new swap kit on the market
 

http://www.speedworks.com.au/mx5.htm

now there is a company making a swap kit for the sr20. Seem like it would be a good swap.

The only issues I ever seen with SRs are powersteering leaking, running a PS-less miata is not a problem compared to a PS-less 240

I dunno if I want any engine that can only have about 1qt of oil in it.

It looks as if the oil pan still holds normal amounts of oil.
unless I missed something

Hm......That would be Really interesting. I think even an all stock Sr in a miata would be pretty quick. And parts wouldnt be too bad for it if you go on Nico. But, with that price tag, I would rather add another 3k for the V8 Kit Hehe.

I think the pros of this kit,

A) still uncommon
B) parts are getting cheap
C) finding the motors are getting easier and cheaper
D) cost...
in the drift scene I seen sr20 ready for swap at about 1k to 1.5k with ecu and wiring harness. That just really leaves the driveshaft. Plus a shit ton of labor, but they are selling to DIYers.

been out for awhile, possibly a good idea for a few years from now.

yeah sr20dets are getting cheaper, would be smart for those who've got the ability and want more power than the miata motor and trans can hold

I dunno, this doesn't seem like a big sump

I still say is it worth it when you can turbo and have a spare motor for the price.

I still have not seen proof of these Mega Power stock sr motors that are claimed to last for ever on the intraweb

http://www.tougefactory.com/

I work ^^^ there, and sr20 is what we do.

We have stock block sr20s making 3-350 hp all day long, and have been for 3+ years.

shows how much I know :gay:

I hate the price still...but I guess you pay for the ease of the swap.

I can't imagine paying that much for those brackets, but I suppose that's what they need to sell them for to keep the shop open. Ya know what I'm gonna say, so I won't bother. :gay:

Nothing you cant do with the factory miata motors

Yah the SR motor is great, being a Nissan owner and Part of NICO. I have had chance to own SR's Turbo KA's and now I'm on a RB.

But yah someone here hit it on the head, stock for stock, the SR is pretty much the same engine as the 1.8 liter Miata engine but with out the turbo.

The SR is a fun lil engine though and parts are dime a dozen, getting cheaper by the day :), I think a Stock SR engine would be great fun in a Miata thought.

And everything should weight just about the same since the SR is a Aluminum block.

Also don't forget to include the cost of a custom drive shaft to a cost of the SR engine and Mounting stuff.

And if you guys want a lot of good Info on the SR engine, don't hesitate to visit Nicoclub.com

sr20 is cheaper tho

and makes more tourqe

That and the stronger tranny is the biggest advantage to me

i would also think a new rear end would be in line too - something to hold the power most of us would want after that kind of swap

rear should be fine imho, so long as you have an aftermarket diff

He means the weak miat 1.6 Diff

SR motor is cheaper than a miata motor???? Please show me that, I can get miata motors for 500 that are working perfectly or less other people here can show you where they have gotten motors for less (no fan boys thinking it is one of Gods two motors the JZ and the SR to drive up prices, no MaD TyTe DrIfTa's or LifeStyle playas to drive up prices on the miata yet. Although there is Cubroadster :gay: ).

Torque can be affect by the turbo on a miata, and for the price there are better motors to swap in such as the FE3, you want torque and cheap parts ford 5.0, want more torque LSx motors.

apparently fe3s are now as cheap as Miata motors - $500

I think an SR motor is a very nice option for a miata, its not like there's a 240 craze over them for nothing. Hell SCC is looking at putting the SR in their project SE-R which is the exact motor it came with in Japan, turbo and everything.

It's a very capable motor and can hold 350 hp far more reliably than Miata, for cheaper than the Miata. Is it cheaper for a block...no, but you won't need a new one in 5 months either. The idea of a stronger tranny is nice, and i've seen a very sick SR install in a miata.

I think it's good that people are looking at other swap options, just a different flavor for those who are stuck with our weak powerplant. Personally I think the CA18 motor would be far more suited to the Miata's characteristics, rev happy and ready to go.

Other than hood clearance, why doesn't anyone put a 4G63 in a Miata? In stock form it can hold a hold a hell of a lot more power than all of the above and they've already been put in RWD applications. You could even make a simple adapter harness to run the DSM ECU.

There are tons of other engines better than the B6 and BP. For most its easier to stick with whats in the car. How many here are anywhere close to max potential out of them anyways? I don't think we even have 5 members making over 300 whp. The SR swap is bad ass. The new trans is a big plus.

is the transmission stronger? parts searches (iirc) shows similar manufacturers and some identical part numbers, at least for one of the trannies (look on m.net). I think there were debates over that or the miata 6 speed.

Is the SR better than the the miata BP I would not say that, better than the miata bp maybe (look at the Gt-R Familia). For the price though I dont know if its worth it. Especially if FE3's are in the 500's now, are you guys aware of the similarities in the dimension of some the FE3 components and the JZ motors. IIRC you can use the same pistons or rods. I forget what else my friend discovered when he did the first Miata FE3 swap that we know.


