Quarter mile times

1991 Nissan Silvia K's FMIC, 3in turbo back, cusco LSD, all stock other than that...

13.08 @ 104

[kentuckyslider]

My best times with my old setup. The 60' and 1/8th mile were on the same pass but my best 1/4 time I ran a 7.69 1/8th with a 1.68 60'.

11.87@116 1/4 mile7.61@91 1/8th1.55 60'

All of this with a GT2871 with stock head and cams with built bottom end on 21psi(345whp). 26x8.5 Et drags, 4.36 R32 diff, and Ksport springs with oem struts.

My holset setup is much faster but I don't know if it will ever be quicker in the 1/8th or 60'. Once you cross over the 425-450whp line it's really time for a Z32 transmission swap if you want to launch as hard as I have been. I'm going back to ET street radials because I'd rather spin a little then break alot!!!

[DrifterProdigy85]

12.0 @ 130mph 2.0 60ft. Spinning in 1st, missed 2nd, then took a second or so to build boost again. Shoulda been a high 10 second pass but they wouldnt let me run again. Damn roll bar requirements. lol.

I thought the NHRA rulebook doesn't require a roll bar until you run 11.49 or quicker?

Or is there a mph rule that I'm missing? I know you need a full cage if you run 135mph or faster, regardless of what your ET is.

You will definately be in the 10's with a 130mph trap. Do you have a Z32 transmission?? If you don't you're gonna need it with that kind of power.

[DrifterProdigy85]

Theres a mph rule for 130mph. And im still on stock trans. I dont go to the track enough to spend money on a Z trans yet. I keep it a street beater right now. Stock transmission works fine for that so far.

[2_Liter_Turbo]

I've been launching hard on the stock trans (with slicks or drag radials) for 3 years now. Still works great, lol. I'm no 10 second car (yet), but still... 12.0's with 1.7 60 ft's (not the greatest, but still decent) still put some use in it, lol.

where did you run???

Whoever kicked you off the track must not have been up to date on the rules. There is nothing in the NHRA rule book that states you need a roll bar if you trap 130mph. Just 11.49 and quicker.

[DrifterProdigy85]

The time slip guy said something to me about it. Maybe he was new and got the 135mph rule mixed up with 130mph. Im gonna go back pretty soon and try for a clean pass.

[impact240sx]

It seems like alot of people get very slow et s with stock sr's. When mine was stock, only tiny fmic, my car would pull on mid 14 sec cars like crazy.

Anyways, I really can't wait to see what my time is, because I've been told that I had a strong sr even when it was stock. So do you think that mid 12s are possible with my set up

S13 red top-18 inch 225s in the back-Welded Diff-ssqv-Tomei Headgasket/ Arp Studs-Megan Ex mani-Small Fmic-Isis intake mani-Walboro 255lph-Brian Crower Stage 2 cams (264s)-Aluminum 1 piece drive shaft-megan motor mounts- 2260lbs Gutted interior only dash and door panels and heater core, but no ac tunnel or fan assembly-Carbon hood-Stock t25 I'll prolly run 14psi first pass but 17 after that

I'm really hoping for mid 12s and from cars i've messed with it seems like it, for instance some guy in a lotus elise did a ricer fly by and I cought him and pulled lengths on him on 14psi, I've also pulled on a few newer vets (03-04?), also held a viper, and a 67' camaro 454 (I thinkk it was built cuz it alost pulled a wheelie at like 30 mph lol) barely pulled a length on my car.

I'm tryin to go for the fastest stock turbo sr 240 but I really don't know of anyone in the 12s with stock turbo.

[2_Liter_Turbo]

Your SR isn't stock, so you're going to have to pull some stuff off, lol. last I heard, SR's didn't come with 264 cams, lol.

I ran a 13.3 @ 107 mph on street tires at a high elevation track with my old black SR, all it had was a FMIC, MBC and a s***ty exhaust on it. That's it as far as power adders. Full interior, and it even weighed more than stock because of the skyline tail lights that were on it when I bought it. With slicks, high 12's were no problem.

With a decent driver, you should be able to hit 12's just fine, however with a SMIC, you are going to get a lot of heat soak...

[DrifterProdigy85]

Fastest ive heard on a T25 and S chasis was a 12.8 or 12.9. I cant remember who did it though. He pulled a 1.5 60ft on slicks.

[DrifterProdigy85]

That 454 must have been completely stock because if it had a cam and decent heads then it would be doing near 500hp. Back when i had 350whp, i raced a 69 Camaro with a 427 from a roll and i couldnt catch him. He runs low 10's, almost 9's with it. He might spray.

