Here's one in an MGB:

Fookin ell.........that should have some pull.

Far quicker than an MGC or MGB V8, I imagine.

60hp more than an MGC(and a lot lighter), about 80hp more than a stock V8 MGB and 20hp more than a stock 3.9 EFI Rover.


It's gone in without cutting the car, so it's completely legal and the 4cylinder diff ratio doesn't need changing unlike a Rover swap. Worst bit of the job is the exhaust manifolds.


It ought to go well and make a nice cruiser.

So she's in and running.  At lot of phaffing with the fuel map as she's soo rich.


So did a fair bit of research and investigated the fueeling... NOT.
Had an idea on the way home. Just took 4 values off every cell in the fuel map and went for a drive.

Still overfuelling horribly at the lower rev range & under load but once she shakes the misfire off she just launches her self at the horizon like a rabid rottweiller on steroids who's seen a bunny rabbit 2 miles away.

FM. Scared meself silly. Wheelspinning, having to change gear like a loony cause she's spinning up so fast then hitting the powerband and being pushed back in the seat. Honest I was glad to shut the garage door and walk away for a beer and a lie down. I'm sure I could hear her barking as I walked away... Probably saw a cat on the horizon....





I had posted some google links to pictures but its trying to log in as me

looks like a nice conversion, although I reckon theres space for another one in front. That would be proper quick.

looking forward to pictures

looks like great fun 

[MikeyBikey]

Thank you dave, how did you do that?

The sprinting pictures were with the essex 3.0 fitted and 150 bhp. Now I've got the y32se I'll have to grow some...

Thank you dave, how did you do that?

if you click quote on my post with the pictures, you'll see the text 

anyway, fantastic project
I'm from Tamworth originally and have a soft spot for all things Reliant 
keep us posted on progress

A very tidy installation, and a great use of a Y32SE.  I hope you sort the mapping and driveability issues, so you can enjoy it without scaring yourself!

[MikeyBikey]

Hi All, apols been a while since an update. Its been an odd year with a couple of attempts to move house being thwarted and a family relocation so this has been a project run in parallel to life at the mo.

What hasn't helped is a lot of teething problems with the drivetrain. And then once it was sorted  I've destroyed the engine, i think. So i'm after some pointers re these engines, what can go wrong etc please.

After a recent reinstallation of gearbox / clutch went for a spin. Parked up at Asda, some odd noises from clutch / gearbox region. Came out of the shop, the engine sort of started then died withmore unnattractive noises. Had to get towed home. After a lot of investigation (mostly on drivetrain !) I did a compression check.

Cylinder 1 - 50psi
Cylinder 2 - 0
Cylinder 3 - 0
Cylinder 4 - 0
Cylinder 5 - 50
Cylinder 6 - 250 psi (yes 250)

Cam belt good (new last year, tensioners good. Cams all good. not snapped etc.
Oil clean, no water loss.

Its out now and gone to the engine man but its frustrating. It was a low mileage engine  . I have a spare but with 167000 miles)

So any ideas what might cause that sort of failure ?


(PS the drivetrain issues turned out to be the flywheel not being true . This is now resolved)

cheers

Is valve timing correct?, these engines are tough as nails  and can take a thrashing,all the police forces who used them will testify to that. I personally wouldn't spend much on the busted one,just fit the spare you have and hope you have better luck (167k should have plenty left in it)

[Doctor Gollum]

Agreed, short of the belt snapping at speed, they'll easily run to 300k+ with nothing more than 10k oil changes and 80k belt changes 

Also, new engines were less than £2k from VX, so don't go spending too much on a rebuild

[MikeyBikey]

Ok thanks, hopefully the engine man finds out the cause, just don’t want to repeat 

[MikeyBikey]

Question re cams. The y32 that’s failed has all four cams giving the same lift, 10mm. Is that normal spec?

[Marks DTM Calib]

10.2mm from memory, its at this lift that the curtain area is equal to the port area so optimum.

Did the engine over speed when the clutch let go as that's classic timing jumped and bent valve symptoms?
