honestley its perfect for a RB25 but i would not put one on a std rb20... well actually i would if it was mine... but it will be quite laggy and they really require 1.2-1.3bar to make it into thier sweet zone.. if you were a customer i would say sell the t67 and fit the l2 to the kit you have, if it was me i would slap it on and start playing on the dyno

where are you located? i tune heaps of wolf's and would be happy to slap it on the dyno just to assure you one way or the other....... im in dandy vic. Bring me Nando's or a 6 pack of JB and we will call it even

i've been trying to get a dealership as i have a few customers wanting them but melbourne is tied up with JPC and so far i have not recieved more information.... still waiting.

haha its on!

yeah agreed, i was speaking to *&^% the D1gp and SUPER LAP blitz mechanic who is a JUN freak (for engine internals) and they tried all inlet manifold combinations on nomukens R34 which is a 580ps nismo 2.8l kitted rb25 with NEO head and GTR individual throttle bodies and it was the nismo inlet plenum that came up trumps. I would seriously consider the nismo item. He was the legend who built my exhaust manifold for me.

yes on some cars, esecially twins the table flat boost control is due to the fact it has double the resolution compared to a single solenoid. (mind you if the gate setup is good a single solenoid will easily suffice) the DSBC just allows more scope to adjust an unruly gate a nd still maintain a nice flat curve. (there are cases though that no controller can fix a boost drop or creep if it is of mechanical origin... too small a gate etc..) the extra response is more a product of software programming and i can only assume is the fact that opening two valves at once allows you to hold out to the last possible moemnt yet still pass the required volume through to the gate/gates without spiking. i dont want to get into a blitz is best type argument as the whole point of my post was merely to prove that a properly setup EBC can gain you quite a LOT of extra FREE power

no it only has a duty cycle setting.... as for being an sr20 all pfc boost controllers are the same see attched SR20 screen grab.

honestley the blitz boost controller really comes into its own in twin applications, im sure there are a few guys on here with crazy GTR's who will back me up (dirt garage for one).

The only differerence is the way the cursor traces through the maps, tuning is the same, RB20 and RB25 is no issue..... vg30 is also no drama i really prefer to get my fueling tables spot on instead of using the arflow % adjusters but on some problem cars it can be handly for hunting idles etc... all things you need not worry about with the d-jetro yes it still has o2 feedback (closed loop) but honestley you can tune them up good enough not to have to use it. i usually only do it as a drive in drive out operation but i can modify the the internal plug to suit either rb20 or rb25. Pm me for pricing. yeah i dont use the hand controllers anyway, fc datalogit ftw they are all separate but i can supply the whole lot.

yeah new i sell them for $4900. ABU... buy ROYS, honestley this R31 with the L2 is the BEST rb20 i have ever driven........ and one of the most fun cars ive driven full stop.

to be fair gary you are quite perceptive but for the sake of 95% of the readers i prefer to keep things simple and more akin to what many of the readers will experience in real world situations. firstly we need to ignore the manual MBC graph because it was actually from the int gate garret setup on the car previously and is one of the reasons i did not go into listing direct comparisions, i should have made note but i figured people would ignore it as there were no power figure to compare it to.. secondly the wastegate has a .9bar spring in it as the customer wanted to run a low boost setting of 0.9 and a high boost setting of 1.25bar... as it is a stock engine after all. Of course in a perfect world we could have run a heavier spring to bring it as close to 1.2bar as possible but we had the issue of a low boost setting of 0.9bar... the best compromise was to adjust the preload on the trust gate to get the best boost ramp as possible without spiking at 0.9bar. so yes the BLUE and GREEN graph shows the maximum possible boost curve for this setup, without resorting to locking the wastegate shut

100% this car is used ALOT (daily) and spends alot of time doing hills runs and we have been developing the car for response so he knows it inside and out, im pretty sure it just pulled 1.45 around winton which is not too bad considering it was his his first time at winton on street tyres. The car has actually has had two turbo setups on it previously gt30 int gate and a gt35r both were not up to scratch (too laggy).

