My friend and I are having this big debate. He seems to think that you can get a scion xB to be pushing over 200 horses. I say you cant. He is saying that you can put in twin turbo and all this crap but I seem to think different... Anyone know who is right???

 

well, i dunno, anythings possible. but i highly doubt it is. the only way would be an engine swap.

 

The 1nz can push over 200hp, theres been at least one echo i've heard of on echo forums with 205whp boosted. Different ecu, so you'd have to swap our ecu with theirs but its possible with the right funds, and extensive planning. In terms of twin turbo, i'd pay your friend to do that and have the motor last 1,000 miles.

In terms of motor swaps, anything is possible. Theres two 400hp xb's, one has a 22rt motor and a truck frame, the other one has a different toyota motor, forgot the specs on that one. Both are pointless to me, especially the 22rt one since its no where close to being an xb except the shell.

But with the 1nz, its possible. Its been done, not without a ton of work. ZPI is planning to hit 12's in the box, which means they would need roughly 200-210whp to acheieve this, given the weight, gearing of our cars.

 

you "could" do 200hp depending on what "all this crap" is.
you probably cannot fit two turbos under the hood nor would you need to, one turbo would provide plenty of boost to blow the engine.
Mostly though it seems like your friend has no f-ing clue what he's talking about and you should'nt listen to him. at all. it seems that your not that concerned with power and that you'd rather have an xB than a fast car. good for you.

 

OK so the only way to get that is to spend a load of money or do an enigine swap... thx... oh by the way, I would take an xB over any other car in the world except for a nissan 350z just because i love the way they are designed...

 

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
youd take a xb over any car , you poor thing you should get very sick and eventually die LOL jokeing

 

Twin turbos on inline motors are not that great an idea. The execution is VERY difficult, the risks are great, and the gains are minimal. V configurations however....


as stated earlier, one turbo is sufficient to blow up the motor.

But, could you say, use a truck load of money, to rebuild the motor, and reprogram the engine management to handle 30psi? That's another question for these other technical cats on the board.

 

inline ? um yeah 6 cylinder they work fine. but a turbo per two cylinders is stretching it and probably wouldnt have enough exhaust velocity. hell or volumn

 

Would have no where near enough exhaust velocity to do any justice. You could probably run dual, very small, 3psi turbos. With all the custom work into that, wouldn't be worth the trouble. Best go with single turbo.

 

with proper engine internals and a good engine management you can do anything. Use a 20G or a GT35 turbo and you will get a good spool. You have to beef up the transmission though.

 

GT35

 

i was thinking the same thing. these engine onlye rev to around 6500 anyway. maybe on a vtec you could do a GT35 and have no spooling problems but i dont think so on the 1NZ-FE

 

Quick post from me. I did some research and found the flow rates of a GT35. You are right. Higher RPM response. You could go with a modified exhaust housing though.

 

ever seen the audi tt?....which came first the audi or the 350? do the right choice get a 4wd original instead the one that steals a design from another company. SKYLINE on the other hand is amazing

 

200 hp IS attainable..

The only problem is

SPEED COSTS... HOW FAST DO YOU WANT TO GO? (HOW MUCH YOU GOT?)

And what is realistic on your budget? or just buy a faster car if speed is all you want.

Or are you looking for a sleeper, show stopper, 1/4 mile car, auto crosser etc.

What are you trying to get out of it?

Good luck

 

if you want 200whp reliably, expect to spend around $10k.

err......i would say more like 15k for that much on this little car with little engine!

LOL

 

new pistons, rods, studs, seals, machine work, etc will run $6k easily. not including turbo set up.

Anyway, there is someone named jamie coriano who is supposed to have an XB than runs 13.1
If he is on these forums, he would probably be the person to talk to since to run those times he would have to have 200whp+

 

You could make 200+whp for under $ 1,000.

The kit that Ctrus and myself are making has an M62 blower, it's more than ample to push enough boost through it to produce 200hp on the 1NZ-FE.

Before you all attack me, there are two things to know.

-- 200HP is easy to reach, but that does not mean it would hit that mark more than once... All it takes is a ton of boost and enough fuel for the combustion.

-- Once 200HP is hit, how will the motor hold? How will the trans hold? Where are the weak spots?

These are questions Ctruss and myself intend to try and answer. There are reports here and there of high HP 1nz-fe's but no real details. I will be disclosing EVERYTHING we do to these cars and the power levels they reach.

I am also going to buy a junkyard motor in the future, hook it up, boost the hell out of it and wait for it to fail. We NEED failures under PROPER conditions with PROPER documentation to know just what we need to strengthen.

It could be that one little bolt in the trans simply needs to have a harder version of it put in and the car could take 3,000HP, or it could be that the rods suck but the pistions are fine, or the pistons suck but the rods can hold 500+HP...

Nobody really knows. I, however, would not put the thought of 200+ reliable HP out of a very close to stock setup out of your minds. I do intend to put my money where my mouth is, do some real research, disclose all mods and failed parts (if any) and have fun with my car.

While twin turbo's for 200hp would be overkill, it could be done. Some people here attack new ideas so fast without much basis on fact. Where there is a will there is a way. You say there is no room for twin's, well if you pull out the stock airbox there is enough room there for a kitchen sink.

Anyway, long post.. sorry. Hopefully these questions like this can have a solid answer in the future.
