here's a few pic's of some parts I've been working on
1700 heads I've modified at work, from this to this (machined step & groove), chamber porting was done at home , needed more cc (61) to get compression down custom 100mm JE pistons ( thank you Charles @ LN engineering) machined piston crown pocket (9cc) |

Here's a few more details ( parts that I have acquired )

(61cc chambers with 9cc dish in piston ) with .038 deck pauter cam K8O3 on 110* LC, in. 288* adv. /255@.050 x .384 lobe lift , ex.296* adv. /268@.050 x .398 lobe lift type 4 rockers 1.3 with porsche adj. on order from KEP (kennedy engineered products) 228mm twin disc system with organic pads for streetable use 1-7/8 4-2-1 CFR Tangerine exaust , will modify with flange coupling for turbo ( its probably to big but its what I have to work with ,its on my running 2.8 ) putting together a HORIZONTAL fan shroud system (I picked up a incomplete kit ) extra set of cb 48mm throttle bodies with hats megasquirt2 exta inj & ign. (running in car on 2.8 twinplug) I also have a cb quicktune system & a mallory unilite distributor (lockable) still need turbocharger (trying to FIGURE out which one) water meth injection air to air intercooler plus more I cant think of this is my first attempt at a turbo motor so I'm sure I'll make a few mistakes along the way , my plan is low boost with 9to1 cr , along with the small ports on the 1700 heads allowing for snappier throttle response maybe quicker spool ? |
