I've been told lots of times this engine doesn't respond well to tuning.
As stock in my TVR it should give 160 bhp, not a bad figure. And should be fun to learn to drive it with this performance, but knowing me I'll
hanker for a bit more pretty soon.
Does anyone know of anyway to get a reliable 10-20bhp pretty cheap, I'm not after miracles.
The 2.9i has a bit more power and a proper injection system, would be interested to know if anyone has megasquirted one and got better performance
than the stock ecu. It doesn't seem to be worth swapping engines as the 0-60 time only drops by 0.1s, so a bit more go out of my current engine
woudl be best.
Thoughts welcomed
forced induction would give you what you need and more.
don't know if it's any help, hell not sure if it's the right engine but this may help

if not apologies
I've been pondering this one for a while, I've got 1st refusal on a Taimar with an old 2.5 essex V6, I'm thinking along the lines of a
well sorted 2.0 Zetec, or ST170 if I could get hold of one.
Those old V6's have had their day IMO, when a 2.0L can produce more power, more economically, and with much less weight, BIG drawback is you
loose the V6 burble.
hey, finally an area in which i have some expertise 
.
I used to have a capri 2.8i S.
that said, the best way to tune a 2.8i is to replace it with a cosworth 24v 
edited to be more constructive:
the restriction in the 2.8i is in the simaesed exhaust ports therefore changing the induction gives meagre gains (thats to bike
carbs/downdraughts/throttle bodies/turbos). The best option IS to turbo charge, but the limit set by the way the engine vents exhaust gases is set
VERY low.
The cosworth 24v seems like a fairly pointless change when you consider that like for like its not a stupendous improvement over the 2.8, but in terms
of durability and flexibility it blows it out of the water. Theyre not ridiculously expensive for a very well built engine either.

iirc the 2.8i is rated at 180bhp, the injection setup it’s very basic and dead easy to install. Mine has had both the cabs and injection fitted. Not
much heavier than the pinto despite the claims of others, for example the ride height of the falcon went down about 1/2 an inch at the front when I
replaced the pinto with the v6. Great engines with tonnes of torque and a nice sound. A bit thirsty though

I agree with Craig. 24v would be my choice, you won't get anything meaningful out of the 2.8 unless you throw money at it in my experience.
Although the numbers aren't much different, I found the 2.9 (12v) had a noticeable extra chunk of torque compared to the 2.8 and the swap
wasn't difficult to do. The 2.9 also has a full compliment of exhaust ports so should respond to tuning better than the 2.8 once you've got
used to the extra shove!

Interesting,
No new options then:
1. Force induct (did fancy a supercharger)
2. 2.9i, low hastle, cheap, extra 8 bhp
3. Cosworth, mmm could be tempted, whats the output ~200bhp?
4. Fit a V8
Putting a 4 pot in a tvr would be sacrilage.
Anything over 1k would put me into sell mine and buy the V8s version with 240bhp.

Willie Green (classic car racer and second hand car salesman ;-) used to have a Capri with a Cosworth V6 and when I worked for Wheeltorque he used to
instruct and went out in my S3c with me at Hethel. First thing he said was "You know you can put the 24v motor in this don't you." His
Capri was rapid at the Ring and Spa He could run rings round anything and often did on the way over from the UK! I remember he said he had different
maps for road and track. Its the engine I always wanted to upgrade my TVR to but sadly had to sell it.
Here's an example of his Capri.

later 24v "BOB" code engine makes 240hp bog std on std injection. Take off the airflow meter and run it on megasquirt and its good for circa
270hp, these are EXTREMELY good engines, just a bit heavy.
On a simpler note, the 2.9 on paper is worth nothing over the 2.8, but it has bags more torque in reality (I've owned plenty of both in numerous
cars! ) and due to the sensible number of exhaust ports on the 2.9, it responds to tuning.
Look at a eurocar racer engine, they make 240hp from the old 2.9 on a single downdraft carb with a cam and mild head work.
never the worlds greatest engine but actually far better in practice than on paper! They also go on for ever as long as you don't go over 7000
rpm
I've got an overbored 2.8 in the shed. It came out of my mate's Cobra and was nice and quick with just a twin choke Weber and decent headers. A fast road cam also helps.
