Stredrotor's RX4 Coupe * Project 20B *

Stredrotor · 02-20-2010, 05:12 AM

I got the exhaust manifold back from having the sealing faces machined flat so I have been able to make the 3 1/2 inch dump pipe, a tight fit but it clears

. Just have to make the flanges to bolt the exhaust system to it. (When I make the exhaust system.)

After I weld the flanges on, the turbo exhaust housing, manifold and dump pipe will be sent off to be ceramic coated. Should help keep the heat down and looking good.

.....also mounted the coils

Damn nice build, ive always had a soft spot for Rx4's and this one is sure to be the nicest ive seen.

A bit off subject, but will a RX4 bellhousing fit a 20b? And what does a series 5 trans come out of? Nice build by the way.

An RX4 bell housing would fit a 20b but the later FC Turbo models onwards gearboxes run a larger flywheel so have more friction surface the clutch to grip.

Sorry, you guys know the series 5 RX7 as the second version of the FC RX7 model. It is often related to in Australia as First Gen RX7 as Series 1,2 and 3 Second Gen (FC) Series 4 and 5 and Third Gen (FD) as 6,7 and 8.

thanks for the info. I looking for options on transmissions to hold a 20b's power.

We use that to. We usually just say "S5" though.

Amazing. Updates?

Stredrotor · 04-04-2010, 09:20 PM

Haven't had much time to work on it lately

. I have decided to remake the dump pipe it came a bit too close to the brake lines.

I am chasing a throttle body so I can make a start on the water to air intercooler setup.

Plus I said yes to make a 20b turbo manifold for a guy in Melbourne

but it's extra cash and I learned a few things from making mine.

Excellent work man! I look forward to seeing some updates.

What are you going to do for brakes and rear end?

Not sure yet, like to have a good disk brake setup.

Here's a bit of an update not much but it's one step at a time

.

Lashed out on a Westside Exhaust and Custom radiator and oil cooler combo.

Also a PWR barrel cooler, heat exchanger, filler spout and water pump I scored for a good price off ebay.

Now have to make some mounts for the radiator and heat exchanger and plumb up the barrel cooler.

Getting there ever so slowly.

Stredrotor · 05-29-2010, 03:49 AM

Found a bit of time this arvo, so with the mounts welded on I mounted the radiator and made some trial mounts for the heat exchanger radiator.

Also had a bend welded onto the end of the barrel cooler to bring it in line with the radiator.

Waiting on a 135 degree bend from plasmaman to go up to the throttle body to finish it off the intake side.
