I have to say this and I am sure you will not like it. Buying a modified car that you know nothing about and cannot recognize the mods that have been done to it was not a very bright idea. Turbos arent measured in inches to start with and there is only one set of cams worth owning (IMHO ONLY and they come from JME). Can we ask what you paid for this car? Are you able to take pictures? To make that kind of HP you would need (Ill keep going for Rich here)

Larger Turbo
Bigger injectors
MAF/MAP/Stand Alone
20 PSI or more (depending on how good the tuning is you could make it a 18PSI).
TiAL or other WG
Boost controller


It would be wise to have
EGT guage
WB02 Setup
Boost Gauge
Custom exhaust including straight pipe
Metal HG
and the list goes on and on

For us to tell you what you have is going to require pics of part or at least descriptions and unless you paid a small mint I am going to have to doubt the 390 claim. My guess it that it is much closer to 290 which is still plenty fast and kind of scary if you are coming from an NA.

i just went down stairs and took pictures of the engine, iam trying to post some them now

 

here is the back of it

 

front

 

If thats the stock afm I see, then I would doubt 390hp.

 

390 w/a stock AFM? I have serious doubts.

In any case, have fun discovering just what it is you've gotten yourself into.



Damn, Jason beat me to it.

 

just a little fyi your missing the windshield washer cap, why are the headlights outta wack?nice color though love the silver even though the original color looks to be black

 

iam trying to get closer pictures but it says they are 2 big

 

Looks like a stock AFM and if it is I am pretty sure we can eliminate 390. Can you take a shot of where the air flow meter meets the cone filter? And maybe a shot to the left of the coolant res. From there we can see if it is a stock DV etc. BTw - what color was the car originally?

Damn you both, I was distracted and you both managed to beat me to it!

On the close ups you need to resize them to like 800X600 max and lower the resolution.

Ill bet you double or nothing that a stock DV wouldnt last 1 hour in a 390HP car :>)

Hey, 10 bucks is 10 bucks. You're on. When your beast is done I've got a reasonably new DV we can put to the test! haha

Who am I kidding. You'll be finishing that car in a garage in Chicago...

 

Duuuuuuuuuuuuuuuuuuuuuuude.....


You better break out the Rennlist platinum card, man.
