yeah its "normal" for older cars to have play, but only because the parts are wearing out. I would go ahead and replace it before it becomes worse and an inspection issue

Something that every tech checks at a track day event - whether your bearings are in good shape. Yours are not. Replace them.

Also check axle nut torque just to make sure that's not loose.

Beat me to it. That happens more often then not.

Anyone have a B&M shifter laying around? I need to know if I have all of the hardware for mine.

[hOngsterr]

would anyone know if running a

235/45/17 front 255/40/17 rear on 9" affect anything on a s13?

i usually run 40's

unless i run 245/40/17 squared or 245 front and 255 rear.
planning to get some RS3's to replace my worn down RS-R's

Affect anything? Well, you will have less grip up front if you switch from 245 to 235, but I doubt it will be a huge issue. Or do you mean you are getting a taller sidewall? Re-word your question if you want more help.

doesent matter if he is going with a smaller size tire 235v245 because hes going with a much better tire. he will have MORE grip in the front with rs3's than with the shitty federal tires.
235 40 17 is closer to factory diameter (speedo calibration) than 235-45-17 series.

[Rich260z]

Front tire diameter doesn't mater for the speedo, the rear does. Both tires sizes listed are larger than factory by maybe half an inch (24.7" is stock, your sizes are about .6" and .3" larger respectively). Both of those sizes work for a 9" wide rim. In a racing application, a larger diameter front tires has more area to lay down and will be less prone to heating up. That means the fronts will grip better "theoretically".

Will that matter on the street? No

Is there a difference between the clutch mechanism between KA/SR and RB20det clutch fans?

I plan on installing a GKTEC fan for better airflow and am wondering if I could get away with using KA/ SR Clutch fan components rather than buying a more expensive RB20 Clutch fan and also having to buy the specific GKTEC adapter for RB series motors.

Insight is appreciated.

Is there any difference between the valve covers of an FWD SR20 and a RWD?

okay, im running 40 sidewall, so RS3 doesnt offer a 40 sidewall for 235 only 45. So im asking for options if i should just run 245/40/17 front and 255/40 rear or 245 all around, i dont want to run 255 all a round since i've done it before and do not like the steering feel in front. If i were to run 235/45 would that do anything

im not really good at figuring this out, so are you just talking about the 235v245 or are you pointing out what I was asking?

About the sidewall being 235/45 vs 235/40 difference wise if i were to run it
or should i just go with 245/40

thanks for the words fellas.

theres a few to name, but heres a link

RWD SR valve cover wont fit FWD SR? Explain...

[Rich260z]

I'm pointing it out in general in sizes you chose. Personally I'd go with a 245/40/17 up front, and then you're 255 in the rear.

But right now I have 245/40/17 all around and I love it since I can rotate my tires.

[KiLLeR2001]

10mm difference in tire is not worth the trouble, IMO. I have 17x8.5 and 17x.9.5, I run 225/45 and 255/40 respectively.

Your best bet is 235/40 all the way around. This will give you a true reading on your speedometer. If you run 235/45's your speedo will be about 5% slower, although not the end of the world.

What is the capacity of the stock SR20 lower oil pan?

how easy is it to install a transmission?

Depends on how mechanically inclined you are.

Not too difficult for most. I've done it so many times by myself that I can pull and swap in about 4 hours depending on how many times I get side tracked.

Does anyone know the difference between S15 ecu QT or NQ, if any? Thanks

[soundboy]

What's the best engine ? Sr20DET
S13, s14, S15?

Also can transmissions be interchanged with the various sr20?

So I just got my head rebuilt for a ka24de. It was warped really bad so the machine shop took off .015. Do I need a thicker head gasket or should I be ok with a stocker. And if so who makes em

It looks like there are various part numbers for the "QT" ECU.

91F01 - SR20DET M/T from 01/99 to 07/99.
91F05 - SR20DET M/T from 07/99 to ?. Specification says "AIR CON VA".
91F06 - SR20DET M/T from ? to ?
91F07 - SR20DET M/T from ? to ? Most likely Specification will also say "AIR CON VA".

