LNF or Turbo 2.4L
 
with full bolt ons and tune, what would be the fastest? would i have to build the le5 internals or is stock good to handle up to 25 psi? what would take more money to build up, i already have the 2.4l so thats where i would save the money right off the bat, rather than sell it and buy a LNF. this is so i dont go and spend money on exhaust and shit then end up selling it all and losing money

I believe you would need pistons to sustain that on an LE5, IDK about the bottom end though. The LNF has the oil squirters on the pistons for the boostage heat and we still cook pistonies at high boost & IAT2's. The bottom end has held 500+ HP ala ZZP.

Edit... An LNF swap would be a nightmare with the different ECM/BCM combo than you have. Build up yours even if it can't get to 25 psi.

DiabeticKripple 03-28-2011 01:14 PM

i wouldnt lnf swap, just buy the car............ bumpage

whyyoumadson? 03-28-2011 07:41 PM

buy an lnf...... to substain boost levels like that in the 2.4 you need internals, intake manifold, probablly some head work, good tune, and all the extras....

DiabeticKripple 03-28-2011 08:30 PM

i should say if its going to cost an extra grand to beef up the internals on the 2.4L and in the end it will be faster, i will do that. only if its going to be like 2-4k more then i will just buy an lnf

kxrida2000 03-28-2011 08:36 PM

id say do the 2.4..my 2.2 would whoop on 95% of the lnfs and i have like 12k into my car including the car and ALL mods

alleycat58 03-28-2011 08:45 PM

Honestly, it's a judgement call. You do get some upgrades going with the LNF, but you're going to take a pounding on resale value on your car. I'd say work with what you have if you're happy with the car.

DiabeticKripple 03-29-2011 03:57 AM

i could just drive the car until it dies

cranemaster 03-29-2011 04:11 AM

If you have the ability to turbo a car, do it? What reason would you not?

Like people said, work with what you have and end up with a unique ride.


myself, even though I have a garage and tools... couldnt deal with turboing a non turbo car.

This is why I sold my 2004 Civic SI and got an LNF.

Boosting a car not designed for boost takes a decent bit of time and effort. In my case I cant even afford to be without a vehicle for more than a day.

Your call though, I like boosted 2.4's.. remind me of a SRT-4 XD

DiabeticKripple 03-29-2011 04:24 AM

thanks for all the input guys, but no one has told me what is faster in the end

whyyoumadson? 03-29-2011 08:14 AM

because it all depends on how deep your pockets are and if you on the k04 or big turbo at 25psi. the lnf will have stupid fast spool and is a better all around car. it has better trans, suspension, engine and will hold its own unless you drive like shit

mrgrinch 03-29-2011 08:39 AM

Keep us updated on what u do, I plan on turboing my 2.4 one of these days, thought about the lnf but the 2.4 would be original

elecblue06 03-29-2011 11:58 AM

wait why do you want to have 25 psi on a 2.4? i can tell you off the bat a 25 psi 2.4 will be faster then a stock turboed lnf assuming you pick a smart turbo..

shit to reach stock turboed/ bolt on / tune numbers for a 2.4 youd probably only need a proper sized turbo and 15 psi and if you have a 06-07 then you'd be fine on stock long as you have a good tune

personally i'd rather bigger displacement, standard port injection and vvt instead of DI smaller displacement and vvt lol

might you have to build the engine.. if you're looking for over 400 whp on a 06-07 2.4 yea. but shit i'd probably still build an lnf if i was looking for those numbers just to be safe

stonny9 03-29-2011 11:59 AM

A local member has a turbo 2.4 with the zzp kit and air to water cooler setup. It is stock besides the turbo and clutch. I think he is on 11-12psi. He is running the stock catback and the turbo is recirculated so you cant hear it. I was say it is as quiet as a Prius. We raced last week and he was 1-2 cars behind me. I think I pulled on him as the start and he held it there. He also didnt brake boost.

