i have a x14xe that i'm wanting to fit a larger throttle body with some saab blue injectorsor similar, with a power boost valve.
basically i want to know what other vauxhall models i could get the t.b off at the local scrappys, that will be a straight replacement for my standard one without loads of hassle.
will one off a astra 1800 or 2litre go staight on?
my intention is to run it with a lexamaul or mantzel inlet manifold, 4 branch exhaust manifold & a mappable chip.
any comments or help appeciated

Possibly mod a nova GSI/GTE throttle body, but you will need a mantzel power box to do it properly, wont need bigger injectors till ya running throttle bodies and thats when ya running major rpm and wild cams

on a standard lump the throttle body isn't really a limiting factor

ok, i was just thinking along the lines of if i'm getting more air in with a larger t.b, i would add a bit more fuel. do you think the boost valve will keep enough pressure & fuel in?
has anyone else got this sort of package?
what sort of bhp do ya think it could achieve?
its all for a 1995 corsa.

dont get a boost valve, get the car mapped properly.
a 1.4 16v with inlet mods...about 110bhp tops.

i almost bought an x14xe with a boost valve and full sebring zorst, which stangely ran 106 bhp  the throttle body may improve throttle response a bit and induction noise but not give any extra ponies as such

A nova GTE item goes straight on, but there's no ICV, fitting bigger injectors is just asking to run rich and loose power.
Get the inlet modded and unichiped.
As said a powerboost valve does pish all, it's just a fuel pressure regulator.
best get saving for a mantzel I guess

could you attach a ICV to the plug on the loom but fix the ICV out the way and not have a fault code pop, how is idle controlled on the GTE cos surely the X16XE wont idle without a bypass round the butterfly

They had a seperate ICV, yes it will idle.
It will idle fine without it, but when cold it won't idle so happily, that's all.

so to summerise some opinions so far:
, dont bother with larger throttle body
, dont bother with injectors
dont bother with boost valve
are the gte t.b's basically the enlarged t.b's from regal at 250 quid? do these have the ICV?
i was talking to courtney sport today, no mantzels but they are developing there own inlet manifold, ready in about 5-6 weeks. be interesting to see how it perform's. talking of about 500 quid.
where else can i get either a new or 2nd hand mantzel or lexmaul?
