way to ask a question in a group that is goin to be completely biases.

CA pwr ! till i try an SR and maybe like it better !

I have never driven a CA. I hear they rev beautifully though. I love my Redtop though and she is fast as stink (by my standards). I think the only people that can answer this question are those that have experienced both.

Jon- I let you drive mine if you let me drive yours

come to indy you got a deal! and yeah the CA likes to bounce off the revlimiter if your not carefull vrroom 12348 whoops whered the rest of the rev range go? nothing like my sohc KA that would barely rev to 6k

[nrcooled]

My SR with a lightened flywheel I still feel that she really doesn't want to rev. I think it's more a t2small issue than a SR issue. Time for a turbo upgrade

Edti: I've got family in indy so next time I go up I will drop you a line and maybe we can have some JDM engine fun:blue

[SR22DET]

umm also which engine since there are both CA and SR owners in here which engine do u guys think is easier to maintain and is better for drifting so far i think the CA since u guys say its a really good rev motor thanx

[nrcooled]

Any engine is easy to maintain if you know what you are doing. I do all the work on my car and some is trial and error and some things are cut and dry. It really depends on your tools and room to work in the engine bay.

If you do your own swap then you will know what to look for in general. I paid someone to help me swap my SR. Since it is a daily driver I couldn't afford massive downtime. Had a great time doing it and it took three days;) I learned so much that weekend and it has continued to pay off.

Sr = Aluminum BlockCa = Cast Iron Block

you can do what most peole do and make you own guess to which is better. But keep in mind the CA's Cast Iron block is cast with a very flimsy iron.

[Cyberkreig]

The castiron/aluminum block thing really isnt that big of a deal to me. If you have your motor properly tuned Aluminum will hold together just fine... Course, you can always put int Castiron sleeves and not tell anyone. =-)

not to contradict anyone but doesn't the sr have ductile iron sleeves already?

[slw240sx]

i think so! both are good motors are they reall worth the money it takes to get them ? no but hell its sure is a fun swap to do and drive!

[SR22DET]

how do u gusy "PASS" smog cheks and all that crap

[nrcooled]

I have my 240 registered in Ohio (where I used to live) so I don't have to deal with inspections in Virginia. Eventually i will register it here in VA and I have a hookup lined up already.

The SR will pass emissions and I still have all of my emissions hooked up. As long as the guy isn't too hot on Nissan engines he won't know the difference during the inspection. As for living in Cali. good luck with that. Those refs don't mess around and know there stuff. Also with all the popularity that the SR has gotten it will be a red flag along with all the Honda JDM swaps.

I didnt think this was true, but i didnt know.. so i searched around and found this image

I think this shows that there are no sleeves
