Turbo Rolla

[phillfone]

I have been reading up on converting an ee90 2e to a 4efte. I have bought a wreked starlet with good motor but auto box, I am going to bolt the 4e-fte up to the old box cos I drive like a nana and the old one will hopefully hold up for a bit. Is using the ep82 starlet auto a mission to put in. I don't really l like auto's that much, but this one is in good nick

I would appreciate any advice or comments from anyone that may have done this conversion and any information on tuning or tweaking the 4e-fte. I ain't spending a bunch so doing most of it myself and only doing the cheap tweaks such as exhuast, coolbox, vairiable boost blah blah.

cheers

P.s Sorry for doulble post.

PPS ecu pin out diagram would be wicked if anyone can help

PPPS why does it say I am a gimmick poster under my name? Cheers

Gimmick poster is an auto thing it adds ... just shows everyone roughly how long you've been a member and how often you post.

Make sure you do a good search of the forum for what you're asking ... you'll probably find that in the few years TS has been running, someone has asked the same question

Good luck (sounds like a good idea for a conversion btw)

Cheers for reply, yeah there has been a few done, mine will be worked but drivable as every day car, my plan is totally stock granpa on the outside as much as possible, I not like the attention that the bling bling brings, mine will be bling on the inside. Goes to mechanic tomorrow will be finished in two weeks I post let people know how it goes.

Hi,

Thought ppl may be interested on an update on the 4e-fte conversion in my 1990 ee90 2e nz new rolla wagon.

Going into shop on monday for the 4e-fte conversion, I have a donor ep82 starlet with low k 4e-fte.

My idea is to keep the wagon looking as stock standard as possible on the out side, to the casual observer. Ride height will be stock, I am changing over to the 14inch rims with brand new but stock size tyres, that are on the wreck (will these fit?). It already has gti rolla front struts with std height king springs in the front (anyone got some rear std height king springs 4sale?)

The engine is been planted in professionally and wired in, to begin with the engine will be totally stock except for front mounted but hidden air to air intercooler from a twin turbo legacy, and custom mandrill bent exaust to give low noise but low backpressure. with cool box type intake and pod filter. I'm keeping rolla tank and upgrading lines, and fuel pump.

As much unessary crap is being removed from the 4e-fte engine as possible, that is what I love about lower spec std nz new corollas, no power steering, no air conditioning, no electric windows(how can people be so lazy?), no abs.

It will have vairiable boost from inside car and std interior except some small gauges, and no blow off valve.

New std man corolla clutch, new CV's

Is there a bolt on brake upgrade from another toyota with larger vented rotors and larger calipers?

Once this basically stock setup is in the car and running correctly I will let you know how its going, later on I plan to further upgrade suspension and breaking, and upgrade turbo, plus put as wide as possible rubber on some stock as possible looking fourteen inch wheels (any ideas?).

All of this is not costing heaps, and it will eat alot of later model bling bling show ponies (see www.beaterz.com), but with luck still be reliable and practical.

Bye for now.

PS Does anyone want ep82 starlet parts? including auto box, the rear of the car is not damaged, and most of interior is good. Front back to about radiator is stuffed, and bonnet screwed except for intake scoupe. make an offer, I tell you if I have it. Cheers

I would be inclined to use a blow off valve as it will help to stop compressor surge which is not healthy for the turbo and not good for response. There are a few plumb back bov's on the market at the moment which will work quite well.

Just get some plain looking 15" alloys off a trueno or levin, put some nice sticky tyres like direzza dz101's on them and you will have a nice grippy wagon.

You may be able to use the brakes off a ae92 fxgt or gtz, the chassis' are very similar to the ee90.

Should be a matter of swapping the hubs, calipers and disks I think, not sure if the axles from the 2e will fit as I have no idea what gearbox is on one of those.

yer aye

I thought about doing a 4EFTE conversion on my EE90 sedan.. but at the moment it;s really not viable.. itd be great to see how your one goes, maybe you can swin my opinion back in the other direction.

Cheers for the advice. I will look into the plumb back BOV and see if it fits the budget.

I will let you know how things go, at this stage the most complicated part seems to be the wiring, I have found all the wiring diagrams, and pin outs, and diagnostic codes. I have given this to my mechanic to speed up his progress. I will let you know if we discover any hicups along the way.

[phillfone]

ok engines sitting in bolted straight up to old box, everything has been a walk in the park so far, will post a pic shortly, I going to see mechanic today and see if he's started the wiring yet.

Ummm ok...All of the following is assuming the ee90 is the same as the ee80 suspension wise etc, which im pretty sure it is.

Front brakes - Try using the front brakes off the gt starlet, should be able to swap the complete front hubs. You can try the rea ones too, but might not quite fit properly.

suspension - should be able to swap over all gt starlet stuff, Id imagine it would be a bit better than the rolla stuff

Take it easy on the gearbox cos its not quite as strong as the starlet one, but should last a fair bit of time. Clutch should last a while, but I wouldhave gone with at least a gt starlet standard clutch - just seems more suited to the application, might be wrong though.

Wheels - I think you might change your mind about the standard rims the first time you take your car out in the wet, wheelspin city!! try going for some slightly wider rims, even something like standard 14" mazda familia rims look standard, but you should be able to fit 195's (should )

Was the corolla fuel injected? if it was there shouldnt be a need to upgrade the lines, they should be more than sufficient.

**** Please note all of the above is based off an ee80, so if theres a massive difference between the ee80 and 90 please ignore everything I said hehehe or if you think Im talking out my ass, please correct me im only human

Let me know if you need any more info, I did a fair bit of research for the same conversion on an ee80, but went with an ep70 starlet instead (only weighs 750kgs )

[phillfone]

Cheers Dude, no it wasn't injected so new lines and a vn? vl? comodore fuel pump was going to be used, I don't think the starlet tank will bolt in. It already has upgraded susppension in the front, but the brakes need to be upgraded. I can't take the front disc's off the starlet as one is smashed to piecies. I don't think the rear discs fit, but do you think the rear suspension will? it's an ee90 wagon. I will stop by and take a pic of the engine bay to post on here for those that might be curious.

Anyone got experience on tuning or moding the 4efte without blowing the budget.

Cheers

Ummm you dont need to mod the fuel lines even if it was carby...all you need is a bigger external fuel pump (commodore one will do fine) and a surge tank (prolly need a low flow pump between surge tank and fuel tank) ...the carby rolla only has 2 fuel lines instead of three, but you can use the 6mm (i think) one for a feed, and the smaller 4-5mm one for a return. Your mech should know this stuff

If you want to know anything bout 4e's go to starletcentral.co.nz those guys know their shit

You WILL need to upgrade the stock fuel lines, I found them on the limit with a 4AGE, so on a turbo engine you are asking for trouble.

And its a high volume low pressure pump you want between the tank and surge, and then a high pressure between the surge and engine.

I stand corrected

Based it off the fact that I was planning on running my stock starlet carby lines (same as rolla) with a surge tank and 2 pumps, and was told it had been done before with no problem at all on a 4efte running about 8-9psi.

Then again I might be wrong and corolla lines might be completely different, would be stupid cos theyre both 2e engines.

hehe, knew it was some sort of low volume or low pressure pump close enough

[phillfone]

Hi the rolla is still in limbo at the moment, as my mechanic is taking to long, I have taken the car back and at this stage the engine is in the car, now I am finishing the rest myself. I would like to here from anyone who has wired one of these puppies in as this appears to be the most daunting task at the moment any advise would be very heplful.

Cheers
