Hey guys.
Can the C16XE engine take a T3/T4 Hybrid turbo WITHOUT having to strip the aircon? I have heard I will get a T2.5 in the bay and get to keep the aircon, but there's no chance for fitting a T3/T4 as there's no room except for throwing out the aircon! Aircon came standard and I don't want to lose that luxury! If guys can fit a 2L 16V lump with TBs in a Corsa engine bay then surely there must be a way to do this?

t3 is too big for your motor
use the t2 with a high trim compressor.
big boost will not be sustainable without total overhaul and upgrading of most internals including pistons lubrication system con rods crank and bearings.
the compression ratio needs reduced from 11.0:1 to about 8.8:1 for a good 15psi kit

Yes it gets a tad hot in SA. I highly reccomend that major engine uprating is essential with ANY turbo work with the 16v 1.4/1.6 engines. You will need everything that agent blue mentioned, and then some! Prepare for unreliability though, but if you manage to pull it off without going bang within a month, then well done!

Haha, what most people don't realise is that a T3 sized turbo is really big, its a hell of alot bigger than a T2 or T25. The T4 is bigger still.
A T2 would start to spin up at 2500Rpm and at 3000Rpm it would be spinning at full boost. A T3 would start to spin at 3000Rpm and hit full boost at 5000Rpm where it would tear your engine into pieces. A T4 probably wouldn't even totaly spin up apart from maybe in 5th gear where again it melt the engine into a metalic football.

Any1 know what size turbo is going on the new GSI?
What size do courtenay use too?
Thinking about doing my 1.6 with aircon!
But not by courtenay though!
Dont like the idea of 3 head gaskets!

You've got it wrong about the T3.
If its fitted to the crappy 8v RST engine then there is no way it will damage a c16xe (if compression lowered properly). If you want a cheap readily avaliable turbo for a c16xe then I would have thought the T3 is perfect.
If anything less that a T3 is fitted then there's not much scope for big power.

Its actually a lot simpler with tb's than without.

RS turbos aren't T3, heh, RS turbos are T25 - 140Bhp or somethin. T3's flow like 190Bhp+
T2's and T25's are tiny, they're the turbos that come as standard on almost ever turbo charged car (even Impreza's and Evo's), T3's are alot bigger and come on very few cars, one I can think of is the Lancia Delta Integrale EVO II 16v

throttle bodies every time for me, much more reliable and cheaper, and they sound the bollocks

Hey guys!
I am doing the following:
Fitting a stand alone management system.
Completely different exhaust system. Custom built stainless steel 63mm free flow system.
Astra GSi front and rear discs conversion.
Stripping down the whole motor for complete overhaul:
Dropping compression, getting stronger pistons and conrods, balancing crank,gasflowing head, etc.
I reckon the motor should handle this on 0.5 to 0.7 bar boost on normal days and at the track I can boost it up to 1.2 bar with higher octane fuel.
Just wanted to know if anyone's fitted such a big turbo in a Corsa's engine bay with the aircon still fitted! Heard you can only fit a T2.5 as it's the only turbo that JUST fits! The T3/T4 housing is too big!

Escort RST's use T3's. Fiesta RST's, R5GTT use T2's. You get different versions of T2's/T3's etc for different outputs.

the garrett range has changed now and the turbos you should be looking at are
GT12, GT17 and the GT25

Yeah the RST used a T3. Strange really if you compare size of other turbo engines as the .8 200SX S13 used a T25 and the 2.0 S14 a T28. The Fiesta RST as mentioned used the small T2 as did the Silvia 1.8 T.
The T2 is not the best Turbo, its has heat problems and doesn't flow so well, hybrid versions with different cold wheels etc were on the market.
As for a T3 ripping engines to bits
the MG METRO TURBO had a T3, and if you don't believe me check. This was a 1274 a series engines, making a smallish 93 bhp too. They always used lowish boost (about 5-6psi maybe) as any more made the gearbox stress out.
As for different types, the T3 on the MG METRO TURBO , was exactly the same as the LOTUS ESPRIT TURBO of the same time period. MAD.
So there you go,

If your stripping the engine down then I'd recommend you go for a new inlet manifold as it will make the turbo conversion so much easier + give more power. The standard inlet pipe work is all round the back of the engine but with the new manifold its straight off the manifold, see pic below.
If your going for uprated internals then I can't see a problem with a T3, if it was me I'd go for new inlet manifold, T2 or 25, lower the compression slightly with a thicker head gasket and run about half a bar of boost.
Wouldn't give massive power but should be a nice increase.

I'd never run a 1.6 with a t2. No point running a t2 at 7psi, you would probably make more power with just the inlet manifold n/a.

I'd never run a C16XE witha turbo anyway. Sounds good, looks good, but never gonna be as good as throttle bodies (well, apart form the extra torque u'd get)

Depends how well the job is done.
With unlimited money, the turbo'd engine would devestate a tb'd one.

Yeah, look at the power people get out of R5GTT's, and they are really poorly designed engines.
