Headers
These headers are produced by TA Performance with research and development by ArizonaGN and are based upon a proven, unique design that has been used successfully for over six years. It is a high-quality unit, made by a leading manufacturer who has produced many types of headers and has been in the industry for years. The pipes have been specially designed and made to optimize flow with large radius bends and smooth transition joints to enhance Turbo Buicks. This custom design also aids flow at high RPM’s.
There are 3 versions of the stainless steel TA headers, one is a stock replacement which have design and production changes for better flow and reliability. The performance version is a refined design for optimum flow and velocity for higher HP builds. This set uses band clamps on the crossover connections to provide a more positive seal. The performance set is also available for 4-bolt turbos. The flanges on all TA headers are laser cut to fit either 8-bolt or 14-bolt heads.
Installation has been made simple and easy, each bolt can be easily accessed. The header pipes do not hinder spark plug access. Access to re-torquing headbolts or studs is available with slight modifications to the gasket.
On a GN with factory A/C, a 3-1/2″ THDP can easily be used with no modifications required to car or pipe.
Crossover pipe is 2 pieces with a unique, leak proof slip joint [pat. pending].
The slip joint allows adjustment for differences in type of heads and engine machining. The crossover will clear block girdles and mini-starters. The crossover to header flanges are CNC machined and both tapered for a very tight fit. The pipe/header joint has an overlap fit into the header. A gasket can be used if desired.
These headers will be sold as a complete kit, Header flange gaskets and a turbo flange gasket will be included. All hardware, clamps and stud kits will be part of the package.
The 4-bolt is offered only in stainless steel and includes a waste-gate stub pipe welded in before the turbo flange.
Downpipes
Downpipes available for Turbo Regal and Turbo Trans Am.
Our downpipes are all stainless steel construction for optimum performance and reliability.
We stock 3″ downpipes to fit 1986-7 turbo Regals and also have 3″ test and dump pipes available with a 4-bolt flange as a option.

Transmission Pans
Transmission pans are not limited to just your Turbo Buick! Call or e-mail us for pricing on almost all cars and trucks!
This bolt-on deep transmission pan is made from cast aluminum and designed with cooling fins to dissipate heat quicker. Cast aluminum pans hold approximately 2 to 4 extra quarts of fluid, thereby reducing operating temperatures and increasing transmission life.
These pans also increase transmission case rigidity, allowing more torsion twist capacity.
All necessary hardware is included (including filter extensions).
No modifications are necessary.
Increased fluid capacity by approximately 2-4 quarts depending on application.
Can use 700r4 filter with some modification call or email for details.
Transmission Converters

Modified Stock Location Intercooler
ArizonaGN offers a slightly modified stock location intercooler affectionately known as the “Nick Neck”. This intercooler starts life as a stock intercooler from an ’86-’87 Turbo Regal, the neck is then modified by increasing the tube diameter and straightening the flow of air out of the turbo in to the intercooler.
This type of intercooler is a good upgrade from a stock intercooler offering a small gain in performance and can act as a “go-between” until such time as a PTE SLIC or front mount IC would be appropriate. This is also a good option if the owner wants to retain the stock look but increase performance slightly.
This intercooler is typically in stock and available for immediate purchase. Adapter hose needed for installation is included, other stock hardware, tubing, connectors, etc. are reused.
(Pictures show modified area of intercooler. All units shipped are all black.)
Price- $275 (acceptable core required)
