It's obvious that with enough money it's do-able!
It's a case of you making the car the best you want it to be.

I'm in Essex and when it happens I'd love to see it.

I've always wanted a street sleeper, seen a 75 v8 with the supercharger
I think my 924 is more realistic between the two...want to turbo charge it, need to find the right way and the right people!

Wish you all the best in making it happen

I remember missing driving so much after I had a bit of hand surgery. Boxing injury resulted in two bones slowly pushing themselves out of place.

If it all goes ahead I'd certainly not be shy at showing it off so I wouldn't worry about not seeing it hehe.

Thanks for the support!

Go for it the cosworth engines of the 80s and early 90s were 2.0litre and pushing out 600bhp+ so a 1.8 making 300bhp is easily doable and when you look into bike engines some of the Hayabusa's make over 300bhp without breaking a sweat using standard internals and are 1300cc with a supercharger or turbo plumbed in, Jack Frost at Holeshot racing has made mega power with these engines 700bhp+. I think cooling would be your only problem as these K series engines have a bit of an issue though the Lotus boys dont seem to have so much of an issue from what I understand,

been in this position with my old sierra cossy but like you i suspect i did it got it to 330 bhp at the wheels proven on rolling road then after a while got fed up with idiots trying to race me off the lights etc but one thing i can say is i did it and enjoyed every second of driving the beast good luck and keep us informed

That's not a rhetorical question... any people in the know that know?
Suspension is mostly based on the car's weight and the stiffness required. Engine power is largely irrelevant to suspension.

On the V8 the front wishbones and the rear trailing arm are the same as on a normal ZT.

I would suspect that parts that take the additional power need to be looked at.

I would thing that from a suspension set-up you'd be alright.
However I would look at the torque the drive-shafts and the CV-joints can take.

Good luck with this

As said look at diesel parts for the torque issues, I have driven most turbo rovers and the zt I feel would not stress at all running 300bhp,

As a note the pg1 gearbox as uses in the rover 2.0turbo cars is not all that strong in standard trim due to poor bearings, the zt box is built alot stronger so I can't really see a issue and you don't see many zt boxes fail.

My thoughts were that 300bhp wasn't too ambitious. It's quite a sensible target for the budget I'm looking to play with.
Cooling is certainly something I need to look into - Like you say, the Lotus guys seem to have it figured out so I will check out their builds.

It's just a why not kinda build. Be good to take an engine that a lot of people have doubts about and make it into something fairly special.
The more people that do it, the more manufacturers might start making bits for our motors.

Drive shafts and CV joints seems like a sensible place to start. I didn't know that the wishbones and arms were the same so thats quite helpful.
Any idea what parts the supercharged V8 owners had to uprate?

I think you might be right on the gearbox front - gearbox failure just isn't an issue amongst these cars, or at least one that I've noticed.

Need to clarify, trailing arm is not interchangeble between the two models as there are differences.
Rear trailing arm is essentially the same design apart from the required changes to accommodate the V8, but on the V8 not used for the toe-adjustment. Front wishbone is the same apart from the droplink on the V8 that connects to the torsionbar.

Apart from the additional S/C, intercooler and various hoses and reorganising the alternator position, the V8 remains unchanged. No changes to drive-gear or suspension/brakes.

V8 trailing


Normal trailing

That's very helpful, thanks mate.

I realised I missed a couple of fundamental items from my list of necessary bits for this project... engine stand and a space to work on! Looks like I'll be buying a shed come workshop to fit at my dads place. The good news is he said if I sort that out plus a heater and lighting it'll mean he can work on it whenever he gets a chance. So much win.
