I had about a 50hp increase from just putting a RB25neo turbo and a fmic on my stock RB20..

For my RB25 i am getting a KKR480.. have a look here the KKR430 would work a treat on an RB20!

^^^1 bar will NOT get you there. nor will any other boost pressure. couple of mates have has this turbo on rb20s and the most either got was 205, other was 185. both after tuning. driven the one with 185, response is about the same as that of a turbo capable of 240rwkw... you'd think a 0.58 turbine A/R could achieve so much more...

orginal question:

ryan (1400R) is right, the td06-20g that he's selling (quite cheap too) will get you there. it also has the smallest exhaust housing and is quite a good match for the rb20.

another option is the gt2871r from garrett, but with the stock rb20/rb25 exhaust housing put on it so that it bolts up. horsepower in a box offers this.

these are the 2 options that i'm tossing up between (or was till i realised i dont have the money for support mods). both make similar power and similar response, with the garrett maybe a little bit better as its ballbearing

"or was till i realised i dont have the money for support mods"

what supporting mods you only need a fcd and a fuel pump

most should already have a larger fuel pump fitted so you only need a fcd $250 easy

remap it later when you've got some more cash together

Maybe...but there are plenty of RB20s blowing up.

But the ones with SAFCs, FCDs and off the net re-maps seem to blow up mire only makign 180-200rwkws. There are a few RB20s with 2530s making 210-220rwkws with Pfc, there are some RB20s running bigger Garrets etc making over 230rwkws reliably with management. Its not a perfect rule but i think its more then just a coincidence?

Just my thoughts, but why spend the money on a new turbo if you can afford to get the ECU to run it. Its only goign to give asmall increase in performance and cost you more in the long run.

Im all for doign things on a budget, but tune maketh the car.

FCD, that doesnt even change the ignition or the fueling does it> Doesnt it just stop the std ECU doign the fuel cut dance when it senses too much airflow?

yeah, i'd rather wait till i have all the money to do it properly, just in case.

want injectors, new pump (dunno if i want to trust a 16yr old gtr pump), and would want it tuned straight away

FCD as far as i know changes what the ecu 'sees', similar to SAFC

for rb20 may aswell just get the stock ecu remapped and tuned, does the job well

Remaps ftw... hehe

All i can say is less lag is important on a standard rb20! It won't run like an rb25 off-boost, or even an sr20 for that matter lol

14psi wont do much on an rb20 either, you really need 17++ psi plus alot of rpms to start to make any real decent power on MOST turbo's

The TD06 seems like a pretty good choice, i have the gcg hi-flow (from a r33 turbo) and its abit laggy really...

When it gets going its great like on the freeway etc, but waitin for it to spool up can be frustrating esp in low gears, 1st gear is nothing nothing then all hell breaks loose for half a second LOL

      My guesstimate, with no real numbers to back it up, is it won't effect it greatly at all.its not a huge change in position, and I can't see the air flow changing from in turbulence that much based on distance, and what's in front of it. Johnny and Brad may have some more numbers to share from experience though.

      Which solenoid? Why was it changed? Again, why was this done? ...well, these wear..but ultimately, why was it changed? Did you reset the idle voltage level after fitment? I'm just a tad confused ~ the flash code doesn't allude to these items being faulty, so in my mind the only reason to change these things, would be some drive-ability issue....and if that's the case, what was the problem? Those questions aside, check if the dropping resistor is OK ...should be 11~14 ohms (TCU doesn't throw a flash code for this) ~ also, these TCU designs have full time power (to keep fault code RAM alive), and I think that'll throw a logic code (as opposed to the 10 hardware codes), if that power is missing (or the ram has gone bad in the TCU, which you can check..but that's another story here perhaps).

      Question for people who "know stuff" I am looking at doing the new intake like the one in the picture (the pictured is designed for the OEM TB and intake plenum), this design has the filter behind the front bar, but, the filter sits where the OEM duct heads into the front bar, and the standard aperture when the OEM ducting is removed allows the filter to pulled back out of the front bar into the engine bay for servicing, a simple blanking plate is used to seal the aperture behind the filter This will require a 45° silicone hose from the TB, like the alloy pipe that is currently there, to another 45° silicone hose to get a straight run to the aperture in the front bar Question: how will it effect the tune if I move the MAF about 100-150mm forward, the red is around where my MAF is currently, and the green would be where it would end up Like this This is the hole the filter goes through  Ends up like this LOL..Cheers

      Despite the level up question, actually I do know what that is....it is a pressure sender wire.  So check out around the oil filter for an oil pressure sender, or maybe fuel pressure near the filter or on the engine. Possibly but less likely coolant pressure sensor because they tend to be combined temp/pressure senders if you have one. Could also be brake pressure (in a brake line somewhere pre ABS) but maybe I'm the only one that has that on a skyline.
