Project MRX350

Post by PW@Woodsport »

Well mental V8 Mr2's are one thing, although terrific fun and an excercise in boundary pushing, they don't make particularly useable everday Mr2s! I love the V8 to bits, just for its pure insanity factor and i'll never give up on it or sell it, but i also need a useable and fairly sensible Mk1 in my life.

Last year i bought a mint condition and totally stock Mk1b Tbar, drove it around the UK all summer and had a blast, rediscovered my love for the Mk1 in all its glory. The problem being for me though is that we build such extreme Mr2s day to day, and obviously get to drive them, that getting back into my stock Mk1 left me feeling a bit meh... i can't help myself, as much as i love standard Mk1s for me my cars have to have an edge about them, tuned the way i like them, with loads of effortless torque, an engine note to die for and subtle bodystyling very much in the JDM theme. For me such a car is perfection.

I know some will not agree with using such a mint example as the basis for a project but i've done the rusty resto route many times and it's a major drag, this time around i wanted a solid base, no welding to do, just concentrate on the good stuff.

So here is the car before work, everything on it is brand new, yes brand new from front to rear, every part bought from Toyota right down to the brake pad clips.



Image



Mad for using such a good car to start cutting up? Or sensible? Time will tell.



At this point the car had nothing more than a set of JDM rear lights and a SC lid with some Lenso D1R wheels, but i wanted to go more extreme on the styling, not a full kit as such, i love the Mk1 OEM look, so the idea is just to give it some steroids to keep within the original styling look.

This is achieved by fattening the arches, done using our universal arch molds, grafted into the bodywork and blended, so that they look part of the original car rather than bonded or riveted on. Now to fill these arches i'm going with my alltime favourite period wheels, Borbet A's, these wheels have a serious dish but not a lot of offset, so it's not like they hang outside of the cars original bodywork by miles, in fact the fronts only need a 3/4" extension to the arch.

Work started by cutting off my original arch lip and slicing the slope, then bending the tabs to suit the new arch and bonding that on, a lot of time taken to get the arch profile just right. All of this work is merely in the fabrication stage, the final blending and finishing work comes later. As with all bodywork projects they look rough in the pre sanded stage, the trick at this point is just to get the basic shape right.



Image



Years ago i built a similar themed Mk1 (which i believe Mr Brett now owns) with flared rear arches, the trick is to modify the sideskirts so they wrap around the wider arch, giving the impression that it all came from the factory that way....



Image



On the front arch this theme is continued making the sideskirt wrap around the wider arch, here it is in its rough fabrication stage with temporary screws etc...



Image



This will get the rubber trim replaced when it's finished to complete the look.



Image



On the rear, the same work is done to the arch...



Image



Image



The yellow lines are where i will be fibreglassing and profiling the arch to meet the bodywork, Mk1's have a steeper angle on the rear arch than the front, if i make the angle the same all round the car it won't look right, so the same angle as factory will be kept, it's small attention to detail like that that pulls off the final look.

Again the sideskirt is modified to wrap around the new arch...



Image



On the front of the car i'm using a Buddy club replica, we make these in two piece form like the OEM Mk1b lip is, it is just a fatter and more aggressively styled version of the stock Mk1 lip.



Image



On the car it fits around the standard wings, but because i have widened my arches it now needs to flow into the new arch, this has been done by flaring the lip where it meets the arch, again just rough fabrication stage....



Image



Image



This gives the front a stock looking but "pumped" styling.



Image



That is pretty much the styling taken care of, from now on it's just hours of sanding and profiling before painting, but the look i'm after is there.

The engine i have planned for this car is pretty much the reason for the project name, MRX300 is taken from MR2 and RX300, i'm using the 3.0ltr VVti all alloy V6 from the Lexus Rx300, i drive one of these as a daily driver and the engines are sublime. We just finished installing one of these into a customers Mk3 roadster, and it was an awesome weapon...



Image



Without hesitation i wanted the same unit in my Mk1, not much weight increase, silly amounts of torque but refined at the same time, so for the past few weeks i've been building this...



Image



225bhp and 224lbs.ft of torque, all of which comes on tap by 2500rpm and pulls right to the redline with a hefty kick up the backside when the VVti comes in, glorious.

Mated to this is a Mk2 Mr2 gearbox with a Mk3 Mr2 Torsen LSD unit fitted to it and Avensis Diesel 5th gear set taking the gearing from 0.82:1 to 0.73:1 for motorway cruising and i suppose a better top speed (if that's your bag)

Driveshafts are a combo of Mk2 NA and a Celica supported shaft arrangement, more on that later.

Suspension wise i'm ditching my brand new Toyota shocks/Apex springs and i've gone for these....



Image

£1200 worth of quality suspension capable of ride height, bump and rebound adjustment.

To top these off i've gone for Technotoy tunings camber adjustable top mounts...



Image



I need to look at some brake upgrades too, possibly some St185 twinpots or radial mount Brembos.

Interior wise i've gone for Recaro fishnets from a Fiat Strada Abarth, they look amazing.



