Hi guys been awhile since been on hope everyone OK. Just wondering were people have had there v6's done and who has done this there selves as seriously thinking of going this route thanks in advance for your expert advice as always
Rogue motorsport in Southam mate.
Also woodsport do v6 conversions
Woodsport all day f ing long.
Check out their web site or have a gander at twobrutal.
Rogue or woodsport as above s:) :) s:)
If it was me I'd visit both for a good chat and look around (both will make you feel welcome) I'd also try and track a member or 2 down that's had the same work done by both and get their views (off the open forums)
Keep us informed on how you get on dude s:D :D s:D
Cheers guys. Yea these were the 2 I was thinking of just wondered who has experience with either can't remember who used to have a v6 on here as ain't been on for ages and lost touch with it all lol
Which V6 to go for is also a good question.
pretty much has to be a 2gr if budget permits
2gr is very expensive but its what I'd go for budget permitting.
However not everybody wants 300bhp+ and there are other engines available.
1mz vvti is quite popular at the mo

I think we all do.
That yellow one in Scotland that recently sold was a great buy! I was very tempted by that myself. Do like a yellow car me.
I think thats in the Coventry area now
Tomos has it.
I very much enjoyed my ride.
All that low down torque.
The sound was awesome too.
2gr would be the engine of choice ( or the Audi V8 s:) :) s:) ) but sadly it to dear prob go 1mz. Just shame there no places in the south east that do it. Mate works in a local garage it Dartford that do cars up they got there own BMW track car so are tempted to go there as they know the car and I'll get mates rates lol. But this will be there first v6 in a mr-s were as the other guys have done loads desissions desissions
I would love the V8, but must be a pig to service.
The 2GR adds 60 kgs over standard. So ideally need height adjustable suspension. Coilovers.
A V6 conversion requires an access panel under the soft top to get to the other side of the V. Bit more noisy in the cabin and soft top may not always pack down flush.
More power needs heavier clutch. Takes away the standard ease of driving.
I think most will say the 2zz is the simplest conversion keeping stock feel.
Or turbo the 1zz.

Don't think anyone has done a mk3 V8. Certainly not in the Uk. There was one attempt on here wasn't there but it never got finished?
Wodsport did a mk1 V8 was for sale earlier this year on piston heads i think.
Come on Scott you can be the first completed roadster with a v8 in the UK!

I think a few of us should get together and look into it even if we only owned a hundredth each it would be awesome and we'd get 3.5 days a year each.
I have seen installs of the V8, MR_S and Roadster, even with the engine running, but have not seen any being driven running, I wonder if Woodsport have installed any? if we all owed a hundredth that might work.

You haven't won it then? That was the only reason we are always so nice to you Scott! (Hope you've got your ticket for tomorrow).
Can you have from 24th to 27th December?!
I think more people should get V6s and that way I may get a go in one too!
1st Dibs on a hundredth of a v8 mk3.
Is the lexus v8 a match for any fwd gearboxes? Thats a good pairing. It's light (i think its all ally, am i wrong?) strong as and takes to tuning and boosting with ease and it's cheaper than a cheap thing on sale. And it's a million billion gazillion times better built than any Ford or chevy 8 Fact!
Wait one second it was my idea i get first dibs.
£300 per share.
Audi V8 and box seems to be favourite by those in the know although some form of lexus V8 would be cool to keep it in the Toyota family.

