Help with injecters for a let

[burnhamshaun]

Need to know what injectors to get for my let into mk3 astra project also if anyone knows if the xe cam swap works

[vanquis]

LET engines come with yellow injectors as standard, have a set here if you want some (PM me)

and yes the XE inlet cam mod works, if you get an adjustable cam pulley to go with it at the same time, so you can set the correct timing to get maximum gains (~20BHP)

[burnhamshaun]

was looking at a good upgrade option but havent a clue whats the best to go for but just brought a set of xe cams for £50 just need an ajustable one lol

[burnhamshaun]

wanted ajustable cam for the xe cam swap

[Nemesis]

Use normal yellow injectors if the engine is standard or nearly standard.

na got intercooler gonna get evo 5 chips also and want to do the cam swap

[EY]

Yellows are fine for EVO5.

[burnhamshaun]

what about the cam swap do you think it works and is worth while

[EY]

Yes it's worthwhile if you use a vernier to set the timing correctly.

So yes, it will be a lightly tuned LET

[burnhamshaun]

any idea where i can buy one from and which way round do they need to be any ideas

Demon Tweeks do vernier pulleys, as do SBD developments, Regal, Courtenay, Chris Astley...

Put the XE inlet cam in, not the exhaust one.

[EY]

Adjustable verniers made (Square tooth)

nice one mate this has helped what about injectors also evo 5 chips any ideas on where i can get these regards shaun

[Nemesis]

Evo 5 works fine on standard:
Injectors
Pistons
Rods
Head
Headgasket
Cams
Inlet manifold
Turbo

You should change:
Intercooler
AFM to turbo pipe
Spark plugs (regap to .7mm)
Fuel pressure
Oil and filter

You should check:
Fuel pump voltage
Cambelt/waterpump age

ive got a frontera intercooler to wack on how go you regap the spark plugs and what does this do oil and filter will be done what fuel pressure should it be and how can i check and what do you mean by the air flow meter to turbo pipe regards shaun

[Nemesis]

Get a feeler gauge to gap your plugs, and tap them down until the .7mm blade passes through (only just)

Not sure on fuel pressure, have a read up on the Vmax website

The AFM to turbo pipe is awful as standard, and can collapse under vacuum causing all sorts of problems. You're best getting a silicone one or a metal one.

[burnhamshaun]

got the afm pipe sorted now and what benifit do you get from making the sparkplug gap smaller

[EY]

EVO5 runs higher boost making it harder for the spark to jump, closing the gap prevents missfires.

[Nemesis]

You need a smaller gap with increased boost to ensure you get a good spark. NGK BCP7EVX plugs are ideal, as are Ford RS Turbo ones (standard ones). Don't bother with anything else. You also want to check the condition of your cap and rotor arm as running more boost will show up flaws in these!

[burnhamshaun]

cool any idea where i can get them spark plugs the ngk ones also will i need better injectors as ive been told running standard ones with evo 5 can lead to engine failure

[burnhamshaun]

ive found some on ebay for £$ each does that sound right

[EY]

www.spark-plugs.co.uk

[burnhamshaun]

£4 each

you dont need different injectors, you just need to raise your fuel pressure.

You can buy NGK's in halfords for about 12 quid, just look ask for a set of 1988 Ford Rs Turbo ones.
