Superlite Roadster

I like that drawing alot. I'm thinking about a T Rex. But this looks cool too. If you don't mind, how much? And are there engine choices or is the 197 HP Si one it?

 

Not bad for under 20k.

Concidering the Atom cost thousands more, the GTM is in Corvette price range and the Ultima is well out of most peoples bouget not a bad price at all.

I would use an S2000 engine rather than an SI power plant.

 

You made a great choice in a well-engineered fun car.

Made by a top-notch company. Puts the majority of kit builders to shame.

Pretty good pricing. I have some thinking to do........

 

You can really mod those K20's to put down some impressive numbers.

 

Thanks for the kind words guys,
Hey BT we are looking forward to having you here....bring your cheque book you may want to add to your collection....

 

Yep mine made 221whp with bolt ons and KPro (Engine management)
You picked the best Naturally aspirated 4cyl (along with the F20C). I would skip the drivetrain from the Si, its drive by wire and the ecu cannot be used with KPro. If your looking to buy a drivetrain I will suggest talking to Steve at www.hmotorsonline.com and get a Japanese drivetrain. That K20 has a half point more compression, an LSD and slightly shorter 4th-6th gears. Before you do any sort of track driving you will need to get a baffled oil pan, with the stock one on high G corners oil sloshes away from the pickup causing the engine to starve of oil.

www.k20a.org is where I recommend you sign up, site is a wealth of knowledge for the K-series.

 

Maybe you should have gotten the K20a (Civic type-R) motor instead. 220hp.



Congrats either way

 

Sweet! It looks great.

We'll definitely need videos once it's done.

This is RWD though, correct?

 

Or an Accusump which can pre-pressurise the oil passages before start up.

 

Oh yes.



BT, do you know what it will weigh with the engine appx?

I'm comparing with a T Rex....

 

Neat car I know the Atom 2 will be much like this and street legal in the states

will this be street legal as well or track only?

 

You're really making me tempted to sell my car and buy a beater and this.

Nah, I can't do it. Some day though.

 

Nice! I was wondering as I saw no lights or signals on her...kind of the same problem as registering a Radical SR5 for the street here

 

Bill, where are they building them?

 

Michigan I think.

 

You are going to need to get the reflash, how are you going to run the ecu? Its my understanding that without the full ignition and key from the donor vehicle you cannot run the motor using that ecu. What you need to do is throw away the drive by wire throttle body, get an adaptor for the RBC intake manifold that came with the motor (the oem best manifold) that allows you to run a cable driven throttle body and iirc you use the RSX or JDM integra wiring harness and KPro. You will need to modify one plug on it for the new style electronic speed sensor. Its best if you look on K20a.org they have all the info there. To be honest few people use the 06+ Si full drivetrain so I cant remember 100% whats needed. With the common bolt ons you will be at around 205-210whp add a blower running 8 Psi and you should be seeing just over 300hp. I wouldnt even bother with the blower. 220whp with such short gearing in a 1300lb car is going to be fast. With that power my car had a trap speed of 109.7x mph, now imagine that in a car weighing 800lbs (40%) less. I have never heard of the intermediary that your talking about. The K-series engines are very sensitive to oil pressure etc, they need lots of oil pressure at low rpm and for IVTEC to activate, even running an external oil filter or using thicker oil can cause a big drop in oil pressure. With no baffle in the factory pan what happens is oil moves up the timing cover side of the motor away from the oil pick up. This has led to quite a few Euro track cars losing engines so I would def recommend upgrading the oiling system... its the weak link of the K-series, along with the timing chain/tensioner. The oil pump tends to cavitate when revs are raised close to 9000rpm. Like I said above the motor needs lots of oil pressure so to compensate Honda runs the pump at 1.6 times the engine speed, at 9000rpm the pump is running 14000rpm+. Thankfully all these issues can be addressed.

 

Yes, right in the greater Detroit area. I think they have direct access to materials and engineering related to the auto industry
that other kit car makers can't match.
