Already make plenty of low end power, but a turbo would just add a lot more to it and through the rest of the rpms. But I guess the lower end added power is the issue ?
Ive had my eye on some good turbo manifolds however, id more rather do a rear mount.
Question about boost.

Even more bottom end, then you could just chuck in a taller rear end gear and turn the extra grunt into speed instead of tyre smoke.TheRedWedge94 wrote: ↑Wed Jan 25, 2023 8:04 pm Already make plenty of low end power, but a turbo would just add a lot more to it and through the rest of the rpms.

Re: Question about boost.
Would you say heads and cam would be more reliable ? I have 3.73s and 25 inch tires, I burn out like crazy. Giving up some low end could allow for a better launch.

Easier to keep reliable and a tidier lighter solution.TheRedWedge94 wrote: ↑Wed Jan 25, 2023 8:32 pm Would you say heads and cam would be more reliable ? I have 3.73s and 25 inch tires, I burn out like crazy. Giving up some low end could allow for a better launch.

Re: Question about boost.
I put a small turbo on my bone stock 91 z28 daily driver. I even rear mounted it so i didnt have to mess with the stock engine bay. The ac still worked great and i didnt want to mess with it. All in all id say it made 350 hp. On just 8 psi. Pretty good considering stock 305 tpi makes like 200 and being old it probably was down some power although it seemed in good condition. I could have gotten alot more out of it but had valvefloat and some ignition issues I believe from a possible bad set of wires and cracked distributor cap lol. More boost didnt run any faster. It was a fantastic driver. Had decent boost response, it was very good when stock cat converter was on car. My guess was the heat kept in the system helped. When i removed it it got laggy so i changed turbo housing to try get spool back. Needed to try wrapping the piping I guess but it was good enough for me.
Turbo done right is a heck of a nice combo. I love cammed na motors and that instant power, but turbo is better mannered and more flexible in the power curve manipulation. Add on demand or whatever you want

Re: Question about boost.
How long did the car last ? Did it ever present any issues ? I figured running low boost like that should be fine, and even doing a rear mount, I could do all of the work myself; welding too. Better mannered, better throttle response. I would much more rather do a turbo over a cam, however I am doing what I can to make sure it is actually safe to do.
Re: Question about boost.
My guess it will handle it , but take a long look at Richards video's your will get addicted
just one phrase you said , if a cam can add 100bhp then the engine can take the turbo , i'd say yes but your view is wrong , generally a cam will move things to the right and a small increase in tq will net vast amounts of hp , BUT ,
look at f1 , the produce piss all tq , and especially old v10 v12 v8 n/a , and that's a kinda easy to get things to live , tq brakes and smashes everything , but at what your talking , say if you had crap oil pressure , lf wore bearings , the vast increase in tq low down probably 10x what the cam would do at the wrong end of the curve , puts more cylinder pressure at less ignition , pressing on the side loading of the piston and squeezing out he oil if not up to the job , so on that side it cannot be said that once it can take 100bhp it can take the boost , as n'a might bring 30lb tq where as the boost will be 110-180lb tq , but the n/a will be to the right where things are moving faster , and the load lasts for a far shorter time , and time x load is the killer so this is why the statement cannot be made ,
case in point , the little 1.3cc we do , on a std turbo with proper ecu set up , i pushed as we can make another 100bhp on these engines that come std turbo from the factory , but with the decent ecu , the turbo is to small std and falls on its face early , but we were heading towards an extra 50bhp at the std boost , where we made over 100lb tq low in the rpm , 3400 , bent the rod , but yet with fuel controllers and extra boost these can made nearly an extra 100bhp , just not the tq so low , but several survived with the extra tq at an extra 1000rpm for years
aside , id say u will be fine , ring gap excellent tune and don't bother with the cam , boost under 7psi can get away with no intercooler
