Some guys selling a T25 turbo off an SR20 motor for $80 shipped.Its in good condition,but is it worth it since its only a T25? I don't know much about turbos yet,but I'm making a custom setup before summers over and learning as I go.How much power will I see with that T25? Or should I just wait,save, and get a T3/T04e for $400? Either way,I wanna get rid of nitrous for awhile..burnin' a hole in my pockets.

 

Amazing how people are supposedly making custom setup but dont know jack about the concept.

Its like putting a kids playground together that you so called custom built but dont know jack about wheather to use carbboard for the slide or some plastic that is safer.

Do us a favor and search on the internet or buy a book and see if the T25 is too small or too big. Or simple look in your noggin to see if a T25 off a 4cyl is still good for a 6cylinder.

Another 18yr that wants to be part of the IN crowd without knowing how to put the condom on first.

Haha jesus,someone put this doggy to sleep.BUMP...I need real help from non-as$holes.

Well I'm goin with the Garrett T3/T04e w/intercooler and wastegate for $1200.Good choice or no? (Please BigDog,keep your comments to yourself cuz #1 youre not funny;#2 I dont wanna hear 'em and #3 youre not tough by trying to make fun of an 18 yr old kid over the internet.Thats just gay.)

 

1) Read this section before asking repeated questions.
2) Bigdog probably knows more now than you might know in the next few years so calm down.
3) Continue with your insults and bad language and you will find yourself off of this board.

 

Ok ya know what,he probably does know a heck of alot more than I do...but all he needed to do was say,"yeah a T25 is pointless"...there wasnt any need for the rest of it.Sorry for the language but I just had a simple question that I wanted answered,no big deal right?

So anyway...is the Garrett setup aright?

 

the t25 is way to small unless you buy 2 of them and run 1 off each 3 cylinders aka twinturbo

 

Is a Garrett alright? Garrett what? GT20, GT30, GT35, GT42, GT60? Just knowing the 'buzz' words in the turbo/supercharged industry aint going to get you anywhere. Again you asking questions that can EASILY be resolved by reading a turbo book or simple searching on google.

Since you cant search I will let that slide, but why not just go to the different pages in this section and see HOW many questions we get asked about Turbos and people who are new to it and are wanting to make a custom setup.

So the T3/T04e from Garrett would be a good choice? Thats $1200,plus I need the piping which will be around $600,plus gauges (EGT and Boost?) and timer,and air filter? That all?

 

Sorry BigDog...didnt know there was alot of questions about the same crap.Well I'm doing this custom turbo right now while I have the money.Yeah I dont know much about it,but I dont wanna spend my money on useless mods.Plus I have every bolt on and some engine work done already.I would search google or something but dont know what to search for and thought it'd be easier to ask people WITH Turbo Maximas about this stuff.Once again,sorry for something thats probably been brought up over a hundred times a week.

 

Advice. Don't even pay attention to any other section. Look at every thread in this section and then look at your question again.

You will understand how naive your questions really are after you learn a bit. I mean really, you want to add equipment that will add over 80-120hp to your engine and that can EASILY tear your engine to pieces, and you don't know what you need????

Shell out the $ and buy a kit. That would be plenty challenging for you

 

where can i get a kit

EDIT: actually no...just let me know everything I need to do this custom turbo setup.Thats all I'm asking.Hey,if my engine tears to shreds,my fault.I'm alot more cautious than that though.I've rebuilt 350s and a Mustangs 5.0 before (with help of friends) and I've port and polished intake heads,and 3 angle valve job on the heads of my car.Have jwt cams on the way in the mail.And I'm not some stupid kid who just wants to hear "pssh" when he revs his engine.No body kit,no altezza,its a stock looking max with red/clears and clear corners.I'm not another ricer.

 

YEP..you're all set man.

go go go!

 

let me teach u how to fish..that might help you from getting tossed here.

5 seconds on google and i already found a place to get a turbo kit.

You've got a LOT to learn then cause your above calculation is no where near reality prices. Hate to be mean or harsh on you but you WAY off the mark on those numbers if you think you building a kit for a simple $2000.

Piping at $600? No way, unless you are buying them and welding the entire setup yourself, then $600 is conceivable, otherwise HELL NO. From the sounds of it, dont seem like you going to be doing the fabraication and welding yourself.

