NC MX5

[robbo_rb180]

I'd be looking at the mentioned EFR kit, room to turn it up if decide on e85 (which we know you will) and be super responsive and fun on the street.

And add whooshy noise for extra fun

C5 corvette prices are coming down locally here and a mate has a manual one and is a heap of fun on the street and track.

Gents, it will be getting the MX5 Mania kit and the 2.5 will be staying where it is

My query was about the 0.64 or the 0.86, whilst the 0.64 might spool a bit faster, would the 0.86 be better IRT EGT and mechanical sympathy, with only a small difference in spool

And as I assume I won't need alot of boost to get to 200kw, probably around 10 psi, and with max rpm at 6500, would high EGT even really be a issue with a 0.64

I'm heading into MX5 Mania at the end of Jan to discuss the install, so any info is welcome prior to that

Basically have a chat and book a time so they can throw on the turbo kit, and fit a oil cooler with a thermostat, drive in drive out of course 

In other news: just finished cleaning the car inside and out, it's now all ready to get covered in bugs and dirt driving to Goulburn tomorrow to lunch,  and go for a stroll along woolondilly River with the daughter and her boy, and of course, visit my grandcats and my new grandpuppy

assume a more linear power delivery would be better for engine and drivetrain reliability as well, IRT the torque load at lower RPM???, as well as lower EGT's???, if my understanding of that is correct, have I got that right???

You are correct, the earlier the torque, the earlier things snap

You ask for things.
You specifically state you want responsiveness.
A link was provided for a far superior, more responsive option.

Find a MX5 workshop that will install it for you. Maybe MX5 Mania will throw on the Fab9 kit. It seems they want to charge almost 14K installed for their kit, so if they charge you $6K to install the FAB9 kit then you'll be ahead?

Though really, the 2.5 with a 2860 running low boost will more or less feel as good as anything else. It's a lot of displacement and a small turbo. Think of a more modern RB26 with one stock turbo :p

TBH, truth be told I've been driving my own car, and use about 50% throttle at most for 99.9% of the time. Mr Bogan is likely similar so this is all going to be semantics for the use case he actually has. (He'll be happy with anything relative to now)

However, the EFR is hands down far superior in this use case. You really, really, really, really do notice it over the Garrett or equivalent.

I had a look at the FAB9 EFR kit, around $8500 AU before delivery, so add in shipping, installation, consumables and tuning, I believe the price difference would be negligible 

And whilst I am paying top dollar at MX5 Mania, if I have any issues with the kit they are local for support,  and from my experience, will happily go out of their way to help, hell, I've purchased parts from them and asked "how do I install or remove parts" and they have fitted a few of them for free, this means more to me than saving a few thousand dollars

And yes, 99% of the time I just plod around in the car, that may change once I start hearing turbo whooshy noises, but, as I have 3 family members is the constabulary, even when I'm up it, it is only up to the speed limit, or occasionally, but rarely, overtaking on the Hwy (I just plod in the left lane typically and enjoy the drive)

Plus the kids would never let it go if I got booked speeding, Jackie is constantly getting critiqued by the kids about her driving, which I think is hilarious, and tell them that she is "bringing shame to our family", so heaven forbid if I ever got done speeding, after all my mouthing off about her driving, I would never live it down, and it would be another thing she would bring up any chance she got

Like the time I got drunk about 15 years ago and fell out of a cab, which gets brought up at least a few times every year since it happened

Good times

I'm late to the party on this one but good to see common sense has prevailed and the turbo kit is coming.

Pre-empting heat management 

1. The Kraken manifold will be ceramic coated

2. Just purchased some peel and stick heat shielding stuff from car builders, I'll cover some of the firewall behind the dump and a little on the cam cover, this will be done prior to installation as I have ample room to get where I need to now before that realestate has more bits in the way, I'm also planning to modify the OEM heat shield to go back on, but that won't happen until after installation so I know where to hack it up, I'll also cover it with some some peel and stick to neaten it up after the hacking

3. As the dump is stainless with a flex joint coating isn't really a option, and wrapping isn't recommended for a stainless dump, so once it is installed I'll grab some shielding from car builders to cover the dump, as it has some stand off, it "shouldn't" cause any issues and it "should" just keep the radiant heat away from " melty engine bay stuff"

Not for heat management, but I've grabbed some more black crinkle coat to paint all the shiny intake pipes, I'll pick the pipe work up prior to installation and use the paint booth and big oven at work to cure them, I'll then wrap them with some bubble wrap so they stay nice during installation

Nice build thread. Ive got an nd myself, fun little weekender.

Would you ever vent this bonnet or will it be unnecessary?

From talking to the mx5 guys the NC doesn't actually need bonnet vents like the earlier NA and NB models, due to a better designed cooling system and undertray design

There's plenty of them used as street cars and weekend track toys running anywhere from around 170 to 250kw with stock non vented bonnets, I initially was going to get some bonnet vents, but, as they are not actually required, I'll put vents on hold for a while and just monitor temps, though I do need to get something to actually monitor engine oil temps though, coolant temp can be pulled from the OBD2, but the oil gauge in the car is not actual oil temp, it is only a calculation based off coolant temp and RPM ☹️

They do recommend upgrading the radiator, which I have already done with a triple pass, and the only other thing they recommend for a street car is heat management, like I talked about above to protect bits in the engine bay from radiant heat, and to either replace the nearly 20 year old plastic coolant expansion tank, which I have done, or get a aftermarket alloy jobbie for some bling

They did also say that if I wanted to track the car on occasion a oil cooler and sump baffle would be required, and as I already have had a sump baffle installed when the engine was out......... I'm going to get a oil cooler with a thermostat....... just in case I do eventually track the car, but probably not, but still maybe...🤪

full send the cnut, do this

 

fark the wrapping and/or stick on siet.

Instead of the paint on the shiney pipes, would you consider going with getting them ceramic coated, and then powder coated black?

What's the difference in wrapping it in this stuff in relation to overheating the 304L stainless dump material and having it cracking at the welds from overheating the material?

It would well on my exhaust manifold as it is some fancy pants cast material, but, I've used similar stuff before and it is problematic to get it looking neat as you need to fix it with "all" of the SS ties

The stick on stuff is just for the firewall and OEM heat sheild

I believe that, as I am only going to be running low boost and not pushing the turbo too hard (hence asking about the differences between a 0.64 and 0.82) extreme heat in the dump shouldn't really be a issue

I am happy to talk metallurgy about a 304L material and what makes it crack

More so heat management so you don't melt stuff around the turbo, especially if you decide to hit the track.

Good point, I think you can get black ceramic coating as well, so that could be two birds with one stone

Quite possible! And well worth checking out, as it will be more durable than paint

Nope, but they are definitely one of the default choices. Well established.

My manifold is ceramic coated by them, can't say my engine bay is any cooler.

If the manifold ever comes off, I'll go down the real thermo shield/wrap thing.
