Thank you for opening up some alternate thinking for me on one of our track builds here in Oz. 👌

Thanks for sharing, great build and driving video's. I am putting together a 99 BP4W for my 90 Miata. What size injectors are you running, harmonic balancer? and aftermarket ECU? Thanks

Thank you so much Artur ! I was looking for some ways to improve mine (I also have the 1.8 nb BritishRacingGreen). I got the SW388 15" rims from Spoon and Yoko Advan A052. But I liked the A048 more, especially on wet conditions. I broke 2 wheel studs last time on track (Geoparc St-Dié France) on the right front one. These were 22 years old btw ! Are yours stock too or have you replaced them ? I managed to get a front set from US brand ARP supposed to be tougher.
I noticed that you had to relocate the washing bottle too, as my stock one melt because of the Racing Beat manifold exhaust I put lol !
I'm not pretty sure I got it regarding the inlet manifold, because that's a long time I think about getting the CAI. Does it fit with standard nb inlet manifold ?
Great video !

Did you have to do any modifications to the Il motorsport cold air intake?
On the website it says it is not compatible with aftermarket radiators.

What an amazing driver you are, that was very very impressive 👍

paulfrench

how did you manage to get it road homologated

gptcompany

how did you make the air intake fit with the radiator? because on the website it says that the intake only goes with the oem intake.

The nd disc upgrade, so you use the front or rear nd disc and did you have to drilling or mod the disc to fit?
Thanks

Czy możesz napisać jaka chłodnice posiadasz ponieważ na stronie IL jest napisane ze dolot nie jest kompatybilny z większymi chodnicami ?

Hi Artur,
G, day from Australia. What is this comment from you about the VVT as a non interference engine being a myth???
I shunted over to CAR PASSION to learn more but could not find the video.
Could you please let me know which video?
Thanks and a great car you have built.

Is the power steering unit in Europe different than the North American one? That power steering pump (I think that's what I'm looking at) certainly doesn't look like mine. Is it a stand alone, electric pump so you don't need to have any parasitic drag on the engine?
