Ideling problem on 511whp Sr20.

[jgreen956]

New to this site. Hello to all

Just wondering because i bought a s13 with a 511whp sr20 but sometimes when i turn it on and let it warm up. I will rev it and its set to stay at 1000rpm..But when i rev it, it will go below one...it wont die but it goes below to like 700rpm..Is that normal?

Also my battery runs out of life fast. I have to use jumper cables to turn it on. Could it be i need a newer battery. Because what sucks is that i have a small battery for all the mods my engine gots. But really dont want to re locate it to the back. Is there any other small batterys that are really good?

Thanks to everybody

If its a cold start up, its normal that it will idle high. As so as the motor starts warming up, the idle will drop. As for your battery, its needs to be replaced. I run a Braile battery, look into them.

setup looks a little ghetto with the muffler piping and all. Id say the cams would have a majority of issue with idle. If the car isnt tuned correctly with the right amount of fuel and timing for the cams it will want to die. if its idling low sounds like it needs a little more timing.

Your FPR isn't connected either.

look at his hot pipe, it look like a piece of aluminized steel exhaust pipe, CRUSH bent( by an exhaust bender, not mandrel bent aluminum) to fit....= Ghetto, and i believe Topspeed is a ghetto knockoff of the Greddy intake mani, and why do you not have a way to regulate your fuel pressure? aftermarket rail, ss lines, STOCK pressure reg??? go get a Fuel Lab reg, or an Aeromotive, then have t re-tuned on a proper fuel pressure

Yawn

Please dont come on here acting like Johnny Hard a** when you cant even open your eyes. Yes it has good parts on it = A but execution of install = D.

[j_rocc2003]

yea just sounds like it is warming up. is the tune set up for it to stay @ 1k?? is there any performance loss?

[DrifterProdigy85]

My SR has a similar issue. On cold starts the rpms drop to 500rpm and wants to stall out untill the engine warms up then it settles at a smooth 900rpm idle. I usually just hold the revs above 1000rpm untill its warmed up and then it idles fine. Im unsure if its the tune or ive heard its the IACV.

[Sileighty_85]

Adjust IACVCheck for boost leaksCheck CTS

Its normal for the SR to idle kinda high at start up/ being cold its in warm up mode.

My husbands does it when he starts up his when its cold.

Im confused on how that FPR is being used...the return line is on the bottom of the FPR, it looks like it being used to "cap off" a port?

How does it drive over all? is it just an idle problem?

AS for the battery get it tested and look for shorts in the system/check the charging system.

[DrifterProdigy85]

Mine drives perfect once its warmed up. Zero boost leaks and ive tried adjusting the IACV but doesnt do anything. Im almost thinking it could be bad. Is there any real way of checking if the IACV is working proper?

[jgreen956]

I have a a1000 fuel pump. Regulator and everything. Everything set up and tuned proffesionaly by nissan proffesionals. I spent about 22 grand on the motor and car fixing it. Found out that the battery was messed up. Only thing is that the battery I have..I got to special order since the size is very small. Looks like a damn lawn and garden battery lol but it's for cars. Was having troubl starting car. Battery was the whole problem..weird but yea...thanks for the help everybody even though there is some jealous haters!! Also there was a vacume leak that I fixed. Runs solidddddddd

[DrifterProdigy85]

It takes a well running setup to do over 500whp. I would be kinda mad though with your "nissan professionals". They need to do a cleaner build. I did mine myself in my garage.

[DrifterProdigy85]

For the battery, just get a Optima Redtop and relocate it to the trunk. Never have to worry about cranking problems again.

Mine is identical to prodigy's. It idles perfect after it warms up. It's funny to me how people get on here and call other SR owners setups ghetto even when they're making 500+whp??? Who cares if it works!!! I;ve got a desiel turbo, ford MAF, msd injectors, and a $8K motor ina $2500 car. If we could afford it we would all be on the 911TT forums not this one. We all like these cars because of what they are capable of FOR THE MONEY!!!!!

[DrifterProdigy85]

Haha i know what you mean. I paid $300 for my chasis and its a Mazworx 2.0L Race Block and Head. $15k engine build in a $300 car. Thats called Dedication or Stupidity, i cant remember which. lol.

[jgreen956]

Yea maybe u can come down to Laredo to clean my engine up lol yours look sick bro!!! But yea man for the people who coMplain... If it works. Why not.. Save some bucksss. THats what I did and I had alot more cash to spend on more things. Stop hating, learn and be smart! Anybody can have a greddy intake mani. But when people see myn it's custom made so people freak out and love it

[DrifterProdigy85]

Thanks man. How much boost and what gas did it take to make 511whp on your 30R? Mines doing 502whp on 93 octane and 21psi but its a T67 and im still MAF Tuned Ecu.

[jgreen956]

It runs on 93 octane and boost I'm pushing like 17 pounds.( might boost it up more to like 27 pounds lol) On c16 racing fuel I'm getting like 520hp.

Yawn

OOOOOooooo

[jgreen956]

The fpr don't need to be connected. I got my ways . Trust me everything was done. I running 10.4 a 1/4 mile on pump gas.... 9.8 1/4 mile on c16 racing fuel.

[DrifterProdigy85]

Hes running an Aeromotive or other regulator. The regulator you see on the rail is just there to block a hole. Post up more pics of the car, dyno sheets, and time slips. 500whp wont run 9's and the GT30R wont do 500whp on 93 octane.

[Logan76]

500whp wont run 9's and the GT30R wont do 500whp on 93 octane.

That's what I was thinking.

[jgreen956]

That's your opinion, I got alot more mods under my hood that are not being listed. I will take pictures when I get my car back. Getting it painted. I'll keep u updated

[DrifterProdigy85]

In the mean time post up the Dyno Graphs and Time Slips.

LMAO this thread just went to the BS league. If you really spent 22K as you claim Id kind want more than just 500whp... lmao wtf. Also 9s on 500whp. Only cars ive seen that do is a gutted RX7(making 589 whp) and a 1600 pound Datsun. Let me guess your doing this on coil over suspension with street tires? And magical unicorns fly out of your a** when you hit the gas?

Also what other mods matter if your making 520 on 27 PSI! You got an after market switch that makes 520 feel like 10000000 whp?

One last thing go tel the nissan expert thanks for using exhaust piping for your inter cooler... He couldn't splurge another 100 bucks for some nice aluminum piping? Something that transmits heat much more efficiently... and saves weight.

[playero_loko]

So i guess your ride looks so much better than this huh?! funny how it seems everyone but a couple of people havent been picking on his car!!! i guess everyone else car looks like a show car around here...

Well I'll say this, I want to see the dyno where he made that power on pump, if he shows it ill give him a damn cookie.

LOL that was funny man LOL

[jgreen956]

ok but i want two cookies ...I'll show u dyno slips F*** boys!! I love how haters tell people how there car runs like they own it or something. I just love that . I love how they can just tell u something about your own motor when they have never seen it run or had the car. Haterssssss. Yall haters are useless to this forum . Yall are the reason some forums turn it to crap. Help people in need . That's what we are suppose to do. If u wanna argue and talk crap get off this badass forum. Always hating and telling people what there car gots. Yall make it seem that yall got jets and sh*t..I'm just like yall trying to do the best to my car. Don't hate, start appreciating hard work .I'm sure there's alot of helpful people here but damn there is too many haters. Grow up and stop acting like children.

Thanks to all the helpful people on this topic. Thanks for having a good word and great comments. Yall are the Sh*t!!! Lol Keep it up!
