what is the pattern for the gearbox housing, does a F23 bolt on? the 90 mm bore and 78 mm stroke is quite interesting for some high rpm plus a holset hx40

It should be GM, a few people have attached the 2.3 version to an Omega box for RWD cars.

depending on the back to front layout and packaging , it should make for a very capable 600+ hybrid griffin map the Trionic yourself directly with this: http://trionic.mobixs.eu/

"chip" from vauxsport.com Nova C20let to B204

looks like a ttv flywheel , and a GM pattern housing

ohhh yeah, I remember hes doing that swap now after cracking his LET block with uber boosts Check his charge cooler out.... 17Litres capacity

[siztenboots]

check out this baby Holset HX40 on the left , GT3076 right

LOL that looks familiar

Does he say what the nomenclature is? HX40 is just the bearing housing size.

*Looks like a C86*** impeller at a guess

The problem is you just put high RPM and F23 in the same post... and unfortunately the F23 is really poor for high rpm applications

is that because of the syncro's?

No just because the gear ratios sucks and even if you fit the extra short 4.41 FD, the ratio themselves still suck...

i agree, just changing the gearing is waste of time, I might as well just bolt on 15" wheels.

Difference between Trionic 5 and 7 is mainly the MAF which the T5s don´t have and the B2x5-engines are of a "low friction" type, ie other pistons and cylinder walls (pistons typically less sturdy due to thinner material).
T25 and GT17 are Garrett turbos, TD04 Mitsubishi.
The B204E lacks the Magnetic Valve that controls boost, it runs on base boost only.
Difference between B204L and R are WG actuator, IC and ECU.
From this you can learn: the first 2 digits denote deplacement in litres 2.0 or 2.3, the last digit stands for engine family 4 being trionic 5 and 5 being trionic 7

I thought the T7 switched to FBW throttle?

yes T7 means AMM and FBW and black direct ignition cassette

Heads (info taken from UKSaabs) T7 The only two versions of the T7 head involve the exhaust valves AFAIK: one version (the low power version) has plain stainless exhaust valves, and the other version (high output) has Nimonic 80A superalloy exhaust valves. In later years, the low-power head also got the Nimonic valves, but there are still two part numbers because of the earlier, outdated, head. There are also two inlet manifolds- one for the B235R, one for the other engines. The B235R's intake manifold appears larger, and lacks the strainer (which restricts flow) on the other models beneath the throttle body. The T5 throttle-body appears to mount to the B235R T7 intake manifold, as Vigge has actually done this. However, the T5 throttle body requires a T5 delivery pipe and transition casting to match. The T7 head has lighter valve-springs because it has lighter valves: the stems are thinner. (about 5mm diameter) That means the valve guide openings are also smaller, etc. Thinner valve-stems = more gas flow and less need for tight springs.

looking at engine mount positions, it has a sort of swing arm torque damper and a similar back under gearbox central mount
