Unfortunately, just after finishing my DOHC Gemini [few threads lower] i had the misfortune of having a decent accident in it. Bonnet flipped up into the roof at 100kmh and made a pretty bad mess of things. Have since sold that car to my dad who will be rebuilding it back to stock and all the DOHC gear will be going into my new aquisition....

Stock as a rock 1.6L Auto, im the third owner from new. The previous owners had it for 15yrs and in the past 5 its only covered 4000km.

Thanks dude. The aim with this one is to keep it looking standard on the outside but hopefully get it running in the mid 14 second bracket over the 1/4 all while naturally aspirated. Also hoping to do a few motorkhana/hill climbs in it, i think i might need a different wheel/tyre combo for that one though.

Ok, some old updates some new. Got the ECU remapped a while back, made 82kw atw, or 112hp at the wheels in the US measure. Not bad for a standard engine based in the 70's ay, considering the only mods were the ecu, exhaust and a bigger throttle body. Just to piss off the Toyota-philes its more then iv eseen from modified 2TG's and 18RG's....now where is the emoticon for the middle finger....

Unfortunately, unsure why but it lost oil pressure [maybe it was the fact that it was seeing the 7000rpm rev limiter every day?] and consequently spun a bearing. So, like deja vu, im at this point again...

Image

Insult to injury...

Image

MX5 seats

Image

Just a teaser on whats going in. Yes its a SOHC, no its not going to be standard....

Yeah, should tell that to my mate with the 4AGE KE70 who just ate his motor the same way as mine, despite not being treated as hard :lol:

Was originally planning on building a spare G200 ive got lieing around with a monster cam and quad throttles, but it was still going to be too slow for my liking, so....

161 EFI with a T28.

Thanks dude.

Some updates, should be an interesting/productive weekend if my cam and turbo arrive like their supposed to on friday.

First port of call, opinions. Hubcaps or wheels painted like this with the chrome dress rings?

Image

Image

New steering rack. Tie rod ends were shagged on the old one, steering column coupler was fucked. Would explain why the car never felt right going through corners.

Image

Heavy duty valve springs. Gotta love trade price - $60!

Image

HD Exedy

Image

Fucking filthy 5spd box

Image

Now the fun stuff...

Custom plenum on Rodeo 4ZE1 runners

Image

Image

Turbo manifold. Need to change the flange and block the external wastegate output...

Image

Rebuilt the head a few weeks ago...

Image

Image

This went in [Crow cams turbo grind #2]

Image

Viola

Image

Screwed the engine together and dropped it into the car along with the 5spd and inlet manifold.

Image

Should have the hot/turbo side done by the end of the week, will post pics then. I kinda, sorta, got carried away...

As for opinions on the wheels, I'm tempted to say hubcaps for that perfect sleeper look. I'd just be worried about losing them with the way it sounds like you'll be driving it.

Hubcaps fell off a few times with the DOHC in it. This time itll be alot faster, cant afford to risk mauling my quarter panel from a flying cap. So i think ill do it this way...

This is going in 2morrow :D

Its back - sort of.

Image

Made 215rwhp on a conservative dyno. How conservative? See below.

It killed a heavy duty clutch rated at 240rwhp in under 400km....

Apart from the mild-grind cam and HD valve springs, the engines a fresh-but-standard early model G161.

All the bolt on stuff is good tho - Garret T3/T4 roller with external gate, 3" dump with screamer into 2.5" exhaust, 4ZE1 runners with custom plenum, VN V8 hall effect and a Microtech LT10s.

Its pretty much at its limit atm. We left the timing as-is to keep it conservative and ran boost through it instead. The engine is simply not capable of spinning the turbo any harder/making any more boost. We took the hose off the wastegate and raised the rev limiter to 9k and nothing happened - stopped building power/boost after 7000rpm.

I could try a slightly bigger cam, bigger headwork etc and itll probably squeeze abit more power out of it but as it stands, its fucking quick. Turns second gear hard on the roll.
