The whole point of doing my car, was to prove I can do it myself, if I make a mistake I have no-one to blame

I'm grateful to Tim, he is the person that told me about my second fault with the Gripper diff. When we met, we had a long chat about tuning and my car, he is really knowledgeable person.

i'm sorry that people wanting to work on there own cars instead of just handing over the keys & a cheque has upset you

By the way I have never used Tim for work either but you have to respect the ethos and ethic he instils in the work he carries out for his customers who become his friends.

The engine in that car linked earlier is not a motronic T5 engine. It is a late T5 engine probably the B5244 T5 engine from the 05 on cars. The most gains for less outlay on these engines has to be the head. When ported well and macthed on a flow bench the figures increase dramatically. Tim Williams proved this with IIRC Irfs car achieving 340hp with an 18t whites and a decat with only head work as the major thing done. I think that was the only work done on the car but the person to ask would of course either be Tim or Irf. I prefered the later heads on the T5 engine as they require much less porting and polishing.

im not saying that porting dont work it does but the cost can sometimes outway the benefits ,with a good turbo and intercooler works just as good then if you want more go down the road of doing the porting etc.but as i have said before this is my own opinion thats all.it also depends on budget for the mods involved

very true and im not slagging the guy off anyway im not into that rubish ethier

Porting can be quite reasonable these days with a lot of companies offering a service to T5 heads via CNC programs that have already been written as lots have been done before. Its when programs have to be written that things can become expensive. Also people that do the work by hand who have done the work may times can be much cheaper than other companies as they are very familiarwith the heads. If the ops car is being stripped by him and the head stipped also by him he could just take the head to someone for porting which will bring the cost right down. That way he could assemble the head himself and grind the valves in by hand although a nice machine 3-5 angle vale finish would be better.

my head on my 940 has got big valves and been machines to death but that is an 8v,the only thing im saying is i know peeps that have got mad power from engines just with rods and pistons and in the older engines like the redblocks peeps are running 400 whp with just a cam and turbo and ms so anything can be done but if the bugdet stretches to it then yes its a good idea imho.

thank you for you advice so far its been a big help im gona get a list and start geting the bits to do it so will be updates soon in my prodject section on here where do you get the bsm air filters what 940 do you get the throttle houseing off

[Volvostorm]

Fitting, a 9 series throttle body means you have to do a bit of wiring, the TPS is in a different place.

I had my 850 one bored out.

we are here to help mate and its the later 960 mate you want or you can mod a 2.5n/a 850 too but best get rid of the plastic plate in this one though thats why the 960 one is better.

the throttle position sensor is in the same place but turned 90degrees, the 3 wires need extending by about 2inches

with is the best choce to do between bored out 850 1 of 9 series are thay hard to find withch modle s do thay come on

ive done 4 of these 3intb mods wiring dont need to be done at all just fit the 850 tps no probs mate.

[Volvostorm]

I was wrong! Not for the first time!

[claymore]

aren't the 2.5 N/A tb bigger, just need to use the butterfly off the 960

they are same as the 960 but with that rubish plastic plate on it .i have a 960 tb and a 2.5n/a one too im going to get some butterfly plates made so the tbs will be the same then.

[claymore]

what's the purpos of the plastic plate, anyone got a picture

what's the purpos of the plastic plate, anyone got a picture

it was to make the car smoother to drive from what i understand.

[Volvostorm]

Its to slow the air speed through the body, by reducing the amount the flap opens at low throttle

I think that makes sense!
