lol, this thread is so damn stupid

thanks njn63, thats pretty neat, the rear drive k series is intellectually interesting because you get to pull motors and aftermarket parts from front drive market which makes it a heck of a lot cheaper.

I don't have a bp block to weigh, but a bare sr block with maincaps is 62lbs.
I hope thats light enough to offset the weight of the turbo hardware.


ok guys, i'm very close on the mount. I want to make sure i'm running the ppf at a safe distance to the gas tank. Can I get somebody to help me out and measure their gas tank to ppf gap? I am running something like 3/8" which doesn't look like an aweful lot to me.

here is current version of mount. i think with one more change its ready to run for this year.

Unless that dyno is totally unrelated to the SR you're swapping in, those numbers don't make any sense. Blah blah, different dynos, yadda yadda, I stick by my statement.

Also, coming from my brother's experience with years tracking an SR-powered 240SX, they are FAR from "reliable". Even when made reliable, its all the same ---- you'd do to a Miata motor. Might get a little more power "reliably" from one, but not a whole lot. He was making ~280whp with an S15 turbo. Really fun, but ---- broke all the time, and he was safety-wiring nuts and bolts and such. When that all finally held, he started melting pistons.

It's not JDM; therefore,

100% agree w/ you. but this makes me quite happy, as this gives me something to shoot for.

your right, the chart is an NA chart. if anybody has interest i'd be happy to discuss in my build thread.

Jason I don't know anything about that motor but would love to hear more about the weight savings etc.

jasonb

im dubious there is much weight savings at all:





With aftermarket clutch, top mount exhaust manifold, external wastegate, cast pan, oil, and alternator.

No water, starter, air filter, MAF, intercooler & piping...

349.8 LBS

Huh. I am interested, looking at fail baboon now.

post started 31/3/2012, with all that time and the money you gonna spend you could have a 350hp b4 or bp mx5 by now. i did a 1.8l conversion to mx5 and it took me 3 days at home everything is bolt in and plug and play!
its obviously youre ignoring all advise and trying to be different.
with regards to being reliable it all comes down to the tune, i was reading a thread on here of a guy running 350hp on stock motor!
after your engine swap you still have to upgrade suspension and bracing if you wanna track it = more money.
i understand youre trying to be different and good luck with that but one day you'll race a bp powered mx5 and realise how much time and money you wasted then LOL!
