Installed the new engine into the car on saturday and it runs fine. Cars driving and seems to be working good, except.......

When you put your foot down the car boosts way to high, it hit 1.8bar when I put my foot down so have only done it once way to much boost......it drives fine if you dont put your foot down hard and its still got the boost restricter in it so it should only be hitting 0.7.......Any idea what would cause this?

Fane suggestes one of the actuators on the turbos?

Make sure the boost controller is connected..  could be a simple thing like that..

I dont have a boost controller it just runs stock boost through ecu atm. Pretty sure its actuator, am going to work on it this weekend, out come turbs and pipeing again.......

Pretty sure you can see if the actuators are working on the turbs without taking them apart.. you sure the stock boost controller is hooked up properly, I only suggest it as having no solonoid working will cause stupidly high boost pressures.. if not my bad and good luck pulling it apart again.. :cheers:

Cheers

cant believe you got all the way to 1.8

on a new engine?

How about backing off when it passes 1 bar next time, or even better when it just gets over stock boost

This doesnt help me solve my problem......

We didnt know it was broken, just put the foot down, doesnt take much time to hit that kinda boost, i watched it climb to rnd 0.5 bar i wasnt driving dad put his foot down then I told him to stop.

If you must know we didnt know what to expect or to do to fix it really which is why i've posted here. Now we know what to look for wont happen again.

    • Yeah, the thread is only nearly 20 years old.
    • Been down in Tassie for 2 weeks (a cruise, not a race for once) but spent a little time on her when I got back. I worked out the injector settings in the PowerFC were not correct for nismo 555s, set those to 66% +10ms and added a little air at closed throttle, set the timing (approximately, because it has some weird non 15o cells around idle) and now she starts and idles properly. She purrs like a kitten (ignore the co2 alarm in the background, I did  ) 20250518_171052.mp4 Next step, off for run-in, tuning and alignment!
    • Went to a drift practice day at a local circuit (held on the reserve parking area behind the grandstand) for the first time in about 15 years. Some kei cars were drifting as well, a not so surprising Suzuki Carry truck, and two 1st gen Daihatsu Copens that were converted to rear wheel drive(!) using Daihatsu Boon X4 transfer case, prop shaft and rear diff, obviously omitting the front driveshafts. They looked really fun to slide. I heard that they cost "about half" as much as a Nissan Silvia etc to run.  On the track 'Tech M' a local BMW tuning garage had a customer track day. Mainly recent models but there was one E36 which looked ancient among all the current models. It was cool watching the drifting and then turning around and seeing random people thrashing their M3/4s  central-circuit-drift-practice-2025-05-18-long-yt.mp4
    • I prefer it with those wheels (sacrilege?) 😋 Here's a photo of a fully original one for reference. The price is $350K....
    • I would like to keep it around 15k but if I need more to make it reliable and not have to worry about the car breaking I can go more. It's my project car so I'm just trying g to figure out what needs to be in it i know basic things like turbo cams injectors I'm just unsure of the size and the specifics so I'm spending alot of time on Google and its mostly rb25 and rb26 not alot on neo
