sc61 is already on the way...atleast i think. I'm not 100% on the specs due to the fact that turbo specs confused the ever living shit outta me. I dont have the patience to learn what means what.

btw, what does FWY mean?

Paul2x · 06-18-2007, 11:33 AM

Anyone want to trade their .86 housing for a .64??

I know some of you would rather have the extra responce, but my particular set-up won't allow me to run the .64....so the oppertunity is open to anyone that has wanted to switch.

PM me if interested

My turbo is mint , was on the car for 1 day =)

OBEEWON · 09-06-2007, 10:53 PM

Went to the dyno today....and all night. Car could not put down more than 277whp. I was at 14psi. My A/F was reading 14.8!!! I have Apexi N1 duals so we disconnected it and stuck the sniffer in the cat(straight pipe) still read 14.8. Change sensors on the sniffer and stil 14.8. clearly sniffer is broken, but Im still pissed. 277 at 14psi rich or not sucks johnson. It was a dyno jet.

Mod list:
2871r .86
272 in/ex cams
TI Retainers/Springs
PE Metal HG
Spec Stg 3
Enthalpy
Z32
Megan Manifold
Megan FPR
SAFC II
Greddy Profec B
740cc Deatchwerks
Z32 fuel filtr
walboro 255lph
Apexi N1 Duals
NGK step 7
Still internally gated (yeah I know)
etc.

Something is definitely wrong. Fuel pressure is at 44-45, boost 14.
Seems not to be able to go any higher for some reason?? Someone please shed some light...

*fliprayzin240sx* · 09-06-2007, 11:04 PM

How the fuck did you only put down what T28s would put down? Check engine health yet? Compression, boost leak? I put down 320 with a boost leak at 14 psi on a smaller trim. But damn 14.8 AF?!?! If thats true, im surprised your rods not knocking yet...or worst, your engine making extra oil drains on the block.

Yeah this is retarded. I know its not 14.8 because there was a huge black spot right behind my exhaust and the whole bumper was black with soot. It seems more like 10.0!! I dont understand the numbers either. Its impossible. I know butt dyno's arent acurate but it does not feel like 277, even so... I dont know. Anyone want an S14, im bout to be done. I got street tuned earlier today and it was 12.0 all the way across so I know the sniffer is bad, but I cant stop trippin over these numbers!!!

*fliprayzin240sx* · 09-06-2007, 11:23 PM

Compression check and check for boost leak, make sure its not the engine. I was running basically the same setup up you got, just smaller trim with Enthalpy rom tune w/ safcII.

j20accord00 · 09-07-2007, 12:07 AM

dude not to be a dick or anything but just trying to help out. my buddy made 343 blacktop bone stock, no cams, no headgasket, AEM EMS , greddy intake manifold gt2871r .64 hks wastegate internal gate. greddy front mount, tanabe exhaust. tomei 555 injectors. Literally everything else is STOCK.

my new setup is upgraded to the .86 i hope i wont be disappointed. Enthalpy tune. greddy intake, external gate, sard 850 injectors, JWT C1 cams, valve springs, retainers. built bottom end, mahle pistons, all ARP hardware 8.5/1 compression, 87 bore.. greddy front mount blah blah blah..so ive been told be a few knowledgable guys, CodyAce for example i should clear way into the 400 mark 420ish hopefully. idk man i would double check everything jus dont get over exhausted about it and give up. my car should be running by the end of this month id be corious to talk to you anyways about ur setup vs. mine. shot me a P/M or email [email protected] AIM J20accord00

DrifterProdigy85 · 09-07-2007, 04:43 AM

I suggest you buy a Wideband for your personal use. Im hoping the dyno wideband was broke because 14.8 AFR is motor blowing lean. And yea you should be putting down over 300whp @ 14psi. I know i did with a slipping clutch. You may want to think of a retune if the new wideband reads really lean too.

Did a wide band tune earlier yesterday. 12.0, making sure again today. I want to see another car on that dyno. I think the brakes were on.

what dyno?

A lot of people shoot themselves when they get on a brake eddy dyno for the first time...

like mustang/dynodynamics.

Lol. You arent being a dick. I have seen the same thing. Ive seen T25's make more power than this!!! Seen T28's close to 350. Not only is the sniff box broken, but the Dyno has to be messed up too.

Not the most scientific comparison but I raced R33GTS-T three times. I was only on my Enthalpy tune, NO SAFC, NO cams, and only 10psi. We were DEAD even. He has a RB25DET that made 301 whp. So how with 5 more psi and a tune do I make 277? Or am I crazy. Im gonna see if I can get the charts on here...

j20accord00 · 09-07-2007, 07:37 AM

lol yeah it was late and i kinda felt that maybe you would have taken me the wrong way lol but anyways man..i really wanna see what kinda power ur car is suppose to put down with them kinda mods. we seem to have a few things in common (setup wise) and like i said i should be done by the end of this month. so im looking foward as well. anyways. u should try to find a new place with a better dyno. i got this place that jus got put up its like literally 2-3 mins from my house but its also a mustang dyno but whatever. keep in touch man talk to you later

OBEEWON · 09-07-2007, 10:58 AM

Dyno Jet, and they read high supposedly.

number80 · 01-23-2008, 09:01 PM

These setups are so simple but yet so efficient.

