1991 MR2 Turbo Build - Built motor BIG turbo

[WAT TURBO?]

Picked this sucker up the other day from nashville. Im super excited about it.

1991 MR2 turbo Tbar 5spd

Engine:
ACL bearings
Wiseco pistons (forged alum)
K1 rods
Stock crank
Ported stock head
880cc injectors
HKS 272 cams w/ adjustable cam gears
Jackson racing fabricated intake with BBK 70mm TB
Tubular exhaust manifold
67mm turbo, OBX WG, Greddy adj BOV (soon to be changed)
Trunk mounted IC with dual electric fans and Subaru trunk scoop!!!

Drivetrain:
6puck clutch
SS brake and clutch lines
Drilled/slotted rotors w stock calipers
Some kind of coilovers....?
Tanabe sway bars
Every poly bushing known to man

Interior:
Seats are decent and the dash isnt cracked. The only things missing are the shift boot/knob and the radio. All the lights work as they should.

Exterior:
Some red color that apparently likes to turn pink after 20yrs. Nothing a little glazing wont cure.

[WAT TURBO?]

Fans on the bottom of the intercooler


Jackson racing intake manifold. Needs to be polished...


Anyone know what these connectors go to?




:shock:

[WAT TURBO?]

Subie trunk scoop!!!!!





The only issue with the driveability is the ECU being stock with 880cc injectors. I Want to run megasquirt on it but a safc with the stock computer may have to do for a while. All the big name stand alones are upwards of 2k..

[WAT TURBO?]

I am going to sell the turbo/manifold/wg setup thats on it. Should have a Precision 60/65 ball bearing turbo and a Turbosmart Racegate headed my way pretty soon.

I am also going to explore some megasquirt options. Anyone super knowledgeable on MS, I have a few technical questions. The standalone stuff for these cars are super expensive.

Mega Squirt is the way to go! looks like a fun project.

nice mr2 man im picking up one monday

[.:Stirfry:.]

is this the one the folks from NJ HI-boost 1.9 made a big callout to??

[Boosting EG]

nice car

[Franco Tirador]

u got too many toys................


let me have one lol

[NJSC]

What sort of numbers are you going to be shooting for?

[Sunkenkarma]

Sweet Mr2! Has awesome potential! More pics of the FC in the background >.> lol.

I bet it would make you sick if you knew how much I have in this car

[WAT TURBO?]

What sort of numbers are you going to be shooting for?

shooting for 450whp range. The 91 cars didnt come with a lsd :/ Its main purpose will be daily/autox with the occasional hwy wig splitting

[WAT TURBO?]

nice mr2 man im picking up one monday

Post some pics when you get it! Is it a 93+?

[WAT TURBO?]

Pics of the FC as requested.




Something isnt right here.....






Its always happy to see me

[WAT TURBO?]

Sweet Mr2! Has awesome potential! More pics of the FC in the background >.> lol.

how about a dyno video?

[Sunkenkarma]

Turbo LS1! What?!?! lol, Why are you building an mr2 with that thing around? xD. Looks very badass.

[BLACK_EK9]

Wow the FC is sick and the MR2 is badass too

[msanch24]

i love these mr2's. hard.

and that fc is just nasty. pretty darn cool

[Arm&hammer]

dam i am so jealous of both your rides i am loving the mr2 reps for you bro

[brownhornet]

Good choice on both cars. +1

[1CleanEg]

sick cars man!

[Bowenaero]

That FC is sick.
And nice find on the MR2! Just need a '93 lip now lol.

Like this (Berk Technology):



Those FN01R-Cs are the boss too. That's the route I'm planning on going with mine.

Here's another '93 lip; one of my favorite MR2 pics (guy's name is Michel on MR2OC):



And yes that's the Nordshleife.


The bigger light grey connector goes to the I/C fan (sidemount), darker one goes to the O2 sensor, and the small light grey one goes to the A/C compressor. Don't know if you have any of those though haha.

I've heard that during the first few years of production, the red MR2s had no clearcoat from the factory.

