Turboing a 305?

[nicholas9walter]

My friend has a 89 rs with a 305 in it and instead of switching engines which is expensive. we can get turbo parts,downpipes,and intercoolers for very cheap. I have no experience working with bigger engines so i was wondering if it is even worth doing and how to do it? any help would be greatly appreciated, thank you.

Turbos are a good way to make power. Depending on how many miles are on your engine though it may not handle a turbo for very long because it could be worn a weak.

[nicholas9walter]

well its got 88 thousand miles and he has replaced many parts, now i'm just trying to help him gain soem power, but like i said i dont know how to work with engines like this so i need help.

[instantkevin]

never turboed anything in my short life. So I won't be of much help. But you did peak my interest when you said cheap. Can I buy cheap turbo parts from you? Sounds like you got the hookup.

[nicholas9walter]

you'll have to tell me what you want but im sure i can hook you up.

[nicholas9walter]

so does anyone on here know how to go through the process of turboing the 89 rs?

talk to Hypsi87, he's a forced induction god

Well. I don't know if it's worth putting a turbo on that engine. I know I'm a newbie, but I used to own a 91 RS with a 305 TBI engine. To my recollection, it puts out 170 horsepower. Don't get me wrong, but I think the throttle body injection in that car will hold you back. Now turboing the 305 TPI engine in the z28, now that's a different story.

The 305 is not a very good platform to build up. I was under the impression that a turbo cost is high, but I really have no experience with this. Either way, I think your best bet would to be an engine swap to get more power.

A 4-bolt main 350 is probably the cheapest, most reliable engine to build, and it can be done for cheaper then what you think (we sold a 355 race engine, with 13.5:1 pistons, steel rods/crank, .630 lift roller cam, cast iron heads w/2.08 in. intake, 1.60 in. exhaust valves for $2500 a few months ago-it would cost a little more to build that engine, but not by too much).

My point is $3500-4000 will build you a pretty stout 355 (of course you have to do the work yourself).

ok thanks a lot

i have a mildly modded 305 tpi that would take most stock l98's with ease but thats neither here nor there...personally im looking at making my own 'electric supercharger'. before you laugh at the idea lets take a logical approach to this project...assume you can put together a simple electric fan hooked up to an intake that takes a k&n cone filter, and assume that somewhere such a fan exists that can overcome the wot suction by maybe 3-600cfm over (and yes, i mean WITH STABLE PRESSURE, not a static open air fan that would hang in space), thats usable, cheap horsepower without downpipes, expensive turbines, intercoolers etc. it can also be done without using huge power supplies, even if it was run off a secondary battery or batteries on its own it could work. that seems to be the only problem with these setups is getting the power to it but hey ever hear of thomas knight? it can be done, it will be done, and ill let you all know how it turns out :-D

Too bad a simple fan cannot create 'pounds' of pressure.

[sykotic1]

get real bro, a simple fan, obviously you already have something in mind. an electric fan could be as simple as a computer fan or as complicated as a 20,000 cfm exhaust blower, fabrication is the key of course its not gonna be something i pick up at lowes or my local pc store lol. i guess the answer to who that guy is would be no for you hmm? somebody needs to do their homework.

[sykotic1]

in other words, an electric fan most certainly can create psi, just not while its hanging in space. if youre going to argue with me here then argue this sentence: electricity CAN be used to create a forced induction system that produces measureable boost without traditional forced induction methods. that means an electric fan or some variation. ill even give you one up and argue that you can go upwards of 15psi, its been documented kid do some searching before you open your mouth. as far as the power supply, hey, i dont care if id hafta have a heavy duty SDS sitting in my trunk, if i could save thousands over what it would cost to have someone install a traditional super or turbo charger, create a unique custom system that really works, and actually produces decent power, i would do it in a heartbeat.

[96Civ]

15 psi? are you living in a dream world? I have done my 'homework' that you keep refering to. All the electric superchargers out on the market today produce only about 1-2 pounds of boost. Spending $300-$3,000 on a few pounds is just IMO, dumb.

Turbochargers are just better... Sorry to break the news.

It's nothing new. It has been done before, so go do your homework before you start to think it has been 'your idea' in the first place.

Go 'fabricate' the thing and let us know how it goes.
