If your going to be running that sort of boost make sure your fueling is adjusted to suit otherwise you will be replacing engine parts fairly soon.
yeah read up on this site
re jet carb
new uprated fuel pump
alloy intercooler
do i really have to get a dump valve?
What cam you got in the engine?

what would u recommend
might be a bit laggy but should be good when turbo kicks in??????????

Yeah for 1k revs then change gear. Most people who go for the larger turbo suggest the piper 285 but there are a lot of cams out there to choose from. Might be worth looking at catcams to find one suitable for you. It will help the turbo kick in earlier but still going to be laggy if you running a full T28
ever changed a cam what is it a couple of hours work?
standard cam + t28 + 20psi = :burnrubber::D
mines usually around this mark...long distance runs 18lbs...around town 20lbs.
doesnt look like much of a difference but there is when it comes to fuelling :)
:) Have you seen where the camshaft is ?
do you find its quite laggy spooky?
never looked in a gt turbo engine but do own my own garage so have changed cams before?

ive got a t28 with .42 cold side & .49 hot side with a -34 actuator.
mines pretty good. boosts from just under 3krpm and keeps going and going lol

Valve springs will aslo need changing with the 285 cam:cooter: get a vernier aswell

Is that a T25 rear housing then?
i think i will try it with the standard cam as already buying coilovers too all getting a bit expensive and see how she goes
only use her for fun so not like i have to drive it on long boring journeys to work or anything
prob change the cam when ive blown the head gasket lol
any idea what brake im likely to be at at 20 psi????????????

depending on rest of spec more than likely around 180-190bhp

:agree:
give that man a pie :cooter:
nice i was aiming for 180 bhp
set up will be
t28 turbo
standard cam
uprated fuel pump
carb re jet
induction kit
alloy inter cooler (not front mounted)
standard gearbox
standard head gasket
coilovers
some ****e dump valve lol
0-60?????????
0-60?????????
Now that depends on loads of factors, how good your tyres are, how good the road surface is, how good your gear changes, what revs does the turbo cut in. You will never know. Standard is 7.2 secs so more than likely faster than that.

Ricardo had mine dyno'd at 18psi, it made approx 180bhp/lbft I believe.
Ive modded the carb somewhat since and she feels very quick. I doubt I'm making 200 ponies but I must be close at 20psi.
Need to do a sqm run or 5...:cooter:...
lol fair point
thanks for your help again guys your the best :)

Ive done a low 5 on sticky tyres, mid to late 5's on road rubber depending on conditions.
spooky has urs got any other mods than the list ive got for mine,
not that i wanna copy or anything but sounds fooking fast!!
ive got a fmic, probably not the most efficent and a side exit exhaust.
other than that id say identical lol
ive had my car for a number of years and its been set up for the way i want it to drive.
i would suggest doing the mods in stages so you can understand whats happening more.
fuelling for 18psi is straight forward and everything youve listed is more than man enough for the job :agree:
And if youve seen me drive, you'll understand why my car is fast :p :D
sweet can wait till it arrives
not sure if this was pointed out earlier but the cam is in the bottom end.
push rod engine lol forgot haha
ever changed a cam what is it a couple of hours work?
half a days work.
half a days work.
Depends if your changing the springs though as that will take longer.
half a days work.
and i presume sparkie means if you know what your doing
i was wondering when sum 1 wud pipe up about the cam change in 3-4 hours
it took me 2 hours to change mine but thats a sohc
its all about external wastegate :P

I dont get it when people mention lag with a T28,as you say dont pull away in third. All about keeping it in the power, rev it harder:devil:
