to wait like another 3-4 weeks before I will be ready to get any exhaust system but at least now I know exactly what I need so I can take a look around.

Is there one brand over another or over all the others that you guys recommend?

Drew.

[mad082]

forgot it was a 34. better double check that.

as for brand, there isn't much of a difference between them. the only difference in the brands really is how well the mufflers work, so how quiet they will make the car.

EDIT: i think the r34 is slightly different to the 33, but xforce does do a r34 system.

I'd highly suggest getting a split dump from BATML, also if I was to do my exhaust again I'd put up the extra cash for a stainless system. Mine is already rusting

I guess no one sees it though.

ehh sorry also hi-jacking the thread :\ but why cant u have a pod & a fmic?

thanks guys

It's a regulation thing in some states (not SA). One intake modification.

As quoted by mad082 as well "the intake mod laws limit you to 1 mod, but that isn't in all states."

I am not sure on other states but I think in Vic you are only have one intake modification, either FMIC or a pod filter. Each is a separate modification = 2 modifications!! But an upgrade to a decent panel filter is not classed as a modification as they fit straight into the original airbox, therefore you can have a FMIC as well. You should probably check the state rules as to what you are allowed, rather than find out the hard and expensive way.

This is my understanding anyway, please correct me if I am wrong.

[Scratch]

A tuner here in perth mentioned that stock airboxes are good for up to 400Hp anyway. pod's were originally put in because the stock airboxes wouldn't fit once a FMIC was installed, piping and all. Eventually that message got lost and the ricerboys put on pods for the "fully sik sucking noise" *chuckle*

Does your 34 come with a stock bov? (let me know even if its a recirculation valve)
