hey guys just really getting annoyed with my car when driving it cold or even first line in dash water temp...

i just drive ok soon as i hit 3000/4000rpm just sounds like it splatters/hesitates, exhaust sound is like brrrrr brrr when between that rev range but when its fully warm no problem at all runs good...just dont get it..

any ideas guys cause have to always wait till it warms up fully and is a pain..

Well i just changed the turbo to slightly bigger and it is doing it all of a sudden never done it with the stock one... just when im about to hit boost which is the revs i described....

Under oiled turbo? u mean like no oil coming through or just takes a while to get oil in until its fuilly warm....seems like that.

your probably hitting R+R because its still cold and you have a bigger turbo

doubt its anything to do with turbo bearings being under oiled

not much you can do about it if you still have the std ECU, its a tuning thing

if it was the bearings it be stuffed and smoking and all plus i have a braided line which came with the turbo which was new and i have a greddy computer on it so im sure its a tuning thing as it wasnt really tuned only tuned for detonation as in power tune...its still ok but just takes awhile to warm up but i guess i can live with that for now :)

my r32 has the same issue exactly for over 6 months now. Stock ECU, stock r33 turbo. I had a TR43 turbo before but changed to a r33 turbo now - I've changed fuel pump, coil packs, spark plugs and O2 sensor, still there. Funny thing is, the issue goes away EXACTLY when the temp gauge hits half way mark - on the DOT!

any other ideas? :(

i maybe thought it was going into coldstart mode so thought it was the water temp sensor but guess not...like u said when its half way or at its normal engine temp its all good.....Maybe FPR or AFM...

Has to be ecu just going a lil koo koo until it hits its normal operating temp.Tune must be the last option i guess.

    • I have an Elite 2500, honestly most of this has been a lot of smaller tasks chasing little details and a whole lot of life getting in the way of bigger projects. I don't mind too much looking at a spectrograph vs having audio knock ears. 
    • Nah nah nah nah. Don't do it. It's not all about the full throttle power delivery. The main "street fun" and drivability gains from smaller rear (in this case) is how you will have boost available from a low rpm when yo just roll onto the throttle. Think jinking in and out of traffic, coming out of roundabouts, etc etc, where you just want to roll onto the throttle a little and have the spooly noise from ~2000rpm and a swell of torque. More of what you've already achieved by going to 2.5. And then, towards the tail end of 2025 you can pull the turbo 4 out and put in a V8 like we originally suggested. :P
    • Cheers for the info mate, I'm old too, 60 years old next May, so a more linear delivery of the 0.86 would be better as baking tyres and snapping heads isn't on the cards for me or the car I assume a more linear power delivery would be better for engine and drivetrain reliability as well, IRT the torque load at lower RPM???, as well as lower EGT's???, if my understanding of that is correct, have I got that right??? I've only got a really basic understanding of turbo sizing and all there characteristics  Cheers for the useful information 
    • What kind of power delivery are you after? If it's nice and linear, the 0.86 would be better. If you're after bake tyres and head snaps on boost the 0.64 would be fun. I'm boring and old, so linear power is preferred. Lately I've been watching videos on Z06 Corvettes and super charged Mustangs.... 
    • I’d go the smaller rear just because you’re staying on 98, if e85 I’d go the bigger one
