Single Turbo Conversion

[1gsoarer]

Can anybody tell me what i need to convert my twin turbo 1g-gte to a single turbo GT3071R?

[hypo23]

a manifold, dump pipe, modified oil and water lines, new cooler pipes, thats about it really, you can on and on though if wanted, like computer and injecters ect ect, but not required if you dont want too, depends how much power you want, or what you want to do really

[1gsoarer]

reasonable power but keeping it stable without too much lag.

[Gttwinturbomk3]

Dont forget you prob want a decent external wastegate too. And then once you have your turbo setup, to get the best from it all and your moneys worth you really need computer bigger fuel pump and injectors and some real good tuning! So all up well over $5000.
I suggest concentrating on a good base motor for starters then concider more power after that. A good rebuild is highly benifical before doing any of the above. Unless you want to watch your 1g make over 300rwhp then bugger out because of age.?

[1gsoarer]

can u give me any advice on a new rebuild?

[hypo23]

wat do you want too know about the rebuild?

all parts for a rebuild are available

[1gsoarer]

the basics of rebuilding a 1g or any advice you can give

[DRIFTAMK3]

for starters
new gasket kit thermostats
front and rear main seal
spiggot bearing
possibly machined head dependin on condition
freshly honed cylinders
pistons rings
head stud kit
prob stick wit stock conrods they are massive to begin wit and pretty indestructable
lol
big end bearings
little end bearings
new oil pump+ water pump
new pulleys + hamonic ballancer +new belts
timing belt
linished cams
reground crank
replace original engine nuts and bolts

Off the top of my head thats all i can think off and i hope it helps... there is a lot more invovled but thats all i can think off at the moment
but well worth it man im currently considerin rebuildin mine as well let me no how you go

[DRIFTAMK3]

and welcome by the way

and as for the crank and cams if yours are still in pretty good condition they should be fine but have them inspected by whoever does the rebuild just to be safe

[1gsoarer]

cheers man and thanks for all the advice.

[1gsoarer]

and any chance you know were id be able to pick most of the stuff up from?

[DRIFTAMK3]

to be honest i couldn tell you evrything but as far as i no
repco for the timing belt ask for a gates timing belt bout $110
any goodbearing shop for your bearings and possibly seals
except big and little end bearings

although i have done the front and rear main seal + spiggot bearing ill try to find the part number for ya

whoever you get to see over the rebuild should be able to get most of the enternal work done(performance shop or a good enginering shop)
water pumps bout $190 from toyota
unsure on oil pump

or try the search feture on toymods there will most prob be previous thread wit wat your lookin for hope that helps

im putting a gt30 on mine and intend on boosting it up to about 17 psi, im not going to rebuild it though at this stage as i need to get the car back on the road asap

the motor has been sitting in the bay for about 12 months, it still cranks, but i know eventually i will need to do rear main seal as it is already leaking a bit and when i do i will replace those other things

i reckon i'll just do oil filter (i have a romote mount jigga), timing belt and other obvious bits

im not going to go stupid building a 1g from the bottom up as for the money its far cheaper to get a 1uz or 1j

please let me know if ive left anything major out

[DRIFTAMK3]

yeah that is true also i suppose it comes down to each to there own i suppose i would love to get a 1j but got to much of a soft spot for the 1g at the moment ...

dude nice turbo choice wat size rear housin on the gt 30 are you gonna run
i was lookin at one my self or a gt30-40r gt35 or gt30 wit 0.63 rear all at about 17psi

Or gt30-76r 0.82 rear at 19psi would be nice to would be happy to make around 300whp

which would be nice lol

[SillyCarS]

its the gt3076r with a 0.63 housing
