hi guys,

Im at that time now in my build where the head work is going to start!

To give you guys some info before i start asking questions -

Build is going to be a track / weekend car

turbo choice was 2860-5's which i know are not the best choice for track because ive read up but i really also want some neat power figure too

so at the end of the day i need the quickest spool up i can and im sure the selection of cams will aid it...

ok i was stuck with alot of gashed to the crap lifters and rusty worn cams in the head so i ventured to nissan and got a quote for lifters at $98 bux each i told them they can keep them lol!

so im forced into buying tomei solid lifters which require small base circle cams.... so the cycle continues .... now i need cams to suit these buckets right?

minimum of 10.25mm lift tomei cams are required for these lifters so i was going to go with the 260deg 10.25mm or the 270deg 10.25mm tomei pro cams now can some 1 send me in the right direction for info on what combo i need? i hear that head modification is needed if i go to big a cam...

im kind of stuck because i dont know which size cam will give what result... like i said earlier i got -5's is any cam adjustable to give better spool ? and i dont wana hear it about the turbo choice lol strictly cam talk / advice only please..

yeh issue is i really dont wana spend 2300 bux on just nissan lifters i need to use the small base circle camshafts which start at 10.25mm lift... these suit the tomei solid lifters :( can u elaborate?

Have you looked at the Mines Cams? 252 @ 10.05 mm.

I currently have 270's @ 10.25 on a 2.8 (on -5's), the intake cam is advanced 12 degrees and the power curve still isnt dropping off at 9000 RPM.

The mines cams do come with buckets aswell. You may cough at the price (which is why alot of people don't run them), but when adding up the cams + buckets, they're not that much more exxy.

Have a look at Nismoid's car. 365RWKW on stock cams.

Ash lol fuuuuu i stand corrected crank and valves are still standard cant use stock cams the buckets and cams are f*ked ???!

Look i just want the best Option to use since i cant use genuine bukets

If your that far advanced and the power isnt dropping off at that rpm then those cams have dropped your dynamic comp that much it probly won't really react to much cam timing movement at all. I think it would be a wise choice to go to the smaller duration 252 @10mm lift. I would think that you would gain responses without loosing too much top end.

To the original poster I would recommend the same cams if you must go with that bucket size change.

Small duration, no overlap and as much lift as you can.

I love that comment because in a variable cam engine overlap is exactly what you want at low to medium revs!

But I agree with small duration and lots of lift - as long as the valve train can handle the ramps/inertia

What? You mean huge duration isn't good for a street car? :woot:

Depends on how much power your street car is making and what the turbocharger configuration is.

rob82...why do you want overlap for at low revs with a highly restrictive exhaust side?

    • Oh, that's grim. Something bad has been happening there.
    • Put an endoscope down the hole and saw this. Not quite all around the bore but a good 60% at least. Chin to the chest and towards further disappointments I guess.
    • 2 does "sort of" applies, maybe......but looking at what parts would be needed for the swap to get engineered, registered, and insured, and basically that's everything under the car, the modifications the make it legal would be problematic and horrendously expensive, all for a street car that just cruises around and hits a few twisty roads on the weekends Also, from looking at the NSW rules and Regs, with all modifications that is required just to make the car safe and not twist itself to pieces, and then actually get registered for street use, may still be impossible nowadays As for 1, when you add in a fresh engine, fresh transmission, rear cradle and diff, tailshaft, suspension, brakes, cooling, and all the other fabrication required, your probably looking at up to $100k to do it right, all for a 20 year old MX5 that is over engineered and you would never be able to actually use the power it has on the street, much like your beastie, which I love, but you actually track that thing and can use all of its powers in anger, in a safe environment  Hell, the old Bogan Cruise Ship had more power than I could use on the street, and in hindsight, I went a bit silly on that thing, it didn't really need the 500hp it had for what I actually used the car for, it was fun, but basically unusable on the street if you value your licence  As for cams, yeah, I'll probably book it in for them to get installed and tuned soonish, like next month after MX5 Mania are back at work....... and yes, I've already sent a email to bin the turbo quote and quote instead to install cams and a new Fluidampr balancer that will suit the 2.5 better than the OEM 2.0 balancer that is swapped over for the 2.5 install, as the balancer needs to get pulled to time the cams it's a while your in there sort of thing I did think a bit about flex fuel for a laugh, but being na, and no where really around locally anymore to get E85, I've binned that idea, so no sweet sweet corn smells are set for the car I wish E85 was more of a standard fuel, it's better for the environment, better for tuning, plus that sweet sweet smell we all love As for fitting in the family, that's not needed, as everyone in the family already owns a car that can seat 5 humans comfortably enough, the MX5 is "my toy" As for buying a car that is already built, nah, I would rather pick and choose my parts, I enjoy the process, and in the big picture, the additional cost is well worth the enjoyment, and the occasional frustration, I get out of doing it, albeit with other people spinning the spanners, and me, just paying the invoice 🤣
    • Excuse me, but 2) does apply 1) Would also apply if you consider how much is spent in the alternatives. Also there's the option of 3), buy one pre-built that you can put your family in (it's me, it's my car)   That said, I went on a ~500km drive the other day. I didn't use anything more adventurous than 3rd/4th gear at about ~3000RPM and 50% throttle and I was going as fast as anyone has any sense doing on a public road, with enough grip to the point where I didn't want to go any faster. I was obviously under the limit of the current car etc etc. MX5 with 2.5 N/A to achieve the same speed would be more fun for any road scenario. Maybe consider cams. I wouldn't boost it. The use case is just not there and it won't actually make the car more enjoyable unless you really do plan on wringing gears from 1st to 3rd (at least) at 100% WOT on a public road to 150+kmh.
    • Great if: 1. You had all of the money for everything else that is required  2. Lived in a country where you could actually do this and drive it legally on the road Sadly, neither applies to me As for the turbo, I am having second thoughts, mainly for engineering/registration legality reasons and insurance  Not saying I've finished doing stupid things that I probably should do to the MX5, but boost, and V8 engine swaps isn't on the cards Strange, but true
