I think you guys are being silly. Whatever...last i checked far more manufacturers have parts available for the SR20 than for our blocks, regardless of whether they are "JDM" or even usdm.

I personally wouldn't want an LS1 in something i was going to be attempting to daily drive. I think the SR block is interesting because it allows a very moderate tune that is capable and gotten for relatively cheap. Sure if you factor the actual cost of trying to get a SR it doesn't make sense, but if you had a cheap miata shell around and already had the SR motor, i don't see why it wouldn't be worth your time just to see what it could do.

For me looking at it. I see stronger transmission, stronger block, unique, and a lot of potential. When was the last time you saw on a normal basis 450 hp on a Miata motor? or how about 700 hp?

I don't care what Hello Kitty sells for our blocks.

lmfao....
i get why you would want to do it...but to me it just doesnt make sense
if you are going to go to 450-700 hp, i dont care what 4cyl. it is its gonna cost you an arm and a leg...why not save money and stick with what you have...unless you are just so deep into JDM and drifting where the only recognised names are sr20 rb26 jz b16 and b18
so why not drop the b18 in there, there are a shitload of sellers for them all over fleabay etc...

or why not a ka24? more displacement and a hell of a lot cheaper. The only reason to swap another motor into a miata would be for greater displacement right (if you can't work out other problems then you don't need to be swapping anything to begin with)? so an ls1 would be a monster compared to a lil-ole 2.0 liter.

no LSx no care

lol chrome roll cage

:rofl: who wears rubber gloves when working on their car?

one might wonder why there's such a high demand for SR20 parts :D

uhhh.. apparently chics in Lexington, SC still likes dudes with dirty nails? i see plenty of mechanics wearing nitrile gloves (the crap he's wearing rips easily). they even sell nitrile gloves at costco for cheap now.

so to answer your Q: i wear gloves when working on my car(s) so 1) i can boink the gf 2) go to the opera 3) eat sushi with my fingers, right after lowering the jack.

anywho, stop the haterade.

what MX_Eva said +1. much rather have this than the LS1. in fact, in my hands right now is a container from Yokohama with a coupla SR20DE-T's. Invoice value is about JPY50,000 including tranny. SR swap into 10AE would be a fabulous 3rd car.

I wanna see dyno numbers. If it's not more than 300whp, that swap was completely pointless.

I don't see why it has to run over 300, not that I don't think it's easily achieved. If I was going to use a SR miata, i wouldn't want 300 hp for daily driving. Granted I might be inclined to have different tunes so that I could rip it on the dyno or beat it at the track, however i think you would see much greater reliability from the SR that our motors considering they make 200 hp stock.

SR aside, if I was to go with one of the "240 swap" motors. I would choose the Ca18DET. I think it matches the nature of the Miata motor more as a high rev stout block, only issue being it's Iron and apparently has a weaker head gasket than its bretheren.

Let me be more simplistic. People can take their SR20s, JZwhatevers and whatever pointless swaps and bullshit is popular in ------ NOPI/Drift culture and blow it out their asses. Nobody else cares.

i've worn the thick blue ones, but not the medical ones :td:

i still prefer no gloves though, the feeling of hot oil running down your hand is one of a kind

:rly:
because Al Hounos says so

Why the fuck does this subject always get everyone so bent out of shape? You think there is something better to do or swap in???? Do it then. Why is anything outside the box always so hated upon here?

cool

I think that's precisely why some take issue with it: it's really not outside of the box.

You're swapping one turbo-4 for another...from another manufacturer. It's just kinda silly. The Miata aftermarket is pretty healthy.

That being said, if you're doing it just to be a little (but not a lot) different and/or you grew up working on Nissans, then that's great! Who knows, maybe the Miata motor blew up and the guy happened to know of an ultra-cheap SR20 sitting around. In that case...it's a foregone conclusion.

I don't think it's "engine swap hate", I thinks "sr20=NOPI Ricer hate".
If I were doing that much work, I'd go SBC - like a lot of others.

because there's no performance benefit.

yeah fuck that I wouldn't put an LS1 in there either. I'd put in a LS7 and be done with it HEH. For what you get, it effectively weighs nothing and 400hp out of the box does a body good! LS1 has to be the best swap avalible as the LS1 is one of the most heavily support motors in existence, hell the 350 has been around a lot longer then any of these other motors people swap...
