Hey Guys, Just wondering.. I bought a high 265in 8mm lift intake cam(only) from Speedvision along with their adjustable pulley. I understand that we'd get to adjust the power band for a twin-cam two pulley engine, but how do we go about setting the timing for our 4efte? It's got ten marks...

Hi guys, I recently ordered two sets of forgies. I made an order of 75mm Ross piston and rings for my 4e and a friends'. What came in the package was a 74mm piston set with 75mm rings. Are these suppose to make sense?

Hi guys, Just to share with you guys :). Made in Malaysia. Took 10days for fabrication :). Details and specifications : - Runners same size as oem - ALL runners as equal length as possible - Schedule10 Stainless steel - Turbo location...

Hi guys, Just got a speedvision 1.6mm metal HG, 5-layered steel. Question is, is it necessary to take off the rivets holding the gasket together, fitting them one by one onto the block with a layer of copper spray in between each layer? Another question would be ; What difference is that...

Hi guys, I was having some overheating problems on heavy loads(high throttle for 30secs, maintain at high speed) initially. My mechanic got the head out, skimmed the head(there was warpage), replaced the pistons rings and rod bearings and fit it all back. After doing some running in, I...

Hi guys, what does the IPV valve of a 4efte looks like, or do we even have one? Been looking online for some pictures and couldn't find one. All I know is that there is one other sensor that's located on the firewall other than the map sensor. This one has two vacuum hoses going into it, one...

Hi guys, I'm wondering if we can actually check if the IAT sensor is still functioning? I used a digital multimeter to check for resistance - success. But, when the engine is running and the socket plugged in, I didnt seem to get any resistance. Did i do something wrong? Am i supposed to...

Hey guys, Am in Malaysia here and would like to know if we're able to cruise at a 15.0AFR. Current setup was tuned at 11.5AFR on boost and 14.7AFR on cruising. I somehow notice an increase in fuel consumption after the tune when i put in a rrfpr and walbro 255lph. Also have a decat and...

Hi guys, I used to run on a stock fuel pump with 35-40psi on idle with a rrfpr. However, after replacing the existing weak pump with a Walbro 255lph pump, I cant seem to re-adjust the Sard rrfpr below 60psi lol. Any idea why cant I? The car is running extremely rich now. I have an emanage...

Hi guys, Just to enquire, would a 35mm or 38mm wastegate would be suitable? Its gonna be 0.9bar stock ct9 :). Also, another questions is : say, a wastegate is rated 1.0 bar. So, does the wastegate opens gradually from .7 till 1bar, or just slaps itself open instantly at 1bar? If we...

Hi guys, I just fitted a manual boost controller. Prob is, im overboosting alhough the bleeder is fully closed anti clockwise. I thought this was the prob : ball and spring in the t-joint. Therefore i took it off, but still gettin the same results. I fitted it onto the outter hose of the...

Dear Sir, I want to install a Haltech platinum interceptor on a 4efte. I have a unit in hand and i I am having problems creating a wiring diagram, confused between anologue and digital input signals. I have tried to trace and make a diagram from an evo8 but failed. Do you think you can...

Guys, As far as i can remember during my last rebuild, i purchased a set of pistons which were domed on top. I skimmed em flat already, probably from a 5efe. Jut aftermarket 74.5mm ones. Queestion is, after shaving em flat, whats the compression now? Will the pistons be reliable for .9bar...

Hi Guys, I recently removed my cat. The O2 sensor is back in, but is it necessary to re-fit the second sensor? I mean the other sensor that screws into the exhaust as well, thats after the 02 sensor. Or Just unplug it and leave it at home? Currently running it unplugged, no check light no...

Guys, I did an engine rebuild about 14k km ago. Did a power run and got 119bhp on a dynojet. At one stage, i couldnt idle my car when aircond was off, and realised that the TPS wasnt plugged in tight enough. This was about a month ago. I plugged it in and removed the EFI fuse overnight...

As per title says, is it possible? Dont think they have a base map for our 4efte. As i know not too much to expect from a piggyback; How much improvement in terms of fuel consumption, performance and reliability can we get from this? My country running on Ron95 fuel lol and i got a totally...

Anyone using engine PU mountings all three pieces, or maybe just for the gearbox size or firewall side? Hows the vibration gonna be? Thinking of rebuilding my torn rubber ones with PU compared to purchasing new ones.

Hey mates, Had 78-85psi across all four cylinders after compression test. Decided to strip the engine and found out that piston no.2 and no.4 are cracked at the ringlands below the intake side (the two grooves for the valves) of the piston. Smoke comes out from the breather hose, but not...

Heard that no matter how we tune, our engine's fuelling is linked to our ignition, hence the self learning ability of our ECU will revert the fuelling back to its original settings even after tuning the saFC?
