20psi on stock fuel system

[1993gsxtalon]

ok i just bought my car not to long ago (2weeks) and did some maintenence and stuff but now on test runs i hit 20 psi in 3rd around 5500k mods are

stock fuel system that i know of
2.5 down pipe no muffler
evo fmic
"ported head"

and has cracked manifold.
i had boost guage tapped into P valve on throttle body ( was just capped off before;so i ran a hose straight to guage)
now its tapped into the bov hose and i get the same readings.

new to dsm but deffinately doesnt feel like 20psi from what i hear(especially coming from hondas)

please help. dont want to hurt anything

Damn beavis, I'm trying to get him to do some work and get to know his own car on his own instead of spoon feeding him.

Wellllll I am cornholio... Butthead.

Lol sorry guys a little late.

Ya well i pulled everything off today and im porting the o2 housing and rear half of turbo(turbine case?)and ordering the manifold

It went pretty good except for like one bolt. all gaskets and stuff look fine but i did notice that the turbine on that side has some play in it.(i felt the intake side a little while back and didnt feel any play) just wanted to know is this normal.

i will post pics of porting results

So you went ahead without verification? Oh well, I guess we will find out after you're done.

 

[crimsondragon]

the results should be interesting...
maybe the boost gauge is faulty.

Wow i knew porting was a slow process but dammm. Does anyone have advice on different bits or anything.
Its like im getting no progress

Die grinder with 1/4" shank carbide burrs.

 

[1993gsxtalon]

thanks ill try it tomorrow. Do you know how much they run, and where to get them

 

[oldman]

I don't think you can pick up carbide burrs locally. Are you using a dremel with 1/8" shank?

 

[MountainDew]

I tried porting. Used a rotary tool with a sanding bit . I gave up fast.

Die grinder is definitely your best bet. You should be able to get it at any hardware store I imagine. Maybe even an auto parts store as well.

i was using an electric drill with a wire brush type tip

Then I don't know what you can do. If you can borrow a die grinder (1/4") or a dremel (1/8"), you can pick up a cylindrical end DOUBLE CUT carbide burr from here, make sure you choose the correct size SHANK diameter depending on the type of tool you can get your hands on.

Allright me and some friends are going to see what we can come up with tomorrow

I think once you get your turbo put back on, you should check the compression. Its a good idea, and great piece of mind. Cross your fingers and hope that it is much higher than 116 PSI in all cylinders. That amount and less indicates you will need to perform a rebuild.

EDIT: Yeah porting does take forever, even with the right tools. A little patience goes a long way, and there is such a great reward!

The factory service limit on a 1G turbo 2.0 is 121, and the keyword is "service limit", I would consider 130's time for rebuild.

That said, compression is not the issue at hand since OP is over boosting, not under. However, I will agree that a compression test, just as a boost leak test, is always a good thing to do.

I think somebody needs to go back to school, so he can learn how to follow instructions.
Oldman knows what he is talking about.You need to follow his instrutions step by step and in order.
Dont just go doing everything you read somewhere because it sounds like your problem.
There is a troubleshooting process that will lead you to YOUR problem. Please note the YOUR problem. Not every other problem that everybody else has had that sounds like yours. There are plenty of problems that could cause your problem.
Listen to oldman and do what he says.He will lead you to your problem and help you fix it.

Ok well i picked up some of those carbide burr bits from a friend today and they were quite worn out. I managed to port the flapper spot so it opens 90 degrees and the holes on o2 housing and turbine housing to match and thats about it.and just a very basic port on everything

I have a lot of patience but this was different some how i had to give up...(how do you think it will turn out, dont get new manifold until next week so cant test)

Sorry no pics. lost camera cord

 

[oldman]

So so port job = so so results, you're the one who will have to live with the consequences.

I ported my stuff out, and yeah it greatly helped with spool-up, but I didn't waste much time creeping(using my foot as my boost controller) and just converted to SBR cast manifold and I already had a tial 38mm and a Hallman Evo in-cabin MBC. It was like a match made in heaven for rock solid boost control.

 

[1993gsxtalon]

what do you mean control boost creep with your foot..
And will my new tubular manifold help with boost creep
