98 Camaro 370CI T76 Build up A quick run-down of the build up of my car when i bought it in 2007 - It was a bone stock 1998 Camaro Z28. I purchased it as I've wanted an LS1 camaro since I was in high school. Coming from an import background, I've had turbocharged vehicles since 2003. Curious on what an LS1 would do underboost, I had built a phamspeed style kit that used stock manifolds- However the tubes sat very low and often hit the ground at SLP spring height.
The first setup had the following-
SPoolinperformance Stock manifold under-member cross over pipe- custom built
stock block
LS6 Intake Manifold
Professional Products Fuel rails
MasterPower T70 96 AR P-trim Turbo @ 8 psi
60 Lb injectors
Walbro Pump
Tuned by Nick @ NewtechPerformance on HPTuners
SixSpeedonline built T56
Textralia 0z700 Z-Grip Clutch
stock rear end
with more boost @ 13 psi we made more power but maxed out the T70 turbo
After wanting more boost- I'd install
built shortblock- used beat up purchased for 1K
Tubular Turbo manifolds built by a local shop Spoolinperformance
4" downpipe with 4" E-cutout to 3" downpipe to 3" turboback exhaust
Boost dependent SX Fuel pressure regulator
Patriot stage II ported heads with OS valves
Newtech 232/234 5xx/5xx 115 LSA cam
BorgWarner T6 S475 Turbo
Dual Walbro 255HP In-tank pumps-
Turbosmart Boost Controller
AEM methanol injection kit
Griffin Radiator with custom hard pipe coolant pipes
Custom SP alternator Relocation kit
ThunderRacing coilpack relocation kit
LS1tech sponsor 99blanco custom length MSD ignition wires with 90 degree boots
SJM MFG ABS removal kit with Hurst Linelock
this setup made Great power but sadly the bottom end did not hold up
754 WHP @ 11 psi
After some blow by issues I had SP fabricate a catch can setup for both valve covers
Fast Forward a few months.. During some racing we spun 3 bearings and realized we had a hole in the #8 ppiston due to a clogged meth nozzle- We had installed a check valve from devils own meth injection and it restricted the methanol flow greatly which affected our tune in a BAD BAD BADD way . -
a newer setup with nicer collectors were made to replace the old tubulars and fully backpurged. This time I'm going with a 6.0liter built LQ4 Iron Block.
LQ4 370 Block- balanced blueprinted
Wiseco 4.030 Bore 8.7:1 Compression pistons
Eagle rods
Stock crank
Clevite rod. main. and cam bearings
LS2 timing chain kit from ls1tech sponsor Yank
Same newtech performance comp cam shaft
cleaned up Patriot heads - new 3 angle valve job
Mcleod RST Twin Disc clutch- fully balanced with Flywheel
Moser 9" rear end from LS1tech sponsor JAWSGEAR
we're going a single walbro in-tank feeding a Bosch 044 fuel pump with -8 Feed line to the rails and a fuel lab regulator
Rebending Linelock and all brake lines to route cleaner
New Spoolin Crossover for T4 based turbo + single 44mm gate outlet
4" downpipe to 4" cutout with closed loop slip fit dumptube
T76 Q-trim Masterpower Turbo * missed the great midrange from the smaller turbo. Hopefully we hit 800 on pump 91 octane gas with methanol injection*
Lingenfelter 2 step module
AEM UEGO Wideband Sensor
Heres just a few pictures of the new build up

Thats cool. I did it in my wifes NA car and am putting in a mojovie (sp) heater box on the inside. I may do the same to my turbo car. I love the clean engine compartment.

I work nearby SpoolinPerformance. Its a local import shop and I know the owner very well. Practically grew up with the guy. I ordered all the parts and he built me the headers. basically weekend jobs the owner and I both fabricate for the car since its kind of a joint project type deal. I help with R&D parts on my car because he focuses mostly on the import items. The pictures of the ceramic coated manifolds are cheap edelbrock merge collectors- not so great for fitment because it gets REALLY tight. The pics from the last set of headers are collectors are MEGS cone collectors from Columbia river mandrel bending in oregon. Good guys, great prices and fast shipping.

4th actually . I had an OFI setup on there that fit horribly, hit the powersteering and hit a lot of items in the car, we jigged the header and made the modifications needed and started building off of that design to get the correct dimensions.
Everytime I pull the motor out or change heads/ headgaskets etc. I tend to sell the old kit and build something else to help fund the " fixing" of the car

after great results with the masterpower T70. I decided to go back to an MP T76 Q trim. my powegoals for this setup with the T56 6-speed is only 800 on 91 pump with 100% meth injection. Anything more than 800 is an issue with the transmission. Plus my clutch and fuel setup is limited to about that power.

2 valve covers to an oversized way too big catch can ( i had tons of blowby with the last motor and well .. a lot of extra material) 1 outlet that goes to the intake of the turbo and 1 that goes to the racetronix E-vac kit that also pulls vac out and blows it back into the turbo intake
