Swap a LQ4 or Stick with the LT1?

Ryne had my heads milled to up the compression back up since i wanted an N/A build... if your looking for an N/A build, I'd start off with an LQ9 block, as it's the same as the LQ4 but the pistons aren't dished... so the compression is 10:1 as opposed to 9:1 (i believe those are the right CR specs), and there would be no need for you to mill the heads... I went with the LQ4 simply because I was on a tight budget, and Ryne had one available in his shop that he cut me a great deal on...
my current compression ratio is 11.2:1 after the milling of the heads...
fly-by-wire? that's what's on the new vettes throttle body right? the electronic throttle type setup? if so... no, mines cable, just like it was on the LS1....
everything from my LS1 swapped over by the way... so it was all interchangeable...
If your really serious about this build and want a good reliable setup, give the guys over there a call... they can set you up with one like mine or similiar to it... with a nice SAFE/RELIABLE tune...
my car could absolutely make more power than it currently is... but i have a rich tune on her because reliability was my main concern... and I'm completely satisfied with the "pull" it has right now...
from the words of Tony Mamo...
"Your graph is a thing of beauty man....nice job.
From what I can see you have perfect valve control approaching 6800 rpm's right now"

lol... Ryne, Mike, and CJ really pretty much did all the work... so honestly those are the guys to ask... but as far as I know, the LQ4 is exactly the same as an LS2 with the exception of dished pistons for lower compression (perfect for an FI setup) and it's iron...

Ya it seems like the swap isnt that hard. just take a few things of a ls1 and its good to go.

(LT's, ORY, Intake Manifold, Throttle Body)as for the heads... well, I've always wanted a good set of AFR's and Ryne came through again with another killer deal on em so...

I used to work for RKSport (which was right around the corner from BBK)... a buddy of mine over on LS2.com got on one day and mentioned his trans am was the old test car for BBK and it had been totaled so they needed a new one... the year, make, and model matched my car... so on my lunch break I hauled *** straight over there and made arrangements... plus I had previously dealt with BBK before since we sold their stuff over at RKSport... seeing as I was nearby, had the exact car they needed, and the timing was good... not to mention we had business relations with them... it all kinda worked out...
course I was supposed to have my car in GMHigh Tech Performance magazine after it was all said and done... but my stock LS1 taking a crap on me took that out of the equation...

Either way if i get my head into this, when its over i want a 409CI stroker, with l92 heads, Y92 intake, with 90mm TB. Shooting for like 500rwhp.

sounds good. You should try and get into a mag again. Its pretty sick what you've done. Dont see it all the day, or even that much a year.

I'll be upgrading to either a FAST or the new Street Warrior intake eventually... along with a 90 or 92 setup... that's really about the only area I have power left on the table except for maybe true duals and a bigger cam...
but my puny 224 cam is doing pretty good by me so far...
i don't want to loose driveability and right now it is really really street friendly so...

I doubt i'll ever run the juice... I don't like the fact of only having power when the bottle is filled up... not to mention, I'd probably get trigger happy and blow up my ****

Get the LQ4. Thats whats in my 99 TA. Most of the mods are in my sig. I just installed a FAST 92/92, and this car absolutely screams. I am on the STOCK truck motor camshaft.
I know, it sucks. But I have no more money for the cam package I need/want. Right now the car is a torque monster. Before the FAST 92/92 it was at 373RWHP and 409RWTQ.
After the FAST 92/92 I am betting I am over 400 RWHP and at least 425 RWTQ. I have 60 HP at least sitting in my cam, its eating me alive honestly. This setup is fun as hell(420RWTQ) but I really want a 230's 114LSA cam. This power was also threw a Moser 12 bolt.
Get the LQ4 if you can get it cheap. Its a really nice motor, with a slight weight penalty. Good luck

Ive now realized i should get the cam done before putting the motor in to save money/time. Im still trying to decide what would be good. And when your rocking an all iron block/heads. LQ4 weighs about 200LBS less than LT1

Wonderful info. thanks much. AND A STOCK CAM WITH 373/409!!!! what were the bolt ons? and what heads were you running?

Lq4 Iron block
Kooks 1 7/8's LT's
Custom fabbed exhaust, mandrel bent, thru a Spin Tech muffler.
853 heads ported by Lingenfelter. Yellow springs.
Built T56 by W2W before they shut down.

Not included in those numbers is the FAST 92 intake and the PTM 92 TB. Should be 400RWHP and at least 425 RWTQ. I hope.

ya those are some CRAZY numbers to get with no cam. And the LQ4 is a tiny tiny cam. I read an article where they got 58 more crank hp out of a GMPP hot cam. Cant even begin to think of what would come out with a 230's cam.
whats your CC with those heads? and estimated CR?
