Supra NA to Turbo

[Dan@DB-Power]

I thought I would start a little project on my newly acquired Supra:-

http://www.sxoc.com/vbb/attachment.php?attachmentid=71270&stc=1&d=1295823432

Spec at present:-

2JZ-GE engine
5 Speed W58 box
TT LSD
TT brakes front and rear (4 pot fronts, 2 pot rears)
Veilside Kit
Veilside Andrews Wheels


So far extremely impressed at how the Supra drives, feels and handles :nod: It's a big car but doesn't act like it :no:


Anyhow future:-

Thicker HG to drop the CR down to 9:1
Top mount T4-T61 turbo
FMIC
Injectors
AEM piggy back ECU
Exhaust

Anyhow 550bhp here we come :)

Enjoy!

Nice one dan :).

[KamS14A]

looks really nice, love the sound it makes, although do love the turbos ones bettter lol

[nevins]

So are you going for na-t or na-tt.
Cost effective and tuning potential would be na-tt.

[Madda]

Looks very clean Dan, good work :thumbs:

[nevins]

Also if going for 550, you would be best going na-tt and then going single as a bpu will be pushing it for that power.

[Dan@DB-Power]

I was going to go to NA-T as it's much easier to do and shouldn't be too laggy.

There are kits on the shelf for this too. haven't seen any TT manifolds yet as I believe the head flanges are different :(

Dan :thumbs:

[m.d.]

are the internals strong enough just to drop the compression and nail a turbo on,

i mean do they have decent pistons and rods in the NA etc??

lovely looking car there btw. always wanted one of those

[samcash88]

loving the look of this dan, always been a fan of mark 4 supras and by the sounds of it its definatly going in the right direction! You waiting for the warmer weather to start it?

[Tricky-Ricky]

I think your going to struggle with trying to run 500-550BHP on an N/AT, if you want decent power, start with a TT lump, they are stronger and so is the six speed box.

Although tough, the N/A internals are not as tough as the TT, with big power you are lacking the TT oil squirter's, not sure if you can retro fit.

Same rods and crank :) the only difference is the piston compression and piston squirters I don't see them causing any troubles :no:

nah will start it next month. Want it packing a punch for the road trip to Le-Man :)

Loads of 500+bhp N/A's about :)

The block is the same the only difference is oil squirters and piston compression. There are RB30's running over 1000bhp with no squirters so shouldn't be a problem :)

The gearbox is a concern, it will fail if pushed too far. so in the meantime looking for a R154 box off a 1JZ :)

Dan :thumbs:

Trip to Manchester and back turned out well then ? :)

Dan :thumbs:

Unless you're running a nice thick head gasket, or lower comp pistons, you wont get 500BHP from the std block, the most i have heard of is 420BHP, have you been looking on the US sites for power figures:wack:

[Dave270R]

Looks nice Dan :thumbs:

[pegliobagli]

Lovely car mate,sounded nice when you drove off too! Look forward to seeing this progress!

Dan :thumbs:

squrters will help a huge amount with longevity and general protection for the engine, its why ive fitted some to my '30. It isnt costly to do if you have the engine apart so if you can be bothered it would be a worthwhile mod

[dacky20]

i had the same very conversion done from 3.0 n/a to single turbo and i was ruining a huge t72 ill try and drag my thread over from the supra forum for you could be alot of help for you mate !
p.s i was running 512hp no problems bought the car for 2k and spent 2k and sold for 9.5k so not a bad little investment either ;)

[S3 1MDl]

you will surely need much much bigger brakes dan and thus should sell the 4 pots to me :D

[IKRAM]

Nice base to start with dan. Ive had my TT for a few months now and love it.

What tricky has said is correct, this subject is often talked about on mkiv.net. Also a good mate who I look after the welsh supras with has a very good set up for a na-t at the moment. Its a monster tbh, but to get where he is has been a nightmare. To get 500 in this kind of set up you will struggle.

The box is going to take hell of a hiding. To be fair it will be cheaper to TT bpu, it will be cheaper in the long run and more reliable.

[Dan@DB-Power]

I'm currently looking at TT engines and other engines ;)

Carried out a little mod today, de oranged the side repeaters :)

[alanjuggler]

isn't the engine bay big enough for a v10 ? :D

[zeppelin101]

You could upset everyone by slapping a dirty great V8 in it.

Nothing upsets other people like a V8 swap these days :wack:

[Dan@DB-Power]

Yes it is, just about. I have measured :wack:

nah, V8's are done to death but then again so are huge powered 2JZ's

[Daz]

If you want to annoy people, put a diesel in it :wack:

[Dave270R]

How about a 1JZ - cheaper than a 2JZ GTE...

