if you check out the rrotaryheads website, i've got my contact# on there. we've got a lot of options for doing an engine. i've even got almost enough parts to build one in advance and ship it out to save on downtime.

since i've got an engine with intake and exhaust ported already, how about i build you one with just the exhaust ported, and the intake left untouched? that should build extra power through efficiency, but not have to use any extra air... that might be a good trial for keeping all the ecu stuff stock.

naw, pulling the engine is an absolute piece of cake. it's easiser than any of the 2nd and 3rd gen rx7's.
i'm wondering if you've considered using alcohol, instead of gasoline with a wet nitrous kit. i think that'd give all sorts of headroom for a larger nitrous hit.

really bad thread to bump with a bad question.
Dave the original poster died in a car accident.
this is a simple question so ill just answer it. there are only a few hp (3 maybe) to gain from a new exhaust. nothing you will feel, mainly just a different sound. please use the search function for simple questions like this next time

i know all about the accident, and it is definetly a damn shame, not only because of his passing but also because i, along with everyone on this message board, was looking forward to those results and i was just curious if anyone else has done this yet.
wow i feel like a moron... what I meant to ask was hp gain with the engine ported, not stock. sorry about the misunderstanding.... i already have an aftermarket exhaust and it was a total waste of money, other than the nice sound. i'd just like to make it worth while and bridge port the engine. I have a machinist that will do it but he would like exact specs from me. anyone know where I can get those?

just on a whim, i called acosta motorsports and asked them if they have ever ported a renesis... and guess what! they do a mild port for $4200 with a 30whp gain, or an aggressive port with custom intake and headers for $6500 and up with a 300whp potential!! its crazy pricey but everyone has seen their beautiful 20b swap, and i'm sure they will do a custom turbo setup (i forgot to ask) that can push another 250+ extra horses out! any questions call acosta @ (201) 791-2204

yeah its definetly pricey, but at least now we know it's full potential with a race ported NA setup. $4200 is rediculous for an engine rebuild with a mild port job, i'd rather buy a set of housings and race port them myself. only problem is u still need custom intake/headers to reach ithe engine's potential (possibly getting rid of that ugly plastic upper). plus i'm not an expert by any means in porting, so i would be nervous about taking too much off the housings. too bad there were never any kind of templates made available before Dave's passing.

I can bet my life you will not get 30 hp just from porting. from the looks of it and from what people are talking the only thing you can port is the exhaust .

I don't care who claims what, you aren't going to get 300 hp from just porting, intake, and exhaust on a Renesis. It won't happen. A full peripheral port motor is a different story but that wouldn't be a Renesis anymore.

from my discussions with dave, he said that this thread was still inconclusive. thats why he was going to do it to his own motor in hopes of getting more definitive answers. its also why he refused to port my motor until he was sure that he could produce gains with his own.
if i remember correctly, he said the porting alone gave about 14hp to the wheels and the CZ added another 15 or so. BUT... the dynos were done several days apart and the initial dyno was a bit on the low side.
