Hey guyss...I've started saving up a decent amount of loot to continue modding up my 8...but now i'm stuck about what I should do...I plan on getting the Greddy bolt on turbo with the Mazsport Greddy turbo upgrade and the Interceptor-X ems...however I don't know whether or not I should do some internal work first such as headers, fuel injectors, intake, pulleys...or even go with my suspension mods first...if I were to start with the suspension I would get the HKS Hipermax II setup...and if I start off with the turbo should I change the intake system to another aftermarket system such as the HKS racing suction intake?? What should I do guyss =\ i

You need to study up a bit first before you do any mods. Headers, injectors and intakes are not considered "internal work". If you're getting a turbo kit then headers and intakes would be stupid. Turbo kits come with the exhaust manifold to mount the turbo and also come with the intake to direct air to the turbo.

If you are not even familiar with the parts of the turbo kit you should not even consider a Greddy kit. Also you should have money set aside for far more than kit itself, you need money for the kit, the gauges, tuning, installation, etc. Not to mention, if you blow the engine, do you have an extra $3K for the new engine.

About ten years ago, I spent a ton of money on just about every bolt on imaginable for my 94 Mustang Cobra.

My best friend, who had a 93 LX spent about the same amount of money on a ATI procharger. Needless to say, his car was faster in every way. Made me wish I would have just gotten the supercharger to start with.

I say, go with the turbo and the the upgrades. Then, spend money on some good tires/wheels. RX 8's are find handling cars straight from the factory, so I can't see spending much money on suspension components, with the exception of some lowering springs.

Turbos should be the last thing to think about. You need suspension, exhaust, midpipe, wheels and tires. Then make sure you have enough money for all the supporting mods like tuning, clutch, guages, and install. Then you can think about the turbo but dont forget making sure to have extra money aside for unforseen costs.

Please don't criticize my knowledge...i may not be the president for RE-Amemiya but I'm also not a newbie...been on this forum since '04 studying up on this...I think 3 years is enough...right now i have the rp supercat with the borla catback system...along with the rp short shifter...and I got some pretty good rubber on right now: Toyo Proxes 4...I understand that the items I mentioned aren't close to all the internal modifications that this car has...I'm just wondering what would be best in the end for me...I don't want to purchase a forced induction product and destroying the life of the engine more than I already would be...and the reason I mentioned another intake is because I've heard that the Greddy system's intake system sucks @$$...and I know that there are a lot of expenses along with the turbo...I have a way to get all these parts wholesale price as long as they are easily available...I can get the Greddy Turbo kit itself for a about 2K...and I could get the HKS coilovers I mentioned above for about 850 not including dampers and such...advice is what i want...not criticism...thanks for the advice mike1234a and HCTR154

Time has nothing to do with it. I've been on the forum for 3 months now. If you understood how a turbo system works and what the kit includes you wouldn't be asking if you should get an header and intake when you're planning to turbo charge. You did say "I plan on getting the Greddy bolt on turbo with the Mazsport Greddy turbo upgrade and the Interceptor-X ems".

When you state "and the reason I mentioned another intake is because I've heard that the Greddy system's intake system sucks @$$" are you talking about the filter itself??? Your first post talks about considering a HKS racing suction intake. If you're just looking to replace the filter then buy the filter, don't spend hundreds of dollars for the racing suction kit and expect it to bolt together with a GReddy turbo kit.

True you are correct...thats why I ask for advice because time doesn't mean everything...I will just do what I feel is fine then...thanks I guess...

Nobody really offers an aftermarket air intake for the Greddy system. It is an exposed mushroom intake in the engine bay. When we were tuning the kit, we found that at idle (say at a stoplight, but while we were in the shop) the intake temps shot up quite high. I finally had my mechanic fashion one for me. If you plan on trying to go more than 300 whp (about 9-10 psi) then upgraded injectors would be smart. Again, i would recommend this kit. For the price of the parts you just mentioned, the Greddy turbo kit, the Mazsport upgrade on the turbo, and the Interceptor X, you would be close to just getting the Mazsport turbo kit, might as well just step up.

