so far the only "hi po" LG3 talked about is the lesabre with the 250hp n/a LG3

but to me.. 8.5:1 comp is screaming for some boost... looking at the pipes off the manifold a turbo would be pretty damn easy to mount up... I'm not talking crazy hp... but with proper tuning "stock" hardware engine should be able to make about 250 or so hp without grenading

ofcourse the fueling system is my worry on this idea... anyone know what other injectors might fit? or if the stock injectors will support 250hp?... how about the fuel pump ? maybe wth a kenne bell boost-a-pump to help?

I found some electronics of the piggy back variety that would make this possible ... and atleast thing I would share with you guys that beg for ecu mods and stuff

We have an 87-91 gen Bonneville here running a turbo. We also have someone running a standalone fuel management system

what do you need to run a turbo besides the turbo, oil lines, and the pipes?

One Trofeo guy bosted a LN3-C. Cheap, didnt do any tune in work and shortly after braging about its completion and awsome rubber laying stopped posting. When he did finally repost, engine was toast and he was parting the car.

One guy turboed a LN3-C in a 89 or 90 LeSabre for a prototype experiment. Made great power but ran lean he learned what he wanted and put it back to NA. He went on to build a turbo combination engine using L67 lower end and not sure which series I heads and manifold. Its been a onginig project that I dont think is done yet. He got involved in highly modified L67 II.

Then theres a LN3-C that was modified by a Reatta guy. Made some decent power using old hot rod methods. I guess he has since put a turbo on it but still need to iron out some detonation problems.

Havent heard of turbo on LG3-3 yet but hey go for it. Sounds like you know that it needs to be tuned in. I think you can get injecters same as GN guys can. I believe they are the same fit with quite a few different ratings. Guys that have transplanted L67 into LeSabre t-types have put the Walbro fuel pump in their tanks.

Good luck, go for it. Lower boost, low RPM' * and proper tunning is should work. not sure if more turbo acceptable pistons can be had.

so far... looking at it I could prolly do a low boost ghetto/junkyard setup for under a grand .. that'* ofcourse with me fabrication everything .. to do it properly to get the potenial out of the motor I'm prolly looking at about 2200 for everything... BUT most of that will be transferable to say a L67 swap

for the junkyard set up

- T3 from a Tbird (with the stock 6-7 psi boost control)
- 2 I/C'* from Tbird/SVO mustang to chop and reweld
- rising rate fuel press reg
- misc assortment of 1 way valves
- various peice of tubing for intake piping
- oil lines
- custom exhaust tubing to mount turbo between the 2 manifolds where they normally join
- after cat o2 simulator
- chunk of exhuast pipe to replace cat

basically with that set up your kinda counting on the stock fuel system with the MAF and the rising rate FPR supply the fuel for you.. which really it should be able to do it ...

on stock internals with the proper fuel/ignition/timing mods ... should be able to hit 12-14psi on the lil T3 with stock heads ... should boost bloody fast too

most of the addons would be aftermarket universal ... sooo I would only go that far if I planned on adding a L67 on turbo later on.. ofcourse the L67 would require a larger turbo then the T3

i would be tempted to try it on a L36 but I think our compression is too high. (9.5 I think?) Good luck if you decide to do it. I would probably get new internals that can take the boost, dont want to blow out the motor.

well if ya wanna go turbo ...just buy new forged slugs at a lower comp rate...that way your not too high for a turbo build ....why only 6-7 psi isn`t that a wee bit on the low size and does it add enough ponies and tqr to really notice ....just asking ..cuz not sure on the low end of psi ....

ha, i need a new motor first. And a new tranny... The list goes on. I wish it was easy.
