Turbo's

[Rowbotanator]

im curios ive herd that the turbos on gt4's and the bottom end are not so good and prone to go wrong is this true or is it purly down to how people treat there cars never owned a turbo and this is one of my concerns? cheers

the turbo's in some GT4's are ceramic, that means their lovely and light, spool up quickly but after 10 or so years of use or abuse the shaft snaps, just general wear and tear really, obviously good maintenance (spelling? lol) will prolong the life of the turbo but it will go eventually.

the bottom ends on the ST205's are what you've probably heard going, that only happens if the engines been modified on the cheap, det causes the piston rings to go.

under normal use the engines are bullet proof, even under mild tune they are strong engines, mine produced it's 252BHP with a blown head gasket!

when i get mine im looking at front mount intercooler, walbro fuel pump a good filter kit and nurspec exhaust so not goin mad ow and running at 1 bar boost apparently thats as high as i should go to allow for internals to be maintaind. i am a tech anyway so when i get mine it will be serviced every 4 month 4-5 thousand miles with a good turbo time for allowing turbo to cool. so hopefully i should be good and runnin a decent bhp

what model are you talking about? the st 185?

[dawesy]

if its a 205 then ditch the FMIC, it is not worth the cost and hassle to fit. the standard CC setup is good for 400-450bhp anyway. 1.1bar is safe on the 205 as well will get you to about 300-330bhp.

if its a 185 ATA then the fmic isnt a bad idea and unless your fitting a metal HG then i wouldnt go above 0.9bar

[damogt4]

to get the boost uped do i need to get new ecu and ebc

[led-gt4]

yea the boost controller is how you would increase the boost. ecu isnt needed unless you are planning on going to unsafe levels ie above 1.1 bar

[damogt4]

no i have three st205's one for parts the second one has a cracked piston and now as u no the turbo is ****** on the new one so im going to rebuild the one wit piston gone and want to run more power

[led-gt4]

my god u must b minted! lol well mate u are in perfect postion to make and amazin gt four then. im looking for a few parts if you breaking any of them soon. i need a power steering pump and need the shaft that goes through the bulk head and connects the steering colum to the steering rack, the eash way connection knuckle on mine is squeezing. plus any bottom arms and banana arms in good nick. just something to keep in mind. u can get quite a bit from breaking these cars. oh also need the arm rest lid thing
