5 GT Turbo Punto GT Manifold for C1J Conversion?

[Big Steve - Raider]

Has anyone ever tried offering up a Punto GT inlet manifold to a C1J engine for an EFI conversion rather than having to re-machine the original C1J one?

They look similar...

dam yours has injectors and rail!

Saab 'reds', which should be good for mid 200hp. There is a bolt-on fuel rail (which I can't bloody remember now which model it's from) that has a 3bar reg' already in situ on the rail, to make life a bit easier.

rack your brains then martski, im getting tempted to do a cheeky efi conversion at the same time as the engine swap lol

That looks close! You could cut and shut that on to a C1J flange too, see my Quadra thread and what i did with the Pulsar ITB's.

The Felicia fuel rail rings a bell...

forget the fabia manifold with a bit of trimming and redrilling it will go onto the head but once on the car it sits to low and requires the rerouting of the downpipe. as I first went that route when adding EFI and all was well up to trying it on the car.

Could you not hack a v shape out of it and angle it up a bit?

Got a Punto GT manifold on the way.

is there not enough space to have a custom downpipe in there? dont suppose you have a top view do you? id be confident in doing a cut and shut on a downpipe over the inlet

I'll get them uploaded later. I went with one from Michael terney in the end for mine.

nice one cheers buddy

 

[Adey]

just received my one, it is indeed very deep

here are the pics

Did it bolt straight on, or a bit of tweakage required?

 

[roy h]

it needs a bit of trimming and if I remember correctly 2 new holes drilling but as it is ally not to hard to do. you can see in the last pic where it was trimmed down

So got the Punto GT manifold in the post today and had a little play! Unfortunately not as similar in size as first thought... offered up a C Series Gasket for reference and you can see it's only the right size in one of the 4 inlets...

So I then dug out the Skoda Fabia inlet I had to just take a picture for your reference and you can see it's a good match, straight out of the box! It's just the matter of the "dangly bits" getting in the way of the exhaust (as mentioned by @roy h) that cause the problems:

The fabia manifold looks pretty poor in my opinion. You could probably chop it about a bit and knock something up out of the two. Just whack some injector bosses onto the oe manifold and a throttle body or buy a tierney one it will probably work out cheaper than the fabrication costs. Ideally if power is the goal you need a proper plenum like glens old inlet but you will need to chop the bulkhead.

 

[Adey]

i was actually thinking quite differently brigsy, the fabia inlet has a fair bit of volume and decent length on the runners?
