first of all, i am just a civilian. not here to start any war, not here to spam, and not here to advertise (for any sort of forum).

just wanted to share this - i guess you can say, "world's first" 335 with a turbo upgrade (besides the rdsport car [if any?] at least).

mods: if there is any problem please fix it thanks.

Well I must admit, from start to finish, this was a very interesting project to get everything together and readied for NOPI here in South Florida.

From beginning with that huge XS Engineering FMIC, custom fiberglassing it to the stock E90 bumper, and custom fitting the charge pipes around the carbon fiber splitters on the bumper, that project seemed to be the easiest.

Next on the list was moving the coolant resovoir from the left side of the engine bay to the right side in order to give us access to the stock turbos and to supply room for the big snail to be mounted in that empty space.

The turbos were a bit difficult to get off the car and out of the car, but we managed and made it happen. We began fabricating the exhaust manifold once we got the turbo in and the intake manifold we are waiting on a custom built unit from a reputable manifold shop. They are always backed up because they do Nascar manifolds.

We knew we'd be able to get the car from point A to point B on the stock intake manifold, so we weren't too worried about not having the custom manifold just yet. With any sort of boost from this turbo, that manifold will just blow up.

We fabricated the downpipe which we thermal wrapped and added O2 bungs for use of the O2 sensors and the wide band system. The downpipe comes straight off the turbo and straight down, no twists or bends of any sort.

We didn't have the time to tune the car before the show, and also because we haven't decided which tuning system to use. It will either go to Motech or EMS. This week the car will be tuned and the DI system will be upgraded to accomodate the tuning we will be doing. Once we become familiar with the new management system, my car will be getting that same unit as it offers more control of the N54 and thus will allow us to tap into areas the current Chip Torque or even Haltech can't do.

The car made a 50 mile trip to NOPI, there and back. It cruised at 70 mph the entire time, however, it was under absolutely no boost whatsoever. The car wasn't a huge fan of the new snail, but tuning will ease our woes.

It's hard to say exactly what the car will put down with the new wheel, but we feel that with what it did on stock turbos (400 whp pump gas) at 14-15 PSI, it can make mid 500's WHP on pump gas at max 20 PSI, if we decide to boost that much.

We have had the car make over 500 on nitrous, so internals aren't the biggest concern on a system like this. However, it's R&D and we could have a blown N54 any time of the process so you never know.

The car has a great possibility of putting 10's down with the tranny work it has and this setup, on race gas. Once we have it tuned the way we want it, I will put the dynos up. Should be impressive. If anybody has any questions, please feel free to ask. However, I must add that there are some things I was instructed not to disclose so I might not be able to address a few things.

Without further ado, I present the pictures I have gathered throughout the process. Keep in mind, these pictures are of the whole process so some might seem a bit redundant since they've been posted before.

Turbos come off.



The new kid on the block and the reject.













At NOPI.

Your car?

The top mound looks really nice, except there's a little clearance for the intake and the turbo itself. I wish the engine was mounted like a supra or skyline so there's more room to work with.

Which turbo is that? It seems like a precision unit with s cover, but I may be wrong.

[bdkevoIX]

nvm, I found out it was precision pt67 aka 37r.
But I doubt their speculation on 600whp on straight pump though.
pump + meth is a different story.

[FirstClass]

If you want something with huge HP and huge turbo lag why not just save yourself some money and gain some speed and use an Evo? The N54 is great because it doesn't lag while still putting down good numbers, why ruin that?

[Jesal@Project 808]

BOOM!!

Should be interesting to see how this develops!

[BMW///Motorsport]

That thing could be a BEAST! But now you will feel that turbo type performance (turbo lag) that BMW avoided...

I would want a TT setup with one small turbo and one larger one, with th smaller one always spinning, like stock only bigger..

i guess they want to show what the n54 is capable of? regardless of whether it feeds off of tt's or single.
props to VIP, waiting to see what it's capable of when they get their ecu tuning straight.

Theres always those out there that want more power. Doesnt matter what car it is. Hell, look at the 996 Turbo, sure its fast but people are always wanting more.

[SPDFAN]

That's exactly what I'd been thinking about upgrading the turbo on my 335i, but seems like it's a prototype kit. The turbo itself sits too close to the engine cover, it might catch fire down the road even with all the turbine wrap and heat rejecting material. The intake manifold seems like a nice piece, and the way they do it reminds me the Supra.

[Sleepr335]

Awsome

That would be a sequential twin turbo system like that of the RX-7. System is very complicated but does do a nice job when it works.

Doesn't the 335d run that? I thought I read that its been having all sorts of problems.

[Vince@ V K Motorwerks]

damn, let the upgrading begin! I cant wait to upgrade my turbos.

[ZJP]

Very cool to finally see some turbo upgrades, but a huge single like that is going to cause major lag.

I'm still waiting to see a Biturbo GT28RS setup and then I will be impressed.

[retrodrive]

Well, I am not one to buy something of this magnitude from a random new company; however, I give props to VIP Tuning for pushing the envelope. I am very curious to see how N54 holds up to all this power.

I am looking forward to Greddy kit or even better HKS setup for our car.

Funny how everybody was hating on VIP a minute ago and now everybody thinks that they are cool.as "hotrod" would say, it is yet another schizophrenic change of mood on this board.

i never hated them nor liked them.... just wanted to share what they did and how cool it is to see that someone finally took a risk

[bdkevoIX]

37r is not huge by any means.

Hell, alot of evo guys use it on their car and that's on 2.0L mostly.

On a 3.0L it should spool up fairly quickly. Once it spools, Watch out!

It should feel like a single turbo supra.

Twin gt28rs would be interesting though.

[Icyhot85]

how far away are we from vids/dynos?

I wasnt talking about you but A LOT people did. Thanks for posting. Looks very refreshing from your old boring "I got CEL from Procede" and "is a winner" posts

[ZJP]

I wonder why they used an E90 rather than an E92...

[SoFlo335]

I really dont think they care about having turbo lag. If they did, they wouldve gone a different route. I think they are going for extreme power, and plus when you have 500whp, I dont think you will be worrying too much about lag. Also, its not like you wont be making any power during lag, you still make a good amount of power, and specially when you are making 500whp at full boost. Props to VIP, nice work guys!
