Could this be made to fit, at a price

A bit out of my budget !  I have a spent a fair bit on the conversion and associated stuff (in steps) so I don't think I'll get away with that one without wifey noticing !!

Are the multirams driven by the ecu. I noticed the one on the back has a two pin connector. Unfortunantly other  than that one, I don't think I've got any other bits of the ram setup ?

[Doctor Gollum]

The mechanism is basically the same for both, and yes, it's run by the ecu

[MikeyBikey]

Morning all, hope you are all well.

The car / conversion is running incredibly well. The engine is still pretty much standard apart from K&N filter and three branch manifolds. Runs on lpg all the time but I do have a petrol backup. So two tanks, fuel lines, sets of injectors etc. Switchover is by a single switch on the dash and is pretty seramless.

As you all have noticed LPG is getting problematic, so ive put on a 90L lpg tank to help keep average distances between fillups decent.

Do anything from 50 miles a week to 700 miles a week, regularly, depending on visiting family or attending track days etc.

Anyways finally had a rolling road session last week so managed to get 240bhp running on lpg and a pretty sensible tune, so i can cruise around town easily as well as race when need be. (Car weighs 1200kg with me in it)

Still thinking about engine mods !

still thinking about buying some 2.5 heads , porting them etc. But might be a lot of work. Not even sure if they'd fit.  Will keep you posted.

CNC Heads offer off the shelf ported heads for VX V6, https://www.cncheads.co.uk/vauxhall/vauxhall-vectra-3-2/
Might save a lot of experimentation.

Thank you.


After a lot of use, approx 15000 miles year , extremely hard treatment doing track days, drag racing, donuts and burns outs  I can confidently say the engine is epic. It is still completely standard, late 3.2 albeit with 3 into 1 headers and lpg conversion. I have however literally just got my hands on a set on 2.5 heads  so I might try this. Thank for the link.

On a different tack I have gotten through two 5 speed manual gearboxes. Both have failed on selecting reverse. I have just fitted a third and its completely rubbish. Sold to me in good faith, refund offered however its in situ and a PITA to swap. I'm going to gee if I can get one of them rebuilt, goes to the Falmouth gearbox centre tomorrow.

Just after some advice please.
I have two 5 speed gearboxes that bolt onto the back of my 3.2.  Both broken. I understand both came off police cars.
As in I bought a broken police car, and took the gearbox / engine from it. The other gearbox I've been told by the seller Lozzz,  came from a police car. (lozzz from this forum who also did a omega V6 conversion into a scimitar and a good friend,

Both my broken gearboxes say R25-R28
on the casting there are some numbers stamped in the case
HP 116 02A
1529698

and
GL 136 00B
1480203

Both have a fifth gear ratio of 4 revolutions on the input shaft equates to three revolutions on the output shaft. I'll double check this to get it exactly.

Do any of the stamped number help me to identify exactly the box.

Does anyone know of any spares , eg bearings, that I  can get hold of. (Lozzz also has a noisy gearbox  )

cheers y'all

I wasn't exactly nice to my car, also ex plod, but that was still on its original gearbox well past 250k.

If you keep blowing up gearboxes, then you need a better gearbox, because it sounds like the R25/R28  isn't suitable.

[MikeyBikey]

yes 

I have investigated

the ZF 8HP. Used prolifically by loads of car manufacturers, virtually indestructible, but needs an ecu controller costing in the region £2k. (After purchase of box, adaptor plate etc.) So probably £2500 min. 

Nissan 350Z - Cd009. Currently rare, very desirable by engine swappers and costing min £1800 plus adaptor plate etc. (later one is the one, earlier one has synchro problems) so again into £2k.

I'm curious how he got them to fail selecting reverse

J turns and poor clutch timing?

My '03 car with total plod history got dropped to 2nd instead of 4th mid pursuit as it was accelerating though 120+. This blew the engine. New engine got bolted to the original box and put back into service. The box is pretty durable, but doesn't respond well to quick shifting... it needs a moment to keep up between changes. One reason why it's considered clunky.

[MikeyBikey]

I do change gear quickly when on track etc. I have watched videos of others who manage to change smoothly , but I'm always in a bleddy hurry.

Have you considered something from the JLR stable? Specifically Getrag 221 5 speeder or the ZF S6-53 6  speeder? Both fitted to S-type jags. The former to the 3.0 V6 and the latter to the 2.7d. The 6 speeder is extremely hardy and is used in manual swapped 4.2 super charged v8s.

The Getrag is less hardy, but in its normal home it's mated to the Jag V6 which has both more power and torque than the 3.2 so it should last unless you're very ham fisted 

Neither is a bolt up solution, but seeing as you considered a ZF 8 speed, I'm guessing that's not your main concern.

 I have an R28 from a Carlton/Senator for sale

If you were going to scrap it anyways...
