Twin 61mm turbos, Trick Flow heads put down 1,000rwhp
 

So I bent a few valves when my timing chain broke few weeks ago. Fluke event... Upgraded to a C5R duel timing chain and figured why not upgrade heads since its all apart. Added a set of Trick Flow 215cc heads CNC ported and swapped out my cam to a Brian Tooley Racing turbo cam and on 20lbs it put down 1000rwhp but the turbos were out of air and it was getting lean. So we backed it down to 18lbs and it made 970rwhp safely. Here my dyno graph. Enjoy! The car is at the body shop now having the rear Twin Z wide body installed.

whats the rest of the specs on the engine tranny

Its a 5.7 forged pistons and rods. Trick Flow CNC ported 215cc heads, BTR Turbo cam (ill get the specs), BTR 660 titanium valve springs, LS7 roller lifters, LS6 intake thru a T56 manual and 3.39 rear gears

Nice. Which 61mm turbos?

sounds like a good plan

Ive tried to find what specs the turbos are but I lost them a while ago. All I know is they are ceramic ball bearing 61mm from CX Racing and they work Damn good. Member "FORCEFED" recommend them to me few years ago for my goal of 800/850 and they have clearly surpassed that with 1,000rwhp (20pis and lean but ok) lol

Good to hear! I have twin 61's I'm installing now.

Nice results!

thats super nice! nissan chassis with a murica engine!

:thumbsup:

Super clean 300ZX! What was the timing chain that broke?!?! That is a rare failure... was it new?

yea it was a new LS2 one I believe

Nice numbers! I got a pair of VS racing 61mm cast JB turbos T3 I wanted to put on a stock 5.3 with a stock LQ9 cam. These are the $500 a pair jobbers that I got for like $450 shipped with an eBay coupon. I wonder how they would stack up besides slower boost being JB. I'm prob not looking for more than 600hp being in a 2800lb kit car.

I'm surprised the LS7 lifters were your choice being cheap vs nicer lowish priced morels or johnsons.

What size wastgates and blowoff valves are you using? Im starting to get parts for my first twin turbo build. I already have 61mm on3 turbos im going to use. Only looking for 600 to the wheels to start with. 67 buick gs400, LS1, T56 magnum.
