Turbo Conversion

[XR3ITURBO]

Hi Jay from UK here im currently in the middle of turbo converting my f - plate escort XR3I using a T3 turbo and -31 actuator from an RS Turbo but im still runing KE-JET BOSCH managment does any one have a clue if this will work? i know ill have to upgrade to sodium valves and forged pistons (high compression) has any one done anthing like this before? an if so what problems did you have? any help would be much apreciated.
thank you

oh by the way iv also fitted a 3" exhaust system with a 5" back box from a skyline R33 GT-R an it looks the nuts!!!!

I boosted a US 1.9, I'm still useing stock internals so I'm keeping the boost low to 6psi. All I needed to do was increase the injector size and use a FMU and a adjustable FPR.

Thanks for replying.
the problem i have is that i cant upsize the injectors as im running KE-JET BOSCH managment. larger injectors would cause servere overfueling makin the car a lot slower. i also have to uprate internals as i plan to run 1 bar of boost but 20 psi would be my ultimate aim

Yes, true I would also have the same over fueling poroblem with larger injectors, but that is why I'm using a adjustable fuel presure regulator. I increaed the injector size, than to make up for the exstra fuel I turned down the fuel pressure.
Idle fuel presure with 19# injectors was 32 psi.
Idle fuel presure with 24# injectors is about 20 psi.
Than when the boost comes on, the FMU increases the fuel presure to all the needed fuel.
Car runs perfect and has a perfect A/F ratio at all speeds.

theres no point in adding turbo goodies to a 3i engine because it won't work without all the electrical gizmos that the rs turbo has. you will also have to fit lower compression pistons otherwise your engine will go bang. save all the time and headscratching and buy a lightly damaged rs turbo and transplant everything off that car to your 3i. then you've got every correct bit, engine and box too.
why not just buy an rs turbo outright?
if you still want your xr3i, try finding a sencond hand 3i turbo conversion kit from the likes of turbo technics, janspeed and pace, which uses the original 3i injection and loom.

My car has normal electronic fuel injection and it works with boost. I'm using stock pistons at 9:1 C/R and it did'nt go bang. I dont know any thing about a 3i but I cant imagine it's weaker than the US Escorts???

i'm pointing out now, to advoid confusion that european escorts are very different to US escorts. the euro xr3i is a 1600cc CVH (same as your 1900) but has two different injection systems and pump out 105bhp. the euro RS turbo is also 1600 albiet modified head, lower compression, turbo, a modified version of the later injection (EFI as opposed to earlier MFI) the EFI has electrical gizmos such as ecu's to run it with the turbo. they have 132bhp. and you would have to spend near a £1000 to get any decent power gains.
my escort cabriolet is a 1600 MFI turbocharged with modifications and pumps out 185bhp.
I'm using a rebuilt RS turbo engine with standard MFI injection, RS turbo gearbox (has limited slip differential built in) fifth injector, pipercross filter in drilled airbox, janspeed turbo conversion, baileys dump valve, mongoose 2.5" straight thru stainless steel exhaust with 4" tailpipe and other tweaks.
the standard janspeed turbo conversion for the xr3i came with two bhps, 130 and 160 bhp. i have the 160 bhp version. with my better engine and mods has increased it and will increase further when i have my head polished and ported and high lift cam fitted with double valve springs and solid tappets.
AND i'm still using the original MFI injection. no needs for chips, no actuators. thats the bonus of the 3i turbo conversions. made by clever engineering companies to do it for you! finding a kit would be difficult as they are very rare now but only turbo technics exist. and you can still find the odd converted car or kits about.

hi there. Sorry to sound completely clueless here but I'm hoping you could answer a couple of goober questions for me:
I've just picked up a G reg Xr3i 1.6 with an EFI conversion on it. Its a very nice model and has stupid heaps of power (considering I were driving a 1.6cav L before it - bucket!!). I was just wondering what kind of mods I'd be able to add from the stuff you listed above? For example - would I be able to fit a turbo n dump valve (sorry - love the dump valve sound!!), or do any of the other jobs you listed like upgrade valves or port n polish? I think its stupidly powerful now but I was just curious about what can be added to it?
Also, could you tell me exactly what the EFI conversion is/does. What kind of power boost will I have gained from it and whats the xr3i without it usually?
sorry to be a nonce but I just wanna learn
thanks

I have an MFI XR3I that I am going to convert to RS Turbo spec - why not buy an RS Turbo -cos I know this one is straight clean and rust free with an HPI report.

Now... The XR3Is all came with MFI (Mechanical Fuel Injection) until early 1990 when they were converted to EFI (Electronic Fuel Injection).
There will be minimal gains in out right power 1-2bhp if you are lucky. The benefit comes in better driveability and fuel economy.

The different parts are that the EFI model has an ECU (Engine Control Unit), different injection and inlet system and is generally better. It can be chipped which the MFI can't. There are people who offer and say that the £I can be turboed with the MFI system but I think its a much better bet to convert to full RS Turbo EFI spec.

In the state's are Escorts never had the "Machanical Fuel Injection", it went right from Carb to Throttle body Fuel injectio than to MPFI.
I would have no idea on how to tune a machanical for boost, but it looks simular to what the older VW's have, thay have ways to make it work.

hi mate i was looking at your message cos i am converting my xr3i to a turbo with a janspeed conversion kit you have some pics but i cant see them can you post some more as i am having trouble fitting it with no instructions thanks dean
