At that point it does not make sense to us. It works, but needs help to succeed. And all paths lead to a fair amount more to invest.

We picked the turbo up for 450 bucks. We had to at least try.

i like to put my compression test on his motor and see what it reads.

a few months ago, i got my motor to make 567hp at 21psi with 18 degree of timing before my oil pump took a crap on the dyno and i had to quit. i was only 33hp away from making 600hp on what people consider to be low boost. another pound or two of boost and 15-16 degree of timing would have gotten me there. you saw from the dyno sheet that i posted that the motor can make 550hp with 22.5psi and 13.5 degree of timing. that is with me not reving to 8500rpm. i am on a non hta gt35r with old school crower stage 3 cams. old school crower stage 3 cams are consider to be like hks272in/272ex but they are less efficient according to a test done years ago. i am running 11:1 wiseco pistons. i am on e85 so i can be retarded like that. my matco compression tester reads 235psi when i compression test my engine is cold. that is 75psi higher than 1g pistons and 55psi higher than 2g pistons. most engines that i compression tested with over the counter 8.3-8.5:1 je, wiseco, or ross pistons yield between 160-170psi if they have high duration cams. these engines with the lower compression reading generally make about 100hp-150 lower than mine at the same boost level even when they have turbos that are slightly larger.

the guy with the eclipse is running 9:1 ross pistons. we don't know how thick his head gasket is. we don't know if he has flat face valves or dish face valves. we don't know if he has welded combustion chambers or not. thin head gasket combine with flat face valves and 9:1 piston can easily kick his engine up to 10-10.5:1 compression ratio. if the head and block are decks to achieve .035 to .040 quench distance, i can see the compression increasing too. with welded combustion chamber, he can kick it up to 11:1 compression with no problem. combine the higher compression with a bad ass head and a efficient turbo setup, i believe he can make the power he is claiming on that boost level. however, the 600hp pump gas deal is very questionable. many guys claimed their cars have pump gas tunes when they sprayed a ton of methanol into their engines. i like to know if he is running methanol or not.
Thank you Dr. for the informative post. Lots of good info that I(we) can use down the road for the struggle. I just bet that your car is an a$$ load of fun to drive even with low boost.

Well we tried, but we just need like four 4G63s. But the new turbo should be great. Hopefully this experience will work in our favor. It sure taught us a lot.

LOL, what I find the most insane are the things you talk people into trying. More so considering the supporting mods but you never know...

While doing the final install on the new turbo, jason noticed a VERY large exhaust leak on the wastegate tube at the manifold. Of course this was pre-turbo, so it is hard to say how much, if any it affected the turbo's spool up. It was pretty decent from the carbon trails.

Even more of a bummer, as we may have had a shot at it. It makes sense why I could only get so much and why it fluctuated from 11-16psi EVERY pull. It was different every time.

Oh well, I know they work on a compound 4G63 setup, we just wanted to prove how a single could do and haul some ass.

We know for sure this new turbo will get busy.
