My user name obviously tells you which of the 2 motor's I favor. Honestly, If you don't have a clue nor any hands on experience I strongly suggest going with an SR.
Im not an SR fan at all. I have been in the game for a long time and have boosted Ka's and associate myself with people who own boosted Ka's. One of my closest friends has had his on boost for about a year now. The car feels great and the motor is stronger then ever. Mind you, he turbo'd his current motor with 200,xxx miles on it.
Its not a walk in the park at all. He first built his setup for under $2k. As soon as he got an AFC he dyno'd 250 rwhp at 9 lbs. Thats less money then an SR swap and alot more power then a stock SR.
Btw, for those non believers...
T3 - junkyard - 100
Walbro 255 - 100
Ebay Intercooler plus piping - 300
Sr 370cc - 120
Manifold - 300
Bov - 200
Afc - 200
Hoses - Fittings - Clamps - Miscellaneous Parts - 200
Probably missing a few items but you get the idea. Im sleepy... :boring:
^^ $1500 = 250 rwhp on a Motor with 200k miles. If he bought Pistons he would still be under 2k. Now ofcourse, all the work was done by us. As time has gone by hes bought Flexalite fans, Koyo radiator, an Fpr....etc.
In other words... If you are hands on and would like to build your motor yourself go KA. If not, have a shop put an SR in your car.
No offense to Sr guys, but I see alot of kids that don't know shyt about there motor and have probably dropped a few grand into them. Thats kinda sad... :ugh:
