Go an Ecotec.

But seriously, for most people the SR20DET gives enough power and response to get drifting. It's cheaper and gives better weight distrobution than the RB. Only in really extreme drift would the extra power, torque and response of the RB be worthwhile.

Just my 2c

Your mate and the Big R is right.. Not only is the RB25 heavier but it locates the weight further forward of the crossmember.

A VQ30 on the other hand :whistling:

That thing barely fits into a 300ZX. How the hell do you squeeze it into an S13? Very wide engine for such a small vehicle...

Your're getting the VG and the VQ series(alloy block) mixed up.. And I have seen a VG30 in a 180. Also my mate had a VQ30 in a Laurel. Was a nice fit. Banzai motorsports recently bought it as a project car. I've heard rumors of that VQ30's are lighter than RB25's. Also the single stock turbo of the VQ being of steel wheel config gives the possibility of 220rwkw :whistling:

But yeah any V layout engine in an S13 will probably create under bonnet temp issues.

i'd probably say rb20. slightly more torque than a sr20, so if you were to go into a corner, or come out of a corner, lower in the rev range the more torque would still be able to keep the wheels spinning. but it really comes down to what mods you are going to run on the engine. if it is going to be reasonably stock then the sr20 won't be as good as the rb20 because the sr takes a while to spool up due to the bush bearing turbo. however to use an rb motor you would need to change to a steel wheeled turbo, otherwise you will cook it.

Thats just plain, WRONG...the RB20DET has no torque compaired to the SR20DET...i should know, ive owned both!

The SR has heaps more low down compaired to the RB20...expecially when going for a larger turbo

SR is the pick of the bunch for an S13...but sounds like a tractor....RB note is insane!

An RB25 will have more torque though (which was the original question, and I think / hope mad082 just typo'ed).

That said, you want a well balanced car and an RB powered Silvia won't be as well balanced as an SR powered one.

were they in the same car? the r32 is a heavier car than a silvia or 180. i have driven a silvia with an rb20 motor in it, and i used to own a 180sx with an sr20. the rb20 had more low down power then the sr20. out of a slow corner the rb would pull a lot earlier in the revs. but out of a slow corner the missus' natro sr20 pulsar would beat both of them until they got up in the revs.

and i'm talking about stock motors with stock turbos, just front mounts and exhausts.

LOL!

The RB20 has no torque.

It's a 6, where the SR20 is a 4 cyl.

on the topic, whats the weight difference between an rb20 and rb25?

Would having one in a 32 make a huge difference to the weight distribution of the car?

You'll actually be suprised, but a significant portion of the difference in weight between an r32 and r33 is actually the motor and gearbox.

This goes to all of those homos calling r33s boats. I'm not just making this up off the top of my head. I did an rb25 into r ugly poo (32). After helpinng a friend out with an rb25 swap into his r ugly poo, it weighed almost as much as an r33 gtst.

So basically, to all you r32 lovers, the reason why your car is lighter is mainly because of the crap motor and crap gearbox.

Lol so much hostility dude,

They also bag our cars on the looks & how it's all bulgy, I love 33's In fact all of the skylines.

What's with all this competitiveness between r32/r33 owners? Aren't we all supposed to be united against power tripping cops & v8 bogans? :)

Why not hate on the R34 owners for owning better looking and faster cars than you? :)

[Flamesuit: ON]

There is no hostility or hatred going on here, just merely pointing out that most of the weight comes from superior parts, such as motor (and ancilliaries e.g. bigger fuel pump, bigger injectors, etc, every small thing adds weight) and much bigger box.

I was also merely pointing out that r ugly poo owners call r33s whales for being heavy when once these upgrades are installed into an r32, the weight is not that different, but at the end of the day, the interior still looks like a vn commo and the exterior is not far off a vl.

But in reply to the thread, sr20 since the car is designed for an sr. Much better/easier fit (an rb20/25 is really tight. try and find a pic of one). much better weight balance. plenty of power for the lighter car.

LOL is all I can do at that.

I drift my RB20 and no, it sucks, even my old CA18 Silvia had more torque down-low to mid which is where you most need it for drifting IMO. Apart from being annoying on the track, it's also annoying on the street as well, have to redline it just to take off from the lights at a reasonable rate. :P

I don't think anyone started bagging R33s in this thread but you straight out started to bag R32s just cause you felt like it in an unrelated topic. So because you've let your thoughts free, so will I even though they will be offensive.

Sorry but my interpretation is that whale is in reference to the whale-like appearance (small factor being weight). I knew the whales were much better value than the 32s when I bought my "ugly poo", but I wouldn't be able to live with the fact that when I stare at my car I see a whale on wheels. Ugly FAT things they are. But hey this is just my opinion and it shouldn't matter to you.

You know that is always in my mind when I think of R33s but you don't see me boasting around and bagging other models in any old unrelated topic with no mention of of it.

