vectra a, turbo c20xe

[fire]

Hi,
my car first was vectra 1.8i(90ps), then i put 2.0i(115) and put SA ecu vems(controling

petrol and lpg). Stock engine, but compression was 11:1.
One acceleration run:
YouTube - Vectra A vems 402m
Now i put c20xe 2.0 stock with z20let head gasket and oil nozzle for pistons cooling, remove

maf(becouse vems), sfi box, ported thortlle, 60mm exhaust pipe, siemens 890cc injectors and 4 audi cops.

On lpg cars had:


But i converted to e85 and dyno:



Now i'm putting turbo(t3 trim 60, 0.64A/R), soon it will be done.







I'm hopping to get 350Nm and 350Hp with stock pistons on e85.

Little update after 20 000km with turbo:
engine bay:

turbo(t3 trim 60, 0.64) and external wastegate

IC (600x190x80mm)

Exhaust 70mm without cat


So far i'm at 0.3bar boost from 2600-6400rpm, then i rise boost to 0.4bar at 7000rpm. With that i have 240-250HP and 300Nm, what is limit for LPG injectors. So far i didn't have time to tune car for e85(900cc injectors) because i need to tune 20+ cars for drag race and hill climb. But now all races are done, so i have time for my car

But i have big problems with gearbox. So far i destroy one f25 and imho i'll destroy new f25 soon . Now i'm looking for f23wr from vectra B 2.0 d(t)i which has same holders like f25. Or do you have something better proposal for me(f28 isn't a option)?

Nice work , mabye you could some f35 or something else from SAAB ? Atleast some SAAB engines have GM bolt pattern on bellhousing

imho f23wr and f35 has the same differential and differential is the weakest spot on gearbox. I'm not sure if i can put f35 without many modification.

So stock N/A engine is good for 300HP with good mapping.

you need to map your stock ecu or buy SA.