I'm sorry I just dont see the SR as being the end all motor people make it out to be. It was just a motor that help power and lasted a long time that allowed for a lot of development.

plus how many people have really spent a money trying to fine tune miata to make power and be safe with ECU's other than that that FM offers. Most of them do not post on online forums but I've see some very nice stuff come out of San Antonio Texas as well as Louisiana

and actually that link is old, has been up for a couple of years i think

I looked into doing th 4g63 RWD swap in a miata and I will one day when money is not tight. There are alot of issues with doing the swap the biggest is the tranny.

There are only two good options other then custom bell housing

1) rx-7 t2 tranny. great tranny but some issues arise. First you need a wide-block 4g63/4 which is a different casting then the 4g in 1g/2g dsm. Second you need a rare bell housing from 85-86.5 b200 with i believe 2.4l carb 4cy motor

2) dodge max tranny or d50. the tranny bolts up to a stock 4g63/64 but is not well known for hold alot of power and also is a cable clutch.

there was a person making custom bell housing to mate a w50 mark3 supra tranny to a 4g(narrow I believe) but they only made a small run of them.


Last you still need to swap or adjust parts ment for FWD setup

The 4G63 has been mated to a GM PowerGlide many times, GM manual transmissions may also be an option along that same route.

The end all 4cyl would not be Mazda or Nissan. Give me the SRT4's 2.4 or a Honda K series. I agree that the 4G63 also shits all over most other 4 cylinders as AMS, Buscher Racing and John Shepard have all shown us.

fucking holler on the k series man. I would love to have a 2.4L K series Frankenstein built for boost. Those motors are unreal. Putting a k20a head on a k24 block and putting in some cams and people are making around 250whp all motor.

Busher has mated a powerglide but never heard of GM manual tranny yet. not sure if there is a different or an issuse with with GM maual tranny.

I also forgot there is still the front oil sump oil pan to deal with.

I am sorry the SRT4 engine suck.. A local lifted the head three times even with arp. Now this was when ARP was first coming out with head studs for the SRT4.

Also as for 2.4 vs 2.4 I would rather have the 4g64 instead.... mostly cause there is still more info and support for the 4g motors...last but not least srt4 motor is is a neon motor...lol

never had much run in with the K series but I have heard alot of good things about them.

Can you find a working Miata turbo BP..no

Upgrades are also much cheaper, and the tuning knowledgebase is 10x bigger than with the BP.

For 1/2 the price it takes to make 300hp on a BP, you can have a 400hp SR and make a fair amount back selling the old turbo setup. There isn't even a need to build the bottom end for anything under 450ish.

:bigtu:

sure whatever

Maybe you fail to take into account that fact that this is not the factory motor in the miata and it takes more than just getting a front clip.

:BSmeter:

cool motors worth swapping into a miata:
4g63 (that would be so bad ass)
SBC
302
powertec v8

anything else is pretty fucking stupid.

apparently the club roadster people are invading.

I was thinking cummins turbo diesel from a dodge truck.
That way my miata can tow its own trailer to the track.

I lulled.

What kind of power are these "high power" four bangers making? I think the max power seen on a stock block, forged rods/pistons FE3 is near 1000whp - Louis Lima's ute in South Africa. The engine just doesn't get any hype in the states because it was never imported... though very popular/common in NZ and Japan.

GM ecotec--I recall 500 hp on stock stuff and up to 1500 hp with fancy moving stuff inside and bracing

I know the 4g have been making 1000hp mark. I know that AME has made 1000 from their 2.3 4g in the evo in a few different cars and i know a local here in atl is making 800ish w/o NOS in his DSM, but i know he running the 2.4 4g. I am not sure what the top is for 2.0L built interals but I know shep is running high 8s right now with his 2L.

Now I know the 4g is a rare case cause there is so much support for that damn motor it isn't funny. It doesn't help that mitsu been running the 4g in damn near half there 4cyl and the 2.4L Sohc head can be swapped for the DOHC with intake and exhaust and have a 2.4L turbo motor and can be swapped into a 2.0L turbo car for about 500 bucks(doing the work yourself).

I agree with Rob that the FE3 seem like one hella motor so unless I get funding for a 4g swap when I blow the b6 up I be looking at the FE swap instead.

I found a guy on the Vortex who is swapping a turbo Vr6 into his Miata while using an RX7 trans. One things for sure....thats gonna be the best sounding Miata ever.

I've always thought it would be cool to have a euro s52 out of an M3 in a miata. But that vr6 idea is the shit, I love how those roar.

You should sell a swap kit...mounts and shit.

I've got info and drawings on my photobucket site free for the taking.

The vr6 w/turbo seems like a good swap given it's narrow, probably no longer than the fe3 - as long as it's not too tall.
