That's great mate, but we're talking suck through.

Z24 cranks stroke them out to 2.4L and they go like hell. But it requires a fair bit of work to get a Z crank to fit an L series.

sorry dad . . . just pointing out that carbs and turbos have been used together succesfully for many years to the point where sealed carbs can be ordered off the shelf (mainly for V8s tho)

The world needs more angry Ford 2.0 pinto's and L20s etc imo

and im a Big engine nutter

my dads always going on about the 2L pinto engines reckons theyr the titty balls haha

are they hard to find?

Not all that common in Aus, more of a UK and USA thing, but im sure they wouldnt be hard to get.

Interestingly though, the YB Cosworth Engine that powered the Sierra/Escort Cosworths was a basically a Pinto Block with the Cosworth twin cam Head fitted.

Huge range of performance parts available in the UK

Im gonna have to stay out of this thread now because im wanting a mk2 Cortina to drop a Pinto into.

Edit

Aussie 4cyl Cortinas had the Pinto Engine so they are out there

If you ever come across a genuine Lotus head at a garage sale, buy it.

A Ford Lotus head in decent nick will fetch upwards of $20k.

On that note, if you ever spot an LZ head, steal it. You could retire on what those things are worth.

Or for that matter a genuine FIA Big Port L series head, bare, will get you nearly $20k.

Make sure you hear it at 1 minute in. Pure magic.

And if you want to hear what nearly 10,000rpm out of a Datsun motor sounds like:

problem with those things is that only the right person will pay that. the rest of the world will just see a ratt old cortina/datto motor.

sweet sounds, i'd have a Lotus cortina, sweet car.

There's plenty of Datsun/Pommy Ford enthusiasts and the internet makes it simple to get in touch with people who will pay those prices.

An FIA head was sold via Ozdat a year or so ago for big, BIG bucks. A post went up and there was genuine interest from a number of parties and it sold within a couple of weeks.

that video was obviously the aftermarket OS Giken Twin Cam head for the L series motor, not an LZ or FIA head.

How do you suppose that? Was it the title - "OS Ginken" or the start where it says "OS Ginken"?

blow through > draw through.

if you want to run any meaningful boost, this would necessitate the need for some form of charge cooling, do this with your carb now being METERS aware from the motor, you'll have throttle response you can measure with a calender (know somebody that went through this 20+ years ago with an XE falcon).

and its not just a matter of 'sealing' the carb, it needs to be boost referenced on the feed side, as to compensate for the boost moving through the venturi.

Clearly you've never owned a draw through turbo car.

no i've been told how bad it was to consider attemtping it. had an L20B datto that would have been a prime candidate too...

so why does nearly every turbo V8 thats out there use blow through instead of draw through? we're talking serious cars, making 4 figure hp, and single digit E.T's

mainly because you can get big 4 barrel carbs designed out of the box for big blow through superchargers/turbos

edit - even those turbos have mega issues, they have to have huge main jets to flow enough fuel at full throttle that they run massivly rich at part throttle (even when setup properly) and while waiting for boost.

youtube some videos on them and listen for the big miss as they go WOT and watch the huge black cloud out the back of the car,

they really are only dyno queens or quater horses that are either at idle or WOT

    • Any difference in induction noise?
    • If I got a dollar for every flipped commuter missile I've driven past I'd have two dollars   Some people get into wild adventures on the road and I doubt it's gender or ethnicity specific. I'm just glad I don't usually drive during peak times.
    • Just got the car back and gave it a good run back home Power wise, whilst it only made a extra 5 killerwasps up top at 7200 rpm, it made more power everywhere from 2500 rpm and kept pulling much harder all the way, to the point of me relearning when to shift so I don't hit the 7200 limiter, with the old intake it seemed to take alot more time to rev out, and, throttle response is also much improved  As I didn't want to remove the bumper every time I serviced the air filter (basically every aftermarket and fabricated CAI has the filter behind the bumper) it currently has a hektic exposed pod in the engine bay sucking in hot air, this will be rectified shortly after some some of my CAD (cardboard assisted design) for a alloy heat shield feed by the OEM intake tube behind the bumper, this will cop some wrinkle black paint, as well as the intake pipe for that totally OEM look... The only fly in the ointment was that the OEM "strut" brace doesn't fit over the rear runner of the new intake with the 2.5 engine is in the engine bay, as the 2.5 raises the engine up by 20mm, it's not a war stopper, and I didn't notice any difference without it in some twisties, but....... MX5 Mania is bringing in some GWR "fancy pants" braces that apparently do fit, if it bolts up I'll grab it, it is also stiffer than the OEM one, which is a bonus All in all I'm happy with the outcome      Fancy pants "strut" brace that gives the required clearance      This is where the clearance issue was, the GWR extends out past this
    • Well, I'm back from the dyno today. Some things do partially make sense. The pod filter/airbox delete picked up between 6-10rwkw on 98 - because heat soak does kind of affect things and there was playing with tune/timing/AFR. Oddly enough, the car was running much leaner than before. So lean it was audibly pinging on the dyno which I got video of:   70de0dd5-2099-4a71-8b10-6fc833fb9d59.mp4   We're talking going from ~12.7 in the past to the first run being at like ~14.0. It is now tuned to ~12.5 on the Dyno, which correlates to about ~12.1 on my wideband in the car. These matched last time, which is very odd. The dyno plots only show the dyno's reported AFR - should be last time, yet now it no longer agrees and was way leaner. Nobody has an explanation for how a pod can make the car run notably leaner, yet not really give any more power when you add fuel in. A few different types of intake design were tested:   94c22c34-7991-4902-af85-314b5f5bf352.mp4   There was no difference other than IAT with the pod sticking out of the bay. The pod sticking out of the bay (but connected) is actually still warmer than what I usually see on the road. Removing the pod entirely lost about ~2kw. But to be fair, all of the runs could be argued to vary by that amount when temperatures climb etc etc. It's safe to say that the filter isn't causing any restrictions of any note that can be reasonably altered in any way. This is in line with what I'd expect given the Engine Masters testing. 323KW on 98 and ~335KW on E85 is actually a pretty solid result, up about ~45kw from 99% of LS1 cammed combos, with generally much larger cams/exhaust etc as well. It is after all up 42KW (98) and 54KW (E85) from before. +10KW from a pod and removing the box is cheap as chips compared to what the head work cost per kw No, I did not get to drop the exhaust and test. When it comes to exhaust... it all just seems to change frequencies and cost or gain 2hp here or there. I don't realistically think I'll drop this to test it - because there's not much else I can really do about it/route it any other way/make it bigger/just bought mufflers. Engine masters beat the hell out of headers with a hammer to deliberately kink them and didn't lose power at all, I sincerely doubt that going larger primaries would help. If it were even possible for clearance/conversion reasons... which it's not... I may throw the E85 in there at some point and do a drag run to see what MPH it traps for science. It isn't lost on me that ~320kw Skylines do trap about the same MPH that ~370kw F-Body/Corvettes do in the USA for the same  or similar weight. (122-125mph). Of course, if I go there and trap 104mph or something then I'll just 'accidentally' have an accident on the way home from the drag strip and buy a M4.