Slightly off topic but what clutch do you guys run with these 350-400 hp setups? I'm interested in a smooth and not so harsh engagement one that can handle that much hp/torque.

garagelu · 01-23-2008, 09:05 PM

Wow this is such an old thread and overdiscussed. The clutch I have and love is dxdracingclutches.com. The engagement is like stock and will hold 450-500 horse.

number80 · 01-23-2008, 09:08 PM

Ooops I did a search and didn't see the date. However an over discuss thead is a good thread IMO.

((sr)) kelly · 01-23-2008, 09:15 PM

im getting my car tuned next thursday... ill post the numbers

sr20det
2871r .86
hks step 2 264 cams
hks dual rated springs
nismo 740cc
greddy fmic
apexi pfc
hks evc6
255 lph
z32 maf
apexi SS filter
3.3 inch catback
3 inch outlet and dp
Greddy intake mani
Vibrant tubular exhaust mani
no a/c
ARP studs
apexi metal HG
Z32 fuel filter

hoping to hit 400 whp with 20 psi, and bumping the rev limiter to 8k

DrifterProdigy85 · 01-23-2008, 09:53 PM

Yea i did 353whp on 93 octane pretty easily. Also clutch i use is a Exedy Stage II. Its a little harsh on engagement but very drivable. ACT Extreme Street/Strip would probably be pretty nice.

OBEEWON · 01-31-2008, 09:06 PM

Who wants my .86? Im going 30r

s13envy · 02-07-2008, 07:41 AM

can't believe this thread is still going on lol. I guess I'll update on my car. I got the sc61, BC 272 cams, 810cc injectors, new tune, ect put on. Had problems with it for about a month (thought it was the tune). turns out that megan FPR's are inaccurate as hell. It was running lean at 60psi of FP. put my stock fp back on and ran perfect afr's. Still had some slight problems with the way it was running. driving home from a friends, car dies and wont start back up. Turns out one of the comp cam valve springs broke on me, bent a valve and dinged a piston. So now I'm looking to fully build my block and 600hp

Also turns out that BC cams require cam gears due to being degreed wrong or whatever causing low compression numbers. I only had 90psi of compression across the 4. My friend had the same problem, bought cam gears, degreed the cams and got all his compression back. So a heads up guys using BC cams!!!!

Are you seriouse? Is it only the 272's? This would explain a whole lot. How did you come to this conclusion??
How did this affect your A/F's before the gears?

jobestudios · 02-10-2008, 11:50 PM

Looking for some insight as to what to expect with my setup.

Stock S14 SR20DET (stock manifolds, stock head, stock block) (zenki)
GT2871r .64
Apexi Power FC w/ Commander
740cc Injectors
300zx maf
Apexi Power suction air filter with 3" intake piping
2.5" charge piping on a Vmount intercooler with 18x11x3 core size
Apexi AVCR set at 18 psi
3" turbo-back straight pipe
255 walbro

Think I can clear 350whp? I haven't seen too many people with 2871r on a s14 sr post up?

I know venom injectors aren't the greatest, but should I even consider running them temporarily until I can source some better ones?

jspaeth · 02-11-2008, 08:06 PM

Just swapped in a 2871R....no real engine mods, except for 740ccs, greddy divided turbo outlet, greddy rspl front mount, etc.

Made 305 ft-lbs and 318 hp at 17 psi.....tuned pretty conservatively by Jeff Evans in PA.....He said cams should add another 40-50 hp no problem. Power band feels great.

Like codyace has said, flooring in 1st and 2nd is almost useless...even from a dig in 2nd, flooring it results in traction problems, sometime in 3rd too!

What shop is Jeff Evans affiliated with? Also what engine management are you using?

jspaeth · 02-12-2008, 07:50 AM

Jeff Evans is owner of Evans Tuning.....word on the street is that he is one of the top tuners in the entire country....has tuned 1000's of cars, including FullRace shop car, president of Apex's car, etc.

I am running PFC D-Jetro....god it is so nice to not have a MAF....the response is so much better and the car runs way smoother

Brian W. · 02-12-2008, 10:26 AM

keep in mind his is on a DYNO DYNAMICS Dyno...

BC Stage 3 cams
stock head w/ ma-motorsports solid lash kit
20 psi
gt2871R .86
Greddy intake plenum
PFC Djet
Tomei 740cc

dont mind the spike, the boost controller wigged out on this run....

Did you have any problems with the Crower Stage 3 cams? That number seems a little low.
