240Z Turbo

Several things to think about: Do you have enough preload on the wastegate actuator? Is it a dual port actuator? If you can't make boost then you may be leaking exhaust around the turbo through a partially open flapper valve assembly. It is very possible you have a boost leak on your IC piping. Check all of your silicone couplers to make sure they are overlapping the hard pipe and that they are not torn. Seen this happen many times. Unplug the line to the actuator and it should see mega boost. Just do a short run in 2nd gear to see if boost spikes past the desired 14psi. If it does then you have issues with the manual boost controller. There are only a finite number of things it can be. It will not be related to the fact that you went to a larger exuast.

Agreed, seems to be most economical solution. No need to sleeve block on 400rwhp and no need to overbore that large as it really buys you very little.

That's what she said

That makes sense, then you pay out the nose for the information YOU provided. They provide nothing better than what I have seen many on this forum do in their garage. McKinney's interest, as it should be, is in the buck. Try to support each other in your efforts.

the pan fabrication("pro-typin") has little to do with cost and everything to do with abilities and resources. I made 10 of them with no problem.

Matt, I almost reconsidered doing the swap when ATI wasn't sure whether they could make the 8" race converter stall low enough for a street application. I didn't want to burn up the converter by having it constantly slipping. They have assured me that we can get a 5K stall on the converter and be usable for a daily driver. My buddy has one in his RB25 powered S13 so I will get first hand knowledge of its performance. It will be quite a while before I have mine running. Perhaps as long as 1 year. Send me an e-mail for the Tranny adapter stuff. Here are a few pics of the new CASA.

No secret, the guy never shipped me the remaining parts from the front clip.

Look underneath the intercooler

Joel, See anything in the pic that belongs to you?

Since the motor is off being built I thought I would start with the intercooler. Same core as Joel's, 24"x12"x4.5" fed by my GT42R. Build is as follows: Endyne Head (inconel ex/SS intake)/HKS 280 10.25's/Ferrea valvetrain/Findanza Cam gears Carillo Rods Endyne Custom Pistons(weisco forgings) ATI 800hp dampner My custom pan GT42R custom 321SS/Inconel exhaust manifold Custom dual plenum intake with dual 70mm TB's 160lb Bosch injectors Tech 3 custom fuel rail N1 water pump Nismo oil pump ATI GM tranny adapter (SFI flexplate/8" race converter) JW bell with turbo 400 (full manual transbrake) Am I forgetting anything? BTW, anyone need a complete Ka24de setup? tranny, ecu, motor, yada yada yada? $500 and runs like a champ. I want to spare no expense on this project.

Joel, The pan is looking good. As far as the ac, you could have used an intermediate mounting plate to move the compressor up .5"-.75". That may help to solve the problem.

RB26DETT Head - Part # ARP202-4207 Rod - 300zx TT Main - ?

I can't be blamed for that one!

For all the money you paid to have the swap done, the guy should have made sure the front turbo did not hit the hood. I would drive to his house and kick his a$$. BTW, congratulations on the recent results. Green Tea BABY!

Me have some of the necessary pans.

Please see classifieds under engine parts http://classifieds.hybridz.org/showcat.php?cat=17

Technically no, but requests were made. I don't want to finish the pans because my plate is full. For those that want to fab the pickup and baffles they can purchase a nice pan for cheap.

Jamie, I have made 10 of these pans so they are available without baffling if anyone is interested in purchasing one. You will need to fab your own pickup and baffling. Cost is $300. It is best to make a solid jig to bolt it to while welding. Otherwise it will have warpage on the flange. All the pans I did came out virtually flat by bolting it to the jig while welding. Nice job...looks familiar.

That compressor wheel was designed to work with the B housing. That is not to say you couldn't shove some massive wheel in an e-housing and it would then flow more. Don't let the fact that the e-housing is smaller in diameter fool you. It is much thicker than the e-housing. The twinturbo ZR-1 corvette project I just finished uses 2x GT30R turbocharger with 55lb/min wheels that we ended up using B-housings because of space limitations. The car made 565hp@wheels with 7.5psi of boost. My buddies Z31 turbo made 375hp/409ft-lbs @wheels at 19psi with this same turbo and that was on pump gas. BTW, he only had the stage III turbine wheel. You won't be disappointed.

Jamie, Those are my desired numbers. He told me the 2JZ heads only flow ~225cfm stock and fully worked they are getting about 318cfm on the intake ports. Now, the Honda B-series heads are another story. He is able to get ~380cfm from the intake ports on those heads. His initial comments were the combustion chambers were deep as compared to the Honda B-series or the 2JZ. This is not optimal for reducing detonation. However, unlike the 2JZ head the intake ports for the RB are straight. We will have a thorough discussion regarding the head Tuesday once his plate is clear. They do very nice work and I have high expectations.

I had Matt send me a pair of 280/10.25's from HKS. I will have the head modded to accept 11.25's if I choose to upgrade later. Head is currently at Endyne for some major porting. Shooting for ~325cfm on the intake ports. I purchased the following parts for the head: HKS 280/10.2's Ferrea Springs Ferrea Titanium Retainers Ferrea Seat Locators Fidanza Cam gears Endyne Custom Inconel Exhaust Valves Endyne Custom Stainless Intake Valves Depending on their recommendation I may have them make me a custom set of pistons to optimize combustion efficiency. That would mean I need to sell my current JE forged setup. Don't ask about progress, it will be atleast a 3-4 month before we have information. He has my head and parts along with my spare head that I have given them permission to do with as they require.
