Meh, could go either way. LSJ has the advantage of longer gearing and higher rev limit. LNF has the advantage of the cam timing, which can play a crucial role in how well it'll spool.

 

gearing is the other way around my friend

 

exactly lnf has better gearing better cam timing and probably more timing due to DI

least i'm not the only one who's not blinded by the almighty lsj lol .. the only things turbo lsj's have on lnf's is the 400 whp barrier and at 18 psi the person closer to that will be the lnf..

 

You do know mikes car is running 26psi right. Chris's car is still on the stock clutch, open diff, and stock axles. Mezz's car is defintely over 400whp I don't think it would be much of a race at this point

 

Oh, whoops

 

hell even if they were at the same psi i'd venture to say the ss/tc would win

 

me gusta

 

so this makes me wanna blow my 7k christmas bonus to turbo my car this winter. not good. lol

 

Well we tryed to turn the boost up and found some boost leaks so im gona try and sort them out over the weekend and then try again

 

yeah, get that crap sorted out and we'll have another go at upping the boost. At least it's setup for it so you can test it out once you go over all the piping.
I'd check that intake mani and if anything put some sealant on the flange to the head.

 

yeah from what i have seen, by the snypse car at 22psi they were only able to make 371/383 and thats on a decent size turbo, quite a few lsj's have surpassed 400 on 22psi or less

from what i understand the lsj head flows better stock for stock. i may be wrong i dont swing from the nuts of a lnf and i dont enter that section often

lsj will go 7400-7500 all on stock valvetrain

hb ss/tc destroyed his head trying to run 7200rpm on a lnf

like i said it was imo, which im entitled to have right?

 

there is no lnf nutswning.. .. just because synapse had some issues pulling the power out.. right when these cars first came out doesn't mean people are still having issues... and just because one person destroyed his head doesn't mean everyone will...

yup you are totally entitled to your opinion i just think you shouldn't make judgements based on a few situations

 

eh synapse car was only running a gt2871r.

I had my LSJ up to 8k rpm (on accident) on the stock valve train, still fine to this day (heads on another car now).

22 psi doesn't really mean much though, need to get more in to what size turbo they were running, hell I can make 400+whp on 15 psi on a 72mm turbo.... lolz




and kyle, stop with the LNF harrassment man, that's my territory.

 

hahaha sorry i'm not working i need something to entertain me lol

 

wasn't talking about on here.
I've been having some things get back to me lately I haven't been to happy about. I told you the deal when you started doing the trifecta stuff. Please stick to it.

 

Well synapse ran a 2871 which is a T2 turbo thats y they did break 400. Im running a T3 3076 which is a pretty big difference and mezz is running the 3076 also and i bet hes over 400whp

 

Garrett turbos are just too expensive for me. then again I want a FP unit which is right up there.

 

7k bonus jesus christ get me an application .
you can make a basic kit for like 2k..then there's all the supporting things you gotta worry about which is why i haven't switched yet .

 

fp's ain't bad at all, but you won't get the response the DBB units give.

 

Maybe i'll build the first fp green cobalt. I'd like to do holset style like dan back in the day, but one of those mothers won't fit

 

i did nt say your were nut swinging, i meant i dont know a whole lot about the lnf, i focus on the lsj because i have one,

but i also thought snypse was running 3071 so i was wrong there. i only watched the vid once a while ago. 2871 is pretty dinky

and agin it wasnt a judgment it was my foreseen outcome... i dont hate on the lnf i like that the block is stronger!

i totally im not gonna waste energy on the whole lsj vs lnf they both are great platforms for decent power

i was basically just stirring the pot a little by throwing out there that i personally think turbo for turbo psi for psi stock head for stock head i think the lsj will prevail

i know i flow more ve/lbs min than them... and i walk tuned lnf's easily on 18psi and ther spiking 25 holding 21-22 (yes i know 20g vs k04)

 

go with a bullseye/borwarner setup man. They are journal bearing, but spool the same if not faster and make more power than their dbb counterparts.

 

And they are nearly bullet proof!!!

google s256 vs 30r

the 30r hits harder but other than that they are side by side till the end and the 30r is not serviceable (must do a whole chra) and cost much more to maintain

 

I almost scooped up an s475 for my RX-7, but decided to lower my power goals from 750+whp to 550whp and went with a gt3582r lol. wanted the car a bit more streetable.

 

very similar indeed, minus the lag from the s256. I'd do that if I twincharged but for straight turbo i want something that would have full boost by 4500 latest.
