anyone ever turbo a 348

Nizpro in Australia did / does a twin turbo kit for a 355. probably adaptalbe for a 348 I would think.

 

Looks like plenty of room to me. I've built many twin turbo systems with much much less room than this car has.

IMO building the turbo system is the easy part. Problem is tuning the stock ecu(s). Yes you can go aftermarket engine management but you will no longer pass obd2 plug in test on 96+cars.

 

I dont think that there is enough room. Where do you put the parts? And wich parts and dimensions you choose? My engine compartment is completely full. I didn't get the right dimensioned airfilter in so i had to choose a smaller one wich isn't good for the performance i like to get. But theres no way to put more in. Ok für a small turbo setup with small turbos it would run out right ok then the turbos fit right beside the engine block between block and wheels. But on bigger turbochargers like GT3076R or GT3582R you have to put them over the gearbox. The 100mm Exhaust pipe over the gearbox in the middle to the exhaust. Then you got a problem to fit a good size water cooled intercooler somewhere in it. And the airfiltering issue. The turbocharger inlets facing the suspension. And the intercooler pipes from turbo to intercooler wich maybe fits over the exhaust will get a problem to route back into the plenum chambers because the turbos are in the way. So it gets a ball of pipes and hoses. Or it will get a bad setup like putting the turbos over the exhaust 5 meters away from the cylinder heads and put a too small intercooler maybe even only air cooled where the filterbox was and thats it but that isn't a good conversion and will not achive big HP levels .. or don't hold them long on the Autobahn or Circuit.

 

Well you are entitled to your opinion but I build turbo systems and tune cars for a living and can tell you the 348/355 engine bay poses no problem at all in terms of space. None at all.

Obviously when you build a turbo system you do not just do it around all of the original components.

A simple explanation is turbos could be placed where the stock airboxes are and fed by the primary side of the stock headers. Airboxes fabricated into area behind rear wheel. Liquid/air intercoolers between turbos and intake plenums. Remove bypass valve from Y-pipe and install wastegate. Fabricate new exhaust system which accepts turbo downpipes and single wastegate tube.

 

I do that for living too and did that also to the 348/355 already. And ofcorse none of the stock components remain. Only the head + block + drysump remains internals and externals swapped.

If you say the intercooler between the plenum and the turbos it is what i mentioned then the turbocharger is to far away from the cylinderhead or how do you mean it?

But like i said it is possible but for me the room or better to say the usable room is not good on the 348/355 compartmend to align all components properly.

 

So you are first saying there is not enough room to fit everything, then you say you've done it, then you say you can't align all the components properly.

I guess I don't understand what you're really trying to say as you're contradicting yourself.

All I am saying is that I am confident I could build a twin turbo system for this car with excellent fitment and symmetry as I've done so with far less space. I build or modify every component necessary, I don't just take intercoolers off the shelf, I take cores and build the unit to fit the car.

If you do not believe it is possible than I would rather agree to disagree than try to convince you otherwise.

 

There is room to twin turbo a 348.

The Aussie 355 had twin turbos and I am sure the 348 has just a little more room in the engine bay than a 355.

 

i didnt know about the 355 with twin turbos
in aust

 

Yeah, it's called a 355 Ahahahahahahahaha!

Just so you know, I owned a 348 before my 308QV and loved it, so no flames please...

for the money to twin turbo a 348
you might as well leave the ferrari as is
and buy a Lotus Esprit twin turbo for heaps less than u would spend putting the twin turbos on an already perfect 348

 

Here ya go my friend. The Aussie TT 355 Spider!

Prepare to blow in your pants!

top thread
yep i blew big time
that is totally sick brother
wat a beast

 

Its an awesome car mate!!

 

thanks for the info paps
ill be reading that thread all night
very interesting
that 355 is a monster

 

Read away my friend.

Its a shame all the first pics in that thread are "lost".

Still, some great pics and a good read in there. Watch that Youtube vid, its a VERY VERY fast car!!!

Not my car. No need to comment about the styling of this "bastard", i think we all agree..

Wiseco low comp pistons (9,0:1) Two MHI 18T turbos, Electromotive Tec3r management. Claims 600 BHP.

No reference about long term durability as the car is a track toy and has no Norwegian plates...

 

The Koenig F48 was turbocharged.
550hp compression ratio of 7.8:1

feel sorry for the clutch though

 

and a Testarossa V12 in a 355 !!!!!!

far out
wat a beast

 

Thats the one mate.

VERY fast!

I feel sorry for the entire drivetrain.

Sounds great.

 

Looks like the guy could use his tires as his clutch

So why hasn't anyone tried/done this yet? I would think 420hp is easy with low boost. I'll volunteer my car Already has better brakes and weight removed.

 

The shop I go to is building this beast.
and it runs a LM 355 transmission.
