The EA81T is MPFI - can't use the Weber on it. With a Weber and no other mods, your not looking at much HP gain at all - under 10 if that..... MUCH more low end torque, but the high end doesn't change really.

The EA81 stock is 73 HP - the EA81T is 95 but lacks the low end.

Again - try out the search function as these topics have been covered in great detail many many times.

are you asking how much hp that will make, or how to make more?

I'm guessing it will make around 90 hp with it all said and done, but the better throttle response will make it feel like more.

if you want to find more parts for more hp, such as cams or whatever, theres a bunch of aviation sites that make ea81t parts: http://groups.yahoo....p/airsoob/links

good luck...

I know the ea81 has about 73 stock, turbo 90- 95 .

If this is for your rally vehicle then the high end HP from the turbo is the ticket. If it's for an offroader then the webered EA81 is the way to go.

EA81stock=73hp
EA81T stock=90HP

EA81 with weber and exhaust=est. 90HP
EA81T with airbox mods and exhaust=guess110HP

The thing to consider is the torque curve. If you are running wide open rally type driving the turbo will stay in the power curve and produce power there. If you are running off road where the RPM's are lower then the the Weber is where you will see the most benefit.

Trying the search function brought up quite a few topics. Some relevant and some not. But it should make for interesting reading.

These are the posts that Weber found.
And the EA81T*

gonna put the Weber on 1st, to complete 'phase 1' (82 GLW)

-work done (phase 1)
Accel Hot Coil
7.5mm wires
1.75" exhaust from CAT back to Turbo Muffler
KYB suspension
RX/xt? 22mm frt sway bar
vented frt discs
rear discs

-to do (phase 1)
32/36 DGEV weber
RX/xt? rear control arms w/ sway bar

phase 2 (got everything except time curently, ha ha ha )
-refurbish/install EA81 turbo (hhmm, maybe w/ some aircraft bits?!)
-Full Time RX 4wd 5spd w/ D/R & ctr Dif & LSD

I guess I'll have get Snow White into the Gallery, she's real pretty!!

cheers

I would just use the 4WD D/R 5sp. The RX trans is a 3.70 and the gear ratio makes it more for highway then for rally type driving. The LSD can be changed to a 3.90 ratio.

Again, just my opinion.

Shan. I got some nice Accel 8mm wires you can have. Bought a set for a V8, so i have 4 extra's that would work better with your coil.

The EA81 with weber will be better for you. You might as well hand that EA81T over to me

My EA81T gives me 120HP atw running 10psi boost.

has EA82 turbo, Top mount intercooler, Wolf3d computer.

next is an airbox (currently just a POD sitting back in the "spare wheel" area) then maybe a front-mount intercooler then bigger turbo.
