Wow, what does Autech do to the S15 NA to get 200HP? That must be a fun drive, I am going to have to ask Ted for a ride at Shasta this year!

Alvin - I guess we have high tech classics? Maybe some people aren't ready for that, but I am enjoying mine to no end...As always, to each there own...TR

The Autech versions of the S15 SR20DE engine make most of their horsepower from a compression change. They run a 11.7:1 compression ratio (which you can do on the nice high-octane Japanese spec gasoline!) Of course the engine also has revised cams, one of the most beautiful stainless steel headers you have ever seen (with a 2 3/8� exhaust), sodium filled valves, a light weight flywheel, and a remapped ECU to take advantage of all the changes. Autech versions also come with the turbo’s 6-speed transmission stock.

The Autech SR20DE is a very hard engine to come by, due to it’s very limited sales in Japan. They are very expensive, and sought after…

We don’t limit our SR20DE/T swaps to just roadsters, we have Autech version SR20DE swap going into a 1991 Miata right now. I find it funny that guys are pulling Miata engines to put them into Roadsters—we are pulling Miata engines to put in SR20’s! 200 real hp in a Miata ought to wake up an otherwise capable chassis…

Michael, there is a serious business oportunity!

Import SR's, sell to Miata owners with a core, then sell the core to roadster owners with a core, then sell to roadster owners that wish to remain stock!

Hmmm...TR

With the help of TR, I am finishing up a ka24e powered 68. When I get it finished maybe TR and I can do some testing against it. Not with his SRDET but against my stock 2L.

Oh, and until you see a roadster launch while rolling at 65 with a DET you haven't seen roadster performance!

My insurer didn't ask any questions about the car for collision/liability - Are you talking about replacement value insurance, theft, etc.? If so, I don't know. Anyone? TR

I go through Grundy for collector's insurance. They never mentioned or asked about frame cutting. I'm a bit surprised that the insurance companies that specialize in customs and classics would concern themselves with frame cutting. When was the last time you saw a chopped deuce coupe or a tubbed muscle car that didn't have frame mods?

What you are referring to in insurance is not the frame cutting but the power plant under the hood. I used to sell all types of personal lines of insurance. I currently have my roadster as a collector with JT Taylor. They have 2 types of classic insurance, stock and modified. Modified does carry a higher rate. Currently my car is not modified and costs only $106 a year with no deductibles and $300 csl (combined single limit), stated value $10k. They try to keep you at 2500 miles a year (as most classic policies do) others are even more strict, like State Farm that only covers the car for parades and club functions, they state they won't cover the car if you drive it work one day.

Anyway if you don't have a classic policy look into them JC Taylor is on line as many are. Having this type of policy with a stated value over a stated value on a standard policy is about 1/4 the annual cost.

Does anyone know why Nissan did not import the SR20s to the US?

Thanks Alvin,

I was wondering about the north/south motors, not the east/west ones. I just figured that if the SR20 is the latest and greatest, the US market (always considered to be the most important market due to volume of sales) would get all of the best stuff. It could be an emissions thing, but since they came over in a couple of cars, I question that. It may be the durability thing. US market cars are used more then JDM cars due to the JDM cars being taxed exponentionally based on their age.

On the frame cutting, here is a thought to consider. If you are involved in an accident in which there is an injury or death and the other side finds out that your vehicle has had structural modifications (torching out a major chunk of the crossmember that supports the suspension) or non-certified safety related modifications (Volvo brake conversion), you could be in for an unpleasant legal battle. Engine swaps that don't cut the car and don't change the balance of the car would not be grist for that kind of ugliness, but the other mods can make for uncomfortable times.

Just some thoughts from the peanut gallery.

Sid,

The same can be said about people who leave their vehicles in poor maintance and still drive on the road and endanger others. I have never heard of a case that because a person modified the vehicle it made them more at fault for causing the accident than them having the accident anyway. When a citation is cited it is generally for the operator (person's fault) and not the vehicle.

Ok, done with the insurance crap!!!!!
