Hello everybody,

My Scoupe is stock and I would like to get more power to it. Only mod (that I know) is pipecross air filter.

My outlet is stock and the pipe from outlet to catalysator is 1.75" and from catalysator to end 2" with one Simons muffler.

I rememberd that Garrett T15 could go as far as 160bhp so and the the fuel up to 180bhp. So I think the 160bhp would be the most reasonable decision (when thinking the money is issue).

Can the exhaust outlet/pipe to 160bhp?


And now the question, tell me everything I need to do to get some power :amen:

Get a Garret T2 or T2.5 i would rather get the T2.5 because u will get bored of the T2 pretty quick you will probably have to get a new Down pipe made?(i dont know cos i use Mitsubishi turbo's)

Increase your Feul pressure and get a Intercooler. then get your airfeul ratio's check out. then u will know how much you can boost..

Being honest.....forget it!.

The n.a. Scoupe & the Turbo cars are SOOO different!.

All you can do with a n.a. Scoupe is basically IHE.......intake, headers & exhaust.

A cold air induction kit is fine, as is a mandrel-bent cat-back exhaust system.....(mine cost £340 about 6 years ago!).....these will give you an extra 10/12 b.h.p. on an n.a.car.

Headers will cost more than the value of the car.......& will only take the power-gain up to around 15 b.h.p. (after you`ve done the 2 previously-mentioned mods.!).

Remember, the last Mk. II Scoupes are at least 12 years old now & are priced accordingly!!.
Absolutely perfect Turbo cars might just attract some interest if the mileage is under 80K., but anything less than this will attract no attention from buyers.......& in the U.K. at least, you will have to pay a scrapper to take them away!.

Sorry to be realistic, but my advice would be to save your money, run your car into the ground & then buy something more modern.
This is just what I will be doing in a few month`s time........which is heart-breaking as my car is perfect & has never `missed a beat` in almost 9 years of ownership!.

Cheers,
Nick. :whistling:

He's driving a turbo instead of N/A. ;)

Topini,

I agree with Valkyrie. I have been reading your posts on modifying this Scoupe for months now. Your project planning is taking a long time.

You should always determine if you put $4,000 or Finnish equivalent into a car, it better be worth that much more if you were to sell it right away. If the car will not be worth $4,000 more (or Finnish equivalent) then just buy a Scoupe turbo and get a guaranteed working product.

In the U.S. the price of a used 2001 Corvette is now $20K. If someone is talking about modifying a 2003-2007 Tiburon and spending $4K to $7K, I tell them to go buy the Corvette. They will not get their investment back for the cost of those modifications on a Tiburon.

My Apoligies, i thought he already had a SCOUPE TURBO!!! LOL\

Rather just buy a Scoupe Turbo or Take your Scoupe and Drop in a 3sgte Or 4agze they are the best bang for buck at the moment!!!

Yeap, I'm in the army now, so I don't have much of free time so that's why my project is taking a long time. And in Finland 2001 Corvette is a little more expensive than 20000$.
And I love my car, i'm planning to keep it as long as possible.
:57:

so does this guy actually drive an MVTi or not?

Yes he does, It looks like a little chaos came to this topic :beer:

in its profile is GT ,mvti so i guess turbo

Yes, so i'm finally planing to change my turbo to a T25. So what kind of other mods are needed?

My exhaust is 1.75". And T25 original boost is 0.7bar. What about the intercooler, is the one that comes from 200sx too small? I could get one for free...

For example, if I put T25 with 0.7bar and 200sx intercooler, does engine get enough fuel? How much power would i get with these mods? Is the exhaust pipe too small; it's pretty new, so it would be shame if it is too small.

You are in a Real Touch Place right now. what i would do is Increase your fuel pressure to 3.5 bars(then atleasy you will be safe till 1 bar) fitt a 200sx or custom cooler(any cooler is better than no cooler)(provided the intercooler doesnt have any leaks)

if the exhuast is brand new cut out 1 box!

How much power? well More than what the T1.5 would give you. u must get a New boost Gauge so yoi can see exactly how much your boosting!

When does LIMP mode come in again? I never really had a Problem with LIMP mode plus that was like 2 years ago.

anmyway keep us informed!

NB: WHat Octane fuel do you have in you country?

i have the same problem, i am just about to put my mvti on the road, my plans r a full stainless steel exhaust system (3" pipe straight thro), astra turbo diesel intercooler and a T25-T28 turbo, and a boost controller, wat kind of power will i get out of the mvti after all that? and any other cheapish ways of addin more power will be well appreciated

It all Depends what you gonna Boost? what is the Octane of your pump gas? 95?

yea, we got a choice of octane 95 or 97

Soundz Good!

so wat type of bhp will i be lookin at with those mods i noted?

160/180bhp
200bhp will be AWSOME!

I hit 144kw and 288nm @ 1.2 bar with relative Ease. after that is where the NIGHTmare begin's

i have no idea about kw and nm lol it all just mumbo jumbo to me that side of things is lol
