This thread is cracking me up b/c everyone is saying the CA sucks but wont even bother to explain why it "suppoably" sucks, with that said it leaves to be that you guys really dont know why it sucks your just spewing garbage. Now lets get down to some facts.

The SR is not the lightest motor dont be fooled by the aluminum block crap, the SR is actually 40 lbs heavier than the CA18DET. The CA is a 1.8l as the SR is 2.0 189cc doesnt make that much of a difference. The CA head design is amazing and the SR head is garbage, SR suck in higher rpm's and will cause a problem thats called Valve Float again due to the crappy head design. Why does the SR produce 205 hp simple b/c it has a bigger turbo than the CA. After numerous people putting on SR T25 turbos on there CA's they produce the exact HP hmmm amazing huh.

Alright lets break it down price wise as well these prices wont include things to spend on such as intercooler, piping, exhaust, just parts for motor performance.
Aight my CA was $950 included everything harness, tranny, motor, turbo etc etc.
SR20 usually go for $1900-$2300 for a normal S13 red top.
That leaves me with about $1000-$1400 to spend due to the savings.
Well lets see I could spend $150 for a SR T25 and since it bolts right up to the CA manifold no problems, so thats 205 hp for the CA now hmmm for $1100 I now have the same power as the SR but with all the benefits that the CA has such as better head and block and higher revs. say I dont want the SR T25 I could go with a T3/T04E for $350 from Garrett, external wastegate $200, 550cc Injectors $200, FPR $100, Fuel pump $90, $20-$200 tuning either Rom Tune or Mega Squirt, $30 for Z32 MAF or $0 since Megasquirt uses and comes with a Map sensor, T3 manifold $179

Thats $1169-$1319 and with all that, will produce a CA with about 320-340 WHP.
so in total thats about $2000 for a CA then add in like $600 for things you need to complete the swap such as intercooler, exhaust, parts, gasket, lines, fluids, etc etc so $2600 to swap in a CA with 330whp oh yea those prices dont include clutch b/c my motor came with a Nismo Stage 2 clutch so it will handle that hp, but add another $200-$300 for clutch as well.

BTW it takes more money to produce 300+whp for a SR than a CA and its easier on the CA.

Also the stock CA's internals can handle 500whp if done properly and tuned properly, and yes its been done before numerous times. So far the record for a CA is around 750+ whp. Now tell me again why the CA sucks?
