Good product Alert :

Doing this post for Jon @ Boostliner. Hood liner turned out real nice . This was the 2nd one shipped. There was a problem durning the shipping and the liner got damaged. Jon stood behind the liner and sent another. 2nd had a mark from the protective plastic on it but easily came off with some goof off . Great communication with Jon and he has a quality part for out cars . Turned out great on Julio’s 1984 GN . The liner is a fresh product and I’m sure things will be done to make it even better . 👍 all a process folks

Getting some smaller jobs off the list-while waiting for parts for larger jobs.
James B brought his 87 GN in for some exhaust leaks. Installed some TA replacement header some years back and a crack developed under the turbo support. They are a solid header but once in awhile you’ll get an issue .
No problem I got things rolling and headed off to fabricator for welding . And I re surfaced the flanges . Along the way I noticed blue goo coming from the coil/ module. So we agreed to fix that problem as well. New ac delco coil and module , plugs and new wires as well. While it was in I got some new window fuzzies on the car. What a difference 👍. More to come on this car.

Bonus: Wanted to do a post just for big job on the center rack. Jose’s 87 GN that floated a valve after a new engine build. After we determined what was going on , it began 👍. He wanted a transformed car. So here we go. Holley Dominator efi going in , all new exhaust, all new fuel system , new steering , new axle, upper tubular a arms, new transmission stage 1, powder coated engine parts thanks to Scott Coates/ Son by coates , body bushings, all new brakes, new AC system plus more.. going to look great when it’s done . I’m into it right now. Doing 1 job at a time . Can become over whelming with everything but I like these jobs . Really transforming the car. I’ll be showing pics of the rebuild of the car going forward. Follow along with the build👍

Mike’s car back to life!

04/24/2026

Another GN back running and on the road soon. Mike from San Antonio brought his 87 in because it was running terrible. Sat for years, bad work and neglect . All equal an unhappy Buick forsure. Did a new customer 5 hour check out on the car . Vitals ( compression, leak down , oil pressure)were good on the engine but everything around it was and is in despair.
Fuel system was a must and a complete system is what it needed. Then a new ignition system was in order to try and build a base on the car. Happy to report it’s running much much better. Has a driver header that was fixed years ago and now is cracked again. Definitely needs more work all the way around the car, but one step at a time .

Some Ford action this week: 4r70w
Over the last week I snuck in a build .
Love building AODE, 4r70w family transmissions. Ben brought in his 94 Tbird for a needed trans rebuild, rear main seal, drive shaft ujoints 👍 etc
This build was one of my quality plus builds with upgraded clutches and a Transgo hd2 kit.on these units I always install new forward & direct drums for breakage/ wear issues. Upgraded Exedy carbon clutches , new rubber seal kit, trans go AODE HD2 kit,
New quality converter, turned out very good 👍
Thanks for the support

87 GN TA motor

04/11/2026

Getting caught up on my posts . Busy busy here. Major job Jose’s 87GN is waiting for parts . Big job upgrading the car for today’s dependability and performance. Be doing a write up soon . Holley Dominator system , total new exhaust, new roller camshaft and fixed head after valve float, total fuel system .Plus much much more.
Next Tom’s 87 a street strip car from the 90’s with an all aluminum TA Perf engine.
Seeing the light of day for the first time running on its own for 10 years or so. Sad story with a lot of bad previous work done on the car haunting its run-ability.
Julio’s car will be returning soon for some high end Holley work as well waiting on parts. 12.3 Prodash , dominator , boost control, m**h control etc👍
Mike from San Antonio is coming in also this week for a new customer 5 hour check out and plan for car.

First Tom’s car, a job from another shop that was there forever. Partially because there being an issue with the first build of the TA block and then having no one to finish and fix all the areas that need attention. Had an old Speed pro ecu from 2000 and wiring to match. Wasn’t working correctly. Battery bad, then starter bad, then fuel pump bad. Because of years of neglect it snowballed
So :
Holley Dominator ECU
Caspers Harness
Smart coils
Caspers stock location coil bracket
NTK Wideband
Exhaust down pipe modded to fit properly
GN1 exhaust
New battery
New lt4 starter
Racetronix complete hellcat fuel system.
New regulator
New pump assembly
New Ptfe lines
NVU Dash
Etc
Got the fresh engine running good . Possibly more to come
