My Skyline is a R32 GTS-T

Hi Everyone, 2 questions.

1. I was wondering what are the benefits of getting a better plenum and is it worth the money?

2. My car seems to be unstable when driving like a boat and it feels uneasy taking corners like it is going to slides out very easily on tight bends even when taking them at slow speeds. Do I need to get coilovers and dampen it? Also my steering wheel shakes over 100km per hour?

Any feedback is much appreciated.

Shakes over 100kph for me have often been a slightly warped rim usually on the front. Not always but often. Try align and balance first, much cheaper than new rims.

A new plenum isn't worth the money if you are chasing power mods. I have a front-facing plenum but I don't pretend that I get more power out of it. I did primarily to get better throttle response because of shorter intercooler piping which I think it does pretty well. But other bonuses are the plugs/coils and injectors are MUCH easier to get to, and the engine bay looks neater (nice sort of custom look). I also saved on 2 mandrel bends and 3 straight bits of cooler piping (got FMIC installed at the same time), so that subsidised the cost of the plenum.

I wouldn't pay more than $500 for a plenum if you wanted it for similar reasons to mine above. If you just wanted more power I wouldn't pay more than $0! I remember ages ago there was someone from New Zealand selling his own brand for around $350 I think, but try as I might I can't find his site or any threads about it. If someone knows who I'm talking about please let me know! His plenum looked heaps better than mine and looked like it flowed more evenly, and I'd be happy to pay $350 for the bling bling :yes:

my car used to shake at over 100ks as well

was a combination of bad suspension and its effects on the tyres

fixed the tyres, came back after a bit

fixed the suspension and all good

i too have a forward facing plenum, just seemed like a smarter idea than running piping all through the engine bay with extra bends

certainly makes for easier access to engine

The std R32 plenum has been proven to be fine for 300rwkw. :yes:

I didn't have issues with running pipeing through the engine bay as I run an fmic that has the in/out positioned towards the center of the core.

I use the stock ic piping route then have the hot pipe out of the turbo running behind and slightly lower than the core, it throws a 180degree turn in to the fmic, the cool pipe has a nice short route out of the fmic that uses the stock piping route. One added bonus is I can't be defected on for cutting holes for the fmic piping. ;)

I think you might be talking about rips he makes his own plenum also specializes in the rb30 too i think .

I think you are 100% correct! And yeah I forgot to mention that a lot of VL Commodore guys had them as well. Thanks for that, another thing to add onto the list of things to get :( (hope he's still selling them when I have enough money)
