Guys sorry to reply so late, I see there have been a few comments re this plenum. As far as my boost goes, the issue only occurred after going from the previous turbo's to the 2530 Kai's and installi

Steve-SST: Yeah, I know its not a massively sensible purchase, but my aim is response first, second and third, plus I can source one for Y130,000.

But I don't want to be the first guinea pig :rofl:

LW.

Yes you do... Its for the good of the group! ;)

bumping any old topic,

Has anyone used one yet? im debating if it is worth it, not so worry about the cost. Just want to know if it does have any gains over a std plenum.

The car its going on is a track car with the goal of responds if that makes a difference.

My plenum is coming off to install my map sensors, so was thinking it would be a good time to swap over

Does that mean we should all go out and buy one Trent? ;)

Along with tricky prop shafts, possibly different diff gears and so on? :(

Factory is fine - Racepace have tested it, factory was better for what you want over a Greddy/Nismo.

If they were good, then cars wouldn't have had them taken off for a stock one to go back on :D

Same as all your other fancy bits mate - 95% of them are not going to offer you any benefits @ the track - learning to drive your new car over a season or two will give you far better improvment and the best part...

It's free :(

I agree with Nismoid I would spend more time thinking about your modifications and want you want to achieve and less on brand... save you heaps really.

That being said; if they were no good, the GT cars would be removing them! Factory is fine; Nismo is better... worth it for over $2k? No!

Oh i agree - im sure there is some alteration - somewhere.

But they are all out racecars where some things are not important (like low end response, coupled with different gearing, motor properties etc, all subjective)

interesting because nismo state it helps low end response (increase response throughout the rev range)

if price is right looks like i pick it up

Well a product maker isn't going to tell you their product doesnt do anything are they now?

IMO your buying simply because it has a jap label is silly, and pointless.

Especially for a circuit car where they are far more crucial things - but we've all said it 10 times now in th MSport area :(

I understand what your saying, i have been doing alot of reading lately regarding what to upgrade and what not to upgrade. i don't want to go silly with the engine... i know if i open that door i will end up doing broke, and never getting the car racing.

If the nismo plenum was full price there is no way i buy it but when there is a chance i can get it alot cheaper for a near new one why not :(

for me its price v's gain. i try and find bargins. 2k for nismo plenum, wouldn't buy. 1k for nismo plenum now we are talking :(

In the red corner weighing in at mega we have Nismo. They have obviously dropped a fair amount of coin in to the research, development and production of this product and, given their track record i see no reason to doubt their claims.

In the blue corner We Have Nismoid. He hasnt spent a plug nickel on testing the validity of the makers claim as to the performance benefits of the product. Matter of fact I doubt he has even seen one.

Now who do I believe. HMMMMMM! :(:D

out of interested, when racepace tested it, why wasn't it better?

the information out there about the nismo plenum is limited all i can find is what nismo has posted

img_clctr_graph1_en.gif

img_clctr_graph2_en.gif

Specifications

* Collector volume: 4.1 liter (genuine = 3.4 liter)

* Intake pipe length: 73.8mm (genuine = 48.5mm)

* Intake pipe diameter: tapered from 43 to 45 (genuine = 45)

* Material, production method: cast aluminum

* Intake temperature difference at the entrance of turbo chargers is improved averaging18% in 2,400 to 7,600 rpm range.

* At 4,800 to 7,600 rpm, power output is increased by an average of 1.8%, while fuel economy is improved averaging 0.4%

also interesting to note nismo say:

This product cannot be installed with the engine mounted

having look at the plenum i would have through it could be done with the engine in the car?

me, well i would not spend that money but after speaking to a few jap tuners in japan they all swear by them (better overall distribution and good gains even on small setups)... just one shop here does not like them.. hardly enough to convince me they "aint all that"

Basicly i agree though for 2k id spend it elsewhere to gain a few 10ths... but if you have the coin spare do it.

1.8% - Yep, certainly more critical things to spend the money on as i said in the first post :(

Which is really the point at the end of the day. Nice to have... However pointless when there are 100 other points that need addressing for this users aim in a midly powered circuit car.

Removing the sound deadening would be significantly more beneficial and you can do that for around $100.

      R32 update from 1990's spec.

      New CAS just turned up from NZ Wiring. Looks like a nice bit of gear.  So, yeah. Triggered, bro. Realised I may as well do the cam belt while mucking about with it so will order one of them.

      Even more fun, leave all the ADAS stuff plugged in, but in different locations, hopefully avoid any codes!   And honestly, all these new cars with their weird electronics. Pull all the electronics out Duncan, and just shove an aftermarket ECU and if needed a trans controller in, along with a PDM. Make it run basic but race car styled!

      To follow up a question from earlier too since I had the front bar off again (fking!) This is what is between the bumper and the drivers side wheel And this is the navigator side, only one thing but its a biggy! So basically....no putting coolers in the wheel arches without a lot of moving other stuff. Assuming I move to properly race prepping this car I'll take that job on and see how the computers respond to removing a whole bunch of ADAS modules

      Duncan's V37.......race car?

      By Duncan · Posted

      So I prepped the car for another track day on Wednesday (will be interesting to see coolant temps post flushing out and the larger reservoir, with a forecast of 3-14 being 20o cooler than last time I took it out). Couple of things to mention; since I am just driving the car and not taking a support vehicle, I took the rear seats out and just loaded the back up Team Trackday style. Look at all that space! To cover off removing the rear seat....it is weird (note the hybrid is probably different because it wouldn't have folding rear seats) Basically, you remove the lower seat base, very similar to a r series but it is a clip that pulls forward to release the base rather than it being bolted down. Easy Then, you need to remove the side section of the rear seat on each side. There is a 14mm head nut at the bottom of the side piece, the it slides upwards off a hook at the top to release; you also need to unhook the seatbelt from the loop at the top. Then the centre piece is weird. You need to release/fold the seats forward with the tab in the boot on each side From there, there are 2,x12mm headed bolts holding the rear of each seat to the folding bracket, under the trim between the rear seat and the boot (4x christmas tree clips there, they suck). The seat is out but you can see where the bolts attach to the bracket

      As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year.
