Engine swaps are not legal unless they are of the same type, same year or newer. Basically it's illegal to swap motors, however there are state allowances that will allow for it - Street rod title brand, experimental, test vehicles. Rich of Daft has a LS swapped 240 with is Cali legal, but its branded as experimental.
Cali supersedes federal law beyond any state, but if your craft you can pull it off.
However there used to be a carb approved turbo kit for the KA24 from garrett. If motivated enough you could get the paperwork in order to do this.

ENGINE SWITCHING FACT SHEET
UNITED STATES ENVIRONMENTAL PROTECTION AGENCY WASHINGTON, D.C. 20460
March 13, 1991
OFFICE OF AIR AND RADIATION
Pursuant to frequent requests for information received by the U.S. Environmental Protection Agency
(EPA) regarding the legality and effects of engine switching, this document will summarize federal
law and policy pertaining to this matter, and will discuss other related issues.
A. Federal Law
The federal tampering prohibition is contained in section 203(a)(3) of the Clean Air Act (Act), 42
U.S.C. 7522(a)(3). Section 203(a)(3)(A) of the Act prohibits any person from removing or rendering
inoperative any emission control device or element of design installed on or in a motor vehicle or
motor vehicle engine prior to its sale and delivery to an ultimate purchaser and prohibits any
person from knowingly removing or rendering inoperative any such device or element of design after
such sale and delivery, and the causing thereof. The maximum civil penalty for a violation of this
section by a manufacturer or dealer is $25,000; for any other person, $2,500. Section 203(a)(3)(B)
of the Act prohibits any person from manufacturing or selling, or offering to sell, or installing,
any part or component intended for use with, or as part of, any motor vehicle or motor vehicle
engine where a principal effect of the part or component is to bypass, defeat, or render
inoperative any device or element of design installed on or in a motor vehicle or motor vehicle
engine, and where the person knows or should know that such part or component is being offered for
sale or is being installed for such use. The maximum civil penalty for a violation of this section
is $2,500.
EPA received many questions regarding the application of this law to a situation where one engine
is removed from a vehicle and another engine is installed in its place. EPA's policy regarding
"engine switching" is covered under the provisions of Mobile Source Enforcement Memorandum No. lA
(Attachment 1). This policy states that EPA will not consider any modification to a "certified
configuration" to be a violation of federal law if there is a reasonable basis for knowing that
emissions are not adversely affected. In many cases, proper emission testing according to the
Federal Test
Procedure would be necessary to make this determination.
A "certified configuration" is an engine or engine chassis design which has been "certified"
(approved) by EPA prior to the production of vehicles with that design. Generally, the manufacturer
submits an application for certification of the designs of each engine or vehicle it proposes to
manufacture prior to production. The application includes design requirements for all emission
related parts, engine calibrations, and other design parameters for each different type of engine
(in heavy-duty vehicles), or engine chassis combination (in light-duty vehicles). EPA then
"certifies" each acceptable design for use, in vehicles of the upcoming model year.
For light-duty vehicles, installation of a light-duty eng~ne into a different light-duty vehicle by
any person would be considered tampering unless the resulting vehicle is identical (with regard to
all emission related parts, engine design parameters, and engine calibrations) to a certified
configuration of the same or newer model year as the vehicle chassis, or if there is a reasonable
basis for knowing that emissions are not adversely affected as described in Memo 1A. The
appropriate source for technical information regarding the certified configuration of a vehicle of
a particular model year is the vehicle manufacturer.
For heavy-duty vehicles, the resulting vehicle must contain a heavy-duty engine which is identical
to a certified configura- tion of a heavy-duty engine of the same model year or newer as the year
of the installed engine. Under no circumstances, however, may a heavy-duty engine ever be installed
in a light-duty vehicle.
The most common engine replacement involves replacing a gasoline engine in a light-duty vehicle
with another gasoline engine. Another type of engine switching which commonly occurs, however,
involves diesel powered vehicles where the diesel engine is removed and replaced with a gasoline
engine. Applying the above policy, such a replacement is legal only if the resulting engine-chassis
configuration is equivalent to a certified configuration of the same model year or newer as the
chassis. If the vehicle chassis in question has been certified with gasoline, as well as diesel
engines(as is common), such a conversion could be done legally.
Another situation recently brought to EPA's attention involves the offering for sale of used
foreign-built engines. These engines are often not covered by a certified configuration for any
vehicle sold in this country. In such a case, there is no way to install such an engine legally.
EPA has recently brought enforcement actions against certain parties who have violated the
tampering prohibition by performing illegal engine switches.
It should be noted that while EPA's policy allows engine switches as long as the resulting vehicle
matches exactly to any certified configuration of the same or newer model year as the chassis,
there are some substantial practical limitations to performing such a replacement. Vehicle chassis
and engine designs of one vehicle manufacturer are very distinct from those of another, such that
it is generally not possible to put an engine into a chassis of a different manufacturer and have
it match up to a certified configuration. Therefore, practical considerations will generally limit engine switches to
installation of
another engine which was certified to be used in that same make and model (or a "twin" of that make
and model, e.g., Pontiac Grand Am and Oldsmobile Calais). In addition, converting a vehicle into a
different certified configuration is likely to be very difficult, and the cost may prove
prohibitive.
B. State Laws
Many states also have statutes or regulations prohibiting tampering in general. Most of these laws
specifically prohibit tampering by individuals. A few specifically prohibit engine switching, using
provisions similar to those stated in EPA's policy. To determine the state law in any given state,
the state's Attorney General's office should be contacted. In addition, many states have state or
local antitampering inspection programs which require a periodic inspection of vehicles in that
area, to determine the integrity of emission control systems. Many programs have established
policies for vehicles which have been engine switched. While EPA does not require these programs to
fail engine switched vehicles which are not in compliance with federal policy, the Agency does
strongly
recommend that these programs set their requirements so as to be consistent with the federal law.
State or local programs which pass illegally engine switched vehicles may mislead federally
regulated parties
into believing that engine switching is allowed by federal law.