[Emperor_Tha]

I don't see why not. I was able to pull a 13.5 @ 104-5 @ 7psi on the t25 with a safc tune. Did consistant 13.6-13.8 at around that speed.

I did go back to the track, 15psi with meth/water. Injection with a safc tune. But my clutch was retarted. It would slip all day from 2nd to 3rd and 3rd to 4th only at the track. I was able to get 14.0 @ 85 all day long just coasting the last 3/4 of the run.

I'm probably going to the track today with the new s14t28bb. Hoping for 13.0 or better.

[impact240sx]

Your SR isn't stock, so you're going to have to pull some stuff off, lol. last I heard, SR's didn't come with 264 cams, lol.

lol I said fastest STOCK TURBO sr. lol

[impact240sx]

Fastest ive heard on a T25 and S chasis was a 12.8 or 12.9. I cant remember who did it though. He pulled a 1.5 60ft on slicks.

What all was done to it? Was It a stock sr, or a modded sr with a stock t25?

[DrifterProdigy85]

Stock everything and just tuned from what i remember. Something aroud 250whp. Im pretty sure the guy is on Freshalloy somewhere. He ran that time years ago though. Its really nothing special. Just means his car hooks up really good and he can drive his a** off.

[impact240sx]

Well that makes me think I might actually be able to pull of a 12.5 if not low 12s, thanks

[spanishricer]

No offense intended...but what's the point of trying to be the fastest "stock T25" 240sx?

That's like saying you've got the best 9mm small arm, but then everyone else is carrying around assault rifles.

[impact240sx]

Oh its call I see where your comin from, Its not like I'm gonna run around tryin to say I have the fastest t25 sr, Its just I see too many people just slapping a huge turbo on and running the same times they could of gotten with a stock turbo wit a little enginuity

Also I wanna be a little differant and see exactly can be accomplished with a stock turbo.

Last but not least, one of the reasons why I prefer little 4 cyl to v8 is because of efficiency, so I'm trying to be as efficient as I can with my turbo. If forsay you run a fast car and have a big turbo the person will be like, no wonder you won you have that huge turbo, now if you still have a stock turbo, they are gonna be like wow that's diff or didn't see that coming, I guess its partially a respect thing, idk maybe I'm just an idiot for not wanting a big turb, sorry for rambling lol.

Plus the no lag thing is rather nifty.

Well, I got 9 passes total tonight in Medford, OR. I was trying to break into the 11's, but it just wasn't happening, ha ha. If the elevation was a tad lower, I think it would have happened (Medford is at 1450 ft). The car was hooking pretty well! A few of the runs weren't the best, but overall I had a lot fun! Here are all my passes, and in order!

12.089 @ 110.30 MPH; 1.666 60'12.045 @ 110.69 MPH; 1.660 60'12.069 @ 110.60 MPH; 1.686 60'12.065 @ 110.90 MPH; 1.700 60'12.296 @ 110.03 MPH; 1.835 60' (Spun a little too much on the launch)12.028 @ 113.34 MPH; 1.655 60'12.082 @ 113.11 MPH; 1.694 60'12.136 @ 113.28 MPH; 1.729 60'12.548 @ 108.59 MPH; 1.811 60' (Missed third gear completely, and fell out of boost)

[DrifterProdigy85]

Impact240sx, are you running a Z32 MAF and retune? How much power do you put down? Im curious to see if that intake manifold and cams actually hurt the power level of the car.

[impact240sx]

I'm runnin stoc maf and no tune yet. I wanna dyno, and drag my car but i'm still waiting on my tomei hg and oem oilpump, powersteering pump, and a new oem iacv.I drove an sr 240 boostin 11 psi with a walboro and it was garbage compared to mine. I think i just got one of those factory freaks, cuz my car is deff faster then it should be. But I'll keep ya posted if i can get to a dyno soon.

Also ELNEGRO what setup are you runnin, those are some nice times

[DrifterProdigy85]

Definitly get it tuned, the cams and intake manifold probably doesnt agree with the tune of the stock ECU too much. Also stock MAF maxes at 250whp, unless you go to a Z32 you wont be seeing hardly anything higher that that.

[impact240sx]

OH thanks I really did look at it that way, My motor ran really strong with the cams, but i havent drivin the car with the new intake mani. I'm leavin for basic training in 3 weeks, but after I get down to fl for training I think I will get a z32 maf, and I also have been wanting to buy emanage for a year now.

[DrifterProdigy85]

Skip the emanage and spend the extra on a Power FC, standalone should be the first upgrade done if you plan on playing with your engine for a long time.