Careful Simon there is always a chance i might.
Fair enough. Second dibs. It's actually not a bad idea. Any driver policies are way cheaper than you'd think too. All our work vehicles are any driver over 25.
Well it my idea for the v8 pluss my car so I get it at least 2 weeks out the year lol
If we're using your car then fair play.
Are you seriously considering the V6 conversion?
I had a ride in one and loved it but if you look at the performance/£ a turbo makes much more sense.
Saying that a 2gr may cost something like 10k but its a bomb proof 325bhp from woodsport.
Would a 1zz turbo prove as reliable?
I think its fairly safe to assume that modified cars generally will need keeping an eye on more than stock. Turbocharged Roadsters certainly aren't fit and forget, in my experience. I found the V6 took me a while to get set up how I wanted it, mainly due to being the first one, but once fettled, it was pretty reliable.
The V6 conversion, apart from the 2GR, is not about raw figures, as many turbos are more powerful ultimately and cost less for the bhp gain. Its about driveability and being able to enjoy it all the time, not just when giving it some beans.
That won't appeal to everyone, but its my favourite, if I'm honest. Noise is a big part of the package.
Aurally IMO the 1zz lacks character something that a V6 would put to rights.
If money no object i would have a V6.
Yea Deco interested in doing it would prefure v6 to turbo as more reliable I'd think and the noise would be awesome but sadly the 2gr will be out as just bought new gaff ;( Scott I'm only down road from Bromley in Dartford so once it done u can join me in a spin mate
Always up for a spin.
I don't want to say anything about reliability too tempt fate.
The joy of going V6 is that you can go FI afterwards if you want more power.
Think Tomos is going supercharger for his.
Awwwww super charged v6 that will sound the nuts. Haha good point don't want to jinx it
There's a trd supercharger on the bay. Perfect for the v6

Lead me not into temptation
Rich your a naughty boy
Maybe i'll just take a peek s:wink: :wink: s:wink:
This may now sadly have to go on hold due to house issues s:( :( s:(
Is that code for SWMBO said HOW MUCH?
Haha na mate ovens broke so while I got to replace it gonna do whole kitcken just temp set back plus she don't know be a nice surprise for her lol
What is the weight difference between a V6 and a turbo 1zz?
I've googled the weight difference between 1zz 1mz 2gr 3sgte.
3sgte is heavier than the V6s i think.
1zz standard is somwhere around 50 kg lighter than 1mz.
Turbos vary depending on setup.
Try a Google search.
Remember the gearbox gets swapped and you gain weight there too.
General engine weight info in lbs.

This is helpful for 1zz 2zz and 2gr info.

There's a great clip on u tube of 2zz turbo pretty much destroying all the yanks v8 in the states very wild and with a turbo set up its always possible to upgrade as the funds come in .
A v6 isn't for outright power its for the experience so to speak. Reliability would possibly be better too.
If you want a 4 cylinder swap go for the Honda engines.
Vtec is different league to vvtil imo.
My feeling is try and speak to people who have had work done at the places you are contemplating. I go on the logic that a company that builds racing cars will make a well sorted and robust install.
The 2GR swap is going to cost more than some other V6 conversions and you will need a stronger gearbox for it. If I where going for a 1MZ, I would try and pick up the vvti version.
Turbo will be possibly cheaper and definitely lighter (my turbo setup weighed less than the stock setup), but you get lag. The V6 noise is nice, mind, I like how my turbo 1zz setup sounded.
The other consideration is that once you start putting big boost into a 1zz, the gearbox needs money spending on it too and even with the Jubu gear set you are limited in the amount of torque you can transmit, so the bigger power numbers are going to cost whichever way you do it.
I've spoke to Woodsport and Rogue and both are extremely knowledgeable about the conversion. But price seems to be a factor between the two of them Woodsport coming in the better.
Although I've not needed a vast amount of information as yet Paul at Woodsport has been nothing but helpful when I have rung for information mostly regarding the breaking of the RX300 to gain my donor lump.
I'm no expert on this but as 1979scottie said the 3SGTE cast block is indeed heavier than the V6 1MZ-fe and you have 2 gearbox options the E153 which will handle lots of horses or the S54 which is lighter than the E153 and will handle the horses/torque I will expect from my build.
If you want me to forward it I have a price list breakdown email from Rogue which I could send you. PM me you address if you like.
I'm pretty much sure although further away for me I will be visiting Paul Woods for my conversion.
Give both companies a call and have a chat it's well worth it.
Quote from: "1979scotte"Vtec is different league to vvtil imo.
Only really applies to K20A, which is a beast when tuned to be fair.
For me, 2ZZ > B18C. I have
lots of ownership experience with both of these.

