My brother has an 89 rx7. We made up stainless exhaust 3" muffler where the cat was , and twin 2 1/2 " out the back with 4" tail pipes. Also fitted a K&N filter and got a power FC. We were about to install a front mount intercooler when we had some spare time , then the engine did a water seal..

So we had a bit of time to do it.

Engine bay with some bits taken out.

Reason for water seal going... corroded side plates where the waterseals go and the rotor housings were showing there age so we replaced them with new ones and gave them a mild street port before assembling.

The rotors were slotted to 3mm .

We had an T70/t3 turbo and 50mm wastegate hanging round and one of the exhaust manifolds we make , so we figured why not, and we polished all the manifolds , alt etc . We didnt paint the block or polish the housings to give it that " it could be stock look " and put a new 4 kg chrome moly flywheel and sports clutch.

Then we modified a gtir pulsar intercooler to fit in the front , remounted the relays and made an alloy cover to cover it all up and duct air into radiator. We made the plumbing from stainless steel and made a new battary tray that sits over the top of it . The throtle body hat we also make which is 3" to match the plumbing. For the BOV we use trust type r .

Kept the power steering but ditched the air con . The plastic ontop of the radiator looked like it was ready to split so we made an alloy tank for it and fitted a 16" fan.

To control the boost its got a blitz dual solinoid boost controller.

Extra fuel is taken care of with 700cc blitz injectors.

Also every thing hot has got multi layer stainless heatshields around it .

looks nice and clean. me want!

Holy crap, you make it sound easy. Nice work!

Fantastic, you boys down under make quick with the go-go...

i applaud you for using new core parts. you set a good example to all the cheap bastards. lot's of work in that bay. one suggestion though, replace the plastic water neck.

Agreed. I recently made a few but havent got around to fitting one.
