For a 4 cylinder sedan it's about average more on the heavy side actually
KLZE Or Forged FSDE?
- Thread starter Cmezz331
- Start date
Why is it so hard to part with cars? It's obviously the better financial decision to simply buy something better, yet I keep trying to improve the MSP.
There are plenty of decent cars that would probably cost less than a ZE swap on top of a used MSP that already have more potent V6 engines in them.
There is also the FRS and BRZ hitting the streets soon and even brand new they won't depreciate as fast as I sink unrecoverable money into my MSP.
I try to look at is as a hobby, but then there are probably more productive and cheaper things I could be doing with my time.

390.2 lbs for the FS vs. 474.0 lbs for the KL.

Just start drag racing, wont need to worry about understeer. Weight in the front is a good thing for traction

just build the fs Im building mine right now and i know ill be happy once its done. Gt2871R 
I would love to engineer a way to keep the vibrations from the FS down without resorting to stock weak rubber mounts.
Some people have claimed smoother operation with a built engine but I am not sure how.
The real troublesome area seems to be between 750-900 rpms. I can raise my idle to 1000 rpms as I know a few people have done with solid mounts, but the car doesn't really sound pleasant at 1k either.
If I could keep it at 650, it's very smooth, but all it takes is for the fans to kick on or the A/C for the PCM to kick up the idle into the shake zone. My plan is to control my idle with my Megasquirt and see if I can't just get it to stay at 650 even with alternator load, but it doesn't really solve the problem, it just avoids it.
A lot of higher end manufacturers are resorting to 4 cylinders now due to mpg requirements. Audi has been doing it forever, and the 3 series is now coming with a turbo 4. I wonder what kind of tricks they are using to smooth out the vibrations without sacrificing performance in the "ultimate driving machine."
I know Porsche has had hydraulic engine mounts as an option in the 911 for the past couple of years. The engine mounts soften at idle or cruising, and stiffen under load and during cornering. It would be awesome to add something like that to the Protege, but talk about a massive challenge. That would make a ZE swap look like baking a cake.

Huh?
Back to the topic at hand- Currently myself and another member here have been arguing who's faster- my car or his KL-ZE swapped P5. It's not serious, but he wants me to go KL-ZE instead of building my FS. I'm totally against it. I'd much rather build my FS than swap in a KL-ZE. His swap took a while, but it's all done right. I'm getting his old FSDE and building it. Swapping to the KL-ZE is too much trouble, plus I've never been a fan of swaps anyway. I've built a D15 instead of swapping in a B18 in a Civic, but that's just me.

Bseries> any Mazda motor just do an ls vtec swap and call it a day less money and weight more power reliability and potential and way more of an after market selection. Obviously I'm gona get flamed for this but truth hurts

For twice the cost and less reliable sure
There will be no talk of Honda swaps.
Back on topic please.
Thanks for all the responses everyone! Pretty sure I'm gonna go forged, a: because I have an extra engine laying around, and b: woth being in debt for said engine and transmission( after I got the new engine, 2 weeks later the tranny went. Bummer) I can buy pieces individually in little batches rather than spending heaps at once

Mine was opposite... LSD went out and $2,000 later she's back on the road for two months and then BAMMMM, the engine blew... $4,000 more and she's back on road... but only with a donor 71K mile MSP engine from 2003.5 MSP #1,482... price may be a little off, but included shipping, installation, new timing set, new FORGE WGA, couple gaskets, ARP manifold studs, AWR mounts, etc...
I think I might try to build a forged FS engine later this year and then sell this one after swapping in the forged one... I still haven't torn down the original to see if the MSBP was salvagable or not... I will probably try to get the head worked on by either Crossover or Racing Mazda... I think Crossover might be cheaper, but Racing Mazda is closer... I'll have to balance the two... I can get the head done and bag it for the future use too...

I've done the KL swap and somewhere I have a fully sorted list of prices, but if I remember right it was around $50 in my pocket when it was all said and done - and that includes the entire turbo and intercooler setup I ran on the KL. The reason being is that at the time MSP turbo setups were bringing really good money and I was able to offset the majority of the costs with that sale and then I got good money out of my msp trans because I had just put a new welded diff in it. I'm starting over with a different msp and this time I'm going to stick with the FS. The biggest reason for this is that I need a test bed for the business. If I take that out of the equation I think the ultimate MSP would have a high revving (8500) NA KLZE in it. The KL is a sweet engine, but it got to be too much headache with the turbo and everything else in my last msp.
