3400 250HP Naturally Aspirated?

[Guest]

On the face of it, the 3400 would be preferable to the 3.4/3.1/2.8, but it won't fit with the stock intake either, and you have to accomidate the reverse side starter and what have you. I only know of one guy who put a 3400 in a Stalker, and it's been a struggle.

I don't understand this statement, The 3400 overall is Shorter than an iron head equivilant, especially a carburated or TBI version.

The Intake can be turned 180°, to move the TB to the front. The front cover can then be modified, where the power steering pump was or use of an iron head longitudily mounted front cover, water pump, pulley system is even better.
The Trooper (equipped with a 3.1) or a late model S-10 with a 2.2 have a tranny that will accomodate the driver side starter mount. There was also an early F-body bell housing that had dual starter pockets.

The struggle might be more from the electronics, to use the 3400 SFI PCM will be very difficult at best. I'd recommend going to an MPFI ECM from a '87 to '94 J-body, '87 to 93 W-body, and a few other vehicles. This will run the engine in bacth fire, as opposed to SFI, but it's 300 times easier than using the SFI.

Check out www.domesticcrew.com for swap info. That site is geared towards J-bodies with a 3400 swap, but there is other info that should help, plus there's a few of us on there with some oddball combinations. Like my Jimmy, 3.2L Hybrid with a turbo.

Go with what xonelith did cam head job and full exhaust (BAM) 200WHP http://www.milzymotorsports.com/ they have everything you need full heads and the cam $1400 S&S makes headers+cat for $850
Manta part makes Rods for the engine and you could get custom pistons then spray it to over 300HP. but that will be another $1300
Good luck

Our site has everything but the cam, and I recommend a regrind vs the cost of the billet cam unless you can get specs that aren't milzy's. Rods are easy, no need to go to mantacrap and get raped. pink rods can bemodded, or crower makes some that bolt right in but they are a bit more expensive. No need to do shit to the rods for NA though other than a good deburr and shotpeen if you have any worries at all.

As far as fit is concerned, the hood scoop would have to be altered on the Stalker, as it is tall and narrow, and the main hood barely clears the valve covers. This is pretty minor however.

Perhaps the other issues that you note are easily surmountable. Generally the Stalker is a dream to work on, so if you've cut your teeth doing mods to J-bodies, yeah, the conversion might be pretty easy.

It's nice to see those 3400 dyno charts. There's a lot of talk of 3400s and Hybrids, but I haven't seen much hard data till now. 200 plus RWHP sounds mighty tasty!

Sorry to go out of the 60 degree mold here, but an interesting engine for the Stalker might be the 2.4l Ecotec from the Solstice. It gets 170 HP in NA mode and I bet there are people out there marketing turbo kits. I could see it easily getting 240 - 250 with a spooly thing. The engine is a small RWD aluminum block engine so it would probably fit very easily and weigh a lot less than the 3x00.

The Ecotec is making well over 1000hp with a spooly thing...

thing with the 2.4l ecotec is support system. you would have to get every last sensor, controll module, wiring, ect out of the car to make it all work, and dont forget that it uses the electronic steering. to run stand alone, you need to get an older 2.2l eco intake and throttle body being the 2.4l is a drive by wire setup. the other big issue would be the variable cam timing, being no stand alone ive heard of can run that. my guess is that you would have to convert back to older cams and timing chain. in the end, you would lose what made it 170hp, and may aswell start with a 2.2l ecotec and turbo it.

im on and off playing with my buddies car. its a 2001 sunfire gt the had a built up turbo ecotec swapped in. the motor was built to run 36lb boost and have 600+hp. im guessing its about 300hp right now at 12lbs boost. he doesnt have the fuel mods to support running much more boost.

1) Slightly Modified
2) I believe we're talking about doing a RWD setup in this thread. Theoretically the reason that GM doesnt push more than 1100hp in their ecotec drag cars is cuz the tranny cant hold any more power. Perhaps in RWD it can?

[sharkey]

they do run a rwd eco aswell, its pushing 1100hp aswell.

btw: gm has an ecotec powerbook, it tells you everything needed to get 1000hp out of it.

Guys, I have a 3400 minivan motor here that from the centre f the crank to the top is:
18.0 inches to the highest point.

A 93-95 3.4L Camaro SFI motor is: 17.5 inches from the centre to the top of the TB which is the highest point.

Which is taller now???

Measuring from the oil pan? I have not done, but could. When installing most motor conversions, you need to look at the crankshaft-gearbox input/output when installing in a car and fit that up with everything else, that is why i measure from the crankshaft.

Also, from everything I understand in the Stalker and the ones i have seen, the 3.4L is going to be a bolt in whereas the 3400 is going to only be bolt in for alot more money although it can be done.

I know there's the Summit racing cavalier that's RWD, but for some reason last time I saw it they said they have a 6 in it. I know they have a Ecotec book. I noticed in the GM perf. parts catalog they have ECOTEC parts as well. They dont sell piston rings for it, but it gives the PN for the rings they do use. Even that's helpful.

As far as the support system.... would you really need all of that? I mean, there's gotta be something that would work acceptably. Maybe not for a 2.4 ECO, but there may be something that'll handle the job enough of what he needs done. Same with the steering and other stuff.

would the $700 kit frrom there cover putting a 3100, 3400, or a dohc 3.4 in my 92 firebird? the 3.1 i have in it is shot.
