The rb20 and rb25 Hello, I found some info from testing done on the r32 gtst and the r33 gtst. Its often said seemingly on websites that the rb20 is a motor lacking torque under 3000 rpm and that the rb25 is better, stock vs stock. I know that the rb25 is a more powerful motor and has more torque stock vs stock rb20. But in these test I found, it seems that the rb20 in a r32 gtst stock compared to a rb25 in a stock r33 gtst is not that bad.

Cool thanks

Cool so can keep setup except for diff, not familiar with futzing expression. Whats that? So use 33 diff and housing, but put the 32 back plate on.

Is it a pain to change to a 33/34 diff? Many things have to change?

I want to have everything to help me with my acceleration as much as possible, non engine parts. Ok, little confused, you said what I learned was wrong, but you mentioned that 4.1 is what you had and you wanted to go 3.9. Yes I understand that 3.9, etc is good. I wasnt saying that the shorter gears are better. Just what I learned about 4.3 and 4.1. So you didnt like your 4.3? Would it be worth it to put in a 4.1? My engine later I am looking at is going to be a 25 or 26. Why couldnt you do a 3.9?

What I learned is that cars with a 4.3 or 4.1 diffs are good. I learned that sometimes non turbo cars have those diff ratios to help it along. I learned that 4.3 or 4.1 diffs are good to have in turbo cars. I wasnt sure what mine is. I am putting a Nismo LSD in mine. I know my car is over 25 years old and the diff is most likely not working correctly so I will put in the Nismo. I change the diff oil once a year to help keep the diff working as well as it can.

I just learned some things about diffs so was checking to see if what I learned was accurate.

Strange in the states they like them alot, there in Australia they are detested.

Man, you guys really hate RB20's

No, just checking. Learned that 4.3 is good followed by 4.1 and some people put 4.1 on their turbo cars. If the diff ratio I have is good already, than I want change.

Cool, wanted to make sure,

Hello I found this info someone put up about different Nissan diffs. Is this correct? http://www.nissansilvia.com/forums/index.php?showtopic=337751 I have learned from other places that having a 4.3 or 4.1 ratio diff is good to get for a rwd turbo car. Is this a good ratio to have?

Hello, I am going to put R33 brakes and rotors onto my car, r32 gtst. Is it a good idea to change out the cross shaped brackets and the wire clips to new ones since the calipers are at least 20 years old?

ok

Not worth it even if rebuilding?

Oh ok, thanks.

Hello, The fan in front of the ac condensor( the radiator looking thing in front of the radiator), doesn't come on when I turn on the ac. Is it supposed to come on? I have a r32 gtst.

Hello, The store where I saw a built rb26 and a rb25 still have the items I believe. They knocked the prices down to 1400 dollars for the 26 and 500 dollars for the rb25. If I buy either one of these engines, what should I get down to them before trying to put it into my car, r32 gtst. The store doesnt know if the engines work or not. They checked the crank and it turns fine I believe.

Thanks for everyone's help. How does the GTX 3071R perform on a rb 20 and rb 25? I have found only alittle info about them for those engines.

Hello I came across a HKS 2530 for only 179 dollars. Tempted to buy. It has play foward and backwards. What places can it be rebuilt? I check the HKS website and I don't see any replacement parts for the turbo.

Hello, I've check and cannot find a diffinite answer, will a r32 gtr, r33 radiator work in a r32 gtst?

Hello This thread is not about if I should change out the rb20. This thread is to dicuss the rb20 det and get peoples experiences with it. I have a rb20 det with rb25 turbo with a HKS aculator on it. My car has a turbo back full 3" exhaust plus sports cat, pod, small return flow fmic, Nismo GTR fuel pump, stock injectors and a Mines tune. Car drives cool. Positive turbo spool at 2000 rpm. Drives good off of boost and is cool. Going to add a boost controller to be able to control boost better and have it come on sooner. Its fun to drive. Don't know what its like to drive one over 300hp. Later going to get a rb25 or 26 but for now the 20 is good. Havent taken it to the track yet but will soon. What is everyones experinces with this engine and what do you like and not like about it?

How is it? Was it easy to install? Did you have to splice anything? Does everything work?

How are you getting such low spring rates? Most of the coilovers I find in Japan for the car has a minimal of 8 for the front and 6 for the rear.

I understand buying better tires, but why no 2 way? Whats wrong with HKS? Not sure how much car is lowered. I haven't messed with the height, the car is still the way it was when I got it. Already had the HKS Hyper D's on them. Its lowered some but not too much. Came that way. I know about the big brand tires, Dunlop, Yokohama's, etc but I am in Japan and they charge a premium for the really really good tires from those companies. From my experience the Federal's are good. Any model tire that is good that you can suggest? Don't want to use semi slicks for everyday driving because its rainy season now and I don't want to wreck.
