Hi guys!
As one of you already know it, I'm from Brazil...
Well, I'm opening this topic because I always had the desire, but not the courage ($$$) to build a Lambo-muderer Stilo Abarth. My mind blows when I think about a 1000 AWHP Stilo with that beautiful 5-cylinder music chasing some GT-R and VW-Group cars...
I still don't having the money, but someday I'll, so I'd like to discuss some parts of this projects with you.
REMEMBER: THIS PROJECT CAN BE DONE EITHER AS NEXT YEAR AS TAKE MORE OVER THAN YEARS TO GET OFF THE GROUND!!
Chapter one: the transmission
I had this wonderful idea something as two years ago because I tought that a 1000 FWHP would bunout even @ 250 km/h
Here in Brazil the best seller car is Volkswagen Gol. Mk1 Gol was launched here in 1980 and is like a simplified Mk1 Golf. From Mk2 to Mk4 (1994-2007) it's the same car, just a barely evolution from the first one. Mk5 and Mk6 are the same car and now it's like a Frankstein: The current platform is a Mk1 Gol + PQ-24 + PQ-25 hybrid.
Well, I told you all this history because as Gol is the best selling car since 1987, it's the most seen on drag racing and of course some guys did AWD ones... Normally the use Audi S2's parts such as gearbox, differentials and work the driveshaft to fit in the car. One day I was reading a performance magazine that had a AWD Gol on the cover so I tought... Why couldn't I do it on a Stilo?
Stilo's (and current Bravo's) platform (C2), according to the fair infos found on Internet, is basically a C1 (used by old Bravo/Brava/Marea/Marengo/156 and a shorter version in Alfa 147), revised (IDK how much revised, if the design is or isn't the same, if the materials are or aren't the same) and with a torsion bean rear suspension instad of that independent suspension found on C1. BTW, is C2's rear suspension better or worse than C1's?
So if Stilo kinda shares it's platform (and has the same wheelbase lenght as) with Alfa Romeo 156, could I use it's parts (gearbox, differentials, driveshaft and rear suspension) to build an AWD? Of course I would order forged gears and so, but would 156's basic AWD system fit to Stilo?
Chapter two: the engine
Of course I wanna keep the 2.4 20V 5-cylinder. But there's the beggining of another very complicated part... If I want 1000 AWHP, I'll probably have to have something as 1300 BHP to be optimistic. So of course I'll need special oredered forged sleeves, special ordered block rainforcements and all the other items (such as pistons, rods and crankshaft) will have to be specially made for my engine.
The question is: even with all these rainforcements, will the block handle this big amount of power and torque (that probably will be around 1,500 nm)?
About this 5-cylinder family, there are some questions that I'd like to know...
Is there some difference between the 2.0 20V, 2.0 20V Turbo, 2.4 20V and 2.4 JTD blocks? Height, materials, resistence, design... Is there some difference? What's the best for me to use?
About the rods... I know that the 2.0's (N/A and Turbo) ones are 145 mm long. Turbo ones are more resistent, but as I'm gonna swap them, it doesn't matter! What's the lenght of 2.4's and JTD's ones? Is there another difference?
As I will use the best block fitted to the best rod and my crankshaft will be specialy ordered what would be a great lenght? 2.0's 75.65 mm, 2.4's 90.4 mm or a special size? Remembering that my car will run with high boost (more than 50 psig for sure) and will rev high (9,000-10,000 rpm).
Chapter three: the suspension
It's certain that the rear suspension HAVE to be replaced. The point is: should I use 156's, should I order a Three Link or should I order a four link?
Is the front McPherson suspension good enough or it's much better to build a Double-A?
Of course that if the suspensions are new, pre-built coilovers such as Bilstein's ones won't fit perfectely, but as the company can build a enterily new suspension, they can make a B6 Ride Control fit!
Chapther four: chassis
Now we are in trouble. Of course with such high output we have to take care of the chassis or it will crack!!
I know about UltraRacing, a Malay company that sell front and rear lower braces and front strut bar to Stilo.
But that's too little for a car with these performance values. It would be very great to build a roll cage, but I want leave the rear seat there and a roll cage makes the courtain Airbags unefective.
So could UltraRacing products + subframe connectors + torque boexes + bracing + stitch welding replace the roll cage or this is even the best way and justifies the loss of airbags? I'm still trying to maintain the rear seat.
REMEMBER: THIS PROJECT CAN BE DONE EITHER AS NEXT YEAR AS TAKE MORE OVER THAN YEARS TO GET OFF THE GROUND!!
Cheers!!