So The piping alone custom fabricated by a speedshop will run you in excess of 1000-2000 (depending on shop)

Silicone couplers, at least $200 there
Intercooler - $300-500
WasteGate - 100-200
New 3" exhaust - $500-750
FMU - $200
Gauges - 200-500

Should I keep going? Cause I spent well over $10,000 to do it right and only then was I able to put down in excess of 425whp. You dont do that buying walmart goodies. Cause it aint going to cut it.

page 44 of this section, subparagraph b, appendix a, footnote #3.

 

yeah actually i'm doing all the piping myself...I work at a CNC machine shop where we do all that stuff.SO YES I am welding them and most likely bending them.I've made piping for cars before.And the Garrett kit that I'm buying has the intercooler and wastegate with it,so $1200 covers those areas.My 3" exhaust will be $100 cuz I know a guy who custom makes my exhausts at almost no cost because I bring him so much business.Yeah I need the other stuff;gauges,FMU,couplers.But thats all correct?

 

@Dixit.

 

you cant just blindly add prices together without having an idea of what will be created. im sure you have some understanding of what turbo charging will do to your car but you need to first figure out what you want from your car. unless you are just buying a kit, you first need to create a plan of what kind of setup you want and how much you want from it and then you should start sourcing parts. by just randomly addig parts without knowing what each one contributes and/or effectes the mechanical operation of the motor, or even electrical for that manner, you are just setting yourself up for stepping into a river without knowing the depth. first figure out exactly how the car needs to preform after you make your kit, then design a kit that will fullfill your needs - just randomly adding parts is going to cause you trouble and big headaches.

 

What does a CNC machine shop have anything to do with welding or mandrel bending pipes for that matter?

 

the sr20 turbo is probably too much to run a twin setup without internals. man, if someone had a something like that there would be massive rapage over there

 

You know hes not joking?

 

Dixit, ppl weren't that mean to you when YOU were a newbie..

what machine do u work on?

 

CNC Machine shop...better than mandrel bent piping because you type the bend into the computer and the machine bends it for you.Therefore its not man made like mandrel bends.And welding because we've welded quite a few pipes together for cars,meaning we have all the tools at that shop.I work on the lathe and miller mostly.
But I duno guys...maybe I'm getting in over my head.Nitrous is gay so I wanted something more,but didnt realize I need to know ALOT more about it before I go and attempt it.So for now I'm buying a stillen v2 s/c setup...any objections to that? Make a little less power for a lot less money and work.Maybe I'll turbo someday,but right now I dont know enough about it.Thanks for all your help guys.In a weird way,all the making fun saying "you cant you dont know jack about it" kinda clicked in.Thanks.How much power can you get from those s/c?

 

aaaaaaaaaa nnnnnnnnnnooooooooo it would work just fine as long as you had the wastgates adjusted to the proper boost setting

what does having internals have anythign to do with using these turbos

 

thats true, i was saying sr20 turbos right off the motor cant be used. the boost would be to high for stock internals to handle. sure if you change the wastegate to a lower setting it will work...

 

I thought the internals on the VG,VQ and SR where the same(turbo/NA) no matter the application. I thought the only difference was the manifolds and comp. ratio?

 

the sr motor is a totally different engine than the vg and vq. the vq is based off the earlier vg design but it has a better cooling system internally. the sr is a four cylinder motor that is not even related to the other two. even if they were the same, the point of the matter is that the sr20 has one t25 whereas on the vq you would be putting two. both turbos are capable of flowing enough air for 300whp so 600whp would be possible on the twin turbo application. the vq motor would definetly be in need of internals at that point. of course, as stated before, if the boost could be controled lower than stock then it would be capable on stock internals but at stock boost you would be pushing the limits of the block when using two t25's...

 

I most of not typed correctly, let me try again. The internals for a VG Non-turbo and a VG-Turbo are the same(from what I been reading). The same is true for the SR(I know its a sentra/silvia-turbo). I thought that held true for the VQ as well. What I ment was why would the SR turbo's be too much for the engine? I understand there would be two but, that wouldn't really cause a break down internally,right? If they were twin sequintial turbos yeah that would need more cooling, heat wrap, or ceramic coating, with heat sheilds. I just thought the stock internals could handle around 500 hp.

 

500hp = about 430whp and the t25s are good to 600whp = about 700hp

im guessing that the stock VQ with 10:1 would make 600whp at around 22psi

so the stock vq internals would proboly not with stand 600whp althought its never been tryed by a competant person with good tunning knowledge so it could happen but is unlikly

what is the stock t25 wastegate set at anyway. ifigured it would be around 15psi

 

on the s13 and s14 motors its 7 psi and the t25 from a s15 motor is 8 psi stock
