Hey guys,

My current stock Evo 8 turbo is developing some shaft play and I’m thinking of upgrading it to an FP turbo. I’ve been looking at the FP Green, FP54 and the FP Green UHF but reading into some forums it seems like an FP Red may be the way to go. I’m mainly just gonna be daily driving my Evo 8 MR and it won’t be seeing much track days since there aren’t many tracks nearby. I also am not looking to make big power but probably somewhere the 400hp+ range. Any recommendations on what turbo I should look into running?

 

I've been looking at the same and the FP54 green BB is what i was leaning towards. From what I have read the red has more top end power and the green has quicker spool. I like quicker spool.

 

Goals and supporting mods are something to consider! If you want as close as stock spool as possible from FP, look at the 71HTA. It's the "+1" over a stock 9 turbo. They tend to lose steam toward redline however, which honestly isn't a big deal for a daily since you'll still make it to around 400 with the nice tune on pump gas. The 71HTA don't take much beyond bolt-ons, just fuel pump and maybe injectors. Step up to green and you'll get some more top end in exchange for a little bit of spool, nothing too noticeable for the power and is my personal choice. Full tilt around 3800-4000 depending on mods. The reds are known to have some noticeable lag over stock, but can reach 500 on e85. Around 4400 spool? These are pretty ballpark figures, they can spool faster if you get BB. (But that's more $$) You'll need to invest in a oil filter feed line to keep them reliable too, beyond other basic supporting mods like injectors, fuel pump, cams, etc. I won't get into black because it doesn't seem like that is what you're looking for, just know that they don't mess around! I've read often that people regret not being honest with themselves and getting the black but I think it's all about goals. I like the low end torque! People have stroked engines too and that makes a difference. The FP HTA Green and FP BB MHI Reds are some of the most reputable turbos on here!

I'm not too familiar with other turbos other than FP, but I'm sure somebody will be happy to fill you in about those as well.

I hope this (really) general information helps. Cheers!

 

Need to know your power goals and how you realistically use the car to recommend a turbo.

 

Quicker spool is what I'd prefer over top end power tbh. Not really looking to make a straight line monster. I was also pretty much leaning towards the FP54 but I guess just reading through some of the other threads got me second guessing.

Thanks for the information, it definitely helped narrowing it down! I think I'm leaning towards the BB FP54 Green despite the higher cost (Just for the sake of reliability). As far as supporting mods to go with the turbo, I'd say I'm looking into a new fuel pump ( Haven't actually checked out what fuel pump I have on the evo since I bought it off the previous owner ) and 1000cc injectors. My Evo already has forged pistons, conrods and pretty much an indestructible T-Case which I'm sure can withstand an FP54 Green. I just wish there were more data out there to compare between all these variations of the FP Greens especially better data for the new UHF Green.

Power wise I'm looking at between 400-500hp and it's mainly just gonna be for the streets ( and the occasional track day ). Not really keen on using E85 on the evo since there aren't many stations near me so just pump gas will suffice.

 

What pistons & rods are recommended for 500? I’m on a conservative tune on stock internals and fp red on pump 91. I want to make more than 400. Some imput advice feedback would be great! Thanks.
GSC2? OEM crank ? OEM or GSC tickers?

 

Bottom end can take 500whp but not more than 550whp from what I know. You should be okay there, but I'd recommend cams for sure. GSC2 are a fan favorite!

 

You can definitely handle a green. The truth of it is, you're probably not going to be able to hit 500 without e85. The reds even have a hard time doing that. But hey! Don't get so caught up on numbers! If you prefer spool over top end, then green sounds like more your style. For a fuel pump, you'll just need a Walbro 255. You could talk to turbo experts to find out the minute differences from recent greens. The variations of the newer greens are all fine lines, pieces cut from the same cloth.

 

My FP/MHI-18k just arrived this week, was gonna do HTA71 or BPT but went with the MHI unit.

 

I ran a green for years with 272 cams, a wally 255 and 850's on speed density with 93 octane and only made 315whp on a mustang dyno. Switched to a red with S3 cams, kiggly beehives, same fuel mods and made 425whp on 93 octane at 23 psi. This was considered a safe tune and to be honest for a weekend driver this is more than enough for me considering I'm not trying to build the block anytime soon. Just keep in mind that you aren't going to be able to slap a green on with fuel mods and make close to 400 on pump. First thing you're honestly going to want to do is have a compression test done and if everything looks good do a little maintenance. ARP Headstuds, throttle body shaft seals and a boost leak test is what I'd start with.

 

N00b question but Will stock pistons / rods / gsc 2 handle good enough for an Fp red or do I need to upgrade my internals besides some bigger cams?

 

You will need to tune it accordingly. To limit torque to keep the stock rods straight.

 

My HTA71 does 450+whp on e85 and spools right now. Best turbo I've ever had.

Edit: saw you changed to no e85.

For 450 on pump, you may need to go to a red. Hopefully you can make a green work.

 

Pretty much all FP turbos (HTA71, green, and up) can max your torque on a stock block. You can make as much power as you want, within reason, as long as you don't mind that lag that comes with it.

 

yeah I miss my fp green, fun fast spooling turbo , with minor bolt one I made 401/352 on a conservative tune. Got the red now on Same bolt on and did 386/350
on pump gas. We don’t have e85 around here
