ah sweet mite have to pop in there and grab some. yeah the cars coming along just about ready for a tune in the next few weeks. just a few little things that i gota clean up

Cool, sound like you guys are doing well.

Question, you guys seem to know about cams. I have some HKS cams that I got and was wondering what kind of response they might have in my car. The cams are 272 measurements. I have a stock R32 GTS-T with cat back exhaust 3 or 4 inch I believe.

i reckon +3 IN -6 EX is about right given thats pretty much what Roy's using.

Was it, i mean is it? Since we had the head to head i had the thing tuned again with and without the cams. Working on the tune with the std cams yielded better results. So i have no idea what they are set at presently. If thats what they were set at (possibily still there) then it wouldnt hurt as a starting point

LOL..i dont thin many if us really know exactly about the cams as not many people do the cams in insolation, with a good tuner before and the same tuner installing and tuning the car post cams for a true test.

That all said, unless you have a serious RB20 the cams you have are figgin huge for a 2L six

So they are too big? I was planning on putting in a RB25 turbo, maybe a trust FMIC(nothing too big, don't want alot of lag), fuel pump and 550cc injectors, split front pipe, sports cat, boost controller, and a Emanage for the ECU and get tuned. I might put the FMIC last, not sure if want a bigger FMIC.

Thats what they were set to when Sam looked at it - pretty sure..

went to start the old girl last night to prime the system with oil an wat not. and all the frickin headlight wiring decided it'd let all its smoke out from underneath the plastic. dunno wat the cause of it was still tryin to find out why. yet another set back :(

Thats running a big exgaust housing! May make the setup a little laggier then ideal

Thats running a big exgaust housing! May make the setup a little laggier then ideal

same as my old car used to have roy... seems huge but works well

also tread bump because soon ill be back in the rb20 game, thinking along the lines of 125hp shot of nos on a standard rb20 with 25 turbo :)

rb20 4 lyfe

quick question

who is making over 260rwkw still running standard cams, springs and plenum?

please list forum names (for contact) and mods if you know

Ive had a look through this thread and also the rb20 turbo upgrade thread already

not sure if people are leaving off plenum mods or if they havent got any

basically Im after soild over 260 figs to count out high reading dyno's seems alot of guys are hitting the 250-260 not may going over that though

the only one I know of is the one my work bought in full drap setup stroker with 26 plenum mod'd for q45 tb t78 full step 3 head job

or if you prefer whats the limit of standard 20 head and plenum?

Edited by 1400r

Another question, Im loking for a forward facing plenum for my RB20, are there any off the shelf ones available? Or Will I have to go a custom job?

Would also be interested in knowing what effect it will have....

(BTW Ryan, Ill be in tomorrow arvo to put some cash on that TD06....)

Huddy'e emo lets see if we can get to the bottom of the problem

i am running std inelt manifold, std cans, std springs, std throttle body and std GTR injectors in the std rail with std fuel reg. If i put an aftermarket fuel reg on it i will be able to wind a bit more out of the gTR injectors. I have only dyno'd my car with 19psi but i have run it at as high as 22psi but shouldnt because i am maxing out the GTR injectors. That and my means of boost control isnt great fdor trying to get that much boost into it from an 8psi spring.

I also made 245rwkws or something on a Mainline dyno that always read lower then Dyno Dynamics by 20rwkws odd.I think i was running abotu the same boost as the above graph. Juts need more injectors to squeeze a few more kws out of it, but thats only for the sake of chasing a number. Which i dont care about, as long as the car is fast and reliable at the track

here you go,

http://www.nismo.com.au/pricelists/priceli...ylineengine.htm

scroll down and search for "UAS PLAZMAMAN RB20DET CUSTOM PLENUM"

Thats a very nice plenum. Kinda pricey though

(I know you cant get "good" and "cheap" in the same sentence, but Im not super keen on spending that much if it's gonna make 5 5ths of f**k all difference)

I can get this one made for $350 cheaper (all internal bellmouthed/smoothed/match ported etc.) or have it installed and cooler piping get all my cooler piping modded for roughly the same price as the UAS kit.

Although Id still have to get new cooler piping made, so Id be realistically looking at a $1500 - $1800 proposition by the time im done, and might not gain very much at all from that? Be better off buying some cams and more tuning I reckon.

I still wouldnt mind doing it simply to remove the 3.5 foot of piping off the top of the motor, and neaten it all up I guess.....

Go to www.ripsltd.co.nz

He does rb20det plenums for about 1000aud, you wont find much better, the quality and fit is perfect! I had one on my old r32 gtst, i can try and post some pics if you need them?

