Hello, I am currently getting my Ralliart turbo charged. At first the turbo was supposed to be a GT28, but they said that there were too many problems with the Ralliart computer, so they are downgrading to a GT25 instead. I was wondering, if I run the same boost, will my GT25 produce equal power to the GT28? I will be running only 5 or 6 psi, so will I be losing out on power since my turbo is smaller? Also, Later on when I have more money, how hard is it to upgrade my turbo to a big GT35? Will I have lots of problems? Because on the forms, I ran accross a Ralliart pulling over 400HP, and he is using a GT35, running at 20 psi on 91 octane.

call rrm. no one else on this board know the secrets... -=\.

I would, but I don't think that they will be able to help much since I will be using a different setup from them, and I am using a different Turbo too. I think RRMs stage 1 kit is using a 16G, and last time I asked, I think their stage 2 uses a T28 turbo, not the GT28, unless I am worng.

turbo size shouldnt affect the computer at all...... boost is boost flow is flow.....

20 psi on stock internals??

Yeah, i think he's talking about turbotech PR, who turbocharges anything with a motor. He's got a 500+hp ralliart in Puerto Rico.

dunno he said he ran across him and hes from canada. i dunno.

Sorry, when I said "ran accross" I was talking about over the forums. Not from Canada. Sorry about the mix up. As for the turbo, They told me that the GT28r was blowing too much air for the engine to handle, so that was acreating problems. I talked to my friend, and he's using a GT28r, his was the first Turbo Charged Ralliart done by Essential Speed. He said that his system is stable now, but Essential Speed told me they would not give me a GT28r.

Yes its true, we don't like giving away our secrets, but we do like helping. As for your turbo issue, and turbo should work as long as it fits really, and you know how to make it work.

If you want to see if the GT28r matches the RA 2.4L engine, compare the CFM requirments. Find the compressor map of the GT28r and do engine flow requirments for the 2.4L. This website has a javascript calculator......

I believe your redline is ~6200rpm...use 95% for VE and density ration is a ratio of boost w/ respect to 14.7 so if you are running 14.7 lbs of boost then density ration woul be ~2.

You would want efficiency level of the turbo at ~75% near or at the torque peak of your engine. Not knowing the spec of the GT series of hand, i couldnt tell you exactly what you need....but if the GT25 is anything like the T25 from 2ndgen DSM, you will need to buy an asthma inhaler for the turbo cause its gonna be out of breath up top

there ya go all about effiecency....


Turbo tech is not running on stock internals you dont pull over 500 WHP on stock internals haha

UTEC hes running i tink

TURBO TECH P.R.

you rigth,i do modify the internals,i got crower rods,ross 8.5.1 forged pistons,and electromotive tec 3 fuel management system my last dyno was 508 whp and i use that car every day,i got 3 difrents boost set up 14 psi.20psi,30psi with race gas.

How did you get Crower and Ross to work with you... i sent them each 3 emails and the only company i've contacted about internals and got a response was Pauter.

TURBO TECH P.R.

hello my friend i do have an extra set of ross 8.5.1 forged pistons the i make when i build the engine,and for the rods, the ralli art use the same rod dimension of the second generation 4g63 2.0l,eclipse,evo.let me know if you need some help.
