hey guys. what do you think of this product as far as, performance and quality? I am drawn towards getting it for my 88 TII. My car is running the stock turbo with cone air filter,FCD, and full exhuast(No Cat) Will this be a good bargain for improving my car? I just want a small inexpensive boost controller that will give it a better than stock performance gain?

 

Would help if you said which one...

 

I'm sure it'll be fine.

 

Sorry guys, here is the link for the Boost controller in question. SO what ya say?

it will get the job done....but you would have to figure out what psi is safe........kinda on the dangerous side cuz if u do it wrong the motor is gone.....invest on a boostgauge also.

 

Forgive me, turbocharged cars are a new thing to me, but, what psi setting are you referring to and how can I determine that value?

I can go the complicated route if you need me to but here is the jist of it. The boost controller controls the wastegate.....the wastegate opens up to relieve the pressure that enters the combustion chamber to protect the motor from overboosting which can lead to engine failure. if you get too happy and turn the boost controller too high then the waste gate will remain closed at high boost(measured in psi) then your engine will detonate because it will not have enough fuel to compensate......

 

bleeder valves like the one you want spells boost creep
save some cash and do it right..will save you money in the end
remember No such thing as cheap HP

 

So if I wish to save money and do it right, what product do you suggest using? And BTW, the BC on ebay says it has a coarse adjustment which incorporates a ball and spring mechanism for large boost increases and a fine "air bleed" adjustment for very small boost increases of 1 psi at a time. ( Both Mechanisms )

 

dude stay away from **** people make at home depot and sell on ebay. Thats just advice from me to you. One boost spike and its new motor time. Then how much did you save on buying some **** of ebay. Spend the couple of extra bucks and get something that has been proven over time.

 

this is a great time to buy a good BC..lots of good products on the market...hks makes very good stepping motors and BC and so does Blitz..I had a HKS EVC EZ and it was easy to use but it produced a lot of boost creep...then I decided to go with a Blitz because of what I heard about their BC's...I went with the SBCDC

and it works very good...has a overboost function and a limmiter function that both work! three channels of boost and a scramble mode....and a very good dislpay...I am very partial to HKS BC's because they are good! I did alot of research...bout 5 months and decided that the one I have now gave me the most bang for the buck.....search the net for Blitz, HKS, greedy and APEXI boost contollers...read what they do and see what kind of functions you want....you will need to spend at least $250 and up to $450(maybe more)...one place I would look is on ebay...just take a close look at the pics and remember to include ship cost in your budget..some of the JDM sellers have $40+ shipping...

just be sure that what ever one you decide to go with has overboost warning and/or protection and a high and low boost setting...try not to go with a VOLUME(like the HKS EVC EZ) **** type of BC...in the end you won't be happy because you will need to adjust on the fly because in the 1-3 gears it will be ok but then in 4th and 5th gear the same setting will provide too much boost and vice versa if set to a good level in 4th and 5th...with a multi channel BC you can switch on the fly

 

I am partianl to the Apex-i S-AFC

 

First of all that MBC is not a bleeder. It is a ball and spring type and has an air bleed to relieve pressure when you let off the throttle so that the wastegate shuts completely and you don't have lag and for fine adjustments. It'll work just fine and you will NOT have boost creep. I am not sure where these guys get their facts, maybe they are talking about bigger turbos not stock. I installed a cheap one of ebay and have no regrets. Best 20 bucks I ever spent. I have set it to about 12psi and there is no boost creep or much of lag. If you have the stock turbo you don't want to go higher than 12psi and you really don't have to spend hundreds of dollars, get it and enjoy!

 

dont forget the fuel mods!

 

Hmmm. Indeed, I do have the stock turbo and I refrain from boosting past 11psi. So you say it works fine, but others say otherewise. Great, now I'm slightly puzzled. Well, I'd say I boost only in the range of 5 - 10 psi most of the time when I do boost.

 

So for fuel mods.... secodary injectors, fuel pump and FP regulator correct? is this all, considering my stock application and setup? I plan on upgrading to an aftermarket turbo in the future. But, my aim for HP is nothing big, just a little more than stock, maybe a turbo that makes 250-300 HP.

 

and a way to control the injectors( Apex-i S-AFC) in the post above I meant AVC-R(the boost controller). As long as you have enough fuel for the bigger turbo ur gonna be ok.....

 

i have had a $5 ebay one on mine for almost a year now. My wastegate is ported huge with a huge flapper door... but it holds boost right where i set it.

I would like to go EBC because my mbc on cold nights runs a psi more and hot days it runs a psi less...

 

Well, a lot of times people will merely repeat what someone else said online and you know how that goes. The MBC you have in mind was exactly what I was looking at. If I remember right, the seller has 100% feedback and had sold like 400 of these. That kind of customer satisfaction says something about the product. If you search a little you will see that there a quite a few people who bitch about EBCs also and the "fuzzy" logic. But hey, it's your money. Honestly, the concept of an air valve is so simple I would have made one myself if they weren't selling it on ebay so cheap. Just make sure the one you get has a tiny pin hole on the outlet fitting to act as an air bleed or a bleeder valve on the outlet side like the one you were looking at.

 

i made the DIY home depot one. It works as good as any other MBC. I remember there was an article in the SCC where they tested a bunch of boost controllers, manual and electrical. It turns out all the manual ones were much more accurate at controlling boost then the electrical ones. That's why i would rather have my home made one rather than an expensive ebc
