So if I went for a 170 engine I need to Change inlet and exhaust manifolds. And would I see a great deal difference from a std black top on 45s. I know throttle bodies would be better. But my 45s are near new.

That's a question! Std B/top with std injection rated at 130 - 135hp, Guessing twin 45 DCOE's might squeak that upto 150-155hp but lose a bit of drivability. Jenvey 45 DCOE pattern TB's and aftermarket ECU controlling fuel and ign. will be about 170-175hp. 170 ST's are potentially adding another 20hp on top of that. B/top's with headwork and cams reportedly are 200+hp area but probably a bit more extreme for road use - would certainly test usual T9 gearbox!

Thanks for all your replies gents much appreciated. I might just stick with my blacktop engine and just get some head work done along with a good set of cams and try that with my 45s. Then if I sell my Weber’s will change to Tb. Also got another problem with my brakes (if anyone fancies to help) I don’t just want to keep putting up problem after problem and becoming a pain in the backside.

Col is right. Its been a bit so quiet this week I wondered what had happened to everyone so post away. Im glad you decided to keep the engine you have and make a few mods rather than the change you were proposing. Thats what I would do also in your situation.

What's up with ur brakes

Here we go. My mk1 Escort has got a bias pedal box fitted (already on the car when I got it) I have since fitted new front brakes 4pots with discs, pads and pipes. The rear disc conversion was already done. The brakes have always been ok, until the other week. I drove the car to work and all was fine. On the way home the brake pedal just went to the floor. I pumped them a few time and it was slightly better but not good. As I was nearly home I nursed it back thinking it might be a pipe gone. A few days later went to the garage to have a look for leaks but couldn’t see any. I tried the pedal again and it back to normal and can’t rectify the fault. Now I don’t fancy taking it out In case it happens again

4 pots. What make are they

Hi-spec

Have u checked the seals on 4 pots. Have seen hi spec fails before hand. Looks like a case of eliminating all pipework and seals 1 by 1.

I thought pipe work problem. But now they seem to work ok again. So can’t be leaking fluid. All the levels are still up. 

[mpdevelopments.uk]

Strange one. IN the past I've had hi spec calipers flex under braking and causes weepy seals.

It that case I will them stripped and have a look. Nice one. Thanks

just dont fit a vauxhall engine!

[Bavman]

Could it be a master cylinder having a funny 5 minutes. 

[Bavman]

Funny you said don’t fit a Vauxhall engine in it. That’s what was in it when I got it. Xe on bike carbs. Did go well but it went bang on me lol

[mpdevelopments.uk]

U can pull back cover seal on master cylinder. Where pushrod enters it. And see if it's wet at all

normally just drop their water!

[Bavman]

Your right it did I took it out and sold it complete with carbs and ecu set up. It looked a right mess anyway. Looked like it was painted with a broom

[katana]

Air bubble I reckon - it does tend to hide only to get vibrated out later.

[khanlad]

You say the levels are still up, where they were or above min? 

[Bavman]

I believe where they were. 

[mpdevelopments.uk]

I'd say. Double check all pipes fittings and calipers for weeps/ leaks. If all seems dry. Pressure bleed system system and see how that goes.

Surely if the levels are where they were there cant be a leak? If its leaking they would have dropped? Or trapped air, if the air has become untrapped it would be replaced by fluid and again level would drop?

[mpdevelopments.uk]

Khanlad.
I would agree. But to loose pedal while driving. Something.s not right.
Case of eliminating everything
