crazy turbo wastegate idea!

[evil_demon_01]

but if thats the case can he just change the spring on the internal turbo the same way but more work?

The internal wastegate actuators are usually sealed units, you can't really open them up to change the spring.

Alot of them also only have one pressure inlet port, and for a boost controller you really need to use 2 for accuracy.

That's also true what Evil demon had said,

I'm yet to see someone change the spring in a internal wastegate, but I have seen people open the acuator by cutting it precise without causing damage but that's just to repair or modify them for certain reasons but there's no.need and too much work just to lower the psi.

Well now let me ask this, what is the wastegate psi on the 14b turbo? I thought it was 8 or 10 but a few other sites and one guy on here said there's didn't open till anywhere from 11 to like 14 and that's way too high! I just want safe boost so that's why I ask. Oh and from the external conversion research I've done it seems like I can remove the actuator and weld the flapper then something about you can put an adapter on the 14b manifold o2 sensor port then mount a waste gate on that? If anyones heard of that it would really help.

Yea the stock psi on a 14b is around 10-11 psi 12 psi when it spikes...it can be raised aswell.

Yea u can weld an adapter to the 02 housing and run off a wastegate by why go through all that trouble just get a manifold with one.

Well I just mentioned the adapter because the junkyard has everything I need as a unit. Its like 75 for the turbo and manifold. Everything else is like another 75. Pretty cheep Imo. Then my cousin can weld it all up for me so that's why I don't wanna spend extra money on another em.

and you read to much into my post.
Hmmm.. did I say a manual boost controller? Pretty sure I didnt. this whole thread is stupid. buy an electronic boost controller or run an external wastegate. Jesus. And you can safely run 15 lbs on a stock motor. I ran 19lbs on a 300k motor. it runs to this day, granted the turbo stuff is off of it. But it caused me no problems.

[hondakid1996]

Wow haha. Okay if its stupid then why comment on it? Like come on you're insulting a post made by a 15 year old. But this isn't a site for bickering its a place to swap knowlage. Oh and just sayin ebc's are hella expensive. But im just gonna make the internal an external and get a mbc set it for 8 psi and get a nice tune. Personally I think you were lucky with 17 psi on 300k but oh well im playin it safe haha. Oh ant to turboaccord do you think a p06 and a hondata s100 should suffice for an ecu?

[turboAccordHSF]

Ok ok lets keep all sarcasm and smart ass remarks to its limit, don't want this thread to be locked by a Mod or else it'll just be proven to be stupid.

p06 is a good ecu I mean its one out of a few that can be chipped and used on a cb7, Chrome and Neptune is two other softwares that u can use for tuning, but a dyno tune is a must.

Sweet. The ecu is the most confusing part for me lol. Oh now I see this site its jk tuning it says I can get a chipped p06 ecu with a standard basemap shipped for 125. Too good to be true? I mean that seems way cheep...

[zack_odom]

thats how much it is. Its cheap.
dont buy hondata when you can get tuned on crome for WAAAAAY cheaper.
I didnt know and dont care that you are 15 dude. Im just surprised how much you overthought a simple turbo setup. also I wasnt as you put it, "lucky" with my setup.
It was tuned with the right amount of fuel so that the engine could handle the extra boost.

SO much bad information in this thread, should be deleted.


Boost controller cannot lower PSI. PSI is pressure, not flow.




Sheeeesh. SO many noobs, so little time.



OP-



To fix your issue, tig weld a washer on the actuator arm, and use a long spring from the hardware store in between the washer and the wastegate.

The pressure from the spring you add will allow the wastegate to open earlier by assisting it.

**It is unreliabe to mod like this, meaning your never going to buy the exact spring to equal an exact boost. It will lower the resistance in the diaphram that is being controlled by the spring in your wastegate and that is it, meaning it will assist the wastegate to open earlier. It would be trial and error to find the right length of the spring/resistance etc...

But it has been done many times in the DSM world. Also, nobody is changing the springs on an internal wastegate. Some people will change the actuator arm, wastegate and all, but never ever the spring alone. The diaphram/spring area are pressed/sealed in a fashion that you would ruine it trying.
