bog on acceleration

[Focker420]

I have had this problem for a while and i can't figure it out for the life of me. I got the rough bogg on acceleration it happens only under 4000 rpm and only occasionaly i have done a vacume test and noticed i have low vacume at idle but picks up to normal when revd up. Also i got a rich running code.

Any info would be awsome

Fast Non-turbo would it compare to a tsi but both same size turbos

Umm, what do you mean by the seccond part of this post? The fast N/T thing. I mean, my N/T 4g63 is the fastest I've seen in a while and I keep up with slightly modded TSi's/GST's (etc.) no problem . But umm good luck, maybe the chugging is from a bad cat? It dosent do it above 4000 RPMS? Someone help him.

Please use a better title for your thread next time - "dsm wiseman help PLEASE" doesn't tell anyone what the problem is and you're less likely to get help. The title of your thread should give everyone a hint of what the problem is you're having.

I've edited your thread title to be more descriptive.

does your car sometimes die when comming to a stop?

 

[Focker420]

ya sorry about the topic title but tryed to elaborate on some other related topic's but got no replys for like 4 days so had to say somthin to get some attention.

So my problem is that at idle my car is choppy and jumps around from 600 to 1150 rpm and sounds like a V8. Say the light tuns green start drivin and just ingauged the friction point start movin and bogs under 2500 -3000 rpm i accelerate more to pick up rpm and goes fine. Also happens on down shifts pickin up speed say around a corner.

Car doesn't stall or die but like i said choppy idle drops to low rpm and then compinsates.

About the second part i got the 420a motor and want to know if i get, say a stage 4 turbo and do all the internals would i be able to compete with a tsi with the all-wheel drive. Sure u get alot more traction, but. If your a good driver and can keep from burning too much rubber u would get more power to the front wheels and mabey faster power to wheels. because the origional whp would not have to turn all the wheels just 2, also not divide between 4 wheels?.

anyway i have access to all testing tools because i work at a dealership so if u got some diagnosis thats would tell me whats up would help alot. i replaced the 02 sensor have no cat 2 reisnators and have checked the vaccum which is low at idle but is fine at higher rpm, also i checked my fuel pressure which my journey man said was fine 60psi or somthin can't remember right now. The idle problem could be from the cams i put in still waitn for my aem 5 bolt timing gears too.

thanks lots.

As for the 420a with a 'stage 4 turbo' yes you can build it up to beat a TSi, but honestly I just see no point in fully building it with turbo etc., You'd be better off buying a TSi in the first place, becasue with very few mods to a 4g63turbo, you can make 275+HP, which is nice for how much money you DONT spend! But hey, if you can afford it, I know that turboing a 420a is relativly simple, and yes its all about the driving, someone with a FWD that can launch good with minimal spin, can take someone in an AWD. If you look up some stock 0-60/0-100 times for Talons/Eclipse, you can see that the TSi FWD had the exact 0-60 time as the TSi AWD...but it's all about how well you can drive it...simple. Good Luck bro.

Thats pretty much what i thought it has been pretty expensive so far and didn't think it would be cheep but i've gone to far in my mind with upgrades to turn around and sell the car just to buy the tsi from the start. So i will make this n/t stupid fast or will try with the funds avaliable.

Got a liittle off track i stiil don't know what to do about the bog/ chugg.
anything, some ideas mabey?

 

[black93es]

I really can't help you out much the 420a is a sketchy motor sometimes, and I don't have too too much experiance with them breaking down. I mean do you think you could possibly get it to a near by shop to a diagnostics, and then come back with what your mechanic says. Don't be waiting for an answer on here.

 

[Focker420]

ya sounds like a good idea but it has alredy been done i have taken to mitsu dealership and they were no help they said get rid of your msd ignion coil car works only on oem ngk plugs and wires and oem coil pack.
personally i think the service advisor is a complete idiot and makes me mad just talkin to him and so i took it to the chrysler dealership and they came up with only ideas and wanted me to keep payin them to be part swappers. screw that i was hopin somone had a non turbo with some experiance that would tell me what mod im missing to have it bogg and chugg from lack of somthing. my car did a crazzy stumble when i started it and for some reason cleared my engine light still not runnin right tho and light has done this befor. so wow if i can't figure this out im going to blow the PEICE OF SHIT CAR UP.
im on my last legs with this. My buddie just got his h22 put into a 92 accord and this freakin halls ass. the vetc is got really strong high end rpm gain and he can wrap around the tac to like 8500. WOW bag it much, hes havein fun tho.

Any way losein hope and about to light the fuse on the car bomb HELP!!

 

[Focker420]

Ok so i might have got a little outta hand there was haveing a bad day but an update to the bog. I was doin the routine checks and noticed my plug wires were breaking down the rubber and there was rubber residue on the plugs so i change the pulgs stuck with ngk plugs but couldn't get ngk wires so i switched it up and got the msd wires to go with my coil pack and the bog has almost disapeared but is much better. There is a name for the rubber breakin down and it makes the spark plugs arch but only once under load...

so ya is almost 100% again gotta smooth out that idle still.

