How to get lots of boost on a 86 lebaron 2.2L TI

[bmxrider]

i want to know what i could do to make my lebaron have more boost. its a 2.2, with a TI. the turbo is good. i already have a 14psi computer and i am upgrading the coil. so what else would i need to do?? im looking to get atleast 20-25psi of boost. is this also possible?

i dont think you can push a garret t1 that high, go to www.thedodgegarage.com and read about running a 5th and 6th injector, a rising rate regulator, afpr, adjustable wastegates and graingers
there are a few ways to get it done.

whats the cheapest way to go?

If your looking to run boost in those ranges.. I HOPE that its not a STOCK T1.. with a LOG intake.. crappy rods and stock pistons. Your post count suggests that you've been here long enough to know better than that.. unless you got all those posts spamming in the lounge!

most of it came from the lounge. but i've been reading and reading posts. is it easy to get 15 to 20 psi on my lebaron TI?

Yeah, put a JATO engine on it. No just kidding, boost controllers would push an extra safe 3 to 5 psi. It's really hard to tell without seeing the car or getting it dyno'd, every car is diffrent and so if it's in really good shape, then you'd prob. get that.

Any type of bost controller will allow you to go as high as the turbo is capable of in itself. If the stock turbo can only push 5 more than its factory setting thats all the higher the boost controller is good for. I highly doubt any stock turbo can push 20 psi, maybe except those used in the Evo's (Big 16G). I bet it's safe to say the stock turbo would be able to push another 5 psi on a single T setup.


If you want 20- 25 psi in the car you are going to have to upgrade evrything in the whole engine. Pistons, rods, crank, ported heads would be ideal. Fuel would also have to be changed out to probably 2X the limit of the stock injectors probably around 600cc and a larger fuel pump. Intercoolers will allow you to run higher boost with same octane gas to a point. Running 25 psi is going to require some 110 fuel

I know of lots of people that have ran 20 lbs of boost on their stock Garret T3. Check out this site. http://www.thedodgegarage.com/the_89...na_page_2.html
Down close to the end it says: "Epping Dragway 5/14/99, PAYDAY!" Below it says he's running 20 + PSI of boost. However, if I were you, I'd pull the motor, Convert it to TII status, put some TII Rods, and Pistons in it, then take care of your fuel system. Probably going to need +40's for 20-25 lbs. Also a BIG InterCooler, and you're going to want to upgrade your tranny to a a555. You'll need an AFPR, a better fuel pump, etc... Good Luck.

i just bought a boost controller and next im going to get the intercooler. the boost gauge is on its way. i've decided i want to run in the 11's. i just want to thank the people for telling me what i need to do. im on a budget for now till the weam weather rolls. the car needs body work and i want to get the power plant done to fit my needs. thanks guys!

if you can wait till you save up some cash you could convert the harness with a 89 harness and drop a common block in it. i got a rebuildable short block for $75 + shipping and a couple of 89 turbo mini harness's w/sensors and relays for $60 + shipping.

Also, if you have an 86 2.2. Then you have the weak Rods and not so great STock pistons. The rods are a huge weakpoint. I am only running 11 psi on my stock 86 2.2 and don't want to risk blowing up my motor.

You also have the 10mm head bolts. I wouldn't run more than 12 psi myself. You need an intercooler and stronger guts in that motor. You can have the head bolt holes drilled and taped for 11mm, but you would be money ahead to find a Tll motor at a salvage and snag the intercooler and rad with it if they are still there. A comon block from a newer 90 and up would be good, but you need all the brackets that go with them.

It's not the turbo holding you back, actually thats about the only thing in your current setup that could meet your goal...although upgrading it would help out a lot at that boost level. To run 11's and 20psi+ you're going to be looking at converting to blow through, and either rebuilding the 86 block or dropping in a common block that is stronger to begin with. The stock fuel system isn't going to cut it either, you'll need a new pump, injectors, afpr, rising rate regulator...I would rather go with a new calibration personally. You will definitely need an intercooler and a big tranny cooler. The next thing to go will be the stock a413, it's a good tranny but stock with original miles on it don't expect it to handle the power for long.
It's not going to be very cheap to do all that....you would be better off maybe converting to TII, intercooling it and running 14psi. It should be pretty quick like that, but if you're set on running 11's.....have at it.

[bmxrider]

well, i have a 14psi cal i want to use but i want to till i get a boost controller, grainer valve, t2 injectors, intercooler. im thinking with these mods, i can get atleast 18psi. am i close? also, does anybody know where i could get a flange so i can use my stock ti on the later ti intake?

i think www.******************** has them
