upgrade to the sbd tp148 throttle body kit, the install a low pressure turbo on your exhaust manifold.. looking at a nice 170bhp there.. Gonna cost u tho

Need medium compression pistons or two head gaskets! get ones with large pockets and you can put a cam in thats got more than 270 degree lift.

Ditch the EGR

4-1 exhaust manifold,decat straight thru.

With the SBD kit u get an MBE ecu and it can control a turbo.

Get the head gasflowed and ported, get uprated ARP conrod bolts and you can then rev to 7500 safely-ish.

Should cost roughly 2500 ish, strip the car out and youll be giving insurance group 17 cars a run for their money!

2500??? 3500 for turbo, 1500+fitting for TB, then u have to get an engine management system to run the TB and Turbo. Your looking more in the region of 7k for around 170bhp.

1.4 is a good little engine, but the 1.6 16v is far far better. If you like yuor car, why not just put a 1.6 16v engine in there? Much more tunable.

Or, a 2.0litre?

I wouldn't bother tuning the 1.4 16v though

Oh, Turbos don't work very well on the 16v engines. Too much work. And the 3500 Courtnay job is a farse. Total Con.

But corsas are great fun I love driving my car. When i took Lee's boxster out it was a superb car, but very smooth. D4 is just raw bottom end fun (shite at top end lol) and i know exactly what the car is doing and how mostly (but not always) manage to save arse end out stuff

Corsa B's modded subtle look great

the SBD kit is 2k roughly that comes with MBE ecu , wiring loom and throttle bodies, EASILY FITTED for free by yourself - just have a go!

I cant see why people dont have a go on their engines, you cant do anything but learn!

You can get a recon turbo of a specific size to ur engine for circa 400-500, then get your manifold custom made by an exhaust specialist say 300, tap an oil feed return in the block for the turbo. Get down to a metalwork fabricators to make your boost + intercooler pipes. Whip off the head, stick on two head gaskets = 80.

Thats 170bhp easy if not 190 bhp tbh for circa 3k.

You havent even looked at cams + exhausts and lightened flywheels, diff's etc etc.

The 1.4 is more tunable than the 1.6 bhp/

obviously the 1.6 will produce more power as theres no substitute for cc's.

gsi is group 11 mate on the insurance

Options:

Turbo
Throttal Bodies
Supercharger
Traditional tuning route e.g. cams, unichip, head work, manzal box

or a engine conversion, 2.0 8v, 2.0 16v, 2.0 turbo

all depends on how much money u got for the tuning + insurance

sorry for hijacking your thread mate

Artkart

What have you had done to get 125bhp from the Corsa and how much was it?

Also what are peoples experiances with products like Manzels PowerBox or equivilent (Lexmaul), is there any benefit to the more expensive ones like the dbilas that Regal sell?

Dont want mad power but 125bhp sound nice

Most people are not that technically minded, and doing a turbo conversion is bad enuff on the 16v motors, doing a home conversion is asking for trouble. If courtnay can't get it right, then i doubt someone doing there first engine mods can do it.

1.6 is the better engine to tune by far, no arguments there. Ther are none, it is better simply.

Lexmaul, i can't see how it can be any better, it follows the same air route as a standard manifold. Mantzel or Velos are much better.

Skippy, you are correct, same block, completly different bottom end. Costs as much to replace all that as it does buying a 2nd hand 1.6 16v engine.

Bastid, not over here, looked into it.

I still think ur better off with an engine conversion to a 1.6 or 2.0litre personnally (from 3 years experience with corsas).

U could sell up, but theres no fun in that. And ur only spend money modifying the next car. So why not just concentrate on ur current one

@KingCharles

I went to Mantzel Germany with my 1.4 16v.

Standard my car was rollerroaded and came due to Remus and K&N to 95.2 bhp, 126 Nm (sort of lb/ft, but please recalculate it)
I got a Mantzel Powerbox, rollerroaded: 115 bhp.

Then my corsa had a Powermotronik. That's individual chiptuning. Not a standard chip, but individual, adapted to engine characteristics etc.
Then I got some 125 bhp, with 140 Nm.

My corsa is really fast. Due to removed limiter from 6620 to 7500 rpm. I can drive 90 miles/h in 3rd, and 112 in 4th. Therefore a Audi A4 1.8T was either to slow driven by its driver, or incapable at 60-90 in passing me.

Before some guys tell me the Vauxhall engine can't handle 7500 rpm, or it damages the engine. I know that one shouldn't do it to often. The best way is to strenghten your engine with conrod bolts, maybe other pistons or something, but I don't know the exact English expressions.

I haven't measured 0-60times, but top speed is well above 125 miles/h (> 200 km/h) in stead of standard 180 km/h.

Cheers,
Artkart

Check www.mantzel.de for details or call +49 20 8850590 and ask for Mario Coric. Refer to me and my Corsa and he knows exactly who I am and what he can do for you.

Mantzel also sends Powerboxes all over Europe.

cheers for that mate,
problem is found mantzel parts
powerbox: 20 bhp, 475, 350 fitting
Piper Cams: 300 10 bhp, 150 fitting
cat by pass: 50,
Manifold: 350, 100 fitting
so thats 1175 parts, and 600 fitting

then i need a programmable unichip 400
The pipercross viper filter at 250

so all in going to cost around 2500 - just for bout 125 bhp!!
why dont i just buy a zetec s fiesta with 110 bhp standard and put in cams, chip, manifold etc??
im stuck now plus my car has bodykit and 17's, yeh i do love it but its more for crusing than driving
