Looking to swap in a SR...what is the stock type performance really? - Page 2 - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

blackej7 · 09-21-2009, 10:39 AM

in my opinion, if someone complains about stock sr, its probably not installed right, or your missing stuff. like... not using an o2 sensor, or a knock sensor, or your timing isnt set right... or your running wastegate pressure, not an mbc, or there are boost leaks, or vacuum lines arent right... or SOMETHING. people often overlook simple stuff.

a stock sr that is properly installed and running right is very fun. no shit, its not crazy fast... but lots of fun.

S14_Kouki · 09-21-2009, 10:40 AM

Why v8's?? Its a foreign car why not stay with a foreign engine. If you want to go fast for cheap get a 1j or 25 swap and just turn up boost.

i have had a stock SR for 2 years now. i don't get sick of the power. usually i get sick of power and feind for power upgrades, i haven't even done any power upgrades in over a year. I've been upgrading brakes and suspension. i'm satisfied with the power, my estimate is around 230whp with no tuning. my car looks like ass and you cant' see the intercooler, it's fun to see the look on evo owners faces.

either route, i don't know why you're saying you don't need a bov or FMIC, they will make things much better. lol i have an SMIC and no bov (capped off pipes) and am realizing that i do need them so those are my next upgrades.

i just have an MBC, boost to around 13-14 psi, occasional spikes higehr than that. but i have a toda flywheel and 1pc steel driveshaft, exedy stage 2 clutch, and s15 helical lsd.

thing is a BLAST to drive, i had to build this car tot he way i want it because there is nothing available like this car. well except now the hyundai genesis.

from yoru postings, it seems like you don't EXACTLY want to do it yourself to get this experience under your belt, but it you're lookingl ike a simple bolt in, yeah SR is the way to go. if you want to learn alot, and piece together a turbo kit and buildup your stock engine, and spend basically the same thing it'd cost for an S14/S15 sr engine set, then do it.

i say s14/s15 engine set because they're newer, will come with a bigger better turbo, would have less mileage, and you already have an s14 chassis. sure you can get an S13 redtop or typex blacktop, if you do, make sure the mileage is proven.

^*shrug* it wasn't my car-just sharing my experience w/it...and to clark-i didn't say it was a good set up, i was simply describing the setup, since the OP is talking about having a stock sr to drive around...and the reason i'm opting for a ka-t vs. an sr is because everyone and their mama wants to do an sr-so sue me for wanting to do something a little different...and yeah i have ZERO experience compared to most other ppl on here but hey, you gotta start somewhere.

don't get butt hurt. i wasn't being mean or anything. i was merely pointing out that something was wrong with your setup, because i'm trying to avoid some 16 year old googling and finding your statement and becoming mis informed.

Sorry for the semi off topic,

Smoking rolled up pages of exotics from the Dupont registery maybe. Unless the driver didn't want to push his car,have the skill or waste his time with you. What " exotic" car where you "smoking"? I said my opinion a stock SR isn't fun. It's a fact a bone stock SR (exclude S15 model) in an average S chassis cannot out perform a VQ35 in a A chassis.(acceleration wise) I have both cars so I'm not bais toward either.

jspaeth · 09-21-2009, 06:59 PM

You asked what's the performance with an SR.....

With a stock blacktop SR with supporting mods (big IC, BOV, etc, etc, etc), boosting the T25 at 14 psi, in a 3000 lb S14 (including me and gas),

I ran a 13.5 @ 100 mph with a 1.9 60'.

People that are good drivers with lighter cars have gotten into the 12's with stock SRs.

what lifesle, essence,culture,spirit is that....stealing your money on high cost performance mods...

jspaeth · 09-21-2009, 08:11 PM

IMO, American cars versus European/Japanese is one of "brute force" versus efficiency/refinement.

It's like if there's not enough power, just add more displacement!

Shitty ass 7-liter V-8s that only put out 350 hp. Weak.

Obviouslt the newest Corvettes are (finally) well engineered, and handle well....still can't take the Kmart interiors though.

