Sway bars / antiroll bars
I've got the whiteline ones on mine. Got to learn to drive the car all over again, but do make a big improvement.

advantage of dropping compression ratio??
No, at the bottom end you loose torque/power as you're still at the same boost (or vacuum) levels generally. At higher rpm you can run more boost so make more power/torque. It is a trade off though. On a road car, best stick to smallish turbos and relatively low boost levels + highish CR to keep it driveable.

It just means you can run higher boost safely.

Mainly, CR and octane dictate the boost you can run safely (as long as you're in the efficient region of your tubs). Dropping the CR allows you to run higher boost. You're right though, you loose power at the same boost level (or off boost). Really low CR, laggy turbo cars are hideous.

SWB, exhaust, how different from LWB
Leon made my single exit (SWB), and again it's incredible. One of the few people these days who takes genuine pride in his work.

T-28 turbo's
Yeah, you'll max out your injectors. If you don't want to shell out on injectors you can try an adjustable FPR to get a bit more, but the only way to know for sure is get it hooked up to a wideband and check (I have one). SAFC is a crude and horrible way to tune. It makes no allowance for load, and the corrections you need at full throttle will be nothing like you need at low load for the same RPM. They also mess up the timing.

Happy Birthday TonyC
Happy birthday mate, hope it's a good one.

Hks 2530 Kit Help!!!
If it's a 2530 and not GT2530 then they're non BB turbos, so more laggy than the GT2530. Depends if you want to live with that really.

What was your 1st ever car????
205Gti 1.9 still miss it sometimes :(

removing abs
TCS only uses the ABS sensors, no reason it should need the ABS system its self - would need to try it and see just to make sure, but I'm pretty sure the wheel sensors are just inductive and don't need powered externally.

More O2 sensor woes
Mike Feeny (MJP in the traders section sells them) they're cheap. Think it's 32mm from memory

Titanium Pipe
Leon at Alunox uses it to build exhausts so he can get you some (01978366774). It's £££ though!

Intercooler hard pipe options?
Leon at Alunox does some 01978366774

the zs gone
Must say Greg, didn't really notice until we left Ztech the other day, but your's is one of the nicest Z's I've seen. Just kinda subtle
-
Checking timing
Doh! You must have beat me by a few seconds.
-
Checking timing
The best way is to buy a single HT lead, then run that between No1 plug and coil pack. Clamp the gun on there.

A BIG thank you to John Dixon
No probs Paul, pleased we got it all done.

FAO John Dixon
It's sold, cheers

Happy Birthday JD!
As long as too much Jack Daniels doesn't do it I'll be fine! :dance: Cheerz everyone

ecu self learning
When it's running at low load / speed and target AFR is >14.7:1 (leaner than stoichiometric) then the ECU compares the actual AFR as read from the lambda sensor with the target. To correct the difference, it calculates a correction factor which it then adds to all injector pulses across the entire fuel map. Not entirely sure about how the calc is performed, but it's likely to be an incremental thing that is modified on each pass over a site.

Happy Birthday JD!
Cheers guys. The old 30 just keeps creeping up !!

next step???
Wouldn't bother with the SAFC either, waste of time and nothing that can't be done with proper mapping. As Jock says, best really to concentrate on brakes & suspension before doing much to up the power, it'll be a far better car. I'd look at poly bushes, rose jointed tie arms and shocks / springs at least.

Bypassing the power steering pump after removing HICAS???
The relief valve may be part of the under bonnet solenoid assy. You could possibly blank the 2 lines running to the back of the car if so, but then you'd still be using more energy than just looping it if it's going through a PRV
-
Bypassing the power steering pump after removing HICAS???
If you still have a supply to the pump, then don't just cap it. It will most likely blow the cap off, these pumps produce a resonable pressure as they're positive displacement types. You could just loop the feed / return on the pump together with a short piece of pipe, or remove the veins.
-
Bypassing the power steering pump after removing HICAS???
There's 2 options: 1) Remove the veins from the rear pump impeller then blank all lines. 2) Take the high pressure return from the rear pump chamber and plumb it straight back into the tank (into the spare 10mm spigot) Or as Jock says, use an NA pump, but you'll need all the brackets etc. too (I did this on mine)
