Major Horsepower increase...
Discussion
As far as I can see, to bump up the horses of my chimp, I have 2 straightforward ways.
Supercharger - 5K.
Engine swap (to 5 litre from 4) - unknown.
It's currently a 4 litre, with Nirtrons and proper brakes, and the power is getting a bit boring, hence the post. So, do people know how much an engine swap is, and are there any other ways of getting a lot more power?
Cheers!

It depends on how much power you want, and what state the 4ltrs in at the moment.
a refresh and some head work a cam and a rechip on the 4ltr would make a difference, as the 4ltr isnt that highly tuned.
Swapping the ECU for something programmable will allow you to do mods as and when, and mappable ignition can make a big difference.
a basic 4ltr only puts out about 160-180 bhp at the rear wheels or 200-220 at the flywheel..
Jamie at Castle Race Engines did some good things with ours when we ran a 4ltr in the Tuscan Racer..

The real reality is not how much power you want but how deep are your pockets, its pointless saying you will be happy with 275 if you have £10000 to spend, on the same asumption if you only have £2000 to spend it wont happen, whoever will carry the work out even your self make a budget and see where your pound is best spent.

Hi Rob.
the TVR Power S/chanrger upgrade is 4500.00 plus vat. What upgrades would you suggest for the same money on an otherwise std TVR 4 litre engine and how would it compare to s/charging in on-road performance terms? cheers, joo.
Good question Joolz, I look forward to Robs reply.the TVR Power S/chanrger upgrade is 4500.00 plus vat. What upgrades would you suggest for the same money on an otherwise std TVR 4 litre engine and how would it compare to s/charging in on-road performance terms? cheers, joo.

How much would you get for a good 4litre motor? How much are Robs 5.3-5.5 motors fully installed. I guess it'd still be a fair bit more than the charged 4litre option. Rob, options?
I have tried to sell a 4.0 TVR engine on ebay, it struggled to £600. The big motors make good money, but the Range Rover motor aint worth alot, because thats all it is. I bought an LSx motor, with some tasty internals and stretched to 6.3 for £3k, and thats around 500bhp. That takes some beating on the bang per buck equation. Even a cammed standard one (5.7) is around 420+ bhp. and they can be bought for around the £2k mark.
Pound per bhp you cant beat that price if they are making 275 at the wheels, our stg 3 4.6 is going to be the closet but that will still be more money, around £6k fitted and making around 280 at the flywheel, for £3k you could have stg3 heads/cam/induction mods/chip/rockers all fitted and this would be making around 260 flywheel, the big motors can be a lot more money depending really on what you have on top ie act carbon gear/ after market ecu's etc... the one joolz mapped for me cost just under £10k but he did have his old 5ltr to sell on, so at least he got a bit more back for that, a second hand 4 ltr would make around the £800
I must admit the price you can pick ls1's up for now is silly for what you are getting, funny enough a friend came to see me today from aus and they are going out there for less than £500!! ls6's for around £1000 and ls2's for around £1800, christ it was only 12 months ago you would be happy to pay £4k for an ls1, i dont know i guess it is probably the ls7 they have brought out that has dropped the price of the others?
Don't be fooled into thinking they're all that cheap though. A dogs a dog and there are plenty of those around now they've racked up big miles. A lot of people who can't diy will get big bills for the rest of the stuff needed to do a conversion. Making the initial plunge can be expensive, once that's done it's not so bad.

Do you know of anywhere reliable to get a complete engine and trans (wiring, ecu etc) from Mike?
There are one or 2 firms in the US specialising in F body pullouts so you could give them ago. There would be a 3 month warranty but you lose half of that in transit and anyway, would you send it back if you had a problem?Boosted.
boosted, if you wanted to race an ls 1/6 in place of an RV8, are the stock parts up to it? or are their any major failings. I'd dry sump for piece of mind, and be looking to use your internal crank trigger wheel, probably your water pump housing with an electric pump, loose the pas pump and probably the alternator as well.
what sort of power would you be looking at stock?
cheers
