E36 3.0 ITB Race Build

[Rob]

I'll aim to put something together once the turbo is done and tuned (in a few weeks), i'll post in here wherever it ends up being 👍

Packaging has been interesting to say the least, plenty of thought required but everything worked out...

I kind of like the evolution from E36 to this, makes for a good story

Mapping happened

Track day happened

Everythings been hot

Changes have taken place - now for a couple more days over the next few weeks 🏁

 

[Matt Cup]

Any vids? 👍

 

[Flob]

Appreciate the time you took to create that update mate

325bhp at 4psi and 385bhp at 7psi it made.

Ill probably upload a clip this week 👍

Stock it did 242hp, esentially the book figure for the engine.
Then as above, here is stock vs 4psi, albeit with 50C, intake air temperature.

Since spent the past two weeks putting together a big cooling system for the charge cooler, with two more radiators up front, bigger water capacity, high flow pump to get some more realistic temperatures.

Very nice work indeed Jord!

Done 3x days with the turbo now. These were the most recent two. Been mainly running it on 3psi as its a good match with the E46 (well I keep going past ~6000rpm), with 7-8psi on the button if I want it.





Have made more changes, just two more days left this year, but all seems well at the moment. I've started sorting images out to put a thread together

 

[f0xy]

I'll be doing chronological updates on a new PH thread as and when I get the time in the coming weeks 👍

You could just post it to both… y’know, for the old school among us that remember your old grey Clio?

I know who the OGs are 😉 Mad that thread has over a million views now.

This thread is ahead of what I've managed to write up so far anyway.

Handy it can all be dropped out as a complete setup, few niggles resolved and going back together for 2026 💨

 

[f0xy]

No idea why they went as attachments and didn't insert 🤦‍♂️

 

[f0xy]

2026 started well 🤡

 

[Flob]

Ouch, worked out why yet?

Well DET killed it, due to oil ingestion, but also an issue with knock control (which would have prevented it). It's a long story and probably easier to explain at Cadwell in July if you're interested!

Spare engine is built up and ready to go in this weekend 👌

Before Oulton, I got it on the scales post-turbo to compare the weight to pre-turbo - only added circa 25kg overall.

 

[Flob]

Look forward to it. I couldn't see the piston tops but assumed ringland failure to stock ring gap.

See you at Cadwell!

Just watched these again. It's properly quick!

It's a good level on both base (wastegate) and 7-8psi, I've added flex fuel over winter so I can run a blended fuel, but ran out of time to get back to the dyno to tune that before the above. My plan this year was to concentrate on the set up more, as it had been good for 6 days in the back half of 2025 with the turbo.

At Oulton it happend mid afternoon, now I know, the damage was done earlier in the day - I was already bleeding boost into the crankcase (via a cracked piston) on an out lap, this then rose rapidly and blew the cam seal out when the piston finally gave way on cylinder 6

 

[Flob]

What a useful sensor on a boosted engine!
