what are my options?

[j30-tsi-awd]

hey guys whats up?

Alright heres the deal.
I was driving to work today, and I noticed a strange moan almost coming right before I hit boost. This was at about 2700-3000 RPM, and about 5-7 VAC. Then when I get on it, it makes a high pitched whistle at around 10 psi. There feels like a major power loss.
So im guessing that my t-25 is going bad. Im pretty sure that its the original turbo and it has, 180,000.
My 1st question is. is the t-25 going bad?
2nd What are my options on a new turbo?
I have a new jasper motor. stock fuel system, Greddy type s bov. Nology hotwires. and a N1 downpipe and N1 catback. i have a turbo xs dual stage boost conroller but i need the harness for the siliniod to make it work.Theres my mods.
What do you guys think my options are.
Im thinkin a small 16g ,but im totally not sure and I will consider pretty much anything. I Would kinda like to keep it the stock fuel system. I also still have the stock smic so id kinda like to keep that. I dont plan on taking my car to the track. Its my daily driver, but i still want to have to power as my disposal.

thanks for all your imput and help!

oh ok i understand now.
could i hook up a water sparayer, like use a old injector on my stock side mount to keep it cool?
like drain the rear washer fluid and fill it with water and run a line to the front? and just use the button on the dash to control the sprayer?

A water sprayer for the outside of your intercooler will cool your intercooler down quickly after it does a bad job of cooling your aircharge . When I mean water injection, I mean injecting a mist of H2O ito your intake tract just before yout throttle body valve. Its simple to set up and kits can be had for much, much cheaper than a front mount intercooler kit. AND, it does a much, much better job cooling the intake charge. AND it has the added benenfit of increasing the effective octane of the premium (91-93 octane) gas in the combustion chamber to over 109. Where can you get 109 octane gas for the same price as 91-93 pump gas? Reseach this. There are a few very informative threads on this...

This is the second thread where my reply is getting posted out of order. ????

 

[vintagemuscle]

cool, thanks for the imput. I ordered the "total solution" package and the fuel packager as well. i got the 650 cc injectors with it. whats this I hear about a fuel pressure regulator???
im kinda confused


thanks


-scott

if you ordered the fuel package with the 255 pump you are also going to need a adjustable fuel pressure regulator to compensate for the extra fuel. the stock fpr cannot send enough fuel back to the tank resulting in a very rich condition at idle.

 

[j30-tsi-awd]

alright thanks vintage.
So i need a frp ok. Im on very limited funds since I blew the rest on the other stuff. I need recomendations and suggstions as to what to look for in a frp?
Whats a good cheap one that will do the job. Im not lookin for anything fancy. What do you guys think about the megan racing one its only 70$ on SBR. Thats kinda around the price range I can handle any thoughts on this product ?
From what Im understanding, I need this frp because at idel the stock one will flood. is this correct?
I will be ordering this tonite so I apricciate the feedback
thank you

[vintagemuscle]

afpr's aren't cheap but you can find them for about $150 and up. check import evolution, as they have the cheapest afpr kits that i have seen. stay away from really cheap fpr's (ebay) as they tend to leak, do not rise on a 1:1 ratio and are overall bad quality.

 

[j30-tsi-awd]

what about the megan one on SBR site?
will that work? is it 1:1 and "bolt on" from what ive gathered here on dsm tuners...its a pita to install. and its not very reliable? is this true? Should i just go with the aeromotive one on SB? if i get that will i be "bolt on" and ready to go?? or do i need more stuff



thanks!

[j30-tsi-awd]

AWESOME!
Alright heres the list of everything I ordered. I ordered It all from Slowboy. I didnt want to risk getting knock off's, so I went with a "reputable" shop!

-Evo III 16g Turbocharger( not ported)( no extra cash...)
-2G Install Kit
-New SBR DSM Cast Manifold (also not ported)( again just didnt have the extra cash...)
-Set of 660 CC injectors
-Walbro 255 fuel pump
-A-pexi S-AFC II
-Aeromotive fuel pressure regulator
-Autometer carbon fiber fuel pressure guage
total cost = $1882.58

What do you guys think? Am I missing any key parts here? Am I ready to go?
Its gonna be a sweet set up once its all installed.
I gotta try to figure the S-AFC II out though I have no Idea on that. Any suggstions, or final tips for me?

Thanks dsmtuners you guys are the best! keep the info comming!


