Rb20det Problems

[l0r0de0]

Having troubles with an engine conversion i am doing. I've got a holden rodeo minitruck which I have

installed an rb20det silvertop from an r32 using the skyline 5spd box and custom tailshaft.

The only bits that aren't factory are the s/s top mount turbo exh manifold with 38mm ext wastegate.

T3/T4 hybrid turbo (i think), 3" dump pipe & 3" exhaust and exceedy h/d clutch.

It's all hooked up, plumbed up, ready to go..... the problem i'm having is that ran rather well when I

had the garden hose shoved into it and cold water circulating through the engine. Revved freely and

sounded really good. I put the radiator and 16" thermo fan on it and straight away running like shit,

hesitates, coughs, farts and is hard to start!?

I've pulled a fair bit of shit apart and can't find anything, any help would be greatly appreciated

Oh, also i dont have an o2 sensor yet, doubt that's the problem, but i've been wrong b4

mmm i can say that the engine will be fine without the o2 sensor (dump pipe). drove around all day today with mine unplugged...so it can't be that.

ECU tuned for that stuff? if you just whacked them on you may have busted something..

If so, have you taken the power or signal for the thermo from anywhere funny? checked all connections etc?

I installed an o2 sensor and it slightly improved things, still far from good. All connections are good, thermo fan is not the problem.

Checked fuel pressure? You haven't inadvertantly fouled your plugs when trying to get the motor going? Checked the ECU for fault codes?

my question would be why would you prefur a rodeo over an R32? lol
