Is it a requirement to change standard actuator on T3 (sapphy 4x4) to -31 when upgrading to stage 1 MSD L8 chip?

Thanks
All the best for the new year 2010

 

Don't know but i would as they're not expensive.

 

Ok, but will a -31 cause any difference as compared to a standard actuator?

 

you have to change the actuator for a -31 its gives you more boost over the standard one

 

Correct me if I'm wrong but doesn't the new chip (map) through the amal valve control the ammount of boost??

 

Click on this link which explains why you need the new actuator: http://www.motorsport-developments.co.uk/actuators.html

As it's a Motorsport Developments chip, you can check on the same site for what is required to run your chip. Or you can call them to find the same info.

 

if u've got a new std actuator it will be good enough........if ur setting the car up urself and have a boost guage then u'll be able to tell if its holding boost.....if not buy a -31..................

 

....ur "jetted" amal valve and ur actuator

 

had a -31 when mine was pe stage 1

 

I do have a boost gauge fitted and working, so I can check my standard actuator performance. What do you exactly mean by holding boost on a standard engine on a standard chip? Should the 10 psi boost pressure hold for as long as I maintain the same throttle opening????

 

no fella....u'll get a boost spike then it'll tail off a couple of lbs...............

 

-31 and around about half a hole of preload, std amal jetting should be ok on stg1

 

Thats exactly how the boost pressure behaves on my current standard setup, so I may safely assume that my actuator is up to the job and proceed to purchase the MSD chip only and then again watch how boost behaves then proceed accordingly as regards to the purchase of the -31?

By the way whats your opinion about the MSD stage one chip vis a vis other chips on the market??

 

'around about half a hole of preload, std amal jetting' can you please explain this . i am new to this subject

thanks

 

did the chip come with instructions?

 

......dont think he's bought it yet......

 

ahh, well if he does it will come with full instructions explaining how to achieve the boost level

 

Have not yet bought the chip .

 

Hi mates

whats your opinion about the MSD stage one chip vis a vis other chips on the market??

i want to make an informed decision before forging ahead with my upgrade.

many thanks

 

stg 1 aint really a big deal to be honest....dont get me wrong it transforms the car into what a cossie should be, but an off the shelf chip will be near enough the same off all tuners........good thing is though MSD are having a sale so deffo worth a punt....

 

As above they have a sale on just now,but just go stage 3 and be done with it.

 

where do u live fella........not being funny but as u know very little about cossies then u'd be better off getting it set up by a pro...............instead of u fookin about with it......

 

My guess is malta pete.

 

yes i know stage 1 is not a big deal but to go beyond would mean that i have to replace my T3 turbo, injectors, map sensor..... + I have read that the 4x4 g. box and transmission will not cope and therefore would be risking breaking.....

 

You'll just want more power believe me.

 

Yes I'm in Malta....not much roads where you can use all the power from robust power upgrades.....no track days just quarter miles which I am not much into

 

.....u'd get more power from ur t3....but u would need map sensor (Ł60) and bigger injectors (2nd hand greens....Ł100 tops)........and ur trans will cope with all a t3 will give......

 

What about head gasket.....its still on standard one.......and head refubishment while am at it (valve guides + followers...) the bill is rocketing

 

....how long has the gasket been on/what gasket is on it...????.....and if it aint broke dont bother.......it's upto u, it might last a day, month, year....who knows....or splash the cash and get ur head cleaned up, skimmed and a grp A gasket put on.......(i'd leave it till it blew)

 

the previous owner said it was still on factory gasket. is there a way i can verify this obviously without removing the head??? engine number starts with LM so its 1990. is it possible for gasket to last this much when properly taken care of?

 

I would also leave the gasket, cos it`s really annoying if you remove the head and you find an uprated one.
I am in the same situation at the moment, upgrade for stage3 and dont know what gasket is in. So wish me luck

 

msd chips are fine fella!!!very well known!

 

I think you are wise to go for stage one, I certainly would not want to go any further than this with standard HG, as standard the HG is very fragile.

Stage 1 will transform the car from what it is now mainly due to the extra torque produced.

The above gives you the most "Bang for Bucks" without buying extra hardware excluding the likes of Gunship which put you in the same boat as above with the HG.

If you look at the engine sometimes it is possible to see if a aftermarket HG is fitted you can see if it's multi layer etc.

Martin

 

I'll see if i can see any layers with some proper artificial light conditions then.

Martin because of the very limited traveling distances available over here I tend to agree with your reasoning as regards the upgrade. It is only very rarely that I am able to go over 4500 rpm in top gears and that is for very short periods of time (2-3 minutes max) due to the short suitable stretches of road available for safe driving , keeping in mind some relaxed braking distances. What would be best is plenty of torque at lower revs--short acceleration blasts

 

Good luck then

 

defo go to msd as in Malta think i,m right in saying that fuel is a much lower octane and im sure the are the ideal chip writers for it , just a wee thought

Trying to present the fuel analysis in better format:

This is the analysis results for the Petrol available in Malta. Which one would you use for your cossie

 

the highest octane.........97ron.................

 

97 RON LRP has got manganese content at 18 mg/ltr minimum is that good for the yb engine?
