Hey guys,

I would take this to nissansilvia.com but we all know they are a bit weird over there lol. Anyways, I have a mate with a SR20DET S13, his not planing any huge modifications, but we would still like your opion.

Air Intake - Apexi or K&N?

Exhaust - Either a Apexi N1, or something HKS

Spark Plugs - Splitfire with there twin sparkers or the Top NGK ones?

Intercooler - I don’t have the ??x??x?? but it’s either a HKS or Greddy, HKS's one seems to be a lot Higher, but Greedy’s seems to be a lot Longer.

What would you guys go for?

I had one of those exact cars before my GTR. I hope its a Manual :P

Air Intake - K&N is fine

Exhaust - 3" straight through turbo to tip. (with 3" dump pipe).. brand name mufflers are simply over rated. Use the money you save on not buying a jap muffler towards a decent IC installation. I had a generic but good quality stainless steel generic 3" muffler and my car sounded bloody awesome and gave enormous power.

Spark Plugs - The most expensive copper plugs work just as well if not better than ngk's.. Bosch twin sparkers are good too.

Intercooler: Once again, buy a good quality generic intercooler and piping and spend the money on a top quality installation job.

With those mods that car will be dipping into the 13s quite easily.

To me its all about bang for you buck. If you did that same setup with brand name japanese gear you'd be paying almost twice as much, and probably only getting a 27% power gain as opposed to a 24% power gain. (for eg.)

The difference is not worth spending almost twice the cash. Spend the money you save on an Apexi AVC-R boost controller or something like that :(

i have found 180sx sr20 with no mods was able to keep up with my lightly mod r33 untill 2nd (mid/end of the gear) so saying that with those mods i think a low 13 will be chance easy.

i would go

S15 turbo (BB and steel wheel cheap upgrade)

FMIC : Hybird 300x600x76 cost around $400 and another $500 for piping

Exhuast: Jap style cat-back with custuom dump and front pipe

Air Filter: any will do i have found K@N or apexi 2 be the best

plugs: dont replace untill u need too (i found that there was no point but jsut replace with good plantium plugs)

then maybe a safc II and ebc

for light mod and most bang for yr buck

air filter: K&N air filter in stock box

Exhaust : personal i don't care much about brand, but has to be turbo back (split dump, high flow cat) X force is good and cheap

Intercooler - S15 stock cooler will be good for 180rwkw

Turbo smart dual stage boost controller

(or EBC if u got the $, i love blitz as the hold the boost nicely, hell lot better than the Greddy e-01 i used to have)

Spark Plugs - won't do much, but i use top of the range NGK

maybe some computer? SAFC, E-manage, uni chip even power Fc?

get a RB AFM as well once u got yr computer

after that, u will need fuel pump, then mabe a S15 turbo + injector

s15 turbo is actually a much better turbo than the s13, particularly if you get a JDM one, not to mention atleast 7 years newer.

k&n filter, 3 inch generic exhaust, generic front mount, x force manifold, s15 turbo, 264 cams and a bleed valve.

On 11-12 psi you will see better than 180rwkw on stock ecu and injectors. And yes i've seen it done twice on 2 different cars with similar results.

Ecu, injector and afm upgrade will have better than 200rwkw.

Ok guys. ALOT of Shit has happened in the last 2 days. Firstly he got done by the cops again, so we took the damn turbo off for now. He isn’t happy.

Apart from your suggestions, my mate is a brands boy so he still went and got his,

NGK Iridium IX Spark Plugs

Apexi Air Filter

Splitfire Ignition Leds

3" Cat Black Apexi N1 Exhaust system

What do you think his non turbo ***** will make on the dyno now.

Thats pretty bloody retarded mate. No personal attack, but you did ask my opinion.

Whats the point of buying mods if you've 'removed' the turbo?

What the hell is the point?

Its like having sex with a condom

Its like skydiving without a parachute

:P

.. And why did you ask our opinion if you where just going to go and do all of the above anyway?

I think your a little lost, it’s my mates car, and I was asking on behalf of him, so don’t be hating on me.

The parts were ordered before the cops got to him, so we don’t like physically have them yet.

im with steve on this one the s14a j spec and s15 turbos are a great improvement over the normal t25g because of better power and also they are bb, im installing one on a stainless manifold with a split dump etc onto my new sil80 im building and all i want is 180rwkw and it seems i might just scrape it in :P

i found by putting a s14a jap turbo on an s13 sr20det it felt so much stronger and responsive compared to a r32 gtst rb20det with a 2530. both had exhaust/filter/fuel pump

both on ~14psi, then again 2530 isnt in its efficiency zone till 1.1-1.2 bar.

dont have dyno graphs to compare tho.

i'm no mechanic, just my 2 cents

actually mate the car would run, if he set it properly

but they cant defect the car for having a turbo charged engine unless it is a 'q' and unlicensed with that motor, even then the engine numbers wouldnt match making it illegal

err

what the fck is this convo about again!

Quick question - I've got a sr20 making about 200rwkw and I haven't upgraded my coil packs (or changed my spark plugs for that matter oops).

R33's friend has bought splitfire ignition leads (no coil pack?) without any of the mods I've got (fuel pump, fmic, injectors, re-chip etc).

What exactly is the benefit in doing this? Or is it a case of R33's friend having heard splitfire coil packs are good, then not being able to afford them buying the ignition leads instead?

