throttle bodies on x-flow??

[mad max]

can this be done & for how much?

wonder if they still sound good?

 

u can run but u cant hide!!

[oilyhands]

Yes it can be done, but it wont be cheap..

 

TBs say £500

Linkages/filters etc £150

ECU say £600

Tank mods to prevent surge say £150

Fuel pump £100

Fule pressure regulator £50

Secondhand injectors £50

Fuel pipe £30

Mapping £120

Lumenition eye for distributor trigger £30

 

A set of TBs sounds exactly like carbs, its only the engines with plenums that sound naff.

 

There is a hefty section on converting from carbs/clockwork ignition to mapped ignition and injection in the EMS article here. It may help

blimey,best just have the carbs looked at then.

Weber Alpha do a kit that includes everything you need to covert to throttle bodies for around £1,500/1,600 + VAT. Down side is that you need a Weber Alpha dealer to tweak it.

3D mapped ignition with well set up carbs is very nearly as good on a Crossflow and a lot cheaper. It really improves the part throttle stuff.

 

Expecting howls of derision for this from die hard injection enthusiasts.

I can testify to that, went from a 234 to 244 cam and Weber Alpha management at the same time. The car is easier to drive and responds better on part throttle despite the cam upgrade!

It's pretty much the same conversion as with a Vx - from my experience, budget around £2500 including rolling road mapping.

 

£3000 if you're paying someone to do it.

Barry H has done this, Barry where are you ?

 

Can fully endorse what Roger says about 3D and carbs. It is very good, probably the best improvement I ever added to my cross-flow.

I've done a couple of mapped ignition only conversion on xflows both using Emeralds M3D, one of them to Kevin Strawbridges car, it's a little fiddly with the wiring, but pretty effective, part throttle and off-cam improves considerably making the engine much more tractable. Better economy and a rock steady idle are also benefits. Costs were around £650 which includes the ECU, throttle pot and lumenition eye for the distributor. The conversion takes about 4-6 hours to do properly.

Blimey! I was expecting brickbats for that suggestion, not glowing endorsments.

Here I am Graham - a day late but I had to get to Curborough yesterday for a sprint. Lovely day!

 

Yes I went to throttle bodies, dizzyless, etc., just over a year ago. Cost about Oily's estimate. Benefits much as those claimed for 3D - very tractable (drives cleanly from 2000revs in 6th gear through to 8500+ on a 254 cam), instant throttle response and a lovely noise.

 

I can't comment on the 3D but if it is only 80% as good as throttle bodies at half the price then it is probably better value.

 

Either way is an improvement.

Roger King did a Weber Alpha 3d ignition conversion on my old 254 x-flow back in 98 and it certainly improved things. Cruising was far more pleasant, pick up much better and fuel economy improved from 18 to 22 on a decent run. Power as expected remained identical. Well worth doing.
