[240man91]

ok i have a ka24det with a t25 ok well i just got it done an when it gose in to boost it spudders an pops but only at like half to wot what dose this mean it is rom tuned an has 370cc injectors an a tuned ecu an a avcr boost controler. with fmic wyhat u guy think

[s13drifter88]

didnt the timing retard fix this earlier???

[240man91]

yea it did this is from the other day posted it cause u didnt text back it had been a day an no answere just tryn to get info from otheres think u were bussy lol

[s13drifter88]

oh ok

[neverlift]

wideband?
more general info on your setup would be nice.. like if your running 10psi on a t25 setup its probably about maxing your 370s and making some real heat(which would make sense if retarding timing helped)...

[240man91]

hey guys when i let off gas an blow off vale gose off its putn some of the air back thro the turbo an i have tryed all the vacum lines none of the make thr bov stay open any longer whats up with that is it post to do this

[airman86]

which blow off valve? and how do you know it's going back into the turbo?

[s13drifter88]

a bov cannot eliminate all surge. it reduces the harmful effects of it but it doesnt relieve all of it. you the bov port would have to be the same size as the I/C pipeing to eliminate all of it.

[240man91]

ok so its not going to hurt it an it only dose it in the low psi like normal driving shifting round 3-4k i i know the bov is not adjustable its the new type of hks ssqv bov sux ik lol

[240man91]

hey guys quick thing he 89 90 240sx trans has a diffrent throw out bering right c i have a 89 or 90 trans in my car it has a long throw out bering in it an i have one for the 91 trans so i know they r diffrent but is it just the 89 or is it bith 89 an 90 c need to know i am getn a stage 3 clutch stock wont hold 10 psi at all lol

[s13drifter88]

idk about the throw outs. I always used KA-DE parts when I still had my KA

[240man91]

yea well i mean the trans in the same from the e to de it the throw out thats not i thinkj i am going to c if i can change the controll arm for the throw outs an put the de throw out in my trans i dont see y the changed them lol an i caint find s*** on the web about this eather

[240man91]

hey i got it stright man the fly wheels r the same an the pressure plate is just a bit diffrent so if u have a 89- 90 trans in a 91 or up just run a 89-90 clutch system the disk is the same to just the release berring an pressure plate r diffrent the pressure plates r only but a 1/4 diffrent witch will make it slip a bit cause the releasr berring wont let it close all the way just a heads up i got a stage 3 clutch ordered from f1 racing its a puck 6 disk should b more than enouf to hold what i have i have been lookn at some light weight fly wheels do they make that much diffrents have any of u ran one

[240man91]

hey man i found a r33 close to me for 1500 has 105k on motor an trans think it would fit in my 240sx

[s13drifter88]

yeah with the mckinney or top hat mount kits and some wiring and a little hammering out the firewall. very potent swap tho.

[240man91]

yea it would b sick in the 240 real quick but parts for those motors r high lol

idk about the throw outs. I always used KA-DE parts when I still had my KA

Off topic question for ya. How was the change from KAT to CA?

[s13drifter88]

i love the revs and the feel of the front end now with a little bit lighter engine and how it sits a little farther back. the front doesnt feel as sloppy just by shedding somewhere around 100lbs i think and it being moved back over the crossmember. also theres more room under the hood which is nice as far as working in there. Power wise Ive been very pleased as well, its very fun to drive and runs very smoothly, even at high rpm. The KA always felt to me like it was balanced on a bathroom scale. i have severe nerve damage in my right hand and any vibration drives me painfully INSANE so Im prob being over critical tho but thats my $.02

Are you considering a CA or something???

[240man91]

thats true with the ka-t car vibrats alot mor than it used to

[s13drifter88]

its not a matter or ka or ka-t, they both run and idle the same. the CA just has a better balanced crankshaft and you feel less engine vibration in the car while its running. I remember I had to have my ecu repaired cause my maf wiring melted on the manifold and it fried a ribbon trace in the ecu. well after I had it fixed my rev limiter was not 7500 anymore lol. i was drifting with some friends and my car was taching out like a b*tch! I set my safc to record max values, i was revving to 9,300rpm and it was as smooth as glass! scary... but smooth. i never did anything about it, i just revved it to 9k when drifting. it was almost like my gears became endless lol

[240man91]

nice idk but my dash makes noise an s*** now that its turbo the turbo is fine only dose it at like 5-6k not bad but still dont want to here it lol

[240man91]

hey what u guys think of my hood i did it my shelf

[WDRacing]

Are you considering a CA or something???

Definitely not. I don't think I could ever put a smaller motor in something. I was just wondering how it compared to the KA.

[s13drifter88]

I like it. They both have their pro's and con's but if I were doing it all over again Id still pick the CA. Its a little anemic down low but after about 3500 its awesome. Even stock with a red top t25 it ripped and I loved the revs sooooooooo much. It just wanted to be beaten so bad and the harder I pushed it the more it delivered every time. What I do miss about my KA is being able to go to Nissan or Oreily's and get anything I need and I also miss my A/C. The compressor was seized with my CA swap. I love the KA's punchy torque tho.

[240man91]

never rode in a ca car but i can say the ka dose have torque lol

[s13drifter88]

the CA almost reminds me of a rotary but with more torque and no doritos. its scary where they can rev to. almost lack of atmosphere revs

[240man91]

thats cool i have had two rx7s one bulit an one not an yea the one i bult would rev to 9.5k easy u can c the other one in the back ground if u look lol but i love rx7 they r fun to drive hard cause they seem to like it

[s13drifter88]

hows the car man

[240man91]

running strong killn hondas left an right an mustangs are out of sight lol. but yea it runs real good i am geting 26-28mpg to on hwy thanks for all the help man it would have took a long tiime with out your help lol. hey i got mine done befor my buddys sr got done he is just now getn it done an he started his last year lol. now its time to c witch is faster. stock sr or stock ka with sr parts. i think ka at ten pounds will take the sr down he has all the same stuff i have but just on a sr same boost controller an ex is bout the same to both 3in except mine has a hi flow cat his is just stright pipe. i think i will win i will let u know how it turns out o an his sr is in a 91 hatch just like my car.