No offence to anyone I just don't understand.

What would be the advantage of upgrading your coil packs and when would you do this? (is there a power level or symptoms where you can tell your coil packs are holding your reliablity/power/tune down?)

Thanks.

    • From there, it is really just test and assemble. Plug the adapter cables from the unit into the back of the screen, then the other side to the car harness. Don't forget all the other plugs too! Run the cables behind the unit and screw it back into place (4 screws) and you should now have 3 cables to run from the top screen to the android unit. I ran them along the DS of the other AV units in the gap between their backets and the console, and used some corrugated tubing on the sharp edges of the bracket so the wires were safe. Plug the centre console and lower screen in temporarily and turn the car to ACC, the AV should fire up as normal. Hold the back button for 3 sec and Android should appear on the top screen. You need to set the input to Aux for audio (more on that later). I put the unit under the AC duct in the centre console, with the wifi antenna on top of the AC duct near the shifter, the bluetooth antenna on the AC duct under the centre console The GPS unit on top of the DS to AC duct; they all seem to work OK there are are out of the way. Neat cable routing is a pain. For the drive recorder I mounted it near the rear view mirror and run the cable in the headlining, across the a pillar and then down the inside of the a pillar seal to the DS lower dash. From there it goes across and to one USB input for the unit. The second USB input is attached to the ECUtec OBD dongle and the 3rd goes to the USB bulkhead connected I added in the centre console. This is how the centre console looks "tidied" up Note I didn't install the provided speaker, didn't use the 2.5mm IPod in line or the piggyback loom for the Ipod or change any DIP switches; they seem to only be required if you need to use the Ipod input rather than the AUX input. That's it, install done, I'll follow up with a separate post on how the unit works, but in summary it retains all factory functions and inputs (so I still use my phone to the car for calls), reverse still works like factory etc.
    • Place the new daughterboard in the case and mount it using the 3 small black rivets provided, and reconnect the 3 factory ribbon cables to the new board Then, use the 3 piggyback cables from the daughterboard into the factory board on top (there are stand offs in the case to keep them apart. and remember to reconnect the antenna and rear cover fan wires. 1 screw to hold the motherboard in place. Before closing the case, make a hole in the sticker covering a hole in the case and run the cable for the android unit into the plug there. The video forgot this step, so did I, so will you probably. Then redo the 4 screws on back, 2 each top and bottom, 3 each side and put the 2 brackets back on.....all ready to go and not that tricky really.      
    • Onto the android unit. You need to remove the top screen because there is a daughterboard to put inside the case. Each side vent pops out from clips; start at the bottom and carefully remove upwards (use a trim remover tool to avoid breaking anything). Then the lower screen and controls come out, 4 screws, a couple of clips (including 3 flimsy ones at the top) and 3 plugs on the rear. Then the upper screen, 4 screws and a bunch of plugs and she is out. From there, remove the mounting brackets (2 screws each), 4 screws on the rear, 2 screws top and bottom and 3 screws holding in the small plates on each side. When you remove the back cover (tight fit), watch out for the power cable for the fan, I removed it so I could put the back aside. The mainboard is held in by 1 screw in the middle, 1 aerial at the top and 3 ribbon cables. If you've ever done any laptop stuff the ribbon cables are OK to work with, just pop up the retainer and they slide out. If you are not familiar just grab a 12 year old from an iphone factory, they will know how it works The case should now look like this:
    • Switching the console was tricky. First there were 6 screws to remove, and also the little adapter loom and its screws had to come out. Also don't forget to remove the 2 screws holding the central locking receiver. Then there are 4 clips on either side....these were very tight in this case and needed careful persuading with a long flat screw driver....some force required but not enough to break them...this was probably the fiddliest part of the whole job. In my case I needed both the wiring loom and the central locking receiver module to swap across to the new one. That was it for the console, so "assembly is the reverse of disassembly"
    • But first....while I was there, I also swapped across the centre console box for the other style where the AV inputs don't intrude into the (very limited !) space.  Part# was 96926-4GA0A, 284H3-4GA0B, 284H3-4GA0A. (I've already swapped the top 12v socket for a USB bulkhead in this pic, it fit the hole without modification:) Comparison of the 2: Basically to do the console you need to remove the DS and PS side console trim (they slide up and back, held in by clips only) Then remove the back half of the console top trim with the cupholders, pops up, all clips again but be careful at the front as it is pretty flimsy. Then slide the shifter boot down, remove the spring clip, loose it forever somewhere in the car the pull the shift knob off. Remove the tiny plastic piece on DS near "P" and use something thin and long (most screwdrivers won't fit) to push down the interlock and put the shifter down in D for space. There is one screw at the front, then the shifter surround and ashtray lift up. There are 3 or 4 plugs underneath and it is off. Next is the rear cover of the centre console; you need to open the console lid, pop off the trim covering the lid hinge and undo the 2rd screw from the driver's side (the rest all need to come out later so you can do them all now and remove the lid) Then the rear cover unclips (6 clips), start at the top with a trim tool pulling backwards. Once it is off there are 2 screws facing rearwards to remove (need a short phillips for these) and you are done with the rear of the console. There are 4 plugs at the A/V box to unclip Then there are 2 screws at the front of the console, and 2 clips (pull up and back) and the console will come out.
