boosted ls once made 325 hp, needs help

my freidn bought a 90 civic hatch with a 325 ls engine, built internals, boosted 12 psi. etc. anyway. that was a whileago that the car had been like that. nowadays it feels like its only 200. his cams are at o degrees. and he doesnt believe me that we should retard his timing like 3 degrees. he saying that he just going to wait to get it "tuned prperly" now ive never had my car tuned or anything. but from basic understanding. they adjsut the cams and mess around with the fuel flow rates in the ecu. what else is done in the turnign process. and should he let me retard his timing 3 degrees?

they dont mess with cam timing to retard. its distributor timing thats messed with electronically not phyically.

if he never messed with the fuel or the timing and ran 12psi. his motor is toast. tell him to do a compression check

his car was dyno tuned to 325 hp, i bet the fuel and timing was tuned with that. now, i dont know waht had happened but his car became untuned, his rev limiter is not at 5500, and like i said it only feels like 200 hp, but hes been beating on it, hes raced a vette. i didnt see it, but with a limiter of 5500 i doubt the turbo and shit really would help him beat a vette. and i know he beat a sebring. so i dont know.

toast for what

toast for what

for you to eat, what else. :screwy:

and to the original poster. you didnt give us alot of info. i mean you never even said if his car was tuned at all, or even specs on the motor. you cant even verify if it was tuned accordingly or not. and my car can beat a sebring so idk what to say about that. cars dont become untuned by themselves in a sense that the programmed fuel maps dont change. something with the motor must have changed, did he add any new parts to it ?

again i would recommend a compression check, post up results

all i know is that the motor has become untuned somehow, someone has fucked with it.
the engine is bored to about 19.5 literes (i think)
b20 crank
12 psi
internals
new 2600 lb clutch
im trying to find a pic of it, it could take a while

i dont need a pic, i need info on the motor. what kind of engine management does he have ? who tuned it?

one more time, do a compression check and post up the results

he doesnt know how to do a compression check on the engine, but he says it has uberdata on it. ill search for it

this kind of guy is the worst guy to have a turboed motor. he doesnt know anything about car and yet he has a complicated setup like that. no wonder he is having problems with his motor

"ive got it...hes running 87 octane"...no just kidding...i agree with civic killer...this guy should have his license revoked, a b20 with a 19.5 liter over bore....very very possible...have it towed to a shop...he prolly skipped a tooth on his timing belt, thats what happend 2 my civic(2teeth) and it wouldn't go past 6ooorpm, and be easy when u post..calm down and take your time with spelling...

k, so. im at his house, he engine will now not turn over. the engine does not start. you can hear the fuel pump engage and all that jazz, but nothing. he says it could be his battery. but his lights and evverything work fine. so he says best case scenario to jsut get his car running everyday is the alternator. worst case, cracked pistons, bent rods, no compression, etc.
person who built the car says rev limiter set to 8500
3rd gear tops at 5500, and it sputters
during normal driving you could smell the unburnt fuel.
boost controller does nothing. wastegate has a 12 pound spring

:uhoh: So your friend is reving an LS motor to 8500 rpms, it has a b20 crank, is bored out, and he's running 12psi of boost?
I'd say skip the compression test and just rip the head off of there to see the damage he's caused. Then rebuild the engine for the damage done, get a boost controller (even one of those really cheap ones), and run 6-7psi until it can be professionally tuned (because someone who doesn't know how to do a compression test should not be trying to tune a car themselves).

boost controller does nothing. wastegate has a 12 pound spring
boost controller does nothing...does that mean u opened it all they way and then beat the crap out of it?...j/k.....so it doesn't turn over....i thnk your buddy jsut blew his motor...especially if it ran like crap days before....

ok, the engine wont rev past 5500, its bored out to 1.95 liters. it has built internals, sleeved block, rods, pistons etc. he had a shop put in the boost controller. and no matter how low he turns it down. the boost guage always reads 12 psi. and u can definately feel the turbo. we think the battery just doesnt have enough power to make it turn over. apparently it can be turned on with a jump start. so we think it could be the alternator

so then get the alt tested

what boost controller are you using? for a boost controller to work, you cannot set it lower than the wastegate spring ;) the tuning was on a dyno. all part throttle, idle, and wot has been tuned?No postable datalog info? what are your AFRs and ignition timing? stop playing with the cam and timing if the uberdata was already previously tuned. if you can send me the datalog and bin file, i can probably help you out. your problem most likely lies in the tuning or the ecu. the thing is, no one knows what kind if of damage if any has already been done. if your still driving it around, then, keep your fingers crossed. pull your plugs. how do they look. a compression and leakdown is very important. im also curious, who is going to tune the uberdata for him? also how does going into boost look like (hesitate, bogs, pop, detonates)? hows the part throttle and idle looking? complete description of all fuel and timing modifications?

reading all the other post you have done, it is very concerning. your friend really just threw himself into something he has no comprehension of. if the motor is still fine, go tell your friend to learn a little more about uberdata and tuning before troubleshooting it and deciding to keep it. stop driving the car. if he's not willing to figure out whats going on with his uberdata, he should just get rid of the uberdata and go with a hondata S100b system and let someone else tune it for him.

YIKES and Good Luck.

dude superbluecivicisi, there is no way at all he is going to understand what you just wrote. and because he knows so little bit, i doubt he has any bin's of his tune. i think the only people that know what your talking about on here is like you, me, turboekhatch, boosted331.

im trying to help him out starting at step 1 of doing a compression check, but ive told him 3 times and he doesnt listen. and he still hasnt told me if he has changed anything on the motor because like i said tunes dont change, the motor changes

the engine wont start, how do we do a compression test then?
we dont have any way to get into the uberdata system.
a local import shop is going to do the tuning for him. i believe they are going to do wideband testing, if they can get the engine running or not.

civickiller,

yes, i know, but, if he really wanted to know and solve the problems, he will search or try to figure out what his setup is really about. or what the hell were even talking about.

i dont know who is tuning your uberdata system, but, its hard to find a good tuner. you can just drop the uberdata and grab a hondata S100b. it will simplify your problems and things you have to deal with.

the engine wont start, how do we do a compression test then?


does it crank at all ? because to do a compression test, you dont need it to start, you need to just crank hte engine. which is why when you do a compression test, you usually pull the ignition coil wire or the plugs to the dist to make sure it doesnt start

no crank at all

whatever you guys did to the setup in the beggining, put it back the way it was when you first bought it. your problem is going to be hard to diagnose online. hey civic_d16y5, where do you live?

also, heres a place to start with your uberdata issues.

heres a list of tuners.

omaha
we only had profeesions do shit to it. like a boost controller, finding oil leaks etc.

do you have a fully charged battery ?

he said it can be jumped, so when we do that, were going to run a compression text, to do that u have to take out all the spark plugs and wires, what about the fuel?

dont worry about it, its ok.

so did you ever test the alt?

check auto part stores or jegs for compression testers, summitracing has one for about $20 i think, but i dont knoe if come w/ the adapter that fits the engine. 2bl checkkk
