Engine swap - H22a
 

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

:ugh:

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

It is a rather silly idea, in this man's opinion, to swap in another 4-cylinder engine, when the one that comes with the car is fully capable of doubling it's stock horsepower and destroying the tranny and diff., on stock internals.

it's his money/time, let him do what he wants.

it's stuff like this that expands the possibilities of the platform.

if he has the knowledge and skills to do it, it's pretty clear from the posts that he probably doesn't.

Ditto. I'm no muscle car guy but making 400hp on pump gas and just as much torque sounds intoxicating to me. Goodluck with your build, hopefully when all is said and done it still runs.

if you really want to dump the BP/B6 for another 4cyc there is an sr20 or a s2000 motor. Both swaps have been done before on a miata. They take a crap load of work but at least you can get some info for that on the net.

if you wanna stay with a 4 banger go with an sr20det which has been done a couple of times or something i havent seen done an f20 c from an s2000 if youre a honda fan .the s2k stock runs 13.8 gets great gas mileage and the s is about 400 pounds heavier then a miata

sr20 in miata sites

Ok thank's now I know that youd don't like the idea of puting the srt-4 engine in the miata. I've only asked about it because it isn't a very expensive engine. I've seen the sr20det swap before and it looks nice. Does anybody know how much heavier this is from stock?


EDIT:it is 2300lbs. sorry. didn't read carefully.


Thank's

I never said I didn't like the SRT-4 engine, I just think it's a waste. For my time and money, I'd be looking at a more interesting swap, like a GM V6, V8 or a Ford V8, or the KLDE Ford/Mazda V6.

theres an s2k swaped one on m.net some where, the guys said it wasent any faster then his 1.6 on boost ,the only upside was that it doesent get hot like a turbo car during autocross, i would just keep the 1.8 you have, quick question have you ever riden in a 300+hp miata? if you do you might not still think you need 400hp, just my 2cents good luck on the build one way or the other

KLZE would be even better. :bigtu: FANTASTIC motors.

Yes, but isn't the KL-DE lower compression, working pretty well out-of-the-box with boost? Then again, if I had the time and money to do an engine swap, either engine I put in would get forged internals, so I guess that's a moot point :)

Wow, nearly 350whp, not to mention extremely cool that a woman owns the car. My favorite line from her cardomain page is "Im asked about my rack all the time."

Yeah, the KLDE (also called the KL03 in the mx6 world) is lower compression. if you want to build a beast, get yourself a KLDE bottom end, go forged, get yourself some KLZE heads and a KLZE intake manifold (much better flow over the KLDE's). swap over the valve spring retainers from the KLDE heads (the KLZE's had a design flaw that caused them to crack) and you'd have yourself a monster of an engine that would love FI.

There's a guy on mx6.com (Fastest95PGT) that has a stock ZE that makes 317whp/287wtq @ 8.5psi. The car is megasquirted, but other than that, the engine is relatively unmolested. The setup i described above is capable of much more.

wow thats really impressive for a ze. i <3 mine in my MX-3, it's a great motor.

I have hurd of this car and I would like to call bullshit. Another guy in KY happend to run 11 flat (had a built up motor +t2 tranny and rear +slicks.) with video proof and her 1/4 times magicly changed from like high 11's to 10.9. All on stock drivetrain and motor. Hrmm just enough to beat him :gay:
I could be wrong and she is telling the truth...

If you really want to swap a motor in. I would do the v8 swap.

Exactly - Its just a HP numbers game to tout to others. My stock 1.6 at 6 psi can keep up with a hell of a lot of others on the freeways and most of the time not let them get by (when I'm in a mood :) )

i don't really care about 11s or 10.9s.. i mean.. she's a pretty effin incredible chic AFAIC. raced mtn bikes (or is that bullshit?), her husband/boyfriend/fiance/i-don't-know-whatever and she also owned a heavily modded FD together (or is this bullshit as well?? :confused: ) and now they own a pair of elises (i'm pretty sure this ain't no bullshit), actively winning in local SCCA SS class, yada yada, ad nauseam.

look at the
mx2000 its awesome

does anyone have more info on miatas with f20s in them

Hello

Is it hard to fabricate the mounting brackets on your own??


If you put a sr20det do you have to put in a transmission and diff that is with the sr20det?

Which transmision is easier to put in:
a)TII
b)sr20det??


Thanks

you put the sr tranny in leave the miata diff ,but you have to get a custom driveshaft

another problem with the sr20 is that it fits horizontally, but vertically the oil pan is too low. you need a custom oil pan or another solution...

How much would it cost to fabricate the oil pan by somebody?

Thanks

Well, if you're putting in an SR20DET, then it'd be easier to use the SR20's tranny along with a custom driveshaft than having to make a custom bell-housing adapter plate and a custom driveshaft to get the Turbo II tranny in there.

No clue. Find a race/fabrication shop who's willing to undertake it. My guess would be in the ~$500-750 range. I'm sure it'd be less expensive if you were able to have them just alter and modify the existing pan, but I have no idea if that's feasible or what.

Thank's for the answer

Thank's for the answer

well for the muscle car guy who posted on here i would just like to say, the reason why people lke the imports is becsaue there an actual challenge, you can start out with a 3000 dollar car and put 10k into it over time and then get the satisfaction to smoke some guys v8 car that he bought for 40k or more. Thats my opinion any other thoughts on that.

Yes. That's not my reason for liking imports.

dharrk- find an FE3 from a Ford Telstar or 626. That'll give you 2.0l that will bolt up to the miata drive line with a Mazda B2000 bellhousing mated to the Miata tranny. You just need to modify the oil pickup, sump, intake manifold and make some motor mount adapter plates. There's probably a thousand other little things- but they are little. - rob

H22a? more trouble than its worth. the stratus motor im not sure about but if you want my opinion just keep the stock motor. :)

When did the Gt35R become the right turbo to use to make 400 whp? Someone has been hanging out over on the Honda forums a little too much.
A GT3071R with a .63 turbine housing will do 400+ whp while spooling early enough to have fun anytime. Something tells me though that if you took a ride in a mid 200s whp Miata you would be pretty satisfied.

jesus fuck why swap a 4 for a 4, 302 or LSX or go home :rofl:

mmmm or a rotary...those are cool.

friends don't let friends go rotarded.

Seriously....worst idea ever.
