having run this type of piston in turbocharged cars at high boost and detonation , i can say they seem to be a very strong design .

regards robert

yes thats why i put in the ad youll need actuators and one more bracket rich :wink: the wastgate actuators wil be for a sierra cosworth type t3, as you say theres lots of choice and pretty colours , its best to get one a bit lower than the boost you want ,say 7 or 10 psi ,then bleed off the boost to...

the swing thing is the wastegate ,you need to get a couple of actuators for them ,yes two intercoolers would work ,try to find something off a 300 bhp car in the breakers?and use 2. yes they are watercooled ,its worth using this to help the turbo stay cooler . youd take the compressed air from the o...

thanks for the replies all, so using the stroker crank which is an eagle forged item is ok, the dart heads are ok, but if needed i could use the standard stuff, but use forged pistons, as for intercoolers ,not ,so what size roughly would be needed, and i might have the name wrong but what about a p...

http://www.dartheads.com/products/cylinder-heads/ford-heads/ford-pro1-heads.html 62cc for the pro ones rich ? have yours been opened out a bit ? a good path to follow on cam timing ,since theres a bit of disagreement on here , is to contact comp cams or crower or crane etc ,and say to them hey ,here...

id use a stock crank , if you allready have the ally heads and theyre a street size port head use those , otherwize use the stock ones , um stock rods , forged pistons prob trw cheap ones , um soft cam in the 210 degrees at 50 thou lift range ,112 lsa.decent v springs to go with cam from same manufa...

id say theres a fair few bits you dont rreally need rich , a stock crank and engine size would be fine ,the revs dont need to be high with a turbo , the pistons want to be around 8 to 8.5 to one for 10 to 15 psi boost , the ally heads will be good if they have smallish street size ports , um ,really...

hi rich , the a/r tends to govern the max flow thruogh the turbo on the ex side , if a cossie will make 300 bhp plus on this a/r ,then it will work at a 300 bhp load of ex gs flow on any engine , so those a/r's will work on 600 bhp for 2 ,if you go to a bigger a/r you will get later spool and more t...

eliot ,these t3's are 60 trim not super 60 ,in case theres any confusion.

http://i32.photobucket.com/albums/d44/ivanhoew/t3-60.gif theres the map , you can roughly go 1 lb/min for each 10 bhp ,so its about 300 bhp at 15 psi worth of air for each turbo , ,then a bit more at higher boosts.they seem to max out at around 310 bhp on the cossies ,thats with the .48 housing . s...

yes i have found the same , i ran up to 17psi boost on the mini ,at 14.8 to 1 afr at avon ,and it lived !!!and ran a 104 mph terminal !!!!

thanks, chodjinn and hairbear .... that what i thought , i remember my forged omegas were shiny all over too . there is no part no ,is it possible to buy these pistons new ? what pistons are available for 3.9 rovers in the strong and capable of handling boost department , all iv found so far are the...

could anyone help me decide if these are cast omega or forged ,and also can one get rings for them , oh and also what would they be worth ? apparently they come from a twr race motor ,and have done about 200 miles ,bit of water marking that polishes out easily ,one oil ring rail missing ,can i get a...