-Scott

 

[dsm-onster]

I understand, But why take the risk? If you have money sure. But most DSM wouldn't want to be expending money on turbos every 2 months or so....
read this link

Give me a break. I had a small 16g that popped after 1 year of usage... I know many, many MHI trbos that have found their home in the land of the eternal turbo paradise. Just becasue MHI is the most reliable does not mean it delivers performance anywhere near it's reliability record... If you want to play you gotta pay. No high performance turbo is going to last along time and mostlikely, YOU are going to install it wrong or install an important component wrong... Bottem line, I've seen more MHIs fail than EVO3 GTs... the evo 3 gt gets negative hype just like propane and water injection did. "it's new and its been used on diesel trucks. So its not for me" And meanwhile, you're slow and you're knocking like an insurance salesman. Keep the reviews in the proper forum: parts review.

I'm not flaming you. I'm insuring that this thread doesn't get stupid like all "what turbo is for me" thread gets. I know the original poster doesn't want his thread to get locked...

Your stock intercooleris going to heat soak at any boost over 17 or so psi... But you will have enough fuel for 28-30 psi. WTF

Have no fear. Cheap ebay intercoolers have been proven to work just fine. Look on ebay and get a front mount, fab up some piping, and run the boost you want. If laying pipe is not your thing then I suggest a basic water injection kit from becooling or engine round up. The only other option is 500+ bones for an front mount "kit". At some point, you'll have to realize that it's better to fish around on your own to find the deals and piece something together that will work for you.

 

[j30-tsi-awd]

so...im alright for now? correct? im gonna set the boost at 18-20psi and It'll hold me untill a few months when I can afford a front mount and new piping.
Im really excited about this! thanks for the help keep it comming because I sure need it!

No I said that your stock intercooler is going to be heat soaked too quick at anything ove 17 psi. Probably less. It's not safe to run over 15 psi with the stock IC. . . . . There is no need to buy what you bought without paying more for a FMIC "kit". Or being smart and fabbing up your own piping and grabbing a cheap FMIC off of ebay for cheap.

I dont understand why you went all out on some things and passed up on the crucial stuff?
-you should of got the turbo/waste gate ported for one, your gonna get boost creep!
-an unported cast manifold to me is no better than a stock 2g
-should port the stock 2g exhaust mani
-walbro 190, no fpr

all honesty you could have paid a few more $ for the big T-28, bolt in on and run 10psi with a ported manifold and run a 8.5 in the 1/8th, thats a fast street car with minor modifications and still come out cheaper! you can always add a "pos" afc and some injectors out of an evo (560s), walbro 190 and turn the boost up.

Im not trying to sound like an a$$ but I think you could have done a lil more research. Seems like you rushed into it good luck

Hey thanks for the imput.
1st off i didnt have the cash to port that stuff out. I work at a mechanic shop so if it really is needed then Ill port it, why waste the money if i dont have to?
2. my stock manifold had several cracks in it. so i just went with the "total solution" kit from SBr
3. i wanted a walbro 255 to give me the flexablitly to upgrade in the future. why pay more later? plus SBr offerd a kit so that was just what i was looking for, fuel pump and 650's and afc.
4.about the t-28...all it comes down to is.. i choose the evo III. I have a freind who has it and he loves it. personal experince i guess.So thats what i chose

yes i can see where your comming from. but i dont have the time. i need the car for school and work.. and im borrowing a freinds but i cant use it for more than a week so it was rather rushed, but i did do some research as well.. im still a noob here w/ dsms so im learning. dont worry about sounding like a a** I call it constructive critisism and i apricciate your feedback thanks

any other opinions or thoughts?

I am not experienced with the intercooler sprayer first hand however I am familiar with it. I think spraying the stock side mount might help a little but I would obviously reccomend a front mount it doesnt have to be a huge one for a 16g but a good 7-9" tall one would suffice. Another idea that would work is a supra tt side mount, if your not familiar check this out www.vfaq.com theres a nice how to on installing it too. there also an abundince of info on this site about the supra smic and theres about 10 or so in the classifieds!
first thing you need to do is come up with a goal. ie: fast daily driver, street/strip, race car
that will determine what mods to do and when to do em. sounds like your on the right track. about porting, it is required on that turbo with that open exhaust. you will get boost creep. makes it hard to set boost levels etc.. its not just for performance allthough it helps spool up time tremendouly. then again an external waste gate will also solve boost creep but cost alot more than porting!