[Ashleyyy]

Looks clean did you manage to decide on a wheel choice for it? :thumbs:

[Damo]

i think you should keep it n/a and stick ITB's on it would sound nuts

[m.d.]

I'm with dammo here. If it's a road car then it doesn't need 500 bhp to be fun.

Just get another 50 bhp from the na engine with cams ported head and an open throttle body set up from an M3. Loads of torque and the noise would be sex.

[59bhp]

what about a 3s? or 5s? top secret style

[nevins]

i think you should keep it n/a and stick ITB's on it would sound nuts

Been tried to death and it is an expensive route to go down for hardly any gain tbh. Iirc there were talks of using the m3 itb's for the job. We have a few members who have gone down the super charger route as well and brendans is proving to be a good set up

Yep! we have had plenty reckon they could achieve from 250 to 300BHP from the N/A Supra, but even 250 has yet to be seen:nod:
I'm sure 250 is possible, but you would need pretty deep pockets.

[Daz]

Dan,

Saw this at a jap meet last night, thought you'd like it.

[nevins]

Nice looking example of a uk spec

[JayS15]

nice looking clean car apart from the nasty veilside kit, in japan the kit has a rep for being fitted to rough cars because its a cheap kit to fix shoddy work. i wonder why veilside aint around any more?

[nevins]

Where can you see a failside kit to mate all I can see is a stock uk spec. Also failside is still around and not a cheap kit if genuine. They are also one of only a few to actually submit their kits to a wind tunnel.

[Si]

Ugh. LM reps. GTFO.

[Quail]

A Veilside lip and skirts is hardly going to hide a rough car.

Umm, they are? Making kits for Bentleys and Lambourghinis...

(Not as ugly as their original offerings, but still rather ugly).

[nevins]

Ugh. LM reps. GTFO.

Lol, Rota at it's best :D

[nevins]

Can someone please tell me where they can see failside parts

Blonde moment the original car lol

Just to point out aswell there are no veilside parts on that car skirts and spats are oem parts as in toyota

[nevins]

Its also a Bomex lip

[Tricky-Ricky]

Had me going too, there are no Veilside parts on any of the Supra pics:no:

Don't know where the cheap came from, lots of fake stuff about, but genuine Veilside is far from cheap.

100% agree mate. Its just done to death, main thing on the supras from japan are TS, Doluck, and failside.

meh sod the hp out put its all about the noise and having as much fun driving the car in stead of ripping it all apart to possibly end up with another car it bits

is there something VERY wrong with that wheel, or is it just an optical illusion?

[andy bird]

illusion due to the dish.

I have just purchased a Supra NA too and intend on doing this very thing NA-T

i intend to use the GE block and internals and swap the pistons as they are the same fitment.

then a bolt on and see what she will make (obviously with corresponding trnasmission and fuelling mods)

[59bhp]

is there something VERY wrong with that wheel, or is it just an optical illusion?

what, apart from the rota emblem?

[Quail]

I can count 20 things wrong with that wheel. The fact that it's Rota, isn't one of them.

[Tricky-Ricky]

So Rota is classed with failside now then? so whats so bad about Rota? i have heard about one failing but not loads?

[MEL]

I think it's the "split rim" thing aswell as being a blatant design rip off

[Quail]

I said I didn't care about them being Rota! I'm well over the whole fake wheel debate. AFAIK Rotas don't break any more than any other wheel.

It's the 20 glued on bolts which make the wheels ghey. I guess I'd be hurting more if I owned a real set of LMs, à la Si.

Doesn't matter what brand they are, fake split rims are just wrong...

Its an easy job to do really, as this is what craig has done with his n/a. No need to really change the pistons either as it will run fine with the n/a lumps. Blocks are near enough the same but the gte has oil squirters.

[adzn2k]

Lol back when i had a supra N/A and got a craving for more power everytime I searched all a found was "sell it and buy a TT" or "go the TT route instead" all I can say Dan is lovely looking supra i'm sure you'll do somthing special with it :D

how about an RB engine :D i'm sure i've seen a pic of an RB supra some where

[Daz]

Doesn't matter what brand they are, fake split rims are just wrong...

You say that but I thought they were BBS LM's until I noticed the Rota Logo. I had to compare them with another supra with real BBS LM's to spot the differences.

[cr33ch]

It might of already been answered but is the engine completely the same as the TT 2jz? just different inlet/injectors/exhaust?

[nevins]

they blocks are very similar fella, just a few things different on the block, but the head, cam cover, cams and alot of the ancillaries are not the same.
