Nitrous 408 LS2 Build Thread
Nitrous 408 LS2 Build Thread I've already started this so I'll try to document as much of the process that I have already done as possible.
To start:
Kotzur Racing LS2 408
Eagle Crank & Rods.
Arias nitrous pistons
Kotzur Racing L92 heads
24x/25x 6xx/6xx cam
Victor Jr L92 intake
6061 elbow
NW 102 TB
Nitrous Outlet Direct Port Rail System with Dedicated Fuel System & Nano
Th-400 with T-Brake 4400 ATI 8"
SMJ Line Lock and ABS Delete
LNC-002 two step & timing retard
Mosier 12 bolt 4:30 spool
QA1 frnt / rear
TRZ Adj LCA with TRZ Relocation Brackets
BMR Tube K
Madman Manual Rack
Wolfe Cage
Im sure there are a lot of things that I left out and I will add them as I remember. I should preface this as saying that this car started out as a 2000 Trans Am WS-6. I am converting it to a formula and repainting it and completly re-doing the interior in the process.
I will post pictures as I get them uploaded.

When i had the converter spec'd I told them I was going to be hitting that converter with a 250-300 single stage. ATI told me it would do just fine. I also had it built when the car had less HP and weighed more, so it should be just a tad tighter as well.

Have you contemplated more cam? what is your compression and fuel choice? the 240s/250s stuff is very torquey in the strokers , I like to run more lift and duration with them, late 250s intake early mid 260s exhuast, .700 lift, if you want to rev them up a bit. The LSA requirement really depends on what your static compression is, to a degree. The reason you need wider lsa in the plastic intakes is more to do with the average airspeed through the runner. I would port the victor junior run more taper and keep the LSA on 108-110 even though it is a nitrous specific engine. I have run 106 with those intakes on 6L and they pick up.
I thought about stepping up the cam before the build somewhere around high 250's/ high 260's Mid 600'/600's on 110-111. But I didn't want to push the limits of a LS2 block twisting it to almost 8k on a 300+shot. So i decided to keep it around 7400-7500 on a 250 shot. This should be plenty to get me into the mid 9's. My C/R is 11.6:1. I still want to run pump gas N/A and C16 or Q16 in the Dedicated Fuel System for nitrous.
