Isuzu turbo diesel tuning guide

hi

I've rigged up a shield on the subframe but one heavy puddle got through the filter van conked out but luckily was ok

Why not try a standard cossie 2wd alloy f.m.i.c. can be picked up off ebay for 40quid or under, much bigger than standard

Its always been laggy its standard turbo, nice boost when it comes on though does use juice though

20quid total bargain

I/C is mounted next to the radiator. There are only two sorts of bumpers for Cavs, the normal one and the GSI/turbo one.

Laggy? Uses juice? What's wrong with it?

Mine starts spooling up at about 1900, and I'm on full boost by 2200.

He might be thinking of the airbox on the manifold? laggy ie comparing my mums focus td's spool up much lag. 10quid 50-60 miles maybe its the eccentric cone i put it back wrong, i lined it up with the dimple on the end still juicy hmm. Might have to take a look, fueling is up 1/4 but anymore and it starts reving and no amount of idle fiddling will bring it down so 1/4 is fine.

any pro's and cons too doing this?

ive a astra

yeah i did look at that cossie one last night on there, didnt no if it was different tho, im trying to aim for looks, and performance at the same time, so want it front mounted, on show

plus it will get better cooling then hiud behind the bumper

**the flash** · 09-01-2008 20:21

if you doing that why not get another manifold and mod it to fit a t3 and make use of that big i.c.

**reno** · 09-01-2008 20:25

would it be easy to mod do you think?? using a orginal item

**the flash** · 09-01-2008 21:06

Dont think it would be that hard remember you need to be a reasonable welder and you need an arc welder http://www.mig-welding.co.uk/cast-iron.htm for welding iron

You'd have to have a look at the casting on the manifold but you might be able to cut an rs manifold up for the mating point to weld onto the isuzu one.

see eveythings as one so just matings the issue

some interesting stuff to read on Vxon, some people are saying you can bolt a turbo on from a montery which sounds interesting

Turbo from a 3.1 Isuzu engine goes straight on apparently.

**the flash** · 09-01-2008 21:23

if you can find one

Why is my engine overfueling so much? eccentric cone?

**reno** · 09-01-2008 22:31

aww good stuff, anyone know what sort of bhp the standard item will run max? or ideas, figures on the old, and the 3.1 trooper turbo?

with upped boost and fuel, what are you looking at? 90bhp? on the standard item, with mayb a cone filter

**the flash** · 09-01-2008 22:41

its about the same as a 1.6i gte nova

**montytronix** · 09-01-2008 22:41

I have an old diesel derv and got [alleged] 120mph 2L8v - the final drive is so high the cam pulls at [alleged] 95mph
I put a viper induction; 50mm striaght thro s/s zorst; twin plastic performance back box; [used a bleed valve was gr8 till HG went] melted 4th cylinder due to veg oil and had it rebored 1mm oversize; ported and roughed out inlets
iam now looking to pumb in an intercooler just for the hell of it - when i weld the rust holes for the mot lol

**the flash** · 09-01-2008 22:48

what car and engine?? not a meeestro is it?

**reno** · 09-01-2008 22:49

Yeah. Mine went in exactly as it came out. I put a mark on it so I knew.

Guess again.

**reno** · 10-01-2008 15:35

108bhp then, not bad is it, so 120bhp is possible then. smiles all round

**Grim Reaper** · 10-01-2008 15:39

Thank you very much, squire.

It's lovely to drive around town.

**Grim Reaper** · 10-01-2008 18:42

the line makes me horny...

lmao

**the flash** · 10-01-2008 18:51

Thought as much

when i took the cone out holding it in my hand, i thought **** i'm supposed to mark this

How can i check the fueling, pressure gauges?

**zak_godsell** · 18-01-2008 18:34

i have now upped the boost/fuelling on my cav 1.7td cdx

.it pulls a lot better,not so bloody slow now.i will have to get it on the rollers to see if i have cracked the 100bhp mark

**the flash** · 18-01-2008 18:47