Image



The plan is to also add my power steering system that i also have on the V8 Mk1, it just works so well.

So that is the project up to now, further updates as they happen.

You just can't help yourself can you? :lol:

Should be another interesting project to watch.

Not sure I *approve* cutting up a perfectly good Mk1 when there are plenty of donors out there. Having said that, I know from experience the difference between working on a sound mk1, which needs no remedial work and having to spend a shed load of time and cash on making a car good before the project gets underway.

Good luck with this one Paul. :thumleft:

It's a disease with no known cure mate. I had to weigh up restoring a rotten one vs using a solid shell and with my time constraints i had to use this one.

I need to try and finish it for Lemans.

Even though I don’t approve, I know which car I would chose to undertake a project on.

/hypocrite mode :whistle:

I'm missing the MK1s I've owned over the years at the moment. I'm after a track car and even though I said never again, I am seriously tempted for a 1.5 again.

Yep there is something special about the 1.5 swap, it will always be dear to my heart after building the first one in Europe, i loved that car and it used to demolish SC's, but the V6 bug is something else, maybe not the same outright power (non VVti version anyway), certainly not as tunable, but the rest of the experience is bliss.

The trick is converting a chassis you know will last though. :thumleft:

I think the engine conversion will be lovely. :+:

It does seem a shame to carve up what is a clean looking MK1. I don't think I approve either. Your car upto you and all that.

Not a fan of those wheels at all or the arches. It looks very similar to the V8 one you did. No offence intended, but I far preferred the car with the wheels it had on it before the grinder came out.

You've bloody ruined it! :tongue:

Agreed it's each to their own, i thought deep dish period wheels were your thing Lauren? Weren't you lookng for a set for the 86?

For me wide arches and deep dish wheels is a fantastic look when done right, most of the cars in your JDM thread have that very look.

What's not to like! :D

Judge it again on the finished article, i bet you change your mind :D

Have to disagree with most of Lauren's points I'm afraid :whistle:

I reckon it's the perfect base for it, you're realising your vision of your perfect MR2, I'm pretty sure that doesn't include 20-odd years of rot and plop, so starting with the best one possible is just smart. I suspect you've certainly done enough over the years to contribute to mk1 survival rates, you've more than earned the privilege to chop about a nice one :lol:
And yes, why spend loads of time fixing a rotbox up to the point where you can start doing the things you want if you have the keys to a solid one sitting in your pocket? Sound logic.

The Lexus v6 will be sublime I've no doubt, and having seen Ollie's mk1.5 in the metal I'm sold on the Borbet/arch combo too.

Eventual (we're talking at least 2years away here :( ) dream plan for mine is a more budget version of this, with BC coilovers, 3vz transplant and woodsport wide rear arches to make the most of my 8.5J rear wheels (currently rocking scene levels of stretch to hide within the stock arch line...), so I'll follow this with interest on here... and TB... and the mk1 club... :D

Green with envy :mrgreen:

Fair play, Paul. :+:

I do like dished wheels. Maybe it's just the Borbet's. I think to achieve that JDM look you need JDM look wheels IYSWIM.

I would look at a TE37V, Work Equip, Watanabe and all that type wheels.

I look forward to the finished article. You will be pleased to know I had much fun driving Steve's MK1.5 at Angers last Saturday! Felt chuffing quick!

You could be right there, i just have a really weak spot for the Borbs, but please no text speak on the forum :oldtongue:

LOL!

I don't want to hijack your thread, but I reckon Steve must have been peeing himself laughing, because when I pulled out of the pitlane and booted it, I was like 'fooking hell', then I changed gear and planted it again and it was a 'fook me'! It sort of went on like that until it started overheating after two laps, just when I was getting into my stride!

LOL, the dark side, indeed. Watch this space. :tongue:

Yep, insanely quick cars those 1.5s, i filled my huggies first time i drove one in 2000, all the power of a Mk2 turbo but 300kgs lighter, mental fun.

They've become less popular in the last 5-6 years for some unknown reason, which is surprising given how cheap Mk2 turbo donors have become, maybe people are a little less keen on cutting up Mk1s than i am :D

I think it's probably just getting harder to find MK1's that aren't rotten as rust really is a major factor now. I have to keep reminding myself that when I had my first MK1 it was only 13 years old. Like my current car the oldest ones are getting on for 27 years old!

Great fun though, I agree. :)

Cracking project underway once again from the mad man at woodsport! :mrgreen:

I think the MK1 looks like it's been on the Steroids :lol: Improved for the better in my opinion, with a beefy V6 to match the looks.

Looks good mate, keep it up :thumleft:

Not at all mate, I enjoy the difference in responses over the boards, from the more conservative mk1 club lot to the absolute nutters on TB, haha. Long may you chronicle your projects far and wide ;)

Love it, Love it.....LOVE IT!!!

I think I want another Mk1. I may need to find a garage to store and work on my cars, Its getting ridiculous!

I'll keep an eye on this thread with great interest.

Cheers, Michael.
