Zimmo's 1991 2GRFE project

[GDII]

That looks nice. At least they took off the front bumper to paint it, my A/C radiator is red because they didn't mask it up or remove the bumper.
Black primer is a great idea on a dark coloured car for paint chips. I've never thought of that as it's usually red or grey.

I'd love to see this thing supercharged, as far as I know no one here has done that in an SW20. What power can the kit give these engines?

[Zimmo]

Ah thats not good, looked like a pain to put the bumper back on though.

Well from my research and what gouky has informed me the first thing to happen with forced induction is head lift as the headstuds are weak so they have been replaced with ARP ones. The second thing is larger injectors so I have long nose higher flow ones with Radium fuel rails and fuel pulse damper. Then with about 8psi you should see around 400-450hp atw much higher than that and you are looking at forged internals.... Seems the stock crank can handle much much more than that.

While 450hp isnt an amazing raw number I believe with the delivery throught the v6 it will be a handful.

I'm wondering if the stock gearing of the e153 will be ok with the v6 or if a longer final is needed.

Hey mate welcome aboard. Will be nice to see this wee beast of yours on a run sometime.

I'm going to move this thread into the Rides section where it can get the attention it deserves...

What do you want me to rename it to?

[Zimmo]

Maybe 1991 2GRFE project.. I'm bad at heading you can have creative licence

Like the look of the car. Very much in the same style as mine. I'm currently running no rear spoiler and like the look. I'm going to track my car so don't know what exactly I will put on?

The colour looks like Dark Emerald Green which is the same as mine but mine is a Gen 2 GTS T Top. Im also up for a repaint so thanks for the info on your respray.

Welcome aboard and hope to catch up soon. Cheers Ross

Welcome 2GR brother!

The stock e153 gearing is not good for V6s. Especially with the stock 6500rpm limiter.

There are final drive options (3.6, 3.9) from other gearboxes that fit , but they're quite rare - especially the 3.6

Thanks alot! Yes its Dark Emerald Green, according to the paint computer there are a few options of that colour from the factory over the years. I am really happy with how it looks. Are you going to do something like superlap or turn it into a full time track weapon? I often watch the MR2 Australia red 5SGTE race around the track on YouTube and looks like it does well.

Look forward to seeing your car in person.

Oh nice a AW11 with the v6! Must be a blast! My friends husband who live up north has a younger brother with one... really wanna see how they go!

I will be setting the redline to 7500 as I will not use the stock ECU... hmm I better start to be on the lookout for a final drive option though.

From a bit of searching on the web, I've read about and seen experiments done with the 2grfe and it really starts struggling above 7000 rpms. Setting the limit to 7500 rpms will probably show drop-offs in power as the VE decreases. If you use a Link G4 ecu, you can use the variable cam timing to help reverse this case and at least reduce the loss of power.

This is just the info I've read about, but there is nothing like first hand experience so I would say go for it and find out what it does.

Will be interesting to find out, I have no real idea as I haven't finished mine as yet however I believe from what I have read that the Lotus Evora revs out to 7,200 in sports mode, peak power coming on at 6100 rpm and torque at 4300 (on the dyno), so I didn't want my redline set just 400 after peak power.
I have fueling sorted, headers and exhaust with no factory cats to bottleneck anything, only other thing I can think of is larger throttle body, the VVTi will be expensive to tune across the rev range but yes I agree it can help reduce power loss. The wiring should (fingers crossed) be finished in 4 weeks then off to the tuners.

My Car is pretty modified with the following; dont know all the specs but heres most of it
T3/T4 turbo
Head rebuild and Athena Multilayer Racegasket
Heavy Duty pressureplate, 4 puk clutch - throwout bearing
Upgraded fuel system Walbro 255 and twin entry etc
Megasquirt ECU
JASMA freeflow exhaust
Upgraded Intercooler but still not enough

Just having water/methanol injection installed right now and should be on the dyno tomorrow. let you know how it goes. Cheers

That's better than my engine, my cam setup on my 3sgte means that I'm making peak power at the rev limit, and it's already raised to 7500rpms . http://mr2.org.nz/phpbb3/viewtopic.php? ... &start=251.

Very nice setup!! I have the AEM meth kit but I dont think it will help my NA v6 much. Very interested to hear your dyno results, who did your tuning?

So you have to live off the rev limiter! Sounds like many people here have very nice cars.

I'm heading to the workshop tomorrow so I'll try to take some photos of the inside and engine.
