As subject states really, just after a quick idea what sort of power a series 2 would be running boosting at 10psi on the standard turbo.

cheers.

 

160 bhp ish. Certainly wouldn't expect more.

 

150ish probably

nothing mega

 

ok what from a standard series 2 could be done to gain more power out of the engine safely.

in terms of what can the standard engine handle bhp wise and what boost is safe to run on the standard turbo.

 

there are many tried and tested tuning routes for the RS turbo. unfortunately there isnt really an accurate definition of "SAFELY" as you'll probbaly be talking about a 15 year old car with 100k miles and unknown hstory, you never know what could happen.

generally speaking most people tend to start with the basics: exhaust, filter

then youll want it chipped (which just removed the boost limit)

then run some healthy boost through it (which WILL shorten the life of the turbo if standard)

you'll probaly be knocking on 170-180bhp

deffo take it to a tuners with experience of RS Turbos tho, as youll probably find its not set up properly and running less than standard power anyway, i recon about 80% of them are

 

Well i know the car im interested in does have history and its only had 4 owners, its also had the valves/lifters replaced and engine reconditioned not long ago, also a reconditioned fresh turbo.

It has an exhaust and filter already fitted aswell as a cosworth fuel pump, airtec front mount and LUK clutch.

So its a nice base to start a little project on, i dont want to go silly with it really just get whats available without having to rebuild the engine etc. Like you point out there are many tried and tested methods i was just wondering what will probably be the best route to take for a car in that form.

I assume the following then..

Chip/Remap
Maybe a little more boost with electronic boost controller.

 

Take to Karl Norris!!

 

If the engine recondition, brought it back to nice n standard with good gaskets etc, then it just needs some more boost to be reasonably quick for a small car.

my rst made 190bhp and 206lbs torque

std engine, cossie turbo, chargecooler, chipped ecu, running 14psi, exhaust filter breather

 

Shoot me for saying this but.. Who is Karl Norris? what does he do?

 

Builder of the fastest and most powerful CVH's.

Top guy. Never took my RST there (was still using PJ at the time ) but was very happy with the work he did on my cossie.

 

also you dont remap them as they use mechanical fuel injection. chipping them (99% of the time) is literally just removing the boost limit! lol

 

Dude, that website is awesome it breaks everything down into stages which makes life easier for me.. im no stranger to turbo setups as i have had a skyline,200sx and various other cars in the past but obviously each marque has its route to power by changing various things!

 

lol, my bad - will have to get researching on this mechanical fuel injection a little bit more

So basically the so called "chip" is just a plug the laptop in and remove a boost limit on the ecu?

Or is it the more crude way of doing things and replace a hose that sometimes has a little brass restrictor in the pipe lol.

 

no laptop involved

alls it is tuners take the ecu aprt desolder the original chip and solder a new chip in it

 

Turbosystems/Karl etc can alter ignition timing on the chip, but not many others can do that.

 

what kind of 0-60 time would one running say 170ish bhp be capable off?

 

Depends mate as being front wheel drive they can be a pain to get start off without bogging down or lighting tyres up,id say with 170bhp there must a high 6 to mid 7s.

 

as above.

the chances of the car's suspension being in A1 condition (rare for an RST) are probably quite low so i'd expect it to be worse than the book time of 8sec if running std power

 

just 1 thing i find strange on the nms website.Stage 1 This involves the fitment of a Garret –31 actuator, replacement spark plugs, a special bleed valve system which eliminates boost pressure drop at high rpm's, boost is set to hold 10psi and fuelling and engine are setup to suit. This is a basic conversion that really transforms the standard car and will give around 150bhp. Stage 2 Stage 2 involves the fitting of a new EMS "chip", and coupled with a Garret –31 actuator, a bleed valve system and new spark plugs the boost is now raised to 14psi. sorry but i thought you used a bleed valve to fool your standard ecu,saying its standard pressure but its not,10psi max.(if you couldnt afford a chip that is)and the chip changes everything,and you remove the bleed valve.you dont use both at the same time.and a t34 IMO is a bit large for a 1.6

 

no you misunderstand what a bleed valve does mate.

