323 turbo

[ed325i]

I want to do something to my 323 engine so I am thinking of fitting a turbo.
I want to build a manifold like this one.



But what turbo should I use? How much boost can used with the standard pistons / air flow meter and ecu ? I know nothing about turbo's but I want to learn.

B23 lump is LE Jet, no way to remap the ignition Ed.

that is a LHD spec manifold, you could make one similar with a set of flanges and some welding.

As for turbo choice ..... what are you looking to gain from it, more torque, massive HP gain , daily driver or weekend/track toy ??

Stock boost limit for a cat ready B25 is 12 psi , 10 is max safe limit in my experience, unless you can comensate for a charge temp hike come summertime, assuming we get one

Turbo recommendations from experience.....

Daily T3/4 hybrid ( built for the app, no cossie donor Ebay shite from china!! )
Daily with HP bias, H1C, H1E or HX35/ 40 series.
Max HP monster, CR drop and HX40 in 82mm trim comp and 77 on the Turbine.

Ant it's a RHD you can see the steering
I want a fast/daily driver could I use the turbo from a saab or something.

But Ant means, that manifold came off a left hooker. I.E USA m20.

Would this turbo be ok?

LHD spec manifold though dude, well it was prior to the angle grinder

SAAB turbos will be too small, any 4 cyl turbo will be too small and restrictive TBH, the 6 cyl has 2 more pulses per revoloution so a 2 litre 4 pot turbo will be worked 50% harder than in the stock app

I used a cossie 2WD unit, massive torque , superb daily driver but it had too much torque, and not enough HP to be really really rapid. a high A/R hotside would work well enough, but even the T3 biggest (0.63) is still a little under "perfect" I ported the last one ( D1mmy's car) out to almost 0.80 to get the boost where I wanted it

think BIG dude, its the best way

[ed325i]

So something like this ?

No mate, thats waaaaaaay to big for what you're wanting, A/R hotside is too big for defo, the cfm is low too given the claimed spec I'd expect to see 12-1400 cfm

XS Power= Chinese built shite dude, a proper Garret would be £1200 ish for that application, its cheap for a damn good reason, the material spec is not up to the task @ hand.

IMHO of course

Would this work???

[Ant]

that is tiny dude, from a LPT setup, GT series turbo but Uber small trim sizes from that pic.

Something like this maybe ?

More like it, seller need to supply way more info, the A/R is the ratio of inducer to exducer, but without supplying info on the wheel sizes themselves, that info is irelevant.

Big hotside from the look of it, needs ext w/gate too, more space to be taken up, but it can be done.

Interested ? Ask the seller to remove the housings and measure the wheels themselves, Comp wants to be 70mm minimum and similar on hotside (turbine)

I reckon the hot is a 1.08 ish, that info is part of the casting so thats easy for the seller to find.

Isn't that Mop's manifold?

I'm about 99% sure those are my head flanges there anyway and that the mani has been fabbed.

[clubfx2]

Ant, what sort of money would it be to do a turbo conversion???

[Ant]

I'm about 99% sure those are my head flanges there anyway and that the mani has been fabbed.

could be M8, look inspired by the stock LHD items with an adapter though for defo, nothing wrong with that either

Clyde, what you got in mind ?, best to PM as I cant "trade" on the zone.

[Turbo-Brown]

Just had a look at Mop's thread on e30tech, defo a scratch build

[Emotechnik]

Getting a lot of interest in this, if your interested then make me a good offer, don't need messing around.

[gcorky]

name a price matey !

Erel you will be limited to internally gated turbos with the bbr cast mani,
but i have seen adapter flanges but bonnet clearamce may be an issue....what turbo are you gonna go for?

[blingsta]

still not 100% sure Graham.. 90% getting a new garrett so just a straight forward swop jobby.. other 10% says get my one refurbed,
