GRP 28 or OS 28
I will be purchasing a new 28 engine for my 8ight T soon. LHS has a tuned GRP 28 with pipe and an OS 28 with Jammin pipe. Only $20 difference between the two. What are the pros and cons of the two? Things I am considering are tuneability, fuel mileage, performance, and longevity. I am Currently running an OS 21 VSPEC in my buggy and I love it. Can you use the same glow plugs in the GRP and the OS?
Thanks
