Will this make 300tq?

[FRslimmyjim]

Hey Guys,
So i have been reading a lot and made some important decisions about my project. This car is my daily driver and I want to start off by thanking Glowryder for helping me so much in my other post http://www.dsmtuners.com/forums/420a-bolt-tech/438543-can-i-reach-400whp.html. I owe you big time. Thank you so much.

Okay back to business. I have decided that I am going with Megasquirt 3 w/ the expansion board. I am going to get pte 660cc injectors that are high impedance injectors which is what megasquirt 3 uses. I have a brand new precision 6031E 72 trim turbo with a .43 hotside which I will be putting at 11psi with a manual boost controller. I almost have a completely built low compression (8.6-1) engine. Only thing is missing is cam gears and stage 2 crower cams. I don't have an LSD or eibach springs yet which i will be getting soon but in the mean time I just want to install the megasquirt to get rid of the stock injectors and the vortech 12:1 FMU. I have a afpr. I have brand new tires and all new synthetic oil, trans fluid, all new ball joints and bearings and tie rod ends. 4 wheel alignment with chart. Need to get a camber kit for the back right since it is .4 off.

Do you guys think this will get me 300tq?? Is there anything I am missing? I have tunerstudio already as well. I am planning to do this right after the new year begins so I still have time to keep reading up on the megasquirt. I have been reading till my eyes bleed haha. Once I get the megasquirt in a dialed up i will be doing all the mods to get the power to the ground.
Thanks guys

NP, glad I could help.

Congrats on MS3! im jelous!

" I am going to get pte 660cc injectors that are high impedance injectors which is what megasquirt 3 uses." If i recall, you can get the Injector board on the MS3, and run low Impedance. This will be nice if you run larger injectors, and it will also let you use seqential injection, it has advantages over bach fire, which is what youll be using on a"stock" MS setup. Just food for thought, theres nothing wrong with your 660s.

Sounds like your on the right path for your goal. Keep reading, and try and find a MSQ on symtech site that matches your build the closest. Load it onto tuner studio and just kinda look whats going on. There is great documentation out there, so i think your going to do well. Get that LSD
Other things id suggest that you may have already done:
Front motor mount bolt mod
Poly motor mounts
Clutch?
For MS I prefer Inovate, ive had AEM, and i like the Inovate better.
If you havent ordered the MS, id think about adding : seqential (requires cam sync mod), Launch control, Tacho, logging (for EGT and other guages). there also more options, but those are the ones I like/use/would like to have.
And of course crank scraper/Baffle setup

i think youll hit your goal. IF not at 11 Psi, Im confident it would be before 15 Psi. sounds like a solid build. GL! and keep us posted!

I'm not a turbo guru but a .43 hotside sounds pretty small to me. Is it?

EDIT: ASSuming that is a somewhat small hotside, is it small to keep it more responsive with the 72mm compressor?

 

[glowryder]

Good questions, im not sure. It does seem small, but i think its equiv to an sc61?

 

[FRslimmyjim]

It is small but I have a friend on DSM-Addiction.com (Its an awesome website you guys should check it out. I have the same name there as well so hit me up if you register) and he had the same turbo and it comes with a .63 hotside and he said it wasn't as responsive as he would have liked and this is my daily driver so i went smaller. I am very glad i did too. It spools so nicely its absolutely perfect. I recommend it to anyone who is looking for a turbo without the HUGE price tag of a crazy turbo. My turbo is very close to the sc61 but it is a 72mm not a 61mm.

I have all the mounts done and I was planning to get the innovative wideband. I heard great things about it and I want to be the safest possible with my baby.

Front mount bolt mod?? What is that? I have never heard of it before.

I was going to get a crank scraper as well. And i have a south bend clutch good for 700hp. (didn't want to skimp out on the clutch due to not wanting to change it again haha). I am also definitely getting the LSD as well before I start to push this car.

I haven't bought the megasquirt or the injectors yet so tell me if i should change this. This is the reason i haven't bought anything yet. I want to get the best for my baby. She is my life. I have put my blood, sweat, and tears into my baby and I am not going to mess things up but im still doing all this work myself because this is my passion and I will do this.

So if I go low impedence injectors, that will make me able to go bigger? I will be pushing this car hard one day so I want room to work with.

I can't find an answer for this but with the megasquirt 3 it comes with the expansion board and it says i can run 8 injectors. Is it possible to run 4 of them off of boost like the portfueler? I haven't seen it done before and im thinking it will get me or someone some good power and driveability. Idk, its just a thought.

Oh and im also getting a egt gauge. Is the a specific brand everyone uses that is great??

Thanks for all the help!!

 

[glowryder]

No reason to run 8 injectors with the MS's tuning ability.

The Seqential alows you to idle better, as well as gives you more efficent fueling. It also allows you to run LOW Z injectors. The card itself wont allow you to runn bigger, as it will run bigger ones without the card just fine. But the bigger you go, the harder idle is to tune. 1000cc starts to get into the dificult idle range.. thats where seqential comes in. Makes it nicer and a little esiaer to control them at low pulse widths. IMO, might as well get the best MS3..i wish i would have.. im stick with MS2e RIGHT NOW.

Search front bolt mod, youll find it.

I use autometer for my guages

 

[FRslimmyjim]

Okay. I looked up the front mount bolt and i did that when I was doing the mounts myself haha. It didn't make sense to have a small bolt there so I just decided to put a bigger one in. Glad that is what i was supposed to do haha.

Well by the sounds of it i'm going to go low impedance injectors now. Should I go with 660cc or 880cc injectors? I don't want all the power in the world right now but I also don't want to buy two sets of injectors. I still want to get 400 or so out of it one day. Is there any side affects if I go with the 880cc instead of the 660cc.

 

[glowryder]

With MS, there shouldnt be a side effect of going larger, you simply wont use it all. the down side is larger means more dificult to idle, however, 880's will give you great overhead for expansion and idle shouldnt be an issue at all. I think its a better choice. keep in mind youl need to get the peak and hold board for your MS3, and cam sync if you choose to go seqential.

 

[FRslimmyjim]

Okay. I am definitely going to go sequential just because i want to do everything perfectly and i want the best. So i need the peak and hold board and cam sync. Is there anything else i should get? Maybe anything specific to 420a engines? I am so nervous that I am forgetting stuff and i just want this to be right.

 

[glowryder]

as far as MS, i think your covered.

 

[FRslimmyjim]

Okay sweet. Thank you so much man

 

[glowryder]

Also, you going LSD? that will be huge for you..

 

[FRslimmyjim]

Yea i am. Is there one you recommend the most? Keep in mind im not made of money haha

 

[glowryder]

quaife. Period. Yes they are expensive, but i dont think anyone on the 420a had busted one. They are worth it. To me this is the one thing i try to hammer into people doing a build. this wont give you power, it will simply put your power down wayyy better.

 

[FRslimmyjim]

Okay thanks ma. I appreciate you man, thanks for all the help. If there is anything you think im missing please let me know. Thanks
