So lets get to business...

I am purchasing a water locked 335 motor and im gonna build the hell outta it and drop it in my car.

I wanna stay twin turbo'd with low lag, tiny turbos but maybe a little bigger then stock.

I dont really want jap turbos, but I know jack about brands of turbos.

What turbos would yall go with? Any other cars you have driven have small turbos that are amazing?

Please, school me on what turbos are the best, im going to aim for ~25-30psi, twin turbo'd ofcourse.

The only turbo experience that I have aside from my 335 has been with Garrett turbos. I ran a GT30R on my s2k and I LOVED that turbo for that car. All of my friends with various cars (several high HP GTI's, Evo's, turbo s2k's) all ran Garrett GT series turbos without any problems. Even when they ran GT35R's or GT40's on a small 2 liter engine, they would spool up pretty quickly. They are water/oil cooled ball-bearing turbos that have a pretty good reputation, and they make different sized turbos just for about every application. Now the question that comes into play is how much room is there in the engine bay, and how big can you actually go if you stay with twins? Twin GT28R's sound nice, but would they fit? Also, larger turbos mean larger wastegates that require more room. Maybe converting to a larger single turbo would be better since it should still spool quickly with the relatively high compression and the decent sized displacement of the N54. Another thing is that you will need new manifolds since the stock ones are a one piece design with the turbine. Also, once you have the new turbo(s) to provide you with the boost you want, what will you do to supply them with more fuel? Its not like you can pull some RC injectors off the shelf. Seems like there will be a lot of work ahead of you, but whatever route you decide to go I wish you the best of luck with building up that beast! Keep us posted.

FYI, the stock turbo's are manufactured by Mitsubishi.

I know, Garret is high on my list, thanks for the review. For fuel, aux pump or two pumps, we will see.

[Walked U]

Gt28's.

If you dont want japanese turbos run dual k24's. If it wont fit... make it fit.

If your buying the block just relocated everything to make the turbos fit properly.

Btw. k24s are what upgraded 996tts run.

Or you can go k24 hybrid like the 996tt promotive car and build the block and do some R&D into injectors.

That should give you 800+ rwhp.

Make sure you find a good tunner also.

Good luck tho man im rooting for you. Its a real pain in the ass to do a custom build and R&D everything yourself.

Its a pain in the ass to R&D an already built turbo upgrade lol

[335iheLLraiseR]

out of curiosity...where did you get the engine? it wasn't that $9k on ebay was it?

[E90Russ]

If you move to bigger turbos you're going to get more lag (likely noticeable), no way to get around it.

[schneid4323]

I dont wanan run HUGE turbos, im gonna run small turbos, maybe the K24's, obviously the headers would be custom and we could make everything fit, ofcourse the tranny will be swapped and all other sorts of things, the goal is to make ridiculous HP, and keep the engine bay looking relatively stock but ofcourse not completely, already have intake intercooler and methanol, the intercooler is good up to 700 hp, so stage 2 would be developed . No i didnt find the engine on ebay, I found it at the dealership that im well respected and liked at, ill pay maybe 2.5k for the motor, and maybe 10k on parts, then sell my motor.

its wierd, they say the company that makes them is mitsubishi heavy industries, but they are really european made turbos, made by Mitsubishi Equipment Europe or MEE, which its headquarters and compund/facilities are in the netherlands, which and where they produce the twin scroll and variable vane turbo chargers.


btw i wish u good luck, it will be interesting, i vote for garret aswell, nothing but good things about them and a wide choice.

...yeah, and the Garrett turbos might even be made in Japan... or perhaps China by now...

how much is the motor going to cost you? after your done build your old one and sell it to someone

more importantly what was the damage and HOW did that engine end up like that O_o

serisouly you have to be an idiot to do that (not you the owenr)

It was hydrolocked in 3 feet of water, a few bent rods, turbos were flooded car was flooded. Motor ~2g

[533ogetnom]

but.. why

was the owner RETARDED?

I think there'd be a lot of tuners waiting to see what you come up with as far as the injectors. Haven't seen one solution yet. So let us know!!

[Driver72]

I'm not turbo expert but to get 25-30 psi, you are going to need turbos that are a little bit bigger than "a little bigger than stock".
I think our stock turbos are good for 16-16.5 psi.
A little bigger turbos would probably get you 20-22 psi

Good luck with your project, and BTW, I'd suggest getting a vented hood then too. This engine already makes enough heat and could use the M3's vented hood to release more heat. You'll want to do that with the bigger turbos for sure.

Keep us posted with progress.
Good for you.

[Driver72]

BTW, what tranny are you planning on dropping into that car?

I forgot about the over heating problem - esp with increased pressure. You're going to need one hell of a cooling solution - not just upgraded oil cooler and intercooler - due to insufficient water flow around the engine block. If upgraded water pump does it - that sounds like the least costly route.

[PshhhhhMW]

*subscribes to thread* good luck bro!

[schneid4323]

There are going to be alot of things that need to be changed heating wise to make this work, such as oilcooler which is ready to be done on the car. Tranny, well we will see when it comes to that, building a motor takes quite some time. The driver drove the car into 3 feet of water somehow. Two decently sized turbos will make a decent amount of boost, our small turbos with some cut fins on the hot side make 15 psi constant without issues. Frankenstein is gonna be rebuilt again

What size are you installing?
