My version of a 4x4 nova that will get done!

[c20tbo]

Ste,

Will the transmission in the nova be standard?

Off topic what uprated stuff is available for the 4x4 let system?

[ste porter]

define standard? if you mean standard nova no
im using the 6 speed f28 with the bigger of the 3 transfer boxes with the standard rear diff which is the same as the holden commadore for starters
obviously the transfer box is beeing buggered about with as in its beeing locked and i know someone who can put a stronger v.c in

im going to suck it and see with a standard box for now but i have a spare which i may look into having built up to a decent spec

no matter what i do with the 500 bhp mark the vauxhall 4x4 system will always be a weak link 1 way or another its just going to be a learning curve finding ways of improving it as and when it shows its self up as a problem

ste, theres someone with a mk2 astra with a c20let but hes using a celica gt4 gearbox and putting 700bhp through it.

Lad I knows got a 300+bhp 4x4 Mk3 Astra GSi an it runs fine

You on about cooper mike ? see it at pod front wheels spin like fook and the back just sit there

Cracking car though

just to let you all know that this hasnt been burried just slow as of late as i have just got another cally turbo for breaking for peenuts and been at work alot but things are happening just not on the shell

got a few bits for my engine pluss another spare let so that will shortly find its way into a work horse

made a start on my new inlet got another set of steel rods got an actual let block not xe converted like i had before spec on engine as a rough guide so far goes like this

woosner low comps
eagle steel rods
acl mains
acl big ends
...arp 2000 rod bolts
arp head stud
oil squirters
block girdle
steel oil pump gear
ported head
reshaped combustion chambers
all new valves
cometic multilayer head gasket
double valve springs
custom plenum
custom made exhaust manifold
t70 turbo with custom machined housings on the hot and cold side for required a/r
40mm external gate
dta s40 pro
als maps (whooooooooosh bang, bang ba bang)
launch control
full throttle gear change
lightened fly and 7 1/4 ap paddle clutch
aiming for 450 - 500 at about 32psi !!!


there is alot more but that should give you a rough idea thats the bits i have so far only reason i have put the shell aside and started on engine for time beeing is because i now have 2 lets and a shed full of parts so i basicly want to have a sort through build up a standard let for the van build up the mental one for the nova ans sell all my spares off
basicly i dont want to flog any bits off untill i know i have all the bits i need for both engines

not got many pics but heres a fef to keep you going for now untill i get a proper update sorted for you

ok, a question, why have you got trumpets inside the plenum?

[ste porter]

this is such a broad subject and to be fully honest i dont fully understand it myself but i do understand the basics so the easiest way of putting it without getting myself all confused goes something like this

air under vacume i.e na moves in a completly different manor to air under presure i.e forced induction as a result the same inlet fitted to an na and a fi engine will can give massive cylinder presure and flow differences between each bore. air under presure follows the path of least resistance (basicly but there are other deciding factors but keeping it simple for now) so in an effort to smooth out presure differences across a common plenum the plenum should be tappered angles ect differ from engine to engine and trumpets should be added to help even out the flow.
