i have a 03 lq4 block but ive changed out the pistons to new lq9s also hve a set of stock l92 heads i just wanted to know what all i need to finish my swap

so far i got heads intake ls2 fuel rail and injectors 90mm tb maf and ftra lid

i know i need the map adapter but is that a good idea using ls2 injectors? also what cam should i go with????

 

L92/LS3 offset intake rockers
L92/LS3 rocker stands
L92/LS3 4.065 head gaskets

Flycut the pistons now so you aren't limited to cam choices.

LS2 injectors are probably not going to be enough, you might want to get them resized if you what some good power. Call FIC, http://fuelinjectorconnection.com

I am running am EPS http://www.engpwrsys.com/ custom cam right now, I did not get it to the dyno or the track in time to get any numbers, our weather went down the tubes.

I have a 234/236 .602/.606 114+3. These are Geoff Skinners proprietary lobes from Comp. I street tuned it and this thing runs great. I had to bump my injectors up because my duty cycle went from 80% to 97%, they are now back at 75%.

 

why do i always see intake rockers what about exh.? also what are price range for some ls3 valves? ive read they are lighter and i dont mind flycutting i want to be high 400s if possible with major tq through my th350

 

Because of the size of the intake valves in the L92/LS3 heads, the intake rocker is offset shaped so it can reach over to the valve stem. The exhaust is in the same location as the regulator LS1 type head.

The Ls3 valves have hollow stems making them lighter. Try http://sdparts.com for the valves.

 

ygot ya......would i be able to use same rocker bolts or do i need different ones? one more thing..... pushrods i dont have a checker but im i going to need another set i have tsp harden

 

The bolts are fine. Yes, you will need new pushrods, or at least check them to make sure.

 

so bolts r good and ill have to check the pushrod length what are the chance of me using a 7.4 again...also i pulled the the fuel rail and injectors off my ls2 intake and the bolts are short they dont seem to mount up correct there is like a space between the fuel rail bracket and intake any idea?

 

Katech has a fuel rail spacers kit for adapting the rail to the intake.

I think they are Katech.com

 

i thought the ls2 would fit on the l76?

 

You may be right, I can't remember for sure.

 

lol ur the only guy whos delt with this kinda stuff i guess lol

 

Not everyone on here actually does all of their own work so the shop would know, not them.

 

lol i think ur right by breaking thing and rplacing them is the only way u learn to do things..... lol
