Default Mass rules on engine swaps? Anyone know?

Hi guys,

Anyone know what the Massachusetts rules are on engine swaps. I'm more concerned with the inspections.

By engine swaps I mean stuffing a big engine like say an LS1 motor into say an RX7, Miata or 240sx and such . I have been itching to build something like this for a while. (drooling over the thought of building a late model RX7 with a huge cammed LS motor.... sounding like the beginning of Van Halens Hot for teacher )

But with Mass being so screwed up when it comes to things like this not sure if this is possible in our crappy state....just wondering if anyone has any info.

Thanks

Jay

I'll let you know, my friend is in the process of buying a 2000 2door 2wd S10 Blazer with a single turbo built 6.0L LS motor in it. See what happens when he goes for a sticker.

if its an OBD1 car you'll be all set, I think its all safety and visual for pre OBD2 cars now. But if its OBD2 they just plug it in and go by the computer to let it know if there are any problems. But what I'm not sure of is if the machine will notice the computer doesn't match the car.

Or you can just get a rejection sticker and drive it anyways. I'm assuming it would be a summer car, so, just get a new rejection sticker every month. If it fails for emissions and not safety I think you can drive for 3 months... not 100% sure on that though.

Maybe someone knows more.... anyone?

Maybe Pete will chime in. He's built at least 2 RX7's with LSx swaps.

The SEMA bill passed in November, so the registry is working out the details for us kit car guys. I don't know if you can use the same regs for a swapped car or not.

The ecu may not store a vin but if it does it doesn't need to match the car. The registration and past sticker needs to match the car though. I don't know how that would work if the ecu is from another make /model. To my knowledge that shouldn't matter but I could be wrong on that

My understanding is that if the motor you swap into your car is newer than the car, then the car must comply with the emission regulations for the year that the motor was built, however if the car is newer than the motor, the car is still suppose to comply with the same emission regulations of the year the car was built.

In practice I don't know how many inspection centers are actually going to chase down the VIN from the motor to determine what year the emission standards should be for though.

If it is an obviously "non-standard" type of swap then my guess is the inspector is going to spend the bulk of their "visual inspection" time just verifying that everything emissions related is properly connected.

Like Jack said, I've done two LS1 RX7's. They're a blast. I just picked up an RX8 for another swap. '95 and older (pre-OBD2) are emissions exempt in MA. Its just a safety inspection.

If you have a '96 or newer chassis, you must maintain OBD2 functions and pass the plug in test. You're also limited to using an engine that is the same year or newer than the chassis. They will do a visual check for cats as well, just like any other emissions test.

Sweet! Are you the guy who went to the Broke Status VW show with an LS1 Rx7? (I see you have a VW also) I almost went with my turbo'd Megasquirted VW Meyers Manx buggy, but decided not to at the last moment. (its not much of an aircooled show) Then all my friends that went told me about a sweet LS Rx7 that was there....dammit!

Anyway, so the inspection stations dont give you any hard time with a V8 rumbling away in there? I'm tempted to do the miata, as I think that would be the ultimate sleeper, but I dont think they look as good as the RX7s.

Any pics/writeups of your past builds?

Thanks

Jay

I didn't do a build thread on the second one, but the FS ad has a good description of the parts.

And the RX8:





I'm in no rush to start working on the RX8. I have my GTi to drive every day and the S2000 that I share with my brother as a track car. The RX8 is half his as well.

Its registered and insured, he's on his way to NY right now to get it. I'll prob be going for a ride and maybe driving it tomorrow.

I've seen a video of it beating a mustang that runs 10.2, and it was spinning the tires while doing it... should be interesting.

No, I never went to the Broke Status show. I make a rare appearance at the Millbury meets every once in a while though. There aren't many other V8 RX7s around. Theres someone with an FC near the cape and Taylor (I forget his name on Nasioc) thats in the middle of a swap.

I had trouble with the first one passing inspection because they hadn't changed the law yet. The second one, the inspector said the exhaust was a little loud, but he'd let it slide. He didn't open the hood and I didn't tell him about the swap until after I had my sticker.

There are a bunch of other builds on norotors.com The guys over there come from all different automotive backgrounds. 50/50 import/domestic. Its one of the better small forums around for tech stuff.
