what modifications does it take to get 200bhp genuine out of a series 2 turbo?

 

Not a lot tbh mate, Other than the usual filter, exhaust etc. You will want an all right intercooler, grs etc.

A stage 2 turbo and 16-18 psi will get you upto the 180-190 mark. A mild cam will help too. And a good setup!!

Some cars are able to fuel enough past this point others aren't imo its well worth investing an a 5th injector setup as the car will fuel SO much better off boost and you will see 200 bhp or over.

As a must! ensure all other components are in good health, no air leaks, good sensors and properly working fuel/ignition system, you will want cosworth plugs too.

All in all about a grand if using new parts and probably 4-700 if using a second hand turbo and cooler. Setup will be around £100.

Rob,

 

well thank you rob i currently have had a full rebuild ported and polished head, piper t2 cam chipped ecu, stage 2 clutch full scorpion exhaust pipercross filter bailey dump valve, still running standard turbo and inter cooler, still needs a set up tho, what would u change next if u were on a budget? cheers Neil

 

Intercooler to at least a double capacity to keep them air temps down.

 

intercooler then turbo and -31


i done intercooler,then turbo.then head then bottomend,and then went efi,not running 238bhp @ 14psi

 

Pace double capacity intercooler,80 to 100 quid from eBay,Theyre good for cars up to 200bhp.a stage 1 or 2 turbo with -31 actuator as said above should see 200bhp,maybe more with your existing mods.have heard 5th injectors are a bit pikey???

 

238 bhp bet thats fun in an old escort!

 

cheers guys intercooler next then turbo and 31

 

Don't forget a setup for your engine bout 150 quid

 

Good stuff, your well on your way! forgot you would need a chip to remove the boost limit

All you need now is a stage 2 turbo and a decent cooler! most will come with the -31 then you will happily see your figure or near to it! probably at lower boost too (due to your cam and head etc). I read in one of your other posts you may have a suspect fuel pump? If you suspect it i would change it, 200 brake requires a lot more fuel than the 130 our little rattle boxes had.... Fuel starvation can be terminal.

You might also need a lower temp thermostat and fan switch to deal, a GRP A coil is supposed to be worth while too. I suspect you will see the power you want at 15ish with your current spec.

Not at all mate, if you can't be fussed to go full on EFI or want a go between a fifth injector set up (a good one!!! MF2 etc) is superb. At the moment on mfi to get 200 brake his car will be overfueling like a pig off boost and even at low boost. Shit fuel economy, poor oil life... generally undesirable. A fifth injector mean the fueling can be turned down and supply met when it needs it. £300 well spent IMO!

 

I wouldn't bother with the pace cooler, they will do the job but won't keep air temps where you want them. GRS, radtech or pro alloy all the way. The GRS is the one most used and is a very reasonable price considering the quality.

 

Fair comments rob,I only suggested the pace as he said on a budget and would temporarily suffice his needs,as I mentioned to the op I have a bnib 05802 pump I don't need at the mo,
fifth injector may be a good stop gap but full efi is the way forward

 

A good gearbox

 

mot time first, but good to have some idea of what i will need to acheive the power i want from the car, im sure 200bhp would feel pretty sharp in an old escort im sure you would agree, its always struck me how helpfull people are on here compared to some other forums anyone ever heard of www.crx-uk.com it acually put me off owning my crx cause of the way they got on! if u didnt own the vtec model u were a knob as far as they were concerned, its the community spirit on here u dont find anywhere else!

can i ask if my fuel pump decides to shit itself will can this damage any thing else on my car or will it just cut out? cheers again Neil

 

I know what you mean about forums, before I got the escort I was looking for an impreza, I found one I was going to view, joined scoobynet with a very polite introduction explaining that I was about to go and look at what I hoped was going to be my 1st scoob and could anybody give me any pointers regarding things to look out etc.

Loads and loads of views, and not 1 person could be bothered to reply.