I can offer my experience with USPSPro's 2GR swap. I've put 60K miles on it since I bought it completed in 2010. I came up with 200lbs added weight with the 2GR engine and S54 transmission. It had a fierce clutch pedal when I got the car, but I have fixed that with an in-line pneumatic clutch booster. I also installed an access panel on the rear shelf. It lies completely flat. All the soft top parts are installed and work like factory. It is a little fiddly to remove the package shelf and carpet to access the plate, but I only need to get in there infrequently to reach spark plugs or coils. I'm not sure about suspension reuirements. 200lbs extra weight is no more than carrying one passenger, but of course a lowered and stiffer suspension does help handling the extra power (and speed!) Mine has three catalytic converters so the exhaust note is very deep and quiet. It sounds equal or even more quiet at low RPM than my stock 1zz spyder. It does growl pretty good at wide open throttle due to the K&N intake tube. For reliability comparison - I've never owned a turbo, but this V6 swap has 80,000 miles on it without any fiddling or repairs that I would blame on the swap. In 60k miles I have only replaced one coil, and two axles. The axles were cheapo aftermarket parts. I replace the both with Toyota factory pieces (cost about 8x more than the ones that wore out). Driveability is utterly fantastic. It will accelerate smoothly and very strongly from 600rpm to redline. I do passing in 5th gear at 3000rpm with plenty of acceleration. Of course shifting down and punching it up to 5000rpm will get you up to illegal speeds very quickly. I hope my first-hand experience helps.

Thanks for sharing. Would love some photos of your access hatch/panel, exhaust system, clutch booster. Have you got a project page yet?

If you feel that way superart then turbo is the way to go.
The TTE turbo kit was the only Toyota approved significant power enhancement for the roadster.
Just because Toyota didn't do it doesn't mean we shouldn't.
The car was produced to a price and to meet certain market demands.
A V6 would have changed it's market sector and price point.
Who knows what was marketing department decisions and what the engineers thought the car was capable of.

*Here* (http://www.mr2oc.com/showpost.php?p=3795537&postcount=1)is USPSPro's build thread from 2010.
*Here* (http://i1101.photobucket.com/albums/g430/paulshibbs/2GR%20swap%20pics/Installedcoverplate_zps54aca3d3.jpg) is a picture of the access door I cut. Only peeled the ragtop away for access cutting the hole. To use the access panel I just have to remove the package tray and fitted carpet piece. *Here* (http://i1101.photobucket.com/albums/g430/paulshibbs/Access%20Door%20for%202GR%20spark%20plugs/Accesscutout_zpsb9ddca7d.jpg) is the access - plugs and coils.
*Here* (http://i1101.photobucket.com/albums/g430/paulshibbs/Clutch%20Boosters/backside.jpg)is the pneumatic clutch booster. Neat little unit, just like a brake booster but no pushrod. It installs in the hydraulic line anywhere. I stuck it on the rear crossmember *here* (http://i1101.photobucket.com/albums/g430/paulshibbs/Clutch%20Boosters/Installedbooster.jpg)
*Here* (http://i1101.photobucket.com/albums/g430/paulshibbs/Exhaust%20tips/Removedmuffler_zpsf23127ca.jpg) are the only pictures I have of the exhaust system. Bumper-off picture shows the aft cat, and if you look closely you can see the notch in the rear crossmember to accommodate the aft manifold. The muffler *here* (http://i1101.photobucket.com/albums/g430/paulshibbs/Exhaust%20tips/Loadedmufflerfortheweldshop_zps19138609.jpg)is pretty standard single inlet - dual outlet mounted by one V-band clamp.

Toyota did do a V6 Roadster as a design study. Looked brilliant. No problem with the balance and feel of a V6 powered Roadster, its definitely the best incarnation I have experienced in 10 years of owning and driving them.
Would the best way of doing a V6 conversion be to buy a very cheap car with a knackered engine and then fit new brakes, suspension etc during the conversion?
Any other things that would need changing?
Seems to me it would be better than taking out and selling the engine from a lower mileage/working car (plus would help to keep more two's on the road).
My 2GR has original 1zz radiator and brakes, everything is stock except coil over suspension (and bigger wider wheels). I even have AC and factory cruise control. I'd expect a cheap car with blown engine to also have neglected shocks, tires, etc etc.