Looks like the only difference is with new year models and whatever AIR CON VA means. A/C included perhaps?

The only "NQ" ECU is 91F08 which is most likely the last revision of ECU (probably year 2002) for the SR20DET M/T.

Cometic, all others suck(well are not as good, just different or lesser or not quite as good, or maybe just a c-hair not as good, or, well you get the idea and stop smirking, you know this made you laugh)

[mad-240]

Ya dose anyone know what brand to go with on the the adjustment for your toe, traction ,and tension thanks

[Mr_Flamenco]

when it come to arms i highly suggest get a good quality arms,
not those cheap ebay stuff.
these greatly affect handling and breaking them at high speed can be dangerous

I personally got Drift works, but cusco and power by max are good as well

it depends and what is you want to go for,

there are basically 3 models of SR20DET:
Red Top on S13 (5speed transmission) 205Hp

Black Top on S13 and S14 (5Speed Transmission) 205Hp

and the MOVIC (similar to toyotas vvti) Blacktop on S15 (6speed Transmission) 250HP


for drifting best would be Black top, because of very strong internals, RedTop has similar internals to the BlackTop but has smaller O2 senser and and other mind stuff which could be replaced.

in terms of Transmission, yes they all could be interchanged nevertheless 5Speed from Blacktop or Redtop would be best choice for drifting.

it all depend on what you want to do with the engine,
I hope that helped
other people might have different opinion.

[tengo240]

so i pulled codes from my ecu and at first i got 55 , so i went to start the car but while pulling codes the battery was dying and cranking it over killed it. So i jumped the battery and redid the codes and got code 11 ,the cas. now im not sure if that was an actual code or if it was because the battery died while trying the first time? either way i cleared everything then drove the car and it still does the same stuff . all i really changed was the engine harness (chasebays ) and pt my chassis harness behind my dash .I have looked over my chassis harness dozens of times ,relays ,fuses ,grounds are all good .
I have had to repin the chasebays harness for the maf ,so far the ect plug didnt match,none of the trans plugs match and now this whole deal .

im pretty sure that the speed sensor is in the tranny, not the rear hubs. it is calibrated to know that the wheel runs a certain length under a full revolution based on the diameter of the wheel as calculated by the sensor. changing the front only to a taller tire will cut the speedo difference (about 5% 40vs45 series) with running a taller tire in half. (about 2.5% faster than the speedo is reading)

so that means stick with a 40 series?



So i been driving my SR20DET and sometimes i acts up, when it does, it
feels as im brake boosting. Any ideas? (i know that's not alot of info, but thats the best i can describe it due to it only happening sometimes.)

Haha yea I looked into cometic but im not so much worried about what's good or not more so if and who makes a "thicker" gasket. And if I need it. .015" isn't alot but I'm wondering if it adversely affect my cam timing and if it will interfere with the pistons...

Just make sure the machine shop can do the finish a cometic hg requires to seal.

Most people popping HG's are lifting the head not blowing it out. Money spent on ARP's would be a better investment.

other people might have different opinion.

The s13 and S14 Blacktops are not the same.
S14/S15 blacktops are similar. VTC is nothing like VVTI.

S13 Redtops and Blacktops are similar. T25.
Differences are in the wiring harness and ECU connector(late blacktops).
Advantage to the S13 blacktop is it's newer. The minor refinements usually aren't noticeable.

S14/S15 Blacktops have T28 and VTC on the intake cam.
Differences are in the ECU/wiring harness. Fuel injectors in the S15.

The Highport vs Lowport head BS is from FWD motors which are different than the ports on RWD SR20DETs.

I would go blacktop no matter S13/S14/S15 just to get a newer motor. Better condition. S13 vs S14/S15 Depends on cost vs power. The T28/VTC makes more power stock but the motorset will cost more money.

S13/S14 transmissions are identical for general comparison. S15 Uses a 6 speed that uses a different Flywheel and is a different length. The stock 6-speed doesn't have a speed sensor as it uses the ABS. There are Nismo transmisson kits that come with the speed sensor port.
The bellhousing bolt patterns are the same so you can swap them.
