Hello

I've searched on forums and did not find anything about it, so I have a question to people on miataturbo.net.

Is it possible to put in a H22a engine from a prelude into a miata and the VTEC will work? also is it possible to put a 2.4l dodge stratus engine in the miata? And if yes how difficult is it and how expensive with out the price of the engine?


Thanks everybody

 

 

the miata motor is a great platform to add a turbo or supercharger, it would be cheaper and easier

 

Yes, it is entirely possible. How much money do you have?

 

I'm doing a research if it is possible, how much money will it cost and is it very hard. i'm buying a miata in may/june '06.

I would also want to know which is cheaper and would be capable of more power:
a)1.8l miata engine forged pistons and rods (stock crankshaft)
b)2.4l straus/ srt4 (stock srt-4 internals)
c)2.2l prelude vtec(forged pistons, rods)

It will be turboed in the future.

I have money for the car at the moment and plan to put the bigger or build the 1.8l engine in the winter 06/07

Thanks

 

Stock-for-stock, the SRT's engine will be capable of the most power, probably followed by the Miata engine. If they're all built up with forged internals, the results will probably be the same.

There is no one I'm aware of that has put an SRT or H22 in a Miata, so there is no kit. That mean you'll be doing all the fabwork, plus the cost of materials. You'll also want to factor in the cost of a standalone ECU, I would think, if you're planning on pushing any of these engines.

My guess is, it'll cost $3,000-5,000+ for the fab work and materials for miscellaneous items (driveshaft, PPF custom-fitting or custom tranny mount, possible custom diff. mount, possible custom axles, bespoke exhaust, engine mounts and fuel lines, power steering lines, a/c lines, oil lines, heater/radiator lines, intake tract pipes, intercooler, turbo, etc.). Then just add the cost of the motor (no idea, but maybe $750 for a shitty H22 to $4,000 for a crate SRT motor?) and an ECU (~$1500-2500), and you're done

Oh, and you might factor in time spent. Oh, and those motor prices would not include the forged internals or the labor to build them.

Or, ya know, your Miata already comes installed with a motor capable of 300+rwhp on stock internals (with a good tune and standalone ECU and injectors). Plenty of power to move a ~2300lb. car pretty smartly.

 

Let's get to a more fundamental question here...

Dhaark, you do know the miata is RWD right?

 

And wouldnt the Honda give you alot of recerse gears?

 

Transplanting a FWD platform engine into a RWD chassis is likely going to be an exercise in extreme frustration/futility. If you must swap in a larger displacement engine go for something from a 4-cylinder pickup or other RWD vehicle (e.g. 240SX KA24(D)E).

If you really want more displacement a 2L stroker kit for the 1.8 will probably cost about the same as going into uncharted engine swap territory and result in fewer headaches.

 

Indeed it would. Keep the 1.8, stroke it to 2.0 and turbo it. that should more that satisfy you.

 

Yes I know it's a RWD car.

Probably I'll just buy an NB and then get forged internals for it and keep the 1.8l displacement + turbo.

Thanks.

 

Forged internals are not nessicary either. If you have the money and really want the power buy one of those ls1 miatas.

 

I've asked about the H22 and the SRT-4 engine because i like the 4cyl engines. i personally don't like v8 (except if they are in suv's, pickup's).

Will the stock 1.8l be good with a GT35r turbo?

 

No, the GT35R is an enormous turbo. This isn't an EVO or an SRT-4. If you want 250-300hp, a miata is fine. but if you want more, get a 240sx or something.

 

ok Al Hounos, but having a 400hp 4cyl miata would be great, maybe not reliable but fun to drive.

 

probably not even fun to drive with the lag the GT35R would have.

 

I find this funny, you are asking about a job that would take massive fab work and you dont want a v8? Are you crazy man? I would rather swap in an LS-1 before a 'puny' H22 or srt-4 motor. Do you not realise that you can easly get 400+whp out of an LS1 N/A and have Much more tourque. There are guys making 400whp and then running a 200shot on top of that. I dont get why people say, "Ya I love 4cyc I dont like 8cyc!" What the hell? They are both motors, do you think somehow an 8cyc is worse than a 4? Its annoying when people dont like "American" and "V8" for almost no reason.
V8 roar > Vtec

When I see posts asking about crazy swaps and sky high HP, I would love to see it happening but 99% of the time its just somebody dreaming.

 

Talk to any of the High HP miata guys and they will tell you after 300whp the miata just cant handle it long term. You will be destorying tranny's and rears constantly. Also the rear suspension on hard launches with slicks (Face it you will never get traction on street tires, there are guys that have had wheel hop in 3rd.) can ruin control arms and such. They actually twist! Miatas can make fun drag platforms but if you want sky high HP you might want to look at other cars for your 400+ HP lust. If you can afford a 400hp miata you can easly afford just to start with another car and then get a miata to have fun in too.

Is there anyone that has built a 400hp miata for less than 20k? I doubt it.

 

I think there was a 450hp miata for sale somewhere (it had an FE3 engine).

I am just asking if a H22a or a 2.4l stratus engine can be put into the miata and how much money would have to be put into the project.


I think after the purchase of the miata I am going to put in niew suspension, roll bar, TII trans, TII Diff. And after that build the 1.8 engine out of the miata to be reliable at 350-400hp level.

And I don't like the V8's because they are too big for a car like a Miata. - my opinion!

Thank's

 

if you're going to go with a 2.4L go with a KA24E out of a 240SX, it's at least RWD
