This has been a on going project of mine since the pass year. I will continue the write-up and build-up of this project. most of the info are posted to this site.

The Lesabre T-type Forums • View topic - 3800 S1 TURBOCHARGE / INTERCOOLER /6 SPEED....BLT... w/Pic

This project is almost finish. I will update this forum with up coming progress.

thank you.

Since my last post on the other forum i`ve been working on the Axles. The Axles are a hybrid. The inner axle CV hub from the F40 axle shaft was use with the L67 (supercharge 4t65e) shaft and outter axle CV joint.

Both sides of the axle measure 15 inch. The spline On the L67 shaft was cut off, making the total lenght 15 inches (perfect). Now the 28 spline was cut on the L67 shaft. the F40 axle tri-pod will fit to the newly cut 28 spline.

here is work completed.







Installing the F40 six speed shifter is not easy with minimal room. I was still abot to pull it off.

This is the OEM automatic shifter plate, which will be reuse.



Notice the Three threaded stud welded to the shifter plate. The F40 shifter require four(4) bolts to secure the shifter to the floor. In this application, I was unable to use the four bolt pattern. I remove one of the front bolt hole from the shifter. This is a must if you want the shifter to fit into the Lesabre t-type center console.
Before i could install the shifter here are the modification made.


This is a picture of the modified shafter mounted to the shifter plate.





This is the center console replace with the shifter securely install.



I am still awaiting parts from GM. Still have to install the shifter boot, reverse spring with botton on the shifter shaft.

This is the shifter cable connection to the F40 transmission.

The sub-frame body bushing was also replace, after 19 years. i replace the factory RUBBER (OEM) body bushing with poly body bushing from the 1989 chevy s-10 blazer.









Here a picture of the 97 pontiac grand prix AGX front struts with new body bushing, wheel are from the 1997 ford mustang (cobra 8.5x17).The brake rotor are 13 inches in diameter from the 2002 Buick Park Ave.

nice work! I bet it'll be an animal!

Considering how many of these parts are just hybrid parts from other vehicles, this is a good build just showing how parts can be interchanged across models and you don't always have to go with the high dollar items or have parts custom built. I can't wait to see what else you do to it, that is going to be an insane car. Those 3800s are almost literally bullet proof. I've seen those engines driven over by a bull dozer while the engines were on full throttle and the car just started right back up and drove off.

Thank you guys.

I`ve never lost a 3.8 due to engine failure. the 3.8 block need work in the oil department area. I find the 3800 and series`s of motor use a gen-rotor oil pump. which will maintain hi oil pressure (30+psi) even when the motor is warmed up and heavy city driving is required.

I have finalize all the custom motor mounts. Using mustang rear trail arm (poly busing).I picked four trail arm from a swap meet for $80.00

I then modified the poly bushing trail arm to work has a tight mounting.

this is a FWD application.



Rear right-side engine mount.


Rear left-side trans mount.


Front Left-side trans mount.


Front Right-side engine mount. this mount is located under the A/C compressor, and retain the factory (OEM) bracket.



The is the factory (OEM) oil filter housing next to the axle hub. Once the axle is install , You will run into clearance issue.


Here is the modified Oil filter hosing away mounted away from the axle/hub. This housing now have a lot of clearance with a ac-Delco PF-52 (long for more filtration) filter.

hey steve what injectors are you using? and do you know if the S1 L67 injectors will work in the LN3? I started my own little turbo project on a 90 lesabre that i bought as a test mule so i dont damage the BLT

You have mustang cobra wheels on a buick?

So whats wrong with mustange rims on a Lesabre T-Type? Same bolt pattern.

GM and Ford don't mix!

Yep. you are right . the rim are 8.5 x 17 1997 ford mustang cobra rim. Aluminum ,very light weight.

I am running the series II 36lbs injector. Your injector should match your ECM. The 36lbs injector is control by ONLY GM 3800 series S/C ECM. the N/A injector on boost application will run the engine lean on all condition. S/C injector will N/A ECM will cause a rich AF ratio on all condition.

Whats the injector PN#?
I believe the SI s/c injector are 26-28lbs.

I've got some 94 cobra rims in my garage. 5 lug 17x8.5. Only difference is they don't have the little dishes painted like the 96-98 rims.

On my old fox:



Sorry to thread jack.. I mjust miss my old foxy lady lol

Today, I took some time off the other project to work on my personal street machine. About a month ago i completed a machine work on the 6 speed CV/axle shaft. The center is a complete one piece. No welding of any sort.

Please be warn GM and Horsepower goes like white on bread.... welding and using other strange method will not work. The center must be machine one piece with spline on both ends.

Here are the picture of the installation..


Driver/Left side 6 speed axle install PERFECT! view from rear of wheel


Pass/Right side 6 speed axle install into Extender shaft. PERFECT! view from front of wheel.


Pass/Right side 6 speed axle install into extender shaft. view from rear of wheel


Driver/Left side 6 speed axle install. view from front of wheel

I`m so happy. i am also ready to driver over some INPORT



My next section of this project will be the install of rear disc brake for the 2000 buick park ave. Also notice the aluminum spindle from the PA or GTP. the stock lesabre feature a cast iron spindle weighting around 25-30lbs. the new aluminum spindle with hub bearing weight 8-10lbs. less sprung weight to the suspension means better control of wheel hop and traction.

I bought the cobra rime from the junk yard for $200. after i finish recondition with dupli high performance wheel coating. look brand new.


Love the touch of gold..

I had to re-design the turbo cross over pipe. The transmission shifter linkage,bracket and cable is an obstacle for the automatic trans down pipe. So the turbo down pipe will need relocating and re-position. Not much room in this area ,but i figure Thermo wrap will help with heat transfer.





The new Y-turbo cross over is more flow dynamic and can help with turbo spooling. Since the turbo is re-position the down pipe will make its exit between the rack and floor pan.



I am planning on heat shielding this area. The propose fuel line system will be use from the 1994 buick park ave. The park ave fuel is run alone the right side of the car (opposite on BLT), far away from the exhaust pluming. The PA fuel line system are plastic and will required the fuel rail from the 94 PA install to the Turbo 3800 intake. The power steering line will also be re-rout to the cooling tank inside the radiator. This cooling tank was once use to cool the automatic trans fluid.

This week on the project was decade to body and panel work. The factory paint is enamel black with clear (color code v8555). I will us the same enamel paint. The Enamel paint is easier to paint and dry fast. Its the paint of SHOW-ROOM quality, Not dealer.
Anyway ,I`m sure you`ll fine all the Con and PRO about enamel paint. I am also planning to put a sliver purl additive into the clear coat (NO SPARKLES ). Wonder how it will look?. The primer (BASECOAT) is a EPOXY primer with SEALER.













I should be painting The car Shiny GLOSS BLACK with about 6 coat of clear. Next week i will be receiving the machine 3800 series I block with balance rotating assemble (7,000 rpm). So i am hoping next week i will have this thing running.

I am also debating if i should lower the car 1/2" (inch). The front does sit higher when compare to stock. The car front end lose 225lbs due to the manual trans swap and other. The cars is now close to a 50/50 distribution. I will have the car weight at the track scale to see what changes in weight have been made.

Get a good look at the WIDE TRACK BASE l.... Sharp turns in the road are no challenge for the wide track wheel base.

another thing. In 1989 this Buick receive a FIVE STAR rating from the Insurance institute, when crash test. Not be to compare with NEW car rating.
