a STOCK SR has Powdered Rods and Hyperutectic pistons, altho the rods are strong, they are VERY hard and brittle, forged metal flexes a little, powdered will just break.... ive had an SR i know the issues, and one of them is revving. Stock valvetrain can not rev past 7500SAFELY no matter what anyone says. Youll start floating valves. The CA18DET V2 engine such as what i have, came with factory solid lifters and the ability to safely rev past 9000rpm, the factory redline on the V2 is 8350 and with a compression ratio of 8.8:1 factory, it will get you into boost faster than an SR... that extra 189cc you SR guys have over the SR is a mere waste of space. The reason you do not see CA's over here is because parts are so difficult to get because of its age. But if people, such as myself, understand the motor and its capabilities (rememver its only a 4cyl version of the RB) they will take the extra time to search abroad and get the right parts. The CA has everything available from lightweight cranks all the way to aftermarket intake manifolds such as the SR, and the CA is an iron block motor and STILL 50lbs lighter than an SR fully dressed =)
Not trying to be an *******, but the SR is a beginners engine. JR's is nice, your build looks amazing, i loved my SR with a passion, but theres more to be gained with doing a CA, especially the fastest CA18 powered S13 in the US... the current record is 11.29 at 123... the record WILL BE MINE in the 10s.
