saab engine in tr7

[geevee]

Can you use a saab engine in a tr7? if so what changes need to be made to accomadate the engine. There is one for sale in my area and looks like it is a 16 valve.....I'm thinking better performance.

thanks for your input.
Gary.

..hey geevee hello .. if it is possible make some pic!!

Only the early 1850 Saab engine - which in fact was exactly a Dolomite engine, even down to 'Triumph' on the cam cover. I had wondered about this too - but sadly it seems for some reason Saab went their own way.

You need to use a Vauxhall carlton gearbox, scratch built prop and engine mounts, the engine from a transverse 1994 onward saab and you will probably have to modify loads, but it can be done and the engine is good for 400bhp on stock internals.

Ahh - glad to hear nothing is impossible !!

..hello Richard, bmcecosse and geevee.

Yes, in any case, it is possible to the B234 from 1994 can be used with the Getrag R25-28, Opel Omega or Manta, respectively. Vauxhall needs to be connected to the Flywheel of 9-5 this disc is the thicker you can see: below ..

The problem is the engine is relatively high as to 56cm without Oilpan and you can not use the TR7 oilpan ..

The old engine B202 fits the Oilpan but the gearbox is not without an adapter flange plate .. The Inlet manifold and the exhaust manifold must be manufactured specifically --

There could also be a Mazda, Toyota or Nissan engine that gives it all with Turbo and rear wheel drive .. But it is a complete rebuilding - not to mention the Rover 620 / 220 Turbo 220PS and with a Sherpa bell to the TR / gearbox mounted ..

So whats best ?? For me it is important:
- The engine has lot of reserves and have a long life, and easy to get parts.
- Not to make series Body adjustments (except motor brackets), and here in Switzerland, it should be suitable roads!

So I can only make an almost original approach dolly with injection engine or the B202 but this is a lengthy project ..

even a V8 is a possibility but ther i need he paper !!

ive read all the threads on the forum about saab and triumph matching.

but nobody explained is it possible to fit an saab 2.0 b engine 16v head on the tr7 2.0 engine block.

as there are lots of rumors about that it is posible

Frank, no love for Mitsubishi? [;)] Which makes the best (and cheapest in US) 4 banger?

But I agree with your general point: if you are going with a completely custom application (engine/tranny assembly), then why bother with Saab?

Marko, from everything that I have heard, Saab head will not fit on Rover block. And if you are so inclined to keep the Rover block, why not go with the Sprint head?

becouse it would be easier to find a saab head here where i live , i have the only tr7 in the country( in working order)

[grndsm]

I understand your predicament, but you are still much closer to the England than I am. And from what I have been told, Sprint heads are somewhat common and relatively cheap on that island. [;)]

yes they are , but there are some bad and evil man at the border called customs and they take money from me when i buy something that costs more than 50 euros;.

i payed rear bumper cover instead of 90 punds , 250 pounds [V][V][V]

[frankman]

ohh [:p] sorry grndsm I forgot the Mitsu cool power full engine ..


Hi Marko, I understand your concerns and thoughts, I played all through but it is not easy to make something of Cylinderhead, TR7 respectively. Dolomite has 5 straight and oblique 5 bolts with whom he was attached! When Saab 8V from around 1979-80, they just all strait screws in the head ... You look at the best you a head gasket (send you an old one and the 16V Saab cylinder head with Hydrostössel is also different, front which means the chain coverage is different completely the Block B from 1984 to 93 other design has no more in the engine halfshaft The distributor of waterpump separately from the camshaft driven at the head ...
I thought why not even the old Saab engine with the larger crankshaft bearings and the head Dolomite new drilling but it goes too far ..


Marko But it should not be a problem a cylinder head here in the Schweiz or Germany to find and you have certainly relatives or friends in Switzerland or Germany, and in the Vacation could take a head ..

I dont know the rules in Croatia but if they are looser here than I would a 234 Turbo or Mitsu ... As mentioned above is fitted certainly the easiest way..


I would be happy to give you a massification of the TR7 engine gearbox plate

I have a lot of photos where the differences between the two engines are to be seen and I have a cellar in the B202 engine block is .

[Marko]

thanks for the.offer but im only collecting my options for now.

first i want to get the car back on the wheels with the standard engine ( 8v head).

second step is a standalone ecu on it ( probably megasquirt , or if it will be complete ,an ecu that my team i building.)

this Tr7 engine if you look at its geometry, should rev like satan. ( bore stroke : 90.3/78) the big diameter of the piston means it is less prone to knocking than a regular 2.0 litre engine since the flame front has more space to expand at its burn rate. in comparison an s2000 ( thats a honda) has 87.0 mm bore and 90.7 mm stroke and it produces around 240hp

the problem is how to fill it up with air.

you can ad 2 more valves per cylinder on slap on a turbo.

or ever better , do both

the one advantage of the 8v + turbo configuration is that you have less parts in the engine head (like valves ,seats and springs) , so it is cheaper to replace them with better components.

Marko, I must disagree with several of your points...

First of all, rather than focusing just on bore vs. stroke ratio, you also need to consider connecting rod length. That would give your rod angle, which also determines engine’s ability to rev high.

As for larger bore, it makes it MORE difficult to achieve even, controlled combustion and thus it is MORE likely to experience knocking!

That it is one of reasons why "larger" bore engines sometimes have to use multiple spark plugs. And when the bore gets big enough, it is simply not practical. Which is why all (most?) large engines are diesels and do not require any spark plugs.

there is no such thing as even combustion in the todays Otto- cycle engines. the closest are the direct injection petrol engines ( for example. FSI from vw ) and that is still far from the ideal Otto- cycle.

longer burn fronts don't always mean higher chances of knock

you cant compare otto and diesel engines. especially in the construction.
in theory Otto cycle is more efficient than diesel cycle. but diesel engine construction is much closer to the ideal cycle than otto.
