My turbo that will hopefully propel me into the 500's
 

Well I ended up going bdc hbp and a t70 instead of going street port and t61. Sold the t61 and bought this bad boy :) Got it locally from a guy that bought one and never installed it. (sorry bobybeach) :) It's a Masterpower t70 with polished compressor housing, .96 tang hotside, ceramic coated turbine, ceramic coated ssauc manifold and tial 40mm wastegate. Can't deside wether or not to upgrade my microtech lt10s to a 3bar or only shoot for 20psi. You guys think 20psi is enough for the 500hp mark on a hbp or should I go with the 3bar and up the boost?

I think you can do 500 rwhp with 20 psi and a 1/2 bridge on that thing.

Man I hope so! I just found out how much it is for the 3bar map sensor upgrade plus the time it takes to send it back to them in australia. I mean if I have to I will get it but would rather not, lol.

same setup i'm installing now

the 3 bar setup would probably be nice to have but if you are only planning on pushing to 20PSI then the LT8s is capable of that. i'm going to have mine converted to 3 bar in the near future to be sure i can take advantage of the methanol and also to be sure i get it over the 500WHP mark. my ECU has to go back anyways to have it converted to a ign cut for the 2 step anyways.

You can, I did 480@19psi..boost leaking, heat soaking, you name it!

Damn, you really stepped up your game, both on the engine porting and turbo sizing. Plus, you've got all the polished/coated goodies as well, yum! I agree that 500 at 20 psi shouldn't be a stretch for this setup if everything is in order :icon_tup:

what size turbo you running now?
gona bring it out to the dallas cannonball run next month?

Clinton, are you lost? We never see SingleTurboRx7 in the Single Turbo section :lol: :MissileSm

I think I'll go ahead and keep it at 20psi and then later on if I "need" more power I'll go with the 3bar map sensor. Thats interesting how you have to send your mt off for the 2step. I thought they came with it? Or is it that it doesn't use ign cut for two step? So what does it use? fuel cut.

Thanks man, yeah I desided to go all out this time. After having a friend mess up one of my plates durring some porting and another iron having messed up tension bolt threads I desided to do this right. I bought three s5 irons and have them at bdc right now for the hbp. Yeah can't wait to see this thing together it's been a year almost since it was up and running last but it only had 350rwhp and nastyness under the hood now everything is either powder coated or ceramic coated so the bling is going to be intense :D The turbo is no 500r but I think I can live with this one.

Thanks for chiming in, I know you had this setup before so I always like to here from you and the results you had. I know you had a bigger exhaust side than me (I've got a .96) so I'm sure the results will be differant because of this, but how much is the question. Did you use a log style manifold for the turbo? Also what size wastegate did you use? Thanks again for the info.

edit: also just a general question about this setup. If I have a 12 and a 5lb spring should I use those combined to reach 17 for daily driving and 20 for high boost? I guess what I'm asking is a 17lb spring rate best for 17-20psi or would only the 12 or only the 5 be better? Doubt the 5 would be good but maybe the 12lb alone would have better effects on boost? Thanks again for the input guys.

if your serious about running 17psi daily then go for the dual spring action but you'll be fine running the 12psi spring. you'll be able to use a boost controller to get over 20 no problem.

i wouldn't compare this turbo to the 500r, it's going to flow a bit more. this also the same turbo i have on my large streetport/ half bridgie TII setup :D mine is a Q-trim 1.0. you should see 15 - 17psi around 4800rpms... only about 400rpms slower spool than a 500r on a stock port REW.... yes im serious. your half bridge will helps spool that monster like crazy. ENJOY!

I just now found this section...seems fitting though

damn, sounds like fun :) Thats really the hole reason I went this route was because of the great things i've heard about hbp's and the great spool on larger turbos that they can produce. So what kind of power are you seeing with your setup and on how much boost?

I have the MP GT45 turbo and there is a possibility I can make it.

I was using the 1.15 turbine housing, so Im sure you I might hit boost slightly quicker. I was hitting 1 bar around 4200rpm(texas heat). I did use the HKS log manifold with and HKS standard wastegate. Around 5500rpm it is a beast!

Also the 12psi spring will work just fine for 20psi. That is what I was using.

awesome thanks man! Do you think you where making more hp because of the bigger turbine? I know the .96 will spool faster but I know the 1.15 flows more thus probably having a possitive effect on hp up top. Thanks again for the info, can't wait to run some of the little boys here in town, lol.

Well not directly more HP because of the larger housing but, it sure did support it well with the amount of exhaust flow from the HBP. I know it helps alot up top. you will kill all with this combo !

NICE!!!!!! I have a friend with a turbo'd 240sx (18g) and another with an evo (16g with alky) and a few with crazy honda swap/gutted rides and they all think they're going to spank me on the track but thats just cause they don't know anything about a turbo'd 13b :D So how is that bp and gt45 treating you?

Well I havent gotten to really push the car yet, I will though in like 3 weeks!

nice, i am curious as to the difference between the T70 and GT45... i won't have my setup broken in for another little while. i work on way too many customer cars to get anything done on mine :(

but it will pull like all hell i am sure of this :D

my personal experience on this setup comes from tuning my friends FC (hbp, T70, rb dual exhaust, etc..) that thing pulled like a fuggin beast to me.. and i drive 400+hp FD's every day. that car made them feel sloooow hahaha

it did something like 330 - 350rwhp @ 10psi untuned. never got to dyno it after the tune and 15psi. he had 285's in the rear and it would lite them up on the highway ;)

i love reading this stuff!!
makes me want to get my car done NOW!
no BP though:(
just a streetport:/

fuel cut unfortunately, yes.

