Hey all, kinda new to the skylines scene.

Anyway, I have just finished a rb20det silvia conversion. To be honest I dont really know much about the RB engines. I am aiming to get ~200rwkw mark. The main "performance" mods I have alrady had done are:

-T4/3 Hybrid Turbo

-3" Turbo Back Exhaust

-POD with cold air

Not much i know, but anyway. I will be doing a few more mods and wondering if this sounds good to all you rb20 heads out there.

-fmic (hybird or gtr)

-gtr fuel pump

-injectors (not sure which ones, whats a good set that will fit straight in? the gtr type have difference impedence, well thats what i was told)

-ecu re-map/re-program (can this be done, is a daughterboard necessary, or is an aftermarket type the best thing to do)

I'd like to keep it as cheap as possible eg standard gtr part instead of jap brand parts etc.

Thanks in advance

-Daniel

Have a question for you. What year is your RB20? and dose it say RB20 on the cam gear cover? just tryin to figure out what year I have. Mine dosen't say RB20 on the cam cover but a friend has one and his says RB20 on it.

I assume you had the SR20DET in you silvia before? If not I would definitely recommend upgrading that fuel pump asap with the T3/T4 on there. I am on my third RB20 S body swap now (bought my new motor yesterday), and there is a good chance your fuel pump might not be up to snuff. We are running JIC 3" turbo back (no cat, custom DP/FP) exhaust, stock SMIC, and intake on my buddies S14 (my second swap) and he was starting to run lean beyond 4k rpm. I picked up some of those S5 TII RX7 injectors (S5 are 550cc high imp) and will be shipping them to him soon to help out that problem. He has a SAFCII to cut them back since he is only pushing the stock turbo at 13psi, which is high for the turbo but low for the injectors.

Did you do anything for your tach? I am going to try and put a potentiometer in where the stock resistor is for the signal with a 50-100k ohm range to try and fix the 4cyl's tach interpretation of the 6cyl signal. I will let you know how that goes if you want.

Check my sig to see the cars I've worked with if you want (it's free to join that image service to view them). Page 11 is a video of my buddy's S14. The red S13 was my first one, which I ditched since it was a rather rough body as you can see. The black one is my new project.

Congrats on the swap!

    • Nah, they'll do it without a receipt, tell em roughly when it was, that it was cash, youll likely only get store credit, but that gets you some dollars towards the newer better shovel, or other item you need/want later.   Still take it back and have a crack at returning it.
    • Nah. Was just wondering if you were having a small stroke or if there was some slur/gaf/inside joke that I wasn't aware of.
    • That was a fark up, it's Salamanca Place I was thinking of. And now I'm curious as to what potential slur/gaf I have caused with Salamander Road, ha ha!
    • Actually everyone on the roads was really well behaved. The only person that did any minor tailgating was a local hoon in a Turbo Focus. Unfortunately we weren't going the same way so there was no grand initial D touge battle. Lots of people pulled over and let me through. The amount of "Hey man nice car, omg skyline, nice 34 man woo" was suprising. Like really suprising. Like almost annoying. My partner was obviously surprised, she'd never seen anyone in the real world point out the car/like the car/want to chat about the car before, so to have like 3 people per day mention it was notable, I could finally say SEE? SOMEONE THINKS THEY'RE COOL. Everyone was also pretty suprised about the weather. Every day was dry and about ~13-14C. Mount Wellington had a sign that said they close the gates at 9pm and I was heading up there at about ~7:30. It was VERY apparent that conditions were getting significantly worse by the minute on the way up and down. The road on the mountain was terrible though, it's no driving road. I have various suspension related questions now. Luckily it was only about 20 minutes from where we were staying to the top of the mountain as said Google maps. We only had the 2 nights in Hobart. We went to the Farm Gate Market though which was really good - And went down to the Hastings Thermal springs/caves down there during the day. I'd definitely be up for going back again, so luckily there's a few more sights yet to see. Didn't get to do the west coast/queenstown/cradle mountain so this was supposed to be a 'scouting' trip anyway of sorts if I were to one day do/take part in/organize a more car-focused trip. As for the boat, it wasn't bad. Well it was bad, but not in the way you're thinking. We did the night trip which leaves at 6:45 (though you have to be there ~2 hours earlier) and arrives the next morning at about 6am. There is nothing to do on the ship. If you plan accordingly and bring a book/tablet/show to watch/charger you can just chill out, take some Travacalm and just sleep through it. The food there is an extremely basic buffet that costs $32 a plate, or $14 for a $3 pizza. The way back we had a travel kettle and a few different types of cup noodles and made our own tea/coffee in the room. This was a far superior way to do it. At the very least book one of the rooms with beds. I guess as we were in the off season we didn't have room mates. You get an option for rooms with 4 beds (2x bunks) or a room with just the two bottom beds. There's also some option for a deluxe queen bed but it's much pricer. We've been on sleeper trains in Asia before so we figured this is similar (and it was)
