200sx question

[jazza08]

Well any model GTST that has steel wheels (think r32 might) can run higher boost, the other GTST turbos (33/34) have ceramic turbos which means that it will crack under to much boost... not sure what wheels the t28s have and not sure whats safe on them, generally dont have to many kms on these units so can run higher boost through them anyway

Its not to do with the b/b or bush bearing nature of the turbo, its to do with the compressor/exhaust wheels on them

Someone feel free to correct me if im wrong?

[whiteknight]

does that mean if you put a t28 turbo on a skyline you should be able to get 225rwkw, most likely even more( because of 2.5L )?

[Bazelinez]

R32s have ceramic turbos as well...

T25,T25g,T28 are steel wheeled turbos

As usual, I'll correct you.

R32 - R34 GTST/GTT all have Ceramic exhaust wheels.

R33 series II and R34 GTT have a form of plastic Compressor wheel (the wheel on the front on the air filter side of the turbo)

I believe the R32 GTR also has ceramic exhaust wheel. not sure about R33 GTR.

that is why people tend to upgrade to N1 turbo's which are steel wheel.

R32 GTST - R34 GTT (all single turbo skylines) all have Ball Bearing turbo's.

Whitenight - no.. it does not mean you can get 225rwkw out of a T28 from an S15 when on a skyline.

The S15 turbo will be a downgrade to the RB25 stock turbo.

it is smaller and will flow less.

it is also a different bolt pattern which would require more mods to fit.

S15 turbo's are good upgrades for CA18's or SR20's from the S13 range.

and usually also go good for those that Turgo charge their 4agze which is the 1.6L supercharged toyota engine.

You need to get over urself mate

I have seen a dyno of 215rwkw on an s15 with a t28 b/b turbo, also did have cams and on an rb25 it may make more power due to the engine... but thats really really at the max of the turbo mate, its not usual to see that kind of figure!

[TTT]

as I said, an S15 turbo will be a downgrade if put in place of an RB25 turbo on an RB25.

ok I am over myself.

do you think that you can now stop posting incorrect facts?

across many threads?

[jazza08]

What you believe as a correct fact in regards to a WRX vs R33 could also be regarded as incorrect unless you have both cars in stock standard form to compair?

Do you think you can stop laying into me about trying to help, its not as if i said this is how it is hints y i asked for any1 to correct me which you wanted to do in a smart ass manner... wouldn't of said anything if you would of said 'actually Jazza r32s also have ceramic turbo's' instead of ill correct you again.

Dont think im asking too much to not get attitude do you?

[TTT]

yah fair enough..

I'm just being sour cause I'm still at work..

sorry fella

[jazza08]

No hard feelings mate thanks for the info!

[Cain]

the ball berring means, that when u are say 5600 rpm (ie highish rpm) that when u put flat again, the bb unit can catch up quicker then the bush unit. ie less lag. other then that, some bush units have put out more power then bb.

[TTT]

I'm sure that there are more advantages to having a ball bearing turbo than just the fact that it can bring on boost faster than non ball bearing when in high revs.

[GTR-Ben]

About 200kw with those mods. Have seen higher with more with the stock turbo..

[scathing]

Scathing -  

yeh that would be Brentons right?

I think he had in the region of 225 rwkw with a lot of other mods apart from the turbo.

Scathing, if you are the same scathing on other forums, then you'll know Dale.

and I think that night you were hitting 14 flat in the tree fiddy... if that is you..

Yep, and yep.

Very unimpressed with my ET. There's definitely more in the car, but after I set the 14 flat I just got a little too excited trying to break my NA light-tune barge into the 13's, and ended up screwing up the next couple of launches.

I figured you were talking about Dale before. The other thing about Dale's car is that his suspension is set up for the track. He did soften the dampers out and run lower-than-normal pressures, but the rest of the geometry is still very circuit oriented.

And he was using the D01J's which, with their ultra-stiff sidewalls, aren't the best drag tyre in the world.

[TTT]

bah... your car is also a track car rather than a strip car.

otherwise it would be "350 strip" rather than track.

I'm sure you had more fun at wakefield than WSID anyway.

yeh I forgot he had his Tein's in..

I wanted to go again but mine got stolen so no go.

anyway..

[scathing]

I had an awesome time the last time I was at Wakefield. It was raining, so it was sideways city.

And yeah, my car is a lot more cornering oriented than straightline oriented. Just the way I like it.

[TTT]

the only time I got down there, it was a good day.

Greg (not old man but the other one... Sellby I think it is (the suspension dude)) was there and he helped out a few of us first timers.

anyway, after a few soggy laps in my S14 with S15 stock suspension, I parked it and went for a drive with Dale.

after seeing/feeling the way his car taking the corners with the teins and DJ01's, I didn't take my car back out.. I was quite scared being in his car and the corner speed and late braking that he could do.

Brenton was there and he put on a set of yokahama slicks.

hahahaha

I had asked him to take me for a spin in his at lunch, but after experiencing what Dales car co do with less power (he had his boost controller down to 11psi) and with just semi slicks, I chickened out of a ride with brenton..

hahahahaha

my s15, 170rwkw. ONly mods is ehxaust, boost went up from 8-10psi on factory setting, ran a 13.4 @ 106mph with 18s.

[fsmout]

Yeah s14 i would say 170rwkw to 180rwkw and a 1/4 mile in the mid to high 13's...just my 2 cents

My mate has these mods and dynoed 160rwkw but that dyno reads 10% low, so it will also depend on the dyno you get the reading from, gear, tyre psi and dyno mode etc.

[whiteknight]

so would it be debatable that a 200sx with those mods be faster than a rb25? or no way?

[jazza08]

An s13 (sr20det) is marginally faster mod for mod than an r33/34 rb25. Power to weight ratios bro But you can always put a bigger turbo onto an rb25 than an sr20, so if you went crazy the rb25 would be better
