I know this has 0 to do with magnas but im sure a few people have done it around here so

basically i have a 7m-ge engine in my car currently

3L inline 6, 24 valve DOHC bla bla

I am converting it to a 7m-gte

3L inline 6, 24 Valve DOHC Turbo

So as you can see its the exact same engine but with a factory turbo.

If anyone knows if i will require a brake upgrade? I plan on doing it some time in the future but if i can get away without it now thatd be sweet as

Also, does anyone know a good engineers in vic


Cheers

Last time i checked the brakes had nothing to do with engine size or power. But it is ALWAYS a good idea to upgrade your brakes if you are modifying an engine, especially if it is being replaced by forced induction.

Trav, did the factory model with the T have different brakes? Find that out, otherwise you wouldnt need to change. I figure Toyota wouldnt have sold the T without bigger brakes if it needed them.

Yeah good idea, find some specs on the cars that came with the option of that setup and compare brakes between your car and the other car.
Stick a 2J in it:P

nah they never made a turbo cressida, the twin turbo chaser on the same chasis but different engine (1jz) had the same front brakes bu vented rears which makes SFA difference! I will be upgrading from single pot front to 4 pot fronts just need to find all the bits :(

2J would be nice, pity its an 8k conversion!

How much is the upgrade to the factory turbo gonna cost? Are you just adding the turbo or just dropping a new engine with the turbo on it already?

from memory of research on the swap on the supra. the mk3 had the same brakes between the 7m-ge, 7m-gte and 1jz-gte. on that basis i would say not needed, but best to talk to engineer thats gonna sign off and give them that info and see what they say.

im gonna call the engineer tmoz, see what he has to say about it.

i was gonna just bolt the turbo on but im thinking i might put the entire engine in and do it properly

buy a ma70 front cut. with the 7m's head gasket issues ur asking for pain building an NA-T. with the front cut u get the right computers and gearbox as well.

+1 on this, cressidas are know for the headgaskets, chuking a turbo on a na motor is just beggin for more trouble unless done 100% right, which will probably cost as much as getting the front cut...

mate had one of the old square supra turbos, and he had no end of head gasket issues. Shame, cos it went like stink and look the sex too!

At a minimum, get some slotted rotors and decent pads.

im fully aware of the HG issue but it does have a simple fix,

clean the block up, get the head decked, use a MLS HG and some ARP Head bolts tighten to the revised toyota specs and bobs your uncle :)

anyway im gonna call the engineer now :)

Buy a damn 1J/2J :rant:

haha 1J costs about 4k before i have even looked into fitting it

my 7mgte is costing me $350 for the engine :)

Call Toyospares in Bayswater Vic, they do complianced installs of all sorts of motors, do kits to install them and know what will pass and what you are simply never going to get away with. Will save a lot of heartache later

Heres a few snaps i just took of my step brothers work in progress, thats his spare parts car, on its side to get the diff out easier. Dunno why he wants the diff, i remember him saying its the same one the supras came with( correct me if im wrong) whole car is completely gutted of everything he wants except for the diff. Engine is still in it, he got it for free because of a blown head gasket... Thank god, its only taken him over a year to do it, cant wait to see the eyesore leave the front yard....

He is saving funds to drop a 2J in his MX73, think he is getting a personal loan to do it, i cant see the sense in it, just buy a supra or something would be easier.

unfortunately toyospares are the worlds biggest ripoff merchants, they know their stuff but they do charge for it (they wanted $2500 for a 7mgte :doubt: ) i might give them a call butmy engineeer seemedf pretty happy with what i have

the main issues with an NA-T, even with the HG fixed, are higher compression in the NA motors which can cause detonation issues, different cam profiles, wiring and computers, differences in gb and diffs.

what were u planning on doing for ecu? staying auto? NA auto prob wont like the extra power/torque and the torque convertor/ shift map of the NA TCU def wont want to play properly.

you seem to have done your research quite well. have you looked at wiring differences between the NA and T? i mention this because while just buying the turbo engine may sound like a cheap swap. if there is big wiring issues the extra outlay for the front cut and having the complete loom may end up saving money.

what 4pots you plan on using?

the 7m-gte is a great engine when treated with a bit of love, but make sure u get it right first time. it'll be a sweet ride when done. anything i can help with (still got a few 7m-gte parts laying round) just give us a shout.


Tim

Cheers for all that tim

i was planning on going na + t but now im going to straight turbo conversion

i have a turbo auto im planning on putting in from my mates supra, but in about 2-3 months i wanna go manual (what fun is a auto turbo hehe)


Wiring isnt an issue i have the two wiring diagrams + a few mates to help me out with beer payments :P

umm the 4 pots are from a r33 gts-t + BA falcon disks and a smaller hub locator ring (which has been ADR approved, alot of the 1J guys run this)

Tim, if you have the turbo oil lines thatd b wicked but i doubt you will have them :(


as for prep im changing every possible gasket and seal while its out including the rear main seal etc. Im using a cometic MHG and APR head bolts so that should sort the engine out. Im also doing the piston rings, vavle stem seals and valve springs while the engines out too., lotsa cleaning of bits and pieces. A mate of mine works at martini racing so i will only the best lube in the car ;)

Trav

brother seems to think we do have them, will have to search the shed on days off and see what i can find.

cheers tim, im really only after them to get some braided ones made up so i can send them back to you if need be :)

Just hop over to Toymods and ask over there.

www.toymods.net I think

yeah mate im on toymods and every one of the million toyota forums :)

cheers for the heads up though

As you may or my not know i am doing a Conversion on my Festiva....

BP DOHC 1.8 (KF TX3) into a WA Festiva and i am not required to up the brakes but was advised......it is better to be safe than sorry.......

Cheers Craig....

thats a much bigger change than i will be doing! haha
