GM F platform(Fbody) cars, the 80's-90's Camaro and Firebird.

I want the lights from the all new Volvo S90, Both front and rear. :)

The new Renault Twingo/Smart ForFour bodies would be cool

What about some more Musclecar (Ford Gran Torino) bodies and some aftermarket wheels (American Racing Torq-Thrust, BBS RS "Turbofans")?

Twin-screw superchargers for V8's

CVT transmission and supercharger please!!

please add adjustable valve diameter and lift/duration! also DIESELS!!!!!!

Let's not forget those legendary HEMI cylinder heads, as well as the world famous Subaru and Porsche Boxer engines.......

I do hope to see DIESEL engines in later releases, theres so much untapped potential you could get from them, especially if you going for high torque figures

CAR LIST
muscle: 69 doge charger, pontiac GTO, plymouth fury, 65 mustang, buick GNX, oldsmobile 442, doge daytona/plymouth superbird, (i could go for days)

super: mclaren F1, Jaguar XJ220, RUF yellowbird, noble m400, ford gt, porsche 911 & 918 spyder, aston martin one-77, (cutting myself off here)

clasic sports: aston martin db5, chevy corvette C1-C3, mercedes 300sl, old porsche 911 & 928 (most of the ones i want are already in the game or mods)

Luxury: bentley mulsanne, rolls royce phantom, chrysler 300, cadillac 16, maybach exelero, mercedes s65 amg, (cutting myself off again)

other: ford bronco & escort, jeep wrangler (or some version of it) chevy S10/ford ranger, geo metro (we have a smart car so why not) chevy suburban, lancia Delta, vw beetle (origonal body)

More detailed valvetrain options:
Including pnumatic springs would allow the player to control the cycle of the engine (otto/atkinson) and higher revving capabilities (even if limited to nitrogen cylinder type return).
allowing valve diameter, material and grind (angle as well as number of grinds) would allow player to better control specific heat handling capacity and therefore reliabiliy (lean/diesel/high reving) characteristics.

More fuel options:
E85 (possibly with flex fuel sensor), P series fuels (flex fuel sensor required), diesel, bio-diesel, C16, hydrogen cells, battery cells.

More options to resist knock and detonation:
water/meth, electronic ignition maping

Induction: centrifugal, roots and twin screw super chargers, twin turbo options on inline engines, twin charged option for all engines but primarily 3 and 4 cylinders, chemical induction (N2O)

extras: variable displacement (balanced cylinder shutdown). Head porting: cross section, volume and flow (even if just [big, small and swirled] would allow for many more options for torque dynmaic and stratification in conjection with a swirl valve on non direct inejected fuels (eg. see 1jz-fse). twin spark systems to help with emissions. Head designs planed, semi-planed, hemispherical, semi-hemispherical.

just throwing a fre ideas out there that would really allow for many more options for power delivery, emisions compliance, fuel economy and longeivity.

Car Bodies: ford ba falcon including headlights, Ve commodore(urgh).

Wheels: as many more sets as you guys can

+1 for valve train options ie: valve size and canter

more air filter options: the 4bbl race filters should be upward velocity stacks
pod filter on the race turbo option, and i wish the manifolds would change abit more ie, croosplane/crossram like early hemis and 327 chevs had and a twin weber downdraft v8 manifold like the manaros had in the early racing days.

And a few more bonnet scoop options a larger reverse cowl, shaker?

Australian/New zealand combined demographic in tycoon ( based on New zealand import vehicle laws and Australian manufacturing and importation laws)

Single turbo option on the V engines

Supercharger adjustments when they come for positive displacement units, cfm per revelution, max boost, intercooled or non-intercooled. For centifigal units a/r size, compressor size, max boost and the currant turbo intercoolers.

Cant wait until 2017

can some one make some mk1 cortina tail lights pleas :)

1)saab's from 1999-2012 engines
2)superchargers
3)have the turbos make more than 35psi of boost
4)when the engine/parts break up if its too much power or wrong compression...it should show where the internal parts shoot through(like if a piston rips off the camshaft and it goes out through the side of the engine it should create a hole where it shot through)
4)have a option to show if the parts/engine could fit in the body of the car you created(green means it fits..red means it's too big or needs to be adjusted to fit in the body your currently using for the engine to be installed in

bugatti body pleas
