13.6 with 160kws race suspension awesome.
Whats the torque figures Stu?

13.6 with 160kw (218 HP) is good but not awesome.

A 1200 that's 250 pounds weight over stock should do 13.0 with 218 NET HP (as the auto manufacturer's measure HP). The race suspension might loose .6 seconds, so that makes it good.

With 218 RWHP (as measured on a car dyno) should do 12.4 seconds. Losing more than a second could be due to the traction + gearing that is not optimal for acceleration. This is to be expected from a car not set up for the 1/4 mile.

Has Ruredi weighed his 1200? If it's lighter than my assumptions, it should be even faster.

Z-head in stock form outflows an L-head in stock form is what I've always heard. But the L-head modified can beat a Z-head modified. Is that not a true generalization?

Ok well I'll say 200KW ATW is my target.

From what I know, the combo suggested should be more than capable of that. If anyone can suggest an option better then as I have said (taking into account weight, cost and ease of conversion)...I'm all ears?

At the moment it's the clear choice as it ticks all the boxes for my requirements.

I did that time before exhaust and ignition upgrades so would have had less power then. Cant remember torque figures D il check my dyno sheet

I also just wanted it to be know that my z18 picked up most of its additional power due to an exhaust manifold that Leigh designed and built. So clearly he has some idea of how to do things D?

230+ Kw @TW is alot of money. That's 400HP @ flywheel. Think about what you are asking from the motor realistically. I'll give you one of Morrows secrets for free. His is a L18, still a 1.8L. Not because he is cheap but because it works. Combinations sound great on paper and are great to tell your mates this or that but it is all wank when you introduce a turbo. The megre gains of combinations are trivial to a street car in my opinion, and this is not just my opinion, but the handed down opinion of thousands of HP hunters. The blokes who need to get the extra power have maxxed out their race car and are searching for every extra Kw they can find.

Remember the KISS rule. Keep It Simple Stupid.

Here's another free Morrow engine tip. After a few different camshafts, Nizpro found they could get more power from a standard Z18 Turbo camshaft. It's all in the turbo choice. And bigger is not better. A good T25/28 Ball bearing turbo will spool up nice and fast and give a good power range.

And as Stu has pointed out, there's good gains in the exhaust manifold. Choose the right bits, based on what makes a good combination, not what some d!ckhead down the pub tells you what is the shazizzle.

Torque is what these engines do well and with the right snail will be very responsive, will be good to see a before and after stock to equal length setup exhaust like Stu has done but with .48 ex and .60 Ball bearing setup. I wonder if one of those George Fury exhausts is still avail. for sale in Ozdat from someone? it looked well made.

The L16 block will handle the L18 crank straight in so maybe the L20b crank is not required? Don the L18 is shorter so timing case height needs reduction.
Do you recall if it looked clean and well done or didnt notice at the time due to too much beauty to look at?

Ruredi call Sanjay, fill in new rules then teach us whats up.
Stock cam saves a fair chunk and Im guessing Mr Morrow has
gone bigger nicely shaped inlet valves and larger inlet ports? as the exhaust ports are pretty good already with just a clean up, they sit higher than inlets surprisingly.

With the stumpy combo 850kg and possibly 200lbs of torque should be good but Don is it possible you can find if the early 2.9 or whatever it was in some Zs is still available and able to replace the 3.25 1st gear? would make for better take off with all that torque and lightweight.

Ruredi,roughly how much do you plan on spending on the engine build as this will give an indication as to what engine combos to limit to a certain budget.

If willing to take a considerable time working on vehicle then the following engines could suit.
if after 200kw atw, maybe an sr20vet 280bhp stock! and f20c naturally aspirated 4 banger,240bhp stock!(bhp is at the engine hp)then work them up abit.Stock reliability and durability.i know u have stated not after sr or ca but just giving you ideas based on 200kw achievement.bro is planning on an f20c convo into a corolla in the future as btw 250-300whp NA stroked is achievable.also not as common as sr/ca.

Best option to modify and keep ur a series mate....

n btw,

i learnt this last cruise from a ride in the green trueno.i definately would have asked what engine and suspension he was running as the car handles like on rails.In the twistes ,light cars with mildly to worked na light motors would leave many cars for dead!!Also didn't experience any body roll. i've been in quick turbo cars before but never been in one that could handle and turn as quick as this NA trueno.Engine Weight is a very big factor if after handling and hill climbs or mountain passes.

Only problem with f20c is that the exhaust is on the drivers side no way it will fit without putting a steering rack in.
