98 T/A LS9 Swap Questions

**317Born** · 12-21-2008, 03:02 AM

Ok so I received a call from my dad about his 98 t/a blowing its motor. It was pretty much nothing but bolt on's...intake, exhaust. Well sounds like my lil bro was hotroding it and sent a rod thru the block. So my dad is giving me the t/a. I owned an 02 SOM T/A a4 but ended up trading it in due to the fact that I am living in Alaska for the next 2 years. So basicially im trying to find out all the info i can on doing an LS9 swap for when I move back home to Indiana. So anybody with any suggestions, prices, or advice from ppl that has already accomplished this. Feel free to commit.

my guess is that it will cost you at least $20k.

If it will even fit in the F-Body.

**317Born** · 12-21-2008, 10:09 AM

Yea I kinda figured it would be that much. Prolly a waste of time building and dropping a LS9 in it...maybe I'll just pick up an LS2 and build it up

402/408 iron block and you can do what ever you want to it, thats what i would use

Sounds good...but 2 tell you the truth im looking for mad ponies....somewhere from 650-800 all from an n/a engine...my max budget is around 15 grand....and it has 2 still be streetable...plus have all the street essentials...of course its gonna have a cage and I would like 2 keep the back seats for my future kids...I saw a z28 with a cage and its rear seats...owner said all u have 2 do is unbolt a bar and ur good 2 go

luos is pushing 531+ RWHP with a 402 n/a with about 6-8g's in to his enigne ( i think.. lol ) so with the rest of the money your going to need a rearend/ full exhaust/ tune.........etc

dont know what trans your run if a4 you going to need a built trans with a stall

**317Born** · 12-21-2008, 10:59 AM

Yea I checked out his ride...seems like thr 402 is the motor 2 choose...im planning to build the motor. Prolly go 2 lingenfelter for most of the parts since there based outta indiana...im gonna get a built t5 trans...prolly go with a 12 bolt rearend with some 4.10s...I'll have around 15 grand for this entire build...I will not cut corners...nothing but the best will go into this t/a

LS9 isn't N/A.

If you want an insane N/A build....get the LSx or Warhawk block and go 454 or something.

Isn't it the LS9 that comes in the new Z06's...or is it the LS8...maybe I was mistaken...I think I have come 2 a decision...find a ls2...do h/c/I, heavy duty oil pump, full exhaust, built t5 trans, subframe connectors, fully adjustable suspension, c5 brake upgrade, built 12 bolt rearend with 4.10's, upgrade fuel system, upgrade ignition, tune, wheels, tires...15 grand 2 do it all...lets see if I can make it happen

LS9 is the supercharged Corvette ZR1 motor.
LS7 is the Z06 motor. 427 cubes.

The LS2 is 364. Built it to a 402, and go from there.

i've been outta the LSx world for 4 months and forgot almost everything i have learn. Epic Fail.

But that sounds good. I'll start searching for an LS2 or may even go for an LS3. Should I just get a bare block and pcm since im swapping almost everything in it anyways?

**Mr. Luos** · 12-21-2008, 07:34 PM

I am running the stock PCM with a 402 myself. Granted, I am using the LQ9 block.

The LS2 block will require a small harness adaptor to fit to your stock PCM because of a few minor sensor location changes.

oh ok...is there anything else i need 2 worry about

**Mr. Luos** · 12-21-2008, 08:36 PM

Like what?

Getting the right combo will take plenty of research. Took me a while to get mine set-up.

Otherwise, the LS2 block will bolt right into the F-Body. The outside dimensions are the same as the LS1. Just has a few different sensor locations. And obviously will require a good tune.
