Stock SMIC guys, need your opinions please

[dsmdeliveryboy]

Ok so I'm picking up a 2.5" hard UICP tomorrow, its the older HKS UICP with the black piping and HKS throttle body elbow and its flanged for my 1G bov and what I want to know is how much power everyone else gained from upgrading their uicp? I'm sort of skeptical on gaining power from it like people say but I'm jobless and hurting for a little more power and am picking it up for super cheap.

Current mods:


-14b w/16g 7cm housing
-Ported Evo III manifold from Mach V
-Victory Performance o2 dump
-Balance shafts eliminated
-Kevlar timing belt
-ARP headstuds
-Metal headgasket
-ACT2600 clutch
-Jacks racing transmission clutch fork and fulcrum ball
-Solid shifter bushings
-Unknown name MBC@15psi
-Autometer boost and EGT gauge
-K&N air filter
-KYB struts
-Walbro 190 fuel pump
-Magnecore 8.5mm spark plug wires

Also, a little off track.. I'm experiencing weird boost spike problems, I think it may be my mbc but I'm not 100" sure but it will spike to 19-20psi and I don't hit fuel cut or anything and when it did that it kinda scarred me so I just turned it all the way down but I'm just so lost as to what it could be.. I'm still running the stock exhaust but I heard it doesn't get restrictive enough to make a difference till around 300whp.

thats a good mod list. The boost spike is probably your boost controller like you said. The better flowing exhaust, the better, but when you flow more air you will have boost creep issues unless you port the wastegate flapper area and cut the divider out of the o2 housing.

The problem with the flapper is I don't know if I'm going to be sticking with the 7cm housing, I want a 16g but don't have the $ for one just like exhaust and the way the o2 housing is there is no way to divide it, there is piping for the dump and piping for the exhaust, they don't meet between.

And I was also wondering if getting a different turbo outlet and lower intercooler pipe is necessary or worth it?

I had a very noticable increase in power going from stock to 2.5" with an evo 3 at 30 psi on e-85.

Lol thats twice as much boost as I'm gonna be running and a different turbo and on e-85.. Kinda has no relevance.

Good point. So shouldn't that answer your question? Your NOT going to be able to tell a huge difference at all. It's not a pointless upgrade, hard piping is ALWAYS good. BUT you mentioned your jobless? I would probably save my money, but if your getting it for "super cheap" then why not. You have a nice amount of upgrades.

I would suggest getting the piping, rewiring your fuel pump if you have not done that already, a Wideband and eventually an exhaust. It opened up the potential on my 14b instantly.

You didn't ask if anyone with your exact setup and boost level changed piping. I gave you my direct EXPERIENCE on the subject, not some "i read it on the i nterweb" reply. In fact, i'm the only person in the thread the offered my own real world experience.

 

[dsmdeliveryboy]

That is true, thank you everyone for your replies. Sorry if I was out of place, a little intoxicated last night . I'll let everyone know what happens.

And I'm in the process of trying to get a wideband and exhaust, right now I'm concerned about my mbc because its not working properly and I can't find my bcs to put back on.. Need to pull out the DSM random parts box .

 

[clockworktoy]

It will be an upgrade, and im sure you'll feel a difference on the butt dyno. Have you ever seen how much the stock rubber pieces balloon under boost? And i agree with the MBC being the culprit of your spike. Make the lines as short as possible and get a new one if you can.

 

[dsmdeliveryboy]

Got the intercooler piping installed, it was a pretty decent upgrade. Got the boost spike problem taken care of for right now as well. I have a vid, I'll post pics later cause I'm too lazy right now .

Upgrading your intercooler simply allows more boost to be run at a given temperature due to more efficient cooling.

If you are considering an intercooler upgrade, you might as well do it right and get a front mount. It will save you money in the long run (instead of having to upgrade twice) and will have access to more mass flow rate from ambient airflow than a sidemount would, otherwise.

Alternatively, you could add a meth injection to help aid in the job the sidemount would otherwise do by robbing the airflow of heat in exchange of atomizing methanol.

There are several options available to you. Any of them (as an alternative of using the OEM sidemount with 2" in/out) will allow an increase in performance and allow you to run more boost later on further allowing an increase in performance (allowing an increase is dependent on your tune).

I already plan on running meth with the stock smic, I guess I should have clarified that before .

Either way, adding meth on an upgraded intercooler will still permit a colder air charge for the given meth/water mix. I would seriously contemplate a new intercooler.

I've thought about it but I'm gonna be doing autocross and I do canyon driving and I wanna be that guy people know who runs the stock smic with meth etc ya know . Believe me, VERY MUCH contemplating has gone into this. I waited 7 months to buy that uicp for that reason, and if I do ever decide to just go ahead and get a fmic the uicp wasn't a waste of money at all.

Yea, the whole bragging rights of limiting yourself. Don't do it. Just setting yourself up for excuses as to why your car doesn't perform.

Totally agree with this, with a proper intercooler, ducting, fans, heat shields there is NO reason to have any type of overheating issues to occur. With that being said the stock sidemount sucks and isn't very efficient and even an upgraded sidemount isn't going to be as efficient as a proper front mount.

 

[dsmdeliveryboy]

I'm not in it to makes tons of power, that is what everyone is not getting. I'll be completely content with the stock smic and meth for what I do, and if I want I can easily upgrade. But I appreciate everyone looking out for me

What are my options as far as modifying the stock smic go? Could I make the inlet/outlet bigger?
