Carburetor Running Turbo Engine?!

[StevenCJR31]

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)

I was actually thinking of going blow through, decided against, rather buy a new engine.

hahah you said blow!

anyone want a z24 bottom end? I've got one freeing up in the next few weeks.

No but ill take a blow

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?

[zebra]

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:

You're talking a Lotus Cortina head yeah?

Not many of those in Peoples garages anymore lol

If if was going to spend that much on a 4 pot it would be a Cosworth BDG 2L

[boiracer]

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.

This is the second video. I must stuffed the link.

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

[xALmoN]

its still stuffed mang,

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.

[Silvia GTR]

One day I'll do up an old z like this

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

[zebra]

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