I can get the one I posted for about $1100 - $1200 fully Installed..... modded piping and everything. I know we're talking about a couple of hundred dollars here, but to me thats a shitload easier. Drop it off and pick it up done.

Reckon there's probably more/better/cheaper gains to be made in cams and tuning.

Anyone else care to comment on this?

    • Yea that’s why I said ima test them with multimeter and see the reads.
    • Only at idle. Isn’t a problem when rev it seems.
    • @Haggerty This seems silly to ask, but are you confident in your ability to tune the Haltech?  
    • Next on the to-do list was an oil and filter change. Nothing exciting to add here except the oil filter is in a really stupid place (facing the engine mount/subframe/steering rack). GReddy do a relocation kit which puts it towards the gearbox, I would have preferred towards the front but there's obviously a lot more stuff there. Something I'll have to look at for the next service perhaps. First time using Valvoline oil, although I can't see it being any different to most other brands Nice... The oil filter location... At least the subframe wont rust any time soon I picked up a genuine fuel filter, this is part of the fuel pump assembly inside the fuel tank. Access can be found underneath the rear seat, you'll see this triangular cover Remove the 3x plastic 10mm nuts and lift the cover up, pushing the rubber grommet through The yellow fuel line clips push out in opposite directions, remove these completely. The two moulded fuel lines can now pull upwards to disconnect, along with the wire electrical plug. There's 8x 8mm bolts that secure the black retaining ring. The fuel pump assembly is now ready to lift out. Be mindful of the fuel hose on the side, the hose clamp on mine was catching the hose preventing it from lifting up The fuel pump/filter has an upper and lower section held on by 4 pressure clips. These did take a little bit of force, it sounded like the plastic tabs were going to break but they didn't (don't worry!) The lower section helps mount the fuel pump, there's a circular rubber gasket/grommet/seal thing on the bottom where the sock is. Undo the hose clip on the short fuel hose on the side to disconnect it from the 3 way distribution pipe to be able to lift the upper half away. Don't forget to unplug the fuel pump too! There's a few rubber O rings that will need transferring to the new filter housing, I show these in the video at the bottom of this write up. Reassembly is the reverse Here's a photo of the new filter installed, you'll be able to see where the tabs are more clearing against the yellow OEM plastic Once the assembly is re-installed, I turned the engine over a few times to help build up fuel pressure. I did panic when the car stopped turning over but I could hear the fuel pump making a noise. It eventually started and has been fine since. Found my 'lucky' coin underneath the rear seat too The Youtube video can be seen here: https://www.youtube.com/watch?v=uLJ65pmQt44&t=6s
    • It was picked up on the MOT/Inspection that the offside front wheel bearing had excessive play along with the ball joint. It made sense to do both sides so I sourced a pair of spare IS200 hubs to do the swap. Unfortunately I don't have any photos of the strip down but here's a quick run down. On the back of the hub is a large circular dust cover, using a flat head screw driver and a mallet I prised it off. Underneath will reveal a 32mm hub nut (impact gun recommended). With the hub nut removed the ABS ring can be removed (I ended up using a magnetic pick up tool to help). Next up is to remove the stub axle, this was a little trickier due to limited tools. I tried a 3 leg puller but the gap between the hub and stub axle wasn't enough for the legs to get in and under. Next option was a lump hammer and someone pulling the stub axle at the same time. After a few heavy hits it released. The lower bearing race had seized itself onto the stub axle, which was fine because I was replacing them anyway. With the upper bearing race removed and the grease cleaned off they looked like this The left one looked pristine inside but gave us the most trouble. The right one had some surface rust but came apart in a single hit, figure that out?! I got a local garage to press the new wheel bearings in, reassemble was the opposite and didn't take long at all. Removing the hub itself was simple. Starting with removing the brake caliper, 2x 14mm bolts for the caliper slider and 2x 19mm? for the carrier > hub bolts. I used a cable tie to secure the caliper to the upper arm so it was out of the way, there's a 10mm bolt securing the ABS sensor on. With the brake disc removed from the hub next are the three castle nuts for the upper and lower ball joints and track rod end. Two of these had their own R clip and one split pin. A few hits with the hammer and they're released (I left the castle nuts on by a couple of turns), the track rod ends gave me the most grief and I may have nipped the boots (oops). Fitting is the reversal and is very quick and easy to do. The lower ball joints are held onto the hub by 2x 17mm bolts. The castle nut did increase in socket size to 22mm from memory (this may vary from supplier) The two front tyres weren't in great condition, so I had those replaced with some budget tyres for the time being. I'll be replacing the wheels and tyres in the future, this was to get me on the road without the worry of the police hassling me.