So I stuck with the blue oval

 

I DID THE SAME MATE, GOT BORED OF THE SCOOBY AFTER FEW MONTHS SO SWAPPED IT FOR MY RED S2 MAND NOW GOT NOTHING BUT TROUBLE AGAIN,THE JOYS OF FORDS

 

Hello, mine made 202 bhp wih 18psi boost, pace chargecooler, mongoose exhaust, -31 actuator, k&n filter and a good setup. Fuelling is fine with MFI and it chatters. Scorpion exhausts were proven to be restrictive on Series 2's. Pace intercoolers can handle about 190 horses, other options have been already mentioned. You need to think long and hard about transmission issues. Most of the series 2 people on here have spent many an hour doing gearboxes. I got a stage 1 from www.gearboxman.co.uk and got an ap organic clutch. You also need to consider handling, I got a spax adjustable kit off ebay that was 6 months old for 190 quid which has been spot on round track

 

I AGREE MATE SECOND TO NONE ITS A GOOD COMMUNITY HERE!

 

I agree mate, my daily driver is an old e36, bimmerforums is just hopeless!

good point mate,

yes and no, if it does it off load and fail's completely, no.... If it fails at full boost then possibly. Mixture would go really lean etc.

All good points there! i think its the back box on the scorpions that supposedly cause the restriction, don't think its overly drastic tho. Mine chattered on mfi too but genuinely off boost fueling will be well on the rich side... it physically has to be for fueling to be correct on boost.

 

Mine also chattered on MFI (you just need to run enough boost) but as Rob points out the fuelling will be really realy rich any where other than full load WOT and idle, hence if you do stay MFI a 5th injector would allow for partial fuel mapping resulting in better response and economy, although for a bit more money full EFI is the best option.

 

Who and how did they prove that scorpion exhausts were restrictive? The backbox looks smaller inside that magnex and mongoose...
Ive heard afew MFi's chatter... Like Karlos says must be boost related as they don't do it from standard.

My new Stage 3 T3 doesnt chatter as loud as my standard t3 did tho and im on EFi..!

 

I don't know how it was proven, but if you look up a scoprion back box theres like a 2" tube, so it goes from 2.5-3" down to 2 which was a bit random of them.

 

a decent clutch too

 

Rob, i noticed that when fitting mine... My NA system had the same size box internally, maybe its to keep noise down or back pressure up?
Eventually i'd like a scorpion 3" system as ive got a 2.5" atm, hoping the 3" has larger internal back box!

 

probably to keep costs down tbh mate.

 

will this be 200 at the wheel am i right?

 

flywheel i would say, not many people refer to the wheels when quoting power, all manufacturers quote flywheel horsepower. 200 bhp at the wheels will be more like 230+ at the flywheel on a FWD car

 

As far as i am aware scorpion nor magnex made a 3 inch bore system only mongoose, the scorpion is restrictive as the internal diameter of the silencer is no bigger than the standard rs turbo exhaust from out the factory!!! So mongoose is the way forward or have one made up by the likes of hayward & scott etc

 

Although its worth pointing out that a little back pressure in a turbo car is a good thing as not enough can allow oil to bypass the seal in the exhaust side of the turbo and make it a bit smokey

 

Yeah at the Fly mate.

 

woohoo my thread has taken off! lol so im gonna need to get rid of the scorpion system then!

 

No, not really mate. Far bigger restrictions than the exhaust. My car has a scorpion exhaust and made similar power to your target with a much worse spec.

Rob,

 

who talks in flywheel bhp?
thats pub talk.
wheels is where its at boys,cmon.

 

Indeed it is mate, but all manufacturers quotes are @ the fly so in the UK any way nearly all tuners will quote flywheel power.

Wheel power is far more accurate, but not quite so penis extending

 

everyone ive ever spoke to lol, where does it end? will we quote power to weight ratio and available traction next? because thats where its at really.
