View Full Version : dp2 engine choices
since the dp2 will accommodate a very wide variety of engines, i'm curious to see what some of the favorites out there are. the initial installation kits are planned for the following:
- Chevy LS series with Mendeola SDR or Porsche G50 gearbox, longitudinal, 400-600hp
- Honda K20A with Honda gearbox, transverse, 220-300hp
- Ford Duratec with Ford gearbox, transverse, 180-300hp
- Honda K20A or Ford Duratec with Hewland JFR sequential gearbox, longitudinal, 180-300 hp.
any other favorites?

How could you go past the well proven Mitsu 4G63T - is there a better 300hp+ for buck engine around?

if i'm not mistaken these are somewhat older motors and given the price point of the dp2 and its mission in life (trackday car that can be streetable, not the other way around), i would generally expect people to go with newer powerplants and in many cases brand-new 'crate' motors like the LS. but perhaps i'm off on this?
generally if an LS and a K20 fit, just about anything else will fit also.

My vote would be the Duratec out of your list.
They are plentiful and cheaper than the Honda for similar power. The matching transverse gearbox also.

Be careful w/ crate motors if it is to be used on the street. W/ a "used" motor, you have a car whose emission guidlines must be met. On a "new" Crate motor, there would be no guidlines, and you are completely @ the inspectors mercy.
Been down that road w/ a LS2 in a Porsche 944:D:coolnana: Ended up swapping a Camaro LS1 in just to please the smog Nazi's (California Air Research Board) and then swapping the LS2 for that. HUGE PITA!:thumbdown2:

I do think your off on that, its a hell of an engine first ones (Evo specific) had 250hp and since 1996 no less than 280hp+ STANDARD.
Made until 2007 by the way.

Type 4G63T into Google, utter urban legends are 4G63T's and some of the power levels for the price are staggering and you can't kill them.
The400, sold through Ralliart UK, produces 302.13 kW (405.2 hp) from its 2.0 L 4G63 engine, the result of special modifications by United Kingdom tuning firms Rampage Tuning, Owen Developments, and Flow Race Engines. At 202.9 hp (151.3 kW) per litre, it has one of the highest specific outputs per litre of any roadcar engine. With a curb weight of 3200 lb (1450 kg), it achieves 0-60 mph in 3.5 seconds, 0-100 mph in 9.1 seconds, 1/4 mile in 12.1 seconds at 118 mph (190 km/h), and a top speed of 176 mph (283km/h)

thanks, it's good info.
as i've mentioned our emphasis is on track use but the more information we can give customers wishing to drive on the street, the better. but it is still their decision at the end of the day, when it comes to street use we can only sell the chassis and not the drivetrain.

In California, if your "kit car" looks like something that's been built before (Cobra, Speedster, Lotus 7) it gets titled/registered under the year the vehicle it was based on was built, and needs to satisfy emissions from that year. If it is a totally unique design, it can have any motor it wants and must satisfy emissions requirements for 1965, or some similar emissions-easy year. However, only 500 cars are allowed the special build status per year. First come, first served. After 500 people have registered their "special" cars, the emissions standards of the current year are used for any remaining builds.
To me, the weight of the vehicle helps define the engine type. If you hold it under 1,000lbs, a 1,000 - 1,400cc motorcycle motor seems hard to beat.

Cord do you know if/how quickly the '500' is filled?
Is there 500 people lined up at the gate on the 1st of January? (not literally of course).

from what i understand (from someone who's been through the process), throughout the state there are in fact people lined up at their DMV branches on the first business day of january and the 500 spots go within the first hour or less.

Ok, thanks :-)
4G63 is a good motor but a Nissan SR20DET whips its ass for power and weight

How do you figure that?
I have handled both engines, and I mean with my own hands, and there is little difference in weight and why should there be? Spec is very similar and they are both sound engines.
Once upon a time in standard form the Nissan had the edge as in the 250hp Pulsar GTR-i but that was a long time ago whereas for many years now the Evo has had minimum 280hp and suspected to have more. So if your budget is to buy a stock runner you'll be ahead with the Evo unit.
As a hot up prospect for either it's simply how many bucks you got??
sr20's aluminium, 63's cast iron block,lots of sr20's make 500+ hp, also just starting on rear engine duratec (lic reg's) sr20 still gets my vote

Aluminium block has nothing to do with an engine being lighter, especially when its a mass production engine and many a mass production cast iron block is lighter - if you want an example (as most do), Audi's 5 cylinder cast iron block is 22 lbs lighter than it's later aluminium replacement. GM Holden's 3.3L Red 6 with not only cast iron block but also head is the lightest mass production il 6 ever made.
Cast iron blocks need very little ribbing while aluminium blocks not only require major ribbing but usually a heavy cast aluminium sump as well for engine rigidity.
Lots of engines make 500hp and lots of their owners spend a lot of money to get there, theres no free ride including Nissan or a Mitsubishi.
May interest you to know that the most powerful F1 engine ever, BMW's 1200 + hp 1500cc turbo inline 4cyl was cast iron block and later Renault used cast iron for their 1100hp qualifying engine for strength but aluminum for the race because of cooling benefits for the V6 turbo.
sr20det is around 130 lbs lighter than 4g63t its replacement the 4b11t is a alloy motor

SR20DET is not 130 lbs lighter than a 4G63T and manufacturers go to aluminium for reasons other than weight.
I won't respond again because I feel we have rudely taken up too much of DP cars space - my apologies for that.
If you wish to continue debate there is an engine sub forum here.
ultimately the most convincing argument is not to tell but to show - build a car, put your favorite engine in it and show the world how light/powerful/cheap it really is. the dp2 will accept either of the above and much more :)
Correct. Old race car saying...........When the flag drops the bullshit stops, 1 racing 1 in production.

Any news on the DP2? It looks awesome.
I'm a big fan of the 4G63 (I drive an Evo IX), but I like the idea of a Chevy LS7 in an exocar weighing 1600 lbs. I also like how the DP2 has a full cage around the cockpit.

After California's 500 SPCNS permits are issued, you can't get another for the rest of the year. It means that not only the car would have to meet current emissions, it would also have to meet crash-worthiness, bumper height, airbags, MPG, ABS, ...and a partridge in a pear tree.

no it just means you have to wait another year and try again. that's the cost of living in california (one of many). every kit/specialty manufacturer is faced with this problem because not a single one can meet all current-year regulations.

Agreed- that's what I meant by "for the rest of the year". Thanks for the clarification.

There is a SEMA-sponsored bill in the house to increase the number of specialty vehicles from 500 to 750.

we are in fact using the e-rod kit in the D2. it's a great package for this application. with it the D2 will be able to register as 'constructed vehicle' or kit car in majority of states. each state however may have additional requirements that may need to be met. the D2 will have headlights at 24" from ground, safety glass windshield with wipers and 3-point seatbelts. this may or may not be sufficient depending on local regulations.