The 6-puck clutch is almost definitely an ACT if the PO didn't tell you. Very popular choice, and rightly so.

You're right about the 880cc injectors being too much for an S-AFC with stock ECU. To be making enough power to need 880s, a tubular manifold, and a TMIC, he would have needed to go standalone a long time ago. Don't know how the PO got away with that. I'm sure you can get a lot more power and tq from that setup with a standalone. And chances are you can find a good used AEM EMS or Hydra Nemesis on MR2OC for cheap. Very active for-sale forum on there.

The trunk scoop is not that effective at anything other than keeping rain out, so you're probably getting less airflow than with the stock sidemount. Probably still better though because of the core's increased surface area. If it's not your DD, you may want to take that off. Air flows over the MR2's roof and kinda tumbles over onto the wing, instead of sliding cleanly over the trunk lid. So not much flow into that small scoop. Looks cool though! lol

You're right about 91s not coming with LSD. But 93+ did. You can find a 93+ transaxle with LSD on MR2OC or RPMGarage.com for not a ton (relatively) or you can still buy a new one for ~$2100. Aftermarket LSDs are available too. Clutch-types seem to be the most popular choice (the stock one is a viscous coupling).

I can probably ID the coilovers for you if you can post up a pic. There are only like a dozen made for the SW20.

Be glad you already have the poly bushings installed! They're great, but they're very time-consuming and sometimes difficult to install.

Welcome to the addiction! Make sure you join MR2OC. Definitely an indespensable resource for the MR2 owner. Check out the Southeast regional forum; we have meets and/or mountain runs every couple of months. My name's Bowenaero over there too, so hit me up!

Noob with his first post on IA being very informative. Don't see many of these around. Other nooblets should take note.

[DVSRX-7]

Love the FC

[Bowenaero]

Haha, didn't realize that was my first post. I've done my time on other forums lol...

[civic gsr]

damn that rx7 means business nice toys

[revenge]

Thanks for the info! Ill join up there too. Im on mr2.com but its not very active. I LOVE the car and havnt even driven it yet! Thats interesting on the red 91s clear coat. Mine has been repainted a while back and thats probably why.

The coilovers are JICs i think? They are adjustable on the bottom of the shock.

I was about to order some megasquirt stuff simply because I couldnt find any standalone stuff for a decent price.

Thanks again for the info!

heres the dyno video of the fc

[Theycall_Metue]

holy shit! i would be scare as fuck driving that fc! and its the truth

[WAT TURBO?]

holy shit! i would be scare as fuck driving that fc! and its the truth

Its VERY scary on the street even on radials. Its insta boost!

[alpine_aw11]

I want another mr2, nice build. That motor could make some beastly numbers, 450 should be safe. People forget about how powerful the 3s can be.

[WAT TURBO?]

yea im hoping to run at 450whp ish and maybe turn up the boost for some dyno pulls. Ive got a 60/65 ball bearing precision on the way. Should make good power

[importracer]

Post some pics when you get it! Is it a 93+?

just a 91 turbo all stock with a intercooler upgrade

ill post up some im going to be looking for a turbo upgrade if you have some good pointers there greatly accepted.

and if you know of problems with tuning if i just upgrade turbo and nothing else yet?

I have an entire turbo kit with your name on it! its a 67mm with obx tubular stainless manifold and wastegate. Ill let it go waay cheap. Its been on my car for 4 quick starts. Never driven with it.

for something like that, from what ive read, you can use an safc or a apexi power fc for tuning purposes. Also the 93+ computers are more tunable than the 91s.

post some pics of the aw11!

[importracer]

pm me a price. and i know a guy that has a totaled 94 but its na can it still be used?
and what about suspension ive been looking but its very limited to choices

[alpine_aw11]

post some pics of the aw11!

That's long gone unfortunately, I don't even have pics of her anymore. That was a fun little shit to drive for sure.

[importracer]

lol on a side joke my buddie said his h22 hatch was going to out run the mr2 stock h22a his car will not even burn out
