How to mod up an LT1?

[JwMonE99]

I know a lot about the LS1 and im kind of new to the LT1 now that I picked one up now. Its also a A4. Do the same mods you do for an LS1 be the same for an LT1? Like I know the LS1 has a bad rear so do the LT1s have a bad one too? besides doing nos, turbo, supercharger how do we get more power from the LT1 is it also by doing gears, tuning, shift kit, tq ect. ect. I hope you guys understand what im trying to ask

Pretty much the same as the LS1 but with more blood left under the hood.

start with the basic bolt ons... then go heads/cam etc. Drivetrain stuff is all the same as LS1.

subscribing... im probably buying an lt1 within the next couple weeks.

what do you mean by more blood left under the hood?

[ATCharming]

im not really sure what he means either... maybe he means it has more potential?
the lt1 block is iron, making it able to support more power than the aluminum ls1.

I'm pretty sure he means its not as easy to work on an LT1 as it is an LS1.. hense LEAVING more blood....

[ATCharming]

ohhh hahaha. i read way to far into that.

its harder to work on an lt1?

Not everything is harder. For example I found a cam swap to be much harder on an LS1 than an LT1.

there just seems to be less room.some things are harder like headers spark plugs and sparkplug wires. i own a lt1 and love it but the ls1 is the better motor they are both great but the ls1 is just more advanced. ls1 responds better to mods but the lt1 car is cheaper so in the end if you watch where you spend your money. you should have about the same money and cars be pretty evenly matched. but in the end if money is not a factor, i would def. take the ls1.

True.. but good luck dumping an LS1 engine into a 3rd gen.. compared to an LT1... (I'm in the process.. lol)

do a stall first, then heads, cam, and intake! then spray!!

We have a winner of a band-aid!

make sure youre opti is in good shape! my friend is going through hell with his 95' z.

if i had an lt1 i would go ahead with a fairly big cam and a new valvetrain because they already produce good torque down low. plus the iron block coupled with wide centers means a nasty exhaust note that would put any ls1 sounds to shame.


same basic modding path. subframe connectors are a must.
if its an a4 you could get away with keeping the 10 bolt rear and just throwing in some stronger axles...get the c clip eliminators.
certainly get gears and a stall, infact i would do that with the cam.
3.73s, a 3600 stall or looser, and a nice lumpy cam should make for a pretty quick street car/weekend warrior.

also you may want to look into the lt4 conversion...very proven and very powerful in a package deal.

stay away from slp.

Correction. LS1's are much much better when your talking cam/bolt-ons, mostly in part to the stock 205cc heads compared to the 170cc LT1's. But as I have, you can build an LTx to make 500rwhp naturally-aspirated just like you can an LS1. LTx's are very capable, you just have to build a serious motor.

correction for what...

yeah proven to be a waste of money.....

hot cam kit, 1.7 roller rockers (watch what cam you get with these), while you do the rockers you might as well take your heads off and hand port them... just follow to the exhaust ghasket lines and be very careful, electric water pump, full exhuast, rear gears (same as LS1 trans reqs), tq converter, dyno tune,

ect ect ect...
