Celica Gen 7 Turbo/supercharger?

[KB_]

One of my friends have a Celica T23 Turbo based on the 140bhp celica..it got aroung 225bhp with the turbo and its a amazing ride now, drives very well...

I was wondering..is there any T23's in the UK who tuned like that?

[DefiantFrog]

Yep, there are instances of both Turbo'd and Supercharged G7's (assuming this is the same as the 'T23' you refer to!) in the UK. From what I understand the Turbo'ing isn't quite as easy and reliable as it could be, and supercharging is probably a better way to go...

You'll probably find more info in Celica-Club if your after specs and stuff.

That looks cool.

Wack a turbo on the 190 lump though... more work... but more rewards in the end.

Have a look at Bubba's:

FI rocks the 140, the supercharger is preffered by some, but a good turbo is more aggressive. :D

[Crisis]

Love it!

That was at Japfest wasn't it, for sale I belive!

Wouldn't a 190 be better as a basis though?? Surly a turbo could fit on, in somehow?

Love that kit mind, not sure about the colour thou.

[gordypix]

Yes he is selling it.

I think the colour is very catching especially in the flesh and yeah the kit does look cool

Wish I knew how engines worked and could afford to whack a tubo or lil sumthin' sumthin' under my 190's hood...................

we really need to discuss the 190 more and FI application. it's not impossible with research and cash - i'm sure some USA guys are pushing FI lower in the power band.

The lift is designed to mirror a turbo at 6K rpm, how would you like that from 3K rpm - would be nice wouldnt it, you know it makes sense, it takes research and understanding the stock and anything is possible.

I have identified why it would cause problems on a 190 - we just need to work around the problems to find the answers to make it practical and usable without negating the inherant characteristics of the lift function as its designed to be used in a limited fashion.

Lift bolt failure has been identified, so we know theres a weakness, although toyota say they fixed that problem.

If no body researches and devlopes ideas then the gen 7 in general will remain largely a NA principal.

cheers.

FYI Blitz do a full supercharger kit for the 190 ;)

Extract:

A recent addition to the Blitz range is the supercharger conversion kits. These comprehensive kits are easy to install as the superchargers are self-lubricating so there are no oil ways to attach. The kits are supplied complete with all fittings and in most kits a front mounted intercooler is also supplied, for JDM cars a fully mapped ECU is included. Applications are for Toyota models at the moment (including the new 190bhp Celica and Toyota Altezza) but a Mazda RX8 version is to be launched soon.

Edit:

RRP = £4,478.00

there's a SC'd celica down this way, full blitz kit and it sounds awsome! it's got some kind of wierd recirculator that catches everyones attention for the first 5minutes then it's just another car that makes a noise :P

check the funky styling site, they've got the kits listed IIRC

thats an expensive strap on blower - obviously of the highest quality - I would very much be interested in reading there reaserch and developement particulars though with respect to the VVtli engine.

A supercharger apposed to a turbo would give a nice torque increase from the outset without being lairy and would be a great gradual increase in adition to the manufacturers base principals .

A Turbo on the other hand would think about it for a couple of seconds and then unleash hell to the wheels, obviously boost controlled and there would be limits for driveability - as its FWD a supercharger could be better from a standing start as a tubby might just spin the wheels in drag type scenarios when the clutch is released at, say 4000rpm. All boost dependant, progressive control electonically operated could be done - but expensive.

Without further info, I would definately want to be making more naturally asperitated power higher in the power band, unless they have development trials proving lift can handle FI, in depth trials - not just a shiny car on a trade stand. Tolerances are important to me and I like to understand limits before doing anything.

Afaik - the VVTi engines take much better to the power delivery of a supercharger. Because of the way the SC delivers the power the car retains most of it's original driving characteristics but with more power...

On the other hand the Turbo will significantly alter the driving characteristics because of the totally different power band.

As for how the Lift would be affected by this I'm not sure, but I would certainly think, if there was a weakness in this system, it would be the lift bolts. You might need to change the cam profile(s) as well to alter the stage at which the lift kicks in...

But then what do I know :)

[Cubic Incubi]

my understanding, which as ever is open for discussion on the Gen 7 models is that;

VVTi is a FE head.

VVTLi is a GE head.

turbo on the FE will not make a different power band, it will simply accelerate it and make it come in sooner due to the low down torque charegteristics of the cams, the only problem you have to consider is the volumetric efficiency beyond the stock peak power as you extend the band, and the thermal efficiency.

Turbo the GE and again, it will accelerate the characteristics of the power band and will make much more peak power, as long as the oil is good and the thermal efficiecy is adequate, the lift function will be safe. Oil needs to be highly considered as it is wrong choice of oil which in most cases kills engines, aswell as operating outside of the range of thermal efficiency.

is that any good?

cheers

it looks like theres a few driving over there then! :D

i know he says that its a totally different car now..hes more into the smooth driving not the revs like it should before..alot of revs before it was going anywhere, now he just pushes the pedal and the turbo spools up and off you go! :D
