s10 1991 original 2,8L to 3,4L 24V

[S10-Heizer]

hi i'm from germany and my english is not so good!
i want more power in my s10 but i don't want to pay many for that and a 3,4L 24V engine is not so expensive!
but can i get this engine in my s10 without any probs?
i have a t5 manual transmission!
what do I have to change around this engine without problems to insert?
which parts gives it to buy around this engine to tune and from where do I get these?


i hope you understand me lol

English is much better then my German is

Anyway, there is a guy who put the 3.4 DOHC into a Camaro, I just forget his name. A couple things though not all:

-starter is on the other side since it is a FWD engine, have to drill mounting holes on other side
-not sure about oil pan clearance
-not sure if the engine is narrow enough to fit between the strut towers
-the T5 trans should bot up just fine, if you have a new enough (internally balanced) 2.8 you should be able to re-use your flywheel and clutch
-the TB will be pointing into the firewall, not sure if you have clearance or not for that.
-oil filter location? not sure if the RWD has an adapter or not

For the most part the 3.4 DOHC is the same engine as the 2.8, just a little longer due to the timing belt up front and much much wider up top due to the cam carriers

and what is with the motormounts are that the same?

Two things I will point out or clarify here...

There aren't strut towers in the S series truck, just things like the brake MC and fenderwells to clear.

Second, 1988 and up should all be neutrally balanced.

and what can i do now?
what 3,4L engine can i install in my s10 without any problems?

[S10-Heizer]

can i install a 3,4L 12V egine in my s10 with t5 transmission?



i don`t want to drive any longer with this 2,8L engine!
it has no power!

Yes, the 3.4 Litre 12v engine from a Camaro (93-95) would be significantly easier (the easiest choice), BUT, do you have those V6 camaros (and/or firebirds) over there?

If you were to use a 3400 12v engine from a Chevy Trans Sport, Chevy Alero, or otherwise, it will still be almost the same difficulty to mount as the 24v engine

But the 3.4 24v surely isn't impossible, just a bit more work.

alright but i have no information how i can put a 24V in my s10!
can anybody give me information how i can install a 24V or 12V?

[S10-Heizer]

we have very much us-cars in germany because i live in the near of the rammstein base and kaiserslautern!

[S10-Heizer]

can nobody tell me what 3,4L engine i can use for my s10?

[RidgeRunner]

Cliff8928 already said you could use the Camaro engine, or one of the FWD engines if you did a bit of work.

[S10-Heizer]

alright but what must i do on the fwd engines?

[Cliff8928]

You'll have to make custom engine mount bracketry.... The only direct-mounting solution is the 3.4 from the Firebird and Camaro.

You could always go to your local GM Dealer and order the 3.4 crate engine for your S-10 and that would be the easiest solution of all!
