duc_drconcept Posted March 30, 2015 Report Share Posted March 30, 2015 You read the title correctly we are swapping a Infiniti q45 into a roadster at dr-concept.com first test fitment super tight fitment so we are making more room Engine sits much better now but the gear box is in the way and the chassis is too narrow to fit an alternator. 3 Quote Link to comment
Swedishcadillac Posted March 31, 2015 Report Share Posted March 31, 2015 I saw the KA swapped 411 wagon on Instagram you guys did... Also heard you swapped 240SX front disks onto the same wagon, would love to see pics of that. ^^^^ just saw the suspension upgrade over on IG definitely watching this 1 Quote Link to comment

petercscherer Posted March 31, 2015 Report Share Posted March 31, 2015 I'd like to hear the logic behind the engine choice... I applaud your enthusiasm and abilities, but why would you TOTALLY compromise the purpose of the Datsun Roadster? The idea is that it is a light, nimble, and "peppy" car for light motoring. Tossing a VERY heavy q45 V8 will totally change the handling and drive-ability of the car. I can understand swapping in a SR20DE, a KA24DE, or a CA18DE, because they are all rather light engines that still can put out more than enough horsepower for a car the size of the Roadster. ~Confused...

We use stock 240sx rotors, calipers, and a custom adapter bracket made in house. I still have the CAD file save if anyone is thinking about doing the same setup. The 240sx rotor will have to be bore out in the center to accommodate the 411 original hubs and notching the stock 411 upper control arm because the brake caliper will hit.

Yes you are correct. We thought about this long hard and should have told the customer to go with an sr20det but people have already done this and even a ls1 engine. Who want to see another similar swaps....not us. So we decided to chop the front chassis off and build a new one from scratch using all the 240sx suspension. 3 Quote Link to comment
mklotz70 Posted March 31, 2015 Report Share Posted March 31, 2015 On the 411 swap......the spacer you mentioned.....was that to push the hub out or did it go between the bracket and caliper? Quote Link to comment

duc_drconcept Posted April 21, 2015 Author Report Share Posted April 21, 2015 Keeping the leaf springs out back, or? No we will upgrade the rear end after we get the engine running. sorry for the late updates, i had to finished up another project we had at the shop here it is: ok enough of the 510 and back to the roadster. I got the suspension and steering rack mounted to check the fitment and everything so far seems to be on track. Customer is ordering the coilovers so the stock 240sx struts we be removed. Next step is to mount the fenders and the hood. 2 Quote Link to comment
