Hello and welcome to the forum. The MRS4 uses a 180 size motor as stock. If you are looking for something larger, you can either go with a MRS4 "modified", a stock Losi mini-T (or baja) motor, or change the mounting plate to use a larger 300 size like the Orion Bigblock. It would be helpful to know what batteries you are currently using. One upgrade that is relatively inexpensive would be using 1400-1500 Mah NiMh cells. A 6-cell pack would would work directly with any "stock" electronics and motor, and would give you a noticeable improvement....Please post what motor, battery, and electronics you are using, and we'll be glad to help.
Again, welcome to the site.
If it don't fit, force it...If it breaks, it needed replacing anyway.

The HPI 45T mod motor drops right into the stock MRS4 and makes a big difference. If you want to use the 4-cell AA stock battery holder then get some new 2650mAh NiMH cells from Staples. They are under $20 for a four pack here.

Going to a Speed 300 motor is another option but you will need a new motor plate and the car must be run at the 150mm setting only. Finding motor plates is getting harder these days but you can try eBay.
