Taimar/3000M manifolds

[clive f]

are the manifolds removed from engine from under the car, or can they be removed from above?

mine being a restoration job, the body was off when I got it so cannot remember what room there was in the engine bay.

does the starter motor need to be removed to remove the nearside manifold as well, I would assume this is the case?

for the manifold on the nearside i removed the heater, then lifted it out from the top.
I have stainless manifolds
Hope that helps

thanks, about to make some stainless ones and want to make sure they are an easy in / out job if possible.

Hi Clive,I lifted both of mine out from above with engine in situ. A little jiggly required.

Also I am the person on FB that asked you about them

The original manifold is woeful in terms of strangling the engine.
If your making new are you doing a better layout?
I know you work with stainless, what grade are you considering? It's a pretty tough call for most commercial grades.

From memory when I had mine off it was a case of unbolt manifold and starter and sort of lift out together? Don't think one comes out without the other................. of course I could be totally wrong, no doubt someone who's had more TVR's than I've had hot dinners will be along soon to clarify

This ^^^^^

Copy the original TVR design, and you will limit the engines ultimate power. Have a system like GAjon (and others) or TVRMs then you will release more ponies

definitely not along the standard lines, with what I`ve got in the lump its going to need to breeth, it will be a whole new system front to back, its the usual case of calculating pipe diameter and length required and then seeing how it can be packaged in the engine bay, at least the v6 goes down the sides unlike the griff and chim v8s going forward

I`ve done a few before, https://www.facebook.com/clivefppa

these were done recently for a Vixen.

am on the case, car being trailered to work tomorrow so I have something to work from.

after i had removed the heater the nearside manifold came out from top easy leaving starter in place

I hope you are referring to using software.

Best regards,

You may have seen this before its the Tony Law layout on mine, you can take it off in bits without removing the starter motor, still a sod of a job though.

May be of use to your plan?

I don't think you can remove the starter with the manifold in place.
For me first remove heater, second remove manifold from top, then you can remove starter.
I did it like that but i am a bit of a TVR Virgin

Hijacking the thread but I have orginal manifolds and pipe system that I don't need due to uping the exhaust system. If anyone wants it sure we can come to an agreement

Does the Tony Law manifold fit a 3000m chassis? looks like it has equal legth primaries so should give better preformance over TVR item.

Yes this was made for my M and specifically as a performance enhancement. It makes a massive difference over the original TVR manifold.

[clive f]

so how long is the standard starter motor? mine must be hiding in my junk pile somewhere as I`ve fitted the smaller hi torque motor to gain a bit of space.

if its possible to cater for the size of the standard starter with a removeable section then that will be the way to go.

Conservatively I reckon that the power increase is about 10% on a trick engine. So if you had 180bhp Essex lump on the standard manifolds you will be pushing 200bhp with this exhaust. My car (back in 1999!!) would just out accelerate my Impreza Turbo (235bhp) between 30mph and 90mph. Now given that the Impreza was a bit heavier!!, it suggests that I was getting around 200bhp. My Essex Engine had Powermax HC pistons, fully balanced bottom end, big valve heads, Weber 40DFI with custom K&N airfilter and Tony Law exhaust. GAjon's engine is quite a lot more powerful, that said it was never as quick as an Impreza in a corner!! (not that stopped him trying!!!)

Your only counting going forward though!

The biggest gain I got from this set up (and this wasn't on the GA engine which came later) was low down and mid range responsiveness.
The car became a pleasure to drive again like a standard V6.

You can move the No.1/4 cylinder pipes out and through the triangular bracing before coming back into the three into one...
