Turbo a 95 say what now!? 750 that’s carbed

[Ghost]

Been thinking of trying to turbo my 95 ws down side is it’s carbed not efi is it possible any help would be great ty

[Gixer1460]

Of course it's possible, most of the turbo builds on here are carb'd installs - probably less than 25% use EFI as well. Check the site - most things have been discussed.

There is a search function - please use it or at least read through the whole of the Forced Induction part of the site - pretty much every question asked has been answered MULTIPLE times! Principles are the same whatever motor it is getting bolted to - just details change!

Is the search function on this website if so can u point me in the direction

This.

I was told I may have to make a breather crank case something to that affect I know in a car when built those I had to put a large breather in valve cover with catch can because of the boost lighten up the pressure in there

You can use the ‘oil filler’ as a point for fitting a crankcase breather.....but this is the least of your worries.

What is the c/r of them 750’s ? What type of pistons do they have (cast/forged)?

etc etc etc

Will need the breather if the motors left stock i reckon

Yes you will , larger and as many as you can manage - IMO, two 13mm ID pipes would be minimum

[Ghost]

Any specific spots where would u put them crank case top of head where that breather is not sure where else

I’m going to use je stock bore maybe slightly lower compression

On mine with an 1186 motor I had, one in oil filler, one centre of clutch cover, one on std cam cover breather and additional one on cam cover direct into the valve chest, that and the clutch cover were dash 10 hose, others dash 8 pipe.

[MeanBean49]

All depends what sort of condition your motor is in really, a good motor shouldnt really behave much differently than a stock one. ive never needed anymore than the standard cam cover breather and one from the oil filler. My cam cover one is just open and oil filler one has a pipe into a bottle, I get a tiny amount of oil in the bottle after a full trackday and never anything out the top breather hole. 

More holes means more places for oil leaks. 

As Viz said there are plenty more important things to worry about first, mainly getting the compression suitable for turbo use

[Ghost]

Ok sounds good now I’m just waiting on pistons and rods to come in I figured stock bore but I have lower compression pistons coming I’d like to run like 8 to 10 pounds of boost my son is a small guy about 5.1 and does not weigh that much he will be running the bike for me as a typical dad I’m nervous about him raceing the bike 

[Ghost]

Just looking at the placement of the manifold and turbo think I’m going to have to change the radiator turbo will be in the center of the v  Ferin behind wheel going to be tight

It's pretty simple, make sure the carbs in good condition, new gaskets and stuff, pitot tubes in the up pipe, and on that you connect the float bowl breather pipes.

 

Some bikes are sensitive on the size of the plenum, mine was, here on this site is also someone who got away with a small plenum. Rule of thumb, plenum size is 2 times the displacement of the engine. If I remember correctly..

My plenum is relatively small but the intercooler acts like a secondary plenum

Ok ty

Ah, that works too? 

My first plenum was too small, would hardly run of boost..
