Discussion
Right, the 400SE has been sitting idle (started every few weeks, and battery always charged) in the garage for almost 2 years now. The problem is as follows ..
Car Engine spec was never confirmed (the car should have had stage3 heads, cross bolting, billet crank)
Anyway, The time has come to get the car back on the road.
I was thinking of replacing the injectors with new (no reason other than they are the origional ones, and are probably a bit in-efficient.
Following this, A service on the engine, checking all tolerences, then getting the car re-mapped on a rolling road, to have the fuel setup correctly.
I was looking at replacing the plenum and trumpets with Carbon ones, but cannot justify the the expenditure against the performance gain given the fact the car isnt raced or anything
Anyone recommend a good tuners ?

Hi Jason, I met up with some guys from Austec Racing in Crawley, West Sussex who were running their own Griff and Tamora at a TVR meeting at Santa Pod earleir this year, and they were really 'on the money'. They seem to understand the modifcation limits of V8s, and they have worked on my cars in the past. Give them a try - call Paul Austin.
I'd just bung a can of injector cleaner in the tank and leave the origainl injectors in place, unles you've got the later fuel rail they're difficult to source in any case.
As for tuning you might want to try this first for a cheap option

I've fitted Bosche pink tops - bought in the States are the exchange rate is very good.
They are a much more modern replacement for the ageing Lucas injectors.
They produce a much better spray pattern and feel really smooth
to drive .. they have made my car run richer lower down - so I guess they are flowing more fuel - so re-mapping would be necessary.

Do you have a part number for them? As I 've got a list of the old bish bash stuff and can hopefully tell you the flow rate the std rover ones are 196cc/min @ 2.5 Bar with the 'jag ' one at 236 cc / min
As yours is quite a late car though does it have the o-ring seal at the tops of the injecotrs or the comedy rover jubilee clip arrangement?

Matt - my injectors have o rings top and bottom.
They are 22lbs - so around 231cc / hr.

19lbs does work out to 200cc / min which is exactly right.. but that would mean your max bhp would be around 258 unless you changed the pressure (read - re-mapp..)..
22lbs works out at 300bhp at 85% injector duty cycle.

I used fivomotorsport for my first set of injectors, no problems with them.

Yours is the later fuel rail then which uses a 'normal' bish bash injector the earlier wedges used a injectors with pieces of rubber hose swaged onto the back of them
which then leaks every now and then....

Yes - I saw it first hand a few weeks ago .. FrenchMike had the plenum off at Boulogne on route to Le Mans .. leaking fuel injector pipe(s?) ..
I suggested he use any spare fuel hose from the supply / return pipes .. but he might have already thought of it.
