Sensor location decides how well your ECU reads the engine.
Sensor location decides how well your ECU reads the engine. Coolant temp in the head, IAT in the intake tract, wideband b**g in the primary. Each one placed where it sees actual conditions rather than a lagged average. That decision, made before the engine goes in, is worth more than an extra hour on the dyno.

Small block or big block: which one did you build around?
Small block or big block: which one did you build around? Weight, parts availability, and rev range versus cubic inches and raw torque. Drop your engine choice in the comments.

Not your local city centre spec.
Turbo car spec.

AEM Water M**h kits in stock now for people who like boost but would quite like to keep their pistons where the factory originally put them.

A solid bit of kit if you’re pushing on, running things hot, or building the sort of car that makes sensible people shake their heads.

Get your fix here.

Puma Defender owners, I am about to spoil your life.

Because once you’ve driven an LS3 + 6L80 swap, a stock Defender feels like it’s towing its own sadness.

These photos are from and this is exactly the standard you want to see. Clean bay, proper packaging, the sort of install that looks like it belongs there. They rebuild LS3s and do complete installs, and we supply various parts to support these conversions and make sure they actually work as a system, not a pile of receipts.

If you want your Defender to start, idle, pull, cruise, and behave like a modern vehicle, this is the move.

Comment LS3 with 90 or 110 and we’ll point you at the right kit route.

If you want it built turnkey, speak to DT Engineering.

Want the link? Type DEFENDER and we’ll drop it.

Your project doesn’t need “another winter of plans”.
It needs an engine.

Crate power is the shortcut that still counts: new, known spec, and ready to turn fuel into s.p.g (Smiles Per Gallon).
LS, LT, LSX, Ford and more, available now.

Tell us your chassis & target power and we’ll recommend a combo.

More boost is easy. Keeping it happy is the skill.

AEM water/meth kits help control intake temps and give you more breathing room when the map gets spicy.
Official UK stockist, on the site now.

Tell us petrol vs Ethanol, boost level, and if you want a basic or failsafe-heavy setup.

Big boost requires strong nuts.
ARP understood the assignment.

Studs, bolts, hardware that stays tight when everything else is trying to leave the engine bay.

We sell the stuff you buy right after you say, “It’ll be fine… I’ll just run it on the stock ECU.”

Haltech gives you control, logging, safety strategies, and tuning headroom for when the build evolves (because it always does). ECUs, sensors, looms. It’s all here.

Need help speccing it? Drop your engine, trigger type, and what you’re trying to run.

That moment when boost comes in and your clutch turns into a smoke machine.

Choose your stage, fit it once, drive it like you mean it.

In stock, UK supply, on the site.

Comment your car + power and we’ll point you at the right kit.
