Official Turbo LSJ thread!!!
#3551
I just wanted to make sure I wasn't missing anything. So I should be fine running about 400whp with that setup I said earlier and then if I want more power look into getting sleeves and girdled short block is what your saying basically? ok thanks exsoccer appreciate the info.
also i forgot about it till he posted. if you feel like shipping your block mr b can sleeve it for you with a better than stock, stock replacement.
B i know you've installed at least one set. anyone thats making some good power?
#3552
ive got 2 blocks done building one them then I can start on mine and 1 set sent to canada
#3553
Oh ok sleeves or girdle. Ok well I gotta wait til my car doesn't become my DD anymore haha. Does anyone know why I can't get wiseco pistons for my car and have to get the off brand from zzp that are even more expensive haha?
#3554
j.e. pistons isent an off brand and its not an off the shelf piston it is a custom piston made for zzp you can get wiesco pistons for made for around 160 a hole or get a set of diamonds for 400 which are just as good add around 150 for rings
pistons arent just drop in either

wiseco pistons are designed for the lnf to work with the DI. the "off brand" ones you're speaking of are JE pistons. you can run JE or Diamond in the lsj. I'm running 9.0:1 JE's with Pauter rods. bullet proof.

let me know how they turn out. are they just 2.0L sleeves or 2.1L as well. what is it like 86mm for 2.0 and 88 for 2.1? next time i rebuild i'm getting rid of the 2.0 since i'm still on a gen 2 block. want to go with a gen 3 2.1. but i'm doing some other stuff as well. so i wouldn't mind having some of these sleeves for that extra security.

Import no that sounds spot on. off the top of my head though i don't remember at what boost level and power the stock sleeves tend to fail but i would look in to that. 500hp on a 256 is going to be around 27-30psi. while the pistons and rods you're doing will get you over that, thats a lot of pressure for stock sleeves. but like you said. for now you just want to run 400. which is more than do able on stock sleeves. but before you turn it up i would start saving money and look in to a girdled short block, or just staying around the 400whp level
jonathan is correct in answering your original question. "if you left the core/block stock, internals stock and added the trubo setup would it make more power then a fully bolted LNF"
yes a turbo lsj will make more power than a bolt on lnf. a bolt on lnf on e85 or an e blend tune will top out around 370.
but with that comes my post about turbo size lol. the ko4 has a crazy soon powerband. if they hook up, they're gone. thats where choosing the right sized turbo really plays a major role. sure you can compare peak power all day long. but i'll take a 375whp car that sees full boost at 3,200 rpms peak power at 4k and carries it out to 7500 over a car that makes 420whp but doesn't hit full boost until 4100 and peaks at 5,500 or 6000
(those examples are not lnf/lsj/ko4/etc
specific. just power band in general)

you have a .338 differnece in stroke lsj shorter
both have 85mm to 86mm bore
and the sport compact build book 3rd edition they recommend and put a set off lsj rods and diamond piston combo as a hop up to a 2.2 so why cant you go backwards
