240Z Turbo

Has it only been 8 months He did call me about 3-4 weeks ago and tell me he was at 235cfm on the intake ports, but did not give me the lift value. He said the velocity had improved over stock at that point and he would continue to 245cfm and then stop. BTW, this was with a modified E88 head. I figure 8 more months and he will start the P-90 head I gave him

Jeff, The GT25R's we will be using on Joel's car are not the standard GT25R turbos. These utilize the T04S compressor housing with a 48-trim GT compressor wheel that flows 44 lbs/min as opposed to 26 lbs/min of the stock GT25R turbo. This setup provides good spool characteristics of smaller turbos, but will support about 900hp. What I can offer is to make two headers when Joel's car comes to town. His will be made from 321SS using the fancy merge collectors. The header will be in the $1500 range as the material is about $1000. I do not need the car to do the intake manifold. When it is almost complete I can send it to you and you can mark the final angles for the throttle body and send it back to me. The intake is not hard to make, it is just somewhat labor intensive. It will cost about $750 to do the intake manifold and modify the fuel rail. That will include the powder coating as well. You just need to give me 2-3 weeks on the intake manifold. Send me an e-mail if you are interested.

Jeff, I am always willing if the price is right. I am doing this for Joel very cheap to help promote my new website: http://www.speedshopthagard.com I have about 8hrs into it thus far with about 2 remaining. The VS's are said to add 3-5% flow. If you look at the Jun and other fancy RB26 intakes they all utilize velocity stacks on the inside. I made an intake for an SR20DET'd RX7 with a similar design and it laid down 585hp@wheels with no head porting and went 10.5@139.2.

Need to polish some of the welds and then a few more mods and ready for powdercoating.

22psi on pump gas Tim is going to buy a new GT4240R from me very soon. This car will make 600hp@wheels with the new turbo and cam.

Pete, Yes, that is a complete turbo using all new Garrett Parts. The T3/T04E stuff comes straight from Garrett in the Garrett box. Please check out my site for complete information. http://www.speedshopthagard.com

I finally welded all the velocity stacks onto the flange and bolted it to the manifold. Looking good thus far. One note, the #6 port on the plenum flange angles alot so I had to weld material onto the inside of the runner so it didn't have a big step. I will now have to go back and grind it back so it matches the transition of the velocity stack. You can see from the side pic the angling of the plenum flange #6 runner.

Truck applications had the T4, but hybrid turbo's did not come on OEM applications. I am now a Garrett Dealer and sell brand new Garrett T3/T04E turbos for $549+shipping. http://www.SpeedShopThagard.com

I used to be a HybridZ Guru, now I get 2 of 5 circles next to my name I'm like the movie nobody wants to see

What did you expect It will look very nice when it is finished and coated

Sorry Joel, the lathe ate one of the velocity stacks

I had the flange decked and just mocked up the velocity stacks that arrived today. Will make the backplate and weld on the velocity stacks. Getting closer!

Joel sent me his intake to do a bit of massaging. I modified the stock fuel rail by cutting off the ends and tig welding some -8 an fittings. These feed the rail from either side by a pair of Pierburg 600hp pumps. We then went with a single outlet in the middle of the rail by tig welding a -8 an fitting. I also removed all the extra junk on the rail. It will be powder coated for better looks. We opted to remove the stock throttle bodies in favor of a single 80mm unit. I have hacked off the plenum flange and will bolt it directly to the intake base. I will deck the flange in a mill next week. We ordered 6x full radius velocity stacks to weld to the plenum flange. Once this is done I will make a custom plenum for this badboy. Since I am now a Garrett Dealer I am trying my best to talk him into a pair of GT25R turbochargers that each support 440hp! I will be fabricating a custom 321SS header for this badboy

Are you running a 60-1 compressor or are you running a 60trim T04S? I think both compressor wheels flow the same, about 60lb/min. It has been a while, but I think you want to run the stage V stuff on the turbine side. Where are you purchasing the turbo? Send me an e-mail as I can get you new Garrett turbo's for cheap.

I have one of these heads. The combustion chambers are ideal shape for performance with the large squish area. Minimal reshaping is required. However, the intake ports aren't big enough to put my into. I paid $75 for mine while in New Zealand. They had all the heads we could not get, E30, N33, O5L, etc. TonyD, bet I can outbid you on the head!

Does this help?

300zx n/a is actually 4.09:1...sorry, I have one in my folks garage. All other information is correct about the R230.

The non-ring geared flexplate cost $50 The T6061 tranny adapter is $325 The flexplate adapter will cost $60-$80 (I machined the initial aluminum prototype) After I get it running I will sell it as a kit.

Now all I need is my Powerglide transmission Stock automatic flexplate jobby goes onto the crank first Next use stock 280zxt flexplate for use with high-torque starter My custom flexplate spacer/adapter goes next Finally, the Wilcap flexplate. You can notice it has no ring gear.

The LD is not a direct boltup. the runners match the stock gasket size so they are indeed bigger. However, you will have to slot the mounting holes about 1/4" to make it line up with the port on the non-LD head. Also, no provisions for injectors because it is diesel.

FYI, a GT2530 is very small. It is a GT25 turbo that flows 30lb/min or about 325hp max. Those are HKS designations for the GT stuff. Check out this link on the GT stuff. http://www.turbofast.com.au/GTseries.html
