i wanted to know if i could use the lnf block on a 07 but i know i cant used the head or the pistons from the lnf because of the whole direct injection. but can i used lsj pistons in the lnf block and put a lsj head on the lnf block?

 

an lsj/lnf frankenstein? lol

 

O.O

That's a hell of a question man.

Lemme see if I can't find something out for you....

However, I don't think you can. I believe the head is built completely different as well because like you pointed out. The direct injection.....



Possibility of a pretty nifty thread though if the idiots of this site stay out of it.

*waits for Jimbo, 06Black, Area47, 06Blackg85ss and others....*

 

first off, WHY? both blocks are nearly identical , the lsj pistons are higher compression though. all in all, I see no reason to, the lsj block can support more power than you'll ever make

 

yupppppppp

 

You don't know how much he made prior to a boost spike do you?

 

How fast would a supercharged lnf be....

 

He's running a precision 6262.......

 

doubt hes on the + side of 800

slower, less boost and lower compression although TVS would benafit

 

Mid 400's or higher IIRC...

I forget his numbers.

USDM...

Apparently ZZP did it at one point and stroked it...

Trying to locate the thread.

 

oh ok cool thankz

and yea i been between 440-460 putting boost up and down until i got a bad greddy boost controller and i over boosted the car and crack the block in the water pocket

 

It is the ZZP twincharged car.

Pretty sure they offer it for sale.

 

ECOTEC BUILDERS GUIDE THIRD EDITION PG 29 states that all production ecotec blocks (L61,LSJ,LE5, and LNF) are safe between 400-800hp. for power levels beyond 800 use GMPP block XGH679

unfortunately overboosting throws all that out the window

 

Well they did

When will people actually learn that you can't put a horsepower rating on everything?

 

You can thank this man right here.

He told me what I relayed to you.

 

this could be an interesting thread? subed to see what happens

 

its not the HP that did it in. just to much pressure, actual kind of shocked you didnt lift the head first.

 

he's probably studded

 

yeah arp studs and cometic gasket

did you read his post? using the LNF block with LSJ pistons and cylinder head. IIRC the lnf is a gen 3 ecotec block which is stronger in some areas

 

bump for a answer

 

i'm pretty sure you can richard. the bolt patterns seem to be the same

 

Ryan's car was actually running a stock LSJ bottom end. However, he will be running a ZZP race motor this year.

Yes you can run an LSJ head on an LNF block. The LNF block is stronger.

 

sub'

 

i thought you couldnt due to vvt and the oil passages for it? does the lnf and lap have the same block?
