im a saturn enthusiast, the saturn community doesn't have much support as much as the honda does. im am recently building an s-serie beast which is a dohc 1.9 engine. basically the same stroke and bore as the b18a,b. they are both in the same neighborhood in power and torque and i have notice when boosted they create about the same amount of power. im in the merge of creating 400+ whp beast which is vertually never seen in the saturn community unless your boosting 25+ psi.

my question is in the ls/non-vtec community what turbo is making enough power to bring it upwards of 400 whp.
i was looking into a t67 from fullrace.com, what would be used in an ls an 82 or .63 a/r.
is alcohol used?
does anyone have an setups with dyno charts of ls making over 400 whp. so i can work form that and relate my setup as close as possible to a proven setup.

i will be runing a standalone, fully built bottem end. cams and head work with custom intake manifold and ofcourse exhaust. Tubalar, or log manifold? don't kno yet....

as much feedback is great just to get the maximum out of any setup.


thanks guys

by the way you can see my previous setup at

Good thing you decided to search more before buying into stuff. A T3/T67 is a turbo that will support about 700 whp and is entirely too big for your setup. Look into a GT30R with a .63 A/R hot side, mine is making 15 psi on a 1.8L motor by about 5000 RPM's, or roughly 1500 RPM's quicker than a T3/T67.

A T3/T67 would have a very poor powerband, what good are horsepower numbers if the car isn't fun to drive at all

There's a chart of a T3/T67 HO car. 685 WHP and it's not even maxed out yet.

19sec beast

You can check my 500hp B18B build in my sig.

Good luck getting your power.

on that gt35r what rear housing are you using

19sec beast

.82 ar

what would be the difference if i use that turbo and a gt35/t67r..... or should i just might as well go with the gt3582r.............

obviously the t67 makes more cfm but would not spool fats enough to create all the power i want out of it.

because i know a guy that has a saturn on a t67 on 20 psi and it barely make over 350 whp with no timing control.

the way to go would be the gt3582r you guys think.. what range rpm would that spool up and how much power can be created.

i kno in my t3/to4b with 3 " inlet after 10 psi i wouldn't make any major power increase. it would go from about 220 whp to 230maybe 240 on 4 psi more.
turbo was stuggling to make more power thats what i don't want with another turbo. saturn usually have to go bigger in size turbo than average 4 banger to make power needed.

hey, your post caught my eye because a friend of mine is the the process of building a saturn motor & he's always in my garage stearing at my b-series stuff.

One thing that i want to bring to your attention that we noticed about the heads is that even after a Porting & Polishing job that we did, your exhaust valves / outlets are EXTREAMLY smaller than that of a b18a/b let alone the vtec heads. We Measured them & they are actually about half the size. The intake on the other hand was much larger than the exhaust side. So getting air in, didn't look to be a problem, but getting it out looked to be quite a restriction.

With that info, i'm going to suggest purchasing a slighly smaller turbo then you would if you had a honda due to the fact that the thing just isn't going to flow enough air to spool it. Unless for some reason you've purchased a different head that has hella huge ports on it that would be compairable in size with that of a b-series head.

hope that info helps you out some.. i'll point my buddy brad to this thread later on & maybe you two can come up with some ideas together.

best of luck to ya

Power is going to be ultimately limited by the turbocharger, not the motor. If your turbo doesn't make as much power as you want it to, crank up the boost. Who really cares if you make the power at 20 or 30 psi, boost pressure does not break parts, and you're going to need race gas to make this power anyways. Run a GT30R, have a USEABLE POWERBAND, and a more fun car to drive. A T67 will make in the neighbourhood of 700 WHP be it on your saturn motor or a B18C motor.

non-VTEC

i would honestly seriously consider using a ecotec engine over the S 1.9L engine. the ecotec is so much stronger and more reliable. the S-series DOHC cylinder head has extremely small exhaust/poor designed ports and would require lots of porting to get to flow properly.

the S-series engine's seem to have some serious issues with head gaskets failing.....so adding boost to them would not help in anyway.

also i have seen LOTS of S-series engine single or dual cam throw rods out the block or spin rod bearings.........i don't know what GM was thinking when they designed that motor i just find it to be the biggest POS next to the 2.2L sunfire/cavalier engine.

the ecotec is a solid engine to work with.....there are lots of guys making good power with that engine and they can take the abuse. and there seems to be ALLOT of aftermarket support for it including right from GM!

as for a turbo choice if your looking for around 400whp i would choose a GT30R......

the 99+ s series head have a tinyyyyyy exhaust port im using the more usuable head of the early gen dohc. im adventuring the s -series motor becuae theirs a whole new world in performance that hasn't been discovered in this motor the fastest s -series car did a 11.2, wuth 390 whp....

a guy in cali named ian just put down 388 whp on 18 psi, and 426 on 20... which is not bad at all. im lookin in th range of 450 whp and try to brake a 10 sec barrier which has never been don'e in an s-series saturn.