Yah...thanks for the heads up...what i was thinking was even after all of the accessories needed for the kit (gauges, boost controller, turbo timer...) I would be spending 6-7K (still cheaper than any of the mazsport kits, and I'm installing it at my buddy's shop so very cheap labor fees if any)...also I'm not looking to be pushing 400rwhp like mazsport states the kits are capable of...I really loved the dyno video on mazsport's website for the greddy kit w/ the interceptor...really shows what it is capable of doing as long as I'm devoted to making it work right...I'm also pretty intrigued by the new 4th kit coming out by mazsport...still got a little bit to wait though...I guess my options are gonna be get the greddy with all the extras, get a mazsport kit and run on low psi to be running at my desired level, or wait for the 4th kit

mazsport makes an aftermarket cai for the greedy turbo. you can order it when you get your upgrade.

You just have to wonder though at that point why not get the better kit with all the money you spend. The Greddy turbo upgrade is really for somebody who already has the kit currently, and wants to upgrade it. But if you are going to get the Greddy kit, and the Interceptor, and the Mazsport Greddy Turbo upgrade, and probably the upgraded hoses, etc At that point you are probably over $5K, you might as well save up some more and get the Mazsport kit that already has a bigger turbo, a upgraded fuel system for the turbo, etc.

Previously there was a poster on the board (Manuel, RX8PR), who tuned the daylights out of the stock Greddy system, and at around 12-13 psi he was getting around 310 whp. Even then he had to weld the internal wastgate shut, fab his own external wastegate, not to mention at say 325 whp+ you will need to upgrade the fuel system, probably a bigger IC setup, bigger injectors, etc. Why not just go for the Mazsport and get it all...rather than dealing piecemeal with every component and possibly having some failure down the line.

great and accurate post. not to mention fuel pump.

i wonder if the fact that his screen name is GeTcRuNk has anything to do with people not taking him seriously

GeTcRuNk

touche BlueRenesis loll...great advice fanman...and I also heard that there is literally no risk of blowing the motor with the mazsport turbos cause of the t4s...this is definitely making me lean towards their turbo kit...right now the 8 is my daily driver and I commute 200 miles back and forth from my school in massachusetts to jersey every once and a while...I'll probably wait till I get myself a beater and just do this whole project the right way...

LabDad

Statements like this lead me to believe you have no clue when it comes to turbocharging. It doesn't matter what turbo you have a poor tune can damage your motor. The Mazsport kits are well respected because they come with a safe conservative tune.

PM me and explain to me how a turbocharger works and some of the benefits and risks associated with it (I want to understand what you know, or think you know). I'll answer questions, fill in the blanks and give you some links to read. Seriously, if you want to learn more, PM me and I'll take the time to tell you or at least point you in the right direction.

GeTcRuNk

Thanks a lot...i'll def PM if I have any concerns...what I was trying to say is that with many of the other turbo kits, even when professionally tuned and pieced together correctly...there is still a good chance of blowing the motor (on a dyno and such...)...If I were to get the mazsport kit...I wouldn't need to run on a higher psi like I would want to with the greddy kit...5-9 psi compared to 5.5-13.5 psi(like in the dynovideo on mazsports website)...if I'm thinking wrong...please correct me...thanks again

BlueRenesis82

the psi doesnt have a whole lot to do with the risk of blowing your motor. it has more to do with if you run the mixture lean, or detonate

Fanman

Yeah the engine doesn't care if it is a big turbo blowing 6-7 psi through it, or a small turbo running 13 psi. air is air, cfm is cfm. In general running a ton of psi might affect the turbo life moreso than the engine running a bigger turbo at lower psi. A few Greddy turbos have had seal leaks and needed to be rebuilt.
