Help please advice for my 1987 R31

Are kits bad for the car or something? 

[GTSBoy]

No, just lazy. Exhausts aren't rocket surgery anyway. Anyone who can weld can knock one up in an afternoon.

Another question I have I wanted to get a 2.5 inch exhaust for my r31 just wondering if use know a good site to order them off or a certain brand..? Iv been told eBay but thought I’d ask use first 

Get a local exhaust shop to fab up a 2.5" mandrel bent cat back using two quality mufflers. Will sound nice and you might make an extra 1kW up top.

Sweet as will do cheers, another question sorry if I’m doing heads in.. I wanted to improve the air flow I was gonna do a basic pod filter but my brother was telling me to get a growler kit any thoughts ? 

[JohnnyR31Silo]

If any thing don’t worry about the exhaust just found out if I’m going to turbo my car I’m gonna need a bigger exhaust 2.5 inch is no good, would a growler kit be okay with a turbo though?

What's a growler kit?

A cold air intake. The growler is a brand by SS induction usually for commos.

[JohnnyR31Silo]

Do you reckon a growler kit would be good for a r31? Especially if I’m gonna turbo it eventually would I be able to keep it on or no? 

[trel]

If you're going to turbo keep the stock airbox with the growler. Pods are shit anyway.

What? no
best upgrades on my R31 are:
good tyres
working dampers
GTS/HR31 front brakes
manual conversion
3.9 auto LSD diff that doesn't whine
GTS1/mild cam

[JohnnyR31Silo]

@niZmO_Man I’m guessing your r31 is non turbo ?

[JohnnyR31Silo]

@trel so keep the growler kit in the car as well as the stick air box? 

[JohnnyR31Silo]

I was going to get the exhaust but a mechanic told me no point wasting money if the car is non turbo and Your planning to turbo it then a 2.5 inch exhaust is waste of money because I’ll need a bigger exhaust...? Is that true?  

[Ben C34]

Anything spent on a car is a waste of money, so yes that is true

[JohnnyR31Silo]

@Ben C34 very true, but if I’m gonna spend money I don’t want to be wasting it to much only want to get things that I need an if I’m gonna turbo the car no point getting a 2.5inch exhaust only thing is I’m trying weigh up is if the growler kit is worth it..? If I get it will it be the same thing with the 2.5inch exhaust..? If so is there anything I could do to the car that will help the air intake and what not without it getting in the way when I eventually throw in a turbo kit

[niZmO_Man]

If you're going to turbo the car, your first step would be to put the turbo on the car, and then get all the associated parts on it to support it (exhaust, injectors, fuel pump, ECU, etc)

What ever this growler kit is won't help you in that endeavour

[JohnnyR31Silo]

@niZmO_Man okay sweet as cheers bro I’ll look for turbo an then go from there 

[GTSBoy]

Turbo + fuel system + ECU + intercooler + pipework + exhaust manifold + oil&water plumbing to/from turbo + exhaust + dump pipe + installation work for oil supply and drain, etc. + tuning.

The list really should include upgraded brakes.

Oh, and you're in Victoria. So what you are proposing is not road legal. You will need to pay for engineering.

[JohnnyR31Silo]

@GTSBoy I would want it to be street legal 

I’m trying to make it full on just basic turbo an psi and what not.. even if you can recommend a garret turbo would be much appreciated.. I know there’s different sizes an what not so if you can recommend one that’ll fit good an wont go to hard to not be street legal 

[JohnnyR31Silo]

Iv been looking around found one on market place he reckons it came off a Jeep commander an reckons it’ll be good for a r31 but I’m not sure which is why I’m showing you guys
