NA to NA-T guide and Information...?

[kmn5]

Hi all.
I know Dave H is a busy guy, I've sent him some emails and pm's but never got a responce.
Anyone know if he has a website and when his parts are "Offically" for sale??
I've heard of a few people already using his manifold already.
I want to add one to a SC300 2JZGE

Also wondering if the downpipe is the same for the NA supra as the SC300.
Thanks
ken

Ok Folks I got my NA-T up and running, just need to finish up the intercooler pipings. However my car sounds funny. When you get to about 0 pis, and shift, it makes a fluttering sounds.


my setup:
TO4E-60 - $620 used
Fmax manifold- $820 new
intercooler pips - $20 (hookup from Mike) 3 u bends
S-afc - $320 new
VPC- $500 new
oil lines- $45 new
oil union bolt-$35 new
TT-intercooler- Free(hookup from in-laws)
TT-Fuel pump- $80 use
440 injectors- $330 ( from Dave H)
welding works-$200 service

in total I spent about $3300

congrats moua4c, glad to hear it. maybe u could help out thomsoncharm, he seems to be having a hard time getting his na-t done. been close to 3 yrs. i believe.

[moua4c]

Thanks Kdirty130.

Wow, that is a long time to have the car down.. Did my in 10 days, could of finished it in less, but only work on it after work. I got some help from Mike.

oh yeah, just in case you folks wanted to know. For the VPC chips, I can copy them and burn new chips. It's pretty simple.

I use my working 550 mkIII and burn a copy for AC, Superwild. Now he got his car running. It's been down for 7 months.

[ThomsonCharm]

No No No its only been one year and about 12 months of that one year are me waiting on parts.

moua4c: how hard was it to wire in the VPC and the AFC?? im planning on running AFCII.. so i was just wondering what u used to wire it.. solder? electric Tape? wire caps? and for the oil return line.. what was the easiest way for you to do this.. im thinking about lifting the engine out so i can take the oil pan out and drill holes and then clean it out.. but thats just me... Are you using stock ignition?


Thanks
Flipn

[moua4c]

Flipn: Wiring the AFC & VPC was easy. Just follow the directions. All that is required is the rpm signal, MAf signal, throtal signal, power,ground. It was pretty easy.

As for the oil return, there is a little hole like section which I drill. You could go to Home Depo and get a drill and tap set. I just reach in with a small electric drill and go to work on it. At the same time I use a vacume to pick up the shavings.
When you drill go slow, and use a lightly push and pull action.

[Flipn]

Hmm... I was thinking about pulling the motor out so i can take the lower pan out.... I still might do that.. I am just looking for an easier way to do it...

You still have the Stock Headgasket right??


Flipn-

[moua4c]

Yep, stock head gasket. Boosting 7lb for now, and venting to atmostphere, it's very loud.. Im thinking about ventting it back to the exhaust pipe.

I'll try 12 lb in the future, after I get some 550cc.

[RabidChild]

How about posting some NA-T engine shots. I'd like to see how everyone routed their intercooler/intake piping with the stock intake manifold.

[BigWillyC]

I am about to get a 5-speed sc300 and turboing it is a must. No ifs ands or buts about it. Here is what I know/picked up along the way...

Basically you need to 3mm head gasket to lower the compression ratio to 8.5:1 is this correct? Then throw some ARP head studs in there to clap that shit down!!

With that done you need to look at the fuel system. I have a TT pump which should be pretty good rewired. I would like to go with at least 550cc injectors maybe 660's. Therefore a VPC is the way to go if you can find them.... I have a turbo eclipse and I am running 660's right now so I can steal those from the car maybe if they clip up the same.

I personally would like to go lager than a 60-1 or all other T4 turbos. I like the idea of a T-66 actaully... I have a 57 trim turbo on my eclipse and the "lag" doesn't bother me.

Turbo supras have oil squirters. Has anyone tore appart a n/a block after they turboed it and noticed anything bad under the pistons? If it isn't a problem then I am not too worried. Just get a air/air oil cooler to keep those temps down?

IC pipes and all that is easy. I and confident I can take care of that on my own. That and having an exhuast shop build a downpipe and most of the exhaust. How good is the NA fuel pressure regulator? Should it be replaced with a adjustable unit?

That is all I can think of. Except what do all these kits use to retard timing under boost? I don't know for sure how the N/A's do timing but at WOT you would *like* to be at around 20 degrees advanced... anything really high is no good. You know how the honda crowd need the FMU or whatever... how is this solved IF this is in fact a problem?

