2 wheels good 4 wheels better

Higashi Corp has been watching closely the development of the recently imposed oil embargo. and as such they think there is money to be made in selling compact cars: there is a problem though… they dont know how to do 4 wheels. they have beem mostlky producing motorcicles of all sorts. their plan is to employ a modified engine from one of their top of the line bikes and use it to power a small car.

the engine is a small aluminium 1000 cc DOHC I4

the most important is that is car is meant to be a small car that appeals to the young and young at heart… and 4 of its buddies

you are allowed to modify the engine slightly, number of valves and materials must be the same… 91 RON CAT mandatory

Looks like fun. I’ll play around with this after work tonight.

[necronassassin]

Sounds like fun, will try something!

What are we being judged on?

[RaduST]

is turbo allowed? what are the evaluation criteria?

are we allowed to add an aggressive exhaust and intake? Nothing says young and fun like being able to hear somebody revving 3 streets away

[Manche]

be creative… just dont make it too expensive in purchase and mantenience… young people usually aren’t filthy rich unless daddy pays, or they are some kind of rockstars… And I’ll drop this right here: remember that many rockers drove minis after becoming famous and millionaire

You can play with compression , cam profiles and reciprocating assembly materials. just leave the quality sliders alone for the engine

This is my submission for this thread…

Meet the 1975 Cancun! (Pronounced Can-coon) This feisty little Compact concept can seat 4 people, reach 160Km/h (almost!) and is easy on the fuel. Better yet, with 45Kw and rear wheel drive, this little beauty’ll make all the ladies want YOU to be their man…

See, I told you it’s the BOMB!!!

[Manche]

sweet little funmobile… this is the stuff i was looking for… remember you can swap inteake and exhaust as well

[np1993]

With a manufacturing cost of less then 8000$, 68hp, front wheel drive, a top speed of 160kmph, a 0-100 time of 11.8 and better then 31mpg US fuel mileage you can’t ask for much more fun for the money then what you get with the 1975 Kazoo H-100. With its race-y intake and sport inspired exhaust your buddies will hear you well before you pull up to the club! With a 5 speed transmission and an open diff you and your four pals, thats right four pals, can constantly do one wheel peels every time you come across a stop sign.

the 1975 kazoo H-100, fun has never been this cheap!

Ladies ant gentlemen. Oltena is proud to present you its new lightweight, sporty and economical hatchbacks, the TRS 10 and TRS 10T. The TRS 10 features a 1 liter inline 4 transversely mounted, providing 64 hp and 75 Nm of torque, enough for a 10.6 s sprint to 100 kph and a top speed of 188 kph. The engines needs less than 6l/100km (39 US mpg). The TRS 10T uses the same engine, turbocharged with a small unit in order to provide enhanced dynamics. The result: 76 hp and 96 Nm of torque. The top speed raises to 195 kph, while 0-100 kph is dealt in just 9.4 s. More important, the fuel economy figures remain the same!

Time to break a few rules here.

Having received a crate H-100 motor from the Higashi Corporation, Ardent’s engineers went to work analyzing its strengths and weaknesses. While it had a phenomenal broad torque curve, there were improvements to be made to adapt the power plant to the preferences of Ardent’s buyers.

Ardent’s performance division got involved in the redesign. They decided to change from a single carburetor to dual, but kept the sidedraft configuration originally penned by Higashi. A special crank and connecting rods were devised as a stroker kit for the existing design, compression was raised, and the camshaft was made less aggressive to bring power up in the lower band. This brought the rev limit down somewhat so the new conrods weren’t stressed too much. Power for this new 1302cc configuration rose to 79.5 HP and 72.1 ft-lb of torque. The original torque curve was preserved for the most part, and development of horsepower was very smooth.

Thus started Ardent’s captive import brand: Suzume. The 13G was the first model borne of that collaboration.

Despite the small motor, performance was still quite respectable. The Suzume 13G could reach 100km/h in 10.4 seconds, had a top speed of 185 km/h, and still managed to sip only 6.2l/100 km. Seating for 5 was standard, as was power steering and a 5-speed manual transmission. Ardent applied the same safety features on the Suzume that were found across their entire small-car lineup, including 3-point safety belts with pretensioners up front, tempered glass, door intrusion beams, and more.

A smaller, less expensive option was offered as well, using a mildly modified version of the original H-100 990cc motor. Dubbed the 10S, this model was more basic transportation. It was only available with a 4 speed motor, had narrower tires, and could barely make 160 km/h. Performance wasn’t thrilling, but despite the underpowered engine it still managed 6.30l/100 km.

(tl;dr: Yes, I stroked the motor on the 13G. It seemed the right thing to do. Shouldn’t be illegal since Manche said reciprocating parts could be changed, and technically that’s what most stroker kits are.)

Numeric stats for comparison (10S/13G)…
Tameness: 49.6/44.1
Sportiness: 13.9/22.8
Comfort: 17.2/16.3
Prestige: 9.0/10.6
Safety: 16.4/16.7
Total cost: 5887.04/6597.14
Production units: 123.55/130.09

Edit:

Added the Suzume 10S, as well as total cost and production units.

Since everybody seems to be posting the stats of their cars, I thought I’d follow suit and do the same.
And so, without further ado, I present to you: the Higashi Sprint

The Higashi Sprint 1000 is a small, cheap and peppy little sports coupé, powered by the Higashi 1-litre inline four. Making nearly 60 horsepower at 6900 rpm it propels the car from 0 to 62 mph in 12.5 seconds and keeps the car going to 100 mph, yet still manages to keep the fuel consumption to a healthy 33 US MPG. The car has double wishbone suspension front and rear, disc brakes on all four wheels as well as 6.5-inch wide sports tyres monted to stylish 13-inch alloy wheels. All of this can be had for a production cost of less than $5700.

The Higashi Sprint 1000 Turbo is the more powerful sibling of the Sprint 1000, and uses the same engine plus the addition of a state-of-the-art intercooled turbocharger system. This boosts power to a whopping 84 horsepower, enough to manage the 0-62 mph sprint in less than 10 seconds and increase the top speed by another 7 mph. To handle the extra power the wheels have been widened by more than half an inch, and the car has been equipped with an advanced aerodynamics kit, which keeps the car planted on the road at high speeds. Despite this addition of power, the car still manages an excellent 32 MPG, while still not exceeding a production cost of $6400.

I like it it does look like it belongs to the era

I cannot see any drama here; your premise reads within the rules to me

This has real life precedent as well; Honda changed carbs, tune and capacity on their early 'bike engines when they used them in their first cars.

I would wait until the first facelift to introduce the “stroker” then the hype of a new engine’ll sell more cars!
