Don't forget about the other costs involved with the cars. Call you insurance company and ask for a quote on that Lotus.

The Miata is cheaper to maintain, easier to fix, easier to get parts for...and when you know your car and are comfortable doing work yourself, you save $$$.
I am caught in a similar debate. While I love my car, it's speed, the handling, looks and everything else, sometimes I still feel like I'm driving a "boyracemobile" and should be working on something more "mature". But for now, I'm keeping the Miata, fixing/upgrading the little things and plan on holding onto it for awhile. I'd say just get the turbo kit put on, get a nice tune (go for the 260/270rwhp) and have fun with it...while working out the built engine details.

I've used a local rebuilder (there is a difference between a builder and a rebuilder) to myself and he does any machining I can't, which is minimal.

I do most things myself and have ~4k into my engine ancillaries and turbo set up and it's reliable for the street but I bought loads of things second hand and my engine is stock.

For the $$ you're talking to have a turnkey car it doesn't sound bad.

I really would think about what doppelganger is saying re insurance, image etc. I drive my car because it is what I want and not really a compromise.

If I could own a lotus as a fun summer car and keep the miata for more of a scary track day car I would in a heart beat.

My good friend used to have an elise and I absolutely loved it. I am not into buying a car and leaving it alone, but I could appreciate a well balanced extremely light weight car that I could fling around back roads from time to time.

If I had to choose solely between a high power miata vs bone stock Lotus tho... I would choose building my own Miata. Same reason why I have a 225 rwhp endless project rather than a near stock s2000 for the same money.

I also have a yellow 2002 SE. I am running a stock motor with a FM11/Hydra that I installed in 07 with a Act clutch and light flywheel, 2.5" exhaust, tein monoflexs, 55mm rad. and other odds and ends. I haven't dyno'd it, but similar setups have dyno'd around 230 whp. I haven't seen an Elise that can go by me yet on the track. You don't need to build your motor to have it fast if you want to settle for say 40 hp less. I run 11 to 12 psi. John

Sounds like the same progression I went through to end up building my LS6 '01. I've found I enjoy tinkering with my turbo cars that were already boosted cars ('05 Suby LegacyGT and now my wife's Mini S supercharged) than building a turbo car from a non-boosted car. That and emissions, and aftermarket ECUs and readily available parts.

It's the slippery slope that never seems to end. I've still got a little ways to go to have my car be a daily driver without quirks but I'm closer than I every was with my built motor/turboed car.

I do question if you could live with the Exige as a daily driver if it was your daily. Especially in NY with crappy weather and actually seasons that aren't 80 degrees and dry.

Thanks for the feedback everyone. jmann aren't you selling your car on craigslist? How do you like the monoflexes? I have a set waiting for me to return home. Right now I think I'm going to take the slow and steady approach. I'm tabling the build in favor of getting the ECU and learning to tune on the stock motor first. I would hate to mess it up and blow a rebuilt motor due to learning curve. jmann how do you like the Hydra? Right now its a toss up between the FM Hydra and Boundary Engineering's Adaptronic. Experiences on each would be appreciated.

Yes I do have the 02 SE for sale on Craigs list, thats because I bought a 99, which I have made into a full fledged track only car. I just couldn't bring myself to do to a yellow SE what I did to the 99 for the track. As for the Hydra I have the 2.5 in the 02 as it was installed in 07. It has been problem free, I haven't had a laptop hooked up to it since about 4 weeks after installing. There are a few quirks that are different then the factory ecu. It takes a smidgen longer to start then the factory ecu and when you have the ac on or on defrost which also runs the ac compressor it idles up and down a few hundred rpm, nothing that bothers me though. NOw for the 2.7 Hydra. It starts the car just like the factory ecu. As for the ac idle thing I can't say as I took the ac off of the 99, but still have the heater in it as we have alot of damp track days here in the NW in the spring and I want the defroster working. I have used the defrost and its doesn't change the idle like the 2.5 does, so I am assuming it wouldn't either with ac on. The 2.7 autotunes all the time, even without the laptop hooked up, as to where the 2.5 only saves about 12% without the laptop hooked up I believe Jeremy once told me. The maps in the 2.7 are bigger and better. Another thing is the 2.7 you don't have to upload from the ecu to the laptop when you hookup to it and download to the ecu when unhooking. The 2.7 does all that automatically, so any changes you make to any maps while hooked up to the ecu are automatically saved. The only time you have to hit save is when you are doing changes off line with the laptop. The big issue with the 2.7 has been getting it to control the alt., and that has now been fixed and works great. Both versions of Hydra controls the VVT very excellent also. As for getting used to it first, I wouldn't worry about it. There really isn't much playing around you need to do unless you are a geek and just can't kkep your hands off of fideling with it. The only changes that really need to be done is if you dyno the car and want to get every last HP out of it. You tell Jeremy what your setup is and he well install a base map in it and it WELL work with the setup you have right from the getgo and the auto tuning well do the rest. I am not a computer geek, but I do understand enough to surf around in it but have never dyno'd either car and they both go like crazy and have never hurt an engine and I drove the 99 around a doz. different track days hard in "A" group last season without an issue and have never had one with the 02 either. Good Luck

PS As for the monoflexes I like better then the earlier flexes for using on the street also, as compared to other brands I can't speak as other then Koni sport this is all I've had on a miata. I hear the Xida's are great also but cost more. I have 10 kg frt and 8's rear for springs.

I lived in Port Orchard, WA from 2007 to 2011. I think it's funny that after I left the Miata scene seemed to pick up. Does the 2.7 have map switching? I'm thinking of having different maps for fuel grade.

jmann

I don't know, I would call FM and ask Jeremy. Why were you in PO?, were you in the service, NY is quite a change.

mcs6979

Yes I'm in the Army and was stationed at Joint Base Lewis McChord. NY is quite a change, but luckily for the Miata she'll be put away for the winter months, unlike the 70 mile commute she had to endure every day. I'm glad to hear that the Hydra can be a "set it and forget it" affair. I was originally thinking MS but it seems like the MS users are constantly HAVING to tweak their ECUs. It seems that as much tinkering needed to keep the MS ECUs happy, one would just switch to carbs or IRTBs.

mcs... what are you going to use this car for? I skimmed the thread again, but I can't find what you're going to do with this thing?

mcs6979

Everything. More DD than weekender (toy) then as time goes by she'll be retired from the street, minus the occasional jaunt on the highway or the track. My oldest will be driving in 8-9 years and my youngest in 13 or so. I'm looking for a good deal on a 02SE Grey as well. At the time they start driving, I'll let the oldest choose which one she wants and will reprogram the ECU to MSM specs. At that point in my life both cars should be identically setup. One for each.
