It goes on Friday :)


Tuned to on a Mustang Dyno :)




Yep, its the RNR 50 trim turbo kit. I stole this thing, brand new and yeah I still like the Garrett GT30R's but this kit was less then HALF the price, I couldn't NOT get it. Brand new full kit comes with everything.


The FMIC is TurboXS and I have Some Precision 680CC injectors which will flow this badboy perfectly.


I cant wait, it goes on FRIDAY and will be tuned :)

I plan on purchasing a 50 Trim once I get back from Iraq. I'm curious as to how your tuning came out. Also, I'd be willing to bounce some of my ideas your way to see what you think of them.

Believe it or not everything fell to shit. I actually went to PDT to have it installed, they gave me such a creepy feeling I simply left as they stared at me. They were ina run down shack in Philly which I felt I could kick over. Just wasn't worth it. In retrospect it was the greatest decision I EVER made, EVER. It also turned out that 50Trim kit pictured above had the POS .48 Exhaust housing which would kill any serious topend (60WHP Less!!!!!!!!!)and then the lag compaired to the Stock turbo so in fact it wouldn't be MUCH faster, maybe up top, certainly not in the 1/4 mile in comparison to the stock Turbo.

As far as the Manifold it is VERY nice and VERY heavy, won't break. Make sure you get a BB 50Trim and if you have the scratch go for the AMS kit. It is WAY WAY WAY overpriced but fits very nice. The RNR has SOME clearance issues and their 02 Housing is a POS but it works. Buschur's Kit is actually VERY nice and will make the same as any other kit for well over $1000 less and be low key with the Cast manifold that allows the STOCK heatsheild to remain, VERY trick.


Go Buschur.

FYI my Evo VIII is GONE I have a Evo IX MR :)!!!!!!!!

Brother.

Straight up. I'm sorry that things got off to a rocky start for you. It's so hard these days to take our cars to reputable tuners/installers that are close to where we live. We're almost at the point of choosing the lesser of two evils when it comes down to tuners/installers around our local neighborhoods. In my defense, I do have three friends here in Killeen that know the in's and out's of DSMs/EVOs. They go by the name "DEM". On any given day, you can find them doing turbo kits, engine swaps, and everything in between.

Oh yeah. The 50 Trim? I have a trusted friend who's selling me his "never used" non-ballbearing 50 Trim kit for $600. Reason? He's buying a custom 500-ish whp STI this weekend and therefore has no need of the turbo anymore. The major things that I still have to buy is the Tial 38mm wastegate and a nice turbo exhaust manifold. I was just given the "go ahead" by my financial advisor (wife) to build around the stock turbo and then this opportunity came along. I figured that $600 for the turbo, roughly $350 for the wastegate, and roughly $550 for the turbo exhaust manifold, plus the small things needed to complete the install would be worth a shot. That comes out to around $1500. That's still cheaper than the BR 20G-9 that I was going to buy and I'll have more power on hand, of course, with an increase in spool time. I am going to be running my Engine Runup meth/alky kit along with the remaining supporting modifications. My goal is to have a streetable 450whp setup.

Bottom Line: I've done all of my research on building around the stock turbo and I'm comfortable with the "plan" I had before being introduced to this 50 Trim turbo. The 50 Trim, like I mentioned earlier, will cost roughly $1500 + installation fees. And the BR 20G-9 will run somewhere in the woods of $1700. So there you have it. Stock? Non-ballbearing 50 Trim? Buschur Racing 20G-9?

I'd love to have the oppertunity to run a 50trim. With their effeciency you can run 91 octane and make great power all day long. If you have friends with turbo install experience, you guys can throw it in no problem.
My $.02; go with the friends and the 50 trim.

turbolarry,
will you explain how the more efficient turbo can make better power? I have been thinking that 20 psi is 20 psi, and if I am not going to raise the boost there is no reason to upgrade the turbo.
It sounds as if you are saying you can get 20 psi and not have knock worries with a more efficient turbo.
real question, I don't know

20 psi out of the stock turbo is not going to be the same as 20 psi out of a 50 trim.
A more effiecent turbo makes better power because it doesn't heat up the charge air coming out of it as much. The cooler the air the more dense it is with oxygen molecules to mix with fuel and burn. If the air is heated up, it basically expands, making it less dense with oxygen. The less oxygen in the cylinder, the less fuel you can burn, the less power your going to make. The more oxygen, more fuel, more power.
Quality boost, not just high boost.
But you also can't throw a 50 trim on and not worry about knock just because it's a cooler charge. You need the fuel system that can support it. Your moving more air; More air, more fuel. If not your looking at a lean condition that can lead to knock as well.
There are four biggies that lead to knock;
1. Too low of octane fuel
2. Timing being advanced too much
3. High temperatures
4. Lean fuel mixture
You need to keep all of those variables in balance. If one goes up or down you can adjust for it, to some degree, with the other three.
I hope I make some kind of sense.

To be honest with you Turbolarry, I can't wait to get back from Iraq and see how this 50 Trim feels. You do know that I'm talking about a non-ball-bearing 50 Trim? I know that there are those who are "yea" and "nay" about non-BB turbos but like I said, I couldn't let a $600, non-BB, 50 Trim slip through my fingers when I've seen ball-bearing 50 Trim turbo kits sold around the $3K range. Give or take a few dollars.

This is what I plan on running with it:
Engine Runup meth kit
Tial 44mm V-band wastegate
DNP tubular T3/T4 turbo flange exhaust manifold
Forge UNOS MBC
Forge UNOS RS BOV
780cc injectors
255lph fuel pump
Forced Performance 280 plus Comp cams
BR LICP
ARP head studs

All for a grand total of around $3000. I'd pay nearly this amount if purchasing a ball-bearing 50 Trim turbo kit ALONE!

I'm going to have to run untuned for a short while until Dynoflash pays another visit to Texas.

To the guy above, if you get that kit for VERY cheap, send it out to get rebuilt with a BB center cart. Believe me it helps a LOT. You cannot go wrong with this turbo otherwise. It will make the most WHP on pure pump gas.


You also cannot look at 20PSI and think it is the same accross the board. You must also look at CFM's. Kinda like volts and amps.

I understand about getting a ball-bearing center will help. Who/Where can I get that done?
