S14 SR20det still stalls after BOV Recirculation

[98s14inaz]

i didn't have time to read the whole thread but your symptoms sound alot like mine. Do you have a catch can or anything like that running off the valve cover? If you do make sure you aren't creating a vacuum leak there. At least that was the problem on my car that I just got.

[motoman399]

remedy? wtf i'm TRYING to make my car backfire lmao

try retarding the timing a few degrees. and maybe hallow out your cat lol. or unplug the rear O2 sensor lol. start getting creative.

[J14cm7]

No catch can and no vacuum leaks. Vacuum is consistent. I think i just have to bring the IACV out a little more.

Lol you guys are crazy. Now this thread has turned into the "how to make my car backfire" thread. but yea if you want it to run rich those are some ways to do it. definatly wouldn't make your engine last longer that's for sure.

haha damn right!

KA24DE FTW!!!!!!

KA24DE FTW!!!!!!

Moto i was feeling everything you said up untill that point. Unbuilt KA...get the f*** out of here.

[motoman399]

who said my engine isnt built? lol its not but it will be fully ported and polished pretty soon with a fat top mount snail haha.

You need stronger internals bro then ill approve

[motoman399]

You need stronger internals bro then ill approve

wait you have a stock turbo..... and less displacement and you have crystal headlights

the list goes on lol. jk jk

[J14cm7]

Yea well ill give you a ride when your KA blows up and my RELIABLE sr is still running strong

ask spooled how often he blew up his ka-t. lol im just a hater thats all.

^ lol i cracked ringlands on #4 due to a bad walbro fuel pump, sucker couldn't even sustain over 20 psi. After I replaced #4, I'm running a daily 8 psi on the same setup puttin down about 240whp..I love ka-t's, cruising around at 1800 rpms getting 30 mpg and spooling fat turbo's like nothing haha But other than that I was putting down 260rwhp/270tq on a bone stock ka24de with a t3/t4 turbo, pulling on evo's and sti's for over 2 years and driving about 300+ miles a week.

here's my dyno pull puttin down 268 whp and 283 tq on 11 psi, car was a beast at this boost level...8 psi feels weeaak, but it's good for daily

but anyway, back to backfiring lol I have a test pipe and 3 inch exhaust and no fire =/ just some snaps, crackles and pops

I appologize for stating it incorrectly. back "fire" is not the term i should have used. It just pops everytime i decel under power.

I lik KA-Ts as well and if i were going to build an engine, meaning new stronger internals, i would go that route. but i run mine at about 14psi and for an sr thats fine but for a KA thats risky. Seen KAs blowup when you start betting past 11

damn forgot you blew your ring land lol. f*** me.

oh well that was impressive for 2 years.

its weird you cant make it bang flames out the back. i could just do like 7-8 2nd gear pulls on the highway and then start romping on the throttle free revving it and blow them. it was like flames on demand. i had a 95 ecu, maybe that helped?

ya but stock block wise. if you had like a t3 on a sr and the same t3 on a ka, the ka is going to win in the power/torque area if they both have a good tune. and its only because of the displacement. at least thats how i understand it. im sure someone is going to tell me how it actually is lol

[J14cm7]

I compltetly agree with you but i am more worried about reliability than power. If it means going slower and being reliable ill do it everytime. besides with a T3/T4 your gonna have more turbo lag. The T28 is great. the lag is almost non exsistant. I do want to go KA-T someday though but probably will never be able to afford it. I gotta finish up this money pit i have now haha

[motoman399]

ya but the lag isnt that bad. at least on mine. i have a t04b, the on center turbine housing. and i have it ported and polished so it spools pretty quick. probably not as fast as the t28, but it is very fun. it wouldnt be hard for you to go ka-t. you already have the turbo, and piping and ic. all you would need is tuning and injectors and manifold. but im sure thats another project. maybe you can do one for just race. i plan to run about 14 or so psi. basically what ever it take to make about 320whp. and i have a spare engine if i need it. one nice thing about the ka is if i need a head gasket or what ever i can go down to the auto parts store and get it lol.

i just auto crossed my friends rb25 s14... SO SICK! he has a gt35r twin scroll ball bearing turbo with a full race mani with twin 44mm wastegates. and greddy manifold. and thats only the engine, he has so much into the car. its amazing to rail. that car was an animal. and i suck at auto cross. lol need less drifting. haha

[J14cm7]

Yea I am happy with the sr for now. its got plenty of power for how the car is built for now. I might pick up a spare KA block in the future and build it from the ground up or just say F it and get a 2jz and be broke the rest of my life. I have started coilover shopping cause i need to get something before auto-x season starts on april 25th. PBR or stance...

PS this thread has just gone to s*** lol

you know i drove my buddys s13 sr a few weeks ago. it was the first time i drove an sr. it wasnt bad. i dont hate the engine, i hate the fact that the ka's are so boost friendly and people ditch them so easily because they dont have the knowledge to turbo a N/A engine. dont do a 2jz. the rb's are so nice and in the family. leave the jz's for the toyota's lol. +1 for wanting to build a Nasty KA

PS this thread has just gone to s*** lol

FTW!!!

[spooled240]

^I LOVE the fact that people disregard the ka's, gives me good deals on spare parts unfortnunately that's not the case anymore...you are beginning to see a full ka24de w/ trans and wiring harness for close to 800-1000 bucks rb20 swaps go for about a grand

it depends on what turbo, 14 psi on a t2 wouldn't be too bad, 14 psi on a t3/t4 put me around 300rwhp but I wouldn't wanna push it at that hp for a daily driven car even though I think it could handle it.

and the lag is actually not too bad, the bigger displacement helps. I can spool about 4-5 psi at 2,000 rpms and get some good low end tq but the actual power band starts at around 3K rpms.
