No worries it's all related and makes interesting reading.

Apologies to Eddy - and a big thumbs up too! - can`t wait to see the results - should be fantastic

The standard pistons/crank are fine for 500 - just the rods are dodgy i`m told - I read that some of the Vortex guys have passed an incredible 700bhp now!!

Would think that the largeport head is advisable for big power

is anyone doing CNC porting of 1.8T heads in UK? -I know Cosworth are producing CNC jobs for Sub/EVO

EddyH · 20-05-2006, 18:44

Unfortunately I think it's a bit late to go large port now as my head has already been sent off for matching to the valves, however the inlet valves will be 1mm larger diameter than standard.

I`m sure the inlets on a ported smallport head will flow plenty enough - it would be interesting to see the flow data ported smallport/standard largeport

The theroists always worry more about flow capacity on the exhaust side - port/manifold/turbo/exhaust - any restriction there with big power outputs, and things get `difficult`

- according to the flow data there`s not much difference between the exhaust ports in the two heads

Are you smallport or largeport Steve?
Dahlback does'nt port to largeport properly as the runners are very narrow still.

*caney* · 21-05-2006, 10:11

hi bill,mine is still smallport got the mani off edd's sportec golf as he's having a custom one built by them

*ryan_s3* · 21-05-2006, 12:25

Looks good for my up-coming largeport head with those graphs.

*ryan_s3* · 21-05-2006, 14:53

No big plans steve,thought i told you at pod what i was doing.400bhp max, probably a bit less.

you've already got a bit less! 360bhp

Update:

The pistons arrived last week, the block was sent off and has been bored out to suit the new pistons.

Rods arrived this morning.

That's the plan but I think I may struggle to get it sufficiently run in to grace the strip but I'll do my best dependant on when it's finished.

Here's a photo of one of the 83mm JE pistons which I was sent today:

Hmmm isnt this the same Edd that said "I like my ko3s and wont go big turbo?" Just gone HUGE everything!
Look forward to seeing it at the show...

Yes.

Truth is though I'd tried IHI and GT28RS and they weren't for me. However I tried a car with a similar setup to what I'm going for and it just felt right, I knew straight away it was what I wanted for my car.

360bhp at 6100rpm then nosedive,
this time it will be 400bhp and held......hopefully.
I'll leave it too you guys for the big numbers!

lovely lovely

5 valve pockets

some higher lift cams?
wondering what CR from the crown of the piston.

shame you cant seem em when they're in the motor.

EddyH · 01-06-2006, 09:20

The valve pockets also have me a little puzzled as the cams and crank are staying standard.

I agree it's such a shame that the pistons won't be seen.

EDIT: The cut outs are for use with high lift cams (which I won't have), the compression ratio is 8.5:1

ibizacupra · 02-06-2006, 09:44

swap ya!
