508PN Questions
How much does a replacement 508PN engine cost, fitted?
Fitted at our workshop, a low-mileage used 508PN typically runs £1,000–£2,500, a reconditioned unit £2,500–£5,000, and a full rebuild of your own engine £2,000–£5,000. The exact figure depends on the variant and what the strip-down reveals. All our prices include VAT (GB 502 3788 04). Enter your reg above for a fixed written quote.
Do you supply the 508PN on its own?
No. Every engine we supply is fitted by us, at our own workshop in Grays, Essex. That is deliberate: one party is then responsible for both the engine and the fitting, which is what makes the warranty worth having. If you cannot get to us, we can collect your vehicle and deliver it back.
What warranty comes with a 508PN?
12 months or 12,000 miles, whichever comes first — parts and labour, in writing. Servicing can be done by us or by any established professional garage; you are not required to come back to us.
What's the difference between the 508PN and 508PS?
The 508PS is supercharged; the 508PN is naturally aspirated. Same family, different induction — we'll confirm which you have from your reg.
Do you replace the timing chains?
Yes — new chains, guides and tensioners as standard, addressing the 5.0 V8's known fault.
What a Fitted 508PN Includes
Every 508PN we supply is fitted by us at our Grays, Essex workshop — never sold loose. Your price covers the whole job:
- The engine — reconditioned, tested low-mileage used, or your own unit rebuilt, matched to your exact variant
- Removal & fitting — the old engine out, the replacement in, by JLR specialists
- Fluids, filters & adaptation — the parts and coding the job actually needs, not billed as extras
- A documented road test — before the car comes back to you
- 12 months / 12,000 miles, parts & labour — one warranty covering the engine and the workmanship
Turnaround depends on the engine — see the lead times in the options above. VAT is included in every price.
Not local to Essex? It makes no difference to the engine or the warranty. We collect your vehicle, fit the 508PN here, and return it — wherever you are in the UK. Here's how nationwide collection & delivery works.
