hey guys im interested in twin turboing my xr4x4 does anyone no were to get the manifolds or other parts that are required or has anyone done this conversion on here whats it like thanx

 

yea talk to alan geffreys he'll be able to get everything for you need but trust me it wont be cheap if done properly,i did this a couple of years ago i got into thousands,got it all done then sold it and bought a cossy engine lol was cheaper than twin tubo 2.9 v6,
was a proper good laugh though but in my opinion just buy a cossy lump

 

Turbo Technics did a number of different twin turbo conversions, from 225 right to 323 bhp in the Minker. The kits come up on ebay reasonably often, seem to sell anything from £500 upwards. Alan now deals with these, he bought all the rest of the parts from Turbo Technics when they stopped doing the conversions. Really nice chap and knows his stuff.

I bought my kit second hand about 12 years ago, think I paid about £400 for it but it wasn't complete. I bought the DCU from Alan and used different intercoolers and boost pipes as they were also missing.

 

I had a turbo technics conversion xr4x4 years back was a bloody good upgrade on my 2.9 I tell you

 

Alan did mine as well many many moons ago, around about 1999/2000

Cost about £3k all in but it was awesome

Thinking about it now, it's probably easier to buy a cossie as you need loads of extra cooling and they drink like a bastard, 22 miles in half a tank was eye watering 10 years ago, imagine what that'll cost in today's money

 

cheers guys will contact him thankyou

 

22 miles on half a tank

 

Top speed runs at raf alconbury, I think I managed to get 3 or 4 in

Back in the day when petrol was cheap and you could get away with claiming 55,000 bhp from an air filter and a peco bb4

 

Mine didn't need any extra cooling and was a tad better than that on mpg

 

Mine has a copper core Pinto rad and DOHC fans and cools fine. The manifolds and turbo outlet pipes are thermal wrapped and I have a thermal cover round the ABS stuff. Under bonnet temps are lower than a standard 2.9 now. Mine averages about 24 mpg.

 

having owned 2 twinturbo XR4x4s and a 24v car i'd reccomend only doing this conversion if you can find a complete kit cheap. like 500quid cheap

if you have any bits missing youre gonna have to spend qutie a bit of cash getting stuff made up

do consider a 24v conversion. these are not as quick, but theyre 90% as good and piss easy to do and also very cheap.

some documentation there which will help you understand what bits you need and how to fit it

 

my first one:

proper quick it was (had dojj's old setup) but car was a shed

my second one:

don't let cowboy mechanics near modified cars

then i went 24v:


spent LOADS of money on those cars, in the end i bought a FOUR GRAND m3 which was 10x the car and never looked back!

 

this was mine running t25's/forged oversized pistons/big valve low comp heads on a megasquirt 2 ecu loved it just was expensive to build

 

 

i have a janspeed conversion in the garage that im debating on fitting to an XR4i but wondered if it would make a huge difference

 

if you've got it all get it on there will make a huge diffrence

 

yeah got it as as i broke a rotten car that had it on, are the engines changed in anyway or can the kit be bolted to my current engine, i do have a rolling road graph for 231 BHP but took that with a pinch of salt to be honest

may just be easie to drop it all in as if i remeber the sumps etc are modified with oil feeds

 

150bhp -> 200bhp

that will make a massive difference! plus the big midrange increase!

Turbo colognes do drive very nicely, they feel like they should have had the turbo as standard.

there's nothing wrong with them, the issue is that there are better engines available for the sierra that are also cheaper, so spending money on one is not good value.

if you dont care about value and just have a passion for this kind of thing then it's not a bad idea! i've always wanted to build a 500bhp 24v Cologne for a sierra if i win the lottery, but until the day i have money to BURN it'll never happen

 

i think the janspeed ones on the 2.8s just bolt on

 

janspeed ones were a bit rarer and there were ones with different bottom ends on the 2.8's

can't remember who had one on the xr forum but it was 260 brake and plenty noisy/quick until he rolled it into a field on a gentle drive home

 

Spotted this on Ebay

http://www.ebay.co.uk/itm/1987-Ford-...item4601b87dfb

Might be some parts worth having ?

 

go and have a look at skogenracing lads they use a lot of the 2.9 engines but using a single turbo conversion lik the gt40 etc they are getting massive power to basicaly stock engines near enough,i know they use megasquirt ecu with bigger injectors 2.8 head bolts as there not stretch bolts and a couple of other things

top boss sell manifolds too?? why no1 mention them bad rep??

 

expensive

 

There is a guy on e bay doing 24v ones some one put up a link they looked ok in mild or stainless.
