Another swap to consider is a small, lightweight V6, like the Mitsubishi MIVEC A612. However, don’t be afraid to get creative. This is a solid, safe swap that’s been done many times, and there is a lot of literature covering it. It’s an all-aluminum engine with dual overhead camshafts and can make up to 260 horsepower depending on what car it came from. It’s reportedly reliable but doesn’t handle forced induction all that well, presumably due to its 11.5:1 compression. Swapping a Toyota 2ZZ-GE inline-four from a seventh-generation Celica into the MR2 Spyder is common for owners who want 200 horsepower in a compact engine.

If the engine bay space is tight but chassis fabrication doesn’t bode well for structural rigidity, opt for a small engine that can last forever with minimal maintenance. If you’re trying to get more power out of an MR2, try and solve as many problems as you can in the process. In a 2,200-pound convertible car, chassis fabrication could impact structural rigidity. Fitting turbos onto the stock motor may present issues only resolved by dramatic chassis fabrication. RELATED: Mid-Engine Toyota MR2 Coming In 2025Įngine bay space is a problem with the MR2.
#MR2 SPYDER HOW TO#
How to give the Toyota MR2 more horsepower
#MR2 SPYDER MANUAL#
Aside from that, the only transmission worth getting for the Toyota MR2 was the 5-speed manual due to reliability issues with its sequential manual transmission. Toyota’s ZZW30 also burned oil in abundance. The engine used ceramic parts in its pre-cat system that could break apart over time and cause severe engine damage. The power was adequate for the size of the car, but the engine suffered from a substantial defect in the exhaust. Would prefer to find manufactured 5 spoke rims in the correct 6.5 and 8.5 widths.The stock third-generation MR2 came with the ZZW30, a 1.8-liter inline-four making about 140 horsepower mated only to either a 5-speed manual or sequential manual transmission. Find matching 15" rims in 6.5 and 8.5 widths? I found a place that can cut and add 2 inches to the original 5 spoke front rims, allowing the moving the stock 5 spoke 6.5 to the front.
This maintains the 30cm width difference and same less than 24 inch diameter/height of the wheel. Required is High offset rims of 33 to 40, Front 15圆.5 and rear rims 15x8.5. The problem is finding "matching" 15" rims of different widths. Matching tread wider/ upgraded performance tires I have found.
#MR2 SPYDER UPGRADE#
To upgrade the MR2 Spyer is hard to do right and not kill someone. But this only gave 10cm difference between front and rear lessening safety. Closet I could find for the stock 15圆 f and 15圆.5r rims was Yokohama s drives 195/50/15f, 205/50/15r. The only available matching tires to maintain at the very least 20cm wider in the rear were 0 zero. Upgrade keeping the offset, matching rim 15圆 and rear 15圆.5 with available matching tread tires are very limited if any. Rims are different sizes for a good reason on the MR2, like a Porsche the weight is in the back.
The diameter must stay less than 24 inches or you will ruin the cars acceleration. Do not sell larger diameter rims and tires.
#MR2 SPYDER DRIVER#
DO NOT SELL 4 of the same size rims and tires for a MR2 spyder, you will make the car more prone to snapping around on a unsuspecting driver in a corner. Toyota did this because the car could "snap" around on people in corners, so for safety they widened the rear tires and kept the fronts at 185cm. Starting in 2003 Toyota went further by going to a 16x7 inch rim in the rear and a 215/50/16, taking the offset to 30cm between front and rear wheels. The 20cm was even found to not be enough difference. This 20cm width difference must be maintained for the car to handle properly, safely. 00:18 Mr2 spyder rims are offset, i.e wider in the rear than in the front but the same diameter.
