What would i expect from this spec 2wd ?

fresh 200 block standard comp
standard head
83lb siemens
ut t38

also all the other usual bits cooler group a pump etc

cheers paul

 

400+ a rough guess what housing on the turbo?

 

the big housing is it 63 ? on greys at the moment but prob go siemens, made 412 on the same spec with msd chip

 

Yeah i'd say 400-420 ish, i'd defo go with a live map though...

Remember, my 205block on my saff was @ 450 and it lasted fine, still around now actually, BUT if you're going form fresh then 200 block is best.

 

I would get the AB07 cam fitted that i have, made a massive difference

No valve cutouts required

Steve

 

was going for porting but dont think i can be arsed with the money, are the 83lbs much bigger than greys then ?

steve i was thinking about that cam whats the cost ? i have no cutouts so its ideal

 

Yeah, 83lbs will do 500+...72lbs will do infact for 450..

Cams are a HUGE must though as Steve says..

 

oh ok didnt realise theyd flow that much, maybe i should keep the greys and add a cam and maybe up the boost, made 412 @ 28psi but i think the msd chip will allow 32 peak

i will be going for live map but just want it back together and then safe some more pennies for that.

Hows your going now pete with all the new bits ?

 

Yeah i think from memory Greys will do 430-440.......


Yes mine's fantastic, trouble is, i'm pondering something else already...

I'll have to think long & hard cus i have money burning a hole and that's NOT good for me...

 

The head really needs some work and a cam to see good power

 

Just change the inlet to a BD14 or 15, there's no magic cam, at the end of the day lift and duration control what goes in, I use reground cams, where there is enough base circle, my BD8 is going to be ground to BD15 next year.
Greys will certainly do 450 without a problem.

I got the cam direct from Kents, best phone them for a price.

Power held on so much longer with mine, think i had a 34bhp peak gain and 44bhp gain at high revs

Steve

 

Without a problem ?
They're on the limit at 450

To the op, I would invest money in head porting and a inlet cam it makes it a far better engine allowing it to breath more up the rev range

 

I just had my injectors cleaned and they flowed 490cc/min@ 3 bar, official flow is 503.4cc/min.
490cc/min on a cossie = 490/5 = 98 X 4 = 392, making each bar worth 130, now add boost to 32 psi, oddly enough Fast Ford in September 05, page 56, rated the greys from 450-500, that was written by Alastair Maine.
