Sprint engine

There is a Sprint engine on ebay with a bin price of $5000. Is this resonable?

Sounds kinda high (for my taste). Id spend maybe $2000., but not $5000. depends on how bad you want it.

Rimmer sells a Sprint conversion, including uprated brakes, for a lil less than $3000. thats the route Id go if I had the green.

I would never pay that kind of money on an engine someone else built, used and comes with no guarantee.
But if you want to built a high spec Sprint engine it can easily cost much more, so what is wisdom ...

Can't find much flaws in the advert. Only thing wrong in the advert I can find is the following contradictions;
<blockquote id="quote">quote:<hr height="1" noshade id="quote">Performance is strong all the way through the red line<hr height="1" noshade id="quote"></blockquote id="quote">
<blockquote id="quote">quote:<hr height="1" noshade id="quote">never revved it past 6,000 RPM <hr height="1" noshade id="quote"></blockquote id="quote">
From own experience I know that a Sprint that revves through the red line (@6500) will be over @ 7000 rpm before you can bat your eyelids. But that won't do much harm if everything's in proper working condition [:D]

"170-horsepower"

Seems a little optamistic on either of the carbs mentioned with a STR091

Beans, or any others, do you have experience of a tuned [say
150BHP+] Sprint engined 7, compared to a Rover V8, of similar BHP,
engined 7. And also what, if any, is the difference in driveability
between a sprint engine, & a tuned 8V of similar BHP, in a 7.

My knees are getting so bad, that some days I have trouble getting
into the DHC. I am thinking of building a daily driver 7
convertable, & am wondering which would be best for me. I would like
a bit more performance than my stick[ish] 7, without the excessive
fuel consumption of the 8. Besides, my son is making noises about
wanting to take it to Sydney, with him for a while, [1200Km away].

As we average only 3.5 wet days per month here, I'm thinking of a
hoodless car, with a good tourneau cover to keep prying eyes, & the
odd shower out.

As I've never driven a sprint, 7 or saloon, any advice would be
welcome.

I can appreciate the benefits of a Sprint engine in a 7 but have never driven one.

170bhp is easily achieved by a Rover V8 in a relatively low state of tune and much more torque is available at low revs. Power and flexibility in one. The money saved on buying a V8 instead of this Sprint engine could go towards the extra bits needed on the conversion.

The seller appears to know his stuff but even if it is all genuine, it's still a used second hand engine as Beans has stated. Plus in this state of tune, the fuel consumption won't be that much better than a standard Rover V8 in good condition.

V8's sound so much better as well, the seller agrees!

Jeez Hasbeen, I hope he's got somewhere secure to park it there. When I was last at Fleetbase Sydney, out of all the cars parked there my old Volvo 265 wagon was about the only car the bloody junkies left unmolested, all the other cars were regularly left on bricks, stolen or vandalised (eg. All windows smashed) I guess not even the dirty filthy smackhesds of the cross wanted to steal a Volvo!
I wouldn't park any car I still wanted any where near the base or the surrounding Wollomoloo/Darlinghurst/Kings cross area

No problem there Cobber.

In our modern vavy, only the duty watch stay on board, over night.
The navy pay a very large rent subsidity, so all the sailors live in
the suburbs, & catch the train to work, just like office workers,
when the ships are in port. With these old tank landing ships, that
is very often.

He has a unit with a private, 2 car underground, [on an elevated
sight], lock up, garage. He also has a $500 Toyota Cressida, for
driving to the base, if he has too.

Hi Phil,

Your left knee will get more of a workout driving a Sprint engined wedge over any other engine.

Simply, the engine wants to sing much more than an 8 valve, and being the boy racer we all know you are, you will use the top end of the engine much more, and get much more satisfaction from it.

That's not to say you can't drive it more sedately with minimal stick. My sprint has more torque in the 1500 to 3000 range than any other 8 valve I have driven. It is easy to drive it like a limo short shifting just over 2200 on most roads.

You can tell she does not like it as much as changes between 3700 to 4800, or higher if you both feel randy.

Compared to a V8 tho it will still seem laboured.

Agree with Owen.
My Sprint (with between 152.5-165 BHP measured at the wheels) really needs to be trashed to be quick.
Due to the cam (GP2 rally) and the 45 DCOE's with 36mm chokes it doesn't have much torque at lower revs.
Starts to pull @3000rpm, but really takes of @4000 rpm.
Power band is fairly narrow, best to keep it between 4500 and 6500 rpm.
But then you'll need a pretty good V8 to keep up with [}:)]

Smaller chokes and a less hairy cam will probably make it more drivable at lower revs.
But nothing beats going up the north face of the Stelvio with the engine revs between 5000 and 7000 rpm [:D]