 

[black93es]

Good for you man. So theres just a little bit of chug now since you swapped out your wires? That's sweet. Good luck, and maybe try re-gapping your spark plugs to get rid of the rest of the chuggity chug! haha. Have fun and please don't blow ## poor Talon! Give it to me first, I'll put a D15 Civic motor in it...haha the VTEC-E model tho (VTEC-Economy) all those 91 horses under the hood of a 2G Talon...TOO FAST! HAHA J/K. Peace.

 

[black93es]

Oh and too comment on your buddys H22 swap...H22's f*ckin rip. I've driven a turbo H22...almost made me go to the dark side...and those K20's w/ turbo..holy shit. fastness, not all honda motors are slow...people don't realize their potential...

 

[Focker420]

ya so about the coment of givein u my talon. first the gold diggen biatch will die by my hands first be for u touch it and the wires were mostly the problem caused by CARBON TRACKING were the wires had traces of carbon (looks like black resin on the inside of the wires and on the white part of the spark plug) I kinda hate the honda engines they go to freakin fast for havin just a vetc. Whould that be the same as adjustable timing gears? They both just advance or retard the timing.I want to beable to smoke any honda and i hate srt4's even more.

 

[black93es]

No, first off its not "vetc" I dont know if this was a type-o but I saw you did it more then once. I dont care, I am just a lil' obsessive compulsive, haha. Anyways, VTEC means Variable-Timing & lift, Electronically Controlled...and VTEC is very underestimated. And yeah, its f*ckin scary how the DOHC VTEC motors dominate. Usually when people talk about "hatin Hondas" or whatever, their mainly thinking about the ghey ass SOHC Civic EX's with the "VTEC" but its a totally differant working mechanism than the DOHC VTEC engines. So yeah, the DOHC VTEC motors are sick in my personal opinion: check em out some time for kicks when your bored: K20 (Acura RSX) B16b (newer Civic Si's) B18C5(Acura Integra Type-R) B18C1 (GSR Integra) B20VTEC (CR-V).....theres alot more, but those are the basics. Ghey I know, but you gutta know what you battle before hand so you don't make yourself look silly, we just cant have people in Honda's beating our DSM's. Just not an option. HAHA, well your cars not exacly a DSM, but who cares. Peace, ask more Q's if you have any...IAM RICK JAMES B1TCH!

K my bad for the spelling error I'm a mechanic = bad speller and it probably doesn't help that i smoke alto of weed bad for the short term memory. I'm a second year apprentice anyways.

So do u got any good ideas for mods that i should do, I would get smoked by my Buddie accord with the h22, he took me for a rip. I can tell , too ashamed to race and lose cause i can see the outcome already.He crashed his car and its pretty much been paid by his old man.pisses me off doesn't have the appreciation.

But I'm trying do do all the mods i need to before i get the whole turbo setup. But i don't want to have to back-step such as the headman header i have to ditch when i get the turbo.

So i ya got some good ideas let-em rip.

 

[black93es]

Yeah, I got that lil' w33d problem to. Emmm, b0ngs! haha, well anyways, I am not gunna sit here and lie to you, you will get beat by the H22 , especialy if he has a few bolt ons, they make 200+ HP with small bult-on's. Not bad for N/T, considering I must've spent $4000+ on my engine internals/bolt-on's/clutch's etc. etc etc. But yeah, my opinion is build up your N/T 420a FIRST, and then put the turbo kit on, of course, after you've run your internal mods and bolt-on's for about a month or so (assuming you drive it everyday) Honestly, it's not too late to look into the 4G63T swap for your car. I am estimating it's a $2700.00 swap, becasue the motor mounts and harnesses dont match up. I bet you don't care, probably more than you spent on the car, so for your 420a turbo project, I am saying build up the motor first, so it's capable to run boost to it, without frying everything. Look heavily on internal mods. you'll NEED and I stress need, a multi-layer steal head gasket (boostin over 6psi will probably total that 420a head gasket, fast) lower compression pistons will be needed probably. Stock TSi's have a signifigant lower compression ratio rather than the N/T 4G63, but some people argue that high compression pistons work good also, I agree, pistons wont matter as long as there good quality and forged. Also look into coil packs, wires, plugs etc. for better combustion (MSD=big helper) FUEL FUEL FUEL! You need to upgrade your damn fuel system (pump, lines etc.) that will be the first to go your fuel pump, look into adjustable cam gears and stronger cams. double valves, and titanium reatainers etc. make a big differance. As for engine breathing, a full exaust with no cat, or a cat eliminater (test pipe) with ceramic turbo headers and a new intake manifold (sheet metal intake manifolds are nice) well, I am not gunna go on and on about what you need to do to get ready for the turbo (you probably have a good idea of what you need) but I am saying, build up the motor FIRST and work on those weak lil' internals. Well, for more info. just do a Google search for 'turbocharging the 420a' If you have more questions ask, I check this crap daily. BTW, how's your Talon been running? Peace.