If I am incorrect on any of this please correct me. I am new to this world and want something a lil more reliable that my DSM (damn shitty motors)

Thanks for the *lengthy* space

sup fellas, have question on t-88.
i love greddy products but they don't make a turbo kit for my na, so my question is, toyomoto, fmax, dave h kit, etc which of these people sale the best parts to put a t-88 in my na?
from my search i believe dave's kit can bolt on any turbo, is this correct.
thanxs fellas as always,

darkmethod----------------------------------

[Flipn]

T-88 is a HUGE turbo.. you might not have enough clearance from the distributor... A T-88 isn't really a street turbo... So i donno if you will like it that much.. way way too much lag. but if u want a manifold for it.. you can use the DaveH manifold BUT you will need a new flange.. the DaveH manifold uses a 3 bolt pattern and i think the T-88 uses a 4 bolt pattern.. You can always call SP for a manifold just make sure it clears the distributor..


just my .02

[DARKMETHOD- SUPRA SITH]

thanx flipn----

[Verge]

a t88 is huge

[GreenPunkBlood]

i have an 87 NA, yeah a 7M yah u mk4 duds might have some clue of what that is. anyways, i need a turbo.. i herd you could run a turbo on a 7M-GE with stock internals. is this correct? also how much boost do you think i can run. Im hoping 1-1.5 bar. yeah im gonna get a MHG for that..

[BigWillyC]

My inital plan was to run a VPC with 550's but that is the biggest you can get with high impedance injectors (gay), then probally upgrade to 600 something injectors later on. Well that ain't gonna happen now since the vpc doen't have chips bigger than 550's and injectors don't exist. Sooooooooo for those who are running bigger than 550's on your na/t, what fuel controller are you using and all? That and do you just put resistors in or????

Thanks

Will

[ThomsonCharm]

It is ok to use the VPC with the 550 cc injectors as long as you have something to fine tune everything out if you are using bigger injectors like for example a Apexi S-AFC, Greddy Emanage, or a HKS AFR.

[BigWillyC]

What about injecotrs themselves? there are 2 types of injectors low and high impedance (peak-hold and saturated) High impedance injectors don't get any bigger than 550's as per RC's website. So in order to use bigger injectors you must switch to low impedance (peak-hold) injectors. What is the trick to doing this? I remember hearing something about using injector boxes or something like that but what about putting in inline resistors???

Yes the injectors will low impedance for the 680s like I am running and Yes you do need a solenoid resistor of some sort. You have the option to either get a MKIV Twin Turbo Solenoid Resistor, and MK3 Turbo Solenoid Resistor, or I have actually seen some use 3 DSM Solenoid Resistors.

Hope this helps.

[BigWillyC]

Ok so how is this done? I belive the DSM solenoid resistor pack is the silver box on the firewall. I have access to tones of those buthow do you wire it in? I might just get a tt resistor pack cause that soulds the eaisest route. I didn't plan on using a dual piggy-back system but it looks like I must. Besides I havea s-afc laying around. I will have top PM you here in a month or 2 when I get it all set up.. right now I am just aquireing parts that I need.

Here's a list of my parts that already came in but have not been installed. Before my shop starts the installed I was wondering if I'm missing any parts. I'm planning to push 400rwhp.

Garrett t 60-1 turbocharger ar.70
Turbonetics cast iron manifold(original founder of toyomoto manifold)
Turbonetics wastegate that goes w/ the manifold
Steel exhaust flange w/ gasket
Walbro Fuel pump
Hks ssq bov
RC Engineering 550 injectors x6
Greddy E-manage
Stock TT Headgasket
Blitz Nur spec Exhaust
TT intercooler
And all the nuts and bolts and oil and return lines

The only thing I could think of that I'm missing is a Fuel Rail. Can I use my stock Fuel rail w/ the 550 injectors if I'm planning on pushing 400rwhp?

are you going to stack 2 tt headgaskets?
what about apr head bolts?

[mkivsj]

wow...i looked at the beginning of this thread a while back ago i asked how to turbo my car...and the next thing you ... know my car has forced induction..wow time flys

[Rocky28072]

Well I guess since my car is under the knife right now I might as well post what setup I'm going with. I'm having Brad Mayo at Speed Innovations do the install and I should have it back fairly soon. I'm auto so I'm kinda limited in power until I upgrade my trans.

Here's the list:

Precision Turbo PTE 44 turbo .60a/r
Dave H's cast manifold
Dave H's 3" shorty dp
Dave H's w/g dump tube
6 Delphi 525cc top feed high imp injectors
Walboro GSS341 Fuel Pump
Stock Supra TT SMIC
HKS SSQV bov
Tial 40mm w/g
Sound Peformance N/A-T h/g (double stacked TT h/g's)
ARP head studs
HKS VPC
Apexi S-AFC
Greddy Profec B spec 2 EBC
Greddy Turbo Timer
Greddy Boost and EGT gauges
B&M Tranny cooler
Custom IC piping, midpipe, and oil lines done by Speed Innovations

In all, I've spent about $4500 in parts plus installation.

I could have spent less and been boosted sooner, but if I'm going to do this once, I might as well do it all at the same time. I will post dyno numbers and overall evaluation of the car when I get it back sometime next week or the following week.
