Plenty of ibizas/golfs going about with 340bhp on standard internals

The Chief

I'm not saying there isnt i'm saying the S3 and the 225 Audi TT have forged and stronger internals

Mitchy260

LCR also

Yes ive heard the AMK/BAM 210/225 engines had ''uprated internals'' from the 150/180bhp variations aswell but i dont know if there is any truth in it as jabbasport reccomend changing rods on all 1.8T engines at around the 340bhp mark.

Yes even on the 210/225 engines (Jabbasport are top 1.8T tuning specialists)

The 150/180bhp engines have proven themselves just to be as strong as the 210/225 lumps.

Here are a couple of guys that have run stock internals with 340bhp IHI conversions from 150/180bhp based engines without any modifications to internals..

Engine Internal Work - SEAT Cupra.net (Post 13, badger bill, currently on 527bhp with ibiza although he has had uprated internals installed)

Not well up on the Seat range but the LCR is basically the same unit so yes pretty big hp is achievable with this

Its all in the right foot, the accelerator isn't just stop and go

To get big FWD power down on the tarmac, you need to part throttle 1st/2nd gear just below the threshold for when wheelspin occurs. It takes a bit of getting used to but you'll figure it out in the end. Yes if you go straight away full throttle, like you would in a scoob/evo you will light the wheels up and not get anywhere very quickly.

However once you pop it into 3rd/4th, and then apply full throttle action, boy do high powered FWD cars fly No 4wd tranny losses slowing it down

Mine's a Jabba IHI, i.e. a bigger turbo (and some other grubbins). Not changed internals (yet), and even the gearbox is still standard. Dyno'd on jabba's rollers at 337bhp

Wheelspin can be had very easy, and you have to change the way you drive. Traffic light grandprixs are no-no's, unless you accept that you lag behind before you are able to bury the pedal. On the motorway however it is not an issue

Mitchy260

Jabba IHI conversion including mapping and labour is about £4500. Will get you upto about 340bhp

This includes turbo/manifold/downpipe/injectors/MAF/Fuel pump/TIP and all the other little bits and bobs oil/coolant feed+return lines, gaskets etc

It depends on the base model car, if its the 210/225based cars, you dont need injectors/fuel pump/MAF/TIP etc so will be a little cheaper.

A standard 180bhp K03 turbo wont get to 260bhp im afraid, probably about 240bhp max. You need a turbo change to go beyond this on the K03 based cars.

260bhp FWD power is comparable to 300bhp 4wd power on the move when traction is not an issue (given weights etc are around the same) so they are certainly not slow

Mitchy260

You will need the stage 2 map and it involves all the other usual mods. Full exhaust/induction and 4 bar FPR. (FMIC is optional)

Yes your right, the remap gives you a good jump but the rest of them coupled together dont give that much in comparison peak power wise. Although driveability and power/torque through the rev range is improved more than the peak power jump suggests.

I dont think decatting works very well on the 1.8T. Gone are the days where you removed the cats and gained 25-30bhp. Probably 5bhp max on 1.8T.
Better off with a sports cat, saves messing around MOT time.

My friend has a mk2 rallye golf with a 500bhp 1.8t engine in it

Mitchy260 (do I know you?) has pretty much given you all the answers. In all fairness I had it the easy way as I bought the car from a friend after I couldn't find a replacement big enough inside to replace the Octavia vRS I had previously. The bill was a bit higher than £4K5 though (not for me fortunately ). It was more in the region of £6K including labour, brake upgrades to match the performance, suspension, etc... and no end in sight yet if I want to push it further

Fully agree on the 260bhp issue... I'd also say that 240bhp is the max you can hope for without replacing the turbo. If your car is standard, plan everything carefully, and save up some good dosh.

If you pop over to BRISKODA.net you will find many thread detailing the issues that you're concerned about.

Q.

Quinten

Forgot to add: Quintens Octavia vRS - BRISKODA - The Skoda Forum and Community has all the things listed from my car.

Monkeybone

Also forgot technically the 210 version is a little stronger I believe as it has 19mm rods rather than 18mm rods that are used in the 225 models.

From what I've been told by some people hwo deal with these engines.

Mitchy260

Dont really use the Briskoda site mate, although i am registered on there. I only really use the seatcupra.net forum site. If you use that, you'll know me as mitchy on there

Mitchy260

Its the wrist pins and im sure its 20mm vs 19mm but again its not known if this information is correct. Im sure it started off in speculation!

Still the engines are reccomended at 340bhp for rod change. A lot of people will keep the standard pistons in and just uprate the rods.

Monkeybone

I knew it was something but couldn't remember what Just have heard form numerous sources that the 210 is a stronger lump, but tbh they are all going ot be pretty much the same.

Quinten

Ah, in that case I do not know you

Quinten

TBH, my previous vRS was just remapped (216bhp) and that was already a much more driveable car than standard. Not got a clue on what classic scoobies (or any scooby for that matter) are like to drive so can't really give you a fair comparison on that. Plenty of ex-scooby owners on Briskoda though

matchmaker

My Octy vRS is remapped (by Star Performance) and also has a Milltek cat, Supersprint exhaust and CAI. Puts out 231 bhp but more importantly nearly 251lbf of torque from about 2000 rpm.

TLGP's are a bit of a waste of time to begin with, but once you're in 3rd it's game over for lots of the opposition

I can recommend both IP (not been there myself, but know lots about them) and Jabbasport (been there, done that, have the t-shirt ), so whatever you end up with, it will sure to make you smile