That does suck! I wanted to use the 2step on mine as well for those times at the track but thought you could use either or? How much is it to change this?

Lots of people get killer results on streetports so really you got nothing to worry about. Good luck with your setup when you finally do get it done, post it up! Would love to see it.

Man this is nothing but good news :D I love hearing it from peoples experiances and from what you discribed I will be nothing short of amazed! I'm going to send my ecu off to brian to have him put a rough tune on it and then will be driving up to get it tuned as soon as I'm done with everything. Maybe at that time I'll dyno it and have some more numbers to support this increasingly popular setup.

Good luck man! I bet that thing is going to be stupid! How does that bp feel as far as driveability? I saw a video of it ideling and it sounded mean as all hell! Thats where the wicked brap brap brap comes from. A hbp sounds so tame compared to them.

seeing as how just about anything they have to change in the ECU it is generally about $200 plus shipping to and from. :(

contemplating just ordering another with the features i need and just selling mine but i'm willing to bet they still charge me an arm and part of a leg for the 2 simple changes i need done.

Yeah I hear that. why don't they have a place in America again?

looks like it will be March 24th

only large scale companies can afford to have several supply factories, Microtech is still a small company and only has distributors in the US and will probably never have a central location here.

I'm actually strongly thinking about selling my lt10s and going to a power fc using the adapter kit that banzai racing makes. I believe it already comes with the 3 bar map and everything if you get the kit through them.

yuck.. i still hate the PFC but i guess it takes time to get used to. i am still stuck on how easy it is to work with the microtech in tuning though. i just hate being stuck with the PFC's block memory tuning, sure with any fine tuning you have to use it but what's nice about the microtech is even with a rough LOAD map tune it is still 95% as close to a fine tune already.

straight out the wood works, check it. I got everything to rock.

Damn!!!!!!!!!! You gotta get rid of that little ass turbo and go to something bigger man, lol. What are those dual tial 38's? Very nice man can't wait to here your numbers with that turbo. Time to get that hotside ceramic coated :)




I've never really messed around with a pfc so I can't say much for them I just know that most people don't like or at least don't tune them on a regular basis. Most of the tuners I know of would rather tune on haltech or pfc. I still haven't made my decision yet. The power fc can get pretty expensive with the harness adapter, good stock harness witch on a second gen is hard to come by, power fc, commander and datalogit I would probably have to put out a ton of money even after selling the microtech.

Yeah I think I might need a bigger turbo, I hope I don't caught with it in the Turbo Street class :) Those are dual Tial 38mm...I do plan something for the hotside, for the time being i'll use a blanket.

If you're going to run anywhere near the limit on the boost sensor, why have it fly blind if it ever spikes?
Doesnt matter if you're going to run that much boost on purpose, but its nice to have your ECU know whats going on.

lol as one george bush to another you are absolutely right and I have pretty much the same thread on teamfc3s.org and I had a guy write the same thing you did and it really made me change my mind. I will go ahead and get the 3bar map for this exact reason. Thanks for the input.


You better get vids of when you drag this thingin turbo street class or I'm going to have to have to stick brian on you....speaking of witch he's always got a camera recording something. Tell him to go so he can record it and post it up on here. Good luck!

I’m running 23-24psi on my 20psi map. I guess it’s not ideal but it can be done, just allow a timing and fuel map for max psi setting on your 20psi load map.

lets be realistic your ether cursing under vacuum or a gentle squeeze of boost to over take or your punching wot at max psi, so there’s really no need to have load settings that are super accurate in between.

Just my opinion though, I guess its all relative to how much money you want to throw at the car vs. measured gains.

uuuhhhhmm it seems like you me , slammedblk7 are reaching for high hp notes....looks nice where did you get your heat blanket at

Man Nowadays I dont know what the hell im shooting for!!! whatever 30psi gets me!

the turbo blanket came from gothamracing and is very good quality. Probably one of the best quality blankets I've seen.

Well to tell you the truth I would rather not spend to much more money on it and really don't want to wait the amount of time it takes to send the unit to australia and get it back. You have an interesting suggesting there and will ask the guy tuning it if he would feel comfortable doing that. Thanks for the info boby and again sorry I didn't get the t70 from you, just found a killer deal in town.


lol, I can't wait to see the numbers on that! Hopefully I see that car when I go to grand prarie to have brian tune my car.

Yeah I should have it tuned/dyno'd by then.

you and me both man ;) i'm starting at 25psi and going up!

so what do you guys have in the motor that will enable yall to go 30+ psi

Liquid Schwartz. :D

B

lol, and the turbo must breath in parrie air to mix with that liquid shwartz :)

Cant wait to see numbers and times :) , that turbo looks so very promising.

Unfortunalty Everyone who has installed it in the past hasnt runned it hard. then parts out or upgrades or takes a break.

Hope someone runs the 25 psi :) and mucho videos.

And slammedblk7 , Cant wait to see your tune with the new manifold . Maybe you posted, but when are you going to get retuned ? and videos :) also.
