no rust no collisions. Thanks for spreading the word, I really appreciate it.

The car is a 1986 Buick Grand National, It has 165,000 and still runs very strong. I have installed a TA-49 Turbo, 60 lb. injectors, Turbo tweak chip for 91 octane, Walbro fuel pump with hotwire kit installed. Car also has a autometer boost gauge installed in an a-pillar pod, there is still an...

At pinks in Tucson they picked 16 mid 12 sec cars. I was one of em. I made it to the final four in my Dodge Dart. Fun stuff

I'm kinda new to buicks. I have however read about some people whose pumps have gone bad not long after install. Is your fuel pressure going up 1:1 with your boost? any chance it could be false knock??? just some ideas. hth John

some random ideas. Bad fuel pump clogged injectors fuel pressure regulator. maybe your car is leaning way out. just some ideas good luck. John

not sure if the tranny is a reman, but the converter looks pretty fresh. whats a brf valve body??

Well, I made some headway today. my dad is welding my drivers side header, the passenger side header didn't have any cracks, but the crossover tube bolt did break of in it:mad: grr. that was a pain to get out. should be running again tonight. I also checked my converter. it says 6B on it all...

how can i verify d5 or d7? its a good sized crack but i dont think it is robbing 750 rpm of stall from me.

thanks alot man. since my jury duty was postponed tomorrow and i got the day off work........ i now have some time to turn some wrenches. also i just brake torqued my car to get an approximate stall rpm. i only got to 1750 rpm, keep in mind this is with the gas pedal to the floor, no tire...

Mine was kinda tight. all i did was pull crossover, t.c. cover get the crank in the right spot. i had to drag the back of the pan lip across the flexplate for the last quarter inch. not bad by any means. John Oh yeah, i used a blue rubber felpro gasket with a touch of rtv at the front cover...

thanks for the info guys. im going to get those cracks welded up and get the scanmaster numbers in spec to insure the engine is operating correctly. I can see the crack on the d side header. where does the passenger header generally crack? I dont want to pull the pass. side header(pulling...

my stock torque converter will only stall to about 2k rpm. i have a TA 49 Turbo on my car so i start to get power at about 3000 rpm. I thought that the TA 49 was supposed to work with the stock converter. On the foot brake i cant build any boost. In conclusion my car is a dog off the...

Thank you very much guys.

which other vehicles came with the same water neck that an 86 grand national came with??? Mine got a tad mangled upon removal and needs replacing. Thanks in advance, John

I live at broadway and camino seco. Any help would be greatly appreciated. pm me your phone number, or direct email if thats ok with you. Thanks

I just now started acquiring speed-parts for my new ride. I am looking into chip and injectors at the moment, prolly gonna go with TT. i have a scan master 2.1 it shows between 800 and 850 mv while in boost. the FPR is a stock one, i dont know if there is a way to turn up the fp. maybe i need an...

I am running a completely stock setup with the exception of a TA49 turbo with a garrett exhaust housing. With only 7 psi im hoping that that is false knock, or maybe just picking up an exhaust leak or something. the car doesn't feel like its laying over or anything, it pulls fine once boost...

Give this a try. Pull the elbow and look in the down pipe. The down pipe will most likely show signs of oil if the center section is leaking into the exhaust side. When my turbo went out there was oil in the intercooler, MAF, up pipe, down pipe. it was nasty. lol HTH, John

TTT, I need to know whether this is a good tap point. Also down here in Tucson we only have 91 oct. even with that being said i still shouldn't be getting an occasionaly 10 degrees of kr should I? especcially on only 7 psi. Thanks in advance guys, John

I have gotten my 86 Grand national running, i am having a few issues with boost level readings. i have tapped my auto-meter boost gauge into the vac/boost line going to the charcoal canister from the vaccuum block. so this should be an accurate boost reading. any way my factory boost guage reads...
