Turbo upgrade

[mattvik30]

Ive been following a few build guides on another forum tdocuk.com, which i know a few other members from here are also members of. Its a diesel forum and there are a few Fiesta zetec owners on there who have been getting 140bhp + from there 90ps lump by way of fitting a hybrid turbo and a remap. Ive currently decated mine, fitted a full straight through stainless steel exhaust, focus airbox with cold air feed, K&N panel filter along with a Vantuner remap. After all this i would like to think the van is putting out at least 115-118 bhp but never had it on a dyno to check. Anyway ive had this van for 5 years now and ive only done just over 30k in it, so im planning on keeping it for a long time yet. Ive already sorted the breaking out with performance discs and redstuff pads on the front and then the rear disc conversion kit from modyourtransit.com on the rear also with redstuff pads and performance discs. Anyway im looking for more power so have been looking into bigger injectors or going down the hybrid turbo route or if possible fitting a bigger turbo with a custom made manifold.

I know that there have been a few topics on this in the past, but they never really went anywhere as the price for doing a bit of trial and error was outweighing the potential power increases.

What are members thoughts on this and i dont mean the usual "its only a van, so why spend the cash on it" but i suppose not everyone uses there van as a work van and mine is actually the Tourneo connect so to me it is used like a car, plus with the cash ive spent on it over the years i could have bought a performance car if i had wanted, but where would be the fun in that!

Anyway i know there are alot of you with more knowledge of these engines than me, so just want to see what realistic options there are out there for more power?

Also what makes the 110ps engine 20ps more than the 90ps? It can just be a remap, so is it possibly bigger injecters or different turbo?

Cheers

The difference between a 1.8 TDCI 90ps & 1.8 TDCI 110ps

is the ECU map & turbo, If memory serves me correctly the 110PS has a variable vane turbo (ELECTRONIC)
& the 90ps uses the same turbo found on the 75ps which are fixed vane turbos

another point to note, The Axle ratio on gearbox, As the 90ps & 110ps axle ratios are not the same.

90ps MTX75 Gearbox axle ratio 4.06
110ps MTX75 Gearbox axle ratio 3.80

You can fit a Focus 1.8 Diesel 90ps MTX75 Gearbox standard ratio of 3.41 - Hence why the 90ps focus is alot quicker that the 90ps connect

As for tuning. ECU remap the max is around 118ps for 90ps
a 75ps can be remapped to 100ps max & 110ps right up to 140ps max

[mattvik30]

not sure what the turbo is on the 110ps but your right the 75ps and the 90ps engines have the fixed vane turbo with the manifold and turbo coming as one part. I think the 110ps turbo comes separate from the manifold.

What about injectors, is there a possibility that injectors from say the 110ps focus would fit into the connect?

No unfortunately they will not fit, As the focus 110ps uses the 1.6 DURATORQ TDCI DV6 engines !
This engine is also fitted to Fiesta, C-max S-max, Fusion and also fitted to Peugeot & Citreon HDI models (engine code G8DA / G8DD)
On these engines the Turbo is mounted at the front of engine.

The 110 1.6 TDCI injectors are longer than the 1.8 TDCI injectors & are different fitment - see pic

CONNECT 1.8 TDCI 90ps INJECTOR


FOCUS 1.6 TDCI DV6 110ps INJECTORS


I would not mind my Connect at 150 bhp, it's slow like snail compared to my 2012 Vauxhall Insignia 2.0 CDTI SRI nav which is 195 bhp !

I had my Connect TDCi remapped by Superchips to about 135bhp and it did go well.

The difference was pulling power, it had so much torque once you got over 1500rpm it would spin the wheels in third gear if the road was wet.
The actual acceleration was still not as fast as a car, although once again it pulled very well in fifth gear at motorway speeds.

I took the remap off due to issues with insurance, although I do still have the Bluefin unit with the remap in, so if I can get an insurance company that says "yes" to the remap I will re-install it.

The old mk1 focus tdci sport was the 1.8tdci engine (same as the connect) and had 130hp. The new focus has the different 1.6 engine fitted though yes.

Yes 130ps with a ECU remap.

Focus 2001- 2005 fitted with the 1.8 TDCI engines were only 115ps (Engine code F9DA) or 100ps (Engine code FFDA)

Althought the official "Focus Sport" was not released till late 2005
Even then it was still fitted with the 1.8 TDCI 115ps engine all that changed was the trim level

The Mk1 sporty versions were the RS & then ST170 from 2001 which was only 170ps

so what i the fastest option? the focus one?

In gearbox terms the focus gearbox.

if you put lets say a

Focus TDDI 90ps MTX75 gearbox Axle ratio 3.41
&
Connect TDDI 90ps MTX75 gearboxt axle ratio 4.06

together, both have identical engines & MTX75 gearboxes but different axle ratio, The Focus is faster on acceleration & faster than the Connect.

The result are the same with the TDCI,

Thats why when you get serious modders out there increasing engine power & performance they also change or rebuilt there gearboxes with slightly lower ratios.

but on the ib5 is the shift cables not on the front so will the cables reach? i assume the rest is a straght swap!!

tye

tye

The IB5 gearboxes will not fit in connects they for petrol engines not diesel, It has to be the MTX75 gearbox for connects

Mondeo mk2 1.8 TDDI IS also fitted with MTX57 gearbox

does anyone know what make the injectors are on a 2007 connect? ive just found out that the injectors are the same on all models of the connect from 75ps-110ps. They are also the same injectors fitted to the focus range with the tdci engine fitted.

Another option would be to send the injectors off to diesel bob as they can use your standard injectors but fit the heads from another larger injector to them. I have seen this done on the other forum where they used the standard fiesta injectors but fitted to them the heads from a bmw 330d i think. This resulted in the fiesta 1.6tdci lump producing 167bhp when combined with a hybrid turbo, but due to the excess fuel there was too much smoke, so the remapper ended up remapping the fiesta at 156bhp, which is quite impressive but also very costly at a price of 1,500+ but does go to show that there is that extra power available from the connect engine if you have the money to do a bit of trial and error.

I think that the most power van on the forum at the minute using the 1.8 tdci engine is g-mans and i think his van is producing 135bhp, so 150+ is possible

Sorry to say but there are 2 types of injectors for the Connect, its the same for the focus I engines TDDI &TDCI up to 2005.

All connect with the 90 ps & 110ps TDCI engines & Focus 1.8 TDCI 115ps engine uses Siemens Injectors, These have to been coded to your vehicle - (Electronic injectors) Part No :- 7T1Q-9F593-AB,
All connects WITH THE 75ps & 90ps TDDI engines & FOCUS 90ps & 100ps TDDI engines uses Delphi Injectors - (Non Electronic) Part No XS4Q-9F593-TF

If your connect is 2007 1.8 TDCI 90ps, your current injectors will be the Siemens Electronic coded ones.

Except for the Focus Sport 1.8 TDCI 115ps From 2006 onwards
from 2005>Focus II engines are 1.6 TDCI DV6, The Same engine is also fitted to the 2005> Fiesta 1.6 TDCI This engine uses Bosch injectors (Coded). These are completely different & will not fit early focus or any connects engines!

[SWtechnologies]

Reet so I'm goner look for a focus mtx75 then! See what happens when I fit it!

You seem to know all the facts and figures tho dude!

A 6speed option would be good tho eah?

[Kent Discos]

what about the focus box the guy on here put in the other day and all the gears were around the wrong way?
