DOHC beretta

[MATT2007]

I am wondering what would be involved in puting a DOHC 3.4 in my 91 beretta with a 3.1 I want to swap in a 3.4 and a 5 speed I should be able to get a 92 z34 lumina with a bad auto tranny. but will i need to get a nother donor car for the 5 speed swap also what can i do to the 3.4 for performace and what aftermarket parts are avable for it

NICE!!!

[MATT2007]

yea I hope she is a little bit faster when Iam done

[Hell_raiser]

it might be just a tad lol 210 hp should make it go lol it would have some prob getting it to the road lol my 3.1 spins under part throttle like well almost flood

[MATT2007]

I want to beat my buddys crx at the drag strip he has 130HP LOL I should have at least 210 and want to do mods to the motor I already have high paformance tiries on the stock 15x7 rims

It will take major modifications to squeeze a DOHC into a Beretta. There has only been 1 attempt that I know of (It was actually into a Cavalier, but basically the same), and I'm not sure if it was ever finished. I know it involved relocating the radiator, custom mounts, possibly even mods to the subframe. Its a big engine that isn't suited well for a small bay like the Beretta.

what about a 3400 what is the HP rating for say a 97 3400

[IsaacHayes]

3400 should all be about the same, it's just different cars had better exhaust than others. Around 185hp. Put on good exhaust and headers if you can, a 3500 plenum or 3500 heads on up for more power. Or camshaft, etc.

Or do a whole 3500 and use the external crank sensor adapter sold here on the store. The 3500 is 200hp stock and will be able to be ran with your stock wiring harness and computer. You'll need someone to burn you a chip of course to tuned for the extra fuel/etc, but there are plenty of guys out there, or get the stuff yourself it's not that much.

The 3500 would be a much better route as it's close the the DOHC's power and has a lot more lower end grunt and should make the power sooner, and fits the engine bay no problem.

I thought about a 3500 but thers not alot of them around heare I can aford
I am leaning Towards a 3400 will any car with a 3400 work as a donor car I want to mill .004 off the heads high performace cam if posible CAI free flowing exhust and mabey some other bolt ons

[MY91GT(Z)]

any car w/ the 3400 will work but ur best bet is w/ the 03 and newer ones as the have better internals and bigger ports than the earlier models and ben here can do custom cams and whatever else u would like along w/ doin full 2.5" mandrel bent and ffp udp and u'll be able to more than smoke ur buddy's lil import

tell me more about this. i am not familiar with the 3500. what does this product do? convert the ign signal it is using to a 7x signal for the older coilpack ign modules? also where is the external crank sensor located??

[IsaacHayes]

The 3500 has a different crank sensor and ring, and won't work with our ECMs. The crank adapter puts our 7x sensor on the outside of the crank pulley reading a ring bolted on instead of reading the crank shaft. Us with gen3 SFI motors need a 24x signal too, and we think that you can swap the timing cover and crank pulley from a 3100/3400 so we can use the 24x too.

Stock the 7x sensor is in the oilpan and reads the crank. This product puts it mounted outside reading a ring bolted to the end of the crank pulley.
