Well, at the moment I have a custom sri,vias delete, And almost straight pipes (only restrctions left are the pre-cats). If I get headers and a good tune what else would I need to get to about 260 or high 250's? Or am I simply asking too much? I'm pretty sure i/h/e with a tune will land high 240's low 250's. Nwp i.m spacers also?
Thanks

 

SSIM and technosquare ECU.. you could easily reach your goal with a small shot of nitrous

 

does anyone tune automatic's? technoquare will only do a 6spd ecu?

 

intake, vias delete, spacers, headers, cutout or open Y-pipe + tune via UTEC or TS reflash+SAFC and you should see at least mid 250s (if not higher) on a healthy 6-speed car.

 

TS does reflashes on any ECU, but you would want drop resistor mod and a TCM (like suprastick) to take full advantage.

 

I've got straight pipes once I get headers, only thing left will be tune+spacers. I'm really wanting 260s though. Lookin to see if that's possible w.o any head work...yet..

 

hahaha with a small shot of nitrous I could easily blow past my goal But i'm lookin to have a fast na w.o spray. I'm just not feeling the risk of spray. Plus it's just a favorable opinion to run w.o it. More bragging rights

 

Well peeps are in the upper 270s without head work or even cams.

 

You're probably going to want a resonator or something because when I had my OBX headers > stright pipe > 14" Magnaflow Resonator > Flowmaster 40 Series, it STILL sounded so raspy. Like Honda bees-in-a-can raspy. I wouldn't even step on it if anyone was around, it was that bad. I have a Magnaflow HFC now and it sounds wayyy better. A HFC and an 14-18" resonator would probably sound best, IMO.

Also, Jay_Pee has almost every bolt-on mod and a 3" exhaust and he is putting down 286hp, and I believe that is untuned as well. That thing is a monster and last I read was doing 12.58 1/4 mile. I could only dream of those numbers N/A!

But I am going to be doing an SSIM, 350z injectors, custom SRI (no more GAB), 255 walbro, a new MAF and a new tune soon. My MAF has always been bad and I dynoed with at 243hp which seemed low to me. I hope with the new mods and a retune I can be at 260hp. Spring time I will do a 350z clutch, Fidanza FW, crank pulley, nitrous and another retune. Hoping to see 330hp on a 75 wet shot.

 

Well atm with stock headers and no cat or res it sounds Deeep. And I love how that sounds, hopefully headers won't make it raspy. If so i'll go for a good hfc and see how that goes..286whp...WOW, wth is done to it??

 

They do Autos....but to reach the benefits of the reflash you will have to manually shift, since the trans computer will still shift at the Oem settings....

 

WOW!! news to me!!

 

I/H/3inch cattmann catback w/ testpipe, UDP, NWP spacers, S-afcII- FINALLY tuned, Technosquare L-spec ECU, timing @17, fidanza flywheel, and SSIM.

I think he said at his latest dyno, it was 272hp 270tq but I thought I remembered higher numbers before but still, that's nuts!

 

Oddly enough, since I did the NWP block plate, my car has been shifting at higher rpms on its own, usually just before redline when it used to shift at 6000-6200 rpms. Not sure why it changed but since the engine makes more power at higher rpms now, I'm glad for the new shift points.

 

Same here.... but 286whp... Idk about that w.o any head work. I'd wanna see a dyno pull haha.

 

Yeah that's great Scott! But Technosquare moves the rev limiter up to 7100 Rpm

 

But what does the power ban look like at 7k?

 

With the full spec reflash power was well beyond the Oem settings...I'm lining up this mod to be my final modification...and hopefully I'll be up there around 260-280 whp untuned...

 

Depends on what you have done. With ssim my car makes iirc over 245hp from 6300 to 7100, peak 253hp

 

I peek at 253, and I'm pretty sure I can hit 260 with my BBMAF, larger injectors and the vias delete. Also a new tune will be required.

I'd like to see that 286 dyno pull myself

 

The pre-cats are the biggest restriction. You should have gotten headers before doing any other exhaust work.

 

I don't have enough mods to make a 7100 rpm redline worthwhile but the car shifting pretty close to stock redline seems to be perfect right now.

 

In for the 286whp dyno. Have run files?

 

A 3" exhaust is really, really going to help you. That 286whp pull everyone is talking about was done with a 3" setup. You will have no issues hitting your goal with an 3" plus what you have listed.

 

286whp lol yeah ok and im santa clause

 

hey i want G37 19s, 5.5 headlights and a new system

 

Like I said, I thought I saw 286 in a dyno or somewhere. If you want to know for sure, PM him. I don't mean to spread any false info, but I really thought he had it in his sig or something at one point.

 

yeh there was a 28Xwhp dyno from that car IIRC

anything's possible, hard to believe but possible

 

I dont know why thats really questionable. sr20den put down 272 a while ago, and that was definitely not w/3" exhaust

 

would it be possible to hit close to that 240-250 with intake all nwp manifold parts y pipe safc2 and 2.5 cat to axle with hks axle back, or is it necessary to run headers.

Sorry O.P Just wonderling lol.

 

!!!!!
jk, you're good haha.

 

I'd say 230 with a good tune. Headers tunned properly offer about 18whp iirc.

 

tuned cattman headers gave me >40 horsepower

 

heard. I need to find a good dyno place for tune.

 

OMG amazing... Im just dreading the 6-8 hour install lol, I can afford them I just dont have time.

 

You can pull it off.

If you wanna get SSIM. You'll need to get the Z33 CVTC maps & raised rev limit on your Technosquare reflash.

After you do headers and a 3" cat-back, you could also try to get an AFPR and with a wideband and VAFC, you can squeeze more timing advance out of your car too.

 

What Whp level do the stock injectors begin to lean out? I'm sure they can support 300 or slightly above 300 whp....

 

I thought he had cams.

 

People run up to 5psi of boost on the stock injectors...

I have the mods in my sig, and trapping in the 107 range in the 1/4 N/A (puts me around 270-275 whp according to most drag time calculators), and I am still having to pull 15% fuel up top... at no risk of running lean lol.

 

i think my injectors are at about 75% give or take a few. Another member on here with an auto was just over 75% and the MAF was maxed out at close to 5 volts. he pulled 240/240 ish