Any Blitz dual solenoid in my experience works the best (gain wise), i have plenty of graphs i could post up but i rate the boost controllers as follows; 1. BLITZ dual solenoid (type R, ID, IDIII or I-color) But i find the i-color is a bit too gadgety. 2. Gizzmo MSIBC (black with blue display) (awesome controller with closed loop boost control and cheap) 3. TRUST Profec b SPEC 2 (great controller, easy to set up)

yeah i had the 180sx folder open when i printed the skyline graphs.... my fault Car is a R33 with unopened rb25 and a custom 8cm T67 kit i ordered from trust for it. Final result was 310.1rwkw @7200 and 427.9Nm at 6100rpm (makes 392 @ 4100 though so its got quite a broad torque curve.)

i have in the past been flamed for posting that the PFC boost controllers are fairly average so when the opportunity arose to do a back to back test i could not resist. I have the done the comparison below on power as it seems people take more note of power than torque... i dont know why. For those who want the real story i have included the torque graphs as well. Over the years i have seen excellent gains with a good ebc i have even seen midrange gains in the vicinity of 50rwkw, i know this is a lot and to be honest it was on a car making well over 300rwkw. The example below is what i consider an average skyline setup and it gained between 10rwkw and 32rwkw between 3000rpm and 4300rpm...right in the area you need it most.... more importantly torque at 4000rpm rose by 80nm just by using a boost controller with GAIN control. Below are two graphs one is power and torque graph the other is a boost graph; Thin red line is a manual boost controller set to 1.3bar (i have not included power runs as it is obvious it would be way lower) Thick red line is PowerFC boost controller, holds good boost all the way to red line and makes the following power; 62rwkw @ 3000rpm 80rwkw @ 3500rpm 120rwkw @ 4000rpm 180rwkw @ 4500rpm 200rwkw @ 5000rpm 240rwkw @ 6000rpm 269rwkw @7000rpm Thick green line is Blitz IDIII boost controller with correctley set gain, holds good boost all the way to redline and makes the following power; 74rwkw @ 3000rpm (12rwkw gain) 90rwkw @ 3500rpm (10rwkw gain) 152rwkw @ 4000rpm (32rwkw gain) 180rwkw @ 4500rpm 200rwkw @ 5000rpm 240rwkw @ 6000rpm 275rwkw @7000rpm Thick Blue line is Blitz IDIII boost controller set at 1.25 so it cant be compared directley but it shows just how much extra power and torque can be gained with the CORRECT GAIN setting in your boost controller. If this 1.25bar was runj with the PFC boost controller it would have made the same peak power but would have followed the red line... thus missing all the extra midrange torque and power; 74rwkw @ 3000rpm 90rwkw @ 3500rpm 152rwkw @ 4000rpm 190rwkw @ 4500rpm 218rwkw @ 5000rpm 250rwkw @ 6000rpm 293rwkw @7000rpm

to true ^^^

this engine has never been opened it is a wrecker special.

send me the 26 ecu and i will set it up so it plugs in and fires up straight away.

if you get stuck send the unit to me: Status Tuning 63 rodeo drive south dandenong 3164 att Trent Hewitson i will get the patch loom and load it up with a decent RB20 base image for you.

hahaha i tune heaps of wolfs and yes the V500 is real nice unit but at the end of the day 99% of the ones that come in to me run like shit and i spend more time retuning other peoples f**k ups...... if your in vic im more than happy to have a look for you. For all RB20's now i use r32 gtr PFC's... much nicer results.

sounds like cock and bull to me.

done will post later today, obviously peak power was the same as was response, torque etc. Bear in mind it was a modded car... i saw no pont testing a near stock car back to back.

Adriano, i bit the bullet when setting up the shop and decided to use the best dyno money can buy, after spending ALOT of time using all brands whilst contract tuning and talking to many operators here and overseas i finally decided on the dynapack, the benefit of spending so much more on a dyno over say a dyno dynamics is quite simple.... accuracy. i am able i to log and show every little bump and variation within a given run something that NO other dyno can do. To the inexperienced the dynapack torque and power curves look kinda ragged but that is just because it does not have the large rollers to dampen the curve. The torque curve above foir the RB20 is almost perfect, most cars tend to have more variance than this one. (i will post a stock RB25 graph for a comparison as STD R33 tend to have the worst powerr delevery) The small fluctautions in the dynapack torque curves are masked by other types of dyno's because they use large rollers wihch have a lot of inertia.... (think big flywheel) the intertia contained within those rollers on other dynos flatten out any dicrepencies. If this was to go on a dyno dynamics (or any inertia type dyno) it would look text book perfect but that is useless to anyone who is actaully trying to maximise torque /HP lastly boost on this car was table flat. (see graph)

It is an expensive air filter adaptor hahaha i was still waiting on the Z32 airfliter adapter turning up.
