2GRFE Conversion - any inputs?

[beerhead]

I recently picked up a low K aurion motor for my next project, it'll be track only. I'm starting to get really handy with my tig, so the sky's the limits in terms of mods.

I'm really not sure whether to keep it NA or boost it. Maybe I RA60 improved production car might be smarter and easier, but I'm thinking something a little scarier.

Current ideas I'm tossing up between.
NA
KE70 Chassis
Porting, ITB's,extractors, tuned cross pipe
aim for 300whp
W58 / R154 depending...
Custom bellhousing.


BOOSTED
GT4 of some description - Possibly even a widebody camry with AWD swap
Late gen RAV4 box and rear diff cradle
forgies, sleeves, porting and GT42R
Aim 700whp

Planning to get the new E1280 Adaptronic to run the quad vvti with traction and launch control. Definitely the cheapest way to make a 2GR work properly.



Ah well I better finish my other cars first, AE93 20v 3S KE70, both of which are so close to rego now.

But I'm going to go mental on this one very soon. I have a bad case of 2GR fever

Anyone got any ideas I haven't thought of?

BTW I'm not an MR fan, so that's out of the question.

buy/build vw-powered sand rail, replace bug motor with 2GR, go off-road rallying and cut some hilariously large dirt rooster tails

I like it!

I've had thoughts of doing a RWD 2gr swap into a cressida or similar with a couple of turbo's hanging off it. A 1gr 2wd box from a hilux should make it a bit easier.

FWIW the Link G4 extreme and Vipec V88 both support the 2gr trigger patterns and quad vvti control, MWR are starting to do internals for them also.

+1 for boost. They came out with a charger so they should love a snail with a little work

Would make a great race; your GT6 vs Justens GT8

Keen to see what direction you go,

Kind Regards,

LOL 2GR dune buggy!
Beerhead was last seen jumping a dune in central QLD. Authorities believe that he possibly became airborne and broke the gravitation pull of the earth. If you see A UFO in the night sky check for a toyota badge in your telescope before calling SETI.

Back on topic!
Cheers for the interest! I've been leaning towards boost of late, would be a bit of an animal. Question is AWD or RWD. from most accounts the RAV4 center diff isn't active, they understeer like all crap, the factory 2GR rav's are known for under steer too.

Has anyone heard of anybody who's tried running with drive by wire and 4 wheel traction control on a GT4 or RAV to get it behaving under power in the corners?

I really loath the idea of cutting a 2GR block to run a 1GR bellhousing so for RWD I'll get a custom bell made that sits the starter like FWD but mounted down low.

A bellhousing will cost under $1000 to have made, Will work out cheaper than trying to score a 1GR for the bottom end, but I have been keeping my eyes out for them. Dam what a fail - I probably should have hit all the flooded wreckers!!!

Well the buggy idea has been done already see here

2GRFE already makes 268hp on standard 91 unleaded so getting 300hp should be a piece of piss.

Realistically a good exhaust alone and a tune with adaptronic on ultimate 98 could get you there.

Hell the IS350 is just a DI version and that makes about 315hp.

Understeering Rav's/Klugers...thats because the AWD only kicks in once the front loses traction your never gonna get oversteer from a RAV without some serious effort.

I would be going for something like an SW20 and shove it in the back. Or even an AW11. It has been done. A GT4 might be cool but its gonna cost you a lot.

Buy this and work out some way to replace the 1MZ with the 2GR... http://www.toymods.org.au/forums/showthread.php?t=64386


Guys from the US/UK have bolted these up to E153 transmissions pretty easily so a GT4 based transmission should be similar and you only need to worry about the AWD/2WD differences with regards to transfer cases, orientation and possibly sumps with subframes or whatever it the ST165 runs.

Have a look through this thread for a bit of info about putting one into a MR2 (I know its not your thing but the gearbox info could help, esp since wagonist was asking about AWD applications) and another going into an AE86.

[old_school_jap1]

No need to get a custom bell. A VZN130/VZN172 bellhousing will suit it for RWD and as Paul has said it should bolt up to the Camry/MR2 box (AFAIK all the V6s have the same bellhousing bolt pattern, it is just the 1GR that is different)

[beerhead]

Yeah I've bolted a 2S bellhousing up, but the way it looks I was under the impression the gearbox shifter would point towards the passenger at 15 degree's, which, wouldn't feel that good. Then the bellhousing still needs a rear entry starter modded onto it, I wouldn't feel right grinding the block for the starter.

I wish I liked the feel of MR cars, it's the easiest option, but I don't think its for me...

I'm starting to lean again towards a ITB KE70 + W58 to start with, then low boost it with a thick gasket if I want more power. The way they put down the torque it probably won't need boost. Light enough engine to still handle in a small chassis too.

[eeeyan]

dude a 300HP all motor V6 E70 Corolla sounds mental just writing it.

Should be more than enough for some sik skidz and these motors are pretty farkin tough and can take a hammering all day.

ITB could be tricky but seriously as the motor is as i said already near enough to 270hp then with adaptronic, exhaust and some decent fuel i doubt you would need ITB in a chassis that light.

[slipway]

itb gre70 is si where this engine needs to be, will be so awsome track car = open pipes too.

[old_school_jap1]

Mate the bellhousings I'm talking about are off V6s in 4WDs, they are to suit R boxes and have an angle built in to them to cancel the 15degree tilt that happens with S/Y bellhousings. Should be able to sort the starter on the right side too.....maybe a little bit of grinding.

[beerhead]

Needs a custom intake, so ITBS will be it! The noise will be epic.

Hmm, sounds like it might be the go on the bellhousing then, just need to tig a starter holder to the back end of it by the sounds, time for some wreckers hunting

+1 for this idea...although a boosted 1MZ would still haul. 165 chassis is a heap lighter, but takes all the tougher running gear,, so is the pick of the GTFours to play with as a track car. Not the cheapest option but up there for originality.

I'd be happy to loose to an AWD beast like that

[beerhead]

It's a hard one hey, I've always had a sweet spot for the GT4's, but I'm worried about how far the costs will blow out.

With stock CR, your limited to aaround 400hp, but that's on American fuel, so maybe a bit more on race fuel. I'm sure methanol or E85 would do the trick too ...I do have spares, so I can see what happens if I boosted the stock motor...

Thing is I'm a KE70 lover, I just wonder if you could get the same performance NA, in the lighter chassis, as a turbo AWD car thats got 400kg of extra weight. . Always loved the David and Goliath battle in motorsport hey, and leaving the motor in close to stock form will be much more reliable.
