TECH: 4A-GE ENGINE • Re: Return #5: Spare engine boogaloo
The collector design is your typical straight wall tube. To develop a reflective wave the at the end of the collector it must open into the atmosphere, and NOT into your typical tail pipe. The other option is to dump the exhaust into a large canister. Which is next to impossible to package! The ideal […]

Not a fan of test beds for engine break-in. You can't put a load on them to properly break in the rings.Statistics: Posted by oldeskewltoy — Wed Apr 17, 2024 1:07 pm

Thank you! Although I'm not quite sure I understand all the terms well enough to actually make sense of this.Am I right to assume this is the softwares suggestion to what diameter and length the primaries should be to attain the specified results?davew7 wrote:--- Single Primary Pipe Specs --- ( Low to Mid-Range RPM Torque […]

Here is the exhaust spec's that maybe helpful. Pipemax : This output is for a stock BT in low overlap VVT position. Pipemax is about as close as you are going to get to that type of fancy maths estimating real world results. Cylinder Ignition Interval = 180 degrees 8000 RPM Hertz frequency = 66.7 […]
TECH: 4A-GE ENGINE • Re: Return #5: Spare engine boogaloo
I surely can't afford custom fabrication from a company. My friend will help me build a set of headers. The rusted one I have uses a pipe diameter of 38 mm, if that's good enough for Martelius, I'm sure that's the right diameter for me too. The header will use 38 mm primaries into a […]

OWNERS and BUILDERS • Saving a crusty 16v 4age
It's a slow day here at work, and I realized I haven't shared anything on the spare engine I've been slowly rebuilding over the past 2.5 years. This is my first time breaking an engine down to bare components and rebuilding it, so this is more of a learning experience than anything. This is going […]

You can talk to Martelius and see if they can do something suitable. According to MRP (who sell these in NZ)... "For ease of shipping and installation, this header comes in 3 pieces and is just slipped together, then bolted in place". That might help if the header has to straddle the steering column. Currently […]
TECH: 4A-GE ENGINE • Re: Return #5: Spare engine boogaloo
It's been a while. Believe it or not, this engine is still going strong. It was time to get rid of the ol' recirculating ball steering for a proper rack and pinion. I got a hold of a crossmember with rack and steering column from a TA60 Carina. Matched that with the stock control arms, […]
