wat injectors do people use for the increased engine size above bieges or do you just turn the fuel pressure up ?

 

1.8zvh, i'm using greys

 

i should also add wat management as im basing it on std frst management

 

Greens 803's

 

hes on frst efi not cosworth mangemnt cant you people read. what is your spec 1st mate then i tell you what you need what is your bhp goal?

 

using megasquirt, didn't like the ofab setup

 

mtech v4 (megasquirt-ish) dark greens hoping for 300bhp if it ever gets built

 

you would need high impeadance lancia injectors which flow just a little more than bieges.

No point really as the batch firing system wont control them that well, and only running 1 bar of boost wont use them to their full potential anyway.

Be much better off with a sequential management system, decent injectors and a nice amount of boost. 1.5+bar at least if you have a good built engine with rods and pistons in a ZVH. Should see 300bhp with 4x4 turbo. Getting that mapped up will cost half as much as it would trying to do the same on FRST EFi. Seems a no win situation to me.

Loads of costs and still no power..

 

do you reckon im pissing in the wind with my expectations jano?

ive got
forged pistons
mictropolished crank
farndon rods
custom inlet
stage 3 t3 from cr t's
sitech zvh ported head
etc

can you give me an educated guess on what to expect from 18psi from what you have seen in the past.

p.s. had a customer equiery the other day recomended from yourself, much appreciated!

 

The turbo is the main part that will either give you good power or limit it.
Stages dont mean anything to me. There is no-one who determins what stage 1 is compared to stage 5 etc. Idealy you want a 4x4 comp wheel and housing with a .48.
running 18psi with oversize valves on a cvh would make 230bhp.

Next is that 803's wont run 300bhp on an 8v and top out at about 270bhp obviously depending on how good or bad the head is.

Ive seen lots of dash's done by you now, so have no worrys sending custom your way as i know it will be a good job done.

 

he's got the comp wheel and my .55 rear housing at moment and it's a 2.0 zvh he's building

 

Im building (nearly finished) a 2.1 zvh. Im running 346cc injectors. Not sure what im going to get tho or wat to expect????
Spec:
2.1zvh
T3 (stg3) but prob changing this to a t34
346cc injecctors
Crazycage zorst manifold
DTA ecu
Massive intercooler.

What power should i expect?
( sorry to hijack, might help you deside injectors)
