Bill, what DV setup are you running?
Hooch, i have a green filter coming from Bill, should have been here by now though i think?

Last night and on way home from work i have been giving it a little more stick in 2nd gear, one word MENTAL.... bone dry roads and masses of trye squeeling, i haven't revved it past 6K either.
Bill what do you think a safe rev limit is for my engine?
cant load it up in 3rd gear as boost is going to high 1.9 - 2.0 BAR which is a little high it think until its mapped, but by god is it fast.
Oh and i was wrong about spool up, its more like 0.70 bar at 3000 - 3200 rpm.
Phil my memory is real bad, what you getting done fella?

Wow, sounds awesome matt. Bet you cant wait for it to be mapped properly.
My cars having scat rods and JE pistons with all new bits bottom end and head. Havent done the valves as i got a spare large port head to work on for that.

yeah your old ECU mate, should be going for mapping in the next 3 weeks i hope, once gearbox is done.
i have 007p at mo. tim runs x2 similar dv's on his tho on his gt30r.
i have a phat as fcuk forge dv to install when i get a mo to see how that works..
your filter should have been with you by now.. has it turned up?
i revved to 7800rpp for a long time.
my fp green when i run it spooled 1bar at 3500rpm as a ref.
Bill, filter still not here mate.
I will see how it goes on 007P for now. Mine is making 1 BAR @ 3500rpm too.

Mat, just to check what manifolds didnt fit..
ATP mani, didnt fit.
Backdraft didnt fit
Impossible, was **** so you didnt bother?
JBS equal length fitted.
So the size difference between hoochs gt28rs and yours must be pretty big as he runs the ATP one doesnt he?

I'm sure hooch will say which one he has and which one is needed to get the 2871 to fit as i'm leaning toward that now.
Strange how matts didnt fit tho and hoochs did.

is the 2860 the same as the 28rs?
I think hooch's is a jbs one

Manifolds that defo don't fit ibiza are:
ATP Golf mani.
Impossible performace might, but it was that **** i didn't even try.
Backdraft doesn't which is a shame as it is a nice bit of kit.
JBS equal length does fit.
The GT2860 is a 28RS as far as iam aware.
mine is the GT2871R which is physically the same size as 28RS but larger internals

anythink would fit just depends if you mind taking a grider and welder to the bulkhead...personally i woulda got the grinder with mani number 1 lol
but thats me
but thats me
LOL.
Thats one thing i didn't wanna do.
Plus i was always planning on getting equal length mani, just not yet. But all worked out cool.
