That’s an impressive result on a stock short block 2.5. I’d love to see what it could do with an upgraded pair of camshafts, I image it would really rip.
We recently fitted a set of our phase 2 cams to our mk indy 2.5 kit car. See here.....

Nice work Dan,
do you think 44 t/bs are optimum for the 2 litre?
I presume you’ve tried the 48’s and they were too big?
Up to around 230-240bhp, after that then yes 48mm
You probably dont give a shit but if you are bored like me atm then you can stream pretty much all the latest movies on instaflixxer. Been binge watching with my brother these days :)
@Alessandro Draven yup, I've been using instaflixxer for since december myself :)
@Alessandro Draven Definitely, have been using InstaFlixxer for years myself :D
Any plans to make an itb's kit for the mx5 nd1-2 ?
I think you would gain a nice flat torque curve with the vvt & bike throttlebodies will restrict your power to 200bhp also
The vct is running here, hence the nice torque (turn it off and we loose about 25lbft!). The bike bodies will be good for much more, we've had high spec zetecs do 240bhp on 44mm gsxr bodies
Nice!! How long are the intakes, with the "tall" setup?
May I ask what is low speed braking and pedal feel like at low speeds? I noticed that there was a single outlet for the brake booster
Any tests done on a stock 2.0L engine with the ITBs ?
Hi, not on an MX5 but we ran a fiesta ST150 on a very similar kit using ZX10 throttle bodies. This produced 180bhp with a free flowing exhaust manifold and system. We would expect to see very similar on the MX5 but no doubt with greater torque due to the VCT.
Has already been tested,one customer yielded 203 hp with 45 mm tb's in a standart 2.0 mx5 nc.
You should expect about 200hp on the Mx5 2.0 mzr/duratec with a free flowing exhaust manifold and 45mm tb's.
Altough the fiesta and mx5 shares same base block, its not exactly the same engine and the MZR on the mx5 produces a tad more power with similar mods.
@@Theyefull thanks a lot for the info!
@@Theyefull where could one acquire said throttle bodies for the 2.0 NC?
Could this work on a Mazda 3 mzr 2.5
Any details on the cable throttle conversion?
Cheers.

How much WHP did you gain by just adding IBT ? I am very tempted to add this to my track NC 2.5 camed.
We've not run a 2.5 without ITB on our dyno so hard to make a direct comparison. But 20whp would be a cautious estimate
@@DanstengineeringCoUk thanks , where can I check your prices and ordering methods? I tried link from your video but didn't get to your website .
What cams are you running in this?
@@danielmartin6492 Esslinger Engineering stage 2 cams . They are specialized in Ford 4cl engines and they make bunch of good stuff that we can use on NC platform.
@@driver46 yea familiar with them. Seems low numbers for itbs and cams?
Do you know if the Fusion 2.5 has the high flow RF3S4G/RF6S4E head?
The 2.5 has a different, larger port head that flows similar to the high port 2.0 head.
Interesting. Do you know if there are multiple head castings found on the 2.5? I'm trying to find out exactly which motor to look for at the junkers here in the States.
If it hasn't been said, thanks for all the secret sauce details you give in your videos and here in the comments. It's much appreciated.
this is HP on whell or on Crank ?
Our figures are at the fly
