The benefits of upgraded Intercoolers

I'll be getting my car back soon (thanks to Mr Duff) with refurbed standard turbo's, rebuilt engine with 88mm pistons, underdrive pulley, decatted, profec b etc etc.

I'm hoping to run the car at 1bar of boost - would I see any benefit in fitting larger SMIC's, specifically the Z1 units. I notice "Steve-300ZX" has uprated his intercoolers and acheived extremely good bhp figures.

What do you think?

the stock ic's are quite small & are pretty much at the max of their capabilities at 1 bar, so any decent uprated ones should see improvement.

Phil the reason why Steve has such good BHP figs is because he is running a Genuine Nisstek chip (not a copy) that was custom mapped for his spec.

I think Steve is running the most BHP on here with a standard engine.

If you are interested speak to AndyP I am sure he has the dyno charts to compare.

Well I thought things were going too well. The underside has come up well and is looking a whole load better now.
Turns out pre 2009 cars don’t need reverse lights to work to pass an MOT, so I can solve that problem another day. (Switch is working fine, but no signal getting to the rear)
New tyres delivered yesterday and I can just run them down the local fitting shop and have them fitted.
So I thought to myself, I’ll throw on the new pads and discs tonight, and she will be ready to go!
Then the brake pipe broke from the calliper and I had a sense of humour failure.

I was just completing my booking but realised that it’s one of my daughter’s 16th birthday! I’ll check what she’s up to and see if I can get a pass! She may come with me, but doubtful. Will update as soon as I know.

Check engine light comes on and off sporadic.

Those codes are all pointing at a related issue. A/F ratio falling out of range, heater elements within the O2's out of temp range, EGR sensor or exhaust gas temp falling out of range, etc. There is a few areas to consider...
Was any work recently done to the car that may have triggered this? When was the last time you replaced the O2 sensors? Check the O2 connectors and wiring to make sure one of them hasn't contacted the exhaust or melted. Any exhaust leaks especially before the cats? When was the last time you performed an induction service and cleaned the intake, TBs, IAC, etc? The EGR and IACV love to get carbon buildup over the years and can affect flow, similarly can happen to the vac lines to the factory wastegate control solenoid. You mentioned the car felt like it was still running well, so no idle RPM fumbling, hanging, stumbling, etc? Are you running an aftermarket boost control solenoid or OEM? Sorry for the load of questions, but need a bit more to go off of to help point you in the right direction.
Even though the vehicle has considerable low mileage, it's still 30 years old. If it's kept in a garage it tends to handle the elements better than sitting out in the external environmental conditions and will need more routine maintenance and care regardless if it's being driven or not. (i.e. 60K / 120k maint w/ timing belt)

Check engine light comes on and off sporadic.

Hello, I have a 1996 twin turbo manual with 64k miles. I recently started having the check engine light come on sometimes and other times it doesn't. When I checked the codes these are what I got : If anyone has had these same codes what did they change to fix the problem. Car runs fine with check engine light on but want to fix issue. Any help would be greatly appreciated. Thank you.
