Good day, I Sorry I do not own a British sports car but do recall helping my Father restore an MGB for a customer decades ago, and I'm sure it's still showing today.  I mostly joined to gain and share knowledge of the 215 V8.  I have and Oldsmobile Jetfire version of the 215 motor my dad acquired back in the 70's sans turbo system. We ran it in stock form with 2bbl heads in a jet boat back in the 80's till the heads cracked during a tough Michigan winter.  Fast forward a few decades and my Dad and I decided to rebuild the motor using original high compression heads so we can fit it into 1990 Miata.  Thanks for having me,

Richard

Welcome, Richard!

I always thought that the Buick/Olds/Rover V8 made the most sense for a Miata.  Years ago, I ran across a website that detailed a Rover 4.6L swap into a Miata.  I do hope he finished it.

Please start a Project Journal on this site so that we can follow along.

What a great website! My first modified British sportscar was a Mk2 Sprite that I fitted a "B" series motor to.That was in the early 70s.I then produced a transverse mid-engine (RoverV8 mated to BMC 1800 gearbox) kitcar that earned me enough money to go to England in the 80s where I worked initially on kitcars but led to work in UK and Scandinavia on Group B Rallycross (Ford RS200 and Quattro S1). back home in NZ I made a mid-engine 4WD hillclimb car using the last of my kitcar bodyshells.That car went on to win over 30 hillclimbs and rallysprints. Other builds include replica 1998 Porsche GT1, replica 1938 Alfa Romeo 8C2900, spaceframe Speedway racecar,a couple of original motorcycles,my current racecar which is a spaceframe , carbonfibre body Jag XK120 powered by quadturbo V12, under construction is a replica Broadspeed XJC and replica Alfa Romeo T33 Stradale.My daily driver is a 1955 DeSoto pickup truck powered by....TaDaaaaaa...ROVER V8! I am slowly working on my Triumph GT6 with 2.5 P.I. engine
Numerous other projects/builds along the way

Good morning, I live in southern Kentucky and have owned numerous British cars in my liftime. Today I own a '80 MGB LE rust free project for sale, Am building a 5.0 ford v8 in a '71 MGB GT, A '60 Morris Minor 1000 convertible and I am waiting on a '70 Morris Minor Traveler being shipped from England hopefully this Thursday.    Love this site,

Hello,
I am (Forrest) Lee Erickson
I have a 1972 MGB on which, when I was younger and more flexable, I started trying to fit a small block Chevy into the engine bay but stalled.  I am no longer working and considering restarting the conversion and willing to consider other engines. I would like advise on what might be emerging as a standard recipe.

I see some 3.4 V6 conversions about which I would like to learn more.

Will try to post photos some time soon.

Forest,
Please study this link:

Hi, just thought I'd drop a few lines here.  I have a 74 Triumph TR6 that I specifically bought for a V8 conversion.  It'll be all aluminum from the LS family of engines.  Transmission will be an AR5 manual using a Fabbot adapter kit.  Rear diff from a Nissan Z350.
I am going to try to lose the flexy flyer chassis behavior and put some effort into strengthening and stiffening.
I will likely be in touch with some of you who have been where I am now for some details.  Thank you in advance for your help!

Howdy! I'm from the MGEXP forum.

Doing a Buick 300 swap in a 79 MGB LE (In the US some 79's -were- in fact true limited editions due to import laws)

Here and there for all the expert advice all ya'll have hoarded over the years!

I am (Forrest) Lee Erickson. Currently 64 years old and getting stiffer and stiffer.

I have a 1972 MGB Roadster, wire wheels.
I would like to finish a conversion to V8 or V6.  
I started in 1984 with a SMC (283) as a proof of concept that did not look like success.
I live in Maryville TN not to far from Towensend where there is an annual British Car get together I have from time to time attended.

I have concluded that if I am to succeed I need to start with a more modern donor car but do not know much about cars after 1970s technology.

I have also concluded that I had best purchase more than fabricate as I am feeling less and less able and want to enjoy a drive in the car before I can no longer climb down into it and up out of it.

Hello all,

I'm Erik. I have owned my 1971 TR-6 since 1998. About a year ago I decide to RestoMod it.

Instead of going V8, we have put a Honda JDM K24A with a Haltech Elite 1500 ECU in it. Custom headers. With almost no ECU tweaking we anticipate around 225+ HP. But one of the reasons of going with the K24 is it is super tunable. Even without forced induction we can probably get nearly 300 HP. And if we decide we need more power, there are a lot of bolt on turbo and supercharger kits for that engine. The transmission is a 6 speed out of a Mazda RX-8. The differential is an R200B out of a 350Z. We did the CV rear axle swap. Wilwood brakes. Gas shock conversion. All poly bushings.

The goal here was to greatly increase the HP, AND lose a bunch of weight. Another goal was to make the car look entirely stock. We're anticipating the car ending up around under 2000 pounds.

We anticipate being on the road by August. Right now we're doing engine bay cosmetics and reassembling.  MotoResto in Portland Maine has been doing the work. I attached a photo from a few hundred hours of work ago when we were still mocking up.