He could be faster if he ditched the stock carback and got an air to air fmic.

better trans it's hit or miss .. F23s have been pushed up to 500 hp.. suspension ok and the engine for a 06-07 2.4 can be pushed hard as well

lol he needs to get that shit looked at .. at 11-12 psi you should be far behind him man.. shit at 8 psi he should probably be staying with you

11-12 psi on that setup should net close to 300 whp maybe more

unless you have nitrous or something lol

DiabeticKripple 04-01-2011 02:50 AM

my power goals are right under where ill have to build the engine or tranny, so if its at 400, then 350 is my goal. run whatever i can to get that number

DiabeticKripple 04-18-2011 11:13 PM

bumpage.

terry11 04-19-2011 09:05 AM

Your dumb if you think it would only take a grand to build your internals. And an lnf on a good byt tune and e-85 would still probably smoke you, with you on 25 psi if you built your motor. Do some more research imo

you are smoking something good if you think a tc on a stock turbo can beat a turboed le5 on 25 psi ( pending what turbo it is of course)

Sounds like his tune needs to be dialed in. A turbo 2.4 losing to a stage 2 SS/SC should not happen :lol:

if you can afford a SS/TC I don't see why you wouldn't do it but thats a hell of alot more investment than a turbo build on your current car.

Zdeuce4 04-19-2011 10:20 AM

turbo the 2.4... i had one and i loved it

CudaJoe 04-19-2011 10:22 AM

stick with your current car based on your background story. Start with a small turbo build and see how that feels. I can tell you your gonna spend alot of money to get 25psi on that 2.4L... And it sounds like you can afford to not have your car for a day so when shit hits the fan when you try the 25psi thing.... thats not gonna be good.

elecblue06 04-19-2011 10:39 AM

zzp's blocks arent super expensive 4600 or so to have it shipped for a built bottom end that can take 1k engine hp is a pretty awesome ass deal.. make it 6-7k if you want to build the head as well

but even still you could upgrade every part of your 2.4 have larger potential and still spend less than a tc

Haha ok. And i love how ppl with no turbo experience at all come on this forum, read a thread and think they know everything. The 25 psi has absolutely no bearing on this conversation at all because his car will most likely never even see that much boost. I must have missed all the threads on the 2.4's running a train on lnf's. Sorry my bad

dude seriously.. my car is turboed lol and 25 psi on the same turbo ( assuming they're both upgraded ) the 2.4 will make more .. no replacement for displacement man. not to mention the head on the le5 i think flows better then the stock LNF the lnf has the benefit of better efficiency with di but still

there aren't alot of 2.4s that have gone for crazy power most people just turbo it and stay with 8-10 psi .. making under 300 whp. there are some people who have actually done some nice stuff.

most lnfs dont go over full bolt ons either .. shit their are more 2.2's running trains on lnfs then 2.4s and there is only 1 of them running 25 psi lol

i mean figure a byt tune on e85.. 370 wtrq and 340 whp .. on 24 psi.. a turbo 2.4 should be able to make that on a properly sized turbo under 20 psi

DiabeticKripple 04-19-2011 11:33 AM

Zzp has a car (don't know if it is theirs) running their stage 3 turbo kit, 2.4l running mid 11's

Rissa 04-19-2011 11:40 AM

Truth is there aren't many 2.2's or 2.4's "running trains" on lnf's because no one wants to put the $ into them, and it is harder making higher hp numbers reliably.

this.. most people bought the 2.4's or 2.2s to get a cheaper car so they are cheap lol

the 06-07 2.4 can handle power but no one really pushes it

You're right about the displacement on the same turbo and the power levels they make, but just like you said most guys won't ever build the motor. They just swap it and leave it.

This guy obviously has A LOT to learn and I'm not saying thats a bad thing at all everybody has to start somewhere, I was merely saying that I think his best option would be getting an lnf and saving himself hours and hours of headache and trouble.

This is exactly what I was trying to get across

That's a vendor car. Of course it's going to be fast as hell

DiabeticKripple 04-19-2011 12:19 PM

This is exactly what I was looking for. Thanks everyone. I just wanted some criticism and honest opinions on it, I'll just make this car a show car, then buy a rwd, v8 and make that my fast car

Zdeuce4 04-19-2011 12:26 PM

my turbo 2.4 had a little over 300whp.. and i only spent 1300 on the turbo setup.. (bought it off here)

it can be done for a good price.. proper turbo choicing and having reliable shops in the area for help are a plus... trifecta tuning isnt too bad either

DiabeticKripple 04-19-2011 01:55 PM

If I went zzp stage 3 then I would need around 3.5k for it all plus a new catback and clutch

u dont "need" a new catback. but its a plus. elec cutouts are like 150-200.. mandrelexhaustsystems.com makes affordable 3" setups as well
