Your path is different from most. Stages are defined by canned tune vendors. Once you go custom, there is not a stage definition. Currently I'm running a 1.8t with upgrade main bearings, stock caps and bolts. IE rods, wiesco pistons. Head is built with super tech springs and retainers Ferrera valves and stock cams. ID1300 injectors, pte6062 gen2 and custom 3" exhaust. Aem400 fuel pump and snow water meth. 562hp on 93 octane. I did most of the work myself. Alot can be left stock and a 2.0 stroker set up is not necessary. The motor does not mind 350hp stock, but it has to be tuned to limit bottom end torque. If you do build it and have nice bottom end torque, or go 2.0, build the transmission. That's where the bulk of the money goes!
I’m looking forward for more videos. I just got a MK4 GTi 1.8t and it’s going to be my daily . And I want to upgrade parts . And at least have between 350 -400 HP .
Not all engine codes have forged cranks, and the big port heads dont need porting but the small flow ones would benefit but depends if you want high or low end torque. When it comes to the rods you should be stating the torque figures for breaking point not the horsepower. I look forward to seeing your build in future videos.

@@Sk0die Hi there No the turbo fits on the standard manifold and exhaust fits on the turbo so no changes/modifications. I bought i slightly used turbo. Still fine after using it for around 4 years now.
I really enjoyed your vid. If I may ask an off-topic question, what wheels are those? I have been searching everywhere for some but cannot find any 5x112. Much thanks.
Nice video but the first thing one should do when they wish to add more power to a car is upgrade the vehicles suspension and braking system as failure to do so will cause the car to just crash as it simply wasn't built with those power levels in mind. I can't tell you how many people I've seen the did thing backwards and ended up crashing the car when they were out having a bit of fun. As a rule of thumb start with the vehicles suspension system, them move on to the braking system, upgrade the seats is also a good idea but it's not required. I took a VW Scirocco to new levels by doing things this way as I was suddenly able to corner like a boss and stop on a dime. I replaced the springs, sway bars, each and every bushing, even on the steering rack. I mean everything was changed but I stopped short of getting a roll bar. I put on upper and lower stiffing bar and another one on the shock towers in the rear. Then I got Bilstein shock absorbers front and rear, with some racing brakes slotted and drilled. I updated the master cylinder and vacuum chamber and went on to remove every piece of rubber replacing it with polyurethane. I had to have some specially made sway bar mounts as the one's that came with the bolt on kit were trash. After I was done with all of this then I went on to upping the power to the point where my Scirocco could take on 911's and win. Sadly I had to get rid of the car as VW refused to give me any support for the aging Scirocco as it needed a wiring harness and a few other things due to being driven all over the USA as I took that car coast to coast several times and even down into Mexico and up to Canada. That car was just so fun to drive but without manufacture support on getting parts I had no choice but to have the car crushed. The funning thing was VW wanted me to buy a new car and I told them that with they way they supported me as my car got older I'd never buy another one of their cars and thus far I have kept that promise.
Hi, yeah this video was more focused on the motor its self, and what can be done to the engine to make some power, as well as where the weak points are. But i agree, if you make alot of power you need to upgrade the brakes, wheels and suspension 2. 😅
Great vid Chris. I own a mk1 audi TT with the BAM motor. I'm looking for some advice im struggling with a over reading knock sensor and the boost seems inconsistent with lackluster timing. Car has a ramair intake, k04 turbo and twin intercoolers. Any suggestions on who to speak to?
In my case, the transmission is the weak point. My 2015 VW Golf SportWagen 1.8T has an IS20 turbo upgrade and tune, but the transmission doesn't handle the extra power well and will sometimes kick the car into limp mode at the 2nd-to-3rd gear shift point during a hard pull. While the tune is nice, no one makes a TCU tune for these FWD 6-speed Triptronics. The workaround is to let off the pedal at the shift point and stomp on it, similar to a manual shift
for decent 400hp just have - 1000cc injectors, 300-400lph fuel pump, rod and rod bearing, ARP kit, Bigger turbo 30xx gtx, westgate and blowoff, SMF 240mm and rs4 clutch kit, in long run youll fix more weak pints so as gearbox :) and shifter

The pistons are only good on the BAM engine!!!!! (225hp S3). On all the rest engine codes they are good up to 350 but again it depends on the tune and how offensive it is.
For a very Streetable engine, how much power can be made without adding boost lag? Right now, power kicks in by 3000 rpm. I wouldn't mind that happening sooner. Or how much power can i make without adding more lag? I'd rather have 250hp at 2500rpm (if that's possible) as opposed to 400hp at 5000 rpm.
