Just finished up the motor and....

[SlimTypeS]

Okay so i had just recently replaced my head as i had a few bent valves/bad valve seals... yada yada.

so i get it all put back together and did not fell like trying to mess with the timing so i took to a reputable place and had them do the timing job... replaced all the belts also.

The car starts up perfectly but... when you give it throttle its really laggy and doesnt want to climb rpms very fast... Also when you try and drive it almost wants to die out when your coming out of gears... and when you try to give it gas its really sluggish not to mention it doesnt want to build boost!

Wondering if anyone has any of these same problems? With some real help not some 2 cents

I have done numerous searches but no one seems to have my same problem with real answers so wondering if anyone has some helpful advice


Thanks Tim

Damn its been a very long time since I posted on this forum!!

Umm do you have a check engine light?
DSMlink? anyway to datalog a few runs?
Mods? Some more info would be cool.


Have you done a boost leak test?
Maybe you got a bad leak somwere, Might have over looked somthing
after putting the head back together.

 

[CHAR-FT]

How laggy is it, you shouldn't need a turbo to make it rev fast without a load. Does it seem to run ok? or is it sputtering really badly, just a thought, make sure the timing is right, some people do make honest mistakes, it happens. but also check for the boost leaks like they were already stated and check to make sure the spark plug wires are in the correct order, that's why I asked if it runs ok, you would for sure know if that's what the problem was.

 

[SlimTypeS]

Uhm... ok so i took a few things into consideration

1. The turbo is fine otherwise white smoke would pour out the exhaust...
2. It sputters pretty badly when you drive it and it backfire when you try to give it a lot of gas
3. i checked the spark plugs and replaced them (have not started the motor)
4. The map sensor was not "bolted" on but it was in the hole... (have not started the motor)
5. I am running open downpipe so i expect it to be a lil laggy down low but i know my car
6. gunna try out a boost leak test soon to double check... i know their is a leak in the throttlebody... but that has always been their during previous tests.. nothing big
7. Spark plug wires are fer sure connected properly as my car would barely even idle with the mout of order
8. I do not have dsm link i have some old school Efi systems inc. ecu my dad had it installed Awhile ago should not be the problem as i have never touched the map on it.... Never gave me a problem b4

Let me know some more ideas from what i have told you so far...

My mods are Intake 3" dp hahnracecraft evo 16g turbo boost controller turbo timer greddy intercooler piping and front mount pretty much the basic bolt-ons

Btw no check engine light comes on...

This one dude scared me telling me that my crank was walking z but i dont think thats the problem... as i would fer sure have a check engine light

Also i just did a lil more research and remebered that i have a msd ignition sytem mounted under tha passengers feet up by the fire wall... could this very well cause the engine to break up and backfire...?

If so any clues as to how to fix or why my msd ignition system would go bad in the first place?

 

[IEdroStarI]

have you checked to see if maybe your throttle body is dirty or not working properly? id bolt that map sensor too just in case... try starting the motor with the new stuff you put on and see if its still doing the same thing

 

[dsm-freak]

the ignition box could have something to do with it. check the dails and what not and make shure they are adjusted right and check the hookup for it. the ignition timming could be off. retarded or advanced to much will cause the backfires and such. had alot of this happen when i was building mostly muscle cars.

Thanks for the input guys... i cant start her up right now as i am running open downpipe.. my neighbors wouldnt like me very much! Not that i care just dont feel like them bitching

But yes i wouldnt think a reputable shiop would #### up the timing... but everyone make mistakes... When i go to check out my ignition setup what exactly am i looking for?...

As i am running a bigger read looking box with a smaller box that says msd on it... i think i have pics klemme check

thats my ignition setup... if it helps any



Also heres my boost controller... all this shit is pretty old as my dad did all the mods abck when he owned the car... but hes too dumb to remeber how to mess with the car z. But does anyone know how to use this boost controller?... I have read over the manual many times and how to set it and shit but its read in bars instead of just plain ol boost z

Its HKS btw

 

[IEdroStarI]

isnt it as easy as turning boost up or down with buttons??? if it isnt then get rid of that crap!! just kidding... but looks like you got some wires you gotta clean up though

Haha no... this shit is old school but this is my weekend warrior car z... I also have a rsx type-s with a k24 in it... for my daily and i dont feel like dishing out 400+ for a boost controller!

But ya i would still like to get this bad boy up and running hard again.. has not seen boost in over a year z

 

[redyute1]

These are the syntoms of timing not done properly/timing is off.