Bubbles · 09-21-2009, 08:33 PM

If you don't find a stock sr exciting you sure as FUCK aren't going to enjoy paying 2-3 times as much and basically getting the same performance.

you're clueless. get back inside your maxima and move some family members

great generalization. just in case you forgot, american cars were considered the cream of the crop way back in the day.. which is much more than can be said about other countries and their vehicles. what i am trying to say, is numerous countries (let alone individuals) have developed some very unique and fantastic cars.

you on the other hand, are stuck reading too many magazines that review cars like "ford contour svt vs honda prelude vtec" ... get over it, there are a lot of nice cars out there. not saying that america hasnt produced a zillion shit-rides in the past decade or two, because they have. this happens to lots of companies that get too fat for their own good.

c6 corvette interior is fine, ive sat inside and they feel fine to me.

like i said, every car manufacturer has their flaws.. look at the nsx. all your talk about efficiency and these fuckers on the nsxprime forums still get upset because they spend tens of thousands in upgrades and still get their asses handed to them by some viper or z06. again, not saying the nsx is a bad car.. but that v6 is dated after that 10+ year production run, wouldnt you say?

i prefer japanese... correction, i prefer 90's era-NISSAN cars because they give you a good balance of performance and cost-effectiveness, so i dont feel guilty if i crash the fucker or if it gets stolen. ide probably want to hang myself if my brand new 60,000 dollar car gets stolen/smashed....... and in case you forgot, nissan's latest mousetrap is quite expensive at 80k+ and is difficult/expensive to tune.

just to get back on topic a bit...

what's needed to up the boost to 13-15psi on a T25? what has to be done to swap in a T28 (I want to go GT2871R eventually, but see T28's pretty cheap a lot)....

Huh... Then why is it my stock sr with an s15 turbo off wastegate is dead even with my buddies 350Z?

ah above 12lbs boost on a T25 you are out of efficiency curve. Its basically blowing hot air that point. Ya guys will tell you they have boosted 15lbs on a T25 but is 15lbs of wasted effort. You want to go 15lbs bolt on a T28.

Though I still feel upgrading the injectors is a good idea as well. There is a reason the S15 had 440 injectors. Of course if you do that I also suggest a different MAF and a good tunable ecu or a ECU Flash.

More fuel more air flow more power and higher boost capability. Of course everything has it limits internally as well.

You want to play you have to pay.

That first quote should have been what's it take to go 13-15lbs on a T28...

That seems like a cheap swap.

So injectors, maf...with the stock ecu handle that or is that tuning time?

I am planning on adding to this as I go, I just want to get some power under the hood as that's the only thing left.

It sounds like just a stock SR20DET with sidemount even would be fun to start.

LMAO, I can't believe somebody actually said that.
Sounds like something out of a corny anime with bad engrish.
Feels a bit out of place when comparing automobiles.

SPIRITUU!!!!!!!!

Anyhow, I have a close to stock, S14 SR in my S14, making around 10 lbs.
It makes decent power at 4-5k.
The powerband isn't all that smooth, but it delivers ok when it does.
I definitely need a tune, but overall I'm moderately satisfied.

ixfxi must be an exceptional driver if he can drive well in the twisties with a 240 w/ an sr.
With stock suspension, open diff, and SR, I found my S14 to be the most difficult and unforgiving car ever.
With a helical diff & stock suspension, not too bad.
Even with a modified suspension, I find it's difficult to get enough grip and feedback at times.

I like to play with drivers on Mulholland canyons.
Shitty drivers w/ good cars don't mean much.
I can keep up with my mom's hybrid.
Good drivers w/ decent cars, probably.
Good drivers w/ fast cars, probably not.

AutoX, I'm usually within 4 secs of the fastest cars on an approx 40 sec course.
Really need to take it out to Streets or Buttonwillow & time it.

Guess I am spoiled with driving an underpowered miata prior.

well you could do it without injectors or maf but you start pushing your AF ratio in my opinion with even the T28. Injectors a Maf and ecu tune are insurance. It gives you room for more power and protects your investment by not running your injectors at full duty cycle and not pushing air flow ratio on your maf.

Now how you do the ecu tune is on you. Either by buying a tunable ECU or getting your stock SR ECU flashed for the injectors and MAF.

I am thinking Enthalpy because they are pretty local.

thats the n00b mistake i made back in the day, installed an S15 spec-r turbo thinking because it bolts in that it wouldnt require tuning. YEAH RIGHT

anytime you make a change, you need to have your car tuned properly. turbo isnt an intake, exhaust or header.. its a fucking turbo. every RPM the motor is tuned for a certain amount of fuel and air, and the turbo changes the ENTIRE equation.

my car still ran, but it didnt create any top end power and needed tuning. lesson: get your car tuned properly after changing turbos.
