You'll get the gist of what where tryin to do by the pictures.
Big thanks to Speed inc for having such a nicely designed kit to take some pointers from.












All out and ready to start building headers.







skip a couple of days


headers just about done and checking fitment in the car.









Slick intercooler mounted up.

 

Nice!

 

lookin good. any plug access pictures of the headers?

 

I'll shoot some when I drop the cradle for finish welding them.

 

Looking good so far. Do have a built shortblock or using the stock for now?

 

wow..... looks very interesting..... i like that your fabbing up all of it. i cant wait to see the finished product

 

Short block will be going out after most of the fab work is done. Its getting some forged rods and pistons. Probably a bit of a dish on them as well.

 

Very nice! It looks like you got one of their "street twin kit" right in front of you when you were fabbing that. You got great skills, man! Awesome job! BTW, what are the specs on your turbos? are they PTE's?

 

They are Precision T44's, T4 Tagential with a .58A/R on the exhaust for a nice, quick spool... T04E compressor cover... 60 trim compressor wheels and 76 P trim turbine wheel.... said to be good for 600hp each...

 

Those specs on your turbos should give you an edge over most street twin turbo kits out there or kits that are yet to come.... ....that allows you to keep the a/c and without relocating your alternator . [Borat] VERRRY NIIICEE!!!

 

That's definetly pretty sweet. You've obviously got some fab skills. Is that your garage or a shop?

 

That's his shop... and MY baby!!!

i definitely can't wait until its done...

That's good to hear that you think so.... i was hoping they wouldnt be too small, but i felt that they'd defintely be able to make my power goals and more if i ever want it - goals = 700whp

 

Other specs on the build that i can think of off the top of my head:

The Engine:
- factory 5.7L LS1 (346ci) with the following changes:
- bored .010 over (347ci)
- Mahle -16cc dish forged pistons / rings
- Eagle 4340 forged H-beam rods
- stock crank
- ported&polished throttle body
- 220/224 .575"/.575" 115LSA cam
- Patriot dual springs, titanium retainers/locks
- Chromoly hardened pushrods
- Ported and Polished heads

Forced Induction:
- 3" stainless downpipes, Y-ing into a 4" custom build stainless exhaust, Y-ing back to dual 3" exits
- twin Tial 38mm wastegates
- 31x12x3" Intercooler
- 50mm Tial blow-off valve

Also putting a Firehawk hood on

 

lookin good man lookin good

 

Awesome job!

 

that looks good, what size primaries are those

 

700rwhp with a pair of t4's would be a walk in the park for you, SpeedInc's customers with an identical twinturbo kit are making well into the 800rwhp range with a conservative tune and that's from a t3/t4's. Anymore pics??!!!

 

I havent talked to him all weekend.... I'm sure he's got some though... I"ll go snap a few tomorrow and throw em up though eitiher way!

 

Ya, we got a bit more done!


passenger side charge pipe is done








Passenger side down pipe started








Charge pipe to throttle body is done as well.










And, here is what the header kinda look like. There are a couple of adjustments I have yet to do.

 

wow, that looks really good, that thing should be loads of fun when complete.
