Yea they are good to about 400bhp don't really want to go above that I realistically expect 370-380bhp the original 365 came about with hp pistons I have low comp in now but with better mapping with z20let ect and say 2.8" should be there somewhere.

[The Batman]

your head is fully sorted isnt it? valves, springs?

[NickB787]

yep I have a saab to put on if required, but 78 double springs saab turbo valves are you telling me to spend more? have you met the wife, come over let me introduce you

manifold is back on,

s/c to go on, crank sensor bracket to adapt for the z22se sensor. 2 teeth to remove, loom to fit, am still working on it now


edit


the m6 are made of cheese one of the only 2 I left snapped as I was tightening it up very little pressure, off she comes again

What grade are they? sounds like there isn't enough torque on the them to keep the load in the joint

im not good with wives i know too much and am unaware of the secrets that the vx members are keeping they are all interchcangeable in a matter of minutes so maybe start big and get smaller?

[NickB787]

couldn't tell no makings, but they were not good, that last one just snapped with a small alan key on it. if I did this had again, I would change them each time they were removed throw them way

i will get the oem off so it's easy to change in future think I will put the 2.8 on

[The Batman]

be interesting to see

[Exmantaa]

Looks like some silicon sealant has been used to seal it. will put some on just don't want to get it near the sensor.

what size pulley should I put on Joe?

Probably to seal the "too narrow" Courtenay MAP sensor.
The Z20 LET uses a Bosch TMAP sensor right? (0261230042) That should have a good fit in the mani (= std LSJ) but for the Harrop you need to mod the mounting hole and turn it a bit clockwise...

[NickB787]

Bosch sensor, not certain what the z20let uses, Courtenay's gave me one which is now fitted, and sits under one of the s/c bolts holding the snout on, shouldn't move. one bit of good news is that it's booked in Thursday not tomorrow, just hope I can get it done in time.

[NickB787]

will get a price tomorrow, although seem to be about 70ish quid

£65 delivered autovaux

wonder if I could cut the z22se plug of my old loom and replace the z20let plug?

[Muncher]

Keep going Nick, I'm following with interest!

[NickB787]

questions on the z20let it's single lambda is it post cat? whats the Atmospheric sensor? edit, the new loom has a single Lambda connector, wonder if I goes post cat? willl it matter only having one?

1 - mixture, before cat 2 - I think Jon is going to disable it

[siztenboots]

questions

on the z20let it's single lambda is it post cat?

whats the Atmospheric sensor?

two lambdas, one just after turbo , used for everything for actual running,
second lamda , just after cat, used for check system efficiency

iirc, there is a barometric pressure sensor mounted on the ecu

[NickB787]

1 - mixture, before cat

2 - I think Jon is going to disable it

1. being think here, before cat ?


2.good.

[vocky]

mixture lambda is located between the exhaust manifold and cat the one after the cat is just to confirm the cat is working

[NickB787]

Am going to have to swap the Lamndas over as the one post cat has the plug which fits the loom plug, shame.

[NickB787]

No I am not I have removed the pre cat lambda but can't budge the post cat, so I now need a new lambda with a flat plug.(anyone got one close by?) Air sensor is being delivered asap, should be here tomorrow. Just need the knock sensor due tomorrow and now all thats required should be the new lambda. should be ready to start then.. Need to get the clams on

i got my lambdas that obviously arent in an exhaust that you can borrow again might be worth leaving the engine to run then turn it off and then try to undo it failure to that take it to an exhaust guy and give him a tenner to take it out with a nice blowtorch! but if you want to borrow mine its fine i just have no idea if im going to be able to get it to you... as working the most hurrendous hours this week i can leave it out for you to collect though?
