blow off valve mock up




i dont like how close the turbo is to my maf so im going to have to make a heat sheild but thats no big deal



all the 3" pipe is just mocked up. the red couplers are all rubber and are worthless. i need to order silicone replacements. thought it would be around $140 for them all but found them for abotu $70 shipped including t claps so im happy about that

zoie, id like to see about 650-700fwhp from the turbos and then im going to spray it with nitrous

i had the headers and down pipes made for me. i just didnt have the time to do it and my welder has seen its better days. i need a new one but dont want to spend the cash right now. the rest is all me. got all the cold side piping off ebay and cut it to fit. those intercooler kits come with a ton of piping. i have about 25% of the 2.5" piping left and about 50% of the 3" piping left

i know some about the vecco kit. ive heard mixed reviews for that kit.

the turbos in the vecco kit are only t3's which means they are small. mine are t3/t4 hybrids. if you want t3/t4 turbos with the vecco kit its almost $6000. you could buy a kit from b&g including the garrett turbo for $3000-$3500. i think they only make single turbo kits. also, all the parts are stainless but it doesnt say what grade of stainless.

did a little more work on the stang this evening. i test fit the radiator and it fit great. i need new mounts tho cause i lost one of them.




i totally forgot to check for radiator hose clearance when i did the discharge tube coming off the driver's side turbo. i got really lucky that the stock radiator hose fits right through the maze of pipes.


i was dissapointed that the waste gate hung so low. its way too low. first speed bump i hit and its going to rip right off. this means im going to have to cut the pipe on the ends, twist the middle upward and reweld it in place


i test fit my electric fan (which has the stock coolant overflow tank attached to it) and it didnt fit. the fan will fit just fine but the coolant over flow has to go. ill probably just buy a cheap one from summit. they are only $10-$20

i have thought about going with BG or quicktime turbos for a single kit but i keep seeing your twin set up and it just looks bad ***

Hope that single wastegate works ok for you.
keep an eye on your boost gauge for few times to make
sure its controlling turbo spool-up ok.

Looks AWESOME!!!!!, got mine getting fab'd now myself finally!
