Hey guys, to make a long story short, i have a 97 civic turbo. I need a turbo. I test drove a 335 today for the first time, and then immediately after drove an Evo IX.

In short, the EVO IX had the exhilarating feel i was looking for, while the 335 was still fast, it just didn't feel like a rocket like the EVO IX.

With that said, the 335 is WAY more my style from a looks and whole image perspective, but the EVO IX had the EXACT performance I was looking for (tight seats, super sticky handling, and rocket ship style acceleration)

I really hate to ask something like this, but does a 335 with some raised boost feel anything like an EVO IX in terms of acceleration and speed?

And finally, I know the turbos are small, so is there usually a PSI level that the stock turbos can handle? Likewise for the engine...

Thanks so much and sorry for the blatently NOOB questions.

with a tune the 335 is a different beast.... But of course having supporting mods will help like a upgraded fmic , Catless dps , intake , charge pipe with bov , and meth then your 335i will be A new different type of beast

I have a Cobb stage one aggressive tune with a agency power fmic, er charge pipe with hks bov, and a ac shnitzer export dual axle back exhaust and man do I love being in boost lol

I believe staying under 16 lbs of boost will cause no problems but I dont know...

Depends. You plan on modding it? With the mods he mentioned you are looking at M3 like straight line power. With a bone stock 335i you can get a proceed/jb/cobb tune and it will take the stock ~8psi up a decent amount. I know when I bought the jb+ it added about ~4.5 psi to the stock 8 psi and made a very noticeable difference.

N54 or N55?

N54 ~19psi with supporting mods, 12psi tune only, 8psi stock.

There are forums for both engines under

http://www.e90post.com/forums/forumdisplay.php?f=378

Check out the N54 Engine section....you will see tons of information on there regarding tuning, 60-130 times, drag times, and mroe. OEM turbos can handle up to 18 psi with supporting mods, going over that is probably not going in increase any performance. A full FBO car with meth can see 440 hp at the weels, upgraded turbos ~500 hp, and Vishnu/FTEC's big single @ 644 rwhp.

I daily drove my Rob Beck turbos at 19.5 psi safely, no AT issues either.

[J3NGOe90]

14.5psi i would say

We've tuned many 10s eves and now a few 10s n54s. With a single turbo, the n54 feels every bit as quick/powerful as an equivalently powerful Evo. The difference is that it is far more drivable and less laggy since it's a high compression 3L vs. a low compression 2L. Tuned properly, with an appropriately sized turbo (so that it's not choked with exhaust back pressure), and sufficient octane, we have yet to find the boost/power limits of the N54. So far, we've been running up to 25psi with power in the ~680-700whp.

As always, hardware and software configuration/tune is key. Trying to run the factory turbos at 20psi will cause a lot more thermal stress to the engine than running a big single at 25psi with supporting mods.

Its been said here a bunch already. Basically a stock N54 runs its turbos at ~8 psi & dynos @ 270 WHP/280 WTQ. On a FBO (Tune, Intake, FMIC, DPs, upgraded CP + DVs or BOVs to withstand increased boost) N54, the turbos are good for 18 psi & 370 WHP/410 WTQ. With meth, you'll be over 400 WHP easily.

If you really get that power hungry, you can always upgrade to RB Twin Turbos or the Vishnu/HPF single-turbo kit.

[zerep1]

Boost is boost this engine has shown to handle 500whp reliably Shiv would say 700whp but like they said tune it and I feel like it will never feel the same unless you turn it into a race car example my car has 80whp over stock and 100wtq over stock and still feels like it was meant to have that power even though I would easily pull on stock evos

The Evo IX is a laggy car compared to an N54 twin turbo equipped car, therefore when the boost 'hits' on the Evo, its going to feel like you are going like a bat out of hell. It is never going to feel like an Evo IX in terms of acceleration unless you get some aftermarket twin setup or a single turbo setup. I don't care what anyone on this forum says, but the stock twin turbo setup on the N54 doesn't feel like a turbo car whatsoever, it feels like a small powered V8 under the hood (smooth and linear). You can still make decent power on the stock twins with the supporting mods and make over 400whp, however they are apples and oranges when it comes to their powerbands and feel of acceleration.

Last time I checked a 10 second car was a car that ran a 1/4 mile in 10 seconds, not a car that can theoretically run a 1/4 mile in 10 seconds.

Last time I checked you made a post every single time a single turbo car went to the drag strip.

Apparently, LOTS

I want to mod it, but no heavily. I figured an ECU flash to raise the boost was all i would do.

If i spend 25-30k for the car, there's not a whole lot more money i'd like to dump into it

This is what i realized today. I no turbo lag is not desireable. But i felt like the BMW was too refined for me. And it's a shame because i love the looks and the specs.

The thing that really drew me to the EVO IX was the handling (felt like it was on rails), the acceleration (rocket ship), and the seat (held me in it like a rock with no room to move side to side).

It sucks, b/c the things i really liked about the EVO IX are things that the BMW didn't have. And the whole reason i wanted the 335 was to break away from the stupid "Ricer" image. But i'm all about raw performance, and the EVO IX felt like it would run laps around the 335. I know thats not true, but it's just felt more exciting than the 335.

[dj_335i]

I have both cars. Fully built evo, have had two now and a 335 with bolt ons that I daily drive. I believe you can't really compare the two cars. They are not in the same class. I'm not sure what you plan to do if you mod the evo if you get it but you can run up a big bill quickly. It cost money to go fast so mod wisely. I will also driving the evo, I get too much negative attention now while I don't get any negative attention driving the 335.

Here is what psi is safe for the turbos:

The car is going to be for fun and the occasional road trip.

I much rather be seen in the 335, but much rather drive the EVO ...

FUCK!

[bigdnno98]

I battle the evo urge sometimes too. I love my 335i and it is pretty damn fast. I watched an evo 9 trap 111mph in the 1/8 mile though while I was trapping 90 and I was like "holy shit that thing is crazy fast!". They are super fun to drive but I'm not sure I'm ready to give up my BMW for a Mitsubishi. I"ll prob stay BMW and make it as fast as I can afford haha

[Ace_HollyWood]

You sure check a lot of stuff.

yea ... i think what i liked most about the EVO was the acceleration. I didn't feel it as much in the beemer.

I see you have a 407whp 335, is the power curve still linear? or does it get into rocketship mode like the EVO?

Second, the EVO's seats were perfect. Bolsters held me tight, and I couldn't move side to side. Can the BMW achieve the same result with their seats?

[Ace_HollyWood]

lux an sport package Bolsters are adjustable!

Just how adjustable though?

Could i make them so tight that i can't sway left to right if i try to?

[TOS_335i]

That tight... I'm 6'2" 175 and they are tight...
