The SR20DET is not sold in the US, so IF you have a problem, no dealer or shop will have a clue what to do with it. If you want parts, you most likely have to order them from Japan and pay through the nose for shipping, then wait months to get said items you paid through the nose for. Example: Need a lower timing gear? Think the dealer can get you one? Not likely, because the dealer doesn't even have a parts listing for the engine. How about a new oil pump? Good luck.

The $2500 price looks great, but almost no one gets the swap done for less than $5000 total, so what looks to be a great deal, becomes a great pain in the *** trying to find parts to make the swap go smoothly. Then there are the issues that come with changing all the cables, belts, hoses, and high pressures lines (throttle, clutch, brake master cylinder, Air Conditioning, Power Steering) because these aren't made for that engine, they are made for the KA24DE.

Downtime: God only knows on this one...How long can you afford to have your car down? Depending on the skill of those doing the swap, figure between 2 weeks and 5 months to get the swap done by the time you wait on all the parts you will need or have them fabricated.

There are many positive points about installing a kit specifically made for the KA24 engine:

The KA24DE is a STOUT engine, it can handle 15 PSI on stock internals with fuel and ECU upgrades, and is VERY reliable.

Example: Our Stage I car has 80,000 miles on it and dyno's at 338 WHP and 342 ft/lbs of torque...no issues whatsoever, daily driver. 1/4 mile best E.T. 13.34@102.7 MPH

Our Stage II car makes 468 WHP and 473 ft/lbs of torque (more than a Z06 Corvette) on forged internals (assembled in the US and, most importantly, available here in the US).
1/4 mile best E.T. 11.91@123.8 MPH. ALSO, a daily driver.

A stock SR20DET after a swap will run high 14 to low 15 second 1/4 mile ETs, so after all the work and expense of the swap, you would have to drop in another $4000-$5000 to get into the 11s.

The SR20DET will make the same numbers the KA will, except the KA will make WAY more torque (no substitute for displacement). We don't offer a kit for the SR20DET because we honestly believe that the KA is the better engine and belongs in our cars. We favor the KA...its cheaper and easier to upgrade and can make more power…
   don't underestimate it.

A final word about our kits.
The feedback from our customers is: ”12-16 hours install time, looks like it came from Nissan on the car, and you don't have to chop your car up to do it, only MINOR modifications necessary.”
