16v Cupra

[V666]

Im glad you guys have got the know how, cause Im sure Ill have more and more questions as the build continues. Ive started on a list of performance parts needed hopefully to be achieved by early next year as the budget (read as other half) dictates. Apperently its not a sound investment or something?Anyway

-Jenvey direct to head ITBs 45mm, with injector size unknown at present, more reserch needed as is the fuel pump.
-Some serious head work
-Kent cams 296 duration (3000-8000rpm) 11.3 valve and cam lift, with associated cam followers pulleys etc
-JE pistons and Pauter rods specs again unknown, but Im sure theres brains to be picked!
-balanced, knife edged crank
-4 branch exhaust manifold supersprint stainless
-2.5" straight through exhaust with rear muffler (need to find out emission law?)
-mega squirt II v3 and a ton of wiring issues Im sure.

Anyone know of a good electonics guru as Im sure Ill need one!

This combination is amazing. Been using these two brands for many of our engines. Your rod lengh will be 159mm if 9a?

Cheers anything else you recommend to help keep the strength in the bottom end.

A standard bottom end will handle 8000rpm. just put a decent set of ARP (or equivalent) rod bolts in it.

Biggest problem I see with converting to carbs would be ignition control.

You'll also need to figure out how you're going to get fuel out of the tank.

Very true, Pete. Some people miss the basics..

If your going this far with an engine, why not spend 800-$900 dollars on Pauter Rods? PS: Pauter rods already come with ARP bolts.

badger5.com is where i would buy iTB's from. Bill really knows his stuff and i am pretty sure he will hook you up. tell him i sent you

[V666]

Nice one Velly thanks for the advice. Remember seeing his Ibiza what a noise!! and the speed!

[Water Boy]

For some ITB action and fueling etc.

Steve newing is rad bloke. My olman has run some of his stuff:

Throttle Bodies, EFI Fuel Pumps, EFI Regulators, Wolf 3D Engine Management Systems, EFI Hardware

For injectors etc:

Powerflow Performance

My Dad has run a lot of there stuff and recomends highly.

It Aussie made and buildt here in Eastside Victoria.

Just a word of advice mate.. Listen to Velly (he has been there and done it- Along with countless mates of his..) and Waterboy (his old man has been there and done it, and still is).

You'll find that some people give out a lot of advice when they have no personal experience.. Take it or leave it, just saying...

[Kiel_GTI]

I'm not backward in coming forward. Deal with it.

someones been drinking too much hateorade.

OP: project sounds the goods mate.

[V666]

Cheers James will defo look at their stuff as your Dad recommends them! cant say better than that. I hope Velly wont mind picking his brains, now I know his done it all before.

So standard rods will be fine, just wanted to make sure the cams will be utilized too their full potential and didnt want problems with a weak link in the mix revving out to 8000rpm. But if 350bhp can reached on standard rods with ARP bolts then mine will be fine, not going anywhere near that high!!

By the way really appreciate the help and suggestions guys.

I'd at getting a local ECU perhaps, as opposed to megasquirt. MS is all good and well, and fun if you want to play with it yourself, but if you run into troubles there isn't any local hands on support, it's all online. If you went with a local ECU (microtech, autronic etc) you'll have much more local support when it comes to fine tuning and troubleshooting.

everything else sounds good though

I'm assuming you'll be looking at doing the box as well? diff?

[Preen59]

Actually people make 350 odd hp on bog standard rods without any problems. Also, Colin Gyenes' (works for Techtonics Tuning) Mk1 Rabbit drag car used to turn over 9k sometimes with zero failures.

When i spoke to them about my engine, Colin said "how hard do you want to rev it?" so i just picked a high figure out of the air and said "8500rpm" and without a pause he said "Standard rods and pistons will be fine.."

Running decent rod bolts is just good insurance, really.

Nothing like that dude. I'm just sick of people with no actual experience or knowledge steering people in the wrong direction.

In regards to the fuel trimming and tuning. Either use a system where you know someone local who can tune it, or if you are an IT type, get something easy to program and tune it yourself. M.S has a good interface and has good documentation online of what sensors you need and how to set it up.

I agree that leaglly you will not be able to register the car with carbs and pass emmissions.

Megasquirt on ITBs would be emissions friendly, and not that hard.

Send a message to pepperwhite, he has a 16v on ITBs and M.S in a Mk1.
He wired it all up himself and hes not a techie.

Also have a couple of Diesel Gearboxes that have the ratios to make a 16v haul ass. Straight bolt in for your car, hit me up if you feel the need.

[velly_16v_cab]

love that link james (waterboy) put up. that is a starting point and the prices arent to bad either!

if your going to mess with your gear box and get an LSD fitted look at changing the final drive to if you can afford the extra money. An LSD is well worth every penny if your using the car on a track.
