It’s a lot easier to get an SR to make 300whp and cheaper.
Trust me, if the price ratio for an SR making 300whp was the same as going LS1…at least 30 people here would already have LS swapped S13s.
The work invovled is a lot…and unless you have all the tools and can do the labour yourself, it will cost you at LEAST $8000 to have that thing running in your car.
SR swap is $3000…add a T28, 550cc, and ems and you’ll be 300whp but obviously it is not as awesome as an LS swap.
