This should be a pretty good comparison between the EFR and GTX turbos. I have a very similar build going on, 2.34L but with +4mm rods in a Benson sleeved block, DPR ported S20 heads w/ Cosworth 272 cams, ported intake mani and TB, custom reverse manifold FMIC, Full Race TS EFR 7670 turbo kit, Link G4 standalone ecu.

I'm trying to get the car on the dyno this week or the next at the latest for a pump 91 and Q16 tune. I'm not even going to speculate as to how much power I'm going to put down but I would like to see how our two car compare in terms of boost threshold, response, and power.

When do you think the car will be up and running? I have about 1600 miles on mine of WG spring pressure driving ~14 psi.

Hoping by spring. I am boxing up the heads today and have been doing all the super tedious stuff to avoid studying for finals.

I think my biggest hold up will be wiring and hoses. I pulled the harness so I can tuck/ reroute some stuff, but really need the engine together for that. After staring at summit this weekend for fittings I don't really want to pull the trigger on hoses until I see it in the bay too so I know what I'm working with.

Until I get the heads back I'll keep cleaning and rebuilding things. My goal is to have everything boxed up clean and with its associated gaskets so I can just grab "water pump box" and install it, then "timing belt box" etc.

This is the 5th time this year so I'm getting pretty quick.

Why the "mismatched" camshafts? The 268 GSC intake is from their S1 and the 272 GSC exhaust is from the S2?

No e85 around here. I'm not that power hungry either, like I said it'll be more than I had before and more than any car I've owned in the past.

Did you see the good news (for you) that Dom is moving to Ohio? I might make a trip up for a tune.

ANNOUNCEMENT: For those that don't already know, I'm moving to Ohio to be closer to my daughter. She turns 11 in January and I haven't seen her near enough in the last 8 years. It's time I get more involved in her life.

So what does that mean for my customers, I hear you ask.
Well, I'm joining forces with TurninConcepts. They just opened up in a new, larger facility and I'll be there heading up tuning, engine building and a few R&D projects. This means that the engine build quality you've grown to appreciate from Maxwell Power will still be available. Initially, there will be a few MPS branded products that will be available from TiC. Eventually, all products and services will be 100% under the TiC name. Once at TiC, I will be able to provide better support and services than before. I will not be spending hours a day as the business owner doing paperwork or answering all the sales calls. TiC has people for that. This means that I'll be able to be more efficient and spend more time on the tasks that only I can accomplish. This is one of the most exciting aspects as I can finally spend all my work time helping customers . For my prior and existing customers, I'll still be offering support for you guys as if I never left. It'll be more like I moved my shop.

Be prepared for some new and exciting products from the new TiC crew.

Timeline? Currently the amount of work here at the shop is more than can be handled by the initial goal of January 1st, 2014. Once I get these cars finished for my customers, I then have the monumentous task of selling inventory, tools, lifts, dyno, equipment, cars, etc that aren't going with me.

If you'd like a tune before I move, please call the shop. I'd love to get you taken care of before I go. Slots are limited as I still have lots of work to do here on the floor. I have several long term project cars that need to be completed before my departure. This means that large chunks of time are already blocked off for that work. If you're reading this and you're one of those customers with a car here: You are my priority.

Will I come back? Yes, for a week at a time or so. I have already arranged facilities for doing dyno tuning trips to this region and the Spokane region.

On a personal note, I'm very excited. Not just to see my daughter more, but to able to represent such a great company like TiC and bring more DomTunes east of the Mississippi. Currently, however, a lot of my excitement is overshadowed by the stress of such a life changing event. I had not anticipated this being as hard as it is and I'm doing my best to help my friends, family and customers with the transition. However, in the foray, I need to also take care of myself and ensure that I get everything taken care of that needs to be handled. So please be understanding.

To the PNW specifically: I love you guys (and gals). Thank you for making this area a place I was proud to call home. The public support out here is amazing. I'll be a Seahawks fan for life.

Thank you all,
Dominic

Looks to be a similar build to mine with the exception of closed deck and I have a GTX35.

Do you think that Walbro is going to do the job?

3582 or 3576?

Yeah I think the walbro will be fine for the 1000cc. I only run pump since there is no e85 around.

3582

I too plan on running only pump 93, but I'm probably shooting for a bit more power.

Dusted off some boxes yesterday. Just waiting on the mail man now.

Next hold up will be setting the lash and ordering the buckets.

Finally got a legit tune on the 2.34L build. Hurry up and get tuned so we can compare.

I am ready to shim the heads, but a slight change of plans has me waiting on the mailman.

Out with the standard ARP's in with some CA625+

This turbo shows it "stuff" at higher boost. So the C16 will be the test.

Still can't find a tuner either. I've tried Scott Siegel who tunes at Forged only on Monday nights. I know he has some experience tuning Matt Ball's old destroked and LR setups.

Might make a trip to see Dom and TiC or see about him coming here.

I'd like someone with some experience with 2.3's as I don't want a blah AVCS map.

Made some progress albeit one step forward two steps back.

Oil pump is packed and ready to go.



Installed heads to measure valve lash only to find some as tight as .005" with the thinnest bucket. So I pulled all that to have them tipped.

This weekend I tried to get back to where I left off. Greased up the valves put them back in the heads the other day just as a place holder. Didn't notice anything wrong until Saturday when I went to put the springs in and 4 of the valve seals had torn.

Completely rebuilt them only to run into some problems torquing them down.





The icing on the cake lies here. I didn't really pay much attention to this before as it never made contact, but damn its close. Not sure if they should come off again and be clearanced. Ugh




the other's are about like this.
