How to build a high 11 low 12 second Iroc

Stock clean car to start

MSD 8mm wires

One Step cooler (NON Platinum Plugs)

If auto (B&M Stage 2 Shift Kit) when you blow that get a TKO 500 and get it freshened up.

Balanced Drive shaft

Hardened U Joints

NX Nitrous Wet System 100 shot

Nitrous pressure Gauge

Bottle Heater

Water Temp Gauge

A/F Wideband for Monitoring Nitrous

Sport Comp 8k Tach

10 bolt rear 7.625 with 373's

Detroit locker locking Diff

Mickey Thompson Drag Radials 255/50/R16 Largest you can fit without tubbing and stock rims

Spohn Adj. Torque Arm with Drive shaft loop and cross member

BMR Adj. LCA's

KYB Shocks in front Heavy Duty Monroe's in the rear

Flowtech Headers

High flow Cat

3inch Piping all the way back

American Thunder Flowmaster Muffler dual outlet

SLP CAI

Delete AC

Take out AC radiator in front of actual radiator for better cooling

Poly Trans mount

Racing seats with 5 point harness's (optional)

No back seats because the racing seats had to be bolted to the floor

Remove front bumper support 35lbs

stock power seats removed 13lbs each compared to racing seats

Relocate batt. for the SLP Intake

All this will get you into low 12's high 11's with STOCK TPI set-up, STOCK ECU, STOCK internals.

$6,000 plus the price of the car. So 11K total for me
Stopping a C5 with bolt-on mods in it's tracks with a STOCK TPI MOTOR.

PRICELESS.


Fire jacket for the track safety inspection

Any questions comments concerns let me know!!

(1.5 year build so far)

When changing to manual you'll need a lot of time and some fabrication.
Adj. Master Cylinder
Stock Slave from manual 305 car
Mcleod Street disk
Mcleod Clutch fork
TKO 500 Trans
Spohn cross member/torque arm/ optional Drive shaft loop
Clutch Pedal Assembly
Hydraulic line
Clutch reservoir
Yoke to match trans and drive shaft


Best of All Emissions LEGAL I passed with an 86.6 out of the max 87 allotted Carbon emission.
