Turbo prepping
 

Hey guys I finally gave up the 1.6 turbo and picked up a 1.8 from a 2000 NB. I'm slowly gathering parts to turbo the engine. Any other parts should be included to turbo this stock motor?

The parts I have so far are:

Engine Management:
Megasquirt PNPv2

Fueling:
Injector Dynamics 1000cc
Deatschwerks 200 fuel pump
Stock FPR (should I use an aftermarket?)

Electronics:
Innovate mtx-l wideband
Autometer boost gauge
Apexi AVCR electronic boost controller
Toyota cops (wired for a 1.6)

Drivetrain:
ACT clutch
Resurfaced Stock 1.8 clutch
94 driveshaft, axles, differential (open), 96 transmission.

Engine:
00' 1.8 head and block
FM swap kit
arp head studs
Custom intake manifold (hellafab)
Fab 9 solid motor mounts

Turbo:
BorgWarner EFR 6758 IWG
Fab9 stage 1 intercooler
Ebay IC piping
Turbosmart BOV
Trackspeed Engineering stud kit

Exhaust:
3" full exhauat
Equal length header turbo manifold (hellafab), bottom mount.

Cooling:
KOYO radiator (r series) from fab9
Custom coolant reroute (followed the write up from rev limiter)
Ebay slim fans w/shroud


Misc:
Fel pro Headgasket Kit (hahaha)
Fel pro rear main seal
Rotella t6 oil
Generic synthetic trans and diff oil
Generic oil filter
Generic fuel filter
BKR7E NGK Iridium spark plugs
Crankshaft bolt
Woodruff key

Is it necessary for a lighter flywheel? What about a SuperMiata HB? Do I really need to upgrade the fuel rail or fuel pressure regulator? Do I need to run a coolant temp, oil temp gauge, or anything else?

My power goal is to hit 250rwhp. I've been reading anything pass that is a higher chance of blowing something.

imo, 250Whp is already running on borrowed time without rods and a six speed.

No, a lightweight flywheel is not "needed"
No, you do not need an upgraded fuel rail or FPR.

Set up megasquirt to alert you if temps get too high, if you don't want gauges.

Thank you. Should I run the 1.8 throttle body with the tps? I've read tuning with the tps is better for fine tuning. Do the wires need to be soldered on the ecu, to enable the ecu?

I certainly value my TPS sensor while tuning...


Uh, wut?

Disregard the last part. I was referring to the megasquirt haha.

Definately use 1.8 TPS.

EFR is awfully big without built motor. Transmission will be unhappy at some point (if you go higher). Open diff is sub-optimal.

Megasquirt can control boost. No need for Apexi. (but if it works reliably it isn't a terrible addition)

Not a terrible build list. It's pretty terrifying when looking at the full list of stuff to be done before turbo.

Your 99 engine has no FPR. It is in the fuel tank.
The 1.6 FPR will be unusable on the '99.

The EFR will be very tough to keep from killing the rods if they are stock.

Ah I see. I'm using the AVCR, only because I got it for a good deal awhile back. I'm probably not going to be playing with the megasquirt as much. After loading a base map, getting the tps working, and raising some fuel values, I'll bring it to one of the protuners in Hawaii.

I used the 1.6 fpr (little minature top hat) and bolted to the 99/00 fuel rail when I did the swap on my 92.

As for the rods. Yes they are stock. Let's hope for the best that it doesn't. This car usually sits at home, I bring it out during the weekends or when I am off from work (of course to relieve some stress).

After reading 99mx5 build thread, I'm afraid of blowing something up. lol..

With an EFR 6758 you should be afraid of blowing up the stock motor.

:[

Yeah. An EFR 6758 is way big for a 250whp goal. You'll have a really hard time not popping the motor even on wastegate boost.

250whp on a good tune on a street car is totally reasonable on a stock motor. With that EFR at 8-10 PSI boost you'll be well over 250 whp most likely.

hm, we'll see. I'll keep this thread updated.

Still waiting on a few parts to be shipped, so far I purchased:

Fab9 stage 2 intercooler
Mishimoto oil catch can
Turbosmart bov
Skunk 2 throttle body
Hellafab Race series intake manifold
Hellafab bottom mount turbo manifold
Full 3" exhaust to vibrant muffler
Toda cam gear
Built motor (pending lol)

EFR 6258/6758 owners, I'm using TSE stud kit and I am wondering, what are some solutions to get the nut on the stud? The nut won't fit because it's too tall, and I do not want to grind the turbo. The only solution I could think of is use a generic stud and nut that follows the TSE stud kit or drill the turbo flange to create more room.

Have you gotten this running yet? interested to see what kind of power you are making on that turbo

Not yet. I'm going to be driving it with the stock motor for now. Until I come up with the money for a built motor.

This is how it is looking at the moment. I opted out on the Toda cam gears. I believe it is not needed.

I wonder how comparable this turbo is to my GT3076r, I will be running 7psi off wastegate pressure and aiming for around 225-250 whp. I will be doing rods and pistons after this season.
