SR20 miata thoughts

Forum_724 · 02-22-2009, 09:11 PM

Im in a problem and I want your thoughts. I am a nissan fan and love my miata enough not to get a 240. I could get a motor for 2k but im not sure wheather its worth getting into considering there are not many out there. i want a turbo but want something different from a turbo 1.6 or 1.8. And dont want to keep replacing a rotary.

jdm slick · 02-22-2009, 09:24 PM

soo...do the swap then.

Can we keep making this topic?

You want to replace a more expensive engine to make the same power as a turbo BP.

this.

$2k will get you a long way with a BP, and you won't have to bother with all the pesky shit of swapping a complete drivetrain from another car. trust me, you don't want something frankenstein'd and expect it to make reliable power. plus SR20's are money pits.

don't confuse "being different" with just being more difficult and expensive. there's nothing drab and ordinary about a built and boosted 1.6 or 1.8.

ultimateforce · 02-22-2009, 09:53 PM

No man, we got another I AM GOING TO DO THINGS DIFFERENT. Let him just jump into shit cause he thinks we are all a bunch of dummies who never did it right the first time.

Turbo your B6 and enjoy driving it instead of wondering how much longer it's going to take to make the car run and drive properly.

driftin01 · 02-23-2009, 12:28 AM

3200 for the swap and the mounts, then you would have to get a driveshaft and all the misc, shit ...the sr has more potential then the b6, and if you wanted to make over 300 hp you wouldn't have to worry about the tranny taking a shit on you also it wouldn't take much to get the sr motor to that power level....so it just depends if you want a little bit of power or some serious power and potential

Haigog · 02-23-2009, 12:38 AM

SR in a miata is a pretty wack swap.
You could do LSx for probably the same cost just cause parts are more widely available for the swap and you'd have plenty more potential...

Honestly if you were planning on doing all the fab work anyway, Haig has the right idea. The time and money spent on the configuration to put it all together would yield you over 300hp in N/A form and rev to 6500 all day long. Now if you can keep traction is another story

Yes, I like to do shit differently. I posted to get opinions from people, not bullshit form guys like ultimateforce and toast boy up here

Nev · 02-24-2009, 05:24 PM

if you spend 2k on the motor, you're going to spend another 2k swapping it, at LEAST. the oil pan being too big for the miata is an issue. a replacment pan is available through some australian sr20 swap kit site, at the tune of TWO GRAND. they make weld-in mounts for the sr20 too, at the tune of another grand.

This swap is really tough and pointless. if you're going to do something that requires the deletion of your PPF, go v8.

for the trouble of this swap and namely welding in a transmission brace, you could just adapt an rx7 transmission to bolt up to a BP. clutch, mount, driveshaft and done this has been done for around 1k before, and solves the transmission horsepower problem. then you still have a boosted four banger thats tough to kill and will make decent numbers. if you put the sr20 money into your miata block and add a good amount of boost, you'll probably get more power with many less headaches.

Agent935 · 02-24-2009, 05:50 PM

THere was a guy in japan over on .net working on this swap too who was already making some serious power on a b6.

As far as the swap goes: Go ahead and do it! Just don't expect it to be the cheap option.

Myrmidon · 03-16-2009, 11:21 PM

I know I'm new and all, but I've been in the sr20 'game' for a year or two now, and I have to say that the transmissions on these things are absolute crap. Also, unless it is tuned to perfection, be prepared to crap a rod or two when pushing the boost. And be ready to shell out the $500 for the GReddy oil pan.

Not to discourage you though, you'll get plenty of high-revving fun if you do it.

baloyr · 03-17-2009, 01:13 AM

people are just advising you....theyre trying to keep you from doing something really pointless. its not like theyre not making sense right???... sr20..more power?maybe .. MORE MONEY for sure...less reliable... other hand......what they said... but again thats just our two cents...i mean you did post this thread.

RoadsterGarage · 03-17-2009, 07:19 AM

there is a bloke down here in melbourne australia that has an SR miata.

i dont really see the point myself as the BP is basically the same shit as the SR.

if i were bothered to do an engine swap, it would be for a rotary.

DRFTMX5 · 03-17-2009, 10:05 AM

I think a SR would be a great swap. Lots of products out there for the motor and the tranny's are a lot stronger than ours. Plus they are everywhere now these days. If something happens to my motor I will do this swap probably.

ultimateforce · 03-17-2009, 10:13 AM

Eh, I've seen SR20s rip trannies at stock boost and if you blow a SR block you are SOL in finding a block as fast as a B6 or BP.

A toyota fanboy needs to swap in a 3S-GTE or 4A-GE

But I call dibs on a 1JZ swap when I have a spare $5000.

I think the 7M swap might be a little better... aren't they physically smaller? I know the 1JZ/2JZ are huge from what I've seen.

Personally I'd be really down with a VG30ET swap, all the turbo of a VG, none of the headache of a VG30DETT. :]

The 7M weights a f**king shit ton. but IIRC the JZ block aren't that much bigger then the 7M blocks. I do want to say the JZ blocks weight in less.

I will admit a 7M would be a mean torque machine but man the weight balance would be so f**ked

Both the 7M and JZ motors are boat anchors. I couldn't find a figure for a 1jz, but the 7mgte weighs ~460lbs. The 1JZ is probably lighter but not by a huge margin.

I wanted to say it was high 3 low 4s.

Hank Chinaski · 03-20-2009, 08:04 PM

Personally, the only 4-cylinder I'd swap into a Miata would be an F20C. I don't see the point of the SR20 swap when you can easily get 2.0 litres out of a BP and not have to deal with the headaches of custom wiring and fabbing custom mounts. It's not like the SR20 cylinder head has a significant VE advantage or anything, and the weaknesses of the stock setup could be addressed for less than the cost of a custom swap.

mrryanbaker · 03-22-2009, 07:50 PM

I think we scared him off, his car is for sale now. Guess it's back to 240s.

Shawn808 · 03-22-2009, 08:28 PM

Having driven both I think the 240 and miata are totally different animals. The 240 is a torque monster compared to the miata and the long wheel base makes the tail end happy. (which is good for drifting obviously) I think maybe he should go back to the 240 if he wants that type of car.

The F20 as a solution is no different than the SR20; it makes no sense unless you have a specialized purpose. It sure as hell isn't smarter or cheaper than doing a turbo BP, but is that really the point?

I've got no problem of hacking on someone that hasn't done any research and asks a lame question, but who really cares what engine someone puts into a Miata?

I don't care what engine anyone puts in any car, so long as it isn't mine.

But the reason I'd take the F20C swap myself (were I inclined to swap engines in the first place) is that I prefer normally aspirated motors, and in that arena the F20C has a huge advantage over the Mazda mill.

I'd rather ride a bicycle with flat tires everywhere than have to drive another turbocharged car, so putting a snail on the B6 is out for me.
