That doesn't count it's going down hill all the way :D
Plus it's 1.8 not 2.0

So what mods do you have?

MPI, evo 2 turbo, 3inc exhaust, evo i/c, 510 injectors, link g2 ecu. also rebulit engine, all work done by myself, any of you kiwi boys want and mitsi engine bulit, im happy to help :D but as i said earlyer, bottom end and head bulit to standard spec's, i have another engine im installing whitch is 2l with late model evo pistons (evo 8) witch has compression ratio of 8:1, idea is for just afew more pony's to crack the 200kwatw's

Modify the engine and add nitrous then you will get over 250kws, get a Zex wet nos kit that has 55, 65 75 hp jets, easy to install, best bang for your buck.

Old Farts made 250 at the wheels on his jb pistons, which were installed over a decade ago. Here's the dyno

Yes but I believe this was with a modified head?

Do you have an engine bay picture you can post?

now, you may think... thats a fwd engine coz of the roccer cover but i just changed it so the writing goes the same way as the inlet manifold, its untidy i know but they were taken just after the wireing was done..

Hey, how much was the injection perfection custom dizzy.

Yes, correct, but nothing over the top. IIRC O/s Inlet valve and a mild Port.

Looks good.
What fuel were you using for your dyno run?
Also what cam?

My point was typically supporting modes support more power but you normally hit a brick wall somewhere around 225wHP (167wkw) with the stock head?
Yours is the highest dyno sheet ever posted on Austarion with the stock head.
How does that dyno compare with a Dyno Dynamics dyno?

i think the point of posting oldy's dyno sheet was more so about the fact it has still got 10 year old (albeit ceramic coated) STOCK CAST pistons in it.. not whether it has a ported head..

Stock head, no porting, stock cam, 98 octane feul, very similar dyno to dyno dynamic's roller dyno... i think the whole point of this is that people to easily discard the mitsi single cam engine for the twin cam, my car is on full boost at 2 750rpm, and pulls like a school boy right to 6 000rpm, i have put most model evo's and sti wrx's to shame, its quite a laugh, typical things they say after is "mean vr4 engine bro" "what type of nissan engine has it got?" or just the finger... hahaha

That's certainly a good result. Yes the spool and response using the EVO2 turbo (same internals as my EVO3 turbo) is totally awersome it just transforms the car.

Yes that's right I just added that without modifing the head 250wHP would not be possible but I have been proven wrong by our NZ friend.

250hp on stock block?
