wouldnt it take close to 10Gs to get 400 HP CORRECTLY??

No thanks, ill buy a supra, haha

 

You've got your internals planned out?

Do you have your car planned out? Why 400 hp? What are you going to do with 400 hp? Race? Do you have your transmission planned out? How do you plan to finance all of this?

The amount of money it'll take you to get 400 hp safely would buy you something close to a Corvette with 400 hp stock.

Do you just like modding? Then why do you want 400 hp?

It doesn't sound like you have a good grasp of just how much power 400 hp is. 300 hp is a good goal. There were plans for 400 hp kits by ZPI but they scratched that idea because it was unfeasible.

Don't get me wrong, I would love to see a home-built 400 hp tC. I just don't see an 18 year old knowing fully well the magnitude of the monster he wants to create.

 

I'm planning on getting my car to about 300whp...

what would be the best course of action

i'm thinkin just goin with a ZPI stage 1, but i might do a vvt controller with a stage 0...

any other ideas?

 

Hey you dont have to down on the 18 year olds not all of us want a 400+ whp tC, lol but what you are saying is true.

 

Mm, I meant the specific 18 year old who started this thread. I don't like making blanket generalizations but still, generally speaking, most 18 year olds who want 400 hp out of a 2AZ won't know the magnitude of the monsters they want to create.

A "sensible" person won't want more than 350 hp. Past 330~ whp, one's engine will ask for a LOT of TLC from its owner.

For the most part though, I don't hold age against people. There are plenty of 16 year olds who have more wisdom than many 26 year olds... not a whole lot but plenty all the same.

 

Wow, your way off base. You want 400whp here you go.
GT30R turbo kit $5000
Clutch $ 500
800cc Injectors $ 500
Quaife LSD $1200
AEM EMS $2000
Aquamist $500
Scion TC $ 16000
LC Pistons $1000
Misc. $1000
Total $26700

That will easily get you 400whp on pump and that's for less than the price of a STI or EVO. 400WHP is pretty easy with an appropriate turbo and a good tune. Water Injection helps big time also.

Now Labor, that's another story. Do it yourself and really learn about the vehicle.

 

400WHP can be done quite easily if you have internals and alot of money.

Edit: I see tcengel already said that.. I guess I should of read page 2 before posting.

 

total: $27700

 

I's not so smart. Sorry.

 

hahaha dont feel bad... ihad to use a calculator...

 

My car is currently being turboed right now I have a turbonetics T4 60 trim turbo I plan to put an AEM computer should make around 330 whp on stock internals no prob...Dont these guys at ZPI have 400whp on stock internals? I thought they did.

 

No, don't check out ScionSpeed. I ordered a turbo kit from them almost a year and a half ago and they never came through. They're currently being taken to court for basically stealing a lot of money and funding that nice little ride they've got there.

 

Wow, there is a lot of false info. in this one.

1) You would be near 300whp out the box with a ZPI stage 1 kit.

2) It takes no where near $27k dollars to build a 400whp tC

3) Yes ZPI has 400+whp tC's, internal wise I believe only had turbo pistons. And I beileve they have had some on stock internals too.

4) If mommy and daddy are funding his car, what does it matter how much money he spends on the build.

5) ZPI at one point had a 20G on the Silver car, and then I beileve they slapped on a GT35r on it at another point in time.

If I had to choose, I would do a 20G. The 16G from the Stage 1 is rated to handle 400hp, but that's at it's limits, so I wouldn't want to stretch it that far. So, WHEN we are near 400hp, I probably will have Kenny slap us a 20G on it and turn up the boost.

YES, you need a built Motor to make it last and worth driving hard on.

 

If you read again, you will see that includes the price of the car. If you do it cheaper than that safely I will be very surprised.

 

here is what you can eliminate from that price list.


1) GT30R (cheaper smaller turbo can make 400hp)

2) 800CC Injectors (injectors in the ZPI stage 1 kit would handle 400hp, and that's included in the price of the kit)

3) You don't need an LSD, although good edition. And only useful if you are doing drag strip/from a stop races

4) AEM EMS (cheaper E-manage can tune a 400+hp tC any day, ZPI does it all the time)

5) Pistons (questionable, but a good investment nonetheless)

Now recalculate and tell me what you get, I'm going to lunch. BRB.

 

Wow, your new at this huh. Maybe your thinking crank HP.

1)There is no way a 20G will make 400WHP without VP16 and cams and head work. Sorry, it's not gonna happen. You'll be really lucky to make 400WHP on a GT30 even.

2) If you are making 400WHP on pump with anything less than 800cc injectors, say goodbye to your engine.

3)You need an LSD if you want to go anywhere. Have you ever had a ride in a 400WHP car? My 91 MR2 made 330 WHP and all it did was spin the tires. That was with 265/45/17 Falkens and an engine sitting over the rear wheels.

4)E-manage is crap. It has a hard time controlling timing and without race gas and a built motor for extra protection, say goodbye motor. You need full timing control at that horsepower level.

 

1. We have seen as high as 375+ WHP on a 16g (an evo III GT 16g) on our cars. I think with our longer stroke motors plus the offset crank makes our cars run a lot of torque especially on a turbo car. Now if we can get 375 WHP with a 16g I think 400 WHP with a 20g is very feasible.

2. ZPI used 550cc injectors on the 375 WHP dyno. Also SC owners are getting up to 250 WHP with 410cc injectors and I believe they still are not near 80% duty cycle and if you include the losses of the actual SC... you get the picture. I think the BSFC of our cars are lower then traditional older fuel injected 4 cylinders (As in our cars use fuel more efficiently).

3. The tire spinning problem... hell even the stoke tc has a hard timing launching in 1st. Now with a car over 200 whp it will spin the tires as soon as the turbo spools up in the first couple gears. An LSD will definitely help but I am not sure if it will really solve the problem completely. At 400 WHP I am pretty sure 2nd still would be spinning as soon as the turbo spooled up but no one really knows the answer to this it is all just speculation.

4. The emanage may have a hard time controlling timing on your MR2 (and most other cars) but on our cars we do not seem to be having an issue with timing control. I have yet to hear a problem from any turbo tc and emanage controlling timing.

 

^^ WHAT?!?!?!
A 20g can take a built 2AZFE 2.4liter into 400whp with ease.

 

Show me one dyno of a 20G on pump gas making 400 whp on any car? Sorry, it just doesn't flow enough air. 350WHP is about the limit.

The EVO 16G and 20G are great turbos for pump gas and basically make the same amount of power. At the 300WHP plus level you'd be lucky to get 15 more HP from 16G to 20G.

If you guys are making 375WHP on a 16G without cams headwork and pistons, I have to call B.S. If there are 375WHP TC's running around, where are they??? I haven't even seen a TC break 110MPH in the 1/4........ 110MPH is 300WHP.

 

Explain to me why Dre made 500awhp on a 50trim with pumpgas... 50trim is equiv. to a 20g and close in comparison.
