one other go faster trick - change out the geriatric auto gearbox and add a pedal

[T.m.f]

If you could drive a manual,try a renault 5/11 1.4 turbo,if you could find 1,from personal experience my 11 was very quick at pulled upto 135mph  very quickly on my personal test track.

Change the differential to a higher ratio.

My MV6 will be undergoing that improvement soon.

Since my car has been off the road since last November I've made a few enhancements, but still building up the engine so can't say for sure how much better it will go -

Extensively gas flowed and ported heads
3.2 ported exhaust manifolds
Ported plenum and lower divider
Jetex 200 cell sport cats
Jetex full stainless exhaust system
2.6 auto differential 4.22:1

This will complement the already in place -

Superchips custom map
Piper fast road cams
Drilled airbox with K&N panel filter

Theres a few ideas for you!

Ive suggested modifications to you before, you were considering a 3.2 engine? Or a chip?  These ideas seem to have gone out of the window so to speak have they?

A nice cheap mod is the differential

Cheers Dean

Make the car lighter. And the driver

[Webby the Bear]

Spirits thanks for that. I've considered a diff replacement but the increase in idle speed would annoy me. And currently waiting to hear about a good priced remap.

How did you go about porting the plenum out of interest

Big griffin it's a good point you make. I'm eighteen stone lol couple of the the there I reckon

Cylinder head developments did the porting and gas flowing, along with 3 angle valve sears and skim to clean the head.

Interesting mate.  I may have a word with the chap from cylinder head services who we usually send heads to for skimming

Webby, I (briefly) had a 2.5 with 3l cams and Superchipped.  It still wasn't a patch on my 3.0, not even in the same league.

I would start with a better engine, before considering *any* mods.
