The V6 I got was overheating as the head-gaskets were shot.
So while the heads were off I did a bit of DIY porting, nothing spectacular but hopefully it's helped things along a bit.
Apart from a DIY exhaust with Powerflow back box and a cone filter it's bog stock.
The car's stripped and on coilovers with Tubby front brakes, that's it.
Here's my build thread over on the PPC forum-

To be in with a shout of winning you really need a car capable of a 14sec 1/4mile or better, and nimble for the handling course
(MK1 would be ideal!!
)
And as if by magic, here's one with a goosed engine

Still some easy tuning for you still.
I would suggest if you've not played with the AFM or timing you can get at least another 10hp there for free.
I have back-to-back dyno'd and got around 20hp from this
(155whp to 17*whp), still with safe AFR's.
And if possible get rid of the toyota exhaust merge if you have not already.
My mk1 currently runs 13.3's, with a little tuning
(ported heads and a little too much timing).
Still has factory y-pipe
(horrid design and going asap).
AFM tuning was conservative, never leaner than mid 12 AFR's.
Last dyno's said 165whp, I expect to easily surpass 200whp when I've got rid of the toyota cast manifolds and y-pipe.
Should be enough to get mid 12's.
And 11's with either of the M90 superchargers I have.
A friend has a rev3 tintop mk2v6 that has 205whp, that does 14.1 1/4mile runs, not spent much on tuning the engine
(no porting or forced induction).
Nice goosed mk1, unfortunately Horsham is a longway from yorkshire and it would be a shame to track prep such a mint looking mk1.