the bleed valve is a mechanical device to allow you to raise the boost pressure. you actually have one as standard! karl is justtalking about replacing it wht a proper one thats also adjustable.

the chip on an RST is what allows you to raise the boost pressure above the standard 10psi boost limit.

the cihip on an RST does not change everything, it uses MECHANICAL fuel injection not electronic fuel injection.

as for the T34, if you want big power you need big turbo, there's no way you can get a small turbo to do big numbers without exploding its all physics

 

well theres no mention of a standard bleed valve in my haynes book m8.and i know its mfi,and the chip does not change everything,that was the wrong word to use.the fact still remains a t34 is too big for a 1.6,and it would not be a fast road car,rolling road figures all bollox anyway,and thats all most people are doing,is chasing bhp figures

 

im pretty sure karl only advises a T34 on his big spec RST motors where the T3 cannot produce the power.

the fact is if you want a big power car you do need a larger than standard turbo.

the bleed valve on the car is commonly refered to as an "AMAL VALVE" (it has the word AMAL ritten on it but its actually just some sort of manufacturers stamp)

this is an electronic 2 way switchable bleed valve used as standard to restrict the boost on the car if the ECU chooses to

 

The standard boost control system is done via the amal valve, from what i understood(possible wrong) NMS removes the amal to replace with his own bleed setup.
All the chip does is raise or eliminate boost cut and alter ignition timing.

 

rs1, 99% of them dont alter the ignition timing

karl is one of the few tuners who do offer a service to modify the ignition map on an RST tho

 

ok well i cant seem to find the amal valve on my car,i had wondered about this.my car have a superchip and the other ecu has a superchips sticker on it.has my amal valve been removed??

 

am i right in thinking that the chip removes the fuel cut and alters the fueling setup and then this in turn allows you to fit an adjustable bleed valve and raise the boost to what you want?

caus eif your saying the chip raises the boost that cant be right, the boost must be raised by the bleed valve.

 

Mine has a 31 actuator,k&n filter,mongoose exhaust,piper 285 t2 cam kit,airtec full frontal inercooler running a bar of boost and it made 143 bhp(makes me want cry)So my advice is get it set up and a power run to see what you're starting with.Mine going in for rolling road set up next week cant wait.

 

143 bhp, id want to cry aswell with them mods and that power - 13bhp up from standard is not good is it!

 

has to be something silly up with it, seriously needs sorting before he does a BIG NO NO, 143bhp i`d be crying too.. don`t know what mine is up to power wise but hoping for a healthy figure when it goes on the rollers as i think i have done some good mods to get some more out of it, 220bhp is my goal, i`d be happy then

 

Hi there I have built a cvh turbo to a tuners spec

Standard conpression wossner pistons and pec rods

Ported head with newmans cam

The car is going to be running on stand alone managment

The question I have is how much power will I achieve from standard conpression without detonation?

 

What turbo and injectors are you gonna be using?

 

I don't know it's up to the tuner but is it possible to get high power figures from standard compression? I'm told by tuner 300bhp is possable

 

There are many more variables that effect when an engine detonates other than it's static CR.... cam profile, manifolds, turbine size, intercooler (MAT/ACT ultimately), fuel type, etc.

 

My series 2 made 189bhp @ the fly, and 222lbft. Set up by Jamie @ Evotune in Durham with the following mods;

Stage 1 Bayoo Chip
Dawes device running 17psi
Airtec radiator with Toyota red coolant,
Pro Alloy front mount with twin spal fans
Pipercross induction
3" Mongoose with 4" tail
Baileys oil separator/breather
NGK plugs
Gas flowed throttle body and inlet manifold
ARP studs nuts and bolts
AP paddle clutch, lightened flywheel
Lightened & balanced crank
Mahle pistons
Wossner rods.
Full samco hose sets.

The cam is a unknown at the moment, but looking at the rest of the engine, I have to assume the head has had some work.
Still running standard turbo & actuator, but have some room for improvement.

 

If you were EFI and had a bigger turbo the engine is good for 300bhp+

 

Whats a dawes device?

 

On standard compression Karlos ye?

 

My rst made 189 bhp on 1 bar with drilled air box piper exhaust airtec cooler and -31 as far as I know the engine was standard
