This will be my first post on my new account, since I somehow managed to forget all my previous account information. This is something I need to pick everyones mind on...

Bear in mind that my knowledge of a lot of performance aspects of cars are minimal to moderate at best. If you're going to flame or call me a retard, find another thread, because I'm trying to be serious here.

I drive an '05 xB. I've already upgraded certain performance aspects of my vehicle, and I'm ready to take it to the next level. I've managed to (according to estimates from my GT2 performance computer) make about 150hp out of my little 1.5 so far, with a peak of 178hp at certain rpms. Not bad at all, enough to smoke most people driving around here, but I desire more. On to my point of writing this...

I have a friend with a 2003 VW Golf TDI (Turbo-diesel for the v-dub ignorant). He's upgrading his stock turbo to something (like a GReddy) that will handle a bit more constant boost, since he's overboosting to about 20-23 psi due to pre-emptive fuel programming where he planned on the bigger turbo.

He's offered to sell my his stock turbo, all piping, and intercooler for a really low price ($150). My question(s) is/are:

Will this work in my xB?
Will the piping fit, or do I need to buy/fabricate new piping?

Also, I understand the need for a stronger intake manifold, and that an xB stock block will safely run about 8psi of boost. My other question is, would I be able to safely stick to the stock lexan intake manifold, even at any boost level, or do I HAVE to change it right away when I install the turbo? If I don't change it out, what level of boost can I safely run without damaging the manifold?

Also...

Has anybody tried running nitrous on their xB?
What shot (25,50,75,100, etc...) did you use?
Does the motor hold up well with nitrous, even in small amounts?
What other stock internals did you need to upgrade to run nitrous?
Would you recommend running nitrous at ALL with a turbo setup in the xB?

and...

What top speed have you managed to reach with a turbo/nitrous/both installed?

Ok, so I have a lot of questions. I'm sure this will keep everyone interested with plenty to rant and rave about. Sorry if any of these questions seem stupid to you, just keep in mind knowledge is limited, that's why I am asking.

If you're going to tell me upgrading to a turbo/nitrous is stupid, or that I shouldn't drive so fast, click the back button, read the name of the section you're in, and go kill yourself. I'm not asking for approval to drive fast. I make my own moral/legal decisions. Just help me with the information I need, please.

(Sorry for the last paragraph but a lot of people on here come into performance threads and scold us for driving too fast. They should make another section called "Wussy Drivers that Make You Late" and post it in there.)

Ok, I'm done. Pander to my inquisitive mind!

 

how the hell did you pull 150whp out of our engine without a turbo... It seems a little unlikely.

About VW turbo's: Im not so sure about the diesel side of things, but my friend has a 1.8T and its $HIT!! After 2 hard runs the turbo turns into a giant red light bulb... It gets so hot and the intercoolers are so inefficent that he actually looses power when he accelerates. Im not sure if the TDi uses the same KKK turbo, but if it does stay clear. They are tiny little turbos that get really hot really quick. Dont get anything bigger than a Garrett T25 because anything bigger is just too big and lag will not be your friend. If you could tell me exactly what kind of turbo the TDi is running with i could give you a better answer.

 

Let's start with the TDi turbo setup first. Don't waste your time with it. The stock VW turbos on the TDi are small and heat up quickly, the intercooler setup is not adequate and is prone to heat saturation, and the turbo setup would cost you $$$ anyway to get everything to fit properly as well as the necessary F/I Management and tuning required to get the setup to operate properly.
If you are going to spend the money to get a turbo setup, do it right the first time and save yourself the headaches. A $150 turbo setup seems like a great buy until you calculate in the extras. Also, turbos that have been used and abused run the possibility of being scored and damaged. Depending on the age of the turbo and the pounding it has endured, it could very well need a rebuild, which would be extra $$$.
Your best bet would be to purchase a turbo kit designed specifically for the xB if that is the avenue you intend to go. You'll get much more bang for your buck without the worries of the life of the snail or the possibility of the kit damaging your motor.
Nitrous is not as bad as it is made out to be as long as it is used WISELY. Most people do not understand the concept and immediately imagine a motor grenading at the push of a button. The concept is very simple. A motor works like a pump. In comes fresh air, full of oxygen, out goes the spent and unused gases as waste. The more oxygen and fuel a motor can add to the mix and properly consume in the process of combustion, the more efficient the motor is, and the more power it creates. Nitrous is simply a larger percentage of oxygen based on volume. The nitrogen used in the compound is not consumed and is tossed out as exhaust. In order to accomodate the increase in oxygen, there must be a proportionate increase in fuel as well. This is where the problem occurs. Without the necessary fuel, the motor runs too lean and BOOM!!
Running a 35-shot with the appropriate amount of fuel will be fine on stock internals provided that the owner does not make stupid mistakes. My suggestion if you are wanting to run nitrous is that you purchase a "wet" shot that includes the proper fuel solenoid along with the nitrous, as well as some sort of WOT microswitch or a window switch to keep the nitrous from spraying during a decrease in throttle.
As for running nitrous and a turbo... it is possible, but the necessary tuning may be a bit more than you are willing to do. Most turbo kits are designed and tuned to optimize performance for the turbo itself. Adding nitrous would require additional fuel as well as timing retard to prevent detonation which would KILL the motor.

 

yeah, just get a zpi turbo kit. and it seems that zpi found out that 230 whp is the limit the xb's axles can handle.

why not just put the whole 1.9l tdi into that box!!! mmmm torque and 50mpg. that would be hot.

 

Right now you are in over your head. Forget about the turbo from the TDI. Start reading up about turbo xBs and turbos in general. Ask general and specific questions of people in forums who know what they are talking about. Then make an educated decision for yourself.

DO NOT FOLLOW INDIVIDUAL RECOMMENDATIONS BLINDLY!!!

 

why would recomend a kit not available?
way to help a new guy....

 

see above

 

Very sound advice!!!
Although there is no better teacher than experience, it will certainly make things MUCH easier to handle if you have a good understanding of the topic. Messing with nitrous and FI is NOT to be taken lightly because simple mistakes can lead to COSTLY repairs! The concepts are not rocket science, but they do require some forethought and planning. If you choose to ignore RT's words, I hope, for your sake, that you have a HUGE wallet and enjoy walking!

 

the kit is availiable, it is right here

Bwahahahahahahah!!!

Too bad there isn't an emoticon that is a smiley face that looks like a sucker.

 

 

there is not one retail sold kit out there....

 

doesn't mean it wasn't helpful. the guy wants a turbo xb. i gave him the link to a turbo kit for the xb

 

and it has two rave reviews, must not be all bad.

 

Give Todd a call at Why Industries TurboToyotas). He can help.

 

hey not to be rude...but you can order but not get the zpi kit only..there is not one retail kit shipped sold that has been shipped and installed as far as we know..only sponsored cars have this kit currently...

 

yeah all bad sorry .....

 

i'm lost her, you can go to zpi online, order the kit, and not get it? just cuz noone has ordered and installed one yet doesn't mean it's a bad idea. i know they installed it on there sponsored cars to test it out before they packaged it. but anyway, it has to be better than using a turbo from a vw tdi.

 

Both reviews were from users who have the prototype kits...not the production/retail kits.
