SR20 in an MSP...

[RevLimitLaunch]

don't flame on the topic, because i could give 2 sh*ts if anyone disagrees with this and money won't be issue with it. but after doing some research on motors (4cyl 2.0's mainly) i'm greatly greatly contemplating a motor swap on the msp. in the end it basically came down to the 4g63 and sr20, same size, same intake/exhaust setup (4g63 was gonna be difficult here as inlet for throttle body is reverse, which is why i keep with the sr20). i have a very reputable shop that deals with high end cars to help out pretty much do the swap with me. ill use a fwd version (obviously lol) sr20det, stock internals are good for 450whp so they'll be left that way. ser spec v tranny will be used beefed up a bit to handle some abuse. custom axles will be made from another awesome local shop here. i figure ill need ecu and wiring harness, shift linkage, custom motor mounts. i just wanna know what else you'd think i'd need, i've been doing some research on it all to do it. i've seen 4g63 honda civics no prob and i actually have a buddy with a small block v8 in his eg hatch. i've helped swap a 4g63 in a little mirage, but that was pretty much straightforward and easy to do since it was a turbo model already...anyway help would be awesome. im shooting for 300hp easy with a garrett gt2860rs turbo which i know won't be a problem and my best friend is a mastermind behind the sr20 which is another reason for my pick. hopefully it'll be done soon, about summer time or so. gotta get prepared soon though.

well anyting is possible with $$$$ dude.. so yeah.. why not..

i'd still prefer a BP 1.8T in a msp though..

 

[RevLimitLaunch]

eh wouldn't be a bad idea, ill check into it, i just know i can get the parts i need for cheap and i have a buddy that has spare parts up the a$$ lol.

 

[Myspeed12]

how much would this be

 

[Swerny]

not flaming, but what's the point in doing this to a relatively new car?

Why not go buy something less expensive to swap this all into, like a Civic Hatch?

 

[GreySpeed]

(iagree)

 

[RevLimitLaunch]

money isn't an option, that's a big reason right now. but will it happen? big chance maybe not as a subaru lgt looks better as it will have 0 miles and a brand new spankin warranty...and awd...and power...etc. lol. but there's still always a chance and it would be roughly $6-7k with a lot of help from a local shop that i've figured in already...we'll see i guess right? basically i have to figure now, brand new, warranty, awd, fast, will be faster after the simple bolt ons already planned, but high 30k price...or very fast, very different, lots of hard work, about 7k or so plus the 14k payed for the car, and then figure in the broken parts ill get to deal with and the headache of replacements and random things that'll just altogether piss me off...

Do it. Everything's about originality and I give you tons of credit if you were to actually do this. It's all about breaking the mold. If I had the funds, you have no idea what I would come up with.

One thing sticks in my head. I once saw an old Studebaker wagon. It wasn't fully built up but was converted to rear wheel drive. But that wasn't it, oh no. It had a Ferrari 360 Modena engine in the rear turning those wheels. That's one car I believe to be truely original, and something creative like I would want to build.

So when people say your idea is "stupid" or "irrational" and ask "Why would you want to do that?," just remember that it usually takes a "stupid" or "irrational" idea to make something truely creative.

some poeple install bpt 1.8 in mx3's.. isisn't that like "not too far" of a platform as the msp? ives seen mx3 with bpts and even KLZE in P5's so somewhere in between it's doable..

 

[RevLimitLaunch]

yeah i've seen a few awesome 'better than stock' swaps on proteges and mx3's after googling. i'd like to do it since i know it isn't as hard as most people really put it out to be...not get off topic, but just look at this 2jzgte s2k swap lol http://www.hondamarketplace.com/zerothread/1940980 . enough money and time anything can be done. we'll see, obviously if it does happen it'll be heavily documented. but i don't promise it will be as i like the new car smell of the ms6, and wouldn't like the extra aroma of another new car instead....just have to see right? haha

go for it, i also thought about doing a 4g63 or sr20det swap awhile back. This would totally be the coolest thing! No more broken engines and no more weak tranny's! If mazda had just gotten it right the first time we would not even have to think about doing a swap!

 

[GMalatrasi]

I would do the MS3 drivetrain, but those parts wold be insainly hard to get.
Unless you buy an MS3 for parts lol.
Do it and be sure to post pics, vids, and dyno sheets.

To be honest with you guys, I'd find a used/abused Lexus IS300 and do an SR20 swap. It shouldn't be that hard, as the JDM version had a 4cyl already and parts could be sourced that way.

Also, I think swapping a 2JZ-GTTE (Supra TT) into an IS300 or GS300 is droolworthy and shouldn't be difficult either. They were all 3.0 inline-6 engines, and my understanding is that the motor mounts are in the same locations.

You may want to check www.my.is.net or something to that effect. IIRC the is300 motor is basically a higher comp, version of the supra motor.

 

[RevLimitLaunch]

bottom ends suck as well for holding power since they don't use the same internals altogether.

Yeah, that was my understanding too. From what I've heard, the IS300/GS300 engines with stock internals didn't hold up very well beyond 6-8psi (~260-280 whp) but I could be wrong.

Used IS with a 3SGTE would be the hotness.

 

[thaikim]

I wanna see a rotary swap in a protege, I know it would probably take more money then common sense but it would be cool to say you drive an RX-P.

 

[Alejo_NIN]

i think it is very doable
but why get the sr20 ecu and whiring harness and that bull s*** when you can go fully standalone?
i mean, after dumping 7 G's on a ca, what's one more to do standalone?

Or even a megasquirt setup.
