I'm finally going to make my move this coming January/February. I've had my 87 Buick since 2004 and the time has come for me to build up the car the way I feel it should be. I am seeking advice on a few different aspects of building a high performance "109" (25526109) turbo buick engine in the...

I purchased this car in October 2009 for $5,500 as a project car. It's a little dogged out from the previous owner but still looks pretty good inside and out. Power windows/locks/trunk release all work. Factory tach and boost gauge work with no dead LEDs. My intentions were to fix it up and use...

Hi Everyone, I'm trying to figure out what size main bearings are in my engine. The bearings are all original from a previously unopened '87 109 block. It's pretty clear that main 1 and 3 are .001 bearings (is that undersize or oversize?). As for the rest I'd just be guessing. I've heard that...

Does anyone know where I can find an entire driver's side T-top (Glass & Assembly) or does anyone have one they wouldn't mind parting with?

Hi, I just purchased my second Turbo Buick. It’s an ’87 Grand National with the typical badly leaking T-tops. I want to replace all the weather stripping the right way. I’ve read on the forum that anything other than genuine GM weather stripping isn’t worth it but the only GM weather...

I'm considering installing a hydraulic roller cam this spring "if" all goes to plan. Even if I don't get a chance to do it, I'd like some direction for getting a cam that matches my setup. I'm looking for something that will give me a better 1/4 mile ET and give me room for more power in the...

I've just finished a head gasket job less than a week ago with great success. The engine's been running better than it ever has. One day after I re-torqued the heads (this may not be related to the issue), I'm starting to hear a RPM dependant tapping/rattling noise from the engine under a load...

Hey guys, I just finished my first head gasket job. I used RJC Bullet Proof Head gaskets (.030 thicknesses) with ARP Head Studs. I was very meticulous about doing the job as perfectly as possible. I ran the car and drove it around for about 15 minutes. I'm having two questions/problems...

I'm considering going with a dual radiator fan setup for my Turbo T. I have a Precision front mount and the charge pipe from the turbo comes very close to the fan as it is (within 1 cm). What dual unit fan fits best with the Precision front mount setup?

When using APR head studs, I see many threads instruct you to remove the black oxide coating on the threads. The ARP instructions don't mention anything about this step. The only reason I can figure people do this is possibly so the thread sealant bonds to the threads of the studs better. Is...

I've been looking around for a T-type wheel center cap to replace one that fell off of my car while cruising. I'd buy them as a set if necessary. It'd be nice to have a some spares. Does anybody sell them as New Old Stock? All I've been able to find is the caps for GN wheels. Thanks

This problem started yesterday after installing a Cardone remanufactured LS1 MAF. I've heard that these are often bad out of the box but I don't want to jump to conclusions until I hear from you guys. I had high BLMs that were being caused by my ported descreened LS1 MAF. My BLMs were pegged...

I'm looking for an aluminum core support from someone willing to ship it. I'm willing to pay around $350 shipped. Paypal is preferred. Thanks!

I imagine the MSD DIS-4's would allow you to gap your spark plugs wider. Does anyone know what a good baseline to start at would be?

I really like the idea of fitting the 275/60R15 Mickey Thompson ET Street Radial on My Stock T Wheel. I see a few people on the forum have done this but they don't really mention how they deal with the clearence issues against the frame. Using the 235/60R15 I could barely squeeze my finger...

I've been using the P275/50R15 26" tall MT ET street radial. I'm almost running out 3rd, trapping at 117mph. My best 60' was 1.73 while pedaling a 4psi launch. I've decided to move up to a 28" tall tire. Other posts I've been looking at say that the 28" P275/60R15 MT ET street radial is the best...

I just found out that a Chevron a few miles away from me is now offering E85. I heard that E85 is a mix of 85% ethanol and 15% gasoline. Would that be a good alcohol to run in our cars? I've never heard of anyone mixing alcohol and gasoline. Just alcohol and water. What do you guys think?

Ok, I'd Like to set up my BstC boost controller to step boost down in 3rd gear and Overdrive. This sounded simple enough according to the instructions, however there appears to be a problem with the 3rd Gear signal/ground from my ECM. I cannot get it to change to an ungrounded state. I've...

Hi everybody. I've just recently removed my air conditioner and heater box from my Turbo-T after the compressor developed a bad rattle while the A/C clutch was engaged. I had some problems to which I could not find answers to on this forum. I just wanted to do my part to contribute by posting...

I've been looking around for a good aluminum radiator that only includes an oil cooler, NO trans cooler. Does it exist? I've only seen radiators that come with transmission cooler only, oil and transmission cooler, or no oil and transmission cooler. Thanks
