What Engines are compatible with a 1988 Toyota MR2?

Answer 1

Two engines came from the factory for an 88 MR2. The 4AGE is the normally aspirated version of the engine. The 4AGZE is the supercharged version. Some people have installed the 4AGTE - a turbocharged version of the 4AG see www.4AGTE.com. A good reference on the 4AG series engines is available at www.club4ag.com. Others have gone as far as to modify the engine mounts and remove a piece of the firewall between the engine compartment and rear trunk to install the 3SGTE from the second generation MR2. There are companies that offer kits and specialize in this conversion. V6's have been fitted into MR2's using Toyota's 1MZ-FE and 3VZ-FE engines. A good writeup can be found at www.mr2mk1club.com/V6MR2.html And not for the faint of heart, a few have taken on the extreme challenge of shoe-horning a V8 into their MR2's. Bill Strong is on his second build of his "Toystar" an 1986 MR2 with a V8 Northstar engine from a Cadillac, see www.v8mr2.com
