NA tuning combo

Hi guys, has anyone done a NA tuning combination like the following?

-Drop in K&N Filter
-Bespoke Remap
-Decat Exhaust system
-Gas Flowed Head
-Port Polish
-Knife edge crank
-Crankshaft balance
-3 angle valve
-Colombo & bariani Fast road cams
-Skim Heads

If you had these mods or similar or maybe advise even i would appreciate it a lot guys.

I planning on doing these mods to my 3.2 Brera, dont worry im no time waster or big talker, i have actually already removed my engine so its on! haha i just wonder what performance increase i can expect really....

Thanks guys!

I'm not a petrolhead, but nice wishlist. Although a bit pricey. Have you checked prices of the cams and custom exhaust at least?

Ok, keep going, you have a fan. If 2litre JTS can make 300HP (still NA), I'm pretty sure 3.2 can go skyhigh as well, despite of older tech.

Why bother for 10kw, I know the 3.2 jts has been supercharged successfully but if u want to stay na it's gonna cost a fortune, dawies will prob help you with that maybe with a big bore conversion or turbonutters will prob turbo charge it for you which would be my favourite choice, otherwise keep it simple.

Would you really pay half the brera price (think I'm not too far from the wishlist total price) for additional 10kW only? That 2litre example was a racing setup rather (like this one here - Alfa Romeo 156 Super 2000). But with a properly done headwork, wild cams, custom exhaust (not decat only) and remap, 300HP is minimaly a MUST on stock 260HP engine imho.

I think 300HP is a feasible number for the brera/159 3.2 litre with all the mods you are thinking about. You should keep in mind that when buying the Colombos you should ask as well the timing tool needed in order to have them correctly fitted. Also you could raise compression ratio a bit once you are going to have a "head job" done by shaving off a bit of your heads (about 0.3mm - 0.5mm if applicable). Good luck with your project and keep us informed.

I did some NA tuning to 3.0 busso engine (well it's all the same principle)

With your wishlist you should be in the 300bhp region. I came from 220bhp to around 270bhp on a check engine light (no maf and no remap so runing in limp mode)
I have AHM regrinded cams, catless manifolds + homemade freeflowing exhaust, 0,8mm skimmed heads (11:1CR), slightly ported heads, lightened flywheel and custom made intake plenum (bigger and trumpets inside + 82 mm throttlebody)
Still have plans for fully balanced engine and a decent remap with higher limiter (should be close to 290bhp i hope)

It's not cheap, but hearing the v6 NA engine scream it's all worth it

I recommend you to lighten the car too if you can, it's the biggest advantage in acceleration and driving dynamics.

oh yes i totally agree weight reduction is what i really need but i cant really see anything make a real difference to the cars weight other than ultra expensive O.Z wheels, ok and apparently the exhaust system is also quite heavy so ill save some there

Find some second hand o.z. wheels and it will be much cheaper (-15kg) . Remove spare tyre and use repair kit (if not already fitted -15kg) Maybe some two piece brake discs (-5kg), like you said the exhaust (-10 to 20kg) And ofcourse engine tuning means lighter things to, lightened and balanced crank + pulley + flywheel (-5kg)

I think around 50kg less is possible withouth any drastic procedures

Yeah, unfortunately Turbo is the way forward. But there is no replacement for displacement

Ok the Brera's engine is already out, now you've got my attention!

Iv always asked why guys would insist on a 3,7/8 and not just go 3,5 surely its cheaper and will also give an improvement in power?

Remove the propshaft!!!

wow now lance haha im not going to increase displacement, thats too much of a mission already in my eyes.

as for the 4wd, yeah i also looked at ways of making it 2wd but it seems like a hopeless cause, its a very complicated system this......

No, its pretty easy!
Change the gearbox to a f4 gm v6 one, remove al 4x4 stuff and replace the rear wheel hubs (bearings) by closed (4x2) ones.

Not sure if there is a Alfa 4x2 3.2 gearbox

Hahaha, ja Engelse forums zijn wat verder op het diesel front.

There's a 159 3.2 4x2, so you could use that gearbox.
Rear bearing don't have to be replaced, rear cross section does.

thanx allerd but that already sounds to me like a big mission. and the 2wd 159 3.2's just started coming out in SA so finding that box is close to impossible.

on a side note i can actually understand what your saying in dutch more or less because i speak afrikaans actually, hehe interesting on how borderline close languages are.