 

[bluegs03]

hate to state the obvious but did you check the base timing? If not get a timing light and see what you find it should be at 5 degrees. Secondly make sure your shop did the timing correctly this is very hard to do right even if they are a good shop. What did the shop say when you told them about the studdering and general performance of the car? The wonderful thing about getting work done at a shop is that its THEIR fault if they did something wrong. aka didnt line the timing marks up right.

**edit** damn Red totally beat me by 1 min!

 

[frankenstein406]

if its electronic why just get a hallman mbc for a hundred and sell the hks?

 

[dsm-freak]

if its just a regular msd box and not one of those computer programed ones it should have little rotary dails on it. those are the settings for rev limit, retard, advance, check those to see if those are zeroed out then try from there.

 

[djalogik]

check you timing, it may have jumped a tooth

 

[90tsitalonfwd]

if you need help reading the boost controller 1bar=15psi

 

[90_GSX_DSM]

This one seems pretty obvious to me. Like most of these people said check the ignition and mechanical timing. The symptoms you are having are very similar to mine when my mechanical timing was off. Shops can make mistakes and i'de be willing to bet it's timing related. Check it and get back to us.

 

[snowborder714]

Actually, 1bar=14.5psi.

 

[SlimTypeS]

Okay, so i did a lil work this weekend... i checked and re-checked all of my clamps on the intercooler piping... changed my spark plugs... checked the gaskets on the throttlebody

Results are : No more timing/ignition problem... cars runs fine and idles fine

But! whenever i start to drive and shift 2nd gear and the car starts to see boost or higher rpms... its like the car starts to bog and putter... put it in nuetral and let it idle for a while...

I got on the highway and shifted 2nd but this time i puched it and boost shot to 17 psi and held... i let off and the car was puttering again...?

Any help with this.. i checked and tested the maf its fine... Could this be a bad map sensor? or something else?

 

[OverboostGSX]

It doesn't sound like you actually did a formal boost leak test on the car? Even rechecking clamps 100 times does not necessarily mean you did not miss a leak somewhere else. Good luck!

Ya i know.... My buddy has a tester but lacks to come let me use it z

I know saying a boost leak is the easy way out... and it could very well be the problem, But i have heard some other things that it could be also!

Any thoughts on the map sensor being bad?... which wuld explain the car running fine until it sees boost

 

[SlimTypeS]

Btw i just pulled of the throttlebody again to check if the gaskets were cracked for a boost leak... (they were fine) I also pulled the pcv valve and checked that gasket, its fine....

I guess im going to plug in my map sensor into my buddy's car and test it out

But im taking some advice on this problem... Dont forget that the car idles and runs fine until it sees boost

 

[usdrew]

so it idles and cruises around okay? just when you want it to haul ass, it misfires? if thats the case, id check a coil. when they go bad, they tend to misfire under load.

 

[boostedawd42]

No offense but you seem the be avoiding the help offered, we tell you all the possibilities and you still go on your own whim. Listen to us, boost leak test, check base timing, check the "MSD" and see if it has the knobs for timing, if so check and see if its set to zero. All of your symptoms seem like they have been answered by at least one post in here. So get out there and check what we told you.

I did... no the msd does not have knobs on it, i posted a picture of the setup... I did a boost leak test and their are No leaks, The timing is fine or else the car would not barely run.

I checked everything people gave me advice on, and either fixed or double checked all of them! One thing i have not checked as Usdrew stated maybe the ignition coil pack is bad... the one thats mounted on the intake manifold right?...

Btw the car runs fine when you keep it under 3,000 rpms and out of boost, as soon as you try to get up in rpms not even punching it just easing into the rpms just to get up speed it falls on its face and wants to die out! I've exhausted a lot of possiblities and have torn down my engine and parts soooo many times to double check everything its getting to the point where i just want to give up

Btw the check engine light is clear until the car starts to die out after trying to bring it up high in the rpms if that helps out any

 

[boostedawd42]

So within the last 4 hours you got a tester and did a boost leak test, you failed to mention that point. You did post a picture of your ignition but that just shows the color, it doesnt show where it leads or the side, you say it has no knobs or screws, I believe you. Also you didn't check to see your base timing is correct with a timing light. You mentioned you checked some gaskets and the puttering/timing issue went away, but without actually touching the timing how could it of gone away. DSM's are very different than most cars. If you have even one or two small boost leaks you can have the problem you are having. You say the boost shot to 17 psi on the highway, is it set for this, or are you creeping badly. There are so many options and you have to sort through them. I doubt its your coil pack because the problem that is occurring doesn't sound anything like the ignition breaking up. goodluck
