Well it's finally happened, my stock turbo started to show signs of harsh treatment:D

I lost about 3litres of oil since I serviced it last, about 5000kms ago, and therefore did a leak-down test, expecting a broken ring-land, but the engine was fine, so it was down to a turbo seal.

I made the decision at lunch-time today that I'd replace the turbo, and at about 3pm started work on it. By 5pm we had the turbo and manifold off. I already have the turbo (GT30), and external wastegate(45mm), the manifold should be ready by Monday.

I'm sending the dump, manifold and exhaust housing to be ceramic coated. Putting in bigger injectors and fuel pump.

With luck, and all going well I'll have much more power for the drift day, and a car worth putting on the dyno for PAS.

Looks like my dreams of 12's on the stock turbo are gone, I might aim for 11's now:D

The wastegate will be off the manifold, and will be dumping to atmosphere like they all should:D

I wasn't dissappointed about the stock one dying, but would have like to have run a 12 with it, but with sticky tyres and 400rwhp I'll try for an 11:D

400rwhp??? please don't tellme you are going to go for that on stock internals and injectors or you will be up for a mortgage onyour car like SLY at the moment! i hit 295 then all that funny stuff happened as your well aware!..... we think it might be the valve spring, pistons look ok but a few signs of wear... hmmmm with 400 rwhp i might be able to pull a 14.1 HAAHAH!!!

let me know how you go dude!!!

Guest IHaveAnR33

i have an R33 stock hasb't had many mods at all 30,000 on the clock but only running very low boost about 3-3.5 a friend had a look under the bonnet and told me it had a boost restrictor. unplugged that and it was running 7 psi now the car runs odd. Splatters a bit, when i accellerate some times it is smooth and after a while it feels like the car is running almost like it has dirty fuel in it. would i need to have the car tunned in after bypassing the restrictor??

Are you talking about 7 on the stock guage? The stock gauge isn't in psi it's in 100mmHg, therefore 7 is actually about 700mmHg, or 1 bar.

The reason it splutters is due to overfuelling by the stock computer as you have raised the boost, it's very common.

BTW, if you want anymore help then start a new thread.

I just came back from visiting my car. I could have had it back tommorow if I hadn't decided to get the ceramic coating done, but never mind:D

The manifold is complete, with it's 45mm external wastegate. A new dump has been made, and a few changes to the intercooler pipework we're necessary. We removed the ABS to better position the external wastegate. The dump, manifold and exhaust housing are off to the ceramic coater tommorow.

The Bosch 910 fuel pump with surge tank is going in tommorow. Still waiting on a fuel rail to put the 550cc injectors into.

    • I have seen a case where the starter motor shorting against the casing caused a massive voltage drop + so much EMI that it caused all the sensors to spew garbage data at the ECU. Test the battery to make sure it has acceptable CCA/capacity first, I have gotten "brand new" batteries before that couldn't even power a 10W light bulb without dying probably because it sat in a warehouse too long without being charged. Only easy way to diagnose this 100% is put an oscilloscope on the battery and also look at key sensors to see if there's any clues.
    • There's a bunch of smaller shops that don't quite attract Singer money but are still hiring from that same pool of labor. Those are the body shops that you go to when you can't afford a Singer, but your old Porsche needs some serious bodywork. You can't exactly take those cars to the usual insurance body shops. When I say restomod, I mean they'll do something other than 100% OEM/OEM-equivalent aftermarket parts R&R. In the Porsche world this would be stuff like taking a 50k 964, doing a bunch of deferred maintenance/unwinding the nightmares the previous owners did to the car because a lot of people that own these cars tended to be penny wise, pound foolish types, then maybe some relatively simple off the shelf modifications to things like suspension, transmission, engine, headlights, etc. and you've spent 130k USD. When even the worst houses in the poor neighborhoods are worth 1M USD and the nice houses in wealthy neighborhoods are worth 3-10M USD suddenly 130k spent on a 50k car seems cheap.
    • Hoping to get a few ideas to help troubleshoot this issue, I'll try to keep it short.  A mate popped the motor in his 2018 LDV T60 with the 2.8 turbo diesel motor. He swapped it and I was his phone a friend when he got stuck.  The new motor is in, however it won't fire. The battery is literally brand new, when you crank it the volts very quickly (say 2 seconds of cranking) drop to 8 volts and the engine stops turning over. Watching the belts, I'd say they move about 5cm before coming to a stop. We put a booster pack on, no change.  The only potential issue I'm aware of is, when we pulled the motor the grounding strap was still attached. The strap copped a thrashing before we realised what was going on. It looks okay-ish but it's going to be replaced to rule it out.  The main challenge is, I wasn't there for 90% of the work. This is his first time doing any major work on a car and he was learning as he was going. He thinks everything has been put back together properly, however I'm not entirely confident that this is the case.  It would be good to get some ideas about what else to check. The car isn't spitting any codes so that doesn't help.  I've attached a photo, because why not lol.   
    • I mean an N1 came with a minimal paint thickness compared to dealer models. It’s probably had a ton of vinyls and stuff possible a race paintjob or two over the years. you don’t buy an N1 for its stunning good looks or comfort 🤣 you buy it to send it and measure how much air you can get on the hill at Bathurst
    • Yeah, but "restomod" implies Singer and things like it, which implies drug money / trust fund maturity.
