Cheap Power?

agreed, the DFA was one of the best cheap "bang for buck" mods i did back in the day. i really should hook it back up again.

Get some sort of use from that retro printer cable in the parts box in the garage (I think the DFA uses one) :lol:

"Not adding the strut brace will save you weight and money and lets you position your intake as you like. It doesn't have strut suspension and doesn't need a strut brace."

So your saying that because the mx5 has the two 'A Arms' or whatever you call them the strut brace wouldn't be that neccessacary?

That DFA sounds like a pretty good option, I think I'll have to get one.

Thanks everyone for your input!

Err... I don't see why a strut brace would not stiffen the car, its basicly adding a "roof" to the front frame of the car isn't it? - Makes a bit of a difference as far as i can see (I have one on another car)

As far as power goes, this is what I have gone for (all prices approx) - DIY Mania Style intake ($100 ish)? - Timing ($0) - N*power Extractors ($200) - Used EA Falcon Cat - used V6 Magna Resinator ($120 for both) - 2.5" Piping and install of above parts ($400) - Dual Exit Muffler (came with car, but seems to retail for $1k! *gulp*, you could get a WAY cheaper one) - Tighe 805C Cams, Self installed ($600) needs an ECU really (which i have not installed yet), but still runs just fine with stock ecu.

That got me something that pretty much feels stock up to about 4000rpm, but after that grunts its way to the rev limiter (butt dyno guesses about 110kw) - its pretty loud and sounds nice and has a very different engine character to it than a stocker.

Dunno if you would actually want to run the 805 cams with a stock ecu, though i think they have a slightly milder one designed for stock ECU - im only running stock ecu as i cant be bothered getting my ecu tuned and installed, when its going to be turbo in a while anyway so will need to be tuned for that.

wow you run the stock ECU with the 805's :shock:

have you had it Dynoed? or is that just an estimate?

as far as the strud brace goes.....I installed the loer brace first.....The the upper. It made bugger all difference

Yup Stock Ecu for now *shrug*

I plan to get the ecu installed and tuned when i have the injectors and fuel pump for turbo, other wise i will need to get it tuned like 3 times cause the injectors will throw the tune out!

It runs fine to be honest - it idles a bit fruity, but thats ok, from time to time when you back off and let it settle to idle it will stall, but not often. also takes a tad more cranking to get it running.

Seems to perform very strongly, though may have a little flat spot in the 3500rpm sort of spot, though i think thats more it coming on cam, I imagine there would be a bit of power lurking in a tune and some cam gears still.

do you have an enlarged cross pipe from mania as well?

daffyflyer · Postby **daffyflyer** » Mon Aug 31, 2009 6:37 pm

No, don't have the cross pipe - and all that will be replaced by intercooler piping as soon as im rich enough!

And no, have not dynoed it, but at the top end it pulls away from my other car, which weighs almost exactly the same and has 105-110kw, so at a guess it has a little more than that. (yeah, there are a lot of factors at work, but it feels quicker - but more peaky - than my other car)

Oh, and since the cams the revlimiter seems to be really easy to get to, suddenly gets cut off by the limiter when its making its best powah!

StanTheMan · Postby **StanTheMan** » Mon Aug 31, 2009 7:55 pm

is it coughing & spluttering when you put the foot down at 3500?

you'll probably laugh.....I'd put my bets on the exhaust.....its prolly confusing the heck out of the computer. Not giving it enough fuel at that rev range.

anyway you're going to change that anyway....so no point chasing it.

daffyflyer · Postby **daffyflyer** » Tue Sep 01, 2009 11:13 am

Nah, no cough or splutter, just a bit of a dip in the power just before it comes on cam, its fine really.

Im surprised how well they work without the ECU..

thread revival

i have done some searching up on this forum but have found close to nothing about the old SP Motorsport ECU's.. I'm sure they were piggybacks. mania said their production line ceased a couple of years ago. the only person who had this ecu, AFAIK was roddclarke. it gave him about 10kw!

did anyone know where these ecu's were made? i'm keen on locating one...

I have Rodd Clarks...and I had it upgraded, changed from an AFM to a MAP sensor and retuned. I'm actaully a bit frustrated with it because it won't allow me to change the rev limit on the car. It's a piggy-back unit that plugs striaght into the standard loom. It's got a trackday tune right now which is a little rich to keep it safe from detonation but it made more torque than an NC at the last mania dyno day....

if you're looking at offloading it, i'm your man.

Well if your not in a rush to have it...it becomes redundant to me if and when I get an NB8A head to put a CAM in.... I am not touching the SVT head on my car now... there's no cam that works for it. Plus the car is already making power past 7200rpm according to the last dyno graph with the standard cam :roll:

How soon depends on how much I pay for my next car. I'm getting a tow car incase I ever brake the mx5 and need to trailor it home. After that I'll be focusing effort on getting a 2F motor together which will need another ECU.
