I know this thread was done before, but no serious answers were found in that thread!

I was thinking something along the lines of Jet's turbo, PTE SCM61 with a T04S housing. After talking to Kevin at AGP he suggested I should go full garret.

Anyone have an opinion on this? I know AGP's RS65 flows 65 lbs/min and is very similar to the PTE SCM61. I thought that would be a pretty decent turbo for the 2.4 and as spool isn't much of a factor.

I know Marco is running a GT35R now, any opinions on this turbo?

Maybe another T3/T4 combo, or even full T4?

I have no idea...Damn this is complicated!

Chris

PS - My goals, for anyone interested, are 10's...At least once before everything breaks ;)

You want 10s? Nash did 11.2 on the 20G. I have to say the PTEs are very nice and are getting more and more common, but your missing some pretty bad ass turbos on your list, that are made by Forced Performace. The 3065 would e a nice addition to your setup. :-)

JET 02-12-2004 10:38 PM

PTE 50 trims will do 10's, so the SCM61 (RS65 is identical) will easily do it. This should be a perfect turbo for a normal 2.4l. Full spool in the low to mid 3k's and capable of over 600 hp (if the exhaust side will flow that much?)

Shane@DBPerformance 02-12-2004 11:08 PM

SC61/SCM61, FP3065/3565, RS65, GT35R, SBR-GT14, BR580, VPE GT3040, VPEM61, GTM61, etc. These are all essentially very similar turbos sporting the same GT40 compressor wheel. Some of them are the exact same PTE turbos under different names. The compressor wheel is rated at 60-65lb/min depending on which web page you believe. So it flows a lot of air and it is also very efficient everywhere from 10-30+psi. The main differences are do you want dual ballbearing and what do you want the exhaust side to be like. On a 2.4l you could get one to spool before 4000RPMs with the decent sized exhaust side.

You could run 10s on a 20G or 50-trim with a 2.4l if you wanted. It would like how people run mid 11s on 16Gs, it woudl respool those turbos extremely fast between shifts and you wouldn't be wasting any time going down the track. If you just want to make stupid amounts of power then look into a T3/T4 SC61 like Ben suggested or an FP3065.

i have a T04E that i have been trying to get rid of. in perfect shape, i never hd the chance of using it. if you wanted just let me know. i can have pics of it when i get back to the U.S.

Alrighty, just talked to Kevin at AGP. Man does that guy know his shit!

Basically he suggested that on a 2.4 the exhaust housing in a hybrid such as the RS65 may be a little small. He suggested a full garrett kit with a larger .83 AR housing, such as the GT35R. He said that the GT35R runs the same ultra efficient 56 trim GT40 wheel with a larger exhaust side, which would provide more for the 2.4

I wasn't very interested in getting a manifold and the whole kit, but he does make a good point. Do you guys have any input or opinions on the exhaust side of a mitsu/garrett hybrid on a 2.4 litre? Also any other advantages/disadvantages to going full garrett? He said $1650 for the whole kit.

Thanks!

Garrett GT60 :bounce: :3gears:

Shane@DBPerformance 02-13-2004 09:29 PM

Does the $1650 include a ball-bearing GT35R or a normal bushing version of that turbo?

The only disadvantage to a full Garrett setup vs a bolt-on is price. You need a different exhaust manifold and O2 housing. So it costs a lot more.

Going full Garrett is better because you get their exhaust housing that matches their exhaust wheels with a bigger a/r selection, instead of using a hybrid with the Mitsu housing or somebody elses idea of what the exhaust housing should be like. But the conversion does cost a little more as you've found out.

v8klla 02-13-2004 09:58 PM

Kevin told me that he could do standard bushing of any ball bearing turbo. I am not sure as to what the price he quoted me was for, but he said $1650 for the whole kit, including manifold and o2 housing I believe.

You need to decide if you want a fun car or a race car and be honest with yourself about it. If you want a race car then you should skip over everything and go right to a full T4 set-up.

I listened to people who were supposed to be "in the know" two different times and it wasn't anything more than an expensive pain in my ass. T4 was fast but I don't spend much time over 30psi on race gas. T3/T4 wasn't bad but it still wasn't what I was after.

Finally I went and made my own decision and bought the turbo everyone thinks might be too small. I went back to a 2g manifold and put a PTE SCM61 on it. This gave me the car I wanted.

The car's fun to drive, at 18psi on pump gas it has power instantly in any gear. I get to make the decision to use race gas and turn up the boost, it isn't a requirement and if I want to use it 30psi on race gas is still an option.

It does seem like 30psi is about the limit of this turbo on the big motor but I'm not trying to chase down Sheps times.

v8klla 02-14-2004 12:55 AM

Well I want it to be streetable, as in spools before 5000. Hopefully that won't be a problem with the 2.4 setup. I would like it to be efficient on pump gas though, as I am not as wealthy as say Sam Jacobson and cannot run race gas every day!

Like I said I want 10's, but don't want to have to upgrade the turbo again anytime soon...

Chris

BTW - What motor/supporting mods are you running? I see you are new here...Welcome!

1ViciousGSX 02-14-2004 07:16 AM

Basically the 2.4L will spool a turbo 800-1000rpm sooner than a 2.0L will. So just keep that in mind when looking at turbos which are ussually rated for 2.0L engines.

Pushit2.0 02-14-2004 11:49 AM

GT35R or bigger other wise you ARE WAISTING YOUR TIME with a 2.4.

With a 2.4, get a turbo that you can handle or JUST BUY my 14b ;) , a AGP/HKS/Buschur T4 manifold, and call it close.

Shane@DBPerformance 02-14-2004 01:39 PM

A GT35R is pretty much a dual ball bearing version of a SC61. Even though the 2.4 will spool a turbo faster, you have to slightly offset potential RPMs that you are going to lose on the top end. The 2.0s rod ratio is pretty good and you can rev it quite high, most of the fast fast guys are running 2.0s and running high RPMs. The 2.4 rod ratio is quite poor, even the log rod versions are only slightly better. So you have to somewhat take that into consideration. For a lot of you that might not be a big deal, but I ran my ghetto half built 2.0l to 8500 almost daily and I would be scared to run a 2.4l out that far at all. Higher RPMs make for some nice long gears.

Guys are running 9s on turbo based on the wheel in the GT35R/SC61, etc. So it is quite capable. If you want it to spool fast then maybe just get a Mitsu version of it like the SCM61, if you want to make more power with it then get a T3 version of it and run a bigger exhaust side.
