na to td conversion turbo coolant line questions

[R.O.R-2.0]

the garretts usually were fed by the 2.5 tho werent they?

and even being that they spool @ 2500, thats still going to add about 1k rpms to the spool on a 1.6L engine...

take that same T3, bolt it on a 350 chevy, and it will probably be damn near boosting at idle..

its all about the air you feed the turbo.. if you dont have enough to feed it, its not gonna operate the way you want it to..

(14psi on a T3 is nothing BTW.. its just starting to stretch its legs a bit)

No garretts were only on the 2.2s and the mitsu on the 2.5 which the mitsu is smaller. And yea that garrets good till about 20 lbs till it gets inefficient. But this was a non intercooled car so 14s plenty of boost for that.

The mitsu I think spooled 7 to 800 rpm sooner on the same engine I think so it might not be to bad if I port everything out

[R.O.R-2.0]

porting is not going to make up for 900cc's, and 1000 rpms more capability..

but go for it, atleast you will have a real good base ready for a real diesel turbo if you decide to go that way/find one cheap enough..

[bgbmxer]

Porting is how a Honda that's a 1.6 can run a turbo thats 3 times bigger than the one I plan on using and still make usable boost. Yes they rev higher and have more valves but do you think any 1.6 without tons of head work could ever spin a huge t3 t4 or bigger I think not.

I wish there was room for bigger valves and I would put bigger valves in too

Gas is a little different than diesel, but I see you have it all figured out. I will love to see a dyno report when you are done. Please keep us posted. It should be great.

Is this sarcasm? Or actual interest? And no I do not have everything figured out but there is one guy using the same turbo making big power so why can't I. Im not saying it's gonna work great but I don't see it being that horrible either.

i think it will work well, dave did 196whp with a t3 to4e which is much larger than the dodge turbo, who cares if its gas or diesel, our diesels rev nearly as high as a gassers especially with the governor mod.  the only difference on daves engine was a lightly ported aaz head and a giles pump.

5600 RPMs is a LONG WAYS off from 9000 like most gasser engines torn to make power with oversized turbos..

hondas can spool a HX30, because they spin ~9000 rpms to do it, and the turbo doesnt come to life til 4500 rpms..

We will see. I ordered pipe to fab the downpipe so no turning back now

Yea and that turbo is on a how many liter engine factory and is how many times bigger and flows more than the turbo I'm using?

lol, i was using it as an example, thats all.. nothing more.

Dont the rods fail around that horsepower?

[R.O.R-2.0]

Rods fail from torque.  If memory serves he was revving pretty high for that.

around 4800 IIRC?

you bend rods at low RPMS..

not high rpms..
