Todd,

Bought one (intercooler) ;like stock RX7 – nearly square $150 new. Had no hope of fitting. As usual only found out when I went to see where I would put it. Then bought a long one 16 inches by 8 inches and 2.5 inches thick. Once the factory ends are added in it grows to nearly 21 inches long. That however can be modified by replacing the “straight through” with a 90 degree at each end. That hopefully will give the whole intercooler blowing full length down over the exhaust manifold and the turbo. Spent most of the day making up an oil drain for the turbo as only have 1.5 inches drop into the top of the oil pan. Making it enter at the front plate just above the sump. There is just nowhere else!! Took some photos today of the spare turbo, and if it can be believed the stock oil drain enters halfway up the rotor housing?? Bel;ieve the drain has been bent. Will post shortly to verify it is a fake?

Neil.

My housing is stock with the exception of the wastegate porting that I did myself. It will come up far short of your HP expectations.

But Neil, what intercooler did you find? I'm just reconsidering my intercooler and considering other options.

James,
2 flying that I know of – Todd Bartrim and Dave leonnard. Think they have the standard RX7 Hitachi turbo. Just been around the world trying to get an affordable turbo for my renesis which does not exist if you talk to drag racers etc., Quotes between $4500 and $6500. Bought 2 hitachi turbos for $125 and one looks set to go while the other will need bearings.
There was an offer of one in south Africa for freight only. Would be a bargain. Just hooking mine up now, but as usual much to go that I have not factored as usual. Finally found an intercooler that may fit.
Best, Neil.

Does anyone out there have any recommendations for a turbo (brand and size) for a 13b in an aircraft? 300-400 hp range. Reasons or experience is appreciated! Auto racers have their needs but are different from aircraft... or so I've heard. My 13b's are nearing the decision stage for turbos. Thanks, James Whitehurst