Welcome to the forum Erik.
I have often thought that the K20 or K24 would be an excellent swap for any old British sportscar.
In my opinion going this route is quite easy with lots of upside without having to butcher the firewall and extensive frame modifications.
I put a 2003 GM 300 v6 in my 76 TR6 with a T5 transmission and a Nissan R200 diff.  Mine also is stock looking in the interior and exterior.
My car still sounds like a six.  The only downside of your swap is the sound of a 4 cylinder; but who cares when you can have 300hp!
Keep us posted with lots of photos.

hi everyone,
1971 TR6 owner here with a restoration or a resto-mod planned within the next 2 years.  It's all up in the air at the moment - rebuild the 2.5 6 pot lump, maybe cut the head and use a bumpy cam or maybe do an engine swap.

For swaps, I've entertained the idea of a Mopar 3.6L Pentastar.  There's a forum for Mopar enthusiasts that has used the Bell Housing from the A580 Mercedes Auto and a fabricated adapter plate to connect to a Tremec T5 manual - the transmission ends up canted 5 degrees off of vertical.

Or, a Ford 5.0 which would go nicely with a T5.

Or, maybe figure a means to adapt a T5 to the Triumph engine with a new fabricated Rear Engine Plate and a Bellhousing from a pre-93 Mustang 3.8L T5 Bellhousing.

Lots of peeps here have explored these options (except maybe for the Pentastar) so I'll be mainly going through a lot of forums and occasionally asking a few questions here and there.

Thanks in all your postings and the obvious enthusiasm for doing hot-rod LBCs

Matt,
Wrlcome to the insanity.  Check with Don Watson.  He's done the Ford swap.

Hi Everyone,
I used to autocross and open track my modified Triumph TR-6 in northern Illinois. Then I spent some years playing with Mustangs. Now I live in Key West, FL and recently purchased one of my dream cars. A Rotus Eight. It needs a bit of attention, as most old cars do, but I love it.

Tom,
Welcome! That looks like a lot of fun!!
Phil

OK on Jim B's say so over on the MG Engine Swaps Forum, I've finally gotten around to joining here and putting a little $ in the pot.  I have a 60 Bugeye that my Dad bought in 1967.  I drove it my senior year of high school in '72 and have kept it ever since.  It now has a GM 3.4L V6 and drive train and chassis mods to handle that.
    So there's a story that could be told.  But not in the next few weeks though.  I'm currently converting it from the Holley 390 4bbl to Holley Sniper2 FI and I need to finish that and get some test driving in before the weather here in western NY goes bad.  A more lengthy post and/or photo submissions could be in November or so.  This is a pretty large site, so if someone has a suggestion on where/how I should start, let me know.
    FWIW, the street photo here is a current one from this past August.  And a piece of photo art, with yet another story behind that.

Welcome, John!! Can't wait to hear your stories!

Scott

Excellent! That's an attractive car. I almost bought one when I was in my early 20's but ended up with a Landcruiser instead that someone had stuck a SBC in (badly I might add). Not sure which would have been the better life decision but that hardly matters now.

Start a thread in the forum of your choice and post away. Sounds like an interesting story.

Jim

The carb to EFI should be in engine, trans, drivetrain section.  The stories, post here in the BritishV8 Pub for all to enjoy.

Ive been reading and lurking for a while so its probably time i introduced myself. Im Chris from the UK and I have recently started a non V8 engine swap into a 1979 MGB GT.

Ok when I say non V8, no its not even a V6, just a 1.8 liter 4 pot Miata engine and 5 speed transmission going into it.
Despite my advanced age this my first proper engine swap into a production classic car and my criteria included using as much as I can from a single donor car which can stick around until its picked clean of anything useful and I have parted out all the less useful stuff.

Thats probably enough about that for now as 1. I will be starting a build journal and 2. not only is it a 4 pot, Miata/ MX5 swaps into a MGB have been done before so unlikely to break much new ground.

Ive fixed, modified and played with cars for decades though. Probably the most interesting thing was having built a replica AC Ace back in the day: This was based on a Hawk replica 289 Cobra chassis, ran a stage 2 modified Triumph TR6 straight six & OD gearbox, MGB rear axle and part MGB front suspension. It looked and drove well in BRG with spoke wheels. 
I often wished Id kept it but I needed the money towards a house at the time   

Love you AC Ace.

Good to see you here Chris, have you met Steve Pegrum? He lives at Brentwood and is currently rebuilding a Gilbern Invader with a Jaguar AJV6 engine and a Dutton.

Welcome to the forum!  I'm looking forward to your build thread!

Scott

Thanks guys.  No, Ive not made contact with Steve Pegrum as yet Philip. I'll look out for his build thread.

I have tried to get him to do a build journal here but he is too concerned that his paint job isn't up to scratch. His last email to me contained the following "Essex Kit and Classic Car Club) has a monthly (last sunday of the month) Breakfast meetup at a garden centre off the A127". I thought you might have met him there. You can see his YouTube videos if you search "Invader Garage".
