12a street port weber dcoe blow thru project
Ive got a very cean very nice 1982 12a RX7. But its gettin tooo damn slow now.
I took the stock 12A out last weekend and replaced it with a street ported 12A I got from a friend.
(some of you might know him, Karism, hes bussy sticken a 13B in a beatle. )www.rx7club.com/forum/showthread.php?t=659739
We got no idea who done the porting or if its done right or not. The engine starts damn easy and idles 700rpm no problem.
Took it out for a drive and was absolutaly dissapointed, its even slower than the stock one. Keepin in mind I`m still using a Nikki.
So I played with the timing but didnt realy make a dif.
I know I`m supposed to change the jets and all but would it realy make that big a dif?
Me and my friend talked about it and recon that the axhaust ports might be to big.
So, bein a turbo lover I thought about stikken a gen2 series 4 stock turbo on it and do a blow thru carby jobby.
Readin a bit on here I realized that the Nikki would be way to pain in the **** to do so I`m thinking of a weber DCOE.
I know there are a lot of blow thrus out there and would love it if anybody could point me in da right direction. I have a 40 weber but I know poeple gonna say its too small.
saying this, we had a 40 dellorto dceo(modified) in his mild bridge and it did loads better than a modified nikki.
But, anyway, please anybody any ideas. I dont realy wanna go FI, some of us have a small budget.
Karism, my friend, has been on here a while now so I thought joinen the club would be damn cool!

before we stuck the engine in I had a feel at the ports and you can see in the intake side of the ports they are much bigger than standard.
Also the exhausts are loads bigger too. What I did look for on the exhaust is wether its been ported upwards or lower and by the looks of it it looks like its been ported lower.
I drive a `99 Golf GTi, and I wasted it with my stock 12A. Now, with this SP, I only just beat it.
