More individual tests and a couple professional tests will and would be good, as it broadens the range of tests done i say, but will clearly watch this page closely

maybe they should like alot BIN Numbers to them like penfolds red wines :D how many bins it took to get the perfect one. But aggreed, its trial and error to which batch you get/got

Yep we can compare it exactly to wine :)

ok as you know i recived my plenum a while ago got around to doin some work to it i have pics of before and after i will post up soon

well the casting was pretty average on the inlet ports they were a fair bit smaller in some cases which i can live with cause i had all intesion of match porting it anyways

i die grinded eveything came up a treat also clease up the water holes

i also cleaned up the inlet the inside was all pretty good wat you would expect form any plenum pretty much the same as my standard one

i then preped the top half of the plenum and grinded away the part where the greddy is normaly stamped

i then have sprayed it with this spray on bog stuff which give it a nice smooth fininsh only problem was i only done the top half not the bottom so that started to flake off cause of the crap dodgy silver paint that its painted in so im suggesting that you should get it diped n cleaned before any painting is done

i dont see how it will brake as it is structual solid no weakness

i can see improvment in air flow by a big diffrence but tune will only tell

all this was done in the matter of say 12 hrs (and i dont work fast lol)

pics will be up as soon as i can get them up

Thanks from the update, keep us posted :)

Just a suggestion.

I would not use any bog type spray on the plenum, as the aluminium expands and contracts as it heats and cools, which may result in cracks appearing in the bog, or the bog flaking off.

My mate had his genuine GReddy plenum powder coated, b4 install, and within a month crack were seen. The powder coater i/we use does awesome work and no cracks/faults on any other engine parts. My standard plenum is also p/c'ed and cracks can also be seen.

yer have progressed alot in fact is it finished but my camera died i have painted it gloss black to keep it well sort of stelth iov moved away from the polished look ill try n get pics up asap

i will put up my dyno result as soon as i can to might get it flow tested will its off

i spose you can i dont know much about the 32's im guessing the ports would be smaller but being a stock standard car i would not bother my standard manifold supported up to 280rwkw try and find one already done for a rb20

HAHA i hope these are the ones hydro'ing engines as the water port was taped into the intake runner..... if nto all good, i prefer the finish of the genuine ones but hey who am i to judge if it works. :P

    • Brooooo Please send ABS control unit schematic Please! R33 gts25t ABS (Its two plug ecu, black and white) wire colors possible? [email protected]
    • Don't even try to run it on the stock ECU if you're going to have the boost controller bring boost above ~10 psi. I've already told you that. If you use the Nistune ECU, you will need to CAREFULLY read the available documentation for Neo tuning, and read some threads on the Nistune forums, to discover the various things you have to do to prevent the ECU from going bananas when the boost is too high. The is a table associated with th boost sensor that must be modified to prevent it from shitting the bed. This is just one of the things that you will need to do to the tune in Nistune, because the Neo turbo ECU will be expecting to see a number of things (such as the TCS) that are not there, and you have to block the DTCs on those. It is totally not surprising to me that you are having the problems that you are, but the solutions to these problems have been known for >15 years. So just get it done.
    • Hi. Sry iam not a mechanic and iam not at the car atm so i dont know 100% but they told they measure those and even try to change those. AFM they have two. Coils are new a they have my old one too. Plugs too. ECU...we have 25 NEO stock and Nistune 25 NEO.   But i dont know if any one those could be the problem and why/if/what can cause this, Only thing they did not check is fuel...but that walbro 255 is new(like 1,5 years)... That fuel pressure gauge idk...but i let them know Any suggestions?   EDIT: how can they know if it is like you say he ECU pull power when it reaches a specific boost level that is too high? Tha car has boost controler
    • Can you clarify what you mean by boost cut, do you mean it misfires both when under load (driving) and when stationary and out of gear? Or does the ECU pull power when it reaches a specific boost level that is too high (boost control issue)? Does it occur at idle with no throttle? When you say "the ECU is OK", what ECU is it and why do you think it is OK? Have you used the NEO ECU, and if so do you have a MAP sensor attached? Same for the AFM, why do you think it is OK? Do you have any way to put a fuel pressure gauge on it (even just a mechanical one between the fuel filter and fuel rail)?
