the comment about aftermarket is BS really. Japan is creating a plethora of aftermarket part for those cars that are very popular in Japan. New Ist is NOT one of them. Now, I view the power potential of the xD to similar to the late 90's Civics. not much there til you open up the intake and exhaust. add lighter pulleys and a clutch. gonna need that traction bar thanks to the really bad wheel hop and a rear sway bar. adjustable damping shocks wouldn't hurt either. but to see what just a cone filter does to HP and TQ ratings is impressive actually but not surprising. the airbox with two filters is rather restrictive. turbo'd xD's around 200HP is all you need. anymore and you may as well buy stock in Falken or something. I like a balanced power to weight ratio. not 400HP FWD cars. they're useless on the street where we drive them. especially in Chicago where every road all day is a traffic jam.

 

right on point jim... slowly but surely you are starting to see more and more parts for the xd... from tanabe / rsr / Aistar/ i would actually hope to see more engine mods for the car... i know certain companies stateside have had plans for the car that have been shelved due to the economy and lack of interest the parts...... as jim said i would say about 240 would be perfect for this little car... would be a rocket : ) .... and definetely a sleeper... but those of you who have put intake and exhaust on the car can tell the power difference...

 

I will like to know where have you seen lots of 1.5 1NZ-FE's engines pushings +200hp ??

Yes it can be done and it has been done... but it won't be long before you broke something. At 200hp the OE rods would be at their very limit. A hard lunch and you'll be throwing an axle.
OE clutch won't hold.
You need a built engine to go over 200hp

I've see up to 280whp on built 1NZ-FE's But we are talking of BIG $$$$ not really worth it for the average people.


The 1.5 engine has proven to be reliable in a stock form up to 150hp.

Higher than that and you really depend on the quality of your set up and you have a VERY small margin for error.
That's the reason why all the Brand name turbo kits and superchargers (Blitz, Greddy, HKS, Power Enterprises...) won't go over 150hp



Regarding the power capabilities of the 1.8 2ZR-FE I have come to some conclusions based on comparisons between turbo 1NZ and the only turbo 2ZR I know of...

I think is pretty accurate to say that the 1.8 engine will put around 20-30 hp more than the 1.5 engine at the same boost level with a comparable turbo set up.

About the limits of the 2ZR, I think no one can really say...

My guess is that if the 1.5 can hold 150 hp all day long with no engine modifications, a 2ZR-fe should be able to hold close 200 hp safely

You also need to put this kind of power on perspective...

A Scion xd with 200 whp should be way faster than a WRX subby.


As a few people said here, why do you need that much power on a FWD car? It would be totally unbalanced.

Personally I think 175-200 whp on these cars would make them super fun to drive!!
And still faster than 70-80% of the cars you will run into on the road.

 

exactly. a friend rebuilt his Civic's D16 for turbo. response is really good too. I'd say that car is approximately 190-200 hp. hell, mildy tuned S2000's can't keep up, but more importantly, the car handles really good. engine is built for turning if that makes sense.

 

200hp on the xd with an upgraded clutch would sound like a deadly sleeper. I wonder once or if they release intake manifold and headers and couple of bolt on parts can we achieve 200hp without the use of forced induction

 

i doubt it... simple bolt ons arent gonna cut it... look at tc guys.. they cant even make 200whp off bolt ons and they ahve 30 more horses to start off with... rofl.. i say 145-155 is probably capable of a na set up fairly easy.... if you want more you looking into full standalone, cams, pistons, headwork, tuneing....

 

The rule of thumb when it comes to boost is about 1/2 bar or 7.5 psi you'll get half your horsepower (128 + 7.5 psi = 128 + 64). I don't think that's to the ground though. With a compression ratio of 10/1 7.5 or 8 psi would probably be safe. I used to have a contour svt before I rapped it around a pole, and Vortech made a supercharger for the 1998-1999 model. I had a 2000 model and that year they decreased the size of the motor by 50cc, but raised the compression to 10.25/1 so that's why it wasn't available for that year. Anyway I can see a forced induction kit down the road that could make around 200 hp. No massive boost though. Also why does the corolla/matrix get a smidge more power?

 

I wish it worked the way it does with diesel cars -- more boost = more power with the SAME fuel economy. Totally different animal, of course... my 2003 Golf (when it was stock) pushed 17 PSI. New ones are over 20 PSI before mods. Plenty of folks pushing them to 30 PSI.

 

I used to own a 2008 GTI, and as far as I know...they only push about 13 or so PSI stock, once you start getting your ECU tuned, then you move on to 15 and above....I could be wrong I guess

 

I have had a turbo sitting in living room for months... I have almost all the parts associated with it as well... what I cant find (at a reasonable price) is a manifold... When I find someone willing to make a mani for a decent price I will be boosting the xD...

I need:

Turbo exhaust Manifold
Turbo dump pipe
Intercooler (that will fit under the stock crash bar)
oil/coolant lines
Time

 

Nah, you're just thinking about the wrong turbo VW. I'm talking about TDIs not GTIs. Some of the higher-powered turbodiesel cars in Europe are pushing over 30 PSI stock! I think Renault was working on one that boosted up to 42 PSI.

 

yea, America is suppressing diesel technology for our cars. sure there are the euro's offered here, but everyone else can't bring them here. and diesel tech is gettin rather clean too. a sidenotte about clean energy: in northern Illinois, one city doens't want a wind farm cuz it will make too much noise. wtf is that?! that type of thought process is why things are the way they are

 

I remember chiming in on a thread a while ago that I thought was "intake" manifold related, but really was an "exhaust" manifold conversation, and that there might be some kind of exhaust manifold out there from another toyota model that fits ours? I will check my posts and see if i can find it, you might be in luck.

 

ok I found it...and you might be in luck...

The above quote was from the Untouchable's Turbo Thread CLICK HERE to read more This exhaust manifold stuff was mostly on page 2 of that thread.[/url]

 

please do, I contacted FCR or FSR something like that , and they said that they could make one for around $1200 or $1400, maybe I am used to the 240sx days where the manifolds only cost a couple hundred bucks, but I am not going to spend that much on a manifold...

 

really... hmmm... lets see if I can find one then... I wonder what modification would entail....

 

you're welcome.
good luck, and keep us posted on any findings

 

lol sorry

Thank you

I will keep people up to date on the progress

 

yah its a 1zz exhaust mani i believe... ... if it is you can swoop one on ebay and just do some minor adjustments and get that baby turboed

 

Yeah, maybe they wanted to make a SECRET product!