We all love Skylines, we should learn to be more opened minded and tolerant of other people's opinions/tastes, control yourselves guys. :D

      Baron's R34 GT-R build thread - car in Japan for 5 years -_-

      By BaronOBeefdip · Posted

      Back again. I returned to Japan in Jul/Aug to spend time with the car on my birthday and remind myself what all the sacrifice and compromise is for. It happened to line up with the monthly morning meet in Okutama, which I have been wanting to go to for a long time. It's a unique event at a unique spot with really rare, interesting, and quirky cars. It's where all the oldheads and OGs gather. The nighttime scene at DKF certainly has its place and should be experienced if you're into cars, but there's too much bad attention and negativity around it now. IMO the better time is Sunday morning at DKF or Okutama; it's more chill and relaxed. I'm glad I was finally able to go, but not sure it's worth the drive from all the way from Nagoya immediately the day before, unless I was already staying in Tokyo for the days right before the meet, because you have to wake up quite early to make it in time. Funnily enough though I didn't drive the car all that much this trip because it was just too damn hot. While there were zero issues and running temps were nominal and the A/C was strong, RBs already run crazy hot as it is. Sure, it took it all like a champ but something about driving these cars in the ridiculous heat/humidity bothers me and makes me feel like I'm asking too much of it. I'm just me being weird and treating the car like a living thing with feelings; I'm mechanically sympathetic to a fault. Instead I was mainly driving something else around - a KX4(silver) 2001 X-Trail GT, that I acquired in May. There's a few different flavors to choose from with Xs, but visually it's the Nissan version of the Honda CR-V. Mechanically it's a whole different story as this, being the top-trim GT, has an SR20VET mated to a four-speed auto and full-time AWD! It was a very affordable buy in exceptional condition inside and out, with very low mileage...only 48k kms. Most likely it was owned by an older person who kept it garaged and well-maintained, so I'm really happy with how it all worked out. It literally needs zero attention at the moment, albeit except for some minor visual touch-ups. I wanted something quirky, interesting, and practical and for sure it handily delivers on all three of those aspects. I was immediately able to utilize the cargo and passenger capacity to its full extent. It's a lot of fun to drive and is quite punchy through 1st and 2nd. It's very unassuming -in the twisty bits it's a lot more composed than one would think at a glance- and it'll be even better once I get better tires on it(yes, it's an SUV but still a little boat-y for my liking). So...now I have two golden-era Nissans in silver. One sports car and one that does everything else; the perfect two-car solution I think👍 The rest of the trip...I was able to turn my stressed brain off and enjoy it, although I didn't quite get to do as much as I thought. I did some interesting things, met some interesting people, and happened into some interesting situations however, that's all for another post though only if people really want to know. Project-wise, I went back to Mine's again to discuss more plans and am hoping to wrap that up real soon; keep watching this space if that interests you. Additionally, while working in the tormenting sweatbox that is the warehouse, I was able to organize most of the myriad of parts that my friend is storing for me along with the cars, and the 34 has a nice little spot carved out for it: And since it can get so stupid hot in there, that made it all the more easy -after I was standing there looking at the car and said 'f**k it'- to finally remove all the damn gauges that have mostly been an eyesore all this time. Huzzah. The heat basically makes the adhesive backing on the gauge mounts more pliable to work with, so it was far less stressful getting this done. I didn't fully clean it up or chase the wiring though; that will happen once I have the car in closer possession. Another major reason to remove all that stuff is to give people less reasons to get in my car and steal s**t while it's being exported/imported when/if the time comes, which leads us to my next point... ...and that is even though it's time in Japan is technically almost up since it's a November car and the X would be coming in March, I'm still not entirely sure where my life and career is headed; I don't really know what the future looks like and where I'm going to end up. I feel there's a great deal of uncertainty with me and as a result of that, it feels like I'm at a crossroads moreso now than any point in my life thus far and there are some choices I need to make. Yes, I've had some years to consider things and prepare myself, however too much has happened in that time to maintain confidence and everything feels so up in the air; tenuous one might say. Simply put, there's just too much nonsense going on right now from multiple vectors. Admittedly, I'm struggling to stay in the game and keep my eyes on the prize. So much so in fact, that very recently I came the closest I ever have before to calling it quits outright; selling everything and moving on and not looking back. The astute among you will pick up on key subtext within this paragraph. In the meantime I've still managed to slowly acquire some final bits for the car, but it feels nice knowing there's not much left to get and I'm almost across that finish line; I have almost everything I'll ever want for my interpretation and expression on what it is I think an R34 should be. 'til later.

      R33 GTR running -9 with no tune

      Also playing with fire if they start to flow more air down low than what the stock twins can. It's not even up top you need to worry, it can be at 3000rpm and part throttle and it's getting way more flow than it should.

      You still want a proper tune on the stock ECU though. Stock tune + stock ECU with GT-SS/-9s is probably playing with fire if you're running more than stock airflow/power.
